Description

Technical Field

[0001] The present application relates to the technical field of track signal system monitoring, and in particular to a relay status monitor and a status monitoring system. Background Art

[0002] Railway signal relays are specialized electromagnetic switching devices used in various railway signaling equipment or systems. They consist of an electromagnetic coil, a contact assembly, a transmission system, and components that ensure the contacts close or open. Major types include DC stepless relays, polarity-biased relays, and polarity-maintaining relays. Railway signal relays use the magnetic force generated by current in the electromagnet coil to actuate the armature and movable parts, thereby changing the operating state of the contact system. To ensure the reliable operation of railway signal systems, the status of railway signal relays must be monitored.

[0003] Currently, non-contact Hall-effect current sensors are commonly used to monitor the status of railway signal relays. During installation, the excitation circuit cable must be soldered to the relay base, and the Hall-effect current sensor's magnetic ring must be attached to the relay's excitation circuit. This complex installation process allows the Hall-effect current sensor to monitor whether the railway signal relay is energized. Furthermore, since the excitation current of railway signal relays is typically only a few milliamperes, a highly sensitive Hall-effect current sensor is required. However, these Hall-effect current sensors are bulky and costly. Utility Model Content

[0022] In order to make the purpose, technical solutions and advantages of this application clearer, the following embodiments are given to further illustrate this application in detail.

[0023] Railway signal relays are specialized electromagnetic switching devices used in various railway signaling equipment or systems. They consist of an electromagnetic coil, a contact assembly, a transmission system, and components that ensure the contacts close or open. Major types include DC stepless relays, polarity-biased relays, and polarity-maintaining relays. Railway signal relays use the magnetic force generated by current in the electromagnet coil to actuate the armature and movable parts, thereby changing the operating state of the contact system. To ensure the reliable operation of railway signal systems, the status of railway signal relays must be monitored.

[0024] like Figure 1 The schematic diagram of an embodiment of a relay condition monitoring system is shown. The relay condition monitoring system includes at least one condition monitor 1 and a monitoring host 2. The condition monitor 1 is used to detect the operating status of different relays. Furthermore, the monitoring host 2 is communicatively connected to the condition monitor 1 to record and display the operating status of the monitored relays. For example, in a specific implementation scenario, multiple condition monitors 1 can be simultaneously communicatively connected to a monitoring host 2. This allows for simultaneous condition monitoring of multiple relays.

[0025] The status monitor 1 includes a housing for attaching to the exterior of a relay, and a magnetic induction switch 11, a data processing module 12, and a battery module 13 disposed inside the housing. For example, the magnetic induction switch 11 may include a Hall switch or a magnetron. The magnetic induction switch 11 is disposed on the inner bottom surface of the housing and is configured to turn on when detecting the magnetic field of the relay. The data processing module 12 outputs a digital signal indicating that the relay is closed during operation. The battery module 13 is configured to supply power to the data processing module 12. The magnetic induction switch 11, the data processing module 12, and the battery module 13 are connected in series in the same circuit.

[0026] In the relay state monitor 1 and state monitoring system, when the relay coil is energized, the armature is attracted, and the relay's node group closes and conducts. The magnetic field generated by the relay coil triggers the magnetic induction switch 11 of the state monitor 1 to conduct. The data processing module 12 then sends a digital signal indicating the relay is conducting to the monitoring host 2. The monitoring host 2 then receives and displays the operating status of each relay being monitored in the track signaling system. The state monitor 1 is compact and easy to install, offering high sensitivity, reliability, and low cost.

[0027] In a preferred embodiment, the condition monitor 1 is preferably placed on the exterior of the relay, facing the coil of the relay to be monitored, and located on the side of the relay surface closest to the coil. In this case, the condition monitor 1 is located at the position where the relay's magnetic field is strongest, thereby improving the monitoring sensitivity.

[0028] In a preferred embodiment, the status monitor 1 further includes a wireless transmission module 14, which is configured at the signal output end of the data processing module 12. For example, the wireless transmission module 14 may include a Zigbee communication module or a Bluetooth communication module.

[0029] Accordingly, the condition monitoring system may further include a wireless receiver 3, which is used to receive the digital signal sent by the wireless transmission module 14 of the condition monitor 1 and transmit it to the monitoring host 2. For example, when the wireless transmission module 14 may include a Zigbee communication module, the wireless receiver 3 may be a Zigbee signal receiving device.

[0030] In this way, the monitoring host 2 can monitor the relays in the track signal system in real time by wireless transmission, thus reducing the number of cable connections and making the monitoring system more convenient to install.

[0031] In another embodiment, the data processing module 12 may also be configured with a signal output interface to transmit digital signals to the outside in a wired manner.

[0032] Preferably, the data processing module 12 is configured to operate in a sleep-wake-sleep mode after the magnetic induction switch 11 is turned on. In this way, operating in a low-power mode can reduce power consumption and reduce the frequency of replacing the battery module 13.

[0033] The present application relates to the technical field of track signal system monitoring, and in particular to a relay status monitor 1 and a status monitoring system. The status monitor 1 includes a shell for attaching to the surface of a relay, and a magnetic induction switch 11, a data processing module 12, and a battery module 13 arranged inside the shell. When the armature is attracted after the coil of the relay is energized, the magnetic field generated by the coil of the relay triggers the magnetic induction switch 11 of the status monitor 1 to turn on. At this time, the data processing module 12 will send a digital signal indicating that the status of the relay is on to the monitoring host 2, and the monitoring host 2 will be able to receive and display the working status of each relay being monitored in the track signal system. Among them, the status monitor 1 is small in size and easy to install, and has the advantages of high sensitivity, high reliability, and low cost.

[0034] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
