Description

Technical Field

[0001] This invention relates to the field of railway safety technology, specifically to a safety protection terminal device and protection method for railway operation sites. Background Technology

[0002] The "Construction Operation Safety Protection Auxiliary System" is a personal safety protection auxiliary equipment designed specifically for railway professional operations. It is applicable to the on-track operation scenarios of various professionals on operating lines. It aims to further improve operational safety on the basis of the existing protection system through an automated early warning and information transmission mechanism, reduce the workload of station liaisons, and ensure that on-site operation teams can obtain key safety information in a timely and effective manner, thereby strengthening the self-protection and self-control effect of the operation teams. The system's hardware is mainly divided into fixed equipment for data acquisition and terminal equipment.

[0003] The terminal equipment includes handheld terminals for safety personnel and handheld terminals for work supervisors. The handheld terminal for safety personnel is carried by the on-site safety personnel and is used to receive vehicle alarms and report the status of the work group to the indoor office. It can provide functions such as vehicle arrival prediction, automatic playback of confirmed alarm voice messages, and confirmation of alarm reception, completion of vehicle avoidance, and completion of track entry. The handheld terminal for work supervisors is carried by the work supervisors and is used to receive vehicle alarms. When it is necessary to organize vehicle avoidance, it will emit flashing alarm lights. It can provide functions such as vehicle arrival prediction, automatic playback of confirmed alarm voice messages, and automatic and manual switching of alarm lights.

[0004] However, when current railway operation site terminals are used by on-site personnel, they need to be fixed to protective clothing, waist belts, or shoulder straps with back clips. The function keys and warning light panels of the terminal are all facing away from the personnel, creating blind spots. This not only makes operation inconvenient but also makes it difficult for personnel to notice the flashing warning lights in time. At the same time, noise at the operation site can also affect the reception of voice-playing information. Therefore, a safety protection terminal device and protection method for railway operation sites are proposed. Summary of the Invention

[0005] The purpose of this invention is to address the problems that current railway work site terminals have function keys and warning light panels facing away from workers, creating blind spots, making operation inconvenient, and making it difficult for workers to notice flashing warning lights in time. Additionally, noise at the work site can affect the reception of voice-playing information. This invention provides a safety protection terminal device and protection method for railway work sites.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution: A safety protection terminal device and protection method for railway operation sites includes a protective handheld terminal. The top of the handheld terminal has a display screen for displaying optical warning signals, a speaker hole for outputting acoustic signals, and two control buttons for interaction. One side of the handheld terminal has a rotatable power knob for controlling the power switch and the volume of the speaker hole. Another side of the handheld terminal has a function key for pre-set functions. The other side of the handheld terminal has a charging port and an external port. An external device connection cable is inserted into the external port. One side of the handheld terminal has a mirror frame with two dustproof lenses fixedly mounted on it. A bone conduction headset is fixedly mounted at one end of the mirror frame, and one end of the external device connection cable is fixedly mounted on the bone conduction headset. A laser generator is fixedly mounted on the side wall of the mirror frame, located between the two dustproof lenses, with its two output ends facing the two dustproof lenses respectively. A self-adhesive wristband is fixedly mounted at the bottom of the handheld terminal.

[0007] Furthermore, a self-adhesive arm ring is provided between the protective handheld terminal and the mirror frame, and a drawstring is fixedly installed on one side of the self-adhesive arm ring, with the external device connection cable located inside the drawstring.

[0008] Furthermore, a clip is attached to the self-adhesive arm ring, and a signal repeater is fixedly installed on one side of the clip. An enhanced antenna is inserted into the top of the signal repeater. Antenna holes are opened on one side of both the protective handheld terminal and the signal repeater. An antenna connecting wire is inserted into the inside of the antenna hole on the signal repeater. One end of the antenna connecting wire passes through the gathering strap and is inserted into the inside of another antenna hole.

[0009] Furthermore, the bottom end of the external device connection cable and both ends of the antenna connection cable are movably fitted with fastening thread caps. The protective handheld terminal has first fastening screw rings fixedly installed on both sides and one side of the signal repeater. The positions of the three first fastening screw rings correspond to the positions of the external hole and the two antenna holes, respectively. The three fastening thread caps are screwed onto the three first fastening screw rings.

[0010] Furthermore, a second fastening screw ring is fixedly installed on one side of the protective handheld terminal, the first fastening screw ring is located inside the second fastening screw ring, a storage screw is screwed onto the second fastening screw ring, one end of the storage screw has a through hole, and the antenna connection line is located inside the through hole.

