Description

Technical Field

[0001] The utility model relates to the field of railway trackside operation safety protection, in particular to a railway trackside operation safety protection system. Background Art

[0002] Construction and maintenance of trackside equipment must be performed within designated timeframes. This can lead to the following safety hazards: 1. Station security personnel must maintain clear communication with on-site security personnel based on the train schedule and constantly confirm the blocking and release of trains. Failure to maintain coordinated control at the prescribed intervals between station security personnel and on-site security personnel can hinder both parties' timely understanding of train operations, potentially leading to safety incidents. 2. Station duty personnel may illegally release trains, drivers may illegally unlock and overtake, or other personnel may misinterpret dispatching orders, leading to trains entering blocked areas. While various safety devices are currently available for trackside operations, there is still no coordinated control and protection system. While time reminders can remind on-site security personnel to check in with station security personnel at the designated time, these reminders are not synchronized with intercom time. While train approach alarms can sense trains, their short range means that personnel often have no time to evacuate immediately when the alarm sounds. To ensure safety during trackside operations, it is necessary to design a safety and protection system for trackside operations. Summary of the Invention

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0023] For example, see Figures 1 to 5 As shown in the figure, the railway trackside operation safety protection system includes:

[0024] Walkie-talkie 1, carried by the on-site security officer and used to communicate with the station security officer;

[0025] The joint control trigger 2 is installed on the intercom 1 and is used to send a joint control signal to the joint control prompter 3 and the evacuation prompter 4. The joint control signal includes a joint control trigger signal and a joint control interrupt signal;

[0026] The joint control prompter 3 is carried by the on-site security personnel and is used to receive the joint control signal. When the joint control interruption signal is received, the timing is started. When the joint control interruption signal exceeds a first predetermined time, the joint control prompt alarm is issued. When the joint control trigger signal is received, the timing is stopped and reset to zero.

[0027] An evacuation reminder 4 is carried by on-site workers and is used to receive the joint control signal and the evacuation alarm signal. When the joint control interruption signal is received, the timer starts counting. When the joint control interruption signal exceeds the second predetermined time or the evacuation alarm signal is received, the evacuation alarm is issued. When the joint control trigger signal is received, the timer stops counting and returns to zero.

[0028] The laser ranging alarm 5 is set at both ends of the trackside operation track to measure the distance of the train, trigger a danger alarm according to the preset alarm distance, and trigger an evacuation alarm signal.

[0029] In this embodiment, the second predetermined time is greater than the first predetermined time.

[0030] like Figure 2 As shown, the joint control trigger 2 includes a TXS12 transmitter module, the intercom button of the intercom 1 is connected to the IN pin and GND pin of the TXS12 transmitter module, the intercom 1 is powered by the TXS12 transmitter module, and DC9V is the battery on the intercom.

[0031] In this embodiment, the laser ranging alarm 5 is also provided with a no-entry signal light.

[0032] During use, the intercom 1, the joint control trigger 2, and the joint control prompter 3 are all carried by the on-site protection officer, and the protection distance of the protection officer is implemented in accordance with regulations; the evacuation prompter 4 is carried by the on-site operating personnel; the laser ranging alarm 5 is set at both ends of the trackside operation track, and is set by the on-site operating personnel in accordance with regulations when working on the track. The no-entry signal light is always in working state (red) during work; the on-site protection officer and on-site operating personnel must keep the equipment they carry in the power-on state during work. When the evacuation prompter 4 issues an evacuation alarm (the alarm method is sound and light alarm), the on-site operating personnel must evacuate the work site to a safe area. If it is a false alarm and the false alarm is eliminated and safety is confirmed, they can enter the work site to perform operations.

[0033] For example, the on-site security officer conducts a safety joint control with the station security officer via intercom every 5 minutes, with the first scheduled time being 4 minutes and 15 seconds and the second scheduled time being 4 minutes and 45 seconds: when the joint control prompter 3 receives the joint control interruption signal, it starts timing. When the joint control interruption time reaches 4 minutes and 15 seconds, the joint control prompter 3 issues a joint control prompt alarm. The joint control time is synchronized with the call time of the intercom 1. When the intercom key is pressed, that is, the joint control trigger 2 sends a joint control trigger signal, the joint control prompter 3 receives the joint control trigger signal, and then no alarm is given. The joint control prompter 3 stops timing and returns to zero.

[0034] When the evacuation reminder 4 receives the joint control interruption signal, it starts timing. When the joint control interruption time reaches 4 minutes and 45 seconds and the on-site protection officer still has not conducted joint control with the on-site protection officer, the evacuation reminder 4 issues an evacuation alarm, prompting the on-site workers to evacuate the work site urgently and move to a safe area urgently. When the intercom button is pressed, the joint control trigger 2 sends a joint control trigger signal, and the evacuation reminder 4 receives the joint control trigger signal, then no alarm is issued, and the evacuation reminder 4 stops timing and returns to zero.

[0035] When a train illegally enters the on-site operation track, the danger alarm 5 measures the distance to the train through the laser ranging alarm 5. When the train enters the alarm distance (the alarm distance is set according to needs, and the general alarm distance is 800 to 2000 meters within the operation safety range), a danger alarm is issued (the alarm mode is a sound alarm and a flashing indicator light alarm) to prompt the driver to take emergency braking measures, thereby avoiding the occurrence of safety accidents. At the same time, the evacuation reminder 4 is triggered to issue an evacuation alarm, prompting on-site workers to evacuate the operation site urgently and move to a safe area.

[0036] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended that all changes that fall within the meaning and range of equivalents of the claims are included in the present invention. Any reference signs in the claims should not be construed as limiting the claim to which they relate.
