Description

Technical Field

[0001] The invention relates to a railway on-track operation protection safety monitoring management method and system, belonging to the technical field of railway safety protection. Background Art

[0002] At present, railway on-track operations include fixed-point on-track operations in fixed operating areas and patrol on-track operations without fixed operating areas. The protection work is basically carried out by manually notifying the approaching train and requiring the operating personnel to get off the track in time to avoid it. The station liaison obtains the train passing information at the operating position and uses the intercom to inform the on-site protection personnel in advance, notifying the members of the operating team to get off the track to avoid the train or stop the operation on the adjacent line, requiring key trains to get off the track 10 minutes in advance, and non-key trains to get off the track at least 1 section in advance. However, due to lax control of key points, negligence and carelessness of personnel, and noisy environment at the operating site, the protection fails, which leads to frequent injuries of vehicles during railway on-track operations. Therefore, after the incident, only accountability can be pursued afterwards, and the protection failure cannot be fundamentally prevented.

[0003] In recent years, scientific and technological personnel from various places have conducted research on the technical means of railway on-road protection and have achieved certain results. For example, the Chinese patent application with application number CN201510463915.0 discloses a method for real-time identification of railway human-machine-environment relationship. This method uses a system composed of the railway Beidou ground-based enhanced CORS data center, locomotive high-precision airborne equipment, high-precision positioning portable equipment for operators, and a monitoring prediction and early warning center to dynamically calculate whether the running locomotive poses a safety threat to each operator on the road and the degree of the safety threat, so as to achieve unsafe early warning. Although this solution can provide unsafe early warning, it does not judge whether the on-site operators will leave the road in time after the early warning, and does not provide subsequent related measures.

[0004] Therefore, the current protection process is mainly at the hazard detection level, and does not provide information on how to effectively ensure the safety of operators when the hazard is detected, thereby failing to fundamentally prevent vehicle injury accidents from occurring. Summary of the invention

[0005] The purpose of the present invention is to provide a railway on-track operation protection safety monitoring management method and system to solve the problem that vehicle injury accidents cannot be fundamentally prevented during the current railway on-track operation protection process.

[0006] In order to solve the above technical problems, the present invention provides a railway on-track operation protection safety monitoring management method, which includes the following steps:

[0007] 1) When it is detected that the on-site workers need to leave the road or stop working, send warning information to the on-site operation team members;

[0008] 2) Within the set time of issuing the warning information, the application terminal determines whether the information sent by the on-site protection personnel through the intercom to confirm that all the working groups have left the road is received;

[0009] 3) If it is not received, an alarm will be issued and the warning information will be sent again until it is received or the distance between the operation position and the oncoming vehicle on this line is less than the set distance. If it is received, the positioning data of the positioning terminal will be used to verify whether all vehicles have actually left the road;

[0010] 4) If the message is received but the verification fails or it has not been received, a stop message will be sent to the oncoming vehicle when the distance between the operation position and the oncoming vehicle on this line is less than the set distance.

[0011] Furthermore, sending the warning information to the working group members in the step 1) refers to sending the warning information to the walkie-talkie on the on-site protection officer, and controlling the walkie-talkie and the positioning terminal to sound an alarm; the warning information re-issued in the step 3) refers to sending the warning information to the walkie-talkie on the on-site protection officer and the positioning terminals on the on-site workers and the on-site protection officer at the same time.

[0012] Furthermore, sending the warning information to the on-site workers in step 1) and step 3) refers to sending the warning information to the intercom on the on-site protection personnel and the positioning terminals on the on-site workers and the on-site protection personnel at the same time.

[0013] Furthermore, the warning information sent to the walkie-talkie is realized through the communication method of the voice channel and / or the digital radio; the warning information sent to the positioning terminal is realized through the communication method of the 4G / 5G network and / or the digital radio.

[0014] Furthermore, the information confirming that all the work groups have left the channel is sent to the server of the signal tower by the intercom in the form of voice and / or key data.

[0015] Furthermore, the method also includes issuing an alarm when exceeding the protection distance, exceeding the specified working area or communication loss is detected; exceeding the protection distance means that the on-site protection officer and the farthest on-site worker exceed the specified protection distance, and exceeding the specified working area means that the on-site worker exceeds the registered working position of the current work; communication loss means that the communication between the walkie-talkie on the on-site protection officer and the server in the signal tower is interrupted.

