Description

Technical Field

[0001] This application relates to the field of railway technology, and in particular to a safety early warning method, system, computer equipment, readable storage medium, and program product for railway tunnels. Background Technology

[0002] The safe operation of railway tunnels relies on regular inspections and necessary temporary construction and maintenance. However, the enclosed and narrow environment of tunnels presents a serious challenge to the safety management of workers.

[0003] In traditional technology, trains are usually equipped with onboard communication equipment, and the communication tools used by the workers are also used by the control center. Based on the train's position reported by the onboard communication equipment and the position information reported by the workers through their communication tools, the control center notifies the staff of train information and issues safety warnings.

[0004] However, tunnels often contain communication blind spots. When a train enters a tunnel, its onboard communication equipment and the communication tools held by the workers may experience severe signal attenuation or even complete loss due to the shielding of electromagnetic waves by the tunnel structure. This makes it difficult for the control center to provide effective safety warnings, resulting in low operational safety. Summary of the Invention

[0017] In one embodiment, the central control console sends control signals to the target train based on the number of people in the tunnel and the number of pagers sending the safety signals, including:

[0018] If the number of people in the tunnel is equal to the number of pagers that sent the safety signal, the central control console sends a first control signal to the target train. The first control signal is used to instruct all people in the tunnel to move to a safe location.

[0019] If the number of people in the tunnel is less than the number of pagers that sent the safety signal, the central control console sends a second control signal to the target train. The first control signal is used to indicate that not all people in the tunnel have moved to a safe position.

[0020] In one embodiment, a safety button is provided at the preset safe location. After detecting that the target person has reached the preset safe location, the pager sends a safety signal to the wired signal box, including:

[0022] In one embodiment, the system further includes a security warning device; the method further includes:

[0023] In response to the warning signal, the base station sends a control signal to the security warning device, the control signal being used to activate the security warning device.

[0024] Secondly, this application also provides a safety early warning system for railway tunnels, the safety early warning system including a pager, a wired signal box, a central control console, and a base station, wherein:

[0025] The pager is used to send the location signal of the target person to the wired signal box;

[0026] The wired signal box is used to transmit the location information of the target person to the central control console via the base station in response to the location signal;

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0043] This application provides a safety early warning method for railway tunnels, which can be applied to a safety early warning system. For example... Figure 1The diagram illustrates the application environment of a railway tunnel safety early warning method according to an embodiment of this application. It includes a pager, a wired signal box, a central control console, and a base station (such as a signal base station). It is understood that this application environment may also include other optional devices, such as safety early warning devices, safety buttons, and gates. The pager can be a device with vibration and sound modules, used to receive signals from the wired signal box and send position signals to it. The wired signal boxes can be equidistantly arranged within the tunnel, and there can be multiple wired signal boxes. They can be wiredly connected to a base station outside the tunnel to receive wired signals from the base station and to wirelessly receive and transmit signals to the pager. The central control console can be based on the Chinese Train Control System (CTCS) and is used to communicate with the base station and the railway train positioning system. The central control console is a system that ensures the safe and rapid operation of trains. The CTCS includes onboard equipment and ground equipment, and its main function is to control train intervals and speed. Base stations can be located outside the tunnel to receive signals from or send signals to the central control station, as well as to transmit signals to wired signal boxes within the tunnel via wired connections. As a form of radio station, a base station is a radio transceiver that facilitates information exchange between a communication exchange center and mobile terminals. It operates within a certain radio coverage area, ensuring that mobile terminals and other wireless devices can connect to the network and communicate. Safety warning devices can be terminal devices with alerting functions. Alert methods may include, but are not limited to, lights, sounds, and vibrations. In this embodiment, the safety warning device can be a signal light strip within the tunnel. The signal light strip can be laid along the tunnel, running through the entire tunnel, and has at least three flashing colors, such as red, green, and yellow. Additionally, entrance and exit gates can be installed at the tunnel's personnel entrances and exits. These gates can count the number of people entering the tunnel. Devices for storing pagers can be installed at these gates; the gate opens only after a pager is retrieved, allowing one person to enter. The storage slots for pagers contain charging components; placing a pager into its corresponding slot allows it to charge. When exiting the gate, personnel must return the pager by placing it in the pager return device. The gate opens only after a pager is returned, allowing one person to pass. Each train can be equipped with a GPS (Global Positioning System) that transmits its real-time location and speed to the central control station and receives signals from the central control station. It can record not only the train's location information but also its speed and other train information.

