Transceiver positioned at rail monitoring section first end is as the 1st transceiver;1st transceiver, the n-th transceiver phase Increase by 485 telecommunication circuits, GPRS communication module than normal transceiver, pass through 485 telecommunication circuits, GPRS communication module and server Communication;1st transceiver, the n-th transceiver send data to corresponding GPRS communication module by 485 telecommunication circuits, and GPRS leads to News module is established to be connected by TCP/IP with server sends the data to server;N-th transceiver and the 1st transceiver pass through 485 telecommunication circuits carry out data exchange, communication baud rate 2400bps, the 1st transceiver and the n-th transmitting-receiving with GPRS communication module For device by 485 telecommunication circuits to GPRS communication module transmission frame format data, GPRS communication module receives data by TCP to control Center processed sends data.
Each transceiver carries out relay carrier communication using rail as wire, from the 1st transceiver to the n-th transceiver, in transmission Frequency of heart is 13.5KHz multicarrier communication signal, and server is that the signal that the n-th transceiver feeds back judges two according to the 1st transceiver Whether the rail between individual adjacent transceiver and rail junction has broken rail.When rail fracture, carrier signal reception level, Launching electrical level produces change, and acquired record and relay send relevant information to management module (the n-th transceiver, the 1st transceiver), Management module sends information to server analysis processing.
The transceiver in each rail monitoring section carries out relay carrier communication, and at interval of setting time t, (t can be 15s, most Big error 2s) state is cycled through successively.
2nd transceiver receives the data that the 1st transceiver is sent and preservation;I-th -1 transceiver, the i-th transceiver receive i-th -2 The data of transceiver transmission and preservation;1st transceiver receives the 2nd transceiver, the data that the 3rd transceiver is sent and preservation;Wherein, 3≤i≤n, n are the number that the rail monitors the every group of transceiver in section (the present embodiment only sets one group).
The data that each transceiver sends self information data and forwards its other transceiver received to send;Self information number According to including unique identification data, its own transmission level data, monitoring and its cells electric quantity data obtained, monitoring and acquisition Lightning protection device status data.
Each transceiver is constantly in using time t as the cycle and cycles through state, and reception state is in when having not timed out;The The time of 1 transceiver first reaches, and the 1st transceiver sends self information data, includes " 5 byte datas of numbering 1 ";2nd transmitting-receiving Device receives " 5 byte datas of numbering 1 ", and preserves, and starts simultaneously at and sends self information data, includes " 5 bytes of numbering 2 Data ", and the data for including " 5 byte datas of numbering 1 " for forwarding the 1st transceiver to send;3rd transceiver receives " numbering 1 5 byte datas " or " 5 byte datas of numbering 2 ", start to send its data, comprising " 5 byte datas of numbering 3 ", and Forward the 2nd transceiver send the data comprising " 5 byte datas of numbering 2 " and the 1st transceiver transmission include " the 5 of numbering 1 The data of byte data ";N are arrived by that analogy.
Rail is normally without under crack conditions, and rail transmission information can be reached normally, and the i-th transceiver receives the i-th -2 transceiver The reception level sent with the i-th -1 transceiver is not 0;I-th -2 transceiver, the i-th -1 transceiver and the i-th transceiver are launched in itself Level is not 0 yet;The data that all transceivers send and received can be normal.
If broken rail phenomenon occurs in rail, if the connection of the contact of the i-th -1 transceiver and rail, the i-th transceiver and rail Between rail broken rail phenomenon occurs, then the i-th transceiver receives the reception electricity that the i-th -2 transceiver and the i-th -1 transceiver are sent It is flat to be all reduced to 0 or decline to a great extent.
If broken rail phenomenon occurs in rail, if the junction of the i-th -2 transceiver and rail, the i-th -1 transceiver and rail Broken rail phenomenon occurs for the rail between junction, then the reception level of the i-th -1 transceiver of the i-th transceiver reception is normal, but receives The reception level that i-th -2 transceiver is sent is reduced to 0 or declined to a great extent.