[0016] Furthermore, in the event of a communication loss, the on-site protection officer's walkie-talkie will automatically broadcast a warning message, and the on-site protection officer will organize the on-site workers to immediately get off the road and switch to manual protection.

[0017] Furthermore, if the current working position mode is fixed, if the information sent by the walkie-talkie is received to confirm that all the working groups have left the road and the verification is successful, the method also includes judging whether all the on-site workers have entered the avoidance zone according to the positioning data of the positioning terminal. If not, an alarm message is sent to the positioning terminal.

[0018] Furthermore, the warning information is based on the route information, the registered work group work position and the location information of the on-site workers detected by the positioning terminal to determine whether the work group needs to get off the road or stop working, and then give a warning to get off the road or stop working.

[0019] When the present invention detects that the on-site workers need to get off the road or stop working, it not only sends warning information to the on-site workers; it also determines whether the information sent by the site to confirm that all the working groups have gotten off the road is received within the set time of sending the warning information; it determines whether the warning is lifted according to whether the confirmation is received and the verification result, and sends a stop message to the oncoming vehicle when the distance between the working position and the oncoming vehicle of this line is less than the set distance and not all of them have gotten off the road. It can be seen that the present invention can not only issue warning information, but also determine the off-road situation according to the feedback information after issuing it. If not all of them have gotten off the road, it will continue to issue warnings until all of them have gotten off the road, and it can also achieve emergency avoidance, thereby realizing closed-loop management of on-road operation safety protection, and fundamentally avoiding vehicle injury accidents.

[0020] The present invention also provides a railway on-track operation protection safety monitoring and management system.

[0021] It includes a positioning terminal for setting on the on-site workers and on-site protection personnel, a walkie-talkie for setting on the on-site protection personnel, an application terminal and a data processing center server, the application terminal and the data processing center server are connected in communication, and the application terminal and the data processing center server are also connected in communication with the positioning terminal and the walkie-talkie;

[0022] The data processing center server is used to generate an early warning message when it detects that the on-site workers need to get off the road or stop working, and the application terminal sends it to the positioning terminal and the intercom, and judges whether the information sent by the intercom to confirm that all the working groups have got off the road is received within the set time. If not, the early warning message is sent again until it is received or the distance between the working position and the oncoming vehicle of this line is less than the set distance. If it is received, it verifies whether all the oncoming vehicles have really got off the road according to the positioning data of the positioning terminal; if it is received but the verification is unsuccessful or it has not been received, then when the distance between the working position and the oncoming vehicle of this line is less than the set distance, it sends a stop message to the oncoming vehicle;

[0023] The positioning terminal is used to obtain the location information of the operating personnel, the walkie-talkie and the positioning terminal are used to issue an alarm based on the received warning information, and the walkie-talkie is also used to send information to the application terminal to confirm that all the operating groups have left the road based on the operation of the on-site protection personnel after receiving the warning signal.

[0024] Furthermore, the warning information sent to the walkie-talkie is realized through the communication method of the voice channel and / or the digital radio; the warning information sent to the positioning terminal is realized through the communication method of the 4G / 5G network and / or the digital radio.

[0025] Furthermore, the intercom is provided with a key module for personnel to operate, and the intercom sends information to the server of the signal building in the form of voice and / or key data.

[0026] Furthermore, the intercom includes an intercom button, a call module, a communication module, a data processing module, a modulator, a radio frequency circuit and at least one function button, one pin of the function button is connected to the IO pin of the data processing module, and the other pin is used to be grounded or connected to a power supply of a set voltage level. The data processing module is connected to the input end of the modulator, and is used to modulate the corresponding signal of the function button on the corresponding pin recognized by the data processing module into a modulated signal of a set format, and the output end is electrically connected to the radio frequency circuit, and is used to send the output modulated signal through the radio frequency circuit through the communication antenna.

