A Low Power Consumption Environmental Monitoring System

Abstract

The invention relates to a low-power-consumption environment monitoring system comprising a high-capacity lithium battery and a PCB. Unit external interfaces are power supply, analog output, alarm output and modbus communication interfaces. The PCB is designed in a relatively independent mode and the PCB and the lithium battery can be arranged together or the PCB can be arranged separately; and the power supply with the voltage of 9 to 36 V is provided. In order to improve universality of the module, the functional unit employs the modularized design and the PCB employs the way of combination of a mother board with an expansion board. According to a using demand, the corresponding function modules are inserted into plugging elements of the mother board. The system has the following beneficial effects: with the embedded technology, multiple elements are integrated to one circuit board and a cuttable, low-consumption, all-weather, high-performance environment monitoring solution is provided. Besides, the 4-to-20-mA output is employed for external interaction; the isolation type optical relay can be connected with the medium-and-low-power load; the standard modbus RTU and the Modbus TCP carry out communication; seamless integration with systems like the industrial PLC or DCS is realized conveniently; and the system has the good application and popularization value.

Description

technical field [0001] The invention relates to the monitoring field, in particular to a low-power consumption environment monitoring system. Background technique [0002] Part of the special equipment is monitored or recorded during the casting process and the use of the environment to ensure product quality and facilitate maintenance. The information that needs to be monitored or recorded includes the casting equipment and plant environmental conditions, transportation conditions, usage conditions, environmental conditions, etc. . The basic measurement elements of the environmental monitoring module include: temperature, humidity, dew point; other monitoring elements include: dust, noise, X / Y / Z three-axis vibration (acceleration), magnetic field strength, lithium battery power, etc. [0003] There are relatively large defects in the monitoring system of the prior art, mainly reflecting that each monitoring system is not uniformly monitored and used, and most of them are s...

Problems solved by technology

[0003] There are relatively large defects in the monitoring system of the prior art, which mainly reflects that each monitoring system is not uniformly monitored and used, and most of them are single independent systems, which consume a lot of energy and use costs.
