[0002] At present, many power plants are carrying out large-scale modernization transformation. In the upgrading and reconstruction process of the power plant, the sewage treatment reconstruction is particularly important. In the sewage treatment system, all sewage discharge points are discharged into the same sewage pool, and the sewage in the sewage pool is treated centrally, therefore, it is necessary to coordinate the start and stop of the sewage discharge pump at the sewage discharge point to ensure that the amount of sewage in the sewage pool is appropriate.

[0003] In the upgrading and reconstruction process of the sewage treatment system, it is necessary to increase or reduce the sewage discharge point. The original sewage discharge pump adopts local interlocking control, and the liquid level switch and the pump are interlocked to start and stop, and there is no sewage discharge pump and remote signal of the local monitoring instrument. Only a pressure gauge is arranged at the outlet of the pump for checking the working condition of the pump during local inspection, and it cannot be monitored uniformly in the centralized control center. The original sewage discharge point is far away from the existing control system of the power plant, and if the sewage discharge pump and the remote monitoring instrument are increased, long-distance signal cable needs to be directly buried and laid, which causes large-area excavation in the plant area and large engineering quantity.

[0004] Therefore, a device capable of realizing centralized monitoring and linkage control of the instrument state of each sewage point is needed in the upgrading and reconstruction of the power plant. CONTENT OF THE UTILITY MODEL

Embodiment

[0030] After the sewage (a plurality of sewage discharge points) of the power plant is discharged into the same sewage pool 1, the sewage is treated. Due to the later power plant reconstruction, a new sewage discharge point is added. Considering that the sewage discharge amount of the original sewage discharge point of the old plant is small, the running requirement of the power plant can be met as long as the new sewage discharge point and the original sewage discharge point of the old plant do not discharge sewage at the same time (about 1 hour), that is, the sewage pool 1 does not overflow.

[0031] In order to facilitate operation, two sewage discharge pump 3 outlet pressure gauges 4 are arranged at the original sewage discharge point of the old plant, which are used to monitor whether the sewage discharge pump 3 is running. The original sewage discharge pump 3 of the old plant adopts local interlocking control, and the sewage discharge pump 3 is started and stopped through the liquid level switch, and there is no remote signal of the sewage discharge pump 3 and the local monitoring instrument. Only the pressure gauge 4 is arranged at the outlet of the sewage discharge pump 3, which is used to check the working condition of the pump during local inspection.

[0032] Because the original sewage discharge point of the old plant is far away from the existing control system of the power plant, if the sewage discharge pump 3 and the remote monitoring instrument are added, long-distance signal cable needs to be directly buried and laid, which causes large-area excavation in the plant area and large engineering quantity. The original sewage discharge point of the old plant is provided with a video monitoring system, which is used to monitor whether the sewage overflows.

The camera 5 has automatic focusing and automatic light adjustment functions to adapt to different lighting conditions and collect different pointer positions of the on-site pressure gauge 4.

[0037] 2. An image processing unit:

[0038] An instrument panel monitoring and recognition system SJPC01 module is embedded in the Ai camera 5 to pre-process the collected image, including image graying, noise reduction, edge detection and other operations, so as to improve the image quality and highlight the instrument panel features. The image processing algorithm of neural network is used to analyze the reading of the instrument panel, and according to the set pressure value, the on-off output value of whether the sewage discharge pump 3 is running is given.

[0039] 3. An on-off output unit:

[0040] In order to facilitate signal transmission, the Ai camera 5 transmits the on-off value of whether the sewage discharge pump 3 is running to the display of the centralized control center (in the same building as the monitoring of the newly added sewage discharge point) through the video monitoring network.

[0041] 4. A linkage unit with a newly added sewage discharge point:

[0042] The centralized control cabinet 7 is wirelessly connected with the camera, collects the on-off value of whether the sewage discharge pump 3 is running output by the camera on-site instrument reading recognition module, sets and introduces a joint control circuit inside, and realizes interlocking between the sewage discharge pumps 3; when the sewage discharge pump 3 of a certain sewage discharge point is started, the relay of the sewage discharge pump 3 of the certain sewage discharge point is powered, and the sewage discharge pumps 3 of other sewage discharge points are not powered.
