Description

Temperature Monitoring Device

technical field

The invention relates to a monitoring device, in particular to a temperature monitoring device.

Background technique

With the improvement of the industrialization of human society and the deepening impact of various social activities on the environment, the monitoring of environmental temperature information and the collection and analysis of related data have become particularly urgent. Early environmental temperature monitoring equipment was collected manually. This method has the disadvantages of low efficiency, poor data accuracy, and high construction and operation costs.

Contents of the invention

In order to solve the above problems, the object of the present invention is to provide a temperature monitoring device with low cost, high performance and high degree of intelligence.

In order to achieve the above purpose, a temperature monitoring device is mainly composed of a power amplifier, a high-gain antenna, a Zigbee communication system module, a solar battery and a lithium battery power supply unit, a temperature monitoring device, and a single-chip microcomputer.

The power amplifier is connected to the single-chip microcomputer through the line, the high-gain antenna is connected to the single-chip microcomputer through the line, the Zigbee communication system module is connected to the single-chip microcomputer through the line, the solar battery and the lithium battery power supply unit are connected to the single-chip microcomputer through the line, and the temperature monitoring device is connected to the single-chip microcomputer through the line.

The monitoring network of this design includes a DTU (data transfer unit) and multiple temperature sensor nodes. The temperature monitoring device converts the physical value of the environmental parameters into an analog signal in the form of voltage or current. The CPU of the temperature monitoring device node converts the analog signal sent by the sensor into a digital signal, and sends the temperature data to the DTU through the Zigbee communication system module. DTU packs the temperature information sent by all temperature monitoring device nodes in the monitoring area, and sends all temperature data in the monitoring area to the host computer software through the GPRS data remote transmission module of DTU. The upper computer software has the function of displaying the temperature information of the monitoring area in real time, and at the same time has the function of modifying the node parameters of the temperature monitoring device in the monitoring area.

This project is based on the new technology of the Internet of Things, through a DTU (data transmission unit) and several temperature sensor nodes with Zigbee wireless communication functions to form a star monitoring network structure. The point-to-point stable communication distance of Zigbee wireless communication is 2 kilometers. The coverage area of a single area is theoretically a circular area with a radius of 2 kilometers, which is about 12 square kilometers. In this way, multiple monitoring networks can be combined to complete the entire monitoring area. Then, the temperature data of the entire area monitoring point can be sent to the server client software through the GPRS data remote transmission module of the DTU of the respective monitoring network, thereby realizing wide-area environmental monitoring. At the same time, the temperature sensor node has the functions of low power consumption sleep and lithium battery charging, which ensures continuous work for a long time and improves work efficiency.

The temperature monitoring device of the invention has the characteristics of low cost, high performance and high intelligence.