[0044] The safety early warning method for railway tunnels provided in this application will be described in detail below, with specific implementation methods as an example. Figure 2 As shown, the method includes the following steps:

[0045] Step 202: The pager sends the location signal of the target person to the wired signal box.

[0046] In this embodiment, when a target person enters the tunnel, they need to take and wear a pager. Wired signal boxes can be installed in the tunnel at preset intervals. The pager can send location signals in real time, and at least two wired signal boxes near the pager can receive the location signals sent by the pager.

[0047] Step 204: In response to the location signal, the wired signal box sends the location information of the target personnel to the central control console via the base station.

[0048] In this embodiment, after the wired signal box detects a location signal, it can transmit the location information of the target person to the base station via a wired connection, and then the base station sends it to the central control console. The location signal can be the Wi-Fi signal received by the wired signal box from the pager, and the location information can be the location signal received by the wired signal box from the pager.

[0049] In one example, when the target personnel enter the tunnel, they need to pass through the tunnel gate and each person takes a pager at the gate; otherwise, the gate cannot be opened. The target personnel enter the tunnel carrying the pagers. For example, three target personnel enter the tunnel, and the pagers they wear are N1, N2, and N3 respectively. Wired signal boxes are set at equal intervals in the tunnel, for example, signal boxes are H1, H2, H3, H4, H5, H6, H7, H8, H9, and H10, with a 100-meter interval between every two wired signal boxes.

[0050] When pager N1 is located between wired signal boxes H1 and H2, the location signal sent by pager N1 is received by the nearest wired signal boxes H1 and H2 respectively. The wired signal boxes H1 and H2 then transmit the location signal of pager N1 to the base station via wired connection. The base station then transmits the location signal of pager N1 to the central control console.

[0051] When pager N2 is located between wired signal box H2 and wired signal box H3, the position signal sent by pager N2 is received by the nearest wired signal box H2 and wired signal box H3 respectively. The wired signal boxes H2 and H3 then transmit the position signal of pager N2 to the base station via wired connection. The base station then transmits the position signal of pager N2 to the central control console.

[0052] When pager N3 is located between wired signal box H3 and wired signal box H4, the location signal sent by pager N3 is received by the nearest wired signal box H3 and wired signal box H4 respectively. The wired signal boxes H3 and H4 then upload the location signal of pager N3 to the base station via wired connection. The base station then sends the location signal of pager N3 to the central control console.

[0053] Step 206: The central control console determines the location information of the target personnel based on the location information, sends the location information to the target train, determines the predicted time when the target train will arrive at the location of the target personnel, and sends an early warning signal to the base station according to the predicted time.

[0054] In this embodiment, the central control console can respond to location information and use a preset positioning algorithm to locate the target person, thereby obtaining the target person's location information. The positioning algorithm can be either triangulation or fingerprint positioning; this embodiment is not limited to either. Taking triangulation as an example, the central control console can pre-store the coordinate information of each wired signal box and the coordinate information of the base station. After receiving location information, it can obtain the coordinate information of the two wired signal boxes that sent the location information, as well as the coordinate information of the base station. Then, based on the location information and the obtained coordinate information, it uses a triangulation algorithm to calculate the location information of the pager, i.e., the location information of the target person. The location information can be RSSI (Received Signal Strength Indicator), and the positioning information can be coordinate values.

[0055] After calculating the location information of the target personnel, the central control console can send this information to the target train. Simultaneously, it can determine the predicted time for the target train to reach the target personnel, and then send an early warning signal to the base station based on the predicted time. Specifically, based on the target personnel's location information, the distance *x* from the tunnel entrance can be determined. Then, based on distance *x*, the target train's speed *S*, and the target train's distance from the tunnel *d*, the time *T* required for the target train to reach the target personnel's location inside the tunnel can be calculated. The calculation formula is:

[0056]

[0057] In one example, the train speed is 120 km / h, the distance between the worker's position inside the tunnel and the tunnel entrance is 5 km, and the distance between the train and the tunnel is 15 km. According to the above formula, T equals 10 min, that is, there is a distance of 20 km between the worker and the train, and the worker has 10 minutes to take precautions.

[0058] Step 208: In response to the warning signal, the base station sends warning information to the pager through the wired signal box so that the pager can provide a warning to the target person.