Show if broken rail occurs for the rail between the junction of the junction of the 1st transceiver and rail, the 2nd transceiver and rail 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 Transceiver below sends data message immediately with the transceiver before this.As shown in Figure 4, transceiver 1 is independently sent completely After data message, transceiver 2 receives the count down timer that the data message of transceiver 1 independently sends data originally and also had 500, But because receiving the data message of transceiver 1, then count down timer is changed 250, that is, transceiver 2 will in advance 250 Start to send data message.The like transceiver 3, transceiver 4 all can before receiving or preceding data message and incite somebody to action from Main transmission data time shifts to an earlier date.
3., collection level itself and send data message state:
After it have modified autonomous count down timer for sending data itself, when countdown is completed, data message is entered Transmission state.Transceiver in this case, transmission level of transceiver collection itself, cell voltage state itself, lightning protection device state And store data in corresponding buffering area, and corresponding data bit is removed or set according to state, data preparation is complete Start carrier module after finishing to send in data message.Data message itself sends 3 times 5 byte datas in order to ensure success. Transceiver 1 sends " 5 byte datas of numbering 1 " in Fig. 4 and transceiver 2 sends " 5 byte datas of numbering 2 " and transceiver 3 It is all data message itself to send " 5 byte datas of numbering 3 ".
4., forward other Transceiver Data information states:
Transceiver then enters after data message itself is sent completely by carrier module forwards other Transceiver Datas letter Breath state.Above transceiver is under data message reception state by transceiver in this case receive before or it is preceding receive Send out device data message by carrier module by 5 bytes once in the form of be forwarded to other transceivers.As transceiver 2 is sent out in Fig. 4 Send " 5 byte datas of numbering 1 ", transceiver 4 can send " 5 byte datas of numbering 3 " and " 5 byte datas of numbering 2 ".
After transceiver 1 independently sends " 5 byte datas of numbering 1 " in Fig. 4, transceiver 2 receives " 5 bytes of numbering 1 Data " then change the autonomous transmission time, send " 5 byte datas of numbering 2 " in advance and simultaneously forward " 5 byte datas of numbering 1 ", receive Hair device 3 receives " 5 byte datas of numbering 1 " or " 5 byte datas of numbering 2 ", and then modification independently sends the time, sends out in advance Send " 5 byte datas of numbering 3 " and forward " 5 byte datas of numbering 2 " and " 5 byte datas of numbering 1 ", transceiver 4 receives " 5 byte datas of numbering 2 " or " 5 byte datas of numbering 3 " then modification independently sends the time, sends " the 5 of numbering 4 in advance Byte data " simultaneously forwards " 5 byte datas of numbering 3 " and " 5 byte datas of numbering 2 ", is being down last transceiver The reception of (the n-th transceiver, present embodiment in n=5), the 5th transceiver receive data and do not forward but establish TCP by GPRS Service is uploaded to server and carries out data processing.
And the 1st transceiver is with other transceiver differences, transceiver not only has four kinds of states of the above, and the 1st transceiver is also There is the function of management module, can be communicated by 485 telecommunication circuits with GPRS communication module, upload the transceiver received 2 and the data message of transceiver 3.
The major function of 1st transceiver and the n-th transceiver is to concentrate each transceiver information by rail carrier communication to beat Bag, the 1st transceiver and the n-th transceiver are sent to GPRS communication module by 485 telecommunication circuits, and GPRS communication module leads to data Cross TCP/IP and server establishes the link and is sent to server.
When 1st transceiver is in the data countdown state that actively sends (waiting receive information data mode), it can be spaced The launching electrical level collection of progress in 3.75 seconds itself, and train is preserved by caused high level, when independently sending data, high electricity Flat data are sent;When 1st transceiver is in data message reception state, the reception electricity of transceiver 2 and transceiver 3 can be received Put down and preserve, after the completion of independently data are sent, the server that data message is uploaded to control centre by GPRS module is carried out Data Management Analysis.
When n-th transceiver is in the data countdown state that actively sends (waiting receive information data mode), it can be spaced 5 seconds Progress launching electrical level collection itself, and train is preserved by caused high level, after the completion of independently data are sent, pass through GPRS The server that module uploads data message control centre carries out Data Management Analysis.
