Gain unit 230 receives and reads the sampled data and outputting communication data, and the gain unit 230 reads the triggering letter
Number when, the duty field that the gain signal is superimposed in the intermediate data is to form the communication data, gain signal
Setting it is different from trigger signal, in order to form communication data, set a magnitude of voltage different from trigger signal, sampled data
Gain signal, makes each other pressure detecting modules 200 to filter out the signal from bus, thus judge whether to
The sequence of itself, if the logical one of such as intermediate data is 3V, gain signal can elect 1V or 5V as, can thus lead to
Later module identification this gain signal is continued；Gain unit 230 can by way of boosting or decompression mode, preferably rise
The mode of pressure, it is to avoid because the disturbance of sampled data or trigger signal causes filter element 260 by false triggering, shown in reference picture 3, institute
Stating gain unit 230 includes booster circuit 234, latching circuit 233, first switching element 231 and second switch element 232；
The first switching element 231 connects the latching circuit 233 and the booster circuit 234, and the first switching element 231
Action is so that the latching circuit 233 and the booster circuit 234 work when receiving the trigger signal；The booster circuit
The gain signal is exported during 234 work；The latching circuit 233 is configured with the first delay time, the work of latching circuit 233
Output continues the shielded signal of the first delay time to the second switch element 232 when making；The second switch element 232 connects
It is connected between the first switching element 231 and the input of the gain unit 230, the second switch element 232 is received
End to disconnect the connection between the first switching element 231 and the input of the gain unit 230 during the shielded signal.
The logic of control is as follows, when an intermediate data output is that first switching element 231 triggers booster circuit 234 and latching circuit
233 work simultaneously, one gain signal of formation of booster circuit 234, export to output unit 240, and now signal is just duty
Field, so ensure that gain signal can be directly superimposed to duty field, and latching circuit 233 works, and controls second switch
Element 232 ends, now, in the first delay time, and first switching element 231 would not receive any signal triggering, so
Avoid the mistake that sampled data is identified as to trigger signal, it is ensured that reliability, and the first delay time can directly pass through meter
The data volume of intermediate data is calculated, and the speed of output obtains the first delay time；First switching element 231, second switch element
232 could be arranged to the triode with switching function, IGCT, the device such as FET, do not do and limit to, and latching circuit
233 can be realized by delay circuit, and booster circuit 234 is preferably that 3-5V boost chips are realized, can also be configured to 3-1V drops
Pressure chip is used as reduction voltage circuit output gain signal.
Output unit 240, is connected between the gain unit 230 and the communication node 201, and described for exporting
Communication data is to the communication bus 101；The output unit 240 is configured with delay circuit, and the delay circuit is configured with
One preset time, when the output unit 240 receives a communication data, after the first preset time of delay, by the communication data
Send to communication bus 101, the first delay time is shorter, can be Microsecond grade delay, but need set delay circuit with
It is easy to regulating time benchmark, to the maintenance and debugging of device.
Input block 250, is connected to the communication bus 101, for receiving the communication data, it is seen then that output unit
240 are each coupled to communication node 201 with input end member, even if the interface of the formation multiplexing of communication node 201, and can pass through timesharing
Mode carry out data reception and send operation；
Filter element 260, is connected to the input block 250, is configured with the first voltage that correspondence first voltage value is set
Scope, and gain signal is screened from the communication data according to the first voltage range；Filter element 260 sets more simple
It is single, annular comparator can be passed through, it is possible to set a voltage range for allowing first voltage value to pass through, list can also be passed through
Individual comparator, because gain signal is bound to be less than or greater than sampled data and trigger signal, so passing through single comparator
The sampling screening of gain signal can be carried out, so communication signal is in bus, each filter element 260 is believed all without by other
Number influence, can by communication bus 101 through filter element 260 judge obtain communication signal.
Counting unit 270, is connected to the filter element 260, including one overflows end, and the spilling end is connected to the number
According to processing unit 220, a sequential value is configured with, when the number of times of reception gain signal reaches the sequential value, the counting list
One spill over is to the spilling end and resets the number of times of the gain signal for the output of member 270, and the concept of sequential value is specific such as
Under, due to needing when a pressure detecting module 200 is exported, other pressure detecting modules 200 are taken all without work
The mode of time-sharing multiplex channel, requires that exception occurs in a too high pressure detecting module 200 to time precision, may result in data
Confusion, and data corruption is unpredictable, so the influence and destruction that are produced to system can not be predicted, so being each
The configuration sequential value of counting unit 270 is particularly critical, and sequential value is illustrated, and each counting unit 270 can be triggered once, sequence
Represent the order that each pressure detecting module 200 is exported, such as sequential value for 1 counting unit 270 be configured as first it is defeated
Go out, due to being bus communication, all pressure detecting modules 200 can all be triggered because of gain signal so that counting unit 270 puts 1,
But only have a counting unit 270 and overflow, the output intermediate data of control data processing unit 220 sends the data
To bus to communication interface 100, and now, because other pressure detecting modules 200 are in bus, then all to count single
Member 270 puts 2, and sequential value overflows for 2 counting unit 270, sequentially, and it should be noted that being instructed for a sampling, each
A pressure detecting module signal of 200 output, so during the spilling of single counting unit 270, can self-shileding under certain condition
Work, logic has following two, and a kind of is the configuration according to the time, if for example all outputs of pressure detecting module 200 are completed
Time used is 23 seconds, then first counting unit 270 configures the self-shileding working time of 25 seconds, realizes the screen of itself
Cover, two be that counting unit 270 is configured with another masking value, each masking value of counting unit 270 and sequential value and be equal
(being equal to the sum of pressure detecting module 200), and during sequential value correspondence spilling, masking value is started counting up, until masking value correspondence is overflow
When going out, sequential value restarts to count, so, and under a sampling instruction, each pressure detecting module 200 only sends one
Secondary communication data；Shown in reference picture 1, sequential value follows the communication interface 100 and the corresponding pressure detecting module 200
The increase of physical distance increases successively, can so ensure the efficiency of data transfer.Each correspondence of the counting unit 270
Sequential value it is different and continuous successively, during so that each counting unit 270 exporting spill over, the communication data of correspondence output makes
Counting unit 270 positioned at next sequential value exports spill over.
The sequential value of each counting unit 270 is that one first constant subtracts one first dynamic value, the counting unit 270
When receiving a transfer signal, the first dynamic value, each institute of counting unit 270 according to the content changing of the transfer signal
Corresponding first constant is different；For example, assuming that sequential value is 1 pressure detecting module 200, corresponding first constant is 1, then
Its first dynamic value is 0；And sequential value is fast for 2 pressure detecting film, corresponding first constant is 2, and the first dynamic value is all mutually 0,
Order is set successively, then if necessary to which sequential value is closed into (the spilling end of counting unit 270 for 1 pressure detecting module 200
For 0 or negative when close automatically), then the first dynamic value for being sent to bus is 1, then the sequential value that originally sequential value is 2 just becomes
Into 1, sequential value is 10 and becomes 9, so can just control a part of pressure detecting module 200 to close, and improves
The efficiency of communication.
When transfer of the formation of communication bus 101 one comprising the transfer signal is instructed, by each input block 250
Receive described transfer to instruct, the filter element 260 screens the transfer signal from the transfer instruction and counts list to described
Member 270, transfers the setting of instruction, can be the signal that magnitude of voltage is second voltage value, such as magnitude of voltage is 7V, single by filtering
Member 260 obtains data with same logic, changes the sequential value of counter.
The data processing unit 220 works when receiving the spill over, and intermediate data described in output one is to export pair
The communication data answered.
