Problems solved by technology

[0002] In the traditional dual power police system, only two batteries are connected in parallel to supply power to the vehicle and the police. In the parking state, the following situations may occur: the battery of the vehicle and the battery of the police are severely depleted due to long-term use of the police. This will affect the normal starting of the vehicle; the engine will charge the battery for a long time, resulting in a shortage of fuel for the vehicle, thus affecting the maneuvering distance of the police car
The above situations will affect the timely handling of the police situation.

Abstract

The invention discloses a dual-power supply police system for a police car and a control method thereof, which belong to the technical field of police control. The invention can intelligently judge the electric quantity of the battery of the whole vehicle and the battery of the police, and according to the fuel oil level, the running state of the engine, The operation mode of the police system is automatically selected in the driving state of the vehicle: when the battery loses power, the engine is automatically started to charge the battery of the vehicle and the battery of the police under the condition of ensuring the safety of the driver and the maneuverability of the vehicle. Stop the running of the engine; when the automatic charging conditions are not met, only use the police battery to supply power to the police, and at the same time automatically adjust the working mode of the police, and prolong the working time of the police as much as possible on the premise of ensuring the mobility of the vehicle. At the same time, the system also has fault self-diagnosis and reminder functions to prevent power system failure from affecting the maneuvering of police cars and the normal work of police equipment.

Description

technical field [0001] The invention belongs to the technical field of police equipment control, and in particular relates to a dual power supply police equipment system for a police car and a control method thereof. Background technique [0002] In the traditional dual power police system, only two batteries are connected in parallel to supply power to the vehicle and the police. In the parking state, the following situations may occur: the battery of the vehicle and the battery of the police are severely depleted due to long-term use of the police. Thereby affecting the normal starting of the vehicle; the engine charges the battery for a long time, resulting in a shortage of fuel for the vehicle, thereby affecting the maneuvering distance of the police car. The above situations will affect the timely handling of the police situation. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to provide a dual-power police system...
