Problems solved by technology

In the Internet of Things monitoring system, when the signal is collected at a high frequency (such as above 400Hz), the battery power of the acquisition terminal will be exhausted soon. Due to the rapid power consumption and frequent replacement of a large number of acquisition terminal batteries, the workload will be huge and the time consumption will be huge.
Therefore, the above traditional systems are difficult to solve the problem of reducing sensor wiring and maintaining a long-term and convenient power supply for the wireless monitoring system
[0008] Finally, the traditional monitoring system does not have modular batteries, so it is difficult to choose different numbers of batteries for flexible power supply according to the length of monitoring time and the size of the monitoring space.
Moreover, traditional custom batteries take up a lot of space, and it takes a lot of time to install, replace and maintain

Embodiment 1

[0085] Example 1: Inside the high-speed rail equipment warehouse, when long-term structural health monitoring needs to monitor vibration signals, the acquisition function module 2 equipped with a vibration sensor inside is spliced ​​to the main module 1 to collect vibration signals. When splicing, it is necessary to connect the module magnetic socket 29 at the bottom of the acquisition function module 2 with the Port1 magnetic socket 17 of the main module upper cover 11, and carry out I2C protocol communication to collect vibration signals. The auxiliary fixing holes 25 of the module are used for auxiliary fixing to prevent the vibration from falling off. At this time, the collection node has the function of monitoring the vibration signal.

[0086] When vibration signals are collected at high frequency and on a large scale, the transmission speed of the communication module is required to be high. At this time, the communication module 3 with the WIFI module inside can be spl...

Embodiment 2

[0088] Embodiment 2: In the body of a railway freight car, when long-term structural health monitoring needs to monitor temperature and humidity signals, vibration signals and strain signals, the acquisition function module 2 equipped with a temperature and humidity sensor inside is spliced ​​to the main module 1 to perform temperature and humidity signal monitoring. collection. When splicing, it is necessary to connect the module magnetic male seat 29 at the bottom of the acquisition function module 2 with the Port2 magnetic female seat 18 on the upper cover 11 of the main module to communicate. The auxiliary fixing holes 25 are used for auxiliary fixing to prevent vibration falling off. At this time, the collection node has the function of monitoring temperature and humidity signals. The vibration module is built similar to example 1. The temperature and humidity collection unit and the vibration collection unit are connected using the tree structure proposed by the presen...

Abstract

The invention provides a modularized magnetic type wireless monitoring system and method. The system comprises a server unit and at least one acquisition unit, the server unit is in communication connection with each acquisition unit, and the acquisition unit is a single acquisition node or an acquisition node group; wherein the single acquisition node or the acquisition node group comprises a magnetic type acquisition module, the magnetic type acquisition module comprises a main module, an acquisition function module and a communication module, and the main module controls the acquisition function module to acquire a monitoring signal according to a received acquisition task and uploads the monitoring signal through the communication module. The acquisition unit is small in size and easy to deploy, and the modular structure is easy to upgrade, replace and expand. The system networking is flexible, long-term power supply of the acquisition unit is ensured, parallel wiring is reduced, and corresponding functional modules can be flexibly replaced according to different functional requirements so as to monitor different types of signals.

Description

technical field [0001] The present invention relates to the field of wireless acquisition signal monitoring, in particular to a modular magnetic suction wireless monitoring system and method. Background technique [0002] In recent years, with the continuous progress of embedded computing technology, sensing technology, wireless communication technology and technology, the rapid development of digital sensors and systems has been promoted, enabling them to collect and monitor a variety of physical signals. An important part of health monitoring applications, IoT applications, and environmental assessment applications. [0003] At present, in the traditional wireless monitoring system, the analog signal monitoring system converts the collected analog signals of various physical quantities into electrical signals for monitoring, and the Internet of Things type signal monitoring system mostly uses wireless node networking for monitoring. However, the above traditional wireless...
