How to convert RS485 temperature and humidity sensor output signal into network signal?
At present, various intelligent sensors are widely used in the industrial control field for production process monitoring. It is a very necessary link to transmit the data monitored by the intelligent sensors to the monitoring computer for display and analysis. Currently, most of the data communication interfaces are RS232, RS422, RS485. We can convert these interfaces into Ethernet ports, or into wireless signals such as GPRS/4G, and then transfer the collected data to the IoT cloud through the concentrator Platform or local platform. Among them, RS485, as a widely used communication standard, is widely used in data concentrators. So what is RS485? RS485 is a serial data interface standard proposed in 1983 by the American EIA company in order to make up for the short communication distance and low transmission speed of RS-232. RS485 uses differential transmission, also called balanced transmission. , Has a relatively high noise suppression capability, the maximum transmission distance is about 1200 meters, the maximum transmission rate is 10Mb/s, and multi-point, two-way communication capabilities are added, so RS-485 has become the preferred serial interface. So how to convert RS485 data into network data for remote transmission? Then another device is needed: a concentrator. The concentrator is a very important part of the data transmission network, it is the data transmission device. It is the central management and control equipment of the remote data acquisition system, and is responsible for regularly reading data from the collector, system command transmission, data communication, network management and other functions. All kinds of collected data are first connected to the concentrator located at each collection point through the RS485 interface (via twisted pair), and then the concentrator is connected to the GPRS transparent data transmission terminal through the RS232/RS485 interface. Through the GPRS transparent data transmission terminal built-in embedded processor, the data is processed, the protocol is packaged and then sent to the GPRS network, and then transmitted to the data center through the GPRS network, realizing the real-time online connection between the data of each collection point and the data center system. The concentrator can also be directly connected to each collector through the RS485 interface, which can support a single collector or multiple collectors at the same time, so as to realize the storage and preprocessing of the data collected by each collector, and collect the data. The data is transmitted to the center in real time; at the same time, the concentrator can also transmit the remote control instructions sent by the center to the control module to control the concentrator. According to different output signal types, there are three types of concentrators: GPRS, WIFI, and Ethernet according to different signal transmission. GPRS concentrator GPRS concentrator solves the difficulty of self-built network on site with the help of the signal coverage of China Mobile or China Unicom. Wireless transmission is used to upload data to the monitoring center or monitoring software equipment through GPRS/4G communication. There is no wiring on site and unlimited transmission distance. Only a mobile phone data card is required. This is also the most significant feature of GPRS concentrators. WiFi concentrator The WiFi concentrator uses wireless WiFi to transmit data, and only a general wireless router is required on site, which saves the cost of on-site wiring and hidden wiring hazards. Upload data to the monitoring center or monitoring software equipment via WiFi wireless. Ethernet Concentrator The Ethernet concentrator uses Ethernet to transmit data, which is suitable for collecting data from multiple points in one space, and uploading to the network through a concentrator. The overall equipment cost of this solution is low. . Widely used in computer room monitoring systems, power systems, industrial automation control, security engineering, medical and health monitoring, agricultural monitoring systems, energy consumption monitoring systems, environmental monitoring systems, smart homes and other fields.