[0027] Furthermore, the data processing center server also includes an alarm when it detects exceeding the protection distance, exceeding the specified working area or communication loss; exceeding the protection distance means that the on-site protection officer and the farthest on-site worker exceed the specified protection distance, and exceeding the specified working area means that the on-site worker exceeds the registered working position of the current work; communication loss refers to the interruption of communication between the walkie-talkie on the on-site protection officer and the application terminal.

[0028] Furthermore, the walkie-talkie is also used to automatically broadcast warning information in the event of a communication loss, and the on-site protection personnel organize on-site workers to immediately leave the road and switch to manual protection.

[0029] Furthermore, after receiving the information sent by the intercom confirming that all the working groups have left the road and the verification is successful, the application terminal also determines whether all the on-site workers have entered the avoidance zone based on the positioning data of the positioning terminal. If not, an alarm message is sent to the positioning terminal.

[0030] Furthermore, the data processing center server determines whether the work group needs to get off the road or stop working based on the route information, the registered work group work position and the location information of the on-site workers detected by the positioning terminal, and then gives an early warning to get off the road or stop working.

[0031] Furthermore, the application terminal is used to be set up in a signal tower, and includes a control computer and an application computer. The application computer is used to obtain registration information of the operation and send it to the data processing center server. The control computer is used to send the received warning information to the walkie-talkie and the positioning terminal.

[0032] The beneficial effects of the present invention are as follows: when the present invention detects that the on-site workers need to get off the road or stop working, it not only sends warning information to the on-site workers; it also determines whether the information sent by the site to confirm that all the working groups have gotten off the road is received within the set time of sending the warning information; it determines whether the warning is lifted according to whether the confirmation is received and the verification result, and sends a stop message to the oncoming vehicle when the distance between the working position and the oncoming vehicle of this line is less than the set distance and not all of them have gotten off the road. It can be seen that the present invention can not only issue warning information, but also determine the off-road situation according to the feedback information after issuing it. If not all of them have gotten off the road, it will continue to issue warnings until all of them have gotten off the road, and it can also achieve emergency avoidance, thereby achieving closed-loop management of on-road operation safety protection, and fundamentally avoiding vehicle injury accidents.

[0039] Implementation example of railway on-track operation protection safety monitoring and management system

[0040] The railway on-track operation protection safety monitoring and management system (SPE system for short) of the present invention includes a data processing center server for being installed in a bureau-level computer room, an application terminal for being installed in a signal tower (also called a driving room), an intercom installed on a field protection officer, and a positioning terminal installed on a work team member (including a field protection officer and a field operator), such as Figure 1 and Figure 2 As shown, the walkie-talkie is connected to the application terminal service communication through the base radio and voice transmission channel, and the positioning terminal is connected to the application terminal through the 4G / 5G network and the spread spectrum radio. The early warning information issued by the application terminal can be sent to the working group members through a variety of transmission channels, which improves the reliability of information transmission and enables the early warning information to be reliably sent to the working group members.

[0041] The positioning terminal set on the on-site operator adopts the Beidou positioning module. In addition to the Beidou positioning module, the present invention is also provided with an alarm module. The alarm mode of the alarm module can be voice, flash or vibration, or any combination thereof. For example, an alarm can be given through a voice player and multiple groups of flash lights to avoid the problem that the on-site operator cannot perceive due to noisy ambient sounds or strong light. The positioning terminal of this embodiment has two states: communication test mode and normal working mode, which can be switched by operating the corresponding buttons. The button FUN: long press the button to exit the communication test in the communication test mode; long press the button to enter the communication test in the working mode; single click the button to confirm the alarm in the working mode. Button ON / OFF: long press the button in the shutdown state to turn on the terminal; long press the button in the power-on state to shut down the terminal; after the communication test is successful, the on-site operator and the guard press the button to confirm. Long press the button ON / OFF to turn on the terminal, wait for the communication test to be completed, ensure that the equipment is in good working condition, and issue a voice prompt "test completed, please confirm" after completion. At this time, single click the button ON / OFF to confirm, and the terminal can work normally. When working, after receiving an alarm, the terminal will issue a corresponding alarm voice prompt accompanied by flashing lights. Click the FUN button to confirm the alarm and you can turn off the alarm prompt.

