Unmanned vehicles, negative pressure vehicles, closed transport vehicles ... take stock of special vehicles on the front line of epidemic prevention.

Shortly after entering 2020, the epidemic has touched the hearts of hundreds of millions of people across the country. Although it is the Spring Festival holiday, the automobile industry has taken action. Whether it is patient treatment, sanitation and disinfection, or logistics and transportation, we can see the busy backs of countless automobile companies. Although they are not in the front line of medical care, they provide the most effective and timely support for the front-line medical staff with their wisdom and sweat.

negative pressure ambulance

There is no doubt that negative pressure ambulance is one of the key materials needed to deal with the epidemic. Because of the particularity of transporting infectious patients, negative pressure ambulances have higher requirements in design than ordinary ambulances, especially the medical cabin that can realize "negative pressure isolation", which can avoid cross-infection between doctors and patients and pollution to the external environment and prevent the epidemic from spreading further. After the negative pressure device is started, the direction of air flow in the vehicle can be controlled, so that clean air can enter the vehicle from above the medical warehouse and be discharged from below, forming a directional air flow, forming a low atmospheric pressure difference (relative pressure is between-30pa and-20pa) relative to the external environment. The air exhaled by the patient passes through the inhalation device of the inhalation terminal, and is discharged from the car after disinfection, so as to prevent pollution, and at the same time, the gas with infectious virus is not circulated in the car, and secondary pollution is also avoided. At the same time, in order to protect the driver's safety, the sound insulation wall of the medical cabin is welded seamlessly with the car body, and sealant is added to make the medical cabin completely independent from the front cockpit.

On this basis, if there is a higher requirement for the protective ability of negative pressure ambulance, it is necessary to assemble a special carriage as the second line of defense for ambulance. This isolation cabin with sealed negative pressure device on the basis of stretcher is suitable for isolation and transportation of patients suspected or diagnosed with respiratory infectious diseases in toxic gas environment. The compartment also adopts the principle of positive and negative pressure. Positive pressure can effectively prevent toxic gases from entering the cabin, and negative pressure principle can prevent polluted air from leaking out. The high-efficiency filter tank can efficiently filter external toxic gas or internal polluted gas to ensure the cleanness of the filtered gas.

In the process of fighting the epidemic, many negative pressure ambulance manufacturers, such as SAIC Chase, Brilliance Group and Jianghuai Commercial Vehicle, responded to the call to work overtime on holidays and resume production. In the critical period of fighting the epidemic, practical actions have contributed to winning the prevention and control of the epidemic.

Fully enclosed transport vehicle

In addition to negative-pressure ambulances transporting patients, freight vehicles from all over the country have also gone into battle to ensure the timely and effective delivery of materials during the epidemic. In early February, due to the need of epidemic prevention and control, Baodi District of Tianjin urgently needed a large number of disinfectant, but the relevant units responsible for disinfectant distribution in Baodi District were unable to purchase and pick up the goods due to vehicle control. More than 10 sub-new energy vehicles sold by Tianjin Pickup Technology Co., Ltd. were ordered to deliver the goods twice, and the time was February 1 1 and February 14 respectively. It is reported that the warehouse of new energy transport vehicles, which originally undertook the task of "mobile recycling", is completely closed, which can ensure the transportation safety of rain and snow weather and materials in epidemic areas.

Epidemic prevention and disinfection mechanical vehicle

In order to prevent the spread of the epidemic, all localities have stepped up spraying and disinfection actions to minimize the spread of the virus. On February 7th, Dongfeng Company urgently donated a batch of epidemic prevention and disinfection machinery to Xiangyang according to the actual demand. On February 14, Dongfeng Company donated 74 epidemic prevention and disinfection machinery to Xiangyang City, which will further alleviate the shortage of local epidemic prevention machinery and help local health and sanitation departments to carry out full coverage and no dead angle spraying and disinfection operations. On February 18, Dongfeng Company donated epidemic prevention and disinfection machinery worth120,000 yuan to Wuhan and Shiyan to support local epidemic prevention work. As a result, Dongfeng Company and its enterprises donated more than 82 million yuan.

Material support is an important part of winning the epidemic prevention and control war. As a new force in the field of epidemic prevention and disinfection, this batch of epidemic prevention and disinfection machinery will quickly go to the forefront, fight side by side with the "epidemic prevention pioneer" of the local urban management and sanitation front, carry out the spraying and disinfection operation with full coverage and no dead angle, and join hands with * * * to fight the epidemic.