Because rail is directly exposed to earth's surface, for semiautomatic block section, there is no lightning rod, thunder directly over rail When percussion is raw, lightning current can import the earth by rail, and for the equipment being joined directly together with rail, lightning protection seems ratio It is more important.It is a kind of practical ways to install SPD (Surge Protector).If SPD damage equipment can alarm immediately.
The also detectable battery electric quantity of equipment, if battery electric quantity is too low, equipment can report " battery electric quantity is low " to warn, please be timely Change battery.
Transceiver forms link by the way of transmission information one by one, can pass through the break-make of link, receive information and letter Number intensity judges rail broken rail, if pressure rail.Because weather reason (exposing to the sun and rain, wind and frost sleet) causes railway roadbed resistance not One, received signal strength occurs therewith can also change.
Judge broken rail point by 3 transceivers:1st transceiver sends data by rail, and transceiver 2 is sent by rail Data, transceiver 3 receive data by rail;If rail is normal and without pressure rail (double track is not turned on):Transceiver 3 is connect by rail The 1st transceiver, " carrier signal of rail " of transceiver 2, the state 0 of reception signal are received, and is inscribed in the time of lasting wait The state of the collection of letters number is 0 always, then judges " broken rail " fault message.Extend to three transceivers of arbitrary neighborhood:Pass through 3 Individual transceiver judges whether broken rail point:I-th -2 transceiver sends data by rail, and the i-th -1 transceiver is sent out by rail Send data;I-th transceiver receives the rail carrier signal of the i-th -2 transceiver, the i-th -1 transceiver by rail, if reception signal State 0, and in the setting time of lasting wait reception signal state always be 0, then judge there is broken rail failure;Its In, 3≤i≤n.
Judge device transceiver quality by 3 transceivers or whether there is train to pass through:Receive " the rail of transceiver 2 Carrier signal " state be 0, then see receive the 1st transceiver " carrier signal of rail " state, if receiving state signal is 1 or 2, judge " transceiver 2 is bad ";If " carrier wave transmission level " becomes big, judge " train passes through ".Extend to any phase Three adjacent transceivers:If the state that the i-th transceiver receives the rail carrier signal of the i-th -1 transceiver is 0, further according to reception Rail carrier signal state to the i-th -2 transceiver is determined whether;If receive the rail carrier wave letter of the i-th -2 transceiver Number state is 1 or 2, judges the damage of the i-th -1 transceiver;If the rail carrier signal state for receiving the i-th -2 transceiver is load Ripple transmission level becomes big, then is judged as that train passes through state.

    Rail to be monitored is divided at least rail monitoring section, the both ends in each rail monitoring section are respectively equipped with short-circuit line;Or Person, is not provided with short-circuit line, and the 1st receiver, n-th transceiver at both ends connect the both ends in monitoring section respectively;
    Each rail monitoring section distribution sets some transceivers, the distance of rail between adjacent transceivers and corresponding rail junction For 0.5~1km, the junction 40 of the 1st transceiver, the junction corresponding short-circuit line of distance of the n-th transceiver and rail and rail~ 80m;
    Transceiver positioned at rail monitoring section first end is as the 1st transceiver;1st transceiver, the n-th transceiver are compared to general Logical transceiver, 485 telecommunication circuits of increase, GPRS communication module, the 1st transceiver, the n-th transceiver by 485 telecommunication circuits to GPRS communication module transmission frame format data, communication baud rate 2400bps, GPRS communication module receive data by TCP to Control centre sends data;
    Each transceiver carries out relay carrier communication, transmission center frequency using rail as wire, from the 1st transceiver to the n-th transceiver Rate is 13.5KHz multicarrier communication signal;When rail fracture, carrier signal receives level, launching electrical level produces change, through adopting Collection record and relay send relevant information to management module, and management module sends information to server analysis processing;Server Judge whether the rail between two adjacent transceivers and rail junction has broken rail by the data of reception;
    The transceiver in each rail monitoring section carries out relay carrier communication, and state is cycled through successively at interval of setting time t, or Person sends setting data after the data of setting transceiver transmission are received;
    2nd transceiver receives the data that the 1st transceiver is sent and preservation;I-th -1 transceiver, the i-th transceiver receive the i-th -2 transmitting-receiving The data of device transmission and preservation;1st transceiver receives the 2nd transceiver, the data that the 3rd transceiver is sent and preservation;Wherein, 3≤i ≤ n, n are the number that the rail monitors the every group of transceiver in section;
