District parking management program (a)
With the new era of community management requirements, intelligent community, safe community gradually become the urgent call of the times residents, intelligent parking systems and other series of security equipment combined to provide an effective way to build intelligent community, safe community, through the scientific management approach to achieve intelligent community management has become the mainstream.
The following is the realization of the community parking system program
First, the main materials for engineering and construction, tool requirements
1, access control machines, automatic gates and other packaging should be intact, the appearance of the material should not be damaged, accessories, spare parts, tools should be complete;
2, engineering and construction cabling standards, wire specifications, should be in line with the parking lot project design requirements and the relevant provisions of the standard parking lot. And standard parking lot regulations;
3, carry a good complete set of relevant documents, and information.
Second, engineering and construction wiring technology requirements for parking system wiring not only requires safe and reliable, but also to make the line layout is reasonable, neat, solid installation. Cable installation in the building to maintain horizontal or vertical, and should be added to protect the casing and make the cable fixed secure and beautiful; 220V power and signal lines to be laid separately, not to wear in the same pipe, the distance is greater than 50CM.
And all the lines must be casing, PVC pipe and galvanized pipe can be, to avoid rats bite off the line caused by failure.
If there is a break point in the middle of the line, you need to weld the break point with a soldering iron and do a good job of insulating the process; wiring must be labeled on the cable to facilitate future installation, commissioning and maintenance.
Power line entrance/exit gate, entrance/exit control machine needs 220V power supply, using three-core shielded wire (RVVP3 * 1.5), generally received a dedicated line UPS dedicated line power supply, in some cases AC220V power supply can also be connected to the nearest, but should be in line with the relevant norms to ensure that the system in the AC220V socket in the ground line true grounding.
Networking line
Parking lot networking can be divided into: 485 communication, TCP/IP communication, RS422 communication, etc. 485 networking line must be shielded twisted-pair cable RVVSP2 * 0.5, 485 bus length, theoretically up to 1200 meters, it is recommended that not more than 1000 meters.
If more than please choose 485HUB or repeater to improve the communication environment. In order to ensure the stability of communication, the end of the communication line connected to the resistor, or all the shielding layer is connected, the end can be suspended or connected to the ground according to the situation. 485 network must be a bus-type structure, do not allow all or part of the star structure. tcp / ip networking line can choose the super five unshielded twisted pair, the distance from the controller to the switch or the HUB to be less than 100 meters.

Third, engineering and construction piping (groove) technical requirements
Line pipe (groove) wiring has a bright line and two kinds of dark line, bright line pipe requires vertical and horizontal, neat and beautiful. Concealed piping requires short, smooth, less elbow. Line pipe (trunking) fixed, line pipe (trunking) in the turn or straight line distance of every more than 1.5 meters should be fixed.
In the box (box) does not enter the vertical pipe mouth, after penetrating the wire, the pipe mouth should be sealed. In the access control wiring straight pipe diameter utilization should be 50% ~ 60%, the pipe diameter utilization should be 40% ~ 50%. In the construction process, if there is a need to adjust the special circumstances of modification, must be recognized by the company leadership and customers before construction.
⑤ Determine the depth of grooving: if you choose 16mm PVC pipe, the depth of grooving 20-25mm; if you choose 20mm PVC pipe, the depth of grooving 25-30mm;
⑥ groove appearance requirements: horizontal and vertical, uniform size;
⑦ groove measurements: dark box and wiring box groove independent calculations, all the groove according to the groove from the beginning to the end of the groove measurements, if the groove start to the end of the groove, if the groove is the same, the groove will not be damaged, the groove will not be damaged. Measurement of the end of the slot, if the width of the slot is more than 80mm according to the length of the double slot;
⑧ groove sealing: after sealing the slot of the wall, the ground shall not be higher than the plane, should be level with the original plane.

VII. System checking and testing
Pre-installation check: Before installing the equipment, you need to check the equipment varieties and quantities of the installation contract in advance to make sure that there is no error and then collect the equipment from the warehouse. When the equipment from the warehouse out of the need to test all the equipment one by one, in order to detect whether the equipment is normal, to avoid trouble in the installation.
District parking management program (2)
The arrival of winter, bad weather will cause the community facilities and equipment to varying degrees of damage to the residents of the life of the adverse impact. In order to ensure safety, to prevent problems before they occur, the property company should be early arrangements, early prevention, in advance of the development of emergency programs, do a good job in winter "three prevention" (anti-freezing, leakage, anti-skidding) work, to ensure that the residents of the community normal life and safe travel.
First, anti-freezing
The arrival of winter, property management services, the first thing to do is to prevent freezing. Generally speaking, attention should be paid to vacant houses, *** with facilities, equipment and building insulation and other three aspects.
