The DCDC controller connects ignition switch.
The video monitoring equipment is equipped with the storage unit for caching picture or video information, the vehicle-mounted lead acid storage battery
Power end of the pond through additional equipment supply relay connection additional equipment.
A kind of control method based on the mobile monitoring device:
When electric vehicle ignition switch is on state, DCDC controller is converted to the high-voltage electricity of vehicle mounted dynamic battery
12V low pressure is additional equipment power supply；
When electric vehicle ignition switch is in OFF state, vehicle-mounted lead-acid accumulator is additional equipment power supply.
When electric vehicle ignition switch is in OFF state, vehicle communications device timing wake-up BCM obtains vehicle-mounted lead acid storage battery
The voltage value in pond, when detecting voltage value lower than given threshold, then BCM drives entire car controller to start DCDC controller, utilizes
Vehicle mounted dynamic battery is vehicle-mounted lead acid battery charge.
When detecting voltage value lower than given threshold, first entire car controller is driven to carry out high-pressure system detection, if high pressure
System detection fault-free restarts DCDC controller.
Using vehicle mounted dynamic battery be vehicle-mounted lead acid battery charge when, when charging between be more than given threshold after, terminate
Charging.
The present invention is capable of providing a stabilization and works long hours, and conducive to the vehicle-mounted monitoring platform of maintenance, improves electric vehicle
The reliability used, to adapt to the application of special car new energy.
Detailed description of the invention
The content of width attached drawing every in description of the invention expression is briefly described below:
Fig. 1 is the hardware block diagram of the mobile monitoring device based on pure electric vehicle；
Fig. 2 is that the intelligence of the mobile monitoring device based on pure electric vehicle mends method for electrically schematic diagram.
Specific embodiment
As shown in Figure 1, 2, it includes: additional equipment-video monitoring equipment that mobile monitoring device and intelligence, which are mended in method for electrically,；Add
Install standby-mobile communication equipment, backstage, additional equipment supply relay, vehicle-mounted lead-acid accumulator (12V), DCDC controller, point
Fiery switch relay, ignition switch, vehicle mounted dynamic battery, VCU (entire car controller), BCM (car body controller), T-Box are (vehicle-mounted
Communication device).
Monitoring device (acquisition+forwarding) is packed into pure electric vehicle, i.e., on pure electric vehicle, installs video monitoring additional and sets
It is standby, on pure electric vehicle, install wireless telecommunications system additional, video monitoring equipment passes through wireless telecommunications system in real time, will be real-time
Monitoring image is transferred to backstage, and video transfer signal of the background monitoring center real-time reception from front, Vehicular video monitoring is set
It is standby to have certain local storage space, can be with cache image when wireless telecommunications system is problematic, and restore in wireless telecommunications
When, reissue data.
Video monitoring equipment or wireless telecommunications system pass through interior 12V low-voltage electric system power supply, interior low pressure (12V)
Routine can be passed through when a small amount of equipment is needed using routine 220V Alternating Current Power Supply using lead-acid accumulator+high voltage power battery power supply
Inverter, 12V DC electricity is converted into 220V Alternating Current Power Supply
When operator on duty onboard when, vehicle is in IGN ON state, using normal running mode, high-pressure system without reason
In the case where barrier, high-pressure system is worked normally, and by DCDC controller, on-board high-voltage is converted to 12V low pressure, is low tension
Device system power supply, while powering for video monitoring equipment and wireless telecommunications system；
When operator on duty leaves vehicle, vehicle normally can be entered into IGN OFF state, locking and vehicle of setting up defences,
Vehicle enters dormant state, vehicle-mounted video monitoring device and wireless telecommunications system, is directly powered by 12V low tension battery, protects
Power supply state is held, vehicle-mounted A-battery is in continuous drain state.
In unattended duty, vehicle operating status is as follows
Vehicle communications device timing (timing can be set) wakes up BCM and carries out the detection of battery voltage value；As BCM is detected
When too low to cell voltage, BCM car body controller issues intelligence and mends electricity request, and BCM car body controller issues intelligence and mends electricity work
Instruction；After the intelligence that VCU entire car controller receives the sending of BCM car body controller mends electricity request, high-pressure system detection is carried out,
After VCU entire car controller detects vehicle high-pressure system no problem, starts DCDC controller, on-board high-voltage is converted into 12V low pressure
Direct current charges to vehicle-mounted low tension battery, and VCU entire car controller intelligently mends electricity condition to BCM car body controller report；BCM vehicle
Body controller controls relay-operating time, and the detection benefit electricity time is electric more than intelligence benefit after threshold value, is terminated；It completes intelligence and mends electricity.
The mobile monitoring system based on pure electric car is benefited from country and is widelyd popularize to new energy vehicle, makes new energy
The single vehicle cost and vehicle performance of source vehicle have promotion at full speed, meanwhile, with the optimization of new energy vehicle control strategy,
In vehicle unattended duty, the safe and reliable of vehicle and the continuous and effective to vehicle low-voltage electrical apparatus and monitoring system also can guarantee.
In addition, required according to national legislation, each new energy vehicle in producer and national platform, can know its presence and
Vehicle position information is based on above-mentioned characteristic, installs corresponding monitoring device additional, and can persistently supply to video monitoring and transmission device
Electricity, can be connect in security vehicle patrol, 110 deal with emergencies and dangerous situations, deal with contingencies, natural calamity accident when have important work
With being a kind of novel, practical mobile monitoring system based on pure electric car.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing
