Further, the liquid level sensor and temperature sensor are passive sensor.
The beneficial effects of the utility model are：Auto-Sensing Mode of this parking monitoring scheme based on whole vehicle controller, by
The storage battery power supply of vehicle, is detected vehicle with former fare road and module timing, can be in time with failure pinpointing the problems
Report and notify administrative staff's process problem；Except the on-line monitoring device for uploading fault message, the utility model does not increase
New module, changes former fare road small, the former car device completion monitoring of dependence, simple and reliable；And taken by vehicle battery
Electricity, due to can just charge in time for storage battery in vehicle day-to-day operation, as long as so vehicle normal operation does not just have to worry this reality
With new the problem of failing because of storage battery power shortage.
The utility model is also periodically powered for battery management system, when realizing parking to the high-pressure system of new energy vehicle into
Row monitoring.
The utility model also finds that vehicle is soaked in time by the liquid level sensor and temperature sensor that are arranged on vehicle
With the emergency case such as high-pressure system abnormal high temperature, wake up entire car controller and on-line monitoring device in time, in time by situation and therefore
Barrier reports, and notifies administrative staff to come to check and handle, and ensures vehicle before use safe and reliable.
Brief description of the drawings
Fig. 1 is vehicle monitoring system structure chart.
Embodiment
The utility model is described in more detail below in conjunction with the accompanying drawings.
A kind of vehicle monitoring system as shown in Figure 1, including on-line monitoring device supply relay (J1), battery management system
System supply relay (J2), liquid level sensor (SW1), temperature sensor (TC1).Entire car controller is powered by storage battery, and is had
Dormancy and arousal function, on-line monitoring device pass through power cord, on-line monitoring device supply relay (J1) and vehicle battery
Connection, the battery management system are connected by power cord, battery management system supply relay (J2) with vehicle battery, institute
State entire car controller and pass through control line and on-line monitoring device supply relay (J1), battery management system supply relay (J2)
Coil be connected, the entire car controller is connected with on-line monitoring device by monitoring CAN bus, and the on-line monitoring device leads to
Cross satellite with cloud server to be connected, the cloud server is connected by mobile network with terminal device, the terminal device
Can be the computer of management office or the mobile phone etc. of administrative staff, the entire car controller is paddled with being arranged on vehicle highest
The liquid level sensor (SW1) of position, the temperature sensor (TC1) being arranged near power battery are connected by signal wire.Temperature
Sensor (TC1) can be multiple in the position setting for high temperature abnormality easily occur, as power battery box everywhere, power line are each
Place etc., the position and quantity, the utility model that actual temp sensor is set do not limit.
Liquid level sensor (SW1) and temperature sensor (TC1) employed in the present embodiment, are all passive sensor, adopt
It can simplify circuit with passive sensor and save electric energy.
Relay is employed in the present embodiment as on-line monitoring device and the power switch of battery management system, equally
, as other embodiment, other controllable switching devices can also be used as respective switch, such as transistor circuit.
A kind of monitoring method of vehicle monitoring system of the utility model, specifically includes following steps：
1) after vehicle parking shuts down, vehicle power-off, entire car controller enters dormancy shape under the control from dormancy chip
State, quiescent current are less than 1mA；
2) entire car controller timing wake-up, specific time interval can be set as needed；
3) after entire car controller is waken up, control on-line monitoring device supply relay (J1), battery management system power supply
Relay (J2) closes, and is that on-line monitoring device and battery management system are powered, while entire car controller carries out vehicle self-test, complete
Into the comprehensive monitoring of vehicle high and low pressure system, if no abnormal, entire car controller disconnects on-line monitoring device power supply relay
Device (J1), battery management system supply relay (J2), and reenter resting state；
If 4) entire car controller monitors exception or failure, corresponding failure code is generated；On-line monitoring device is after the power-up
Entire car controller is scanned, after scanning to error code, corresponding error code is uploaded into cloud server by satellite, institute
State cloud server the error code and corresponding fault car be associated archive and establish database, and by the error code with short message or

5) entire car controller disconnects on-line monitoring device supply relay (J1), battery management system supply relay
(J2), and resting state is reentered.
In vehicle shutdown is parked, if vehicle meets with water logging, water level, which is constantly increased to vehicle high and low pressure system, soaked wind
When dangerous, then liquid level sensor (SW1) closure can be triggered, is waken up entire car controller after liquid level sensor (SW1) closure, vehicle control
Device closure on-line monitoring device supply relay (J1) processed and battery management system supply relay (J2), and carry out full car certainly
Inspection, if monitoring exception or failure, generates corresponding failure code, and upload corresponding error code and soaked warning；If do not monitor
Any exception or failure, then only upload soaked warning, the method for uploading is with timing wake-up monitoring step 4) in method for uploading
Identical, details are not described herein.
Parked in vehicle shutdown, if power cell of vehicle or other occurred by the Temperature Monitoring of HV Apparatus of temperature monitoring it is different
Often, as temperature anomaly increases to over the activation threshold value of default temperature sensor (TC1), then temperature sensor (TC1) closes, and
Wake up entire car controller, entire car controller closure on-line monitoring device supply relay (J1) and battery management system power supply relay
Device (J2), and carry out full car self-test, if monitoring exception or failure, generates corresponding failure code, and upload corresponding error code and
Overheat warning；If not monitoring any exception or failure, overheat warning is only uploaded, the method for uploading is monitored with timing wake-up
Method for uploading in step 4) is identical, and details are not described herein.
After vehicle is soaked or localized hyperthermia causes to upload corresponding warning, entire car controller can stay awake for, every
Carry out repetition of alarms every certain time, until service personnel be turned off manually or it is corresponding it is soaked or high temperature it is abnormal release, vehicle control
Device processed disconnects on-line monitoring device supply relay (J1), battery management system supply relay (J2) again, and reenters not
Dormancy state.
In recent years, since China city is fast-developing on a large scale, sewerage system often lags behind the speed of urban sprawl
Degree, often there is the situation of water logging after the rain in Some City location, and vehicle is particular with the new energy vehicle of high-pressure system
After soaked such as cannot discovery in time processing, it will cause the even more serious accident of vehicle damage；The utility model is for car
The abnormal conditions such as soaked or abnormal high temperature, can make a response in time, and notify party to come to handle, can to failure and
When handle, and effectively avoid property loss.
