1. System Overview:
Flow SCADA system, Jin Company data acquisition and monitoring system. Flow measurement is not an isolated system in the production and operation environment of enterprises. It is closely related to the production process management, production quality management, production cost accounting, trade settlement and other links of enterprises, and is mutually based and supportive. Therefore, the traffic data collection and monitoring system
It is a complex automation and information management system.
The SCADA system uses advanced and reliable communication network systems such as 485 network, Ethernet, wireless GPRS, etc
Line data transmission, etc., to achieve data exchange and precise control with on-site instruments. Main application cases include: heat network monitoring, water supply
Network monitoring, sewage monitoring, and various internal energy metering networks in chemical plants.

3/Composition and working principle of flow SCADA system
The SCADA system consists of a flow data collector, system software, server, and client. The flow data collector integrates a flow integrator, communication module, and UPS power supply for the on-site equipment.
The flow data collector collects on-site flow data, and the flow integrator compensates and temporarily stores historical data. At the same time, real-time data is transmitted to the server system software through the communication network.
The system software monitors and controls the on-site situation in real-time, while saving real-time data to a historical database. The complete historical data in the server lays the foundation for functions such as data analysis, report generation, trade settlement, and cost accounting.
The client computer is connected through a local area network or internet network. It can access server data, and various functions such as data viewing, on-site monitoring, and report analysis are completely consistent with server operations.
The composition of the flow SCADA system is shown in Figure 3-1.
4/Introduction to Traffic System Software
The flow measurement monitoring and analysis system software is developed and researched by Weifang Yichuan Electronic Technology Co., Ltd. It inherits the advantages of SCADA system software and innovates in communication methods by combining wireless radio and GPRS/CDMA. Under the flow measurement monitoring and analysis system software platform, users can freely choose between two communication modes. For the convenience of writing, this software is referred to as traffic system software in the following text.
The traffic system software has powerful functions: Over the course of more than 3 years of use, we have continuously improved the software based on feedback from our users. Currently, the traffic system software almost includes all the functions in traffic monitoring. At the same time, this system has strong compatibility and can be compatible with any instrument with serial communication function. Special functions can be developed according to customer needs.
