Step into 2020 soon, the situation of the epidemic has touched the hearts of hundreds of millions of people across the country. Although the Spring Festival holiday, but the automotive industry has long acted, whether it is the disposal of patients, sanitation and disinfection, or logistics and transportation, can see the busy back of countless car companies, although they are not in the front line of medical care, but the crystallization of their own wisdom and sweat for the front-line health care workers to provide the most effective and timely support for the protection.
Negative-pressure ambulance
The negative-pressure ambulance is undoubtedly one of the key demand materials for this epidemic. Due to its special attribute of transporting infectious patient groups, the negative pressure ambulance has higher requirements in design compared to ordinary ambulances, especially the medical cabin that can realize "negative pressure isolation", which can avoid cross-infection of doctors and patients as well as contamination of the external environment to prevent further spread of the epidemic. After starting the negative pressure device, can control the direction of air flow in the car, so that clean air from the medical warehouse above into the car, from the bottom of the discharge, the formation of directional airflow, and the formation of the external environment relative to the atmospheric low-pressure difference (the relative pressure of -30pa to -20pa between). The air exhaled by the patient is sucked into the device through the suction terminal and then discharged to the outside of the vehicle after disinfection, preventing the transmission of pollution, and also ensuring that the gas with infectious poisons will not circulate in the vehicle, and also avoiding secondary pollution. At the same time, in order to protect the driver's safety, the soundproof wall of the medical compartment is seamlessly welded to the body and filled with sealant, making the medical compartment completely independent from the front cockpit.
On this basis, if there are higher requirements for the protection capability of negative pressure ambulances, it is necessary to assemble a special isolation cabin as the second line of defense of the ambulance. This kind of stretcher based on the addition of sealing, negative pressure device isolation cabin for toxic gas environment and suspected or confirmed respiratory tract infectious disease isolation transportation. The isolation module also adopts the principle of positive and negative pressure, the positive pressure can effectively prevent the external toxic gases from entering the cabin, and the negative pressure principle can prevent the leakage of contaminated air inside the cabin. The high efficiency filtration canister makes the external toxic gas or internal polluted gas to be filtered efficiently to ensure that the filtered gas is clean.
In the process of fighting the epidemic, there are already many negative pressure ambulance manufacturers such as SAIC Datsun, Brilliance Group, JAC Commercial Vehicles, etc. responding to the call to work overtime to resume production during holidays, and contributing to the winning of the epidemic prevention and control blocking war with practical actions in the critical period of the epidemic.
Totally enclosed transport vehicle
In addition to the negative pressure ambulance to transport patients, in order to guarantee the timely and effective delivery of supplies during the epidemic, freight vehicles across the country also on the line. in mid-early February, due to the epidemic prevention and control needs, Baodi District, Tianjin City, in urgent need of a large number of disinfectant, but the relevant units responsible for the function of disinfectant Baodi District disinfectant delivery due to vehicle control can not be purchased and pick up, the relevant units, the relevant units are not able to purchase and pick up. Ltd.'s more than ten new energy vehicles were ordered to complete the delivery task on February 11th and February 14th in two parts. It is reported that the original bear "mobile recycling" task of the new energy transportation vehicle warehouse for the fully enclosed design, can protect the material in the rain and snow weather and epidemic infected areas of transportation safety.
Epidemic prevention and disinfection machinery vehicles
In order to prevent the spread of the epidemic, all over the world have increased the spraying disinfection operations to minimize the spread of the virus, and on February 7, Dongfeng urgently donated a batch of epidemic prevention and disinfection machinery to Xiangyang city in response to the actual needs of Xiangyang city. 74 sets of epidemic prevention and disinfection machinery were donated by Dongfeng on February 14, which will further alleviate the situation of insufficient machinery to help local epidemic prevention and disinfection. On February 14, Dongfeng donated 74 sets of anti-epidemic and disinfection machinery to Xiangyang City, which will further alleviate the shortage of local anti-epidemic machinery and help local health, sanitation and other departments to carry out full-coverage and dead-end spraying and disinfection actions. on February 18, Dongfeng donated anti-epidemic and disinfection machinery valued at more than 12 million yuan to Wuhan City and Shiyan City*** to support the local work of combating epidemics. As a result, Dongfeng, together with its enterprises, has donated more than 82 million yuan.
Winning the battle of epidemic prevention and control is an important part of material protection. As a new force on the battlefield of epidemic prevention and disinfection, this batch of epidemic prevention and disinfection machinery will quickly go to the forefront, and the local urban management and sanitation front of the "epidemic prevention pioneers" to work side by side to carry out full-coverage, no dead-end spray disinfection action, hand in hand with *** with the fight against the epidemic.
