Description

Technical Field

[0001] This utility model belongs to the field of electrical control technology, and specifically relates to a mobile relay operation monitoring device. Background Technology

[0002] With the in-depth development of automatic control technology, various relays are widely used in production processes, making their stable and reliable operation particularly important. On the one hand, relay manufacturers are innovating production technologies and optimizing relay structures; on the other hand, they are striving to improve production processes and enhance reliability. In practical work, relays with a low probability of malfunctioning in the control circuit often cannot be identified. The common approach is to replace all relays in the control circuit or use a substitution method to check each relay individually, lacking a monitoring and identification device for individual faulty relays.

[0003] To address the above issues, the existing solutions are: Solution 1: Design a lighting control circuit using relay contacts, illuminating the light when the relay activates. Solution 2: Configure a dedicated camera to monitor the operation of the faulty relay. Solution 3: Use a millisecond-level digital input scanning module to record the abnormal repositioning process of the relay.

[0004] The shortcomings of existing technologies are as follows: Option 1 is for critical relays. Option 2 is complex to install and has high manufacturing costs. Option 3 has high performance requirements for monitoring equipment and high device costs.

[0005] Therefore, it is necessary to design a system that can monitor the status of all relays while also meeting the requirement of low cost. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a mobile relay operation monitoring device to monitor the position of suspicious relays in the control circuit, so as to identify and locate the faulty relay, find out the problem, and solve the efficiency and cost problems caused by replacing all relays in the entire control circuit due to the instability of a single relay.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A mobile relay operation monitoring device includes a housing, within which a network time synchronization module and a displacement monitoring module are housed. A magnetic adsorption module is mounted on the housing for adsorption onto a metal component. The displacement monitoring module is connected in series with the normally open or normally closed contact of the relay via test leads.

[0009] Preferably, the network time synchronization module, the position monitoring module, and the display screen are connected via a communication serial port.

[0010] Preferably, the network time synchronization module is a SYN2931 NTP receiver module.

[0011] Preferably, the housing is provided with straps, which are matched with the magnetic adsorption module to fix the housing to a cylindrical or strip-shaped metal component.

[0012] The present invention can achieve the following beneficial effects:

[0013] This device can conveniently and efficiently determine whether relays in a control circuit are operating correctly, saving manpower for monitoring and avoiding the need to replace all relays in the control circuit, thus improving work efficiency and saving maintenance costs. Real-time monitoring of relays is achieved through on-site installation, utilizing spare contacts to easily determine whether a relay is operating normally without disconnecting wires. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0017] In the diagram: Magnetic adsorption module 1, strap 2, outer shell 3. Detailed Implementation

[0018] Preferred solutions include Figure 1-2 As shown, a mobile relay operation monitoring device comprises a magnetic adsorption module, a network time synchronization module, a position monitoring module, and test leads. The device is placed near a suspected relay using the magnetic adsorption module. The timing module of the mobile device is adjusted via the network, and the test leads are connected to the normally open (normally closed) contacts of the suspected relay. The position monitoring module is adjusted to record inputs (and vice versa). When the control circuit activates, the timing of the relay's operation is checked to ensure it follows the control logic, thus determining if the relay is functioning correctly and if replacement is necessary.

[0019] The network time synchronization module is a SYN2931 NTP receiver module from Xi'an Synchronous Electronics Technology Co., Ltd. In addition to the existing SYN2931 NTP receiver module, it adds time synchronization functionality for satellite positioning systems such as GPS / BeiDou to improve the accuracy and reliability of time synchronization. This ensures high-precision time synchronization even under unstable network conditions. The position monitoring module is a ZY-K402 from Zhiyuan Electronics. The power supply for the entire device is an NDR-75-24 from Mingwei (Taiwan).

[0020] In addition, adding a Wi-Fi or 4G / 5G module supports remote access and monitoring, allowing users to view the device status in real time via a mobile app or web interface.

[0021] Furthermore, the housing is equipped with straps that mate with the magnetic adsorption module to secure the housing to cylindrical or strip-shaped metal components. Specifically designed for cylindrical structures, where the magnetic force alone is insufficient to secure the entire device, the strap structure allows it to be attached to cylindrical structures or other similar components.

[0022] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