[0042] The intercom of the present invention adopts a DMR handheld intercom with data communication function. The intercom includes a shell. The outer surface of the shell is provided with an intercom button, a communication antenna, a function button, a channel switching knob button, a speaker amplifier, an indicator light and a display unit. The shell is provided with a call module, a data processing module, a modulator circuit and a radio frequency circuit. One pin of the function button is connected to the IO pin of the data processing module, and the other pin is used for grounding or connecting to a power supply of a set voltage level. In this embodiment, the other pin is grounded. The data processing module is connected to the input end of the modulator, which is used to modulate the signal corresponding to the function button on the corresponding pin recognized by the data processing module into a modulated signal of a set format. The output end is electrically connected to the radio frequency circuit, which is used to send the output modulated signal through the radio frequency circuit and then sent out by the communication antenna. Figure 3As shown, RF-IC is a radio frequency chip; RF-OUT is a radio frequency signal (wireless signal) output terminal; RF-IN is a radio frequency signal input terminal; FPE_Driver is a pre-driver amplifier chip; RF PA is a radio frequency power amplifier chip; ANT SW is an antenna switching switch; LPF is a low-pass filter; BPF is a band-pass filter; RF AMP is a radio frequency amplifier; AF OUT is an audio output; AF_AMP is an audio power amplifier; SPK is a speaker; SOC is a system-level chip; MIC_SW is a microphone switch; MIC is a microphone; LCD is a display screen; LED is an indicator light; BATT is a power supply / battery; LDO is a voltage regulator. The warning light is connected to the signal processing module and emits light to warn according to the instructions; the warning light has different light-emitting modes and light-emitting colors to warn the operator holding the walkie-talkie.

[0043] There is at least one function key located on the front of the outer shell, such as a confirmation key. In this embodiment, there are four function keys, namely a request key, a confirmation key, a pass key and a contact key. Each of the function keys is connected to an IO pin of the data processing module. The data processing module stores the content of the signal corresponding to each function key. The request signal corresponding to the request key is the request for the on-road work function; the confirmation signal corresponding to the confirmation key is the off-road avoidance, stop operation and communication contact; the pass signal corresponding to the pass key is the train passing the operation position reporting information; the contact signal corresponding to the contact key is the function of canceling the current operation position after pressing when the on-road operation is currently in progress; and it is used to press and execute the registration function of the current set position when there is no on-road operation.

[0044] The data processing module has the ability to identify and calculate. The data processing module of this embodiment is an MCU. The MCU reads whether each key is connected to the ground to determine whether the key is pressed. There are two signal working modes of the handheld intercom of this embodiment, including digital mode and analog mode. In the digital mode, when any function key is pressed, after being recognized by the MCU, the modulator is controlled to modulate the data into the format of 4FSK (4-quadrant frequency shift keying) and send it to the next level circuit. In the analog mode, after any function key is pressed and recognized by the MCU, the modulator is controlled to modulate the data into the format of GFSK (Gaussian frequency shift keying) and send it to the next level circuit, completing the process from pressing the key to the corresponding instruction data being modulated into a signal of the corresponding format, and finally transmitted by the power amplifier circuit (sound playback circuit) and antenna of the intercom. In addition, in order to realize the selection of two modulation circuits, the intercom is also provided with a switching button, one pin of the switching button is connected to the IO pin of the data processing module, and the other pin is used to be grounded or connected to a power supply of a set voltage level. Similarly, the application terminal is provided with a corresponding digital signaling demodulator and modulator to realize the interaction of digital signaling on the basis of realizing the voice interaction with the intercom.

[0045] like Figure 1 As shown, the application terminal in this embodiment includes a control computer, an application computer and a display screen, wherein the application computer is used to obtain the registration information of the operation and the confirmation information feedback from the intercom device, and the control computer is used to send the warning signal to the positioning terminal and the intercom through multiple channels, and control the communication radio used in the communication process. Among them, the control computer includes 2 units, which are hot standby for each other, namely the control host and the control standby; the application computer also includes 2 units, which are hot standby for each other, namely the application host and the application standby. When the control host fails, the control standby seamlessly takes over the software service and continues to ensure the normal application of the system; when the control standby fails, the control host seamlessly takes over the software service and continues to ensure the normal application of the system; when the control host fails, the software service is automatically switched from the control standby to the control host. When the application host fails, the application standby is automatically enabled, and the application standby automatically continues the data operation when it is interrupted to ensure the normal application of the system; when the application standby fails, the application host is automatically enabled, and continues to run to ensure the normal application of the system; when the application host fails, the application host is automatically enabled, and continues to run to ensure the normal application of the system. In addition, the hot standby computers share a monitor, a set of mouse and keyboard. When the primary and standby computers are automatically switched, the monitor, mouse and keyboard are automatically switched through the A_KVM switch.

