Battery cell monitoring unit=0x01-0x04
Simulation monitoring unit=0x05
Digital supervision unit=0x06
Clock and data record unit=0x07
Communication unit=0X08
The expansion equipment address is followed successively by 0X0A, 0X0B, 0X0C, 0X0D intelligence serial ports.
Order sign ML, in order to determine the corresponding relation of an order and its reply data, i.e. order is identical with the MI of the Frame of its correspondence, and the numerical value of MI is one 16 system number, and numerical value is from 01-0xCA.The MI value of present embodiment mainly obtains from the PC command frame, the command frame that non-PC originating end is initiated, and the value of MI is C1H.
Command body MC, promptly Ming Ling concrete operations content by 3 16 system numeric representations, can be formed thousands of orders by the content of DA and MC.
Concrete data DC adopts the binary-coded decimal data representation, and DC is with data content by Frame, and its length is 0-50byte, and the data of battery pack and analog quantity are represented with binary-coded decimal, the data binary number representation of digital quantity.
Do not respond after the DRT module is retransmitted three times, then complain to frame to COMM module sending module fault.
This agreement can be according to the specific requirement of using, definition command body MC and corresponding data DC, thus can adapt to the application of different dcss.
Each software module function of present embodiment is single, design simple relatively, easy software modification, edition upgrading is convenient relatively.
The major function of FSU dynamic environment monitoring software is: in service, by its control, finish the power of whole base station and collection, processing, transmission and the relevant control action of environmental data to hardware circuit.The monitoring software design of entire equipment is the same with its hardware configuration, adopt the functionalization modular design, different software function modules is loaded among the CPU of different hardware module, identical hardware capability module, it software function module also identical, modular software design has following characteristics:
With each hardware module correspondence, whole FSU software detects software module, analog quantity detection software module, digital quantity detection software module, clock log software module and full-duplex communication software module by storage battery and forms.
Each software module is independent mutually, and each module division of labor is clear, does not intersect mutually, overlapping.
Each software module is carried out data by internal flow of information and is transmitted and exchange.Internal flow of information one is the information exchange between each sample detecting module and the clock log module, provide information to data record, internal flow of information two is the information exchange between each module and each the full-duplex communication module, and external information stream is the information exchange of full-duplex communication module and Surveillance center.The parallel running simultaneously of each software module, the speed of service is fast, and data processing is real-time.
The microdata structure is adopted in inside and outside information interchange, and communication frame is simple in structure, and communication speed is fast flexibly, the treatment effeciency height, and increase or modification control command are convenient.Each software module function is single, design simple relatively, easy software modification, edition upgrading is convenient relatively.
The following performance of FSU software makes it have very strong fault-tolerant error correcting capability, guarantees that running software is safe and reliable:
Have " source address " DS and " destination address " DA in the command frame of software and the data frame structure, different modules and external smart machine mouth, be assigned different " address ": 1# battery module address is 01,2# battery module address is 02,3# battery module address is 03,4# battery module address is 04, the analog signal detection module address is 05, digital quantity detection module address is 06, and the clock log module's address is 07, and the full-duplex communication module's address is 08,1# smart machine port address is 0A, 2# smart machine port address is 0B, and 3# smart machine port address is 0C, and 4# smart machine port address is 0D.Each software module is judged order and the data of receiving according to oneself " address ", whether to one's name, otherwise will be not one's own information, perhaps the information of " address " mistake is kept outside of the door.
The command frame of software has more rigorous command body MC structure, each module " address " and the combination of command body, make that each bar order all is " unique " in whole command set, so each software module is easy to the bad command content of receiving is ignored.
Data among the data volume DC in the frame structure of software are that binary-coded decimal is formed, it is except having than the high command body MC of getting of ASCII character, they all by 16 system numbers constitute-form, like this, the expression efficiency that each software module is many, to obviously be different from other parts in the frame structure-frame head SOF, postamble EOF simultaneously, when receiving and send data, can be because of the randomness of data value and random the generation and frame head SOF, postamble EOF, obscuring of command body MC content and make a mistake.
Each module has hardware and software combination " house dog " and (Watchdog) restarts function, in case owing to disturb strongly, when producing the software module run-time error, CPU will be restarted automatically, and software module is recovered normal and moved.
The FSU internal module connects by communication link, and the module that goes wrong can change mode of operation into listen mode automatically, can not send data, therefore can not influence other modules and normally move.
