As then the 2nd transceiver receives the reception level that the 1st transceiver is sent and is all reduced to 0 or declines to a great extent.
In the present embodiment, as shown in Figure 2：" transceiver 1 ", " transceiver 2 ", " transceiver 3 " is constantly in 15 seconds circulation hairs
Send state, 15 seconds not timed out to be in reception state.Circulation countdowns in 15 seconds of transceiver 1 first are first reached, and " transceiver 1 " is sent
" 5 byte datas of numbering 1 ", " transceiver 2 " receives " 5 byte datas of numbering 1 " and preserved, and starts simultaneously at transmission " numbering 2
5 byte datas " and forward " 5 byte datas of numbering 1 "；" transceiver 3 " receives " 5 byte datas of numbering 1 " or " compiled
Numbers 25 byte datas ", start to send " 5 byte datas of numbering 3 " and forward " 5 byte datas of numbering 2 " and " the 5 of numbering 1
Byte data ".N are arrived by that analogy.
Rail is normally without under crack conditions, then rail transmission information can be reached normally, and " transceiver 3 " receives " transceiver 1 "
" it is not 0 that transceiver 2 ", which receives level,；" transceiver 1 ", " transceiver 2 " and " transceiver 3 " launching electrical level itself also be 0；
If there is broken rail phenomenon in rail such as figure, then " transceiver 3 " receive " transceiver 1 " and " transceiver 2 " receive level be all reduced to 0
Or decline to a great extent.
The major function of transceiver is that intercycle (the present embodiment is to be spaced for 15 seconds) transmission is originally by rail transmission signal
Body information data and the information data for forwarding other transceivers.Self-information data parcel launching electrical level data itself, receive
Preceding or preceding level data, detection battery electric quantity itself, monitor lightning protection device state and forward other transceiver information numbers
According to function.The structure of transceiver is by groups such as battery, power circuit, constant-current source circuit, single-chip microcomputer, carrier module, lightning-protection modules
Into.
System Working Principle see Fig. 4, except transceiver 1 (transceiver 1 is the 1st transceiver, and function is special, is introduced later)
Outside, all transceiver work have four kinds of states：Actively send data countdown state (waiting receive information data mode), data
Information re-ception state, collection level itself simultaneously send data message state, forward other Transceiver Data information states.
1. actively send data countdown state (waiting receive information data mode)：
Can slightly have difference because crystal oscillator opens the time of shaking, and in order to allow the carry out data of transceiver order successively to send without producing
Raw conflict, one is set to first power on autonomous transmission time point when we are electric on the transceiver, this time point is only carried out
Countdown, is not just used later, is terminated when first powering on autonomous transmission time countdown, transceiver independently sends one
Secondary data message, then formally enter after being sent completely and actively send data countdown state.Transceiver in this case, if
Countdown does not reach also, then is substantially at idle condition, in the state for receiving other transceiver information data；Assuming that can not
In the case of the data message for receiving other transceivers, transceiver can cycle through itself with the variable interval time that interval is set
Data message give other transceivers.The spontaneous circulation of transceiver 2 sent the time as the 15.667th second in such as figure, and transceiver 3 is autonomous
It is the 15.809th second etc. (the 1st transceiver spontaneous circulation transmission time is the 15th second) to cycle through the time.
2., data message reception state：
When transceiver, which has the initiative, sends data countdown state (waiting receive information data mode), before receiving or
The data message of preceding transceiver before person, then transceiver enter data message reception state.Under this state transceiver receive before or
Preceding Transceiver Data information is simultaneously stored in buffer area, and changed according to being the data of preceding or preceding transceiver of reception from
The main count down time counter for sending data, make its shorten can namely shift to an earlier date accordingly it is autonomous send data, equivalent to making