[0046] The signal tower is also equipped with an analog-to-digital compatible DMR base station, a spread spectrum data transmission radio, a wireless train modulation radio, a BDS / GPSRTK base station, an industrial switch, and a microcomputer monitoring or train dispatching and command system acquisition interface. The control computer communicates with the walkie-talkie through the DMR base station, sends out warning information, and receives the operation information of the walkie-talkie buttons. The control computer solves the positioning data of the positioning terminal through the BDS / GPS RTK base station. The control computer communicates with the positioning terminal through the spread spectrum data transmission radio to send the warning information to the positioning terminal. The control computer obtains other information on the railway, such as route information, through the microcomputer monitoring or train dispatching and command system acquisition interface. The control computer also communicates with the train radio through the wireless train modulation radio to send parking information to the train. It is connected to the data processing center server through the industrial switch to obtain information judged by the data processing center server, including warning information, verification information, etc.

[0047] like Figure 1 and Figure 2As shown, the application terminals of each signal tower are connected to the data processing center server through the network. The data processing center server includes station terminals, bureau terminals, maintenance terminals, communication servers, voice databases, data servers, GIS servers, RTK differential data servers and NTP server data or functions connected through the railway local area network communication. The data processing center server can obtain route information based on the station terminals, solve the positioning data of the positioning terminal through the RTK differential data server, and obtain the geographic data of the operation position through the GIS server. The data processing center server determines whether the operation group needs to get off the road or stop the operation based on the route information, the registered operation position of the operation group and the location information of the on-site operation personnel detected by the positioning terminal, and then gives an early warning of getting off the road or stopping the operation.

[0048] The system works as follows:

[0049] The system divides the station and the section into working positions and safe areas for avoiding vehicles. According to the principles of the division of working positions and safe areas for avoiding vehicles and the characteristics of various professional on-road operations, the safety areas for avoiding vehicles are divided to meet the protection needs of different professional on-road operations. In principle, the safe areas for avoiding vehicles are set up on the shoulders of the section lines, on the outside of the station lines, or between tracks with a spacing of more than 5.0 meters between the station and the departure line, on bridge avoidance platforms, and in tunnel avoidance holes. It is strictly forbidden to avoid vehicles between the up and down main lines with a line spacing of less than 6.5 meters, inside the warning signs of the switch area, and in the tracks of the adjacent lines. For example, the safe areas for avoiding vehicles are generally located on the shoulders on both sides of the tracks. The distance from the main line is 3 meters, and the distance from the non-main line is 2.5 meters. Restricted avoidance areas can also be divided between tracks, and avoidance is also allowed under certain circumstances.

[0050] Before the work group goes on the road, it needs to register with the application computer of the application terminal. The registration information includes the location of the work group on the road and the equipment information worn by the work group members (including the intercom on the guard and the positioning terminal on the work group members). When the work group members arrive at the registered work location, the guard establishes a connection with the application terminal through the intercom, the positioning terminal starts the positioning function and establishes a communication connection with the application terminal through the digital radio (in this embodiment, the spread spectrum radio) and the 4G network, and the application terminal will determine whether the number of positioning terminals connected to the network is consistent with the number at the time of registration. If it is inconsistent, the application terminal will alarm, and the application terminal personnel will inform the guard through the intercom, and the guard will check and confirm on the spot.