[0011] Furthermore, a transparent protective cover is fixedly sleeved on one end of the storage screw cylinder, the transparent protective cover is located on the top of the protective handheld terminal, and a hanging groove is opened on the other side of the transparent protective cover. A hanging rod is fixedly installed on the side of the protective handheld terminal away from the storage screw cylinder, and the hanging rod is located inside the hanging groove.

[0012] Furthermore, multiple storage hooks are fixedly installed on the inner wall of the transparent protective cover.

[0013] A safety protection method for railway work sites includes the following steps: S1. Wearing: Twist the storage screw to remove the transparent protective cover, then pull out the booster antenna, remove the antenna connection cable, and pass one end of the antenna connection cable through the through hole and plug it into the protective handheld terminal. Pass the other end through the strap and plug it into the signal repeater. Reinstall the storage screw and transparent protective cover, then plug the booster antenna into the signal repeater. After that, pass one end of the external device connection cable through the strap and plug it into the external hole. Then, put the self-adhesive arm loop on your arm, put the self-adhesive wrist strap and the protective handheld terminal on your wrist, and finally put on the glasses frame. S2. Power on: Turn the power knob clockwise to turn on the power and adjust it to a suitable volume. At this time, the system will perform a self-test until the speaker plays a voice message indicating successful power-on. S3. Voice Alarm and Confirmation: During normal operation, if an alarm is triggered, the handheld protection terminal will automatically play the voice message repeatedly through the speaker hole. After receiving the alarm message, the protection operator will press the corresponding function key according to the route to confirm whether it is up or down. If the wrong confirmation button is pressed or the function key is not pressed in time within the content playback frame, the alarm message will continue to be played repeatedly until the correct button is pressed, or if a more urgent alarm is triggered, the alarm message will be played continuously. S4. Confirmation of Train Avoidance Completion: Depending on the train operation, if it is necessary to go off track to avoid a train or to stop the operation by pulling the rope in place, after the train avoidance is organized, the safety officer presses the control button to report the information "Train Avoidance Completed". The status of the work group will be updated to "Train Avoidance in Progress" in real time on the tablet interface of the station liaison officer. S5. Confirmation of track entry completion: When avoiding a vehicle, after the vehicle has passed, the work team contacts the station liaison to confirm that it is safe to continue work on the track. The safety officer then presses another control button to report the "track entry completed" information. The work team's status will be updated to "working" in real time on the station liaison's tablet interface.

[0014] The beneficial effects of this invention are as follows: 1. This invention, by setting up bone conduction headphones and a laser generator, enables voice broadcast content to be transmitted through bone conduction headphones, which can reduce the impact of noise in the operation site without affecting the personnel's ability to hear the sound. The control signal of the flashing warning light is transmitted to the laser generator, causing the light spot to flash continuously in front of the personnel's eyes, so that the personnel can avoid failing to notice the flashing warning light signal on the display screen in time. At the same time, the protective handheld terminal is worn on the wrist, and its panel always follows the hand and can be quickly turned towards the personnel, which greatly facilitates the operation of the personnel. 2. By setting up an enhanced antenna, the signal repeater attached to the self-adhesive arm ring can be connected to the protective handheld terminal via an antenna connection cable. This allows the enhanced antenna to remain in an upward position with the arm in most cases, thereby enhancing the wireless signal and ensuring the stability of wireless signal transmission at the operation site. Similarly, in areas with high signal strength, the signal repeater can be omitted, and the enhanced antenna can be left inside the storage cylinder. 3. This invention, by setting up a storage screw and a transparent protective cover, allows the storage screw and the transparent protective cover to respectively store and protect the enhanced antenna and the handheld terminal under normal conditions. In actual operation, the transparent protective cover covers the panel of the handheld terminal, effectively preventing accidental contact. When operation is required, the operator can screw the storage screw to flip the transparent protective cover upwards to expose the handheld terminal for operation. The storage hook inside the transparent protective cover can separately store the external device connection cable to prevent loss. Attached Figure Description

When it is necessary to exit the track to avoid the vehicle or to stop the work by pulling the rope in place, the display screen 101 will trigger the light to flash. The flashing will stop after the safety officer performs the "avoiding the vehicle completed" action to remind the person in charge of the work to organize the avoidance of the vehicle. If the person in charge of the work needs to temporarily issue a warning effect with the warning light, he can manually press the control button 103 to turn on the warning light function of the display screen 101 and trigger the flashing. Pressing another control button 103 will stop it. The function key 105 on the protective handheld terminal 1 held by the safety officer has functions such as "up" and "down", while the function key 105 on the protective handheld terminal 1 held by the operator is a reserved function key.

