Problems solved by technology

At present, there are many problems in the main power switch 12. One, the manual power main switch or the electromagnetic power main switch is easily forgotten by the driver, causing the storage battery 14 to lose power; And the above switch cannot be turned off
When the battery 14 is further discharged, the engine 16 of the vehicle cannot be started, and restarting requires an external battery 14, or temporary charging and other complicated work

Embodiment 1

[0037] Such as figure 2 As shown, the method for controlling the main power switch of an engineering vehicle according to an embodiment of the present invention includes:

[0038] Step 10: receiving an instruction from an external terminal to turn off or turn on the main power switch;

[0039] In engineering vehicles, there are generally main power switches, but mechanical switches and electromagnetic switches are mainly used. Both switches need to be manually operated by the driver, and even can only be manually operated in the cab, which makes the driver busy. It is easy to forget to turn off the main switch at the engineering site, which causes the circuit to remain connected. After a certain period of time, it will cause the battery to lose power. Increase labor cost, time cost and reduce work efficiency. And due to the power supply requirements of the whole vehicle, some electrical equipment needs to be connected to normal power. The main power switch in the prior art ...

Embodiment 2

[0047] Such as image 3 As shown, the method for controlling the main power switch of an engineering vehicle according to another embodiment of the present invention includes:

[0048] Step 20: When the main power switch is turned on and the engine of the vehicle is turned off, detect the remaining power of the battery of the vehicle;

[0049] When the battery of the vehicle is too low, it will cause the vehicle to fail to start. Therefore, by detecting the remaining power of the battery of the vehicle, it can be found in time whether the battery is too low, so as to take protective measures to reduce the possibility of the vehicle being unable to start, so as to improve work efficiency. Efficiency and cost savings.

[0050] In addition, when the engine is started and the on-board generator generates electricity, the battery can be charged immediately, so there is no problem of remaining power. Therefore, it is only necessary to detect the remaining power of the vehicle's bat...

Embodiment 3

[0060] Such as Figure 4 As shown, on the basis of Embodiment 2, the method for controlling the main power switch of an engineering vehicle according to an embodiment of the present invention includes:

[0061] Step 30: When the main power switch is on and the engine is off, detect the control distance between the external terminal and the vehicle;

[0062] After the engine is turned off, the driver will leave the car to handle other affairs if there is no special situation, so the distance between the driver and the vehicle will become farther and farther. If it is a mobile external terminal, it will also leave the vehicle with the driver's carrying It is getting farther and farther away; therefore, by detecting the control distance between the external terminal and the vehicle, the distance between the driver and the vehicle can be judged, and then judge whether the driver has left the vehicle according to the distance between the driver and the vehicle, and whether he has f...

Abstract

The invention provides a control method and device of a power supply total switch of a vehicle. The control method of the power supply total switch of the vehicle comprises the steps that an instruction, emitted by an external terminal, for turning off or turning on the power supply total switch is received; and the power supply total switch is turned off or turned on according to the instructionso as to cut off or feed through an external power supply circuit of a storage battery of the vehicle. According to the technical scheme, remote wireless control and automatic control of the power supply total switch of the vehicle are achieved, the possibility of lack of electricity of the storage battery of the vehicle is reduced, then the possibility that the vehicle cannot be started due to lack of electricity of the storage battery is reduced, the working efficiency is improved, in an emergency situation, the power supply total switch can further be turned off through the external terminal, supply of power of the vehicle is cut off, and safety of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a control method and a control device for a main power switch of a vehicle. Background technique [0002] According to the requirements of GB 7258 "Technical Conditions for Motor Vehicle Operation Safety": special school buses should be equipped with a main power switch, and passenger cars with a length of 6 meters or more should be equipped with an electromagnetic main power switch; passenger cars with a length of 6 meters or more should also be equipped with a power switch that can cut off the battery. Manual mechanical disconnect switches connected to all circuits. At the same time, considering the battery loss of the whole vehicle, etc., the general vehicle is equipped with a main power switch. [0003] Such as figure 1 As shown, in the prior art, the general design is to install a main power switch 12 at the output end of the storage battery 14. The main power swit...