The epidemic coincided with the Spring Festival holiday, and the particularity of "human-to-human transmission" made people really feel the bottleneck of manpower and the great potential of the driverless industry. Previously, most unmanned vehicle companies that invested heavily in R&D have truly realized the mission of "training for a thousand days and taking a period of time". For a time, unmanned vehicles appeared in various key positions to fight the epidemic, effectively alleviating the work pressure in the epidemic area and becoming an indispensable role in the front line of "war and epidemic".

JD.COM unmanned vehicle

On the streets of Wuhan, people often see lovely cars shuttling through the core area of the epidemic, attracting countless eyes. In fact, it is an unmanned vehicle in JD.COM. After the outbreak, JD.COM began to look for more high-tech means to support Wuhan, and tried to use intelligent distribution in the core area of the epidemic. Because there are a large number of confirmed patients in Wuhan No.9 Hospital and there is a large demand for materials, the first delivery task of JD.COM unmanned delivery vehicle begins here.

According to reports, in order to transport materials safely and accurately, Jingdong Intelligent Unmanned Vehicle integrates a variety of high and new technologies such as automation, computer and artificial intelligence, which can not only replace human eyes for 360-degree environmental monitoring, but also automatically avoid roadblocks and pedestrians and react immediately when encountering traffic lights. You can also stop at the distribution point independently and send the pickup information to the user. Users can pick up the goods by face recognition, entering the delivery code and clicking the mobile APP link.

5G unmanned vehicle sharing-truck

2? Month? 4? On, two 5G unmanned vehicles, Sharing-VAN, jointly built by Dongfeng and Huawei, were sent to the epidemic prevention and control headquarters in COVID-19, Wuhan, and the headquarters will be assigned to relevant hospitals to isolate ward operations and protect the safety of frontline medical workers.

This 5G unmanned vehicle was first released in the first half of 20 19. Its body size is 4500/ 1800/2 100mm, which can accommodate four medical staff and two stretchers at the same time, or allow six people to ride at the same time. It uses the high bandwidth and low delay characteristics of 5G network, and is equipped with four laser-grade CH32-line hybrid solid-state laser radars, which can accurately judge the complex road conditions and perceive the positions of vehicles and people 360 degrees away from 100 meters. In other words, it can transport personnel and materials safely and quickly in a hospital environment with complex personnel. It is reported that Sharing-VAN is jointly developed by Dongfeng Motor and Huawei. Huawei is responsible for in-vehicle system and software and hardware development, while Dongfeng Motor is responsible for technical guidance and project follow-up.

Unmanned sweeper snail white

Woxiaobai is an unmanned sweeper developed by Baidu Apollo ecological partner Zhixing. According to the plan, Zhixingzhe will equip 1-2 unmanned cleaning and disinfection vehicles/delivery vehicles for the national 16 key patient hospitals. At present, unmanned cleaning and disinfection vehicles have been operated in Huashan Hospital affiliated to Fudan University, Fudan University Otolaryngology Hospital and other hospitals.

This "chubby pier" weighing nearly 400 kilograms is ugly in appearance, but it is equipped with various sensors such as laser radar, camera and ultrasonic radar, which can realize autonomous operation. Without manual operation, the sweeper can independently clean, sprinkle water and collect road garbage, and walk at a slope of 15, with a cleaning width of 100cm, a detachable ash dump box capacity of 60L, and a cleaning area of 3,000 square meters per hour. It can work continuously for 6-8 hours after being fully charged. The appearance of snail white has greatly improved the cleaning efficiency of epidemic areas, reduced the probability of infection and made cleaning more intelligent.

Neolithic unmanned disinfection vehicle

Another Neolithic unmanned disinfection vehicle based on Baidu Apollo ecological platform also provides people with necessary disinfection protection in the first line.

On the artificial intelligence island in Zhangjiang, Shanghai, every morning, people can see this little guy trying to spray disinfectant on every road on the island. According to the staff, this car can be loaded with 200 liters of disinfectant. After simple debugging, the self-propelled spray disinfection mode can be started. The disinfection and spraying range of unmanned vehicles covers 3-5 meters. According to the speed of 5 kilometers per hour, the roads on the island can be completely covered in about half an hour, which greatly improves the disinfection efficiency.

In addition to undertaking disinfection work, the Neolithic unmanned vehicle can also become an "inspector". Through the equipped perceptual camera and voice broadcast function, it can provide early warning or remote monitoring for violations of epidemic prevention norms, reminding personnel to wear masks and gather less. Under the premise of ensuring the charging conditions, the unmanned vehicle can work 24 hours a day, and the safety monitoring can also be carried out simultaneously when performing disinfection work at night. At present, several Neolithic unmanned vehicles have been sent to Wuhan for epidemic prevention work.
