See also shown in Figure 3, it collects the System Operation simplified diagram for electric motor car run book of the present invention, show when native system is out in accompanying drawing, at first carry out the initialization of native system various functions, by switching to a wherein state in the quadravalence control module, in CAN Bus module data transmission, native system is with in running order again, and be returned to the quadravalence control module and carry out electric motor car monitoring or switch arbitrary state of a control, and CAN Bus module is idle no data native system and is dormancy and gets back to original state; When so native system is applied to electric motor car collection vehicle data, occur getting final product triggering system work in case want to gather information, lose the electric motor car run book and do not have.
About quadravalence control module of the present invention operation and between state switch, please coordinate and consult following explanation and Fig. 4 to shown in Figure 8;
This quadravalence control module, it includes system's starting state, an inerrancy state, a passive error condition and a positive error condition, inerrancy state and passive error condition in the detecting without CAN Bus signal CAN Bus enter system hibernates; Include the storage mistake when wherein this inerrancy state switches to positive error condition; Enter this positive error condition by this passiveness error condition, and carry out trouble hunting, control program with this positive wrong shape and reset errorlessly, store simultaneously and return passive error condition; Without detecting CAN Bus signal, system enters dormancy in passive error condition.
This system's starting state includes memory function inspection, CAN Bus receiving check, GPS receiving check, GPRS I/O inspection, rtc signal inspection, GPIO/LED inspection, when completing above-mentioned check process, system starts successfully, not system's starting state failure of success of above-mentioned any one inspection, as shown in Figure 5 in accompanying drawing.This memory function inspection includes SPI I/O pin position, FAT16 archives economy, plug-in storing media, built-in archives; CAN Bus receiving check includes CAN Bus pin position, shielding and filtrator, inerrancy signal; The GPS/GPRS receiving check includes that UART pin position, GPRS user's title and password, GPRS network are online, data transmission receives; The rtc signal inspection includes I2C pin position, RTC time data; GPIO/LED checks and includes GPIO and LED setting.
This inerrancy state CAN Bus running, and include every N and carry out the record of CAN Bus signal capturing side, every N second and write plug-in storing media and every N second second with the GPRS encapsulated delivery; When this inerrancy state normally moves in system, triggered with CAN Bus filtrator by CAN Bus running, and received by CAN Bus data, separately provide the setting-up time interval to carry out CAN Bus signal capturing side with timer and record to the plug-in storing media, and the GPRS data transmission, as shown in Figure 6.
This passiveness error condition running includes every N and carries out the record of CAN Bus signal capturing side, lights miscommunication caution LED lamp and carried out the GPS/GPRS replacement in every N minute second; This passiveness error condition is when system exception moves, when as abnormal in GPS/GPRS I/O appearance, CAN Bus running triggers with CAN Bus filtrator, and received by CAN Bus data, light simultaneously miscommunication caution LED lamp, and provide with timer in addition and carry out CAN Bus signal capturing side between the setting district and record to the plug-in storing media, and GPS/GPRS resets, as shown in Figure 7.This passiveness error condition is in GPS/GPRS resets, and it includes, and UART pin position, GPRS user's title and password, GPRS network are online, the data transmission reception.
This positive error condition running include the system of lighting stop caution LED lamp, carry out CAN Bus and reset, carry out GPS/GPRS and reset, store replacements, carry out that RTC resets and every N divides and carries out system control program (Main Code) and reset and inspection.This positive error condition is to carry out system failure maintenance, when above-mentioned inerrancy state and passive error condition occur storing when abnormal, this system switches to positive error condition, the system of lighting stops that caution LED lamp, CAN Bus are reset, GPS/GPRS resets, store replacements (at this take the plug-in storing media as example), carry out that RTC resets and every N divides and carries out system control program and reset and inspection, as shown in Figure 8.By collocation, the state switched design between above-mentioned quadravalence control module, provide system to carry out the collection of electric motor car run book under optimum working mode.
For the dismounting of native system data and package module, see also Fig. 9 and shown in Figure 10, when data appears in CAN Bus, to carry out according to the CAN ID of its data the demand property judgement, deletion when not meeting, the data that is about to when meeting loads in CAN Buffer group, and begin to carry out data encapsulation, at first encapsulate the time data territory of RTC, second step loads the GPS positional information hurdle of GPS Module, after data was completed encapsulation, this moment, package contained the contents such as GPS, RTC, ID, DLC and Data, and first deposited wait storage or transmission in SD Buffer and GPRS Buffer in.System will be with the triggering of time timer as data storage and transmission, package is stored in the plug-in storing media (at this take the SD card as example) through store controller in by SD Buffer group when storing trigger condition and set up, and when the transmission condition is set up, with packet information by taking out in GPRS Buffer group, and send after loading SOF and EOF field.
After native system screens through judgement by above-mentioned data, through partition and encapsulation restructuring, effectively reduced the volume of information 30% to 50%, the storage area of saving and transmitting bandwidth are further arranged, expending under minimum storage area and wireless frequency range, carrying out the gather material of electric motor car operation; And native system utilizes the flow condition of gathering information on CAN Bus, to the action adjustment of data logging and transmission, really can save transmitting bandwidth and storage area, does not lose and do not have the defective of wanting to gather information.
After introducing via above-mentioned every explanation and accompanying drawing, can understand the present invention's " the electric motor car run book collects system ", improve direct mode after previous acquisition data, and utilize the continuity Variation Features of CAN Bus transmission, develop the data encapsulation that is applicable to vehicle electric energy, battery cell monitoring and storage, transmission architecture.