[0051] The data processing center server determines whether the work group needs to get off the road or stop working based on the route information, the registered work group work position and the location information of the on-site workers detected by the positioning terminal, and then gives an early warning of getting off the road or stopping the work, and sends the early warning information to the application terminal through the network, which is then sent to the equipment (walkie-talkie and positioning terminal) carried by the members of the work group. Within the set time of sending the early warning information, the application terminal determines whether it has received the information sent by the on-site protection personnel through the walkie-talkie to confirm that all the work groups have gotten off the road; if not, an alarm is issued and the early warning information is sent again until it is received or the distance between the work position and the oncoming vehicle of this line is less than the set distance. If it is received, the data processing center server verifies whether all the vehicles have actually gotten off the road based on the positioning data of the positioning terminal; if it is received but the verification is unsuccessful or it has not been received, a stop message is sent to the oncoming vehicle when the distance between the work position and the oncoming vehicle of this line is less than the set distance.

[0052] This embodiment is aimed at a fixed working position mode. When the data processing center server determines that the working group is working on the track at the registered working position and a train on the same line or an adjacent line passes by, it sends an early warning message to the site. The warning information can be first sent to the walkie-talkie through two communication methods: voice channel and data transmission radio (DMR base station in this embodiment). After receiving the warning information through any channel, the walkie-talkie reminds the protection officer through voice, flashing lights or vibration. The flashing lights here can be set on the vest of the protection officer. The protection officer organizes the on-site workers to get off the road. After confirming that all of them have left the road, the protection officer operates the walkie-talkie to send information to the application terminal confirming that all the working groups have left the road. For example, the "confirmation button" on the walkie-talkie can be operated to send it to the application terminal through the data transmission radio, or a voice signal can be sent to the application terminal through the voice channel. If the application terminal does not receive the above confirmation information within the set time, such as 30s, the application terminal continues to send warning information to the walkie-talkie and sends the warning information to the positioning terminal of the same working group through the spread spectrum data transmission radio and 4G / 5G network, and controls the alarm module on the positioning terminal to work, so as to remind the on-site workers in various ways to avoid the protection officer's inadequate or untimely notification, so that the on-site workers can supervise each other. As another implementation method, the application terminal can also send the warning information to the intercom and each positioning terminal at the beginning, and send the warning through multiple communication methods to further improve the level of protection. After the application terminal sends the warning information to the positioning terminal in the same operation group through the spread spectrum data transmission radio, the positioning terminal can issue a voice message "train passing, get off the road to avoid the car" or "adjacent line train passing, stop working", and the vest flashes yellow light to remind people to get off the road or stop working.

[0053] For example, after the warning information is issued, a confirmation reminder voice is sent to the handheld intercom of the on-site protection personnel every 15 seconds. After two consecutive reminder voices, if the on-site protection personnel do not confirm the next road by pressing the handheld intercom button, the indoor application computer will issue a sound and screen pop-up alarm. At the same time, the spread spectrum data transmission radio sends instructions to the SPE positioning terminal in the same operation group registered on site. The SPE positioning terminal issues a voice "Not all members of the operation group have left the road", and the vest flashes yellow light to remind the members of the operation group that they have not left the road as required.

[0054] When the on-site protection officer has confirmed the evacuation by pressing the intercom button, the data processing center server verifies whether all the positioning terminals have evacuated the track based on the location information of each positioning terminal. When the verification fails or the above confirmation information is not received, the application terminal continues to send early warning information to the positioning terminals in the same working group through the spread spectrum data transmission radio and 4G / 5G network until the set distance is reached. The set distance in this embodiment refers to the protection section before the train enters the registered working position, indicating that the train has not evacuated the track in time.

[0055] When the train fails to get off the track in time and enters the protection section before the registered working position, the application terminal automatically calls the wireless train dispatching station three times "xx times, stop immediately" to stop the train and ensure safety.

[0056] When the application terminal receives the confirmation information and the data processing center server verifies successfully, it means that all the workers in the group have left the road. Since the fixed operation position module is targeted in this embodiment, after confirming that all the operation groups have left the road, in order to further improve the safety of protection, it is also necessary to ensure whether all the operation groups have entered the avoidance zone. At this time, the data processing center server determines whether all the on-site workers have entered the avoidance zone based on the positioning data of the positioning terminal. If not, the application terminal sends an alarm message to the positioning terminal.

[0057] In addition, the data processing center server is also used to detect the protection distance, communication status and whether it exceeds the specified operating area. It will issue an alarm when it detects that the protection distance is exceeded, the specified operating area is exceeded, or the communication is lost.

