Specifically, during each terminal device initialization, 1 pin of each terminal device exports high level, i.e., all terminals
The control line of equipment is high level, and at this time with door output for high level, each 7 pin of terminal device detects high level, not into
Any action of row；When the first terminals of any terminal equipment (N.1, for example, 1.1,2.1) send out " 0 " control data order when, with
Door output is " 0 ", and the first terminals of each terminal device detect low level, and other terminal devices are forbidden sending out by software control
Send request control command；And then corresponding control unit allows to send out the terminal device of control command and the connection of bus connects
Logical, power supply control network allows the terminal device to GPS/ Big Dipper bimodulus module for power supply, you can complete single terminal end equipment with
The request interaction of GPS/ Big Dipper bimodulus modules, and then located in connection and time service data information are obtained, avoid the waste of resource.
In one of the embodiments, as shown in figure 4, the number of transceiver is two, respectively first transceiver and the
Two transceivers, first transceiver and second transceiver are mainly received through RJ-45 interfaces 30 with differential decoding information, and will solution
Code information is merged into single-end information, and wherein differential decoding information includes RX+、 RX-、TX+、TX-、1PPS+、1PPS-, VCC, GND,
Wherein RX+And RX-It is a differential pair information, represents data receiver；TX+And TX-It is a differential pair information, represents data hair
It send；1PPS+And 1PPS-It is a differential pair information, represents pps pulse per second signal.In addition, differential signal becomes difference by transceiver
Into single-ended.Optionally, difference RX+、RX-Become RXD through first transceiver, TXD is mainly responsible for the pattern choosing of the transmission GPS/ Big Dippeves
Select order, the order of decoded information transmission rate, GPS/ Big Dipper bimodulus module start order (including cold start-up, thermal starting etc.), eventually
Current location order and current time order etc. where end equipment； TX+、TX-Become TXD through first transceiver, TXD data pass
Defeated line is mainly responsible for the data transmissions such as longitude in decoded information, latitude, time, height；Difference 1PPS+、1PPS-Through the second transmitting-receiving
Device becomes 1PPS, and PPS represents pulse letter signal, is mainly responsible for time pulse signal transmission.
In a kind of optional embodiment, first transceiver is RS422 transceivers, and ISL83077EIBZA can be selected.
Second transceiver is RS422 transceivers, selects ISL83078EIBZA.Data, antijamming capability are transmitted using differential lines form
By force, and long transmission distance, up to 300 meters.
Each technical characteristic of above example can be combined arbitrarily, to make description succinct, not to above-described embodiment
In each technical characteristic it is all possible combination be all described, as long as however, the combination of these technical characteristics be not present lance
Shield is all considered to be the range of this specification record.
Above example only expresses the several embodiments of the utility model, and description is more specific and detailed, but simultaneously
Cannot the limitation to utility model patent range therefore be interpreted as.It should be pointed out that the ordinary skill people for this field
For member, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this reality
With novel protection domain.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
