Project background
In recent years, with the increasing maturity of frequency conversion speed regulation technology, its remarkable energy-saving effect and reliable and stable control mode have been widely used in water supply systems. The variable-frequency constant pressure water supply system applies stepless speed regulation to the pump motor. According to the water consumption and water pressure changes, it automatically changes the pump speed to keep the water pressure constant through microcomputer detection and calculation to meet the water demand. It is the most advanced and reasonable energy-saving water supply system at present. With programmable controller, the program is flexible and changeable, with high precision, strong reliability, multiple functions and fast response. The water pumps are soft started, which extends the service life of the equipment and eliminates the impact of starting current on the power grid. The biggest feature is a set of equipment with double constant pressure control, which can be used for public life and fire protection, saving investment for users. And one machine can be used for two purposes, which greatly improves the use efficiency. However, the control devices generally have such shortcomings as blocked information communication, manual inspection, regular clocking, failure can not be found in time, alarm can not be given in advance, low efficiency, difficult management, and many failures.
practical application
A Siemens PLC, frequency converter, water pump and other equipment are installed on the project site. The PLC completes the logic control, collects the effective data of the PLC through our dark horse Internet of Things GYZT-D100-4GA cloud gateway, and then our cloud platform summarizes the data and displays them in a centralized manner, with large screen display monitoring, electronic billboard and mobile phone APP screen display, and SMS WeChat alarm WeChat small program monitoring. The real-time, daily, weekly and monthly collected data can be quickly compared and analyzed, and intelligent decisions can be made according to the analysis results to achieve the purpose of energy conservation and emission reduction.
This case uses our company's industrial Internet of Things gateway modbus protocol gateway GYZT-D100, which not only realizes the remote data collection of pressure and flow, but also uses the networking function of PLC industrial control gateway to achieve big data communication with the Blackhorse Cloud platform.
GYZT-D100 is a super powerful 4G IoT cloud box, PLC cloud box, PLC cloud gateway, 4G cloud gateway and industrial control gateway. It can complete the remote debugging of Siemens PLC, the remote control of Siemens PLC, the remote monitoring of Siemens PLC, the remote APP of Siemens PLC, as well as the communication and debugging of various brands of PLC, such as Xinjie PLC remote, Yonghong PLC remote, Mitsubishi PLC remote, Delta PLC remote and Omron PLC remote.
Project advantages
1. The Heima GYZT-D100-4GA equipment can have multiple slave stations, reducing the user's equipment cost. The equipment is an industrial grade product, which is resistant to high temperature and low temperature, and can work under extreme conditions.
2. The cloud platform can provide big data engine, large screen display monitoring, electronic signage and mobile phone APP screen display and SMS WeChat alarm WeChat applet monitoring, which can display and record instantaneous traffic and monthly traffic in real time The annual flow, etc. can be summarized into tables or curves in the background according to these data, which is more convenient for users to fully understand the operation of the system.
3. The PC side and APP side data are synchronized in real time. The dark horse configuration cloud platform also provides users with management, facilitating enterprises to better manage projects.