[0022] More specifically, when wearing the safety protection terminal equipment used at railway work sites, first screw on the storage screw 17 to rotate the transparent protective cover 18 around the hanging rod 19, then remove the transparent protective cover 18. Next, pull out the reinforcing antenna 12 that was originally inserted into the antenna hole 108, remove the antenna connecting wire 13 from the storage hook 20 inside the transparent protective cover 18, pass one end of the antenna connecting wire 13 through the through hole on the storage screw 17 and insert it into the antenna hole 108 on the protective handheld terminal 1, and pass the other end through the snagging strap 9 on the self-adhesive arm ring 8 and insert it into the antenna hole on the signal repeater 11. In step 108, the storage cylinder 17 and the transparent protective cover 18 are reinstalled on the protective handheld terminal 1. Then, the enhanced antenna 12 is plugged into the signal repeater 11. After that, one end of the external device connection cable 2 on the bone conduction earphone 5 is passed through the strap 9 and plugged into the external hole 107. The fastening thread caps 14 on the external device connection cable 2 and the antenna connection cable 13 are screwed into the first fastening screw rings 15 for fastening. Then, the self-adhesive arm ring 8 is put on the arm in sequence, and the self-adhesive wristband 7 and the protective handheld terminal 1 are put on the wrist. Finally, the glasses frame 3 is put on to complete the wearing of the terminal device. During operation: Power on: Rotate the power knob 104 clockwise to turn on the power and adjust to a suitable volume. At this time, the system will perform a self-test until the speaker hole 102 plays a voice message indicating successful power-on. Voice alarm and confirmation: In normal working condition, if an alarm is triggered, the protective handheld terminal 1 will automatically play the alarm through the speaker hole 102 in a loop. After receiving the alarm information, the protection personnel will press the corresponding function key 105 according to the route to confirm the up or down. If the confirmation button is pressed incorrectly or the function key 105 is not pressed in time within 3 times of the content playback frame, the alarm information will continue to be played repeatedly until the button is pressed correctly, or if a more urgent alarm is triggered, the alarm information will be played continuously. Confirmation of Train Avoidance Completion: Depending on the train operation, if it is necessary to go off track to avoid a train or to stop the operation by pulling the rope in place, after the train avoidance is organized, the safety officer presses control button 103 to report the information of "Train Avoidance Completed". The status of the work group will be updated to "Train Avoidance in Progress" in real time on the tablet interface of the station liaison officer. Confirmation of completion of track entry: When avoiding a vehicle, after the vehicle has passed, the work team will contact the station liaison to confirm that it is safe to continue working on the track. The safety officer will then press another control button 103 to report the information that "track entry is complete". The work team's status will be updated to "working" in real time on the station liaison's tablet interface. By setting up bone conduction headphones 5 and laser generator 6, when voice broadcasts are made through speaker holes 102, the broadcast content is transmitted to the bone conduction headphones 5 via external device connection cable 2, and then transmitted to the ears of the safety officer and operator through bone conduction. The bone conduction headphones 5 can transmit voice information in a timely manner through wired connection, reducing the impact of noise at the operation site, and will not block the personnel's ears, affecting their ability to hear the sound at the scene. When the display screen 101 starts flashing warning lights, the control signal is also transmitted to the laser generator 6 on the lens frame 3 via external device connection cable 2, and light is emitted onto the two dustproof lenses 4 through two output terminals, causing the light spots to flash continuously in front of the personnel's eyes, so that the personnel can see the flashing warning light signal on the display screen 101 in time. At the same time, the protective handheld terminal 1 is worn on the wrist, and its panel always follows the hand and can be quickly turned towards the personnel, which greatly facilitates the operation of the personnel.

[0023] like Figure 1 , Figure 8 As shown, specifically, a clip 10 is attached to the self-adhesive arm ring 8, a signal repeater 11 is fixedly installed on one side of the clip 10, an enhanced antenna 12 is inserted into the top of the signal repeater 11, and antenna holes 108 are opened on one side of both the protective handheld terminal 1 and the signal repeater 11. An antenna connecting wire 13 is inserted into the inside of the antenna hole 108 on the signal repeater 11, and one end of the antenna connecting wire 13 passes through the gathering strap 9 and is inserted into the inside of another antenna hole 108.

