What is the role of the environmental protection meter power management system?
The environmental protection metering and electricity management system can realize the sharing of power data of provincial, city and county three-level enterprises, monitor the entire process of the enterprise's pollution treatment level, and refine the management. Once abnormal situations occur, such as the pollution control equipment is not turned on, pollution control equipment Inefficient operation, unauthorized replacement of monitoring equipment by the enterprise, etc., the monitoring platform will trigger an alarm at the first time, and push it to the executive staff through mobile phone text messages, APPs and other forms.
The environmental protection metering and electricity management system can provide strong scientific and technological support and data support for Hebei Province's air pollution prevention and control work, thereby effectively preventing problems such as stealth of production and production, non-use of pollution control equipment, and non-use of pollution control equipment. On-line monitoring of production processes and pollution control processes of production enterprises to improve environmental supervision capabilities and control pollution from the source.
The meter-by-meter power metering system will verify the operation level of the pollution treatment facility based on the online monitoring data of the sewage discharge node and the current, voltage, and power parameters of the pollution treatment facility, and set appropriate alarm thresholds through the platform management software to provide real-time and accurate information for environmental enforcement. clue. In the event of abnormal situations such as pollution control equipment not turning on as required, inefficient operation of pollution control equipment, unauthorized replacement of monitoring equipment by the enterprise, the monitoring platform will trigger an alarm at the first time, and push it to the executive through SMS, APP, etc. personnel.
Environmental pollution prevention and control focuses on supervision. Li'an Technology focuses on the "source pollution" problem of "pollution control facilities not functioning properly", which is the "source" of enterprises' excessive emissions of pollutants. It adopts modern information technologies such as the Internet of Things, big data, cloud computing, mobile Internet and artificial intelligence to develop environmental protection for environmental protection departments The meter-by-meter power monitoring and monitoring cloud platform is an important part of the automatic monitoring system for pollution sources.
The platform relies on innovative intelligent terminal products such as intelligent IoT circuit breakers to collect real-time data on power consumption of production and electricity consumption of environmental protection equipment, and move the environmental supervision threshold from monitoring enterprise pollution emissions to monitoring enterprise power consumption. The whole process of production, pollution control, and drainage of key gas-related enterprises within the country implements 24-hour monitoring, and implements environmental supervision based on the principle of balance between the total power consumption of the enterprise, the power consumption of production facilities, and the power consumption of environmental protection and governance facilities to ensure that the company's waste gas treatment The facility is operating normally and the pollutants are discharged up to standards.
In terms of smart terminals, Lian Technology independently developed a smart power monitoring terminal with an industrial microprocessor as the core and high processing speed. It provides high-precision three-phase voltage, current, and power measurements. Functions such as value over-limit, temperature protection, etc., can meet the installation requirements of space-intensive plug-in boxes, low-voltage power distribution cabinets, and floor power distribution boxes. It is an online monitoring of project data such as energy consumption management, pollution control facilities distribution supervision, and power operation and maintenance. Ideal for analysis.
The environmental protection meter power monitoring cloud platform has realized the following six functions
01 〠Real-time load monitoring
Real-time collection of electricity consumption data of production facilities and governance facilities of enterprises. Through mobile clients such as mobile phones, you can dynamically monitor the operation of enterprises, workshop equipment, monitoring points at all levels, and view electricity statistics, including production status and equipment status. , Current, voltage, power, power and other real-time monitoring, management and protection. The power and power curves include the set equipment start-stop thresholds. Based on the start-stop thresholds, it is judged whether the production time and the operation time of the pollution control facilities match, and whether there is a time conflict with the production shutdown and production restriction plan.
02, abnormal real-time alarm
The electricity consumption data of the production and pollution control facilities of the enterprise are divided into tables and collected in real time. Through process correlation analysis, over-limit analysis, and start-stop time analysis, it is found that the environmental protection pollution control equipment does not start / stop, abruptly shut down, and decelerate in accordance with regulations. , Low-load operation, idling, frequency reduction and other illegal production and abnormal situations, enterprises illegally replace monitoring equipment and other violations, and at the same time through data analysis can also monitor real-time production restrictions and shutdowns to rectify the operating status of the enterprise. Once an abnormality occurs, the command center platform will trigger an alarm at the first time and push it to the environmental protection executive through the mobile APP.
03, power failure alarm
Li'an environmental protection sub-meter power metering monitoring equipment accurately determines whether the equipment is about to go offline due to a power outage abnormality, and promptly upload a power outage alarm event to remind, and also upload a reminder when a call comes. Allows users to accurately control the offline status and online status caused by incoming calls, as well as supervise the manual offline to check the cause of power failure, and urge timely power transmission.
04, Fine Power Management
The electricity consumption data of the production facilities and governance facilities of the enterprise are divided into tables and collected in real time, and the data is imported into the management center for display and summary comparison, including pollution analysis (counting the amount of pollution produced by the enterprise / industry within a certain period of time), Production reduction and emission reduction analysis (statistical comparison of load on polluting day and non-polluting day, showing power curve in hours), enterprise electricity monitoring (you can query the daily power curve of the enterprise), and energy consumption report (statistical enterprise / industry in The electricity consumption in a certain period of time can be statistically analyzed and ranked by day / month / year to form exportable graphs and data reports), and abnormalities can be found in time, which can not only be used as a basis for analyzing and judging the implementation of environmental protection measures of enterprises It can also provide data support for enterprises to reduce energy consumption.
05.Statistical analysis of data
Judging the start-stop status of production facilities and pollution control facilities based on the related relationship, and comprehensively drawing the conclusion that the equipment is shut down abnormally based on the equipment's main-standby relationship and operation cycle. For monitoring points such as production stoppage and peak shift production, comprehensive analysis and judgment of pollution control facilities operation, production stoppage, production limit, peak cut and other instructions are implemented.
06, mobile APP warning
The environmental protection meter power monitoring cloud platform supports Android and ios system APPs, which is convenient for environmental protection departments to perform industry / enterprise real-time monitoring data query, alarm, fault query, remote control and other functions.
