Multi-sensor compatible equipment management device and system based on Internet of Things

Abstract

The invention relates to a multi-sensor compatible equipment management device and system based on the Internet of Things. The system includes an RTU concentrator provided with a single-chip microcomputer, wherein the RTU concentrator is further provided with a data acquisition module, a voltage signal acquisition module, a current signal acquisition module, a voltage switching value signal acquisition module and a dry contact signal acquisition module that establish the connection relationship with the single-chip microcomputer, the data acquisition module is used for acquiring equipment sensor data signals for supporting an MODBUS RTU protocol, the voltage signal acquisition module is used for acquiring sensor data signals for supporting 0-10V voltage output, the current signal acquisition module is used for acquiring sensor data signals for supporting 4-20MA current output, the voltage switching value signal acquisition module is used for acquiring sensor switching value signals forsupporting switching value output, and the dry contact signal acquisition module is used for acquiring sensor dry contact signals for supporting dry contact signal output. The system is advantaged inthat a problem of a single sensor protocol access type is solved, and real-time monitoring of the equipment managed by a property unit can be achieved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of equipment management, in particular to an equipment management device and system compatible with multi-sensors based on the Internet of Things. Background technique [0002] The property management system is an indispensable part of the modern residential area. Usually, the property company is the main body of equipment management implementation, and monitors and maintains various equipment and facilities such as water and electricity in the managed area. In the traditional technical solution, it is usually manual operation, the work is very cumbersome and requires a lot of manpower, material resources and financial resources, which greatly wastes the resources of the community property. However, in the era of manual operation, these specific items need to be recorded manually, which is not only troublesome, but also often makes mistakes, which brings a lot of inconvenience to th...
