Project background
With the rapid development of national industry, the pollution problem of water environment follows. Now, people have made it clear that wastewater and sewage are not allowed to be discharged without organization. In order to put an end to unorganized discharge, enterprises are equipped with professional environmental protection purification equipment to convert unorganized discharge into organized discharge, so as to achieve standard discharge. In the case of organized discharge, the quality of wastewater shall meet the relevant limit requirements in the national pollutant discharge standards, local pollutant discharge standards and industrial pollutant discharge standards. The level of automation in sewage treatment plants is not high. Most of them are limited to single point monitoring or LAN monitoring. Due to the disunity of communication protocols, data cannot be shared. The traditional configuration software cannot meet the needs of modern distributed management, and it is difficult to meet the needs of modern cities for sewage treatment systems. When the equipment fails, the dispatcher needs to send instructions to dispatch personnel. The degree of automation is not high, Waste a lot of manpower and material resources. When the system fails, it is difficult for dispatchers to find the fault in time.
practical application
There is a special wastewater collection tank on the customer's site. The wastewater is neutralized and purified by professional wastewater treatment equipment before being recycled, which not only reduces environmental pressure, but also saves costs. The equipment adopts the GYZT-HD2N-20MR controller of the Black Horse Internet of Things, and then develops a complete set of control logic in the PLC, which realizes the automatic control of wastewater treatment and circulation, and communicates all the internal data of the PLC to the Black Horse configuration cloud platform through the 4G communication function integrated with the PLC itself. The whole process monitoring of equipment status, sewage data and pure water recycling is realized.
The dark horse configuration cloud platform supports MQTT protocol and JSON protocol transmission, supports third-party hardware access, can interface with most Internet of Things hardware on the market, and easily realizes data collection and equipment control in industrial control, environmental protection and other fields. The cloud platform supports cloud configuration, and users can freely build system interfaces as needed. Even non professionals who do not know programming can freely and quickly build a suitable Internet of Things system. The cloud platform uses the B/S architecture, supports PC browser, industrial large screen display and electronic signage display functions, mobile APP, WeChat official account, etc., to meet users' needs in different scenarios.
The dark horse configuration cloud platform collects PLC or instrument data through the 485 port of the dark horse gateway module, and supports various mainstream PLCs. It collects PLC or instrument data through the network port of the dark horse module, and can directly connect the switch signal and analog sensor to the cloud platform. Through OPC protocol, it can connect the upper computer SCADA and DCS data, access the black horse cloud platform, support the GPS positioning of the base station, and support the webcam to access the cloud platform.
The dark horse configuration cloud platform supports independent configuration and template configuration. No user programming is required. By dragging and drawing the operation screen of the device through simple configuration controls, and then binding the data of the device, visual management of the field device can be realized, including real-time data display, process operation flow chart, remote control, device alarm records, etc., which can be viewed remotely on the PC or mobile phone. It is convenient to know the operation status of equipment and projects in real time intuitively and vividly anytime, anywhere.
Equipment advantages
1. GYZT-HD2N-20MR cloud PLC equipment is configured with 8-way AD analog quantity collection, 12 way switching value input and 8-way output, integrated with 4G networking function, which reduces 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. Simple installation and convenient debugging. After the equipment is installed on the site, input the identification code on the field equipment on the background software for remote debugging.
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.