[0059] In this embodiment, in response to a warning signal, the base station can send warning information to the pager via a wired signal box. Upon receiving the warning information, the pager can use a preset prompting method to alert the target personnel. This prompting method may include, but is not limited to, vibration, sound, and flashing lights. For example, when T equals 10 minutes, the central control console sends a signal to the base station, which then sends a signal indicating the train's approach to the wired signal box via a wired connection. The wired signal boxes, equidistantly located within the tunnel, wirelessly contact the pager, which receives the signal and vibrates and sounds.

[0060] By adopting the above solution, target personnel can be located and warned through wired signal boxes and base stations. This can effectively solve the problem of the inability to locate and warn personnel due to communication blind spots caused by vehicle-mounted communication equipment and communication tools held by operators, thus improving operational safety.

[0061] Optionally, sending an early warning signal to the base station based on the predicted time includes: determining the security risk level based on the predicted time; and sending an early warning signal to the base station based on the security early warning strategy corresponding to the security risk level.

[0062] In this embodiment, the central control console can pre-store the mapping relationship between prediction time and security risk level. The longer the prediction time, the lower the security risk level; conversely, the shorter the prediction time, the higher the security risk level. The central control console can determine the matching security risk level based on the prediction time, and then send a warning signal to the base station according to the security warning strategy corresponding to the security risk level. The base station can then send warning information to relevant devices according to the prompting strategy corresponding to the warning signal. For higher security risk levels, the number of relevant devices will be greater, and the prompting methods indicated by the warning information will be more numerous and obvious. In one example, if the security risk level is low, the pager and the tunnel signal light strip's first-level warning will be activated to determine the train distance; if the security risk level is medium, the pager and the tunnel signal light strip's second-level warning will be activated to determine the train distance; and if the security risk level is high, the pager and the tunnel signal light strip's third-level warning will be activated to issue an emergency alarm.

[0063] By adopting the above scheme, different methods can be used for early warning according to different risk levels, which can effectively improve the accuracy and effectiveness of early warning, thereby improving operational safety.

[0064] Optionally, in the event of a loss of signal from the railway train positioning system, i.e., when the train passes through tunnels continuously, or in situations with poor communication conditions such as in special areas or under special weather conditions, the predicted time for the target train to reach the tunnel entrance can be calculated using the last transmitted position of the target train positioning system and the maximum speed of the target train's current section of the track. The calculation formula is as follows:

[0065]

[0066] The maximum speed of the target train on the current section of the track is S1, the distance between the train and the tunnel entrance is d1, d1 is determined based on the last location sent by the target train positioning system and the location of the tunnel entrance, and T1 is the predicted time for the target to reach the tunnel entrance.

[0067] For example, if the maximum speed of the train on this section is 80 km / h and the distance between the train and the tunnel entrance is 50 km, according to the above formula, the time T1 for the train to reach the tunnel entrance is 37.5 minutes. Then, the train will pass through the tunnel after 37.5 minutes. When T1 equals 30 minutes, the pager and the tunnel signal light strip can be activated to determine the train distance. The pager will vibrate intermittently, the sound module will broadcast a time reminder, and the tunnel signal light will flash three times. When T equals 20 minutes, the pager and the tunnel signal light strip can be activated to determine the train distance. The pager will vibrate intermittently, the sound module will broadcast a time reminder, and the tunnel signal light will flash twice. When T equals 10 minutes, the pager and the tunnel signal light strip can be activated to issue an emergency alarm. The pager will vibrate and sound continuously, and the tunnel signal light will switch to red and flash continuously.

[0068] Optionally, the method also includes: after detecting that the target personnel have reached the preset safe position, the pager sends a safety signal to the wired signal box, and the wired signal box sends the safety signal to the central control console through the base station; the central control console sends a control signal to the target train based on the number of people in the tunnel and the number of pagers that sent the safety signal.

[0069] In this embodiment, it is also possible to monitor whether the target personnel have reached a preset safe position. Optionally, monitoring equipment deployed at the preset safe position can monitor whether the target personnel have reached the preset safe position. After detecting that the target personnel have reached the preset safe position, the monitoring equipment can send a preset command to the pager to trigger the pager to send a safety signal to the wired signal box. The wired signal box can then send the safety signal to the central control console via the base station. The central control console can send control signals to the target train based on the number of target personnel entering the tunnel and the number of pagers sending safety signals.

[0070] By adopting the above scheme, it is possible to effectively monitor whether the target personnel in the tunnel have reached a safe position to avoid danger, and control the operation of the target train according to the arrival situation, thereby improving safety.