1, the vacant house anti-freeze
(1) property management service enterprises are responsible for the care of the ` vacant house anti-freeze. Some developers out of the trust of property management service enterprises and reduce the trouble of caring for the house, will not be sold or sold but did not handle the occupation of the house (especially commercial outlets), to the property management service enterprises to care for. For this type of housing, the following measures should be taken to avoid the upper and lower water pipelines frozen leakage water phenomenon
anti-freezing measures:
① Strengthening of indoor cold insulation. The external doors and windows of vacant houses (including balcony doors and windows) are inspected, and the missing glass should be replenished to ensure that the doors and windows are closed tightly. If necessary, the upper and lower water pipelines should also be insulated with rock wool and other thermal insulation materials, the closing of the windows and doors with grass mats, cotton curtains for sealing. Vacant commercial outlets without heating, the whole building on, down the water main line are in its indoor, once the frost damage, the affected is the whole building of the residents (users). Such accidents have been commonplace over the years. Therefore, property management services companies can not ignore the cold insulation, do not spare the cold insulation investment.
② Establishment of vacant house inspection system. Set up a person to patrol the vacant house, the general requirements of three days to patrol once, the longest time should also be a week to patrol once. Three nine cold on the key housing (such as vacant commercial outlets with **** facilities) should be patrolled once a day, found that the problem is promptly reported and resolved in a timely manner.
③ Establish an emergency mechanism. Before the winter to develop a practical emergency plan, the formation of emergency repair team, prepare emergency supplies and materials. Whether it is night or holiday, received an emergency report, the relevant personnel can rush to the scene as soon as possible to solve the problem occurred. Truly emergency not panic, handle properly, repair in time to avoid losses.
(2) developers of vacant housing frost prevention. As a result of sales or other reasons, there is no occupancy of vacant houses, the developer is responsible for looking after. Developers focus on the vacant houses and facilities and equipment is lost, property management service companies pay attention to these vacant houses do not bring damage to the rights and interests of others. Therefore, the property management service enterprises in the winter before the developer should communicate and negotiate to determine these vacant houses in winter care patrol approach and the occurrence of emergency programs. Clearly the two sides to deal with the vacant housing emergency responsible person and contact methods, the establishment of daily vacant housing care inspection of the two sides contact system. To ensure that the vacant housing situation is clear, the two sides of the emergency program is clear, mutual contact and communication in a timely manner, the implementation of emergency treatment quickly.
(3) the owners of vacant houses to prevent freezing. Regardless of what grade of the neighborhood, the owners of vacant houses are common phenomenon. The owners of these vacant houses, most of the lack of awareness of the importance of winter anti-freeze, negligent of vacant houses in time to see, and at the same time are not willing to inform their own relevant information to the community property management services or neighboring owners, resulting in the occurrence of an emergency can not be contacted the owners of vacant houses. Every year in winter, vacant housing water (heating pipes or water pipes freeze and crack, etc.) and can not find the owners of things happen from time to time, to the neighboring owners have brought greater damage. For such vacant houses, property management service enterprises in the winter before the owners of vacant houses should take the initiative to find, communication and consultation on how to view the vacant houses in winter, suggesting that the owners of the upper and lower water pipes and other thermal insulation measures, to determine the emergency solutions, mutual exchange of contact methods. At the same time to inform the owners of vacant houses in the event of emergencies, bringing damage to others when he should bear the responsibility. If there are no valuables in the vacant house, the property management service enterprises can also store the owner's house keys (need to be kept by a person), in case of emergencies when the use.
2, *** with the facilities, equipment, anti-freeze
Into the winter, the district *** with the facilities and equipment should also be good insulation anti-freeze measures. Upper and lower water pipelines, fire facilities, etc. Most in the building or house basement, winter is very easy to send seasonal frost damage: such as frozen water pipes caused by the water can not be, the fire temperature sensor alarm cracked caused by leakage and other phenomena, a lot of neighborhoods have occurred. Therefore, the property management service enterprises to these *** with facilities and equipment for insulation. Insulation methods available perlite block enclosure or rubber tubing, rock wool, brown hemp winding and tying. If necessary, hot air curtain facilities can also be installed at the entrance to the basement (or underground parking lot). These thermal insulation measures are once invested for many years to benefit.
3, building insulation should be given enough attention
Before winter, the building doors and windows should be closed tightly, missing glass in time to make up for the installation. Roof entrances and exits should also be closed tightly, if necessary, you can add lock protection. There is no door closer door should be installed door bow to achieve the floor door automatically back off.
Second, anti-leakage
Winter **** with parts of the leakage is mainly the roof and external wall water fall pipe location.
