There are so many people in the world that different things happen every moment. There are accidents happening almost every day. The occurrence of various accidents requires the personnel who have the ability to handle the accident to arrive at the scene. The rescue time after an accident is every second, and it is urgent to arrive at the scene to rescue. So how can we get to the scene at the fastest time? At this time, it is necessary to use means of transport, and different work departments also have corresponding command vehicles. These command vehicles can move, so they are called mobile command vehicles. The structure of the mobile command vehicle is similar to that of other command vehicles, and the equipment in command vehicles for different accidents will also change. A mobile command vehicle is a vehicle that can be used to move commands in the field. Like other command vehicles, it can transmit information and images from the site to the command center. By gathering information at the scene, it is transmitted to superior leaders and follows the command of superiors. If the situation requires, you can also open video conferencing countermeasures. Doing so will help strengthen collaboration among various departments and improve the efficiency of accident handling. The mobile command vehicle also has the function of monitoring. Public security organizations can monitor each other's actions in real time when they crack down on criminals. This will help the public security organs seize the criminals, so as to make the society more stable. The mobile command vehicle adopts a combination of wireless and wired information networks, which complement each other and further improve the technology of the equipment. The use of mobile command vehicles has brought convenience to all departments. After receiving the accidents and locations, each department can quickly reach the scene through the driving command vehicle. At the same time, after arriving at the scene, relevant information and images can be collected and transmitted to the command center through the equipment. The personnel of the command center can provide suggestions for rescue. In recent years, accidents that occur on a daily basis in various parts of the world have been frightening, ranging from accidents such as car accidents and fires to crimes committed by international terrorist organizations. The occurrence of these things affects people's lives as well as social stability. The mobile command vehicle enables the staff to better handle the various accidents that happen on a daily basis.
German industrial standard: Deutsche industrie normung, its English name is German DIN standard battery, lets take the model number of 54434 battery as an example, which is described as follows:
1. If the model number starting with 5 indicates that the rated capacity of the battery is less than 100 AH. The beginning 6 indicates that the battery capacity is between 100Ah and 200Ah. Starting with 7 indicates that the rated capacity of the battery is greater than 200Ah. For example, the rated capacity of 54434 batteries is 44Ah. The rated capacity of the 61017MF battery is 110Ah. 70027 The rated capacity of the battery is 200Ah.
2. The two digits number behind the capacity indicate the battery size and group number.
3.MF indicates maintenance-free.
4. The American standard battery can also be expressed in this way :78-600,78 indicates the battery size group number,600 indicates that the cold start current is 600A.
Note: â‘ Cold start current (CCA): The minimum current in a particular sense that can be obtained under the conditions of -17.8C and -28.9C. This index relates the starting capacity of the battery to important variables such as engine displacement, compression ratio, temperature, starting time, technical status of the engine and electrical system, and the minimum service voltage for starting and ignition. It refers to the minimum current that a fully charged 12V battery can supply when its terminal voltage drops to 7.2V within 30s. The cold start rating gives the total current value.
(2) Reserve capacity (RC): the car in the charging system does not work, at night by battery ignition and provide minimum circuit load can run the approximate time, can be specifically expressed as: fully sufficient 12V battery, Under the condition of 25+2℃, the discharge time at 25A constant discharge until the terminal voltage of the battery drops to 10.5±0.05V.
