FidonetFido.
As described in Fig. 5, Fig. 6, Fig. 7, in the present embodiment, entire control station is made of master control cabinet and multiple IO cabinets.It is main
Cabinet is controlled by power supply media board, controller (MPUA and MPUB each other master-slave relationship), network communication board (ECC) and I O board card group
At；IO cabinet is made of power supply media board, I O board card；Data acquisition in machine cage is responsible for by ECC, acquires DI plate by 25 millisecond periods
Card data, and markers is recorded on ECC board.Controller acquires data to the ECC of each IO machine cage by 50 millisecond periods.It is existing
Have in technology, designed according to primary network station, the board that master controller needs to acquire is excessive, takes long time, and can only be in master control
Device processed records markers.By one piece of 16 path computation of board, 84 pieces of DI boards are needed, master controller needs in 40 milliseconds of resolution ratio
Complete the acquisition of 84 pieces of DI boards.The acquisition time of average single board is 0.48 second.And the embodiment of the present invention uses second level
Network design (is provided with network communication board) between controller unit and data input/output interface, and ECC is responsible for acquisition
DI board data in single machine cage, I O board card quantity is 17 pieces in single machine cage.If being calculated by 25 millisecond periods, single DI plate
Card acquisition time is 1.47 milliseconds, and each ECC can recorde markers；Therefore, 40 milliseconds of resolution ratio may be implemented on ECC
Acquisition.It is calculated by 17 pieces of DI boards of single machine cage, 1344 point DI only need 5 IO machine cages, i.e. master controller only needs and 5
The communication of ECC Communication Card；It is minimum to the load pressure of master controller in this way.
Also, server is calibrated by RS485 and time corrector, preferably: time correction error is that 400ms adds server certainly
Most deviation ± 3ms, total 403ms of worst error or so in 60S meet server and are responsible for target requirement when " hour ".MPU
When board passes through time corrector pulse pair, maximum deviation is (± 3ms) in time-revise cycle, target requirement when meeting MPU " dividing "；It is different
Controller between maximum clock error be 6ms.ECC is responsible for beating the markers of " second " and " millisecond " to DI data packet.ECC board with
MPU carries out soft clock synchronization, network clock synchronization error by IOBUS-1 are as follows: takes time and network transmission (5ms)+Hub to transmit in MPU and prolongs
When (10us)+ECC receive data and parsing clock synchronization (1ms)=6ms.Time deviation in the ECC clock synchronization period are as follows: when ECC itself
Soft clock synchronization error (the 6ms)+redundancy time corrector of error (± 3ms)+network of clock deviation (± 3ms)+standard time to MPU are opposite accidentally
Difference (1ms)=± 13ms；40 milliseconds of precision is can satisfy due to beating markers on ECC, so ECC board and I O board card are not
It sets time.
In conclusion the markers of ECC board, either in station, between standing, markers disparity is no more than 32 milliseconds, completely
The resolution requirement of 40 milliseconds of foot.
Preferably, server unit in above-mentioned steps S3 show process include: 1), receive controller unit will be after operation
Data carry out data；2) processing of real-time data base task, is carried out to the data received；3), according to real-time data base task
Processing conjugates event action or switching value displacement operation as a result, determining to send；4) by coming out after judgement as the result is shown.Tool
Body, as shown in figure 4, the overall flow of data acquisition includes:
The acquisition of S409, DI hardware module data, i.e., the number of each data channel collection site sensor, executing agency etc.
According to；
S408, ECC module acquisition, i.e., after each hardware module data being stamped markers by ECC, data are packaged；
S407, controller unit acquisition, i.e. control unit, which are acquired, stamps markers by ECC and after communication Protocol Conversion
Data；
S406, control IO algorithm process, i.e., will from the collected data of network communication board according to controller unit inside
Pre-defined algorithm carry out logical operation；