[0071] Optionally, the central control console sends a control signal to the target train based on the number of people in the tunnel and the number of pagers sending safety signals. This includes: if the number of people in the tunnel equals the number of pagers sending safety signals, the central control console sends a first control signal to the target train, which instructs all personnel in the tunnel to move to a safe location; if the number of people in the tunnel is less than the number of pagers sending safety signals, the central control console sends a second control signal to the target train, which instructs that not all personnel in the tunnel have moved to a safe location.

[0072] In this embodiment, if the number of people in the tunnel equals the number of pagers sending safety signals, the central control console sends a first control signal to the target train. This first control signal instructs all personnel in the tunnel to move to a safe position. Upon receiving the first control signal, the target train can maintain its speed and pass through the tunnel. If the number of people in the tunnel is less than the number of pagers sending safety signals, the central control console sends a second control signal to the target train. This second control signal instructs that not all personnel in the tunnel have moved to a safe position. Upon receiving the second control signal, the target train slows down and passes through the tunnel.

[0073] In one example, because a tunnel is a relatively enclosed space, airflow cannot flow as freely as in an open environment. This means that changes in airflow caused by train movement cannot be replenished in a timely manner, leading to more pronounced pressure differences and velocity variations. Therefore, safety locations are necessary. Specifically, safety locations can be set between every two sets of wired signal boxes within the tunnel, and monitoring equipment can be installed at these safety locations.

[0074] Using the above scheme, if the number of people in the tunnel is equal to the number of pagers sending safety signals, the target train will maintain its speed as it passes through the tunnel to improve operational efficiency; if the number of people in the tunnel is less than the number of pagers sending safety signals, the target train will slow down as it passes through the tunnel to ensure the safety of the personnel.

[0075] Optionally, a safety button is installed at a preset safe location. After detecting that the target person has reached the preset safe location, the pager sends a safety signal to the wired signal box, including: sending a safety signal to the wired signal box when the pager detects a proximity signal from the safety button.

[0076] In this embodiment of the application, a safe location can be set between every two sets of wired signal boxes in the tunnel, and a safety button is added to the safe location. After receiving the warning prompt, the target personnel walk to the safe location, and when the pager detects the close proximity signal of the safety button, it sends a safety signal to the wired signal box.

[0077] Optionally, after a worker moves to a safe location, they can press the pager against the safety button to cancel its vibration and sound, triggering the safety button to transmit a safety signal to the base station via a wired signal box. The base station then sends the safety signal to the central control console, which can count the number of pagers that have sent safety signals as the number of people who have moved to a safe location.

[0078] By adopting the above solution, the accuracy of moving the target personnel to a safe location can be improved, thereby enhancing the accuracy of the judgment made by the central control console and thus improving operational safety.

[0079] like Figure 3 As shown in the figure, this application provides an example of a safety early warning method for railway tunnels, including the following steps:

[0080] Step 301: In response to the pager retrieval operation, the gate opens and the number of people entering the tunnel is recorded.

[0081] Step 302: The pager sends the location signal of the target person to the wired signal box.

[0082] Step 303: In response to the location signal, the wired signal box sends the location information of the target personnel to the central control console via the base station.

[0083] Step 304: The central control console determines the location information of the target personnel based on the location information, sends the location information to the target train, and determines the predicted time for the target train to reach the target personnel.

[0084] Step 305: If the predicted time is less than a preset threshold, the central control console sends an early warning signal to the base station.

[0085] Step 306: The base station sends a warning message to the pager through the wired signal box.

[0086] Step 307: The pager provides a warning to the target person through vibration and sound, prompting the target person to move to the preset safe location as soon as possible, and the pager is placed against the safety button to cancel its vibration and sound.

[0087] Step 308: The safety button transmits the safety signal to the base station via the wired signal box. The base station then sends the safety signal to the central control console. The central control console can count the number of pagers that send the safety signal, which is the number of people who have moved to a safe location.

[0088] Step 309: The central control console counts the number of people who have moved to a safe location.

[0089] Step 310: If the number of people in the tunnel is equal to the number of pagers sending safety signals, the central control console sends the first control signal to the target train.

[0090] Step 311: After receiving the first control signal, the target train can maintain its speed and pass through the tunnel.

[0091] Step 312: If the number of people in the tunnel is less than the number of pagers sending safety signals, the central control console sends a second control signal to the target train.

[0092] Step 313: After receiving the second control signal, the target train slows down and passes through the tunnel.

[0093] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.
