In order to fight the tough battle of pollution prevention and control, speed up the ecological environment protection, "strictly control environmental protection and promote green development", win the battle of "blue sky, clear water and pure land" in an all-round way, and build a beautiful China, the state has successively issued "On Comprehensively Strengthening the Ecological Environment". In response to national policies, a large-scale production enterprise is ready to conduct real-time monitoring of the operation of pollution source production facilities and pollution control facilities within the enterprise. It can provide technical support for government departments to dynamically and truly grasp the production status of enterprises, determine the implementation of pollution control and abnormal early warning such as production suspension, production restriction, and peak production, and provide technical support for intelligent supervision that requires no wiring and less investment. plan.
In order to solve this problem, a comprehensive smart power consumption supervision solution integrating terminal, gateway and cloud server is required;
An employee of Ebyte, who did not want to be named, designed a power consumption supervision system based on the Lora technical solution according to the characteristics of the existing Lora wireless communication technology. Collect equipment, use sensing technology to collect equipment operating condition data in real time, and then wirelessly transmit the data to the cloud monitoring platform to achieve 24-hour continuous monitoring of the total electricity consumption of the enterprise, the electricity consumption of production facilities, and the electricity consumption of environmental protection facilities. Intermittent whole-process remote monitoring, so that the operation of pollution control facilities can be accurately grasped according to the comparison of the three power consumptions with each other; and it has the characteristics of free wiring and low investment.
The hardware includes lora data transmission module, housing, backplane, power supply, lora gateway, etc.;
Software functions include equipment number grouping, regional exhibition status display, equipment status display, alarm setting, user management, etc.;
The acquisition device transmits the working condition data to the LORA data transmission module at a fixed frequency through UART at regular intervals. The LORA wireless data transmission module uploads the data to the lora gateway, and the lora gateway uploads the data to the corresponding server, and the server organizes and displays the data. , to provide technical support for government departments to dynamically and truly grasp the production status of enterprises, and to determine the implementation of pollution control and abnormal early warnings such as production suspension, production restrictions, and off-peak production.
In this solution, an employee of Ebyte selected Ebyte's E22-400T22S LORA terminal module and E90-DTU (400SL22-4G) LORA gateway after multiple comparisons considering various factors such as module performance and cost performance. , integrated in the electricity monitoring system.
The acquisition device reports the status data to the E22-400T22S through UART at a fixed frequency, the E22-400T22S uploads the data to the E90-DTU (400SL22-4G)lora gateway, and the E90-DTU (400SL22-4G)lora gateway uploads the data to the corresponding The server organizes and displays the data, and provides technical support for government departments to dynamically and truly grasp the production status of the enterprise, determine the implementation of pollution control and abnormal early warning such as production suspension, production restriction, and off-peak production.
The E22-400T22S lora module used in the case has the following characteristics:
Long transmission distance: The transmission distance is 5km;
More cost-effective: E22-400T22S lora module, cost-effective, stable supply, especially at the moment, there is no worry about tight material supply;
Convenience and flexibility: The installation is more convenient and flexible, no complicated wiring operation is required, and it is relatively simple to move and change;
Rich functions: support relay networking, RSSI, LBT, data transparent transmission and other functions;
Low power consumption, power consumption is as low as 2uA in sleep mode;
Small size, easier to integrate;
Customizable: According to the actual needs of customers, specific functions can be customized and developed.
The combination of Ebyte's E22-400T22S lora module and lora gateway effectively satisfies the construction of the enterprise's electricity consumption supervision. In fact, there are many RF modules that can be applied to this solution, including WiFi, Bluetooth, ZigBee, 4G and other technical products series, you are welcome to choose;
Ebyte has also been committed to the development of smart industry, smart home, smart security, smart transportation, smart environmental protection, smart agriculture and other industries.