The epidemic coincided with the Spring Festival holiday, coupled with the special nature of the "man to man", so that people actually feel the bottleneck of manpower and unmanned industry contains a huge potential, and before most of the unmanned car in the huge amount of money to engage in research and development enterprises have really experienced the "army of thousands of days to use the army for a while! The unmanned vehicle enterprises have also truly realized the sense of mission of "keeping an army for a thousand days and using it for an hour". For a time, unmanned vehicles appeared in various key positions to combat the epidemic, effectively alleviating the pressure of the work of the infected areas, and become an indispensable and important role in the front line of the "war epidemic".
Jingdong unmanned delivery car
In the streets of Wuhan, people often see a lovely shape of the car shuttle in the heart of the epidemic, where attracted countless eyes, in fact, it is the Jingdong unmanned delivery car. After the outbreak of the epidemic, Jingdong began to look for more high-tech means to support Wuhan, and tried to use intelligent distribution in the core area of the epidemic outbreak. Since a large number of confirmed patients were gathered in Wuhan's Ninth Hospital, and there was also a large demand for supplies, the first delivery mission of Jingdong's unmanned delivery vehicles started from here.
It is reported that in order to safely and accurately deliver the supplies, Jingdong's intelligent unmanned vehicle collects a variety of high-tech, such as automation, computers, artificial intelligence, etc., which not only replaces the human eye to carry out 360-degree environmental monitoring, automatically avoids roadblocks and pedestrians, and immediately reacts to traffic lights when encountered, but also autonomously stops at the distribution point to send the pickup information to the user. Users, on the other hand, can pick up their goods in three ways: through face recognition, entering a pickup code, and clicking on a link to a mobile app.
5G Unmanned Vehicle Sharing-VAN
On February?4?, two 5G unmanned vehicles Sharing-VAN jointly built by Dongfeng and Huawei were sent to Wuhan's Xinguan Pneumonia Epidemic Prevention and Control Command, which will be allocated to relevant hospitals for the isolation of the sick area operations to protect the safety of front-line medical workers.
Initially released in the first half of 2019, the 5G unmanned vehicle measures 4,500/1,800/2,100mm and can accommodate four medical workers and two stretcher carriers at the same time, or allow up to six people to ride at the same time. It is built using the high-bandwidth and low-latency characteristics of 5G networks, and is equipped with four Radium God vehicle-grade CH32-line hybrid solid-state LiDARs, which can make accurate judgments on complex road conditions and sense the location of vehicles and people 100 meters away in 360°. In other words, it can safely and quickly transport people and materials in a complex hospital environment. It is reported that Sharing-VAN is developed by Dongfeng Motor in cooperation with Huawei, which is responsible for the development of vehicle systems and hardware and software, while Dongfeng Motor is responsible for technical guidance and project follow-up.
Snail Xiaobai, a driverless sweeper
Snail Xiaobai is a driverless sweeper developed by Baidu's Apollo eco-partner, Smartwalker. According to the plan, Zhi Xing Zhi will be equipped with 1-2 sets of unmanned cleaning and disinfecting vehicles/delivery vehicles for each of the 16 key patient admission hospitals across the country. Currently, the unmanned sweeping and disinfecting vehicles are already operating in hospital scenarios such as Huashan Hospital of Fudan University and Ear, Nose and Throat Hospital of Fudan University.
The weight of nearly 400 kilograms of the "little fat man" looks unimpressive, but is equipped with a variety of sensors such as laser radar, camera, ultrasonic radar, can realize the autonomous operation. Sweeper from manual operation, autonomy in the road surface to complete the sweeping, sprinkling, garbage collection and other work, 15 ° slope also go up, sweeping width of 100cm, removable dumping dust box capacity of 60L, cleaning area of 3,000 square meters per hour, full of electricity can be 6-8 hours of continuous work. The appearance of the snail white greatly improves the cleaning efficiency of the infected area, reduces the chance of infection, and also makes the cleaning more intelligent.
New Stoneware Unmanned Disinfection Vehicle
Another New Stoneware Unmanned Disinfection Vehicle based on Baidu's Apollo eco-platform is also on the front line to provide essential disinfection protection for people.
On Shanghai's Zhangjiang Artificial Intelligence Island, the popular little guy can be seen early every morning working hard to spray disinfectant for every road on the island. According to the staff, this small car can be loaded with 200 liters of disinfectant, in a simple debugging, will be able to open the self-propelled spray disinfection mode. The unmanned vehicle disinfection spraying range covers 3-5 meters, according to the speed of 5 kilometers per hour, about half an hour can be the island road full coverage, greatly improving the efficiency of disinfection.
In addition to disinfection, the unmanned vehicle can also be transformed into an "inspector", through the equipped sensory camera and voice broadcasting function on the violation of anti-epidemic norms of the behavior of the warning or remote monitoring, to remind the personnel to wear masks, less gathering. Under the premise of ensuring charging conditions, the unmanned vehicle can work 24 hours a day, night disinfection operations, but also synchronized security monitoring. At present, there have been several new stone unmanned vehicles sent to Wuhan, put into the epidemic prevention work.
