Abstract
The invention relates to a remote monitoring terminal for an electric automobile, and aims to provide a low-cost, low-power consumption, controller-area-network(CAN)-bus-based microcomputer remote monitoring terminal for an electric automobile, so the extensive use of the device is possible. The remote monitoring terminal comprises a power supply module, a central processing unit (CPU) module, and a CAN bus transceiver, a global position system (GPS) module, a global system for mobile communication (GSM) communication module, and a data storage module connected with the CPU module; and the CAN bus transceiver is connected with a storage battery, a motor and an electric control system of the electric automobile via a CAN network of the electric automobile. By a CAN bus technology and an Advanced RISC Machine (ARM)7 singlechip, the cost of the whole device is lower, the power consumption is lower, the performance is more stable, and the volume is smaller, so the device is suitable for extensive use.
Description
Technical field
The present invention relates to a kind of automobile remote monitoring equipment, in particular, the invention relates to the long-distance monitorng device of electric automobile.
Background technology
Along with country vigorously supports the development of electric automobile, electric automobile starts to enter a large amount of operational phase, as pure electric automobile (all by battery as power source), hybrid vehicle (providing power to automobile by battery together with other energy).But it is all in a developing stage, even if also often there is many failure problems in the electric automobile of going into operation, at this moment the working condition of Real-time Collection and monitoring vehicle, wireless remote collects the service data of electric automobile kernel component, especially three large kernel components: battery, motor, electric-control system, just become particularly important to the performance of examination electric automobile.Patent Office of the People's Republic of China has announced a CN201004627Y document on January 9th, 2008, name is called electric automobile information gathering and radio transmitting device, and this device comprises: the microcomputer motherboard of Based PC 104 bus, 512M CF card, 128M memory bar, CAN communication plate, gsm communication module, GPS module, DC/DC module, I/O interface, SIM card, keyboard.Main application comprises: by the information such as voltage, electric current of the every block battery of CAN collection; The locating information that Real-time Obtaining vehicle travels; Periodically locating information and battery information are preserved in a database; User is by the data in USB flash disk automatically downloading data storehouse; Radio communication is carried out with GSM short message or GPRS mode and Surveillance center; Electronic chart shows.This device Based PC 104 bus, be equivalent to PC as process information center, cost is high, and power consumption is large, is unfavorable for a large amount of uses in electric automobile field.
Summary of the invention
The invention solves the problem that original cost is high, power consumption is large, provide a kind of low cost, low-power consumption, based on the microcomputer remote control terminal of electric automobile of CAN, make a large amount of uses of this device become possibility.
The technical solution adopted for the present invention to solve the technical problems is: a kind of remote control terminal of electric automobile, comprises power module, CPU module and the CAN transceiver be connected with CPU module, GPS module, GSM communication module, data memory module; CAN transceiver is connected with accumulator of electric car, motor, electric-control system by the CAN network of electric automobile.CAN protocol meets international SAEJ1939 CAN standard, supports standard frame and expansion Frame Protocol form simultaneously.Adopt CAN to gather electric automobile data, only need a CAN line just can gather sensing datas all on automobile, comprise accumulator of electric car data, motor data, electric-control system data, engine data, instrumented data etc.
The relevant information of accumulator of electric car, motor, electric-control system is delivered to CPU module by the CAN network of electric automobile by CAN transceiver.CPU module by these information and the positional information that received by GPS module by analysis with process after, be wirelessly sent to Surveillance center by GSM communication module on the one hand, preserved by data memory module on the one hand, can retransmit time bad with convenient wireless signal.Information that GSM communication module will send adopts data subpackage treatment mechanism, effectively solves wireless network when carrying out large transfer of data, loss of data and a difficult problem of makeing mistakes.
As preferably, the single-chip microcomputer of described CPU module to be model be ARM7.The single-chip microcomputer price of this model is low, power consumption is little, stable performance, is conducive to a large amount of use.
As preferably, described CAN transceiver is also connected with the engine of electric automobile by automotive CAN network.When electric automobile adopts hybrid power, also the relevant information of automobile engine can be sent to Surveillance center.
As preferably, described CAN transceiver is also connected with the instrument of electric automobile by automotive CAN network.As required, also the relevant information of the various instrument of electric automobile can be sent to Surveillance center.
The invention has the beneficial effects as follows: adopt CAN technology and ARM7 single-chip microcomputer, make that whole installation cost is lower, power consumption is less, performance is more stable, volume is less, be conducive to a large amount of use.
Accompanying drawing explanation
Fig. 1 is a kind of electrical principle block diagram of the present invention.
Embodiment
Below by specific embodiment, and by reference to the accompanying drawings technical scheme of the present invention is described in further detail.
Embodiment:
A kind of remote control terminal of electric automobile, see Fig. 1, comprises the single-chip microcomputer of ARM7, and the CAN transceiver, GPS module, GSM communication module, the data memory module that are connected with the single-chip microcomputer of ARM7; Power module is above each module for power supply.
The relevant information of accumulator of electric car, motor, electric-control system, engine, instrument is delivered to the single-chip microcomputer of ARM7 by CAN transceiver by the CAN network of electric automobile.GPS module is by the single-chip microcomputer of the traveling-position signal transmission of automobile to ARM7.Received information carries out analyzing, processing by the single-chip microcomputer of ARM7, and result is stored in data memory module; When cordless communication network cannot use, data can not be lost; After cordless communication network recovers, again data are sent to GSM communication module.Under normal circumstances, result is directly sent to GSM communication module by the single-chip microcomputer of ARM7.GSM communication module is by these data acquisitions subpackage treatment mechanism, size is divided into multiple small data packets according to the rules, then package transmission is carried out to data, package idiographic flow for adding packet header distinguishing mark, add a point inclusion bag mark, verification add check digit, add recognition of devices ID and time data.Finally again the mode of these data wireless transmissions is sent to Surveillance center.
Above-described embodiment is a kind of preferred version of the present invention, not does any pro forma restriction to the present invention, also has other variant and remodeling under the prerequisite not exceeding the technical scheme described in claim.
