Description

Technical Field

[0001] This utility model relates to the field of switch machine condition monitoring technology, specifically to a real-time monitoring system for immersion in water in a buried switch machine. Background Technology

[0002] Switch machines are key equipment in railway signaling systems. Through precise control and operation, switch machines enable accurate switching and locking of turnouts, thereby ensuring that trains can safely and smoothly change their direction of travel.

[0003] Switch machines are typically installed outdoors and are greatly affected by rain. If water enters the switch machine, it can affect train operation. Current technology usually detects water ingress in switch machines by using an exhaust fan to draw air from inside the machine and transmitting the data to a humidity detector. The humidity detector then measures the humidity to determine if there is a leak. However, relying solely on a humidity detector to measure the humidity of the air inside the switch machine to determine if there is a leak is highly susceptible to environmental influences, leading to significant errors.

[0011] In some embodiments, the leakage sensing cable is fixed to the bottom of the switch machine with adhesive tape, and the water immersion transmitter is connected to the leakage sensing cable to monitor whether water has entered the switch machine by detecting changes in capacitance.

[0012] In some embodiments, the power module is used to provide power to the acquisition module and the transmission module. The power module includes a 24V power submodule for converting the input voltage into a stable 24V DC output.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] Please see Figures 1-2 This utility model provides a real-time monitoring system for water immersion of an underground switch machine, comprising: a data acquisition module 1, a transmission module 2 connected to the data acquisition module 1, an alarm module 3 connected to the transmission module 2, a monitoring module 4 and a mobile terminal 5 connected to the alarm module 3, and a power supply module 6 connected to the data acquisition module 1 and the transmission module 2 respectively.

[0029] In some embodiments, the acquisition module 1 is used to acquire water immersion information of the switch machine, and includes: a temperature and humidity transmitter 11, a water immersion transmitter 12, and a leakage sensing cable 13 connected to the water immersion transmitter 12. The temperature and humidity transmitter 11 is installed on the side of the switch machine and is used to acquire the temperature and humidity inside the switch machine. In some embodiments, the temperature and humidity transmitter 11 can acquire and transmit temperature and humidity data through an RS485 interface and Modbus protocol. The water immersion transmitter 12 is adapted to the leakage sensing cable 13 and is used to acquire whether water has entered the switch machine.

[0030] Specifically, the leakage sensing cable 13 is located at the bottom of the switch machine. In some embodiments, the leakage sensing cable 13 can be fixed to the bottom of the switch machine with adhesive tape. When liquid approaches or comes into contact with the leakage sensing cable 13, the capacitance value of the leakage sensing cable 13 increases. The change in capacitance is detected by the water immersion transmitter 12 connected to the leakage sensing cable 13, and a corresponding signal is output to the monitoring module 3, so as to monitor whether water enters or leaks inside the switch machine.

[0031] In some embodiments, the transmission module 2 is connected to the acquisition module 1 and is used to transmit the water immersion information of the switch machine acquired by the acquisition module 1 to the monitoring module 3. In some embodiments, the transmission module 2 may include a 4G serial port server 21, which can transmit the data of the serial port device (temperature and humidity transmitter 11 or water immersion transmitter 12) to the Internet of Things terminal on the Internet through the 4G LTE cellular network, thereby realizing remote monitoring, data acquisition and device networking.

[0032] In some embodiments, the alarm module 3 is used to issue an alarm message when the switch machine is submerged in water. Further, the alarm module 3 includes a server 31 and an alarm submodule 32 connected to the server 31. The server 31 is used to determine whether the switch machine is submerged in water. For example, the server 31 has a built-in submersion information threshold. The server 31 can compare the submersion information collected by the acquisition module 1 with the preset submersion information threshold. When the temperature value and humidity value collected by the acquisition module 1 are greater than the preset temperature threshold and humidity threshold, or when the water immersion transmitter 12 reports that the leakage sensing cable 13 is submerged in water, the server 31 can determine that the switch machine is submerged in water. The alarm submodule 32 is used to issue an alarm message when the server 31 determines that the switch machine is submerged in water. In some embodiments, the alarm message can be an audible and visual alarm message, or the alarm submodule 32 can send an alarm message such as a text message or voice call to the mobile terminal 5.

[0033] In some embodiments, the monitoring module 4 is used to acquire and display the water immersion information of the switch machine. Further, the monitoring module 4 includes a monitoring terminal 41, which can be an industrial control computer used to display the water immersion information. The water immersion information can be real-time water immersion information, or it can include real-time water immersion information and historical water immersion information. For example, the monitoring terminal 41 can display the water immersion information of the acquisition module 1 in the form of a line graph, so that the operator can view the water immersion information of the switch machine in real time.

[0034] In some embodiments, the mobile terminal 5 is used to receive alarm information and view water immersion information. For example, the mobile terminal 5 can receive alarm SMS messages sent by the alarm module 3 via a mobile phone, or view water immersion information transmitted by the temperature and humidity transmitter 11 via a mobile app, or view water immersion information on the monitoring terminal 31.

[0035] In some embodiments, the power module 6 is used to provide power to the acquisition module 1 and the transmission module 2. In some embodiments, the power module 6 includes a 24V power submodule 61, which is used to convert the input voltage (such as AC 220V or DC 12V / 48V) into a stable 24V DC output.

[0036] Furthermore, the power module 6 also includes a circuit breaker 62 connected to the 24V power submodule 61, which is used to automatically cut off the current when the circuit experiences overload, short circuit or ground fault, thereby preventing equipment damage or fire risk.

[0037] Finally, it should be noted that the embodiments disclosed in this utility model are merely preferred embodiments of this utility model and are only used to illustrate the technical solutions of this utility model, not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
