Description

Technical Field

[0001] The present invention relates to the field of railway vehicle anti-slipping, and in particular to a railway intelligent anti-slipping fastener. Background Art

[0002] Anti-slip fasteners are a crucial tool for preventing vehicles parked on the track from slipping. They work by hooking the fastener's hook to the vehicle's brake chain. Turning the fastener's nut by cranking the handle tightens the chain, creating friction between the brake shoe and the wheel tread to generate braking force. Currently, fastener placement is performed manually, which can lead to human error and incorrect track placement. This puts vehicles at risk of slipping if not promptly secured, potentially causing derailment, switch jams, or even a vehicle sliding onto the main line and colliding with a passenger train, resulting in a major safety incident. Currently, all intelligent fasteners lack positioning capabilities, making it impossible to detect incorrect track placement and track lost fasteners. Furthermore, beyond the coverage of the railway's proprietary wireless local area network, communication between the intelligent fastener and the monitoring center is lost, making it even more difficult to locate lost fasteners.

[0050] Technical principle of the present invention:

[0051] 1. Before using the railway anti-slip fastener, after the operator takes the railway anti-slip fastener out of the fastener storage device, the Bluetooth module cannot receive the positioning information of the Bluetooth beacon in the warehouse, and the microprocessor determines that the railway anti-slip fastener is out of the warehouse. The microprocessor uses the first wireless communication module to send the information that the railway anti-slip fastener has left the warehouse to the monitoring center of the railway internal network through the railway internal wireless LAN, and starts to use the first wireless communication module to send the heartbeat information outside the warehouse to the monitoring center of the railway internal network through the railway internal wireless LAN at a set period for remote diagnosis of whether the railway anti-slip fastener is normal.

[0052] 2. When an operator carries the railway intelligent anti-slip fastener taken out from the fastener storage device to the track of the vehicle where the railway intelligent anti-slip fastener is to be installed, if the microprocessor fails to receive positioning information sent by the Bluetooth positioning module for a period of time, the positioning module is activated, and the microprocessor obtains the latitude and longitude information of the positioning module. The microprocessor uses the first wireless communication module to send the latitude and longitude information of the railway anti-slip fastener to the monitoring center of the railway internal network through the railway internal wireless local area network at a set period.

[0053] 3. After the operator approaches the track carrying the railway intelligent anti-slip fastener, the microprocessor receives the positioning information broadcast by the track Bluetooth beacon through the Bluetooth module, then turns off the positioning module. When it is determined that the track number and the relative position of the track have changed, the first wireless communication module is used to send the positioning information to the monitoring center of the railway internal network through the railway internal wireless LAN.

[0054] When installing the intelligent anti-skid fastener, the operator hooks the device onto the brake chain of the vehicle's manual brake, secures the clamp to the vehicle body, and then uses a crank to rotate the screw to tighten the chain. During the tightening process, the tension acquisition module measures the tension applied to the tension sensor and transmits it to the microprocessor. The microprocessor, through the tension acquisition module, determines that the tension value has changed by more than a set value (1 kN). It then controls the voice module to broadcast the tension value through the speaker and transmits the tension value information to the monitoring center of the railway's internal network via the first wireless communication module via the railway's internal wireless LAN. When the microprocessor, through the tension acquisition module, determines that the tension value has changed by more than 10 kN, it controls the voice module to announce the completion of the installation through the speaker, controls the indicator light to flash green for 10 seconds, and transmits the completion information to the monitoring center of the railway's internal network via the first wireless communication module via the railway's internal wireless LAN. The monitoring center, based on the location information of the track Bluetooth beacon with the strongest signal field, determines whether the track is correctly installed. If the track is incorrectly installed, it issues an "incorrect track" alarm, alerting remote monitoring personnel.

[0055] During the anti-skid process, if the microprocessor detects that the tension value is within the range of [1 kN, 10 kN] for more than 30 seconds, the control module will announce insufficient tension through the speaker, control the indicator light to flash red rapidly, and send an insufficient tension alarm message to the monitoring center on the railway's internal network. If the microprocessor determines that the tension value or the track number and relative position of the tracks have changed, the first wireless communication module will transmit the tension value, track number, and relative position of the tracks to the monitoring center on the railway's internal network via the railway's internal wireless local area network.

[0056] 6. During the anti-skid process, when the microprocessor determines through the tension acquisition module that the tension value is greater than 14.7KN or less than 10KN, the control voice module broadcasts the alarm of excessive tension or insufficient tension through the loudspeaker, and the control indicator light flashes red quickly, thereby prompting the on-site workers to make adjustments; and the first wireless communication module is used to send the alarm message of excessive tension or insufficient tension through the railway's internal wireless LAN to the monitoring center of the railway's internal network, prompting the remote monitoring management personnel.

[0057] During the anti-skid process, when the microprocessor uses the Bluetooth module to determine that the railway intelligent anti-skid fastener in the normal anti-skid state has a displacement greater than the set value (5 meters), the first wireless communication module is used to send a circuit breaker alarm message through the railway's internal wireless LAN to the monitoring center of the railway's internal network so that timely remedial measures can be taken.

[0058] 7. When removing the intelligent anti-slip fastener, the operator loosens the fastener with a crank. The microprocessor, through the tension acquisition module, determines that the change in tension exceeds a set value (1 kN). It then controls the voice module to broadcast the tension value through the speaker and, using the first wireless communication module, transmits the tension value, track number, and relative track position via the railway's internal wireless LAN to the monitoring center within the railway network. When the microprocessor determines that the tension value detected by the tension acquisition module reaches the set removal value (0.5 kN), it controls the voice module to announce the completion of the removal through the speaker and, using the first wireless communication module, transmits the message of completion via the railway's internal wireless LAN to the monitoring center within the railway network.

[0059] 8. After the railway intelligent anti-slip fastener is removed, if the Bluetooth module can receive the positioning signal of the track Bluetooth beacon, the microprocessor uses the first wireless communication module to send the location information of the fastener to the monitoring center of the railway internal network through the railway internal wireless LAN; if the Bluetooth module cannot receive the positioning signal of the track Bluetooth beacon, the microprocessor uses the first wireless communication module to send the latitude and longitude information of the railway intelligent anti-slip fastener detected by the positioning module to the monitoring center of the railway internal network through the railway internal wireless LAN.

[0060] 9. After the railway intelligent anti-slip fastener is placed back into the fastener storage device, the microprocessor receives the positioning information sent by the Bluetooth beacon in the warehouse through the Bluetooth module, and then uses the first wireless communication module to send information that the railway anti-slip fastener is in the warehouse to the monitoring center of the railway internal network through the railway internal wireless LAN. It also starts to use the first wireless communication module to send the heartbeat information in the warehouse to the monitoring center of the railway internal network through the railway internal wireless LAN at a set period for remote diagnosis of whether the railway intelligent anti-slip fastener is normal.

[0061] 10. When the intelligent anti-slip fastener is outside the coverage of the station's internal wireless LAN, the microprocessor determines, via the first wireless communication module, that the first wireless communication network signal has been lost. It then activates the second wireless communication module to periodically transmit intelligent anti-slip fastener tracking information to a monitoring center via the internet wireless communication network. To ensure information security, this tracking information only includes the intelligent anti-slip fastener's unique number and latitude and longitude information.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