[0024] More specifically, by setting up the enhancement antenna 12, the signal repeater 11, which is attached to the self-adhesive arm ring 8, can be connected to the protective handheld terminal 1 via the antenna connection cable 13. This allows the enhancement antenna 12 to remain in an upward position with the arm in most cases, thereby enhancing the wireless signal and ensuring the stability of wireless signal transmission at the operation site. Similarly, in areas with high signal strength, the signal repeater 11 can be omitted, and the enhancement antenna 12 can be left inside the storage cylinder 17.

[0025] like Figure 3 , Figure 8 As shown, specifically, the bottom end of the external device connection cable 2 and both ends of the antenna connection cable 13 are movably fitted with fastening thread caps 14. The protective handheld terminal 1 has first fastening screw rings 15 fixedly installed on both sides and one side of the signal repeater 11. The positions of the three first fastening screw rings 15 correspond to the positions of the external hole 107 and the two antenna holes 108, respectively. The three fastening thread caps 14 are screwed onto the three first fastening screw rings 15.

[0026] In this embodiment, the fastening threaded cap 14 has a sliding hole, and the fastening threaded cap 14 is sleeved on the external device connection line 2 or the antenna connection line 13 through the sliding hole. The inner diameter of the sliding hole is smaller than the outer diameter of the terminals of the external device connection line 2 and the antenna connection line 13.

[0027] More specifically, by setting fastening thread caps 14, the fastening thread caps 14 respectively fitted on the external device connection line 2 and the antenna connection line 13 can be screwed onto each of the first fastening thread rings 15, locking the connection ends of the external device connection line 2 and the antenna connection line 13, preventing the connection terminals of the external device connection line 2 or the antenna connection line 13 from loosening when the operator pulls on the external device connection line 2 or the antenna connection line 13 during on-site operation, thus affecting the control of the bone conduction headphones 5 and the laser generator 6 and the signal transmission of the enhancement antenna 12.

[0028] like Figure 1 , Figure 8 As shown, specifically, a self-adhesive arm ring 8 is provided between the protective handheld terminal 1 and the mirror frame 3, and a drawstring 9 is fixedly installed on one side of the self-adhesive arm ring 8. The external device connection line 2 is located inside the drawstring 9.

[0029] More specifically, by setting up the gathering band 9, both the external device connection cable 2 and the antenna connection cable 13 are gathered inside the gathering band 9, so that both the external device connection cable 2 and the antenna connection cable 13 are restricted to one side of the operator's arm, preventing the external device connection cable 2 and the antenna connection cable 13 from being messy and scattered, thus preventing them from hindering the operator's operation.

[0030] like Figure 2 , Figure 5 , Figure 9 As shown, specifically, a second fastening screw ring 16 is fixedly installed on one side of the protective handheld terminal 1, and a first fastening screw ring 15 is located inside the second fastening screw ring 16. A storage screw cylinder 17 is screwed onto the second fastening screw ring 16. One end of the storage screw cylinder 17 has a through hole, and the antenna connection line 13 is located inside the through hole. A transparent protective cover 18 is fixedly sleeved on one end of the storage screw cylinder 17. The transparent protective cover 18 is located on the top of the protective handheld terminal 1. A hanging groove 1801 is opened on the other side of the transparent protective cover 18. A hanging rod 19 is fixedly installed on the side of the protective handheld terminal 1 away from the storage screw cylinder 17. The hanging rod 19 is located inside the hanging groove 1801. Multiple storage hooks 20 are fixedly installed on the inner wall of the transparent protective cover 18.

[0031] More specifically, by setting up a storage screw 17 and a transparent protective cover 18, the storage screw 17 and the transparent protective cover 18 can respectively store and protect the enhanced antenna 12 and the protective handheld terminal 1 under normal conditions. In actual operation, the transparent protective cover 18 covers the panel of the protective handheld terminal 1, effectively preventing accidental touch by personnel. When operation is required, the personnel can turn the storage screw 17 to drive the transparent protective cover 18 to flip upward to expose the protective handheld terminal 1 for operation. The storage hook 20 inside the transparent protective cover 18 can separately store the external device connection cable 2 to prevent loss.

[0032] A safety protection method for railway work sites includes the following steps: S1. Wearing: Twist the storage screw 17 to remove the transparent protective cover 18, then pull out the reinforcing antenna 12, remove the antenna connection cable 13, and pass one end of the antenna connection cable 13 through the through hole and plug it into the protective handheld terminal 1.
