Embodiment
The invention will be further described below in conjunction with drawings and Examples.
The invention provides the method and apparatus of a kind of electric-control motor remote monitoring, diagnosis and control, comprise vehicle GPS remote diagnosis and control terminal, remote monitoring software etc.Electronic control engine GPS (Global Position System) remote diagnosis of the present invention and control are based on GPS (Global Positioning System (GPS)), GPRS (global digital mobile communication network) and GIS (geographical information platform and data processing technique) and vehicle GPS remote diagnosis and control terminal and electric-control motor ECU and carry out that on the basis that CAN communicates by letter integration and development forms, by mobile car load there not being monitoring such as real time position under region, the no space constraint condition, engine control information, oil consumption.
The GPS long distance control system mainly is made up of vehicle GPS remote diagnosis and control terminal (hereinafter to be referred as car-mounted terminal) and Surveillance center's two parts.Described vehicle GPS remote diagnosis and control terminal are encapsulated in the housing, by the GPS receiver, and the GSM/GPRS transceiver module, the CAN communication module, main control module and various peripheral hardware are formed.The GPRS antenna is given prominence to housing, gps antenna extension case.The position (longitude, latitude, highly) that the positioning signal that the GPS receiver receives satellite calculates self sends to main control module and storage with certain frequency; The CAN communication module can realize communicating by letter of vehicle GPS remote diagnosis and control terminal and Engine ECU, and contents such as engine control information, engine failure, oil consumption send to the main control module with the form of message; The GSM/GPRS module is responsible for wireless transmitting-receiving transmission.By above process, system can realize that position of remote vehicle request, the inquiry of vehicle operating track, engine control information inquiry, vehicle operation status inquiry, vehicle remote fault diagnosis, vehicle accumulation oil consumption inquiry, vehicle remote control, vehicle use functions such as zone setting.
As shown in Figure 1, the communication mode of car-mounted terminal and Surveillance center adopts cordless communication network GSM/GPRS.Transmitting terminal adds with data that destination address is encoded according to the particular communication agreement and sends to Surveillance center.Surveillance center is decomposed into information such as discernible vehicle longitude and latitude, state after receiving and decoding with corresponding communications protocol equally after the information.Equally, Surveillance center also can start order to car-mounted terminal, as: forced idling, request failure code, running region setting etc.Surveillance center can carry out position, running status etc. to vehicle and monitor, and also can carry out the long-range pressure parking of engine, the control of long-range pressure limit oil.Engine is system's meeting self check GPS equipment running status when starting, if the destroyed work of GPS equipment is undesired, engine can't start.If GPS equipment is destroyed in operational process, engine will be by limit oil, and Surveillance center also can long-rangely control engine simultaneously.
Engine ECU and vehicle GPS remote diagnosis and control terminal are by the CAN bus communication, and communication protocol is SAE-J1939.The message that Engine ECU sends by vehicle GPS remote diagnosis and control terminal determines whether GPS work is normal, and messages such as the engine condition that vehicle GPS remote diagnosis and control terminal send ECU, failure code send it back Surveillance center by the mobile network.
In native system, Surveillance center can be by the long-range Engine ECU data that read of GPS, the data that ECU sends (CAN message) comprise sensor information and the failure code that sends with the forms of broadcasting, need send the total fuel consumption information of engine of request message, as shown in Figure 2.Surveillance center can long-rangely control engine, and after sending control command on the monitor terminal, after about six seconds, engine enters slave mode.Can control engine slope row or force parking and the operation area setting, as shown in Figure 3.
The present invention has adopted a design concept to the control of electric-control motor integrated diagnosis, and its main thought is based on the GPRS cordless communication network, car load CAN communication network can realize that long-range vehicle location request to electric-control motor, the inquiry of vehicle operating track, engine control information inquiry, vehicle operation status inquiry, vehicle remote fault diagnosis, vehicle accumulation oil consumption inquiry, vehicle remote control, vehicle use functions such as zone setting.These functions can effectively help bank to reduce car and borrow risk, help the user better fleet to be managed, and help automobile vendor better the user to be served.
The present invention is based on radio communication and car load CAN network, on electric-control motor, have good versatility.Engine ECU and GPS remote diagnosis and control terminal are by the CAN bus communication, and communication protocol is SAE-J1939, realize the engine control information inquiry, as current water temperature, current rotating speed etc.
Surveillance center's realization vehicle remote control is that the CAN message is controlled engine slope row indirectly or pressure is stopped by controlling; Realizing that vehicle uses the zone to set, is by control CAN message, the use zone or the travel route of locking vehicle; Realize vehicle remote fault diagnosis, vehicle accumulation oil consumption inquiry, be by remote request Engine ECU related data, thereby realize this function.
The concrete function of native system is described below:
1, inquiry location
But remote inquiry vehicle location.
2, trace playback
But the remote inquiry vehicle is in two years all driving traces recently.
3, engine information, failure code, accumulation oil consumption request
4, vehicle remote slope row control
Can control engine slope row or pressure parking.
5, the Vehicle Driving Cycle zone is set
Can use the zone to set to vehicle, after vehicle rolled setting regions away from, vehicle carries out the slope row.
6, route or travel by vehicle is set
Can carry out travel route to vehicle and set, after vehicle departed from travel route, vehicle carried out the slope row.
These functions have following several major advantage:
1, prevents that malice owes to borrow
Along with the reform of fuel oil tax, cancelled road toll, the car load dealer can not control user's repaying by original bill of road toll that relies on, and presses for vehicle is tightened control, to reduce the risk that malice is escaped to borrow.GPS remote diagnosis and control system can realize functions such as position of remote vehicle request, the inquiry of vehicle operating track, vehicle remote control, can effectively reduce credit risk.
2, fleet management needs
Along with the development of industries such as logistics passenger traffic, the Fleet size of part enterprise is increasing, and the owner of vehicle has occurred separating with the user.For the needs to fleet management, these enterprises need more effective means that institute's linchpin vehicle is monitored and managed, and can carry out remote monitoring to vehicle location, use oil consumption etc. by the GPS function.Also there is similar demand in administrative authoritys such as public security, traffic, environmental sanitation, postal service.
3, better after sale service
Car load enterprise can monitor the operating position of selling vehicle, is convenient to carry out the follow-up service of vehicle, as services such as remote diagnosis, emergency relief are provided.
