System and method of remote environmental protection sewage discharge monitoring

Abstract

The present invention discloses a system and method of remote environmental protection sewage discharge monitoring. Water quality information at a monitoring point is acquired by a PH sensor, a COD detector and a flowmeter. Data information is acquired by a system supply voltage sensor, a district network voltage sensor and a flowmeter. When the system supply voltage is zero detected by the system supply voltage sensor, the UPS power supply supplies power. If the information of the normal district network voltage at the monitoring point of the district network voltage sensor and the increased amount of sewage discharge at the monitoring point of the flowmeter is obtained at the same time, a discharge phenomenon under the table is judged. When a failure happens on site, a specially-produced breaker is released and tripped, and a bridge sampling switch emits an alarm signal. After a PLC processor acquires information of water quality, discharge under the table and the on-site failure, the information of water quality, discharge under the table and the on-site failure is transmitted to a monitoring center through a GPRS module, and data analysis and processing are performed in the monitoring center. According to the invention, the real time monitoring of sewage parameters, such as the discharge amount of sewage, COD values, PH values and the like, conditions of discharge under the table and on-site failure may be realized.

Description

technical field [0001] The invention relates to a monitoring system for industrial sewage discharge, in particular to a remote environmental protection anti-stolen discharge and discharge fault monitoring method and device, which are used to realize real-time monitoring of enterprise sewage discharge, sewage sneaky discharge and on-site faults. Background technique [0002] Water pollution is one of the main environmental problems facing our country, and industrial wastewater is the main cause of water pollution. With the development of my country's industry, the discharge of industrial wastewater is increasing day by day. After the industrial wastewater that does not meet the discharge standards is discharged into the water body, it seriously pollutes the water resources. [0003] Most of the current automatic monitoring systems for sewage discharge are a comprehensive online automatic monitoring system composed of modern sensing technology, automatic detection and control ...

Problems solved by technology

However, the current automatic monitoring system is difficult to effectively monitor illegal discharges, making the phenomenon of illegal discharges very rampant without reasonable punishment

Moreover, the on-site fault monitoring part of the current automatic sewage discharge monitoring system is not perfect. When the sewage valve is blocked and stopped, the overcurrent fault or the overload, short circuit, undervoltage and other faults of the power circuit will cause the circuit breaker to trip. , and the site is unattended, it will cause the monitoring system to stop working, causing the monitoring system to be paralyzed and the environment damaged