1, the prevention and control of roof leakage
The main part of the roof leakage in winter is the daughter wall waterproofing eaves and centralized drainage outlet two locations. The reason: a waterproofing eaves coil bonding is not firm with upturned gaps, in the roof snow melts into water over the edge of the coil, along the upturned gaps downward leakage; two is the drain is welded iron plate, coil pasted on the iron plate, winter cold iron plate and coil expansion coefficients are different, prone to the phenomenon of coil upturned. Roof snow melts into water flow, leakage along the warped place. In addition, the narrow drainage port, waterproof construction with certain difficulties, waterproof construction personnel negligence is not serious operation, is also one of the causes of winter leakage here.
The main method of prevention and control of roof leakage in winter:
① before winter carefully check the daughter wall waterproofing under the eaves of the coil with or without warping gaps, such as found that there are gaps in the application of waterproofing paste embedded filling to solid and dense shall prevail;
② double-check the drainage mouth of the iron plate with the coil adhesive in place, such as found to be not dense or not in place phenomenon should be baked immediately with a blowtorch or re-pasted! Waterproofing roll-roofing;
③ once the roof leakage in winter, to quickly remove the roof snow and water (ice), and then carefully clean up the leakage of ice and water droplets, if necessary, can be dried with a blowtorch, and then filled with waterproofing ointment.
2, the prevention and control of leakage of water fall pipe of the outer wall surface
Most of the roof is organized drainage, the snow on the roof surface dissolves into water in winter, and it is discharged into the water fall pipe of the outer wall by the drainage outlet of the roof surface. But the water fall pipe of the outer wall (especially the water fall pipe on the north wall surface) temperature is very low and very long, when the snow water flows down the water fall pipe, it freezes on the inner wall of the water fall pipe, and a layer of layer gradually becomes ice to block the whole water fall pipe, and then it expands to break the water fall pipe. It makes the snow water leak out and flow along the outer wall surface, and then freeze on the outer wall surface at night when it is cold. Cold in winter, the phenomenon of the formation of ice surface layer on the external wall can be seen everywhere, that is, from this.
The main method of water pipe leakage control:
① in the roof during the melting of snow, pay attention to the timely sweeping discharge of water, and in the dark near the end of the day, in the upper part of the water pipe with a stick to beat, will be bonded in the water pipe on the inner wall of the frozen layer of the vibration of the shock shock, to avoid the thicker the accumulation of ice blocked the entire water pipe;
② found on the surface of the external walls of the ice, the ice should be cleaned up in a timely manner. That is, to avoid falling ice injury, but also to reduce or avoid the wall here in the spring when the mold and hair.
Third, anti-skid
In winter, due to the cold weather, snow and ice on the road is very slippery, people traveling with great inconvenience. If you accidentally fall, easy to fall, resulting in safety accidents, so inform the owners of some winter anti-skid knowledge, timely and good warm tips.
1, anti-skid personnel:
① Timely removal of devices, roads, stairs, access to the snow, ice.
② Set up anti-skid facilities in the main channel, such as: anti-skid blanket, anti-skid mat and so on.
③In places where there is a risk of slipping to, set up a safety reminder banner.
④ Hold the handrail when going up and down the stairs.
⑤ Wear non-slip shoes when traveling on snowy winter days, and walk on the pedestrian steps on the road.
⑥ Walking in snowy weather should not be too fast, the stride should be small, hands should not be in the pocket, because the upper arm swinging back and forth can play a balancing role.
⑦ If the road really accidentally suddenly fell, try not to use the wrist to support the ground, because this fall posture is most likely to cause arm fractures. Once the fall occurred fracture, do not rub and move, so as not to aggravate the injury. Should be scarf, board and other tools to fix the fracture part, ask for help or alarm, as soon as possible to send to the hospital for treatment.
2, the car's anti-skid:
① anti-skid chain, in the tire outer layer of a layer of anti-skid chain, like the above said in the shoes set of anti-skid shoe covers. Relatively speaking, the price is more affordable.
② If the budget allows, you can change the snow tires, in order to ensure that your tires in the winter road surface to maintain good grip and handling performance, to ensure that you drive the safety of the journey, it is necessary to change to winter tires.
3, the bike's anti-skid:
Increase the contact area between the wheel and the ground can prevent skidding, reminding owners that it is best to choose thicker tires. The car body do not carry too much, too heavy items, riding process, remember not to brake sharply, otherwise it will make the wheels skidding, lose balance, snow day travel, or to slow riding is good. Try to avoid sharp turns, so that their center of gravity through the axle line and the ground to remain perpendicular to the road within the scope of the road permits the larger the turning radius the safer. Bicycle anti-skid increase the contact area between the wheel and the ground can prevent skidding, so it is best to choose thicker tires. The body of the car do not carry too much, too heavy items, riding process, remember not to brake sharply, otherwise it will make the wheels skidding, lose balance, snow day travel, or to slow riding is good. Try to avoid sharp turns, so that their center of gravity through the axle line and the ground to remain perpendicular to the road within the scope of the road permit the larger the turning radius the safer.
