Intelligent monitoring terminal for station environment and harmful gas leakage

Abstract

The invention relates to an intelligent monitoring terminal for station environment and harmful gas leakage, which comprises an RS485 bus interface connected with a sensor, the output end of the RS485 bus interface is in data connection with an actuator through a monitoring terminal, and the monitoring terminal comprises: a UPS module which is used for automatically detecting the working state of the power supply module, wherein when the power supply module is normal, the UPS is in a backup state, and meanwhile, charging management is carried out on a battery in the machine, and when the power supply module is abnormal, the UPS immediately supplies the electric energy of a battery in the UPS to the intelligent terminal and provides 24V DC power supply to the intelligent terminal directly, so that the load is maintained to work normally; and a main control module which is used for completing acquisition and processing of data analog quantity and switching quantity, operation and judgment of various control criteria, and then generating corresponding control outlets, sending signals, performing communication transmission and the like. The intelligent monitoring terminal has the beneficial effects that coordination and switching of execution parameters are effectively controlled, condensation can be effectively controlled, energy can be saved to the maximum extent, and safe and normal long-term operation of power equipment is ensured.

Description

technical field [0001] The invention relates to the technical field of gas detection systems, in particular to an intelligent monitoring terminal for station environment and harmful gas leakage. Background technique [0002] The gas detection system is generally divided into the control part, the sensor part, and the management platform part, which can realize remote unattended, real-time data return, over-limit alarm, equipment linkage, data analysis and other functions. The existing gas monitoring system has a single function. It only collects data from the external environment and performs corresponding corresponding processing through the actuator. If the system encounters a power failure, the processor will lose corresponding data. There is no corresponding automatic detection function, and the module does not have automatic detection. The working status of the power supply module cannot guarantee the safety of the system. At the same time, due to the large number of el...

[0002] The gas detection system is generally divided into the control part, the sensor part, and the management platform part, which can realize remote unattended, real-time data return, over-limit alarm, equipment linkage, data analysis and other functions. The existing gas monitoring system has a single function. It only collects data from the external environment and performs corresponding corresponding processing through the actuator. If the system encounters a power failure, the processor will lose corresponding data. There is no corresponding automatic detection function, and the module does not have automatic detection. The working status of the power supply module cannot guarantee the safety of the system. At the same time, due to the large number of electronic components around the station, it will generate a large electromagnetic force, which will cause large electromagnetic interference to the device and affect the collection and transmission of data. , in the long-term data transmission, the interference source and the part susceptible to interference are influenced by each other on the circuit, and the input and output electrical signals cannot be well isolated, which leads to the failure of the measurement and control device to maintain signal contact with the field, making the signal possible. There is an interruption, which affects the normal use of personnel