    The data that each transceiver sends self information data and forwards its other transceiver received to send;Self information packet Include unique identification data, its own transmission level data, monitoring and its cells electric quantity data obtained, monitoring and the lightning protection obtained Unit state data;
    Each transceiver is constantly in using time t as the cycle and cycles through state, and reception state is in when having not timed out;1st receives The time of hair device first reaches, and the 1st transceiver sends self information data, includes " 5 byte datas of numbering 1 ";2nd transceiver connects " 5 byte datas of numbering 1 " are received, and are preserved, starts simultaneously at and sends self information data, include " 5 byte numbers of numbering 2 According to ", and the data for including " 5 byte datas of numbering 1 " for forwarding the 1st transceiver to send;3rd transceiver receives " numbering 1 5 byte datas " or " 5 byte datas of numbering 2 ", start to send its data, comprising " 5 byte datas of numbering 3 ", and turn Send out the 2nd transceiver transmission the data comprising " 5 byte datas of numbering 2 " and the 1st transceiver transmission include " 5 words of numbering 1 The data of joint number evidence ";N are arrived by that analogy;
    Normally without under crack conditions, rail transmission information can be reached normally rail, and the i-th transceiver receives the i-th -2 transceiver and the The reception level that i-1 transceivers are sent is not 0;I-th -2 transceiver, the i-th -1 transceiver and the i-th transceiver launching electrical level itself It is not 0 yet;The data that all transceivers send and received can be normal;
    If there is broken rail phenomenon in rail, if the junction of the contact of the i-th -1 transceiver and rail, the i-th transceiver and rail it Between rail broken rail phenomenon occurs, then the i-th transceiver receives reception level that the i-th -2 transceiver and the i-th -1 transceiver are sent all It is reduced to 0 or declines to a great extent;
    If broken rail phenomenon occurs in rail, if the connection of the junction of the i-th -2 transceiver and rail, the i-th -1 transceiver and rail Between rail occur broken rail phenomenon, then the i-th transceiver receive the i-th -1 transceiver reception level it is normal, but receive i-th -2 The reception level that transceiver is sent is reduced to 0 or declined to a great extent;
    If broken rail phenomenon occurs for the rail between the junction of the junction of the 1st transceiver and rail, the 2nd transceiver and rail, 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 addition to the 1st transceiver, all transceiver work have four kinds of states:Actively send the data countdown state letter to be received such as i.e. Breath data mode, data message reception state, gather itself level and send data message state, forward other Transceiver Datas Information state;
    (1) actively send data countdown state, wait 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 punching It is prominent, set one to first power on autonomous transmission time point when electric on the transceiver, this time point only carries out once falling to count When, just do not use, terminate when first powering on autonomous transmission time countdown, transceiver independently sends a data letter later Breath, then formally enter after being sent completely and actively send data countdown state;Transceiver is in this case, if countdown is also Do not reach, be then substantially at idle condition, in the state for receiving other transceiver information data;Assuming that other can not be received In the case of the data message of transceiver, transceiver can set variable time with interval and cycle through the data message of itself to it His transceiver;
    (2) data message reception state:
    When transceiver have the initiative send data countdown state wait receive information data mode when, receive preceding transceiver Or the data message of preceding transceiver, then transceiver enter data message reception state;Under this state transceiver receive before or Preceding Transceiver Data information and buffer area is stored in before person, and is the data of preceding or preceding transceiver and changes according to reception The autonomous count down time counter for sending data, makes its shortening, i.e., corresponding transmission data autonomous in advance, equivalent to making below Transceiver sends data message immediately with the transceiver before this;
    (3) gather itself level and send data message state:
    After it have modified itself autonomous count down timer for sending data, when countdown is completed, data message transmission is entered State;In this case, transceiver gathers itself transmission level, its cells voltage status, lightning protection device state and handle to transceiver Data storage is removed in corresponding buffering area, and according to state or sets corresponding data bit, after data preparation Start carrier module to send in data message;In order to ensure being successfully transmitted its data information, its data information is sent out Send some times;
    (4) other Transceiver Data information states are forwarded:
