The station house intelligent fusion terminal monitoring method comprises the following steps:
the method comprises the following steps: assembling hardware, namely assembling a station terminal DTU, an environment monitoring terminal, an electrical equipment state monitoring terminal, an electrical equipment terminal, a video monitoring terminal and a communication gateway through a bearing operation box; after being assembled, the station house is arranged in a station house to be supervised through a bearing operation box; installing a plurality of peripheral equipment of the environment monitoring terminal, the electrical equipment state monitoring terminal and the video monitoring terminal at preset working positions; finally, the DTU of the station terminal is respectively in data connection with the environment monitoring terminal, the electrical equipment state monitoring terminal and the video monitoring terminal through the communication gateway, and is also in data connection with the main station monitoring platform through the data communication device;

Because electrical equipment is numerous in the distribution station room, the life of electrical equipment is influenced by environment humiture greatly, consequently requires to join in marriage the environmental humiture control in the electrical room at reasonable within range. Therefore, the environment temperature and humidity transmitter is arranged in the power distribution room and used for monitoring the environment temperature and humidity value in the power distribution room, and once the temperature is too high or too low, the environment temperature and humidity transmitter can be linked with the air conditioner to refrigerate or heat; once the humidity in the station room is discovered to be too high, the dehumidifier can be linked to dehumidify, so that the temperature and the humidity in the station room are kept in a reasonable range, and the safe, reliable and long-term operation of electrical equipment is ensured. A high-voltage SF6 gas-filled cabinet is arranged in part of power distribution station rooms, and in the operation process, due to the fact that high-voltage discharge is easy to occur during opening and closing, SF6 gas can generate harmful derivatives, and once leakage exceeds the standard, serious influence can be caused on the body health of operation and inspection personnel. Therefore, SF6 and O2 double-gas monitoring transmitters are needed to be configured to monitor the concentration of SF6 and the content of O2 in a station room, once the concentration of SF6 exceeds the standard or the content of O2 is low, the fan is started to ventilate immediately, and sound-light alarm is started and alarm information is pushed to a DTU (data terminal unit) at the first time. Because various cables in the cable trench of the power distribution station are numerous, and the cable trench is relatively damp and hot, therefore, harmful gases such as ozone and TVOC (transient overvoltage protection circuit) can be generated frequently, the gases flow into a power distribution station room through a cable cover plate, and can cause serious influence on the health of transportation and inspection personnel, therefore, an O3 monitoring transmitter and a TVOC harmful gas monitoring transmitter are necessary to be configured, once the concentration of the harmful gases exceeds the standard, a fan is started for ventilation and air exchange immediately, and sound and light alarm is started for the first time and alarm information is pushed upwards.
In addition, the number of low-voltage switch cabinets in the power distribution station room is large, and the low-voltage switch cabinets are also places where faults frequently occur in the operation and inspection process. Before the switch cabinet breaks down, the phenomenon that condensation in the cabinet seriously influences the insulation distance, the load is too large or the contact is poor to cause too high temperature of the contact and partial discharge is generated in the switch cabinet due to insulation damage is more or less obvious. Therefore, the drainage type electric cabinet dehumidifier is additionally arranged in the cable chamber of the switch cabinet, the dehumidification in the switch cabinet is realized by adopting an electronic condensation principle, the moisture in the cabinet is really discharged out of the cabinet, the absolute humidity in the cabinet is reduced, and the phenomenon that the insulation performance is influenced by condensation generated due to overhigh humidity in the cabinet is prevented; a passive wireless contact temperature measuring transmitter is added at the contact for monitoring the temperature measurement of the contact, the battery does not need to be replaced, the limitation of the minimum primary current is avoided, and the temperature measurement data is transmitted to a contact temperature measurement monitoring device arranged on the cabinet surface of an instrument room in a wireless mode; a switch cabinet partial discharge monitoring transmitter is arranged on the side face inside the switch cabinet and used for monitoring the partial discharge condition inside the switch cabinet. Once the temperature and humidity in the switch cabinet exceed the standard, the temperature of the contact is too high or the partial discharge strength exceeds the standard, the acousto-optic alarm is started at the first time and alarm information is pushed upwards.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