[0058] The data processing center server dynamically calculates the distance between the work group members based on the positioning data of the positioning terminal. When the on-site protection officer and the farthest worker exceed the specified protection distance, the yellow cursor on the control application computer interface flashes as an alarm reminder. At the same time, a command is sent to the positioning terminal in the same work group registered on site through the spread spectrum data transmission radio. The positioning terminal issues a voice message "Beyond the protection distance, please pay attention", and the vest where the positioning terminal is located flashes yellow to remind the work group members that they have exceeded the protection distance.

[0059] The system also supports simultaneous registration of multiple work positions. The intercom switches the registered work position of the current work. When a member of the work group exceeds the registered work position of the current work, the data processing center server controls the application computer interface with a flashing yellow cursor to remind. At the same time, the spread spectrum data transmission radio sends instructions to the SPE positioning terminal in the same work group registered on site. The SPE positioning terminal issues a voice message "Beyond the working range, please pay attention" and the vest flashes yellow to remind the work group members that they have exceeded the working range.

[0060] In order to detect the communication status in real time, the application computer of the application terminal sends heartbeat data to the registered SPE handheld intercom through the DMR base station every set time (for example, 4 minutes). The SPE handheld intercom broadcasts "Please confirm the communication contact". The on-site protection personnel should press the confirmation key on the SPE handheld intercom as a response within 8 seconds. If the application computer does not receive a response confirmation within 8 seconds, the system will send heartbeat data again every 8 seconds, up to 3 times. If the on-site protection personnel do not respond, it is considered to be lost; when there is no response, the application computer interface of the application terminal will issue a sound and screen pop-up window alarm. In the lost state, the positioning terminal will issue a voice "Communication lost, get off the road immediately", and the vest will flash yellow light; if the heartbeat is interrupted, the intercom will automatically broadcast "Communication lost, get off the road immediately", and the on-site protection personnel will organize the operating personnel to get off the road immediately and switch to manual protection.

[0061] In order to facilitate the on-duty personnel to intuitively understand the actual location of the operators, the system can display the real-time location of the operators on the display screen, and the location information is superimposed on the GIS map and the SPE system station diagram. The real-time display of the operator's location on the GIS map, such as Figure 4 As shown, it is refreshed every second and the trajectory can be played on demand:

[0062] (1) Select time, unit, work group, and operator to playback the trajectory of the personnel who meet the selected conditions;

[0063] (2) Enter the real-time tracking interface according to the site, display the current location of the work team, and the protection personnel and the work personnel are displayed with different icons;

[0064] (3) When you click on the icon of the person being tracked, the relevant information of the person is displayed, including key information such as ID and location.

[0065] The above system is aimed at the protection of the fixed working position mode. The method for the inspection operation mode is similar to that of the fixed working position mode. The difference is: first, when generating early warning information, the data processing center server determines whether the inspection personnel have invaded the area within 2 meters of the center line of the line that has been processed. When it is detected that the inspection personnel are less than two protection sections away from the train and enter the area within 2 meters of the center line of the line, the data processing center server generates corresponding early warning information; second, because it is an inspection operation, the operation range is relatively wide and it is impossible to set an avoidance zone. Therefore, there is no avoidance zone in this mode. It is only necessary to ensure that all inspection personnel get off the road.

[0066] Implementation method for monitoring and managing railway on-track operation protection safety

[0067] The monitoring method of this embodiment first sends an early warning message to the on-site workers when it is detected that the on-site workers need to get off the road or stop working; then, within the set time of sending the early warning message, the application terminal determines whether the information sent by the on-site protection personnel through the intercom to confirm that all the working groups have gotten off the road is received; if not received, an alarm is issued and the early warning message is sent again until it is received or the distance between the working position and the oncoming vehicle of this line is less than the set distance. If received, it is verified whether all of them have actually gotten off the road according to the positioning data of the positioning terminal; if received but the verification is unsuccessful or it has not been received, a stop message is sent to the oncoming vehicle when the distance between the working position and the oncoming vehicle of this line is less than the set distance. The specific implementation process of this method has been described in detail in the system embodiment, and will not be repeated here.
