[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, the directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the creation of this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] Example 1: A modular sensor, such as Figure 1 As shown, it includes a power module 1 and a data acquisition module 6, with a multi-mode connector provided between the power module 1 and the data acquisition module 6, such as... Figure 6 As shown, the multimode connector includes connector I13, which is connected to several connecting lines 15, and the several connecting lines 15 are connected to connector II11; connector I13 is connected to power module 1, and connector II11 is connected to data acquisition module 6.

[0027] This invention enables the rapid combination of sensors with different functions according to equipment requirements, and allows sensors to be started and stopped at any time. It avoids the problems of sensor waste and high maintenance costs caused by sensor battery replacement due to expiration, temporary addition of monitoring items, intermittent start and stop of sensors, and temporary testing of idle sensors.

[0028] Example 2: A modular sensor, such as Figure 7 and Figure 8 As shown, connector I13 includes housing I, on which a plug I14 is provided; connector II11 includes housing II, on which a plug interface II12 is provided; as Figures 2-5 As shown, power module 1 includes a sealed housing I, with a connector I3 inside; data acquisition module 6 includes a sealed housing II, with a plug II7 on the sealed housing II; plug I14 is inserted into connector I3; connector II12 is inserted into plug II7. Both connector I3 and connector II12 have communication terminals 4 and connecting magnetic posts 5. Both plug I14 and plug II7 have communication ports 8 and connecting magnetic rings 9. Sealing housings I and II are made of polyurethane, making them wear-resistant and corrosion-resistant enough to adapt to the working environment of equipment monitoring in different process sections of a coal preparation plant.

[0029] The power module 1 and the data acquisition module 6 can be directly connected via the connector I3 and the plug II7.

[0030] Both plug I (14) and plug II (7) are equipped with sealing rings 10. Both sealing shell I and sealing shell II are equipped with magnetic bases 2.

[0033] The multimode connector can support the combination of 4 acquisition modules to achieve simultaneous monitoring by multi-functional sensors. The line length can support a communication distance of 600mm, which can realize distributed synchronous monitoring or stepped monitoring of the monitoring area of ​​the equipment, making it easier to find abnormal locations more accurately.

[0034] In use, select the appropriate power module 1 and data acquisition module 6 according to the site requirements; apply silicone grease to the mating surfaces of the power module 1 and the corresponding data acquisition module 6, and then assemble them together. If a multi-functional sensor is required, a multi-mode communicator and the corresponding data acquisition module 6 are needed; clean the area where the sensor will be installed, removing any oil or dirt; align the magnetic mounting surface of the sensor magnetic base 2 with the installation position, and perform magnetic installation, or apply adhesive to the magnetic mounting surface of the sensor to assist in magnetic installation. When replacing the power module 1 or data acquisition module 6, first remove the entire sensor or the corresponding module, replace the power module 1 or data acquisition module 6 that needs to be replaced, and then install the sensor in its original position.
