Platform for controlling opening degree of water inlet valve of heater

Abstract

The invention relates to a platform for controlling an opening degree of a water inlet valve of a heater. The platform for controlling the opening degree of the water inlet valve of the heater comprises a frequency division duplex communication interface, an automatic control switch, a curve matching device and an automatic control switch, wherein the frequency division duplex communication interface is used for receiving local air temperature wirelessly sent by the meteorological department; the automatic control switch is used for receiving the local air temperature and implementing automatic on-off control on the water inlet valve of the heater based on the local air temperature; the curve matching device is used for connecting all edge pixels so as to obtain multiple closed curves anddividing a graying image into multiple corresponding patterns based on the multiple closed curves; when a pattern exceeding the limit of the matching degree of a preset personnel standard image exists, a personnel existence signal is sent out, and otherwise, a personnel inexistence signal is sent out; and the automatic control switch is used for completely switching on the water inlet valve of theheater when the local air temperature is lower than or equal to a preset air temperature threshold value and the curve matching device outputs the personnel existence signal. Through the platform forcontrolling the opening degree of the water inlet valve of the heater provided by the invention, the electronized control of the opening degree of the water inlet valve of the heater is realized.

Description

technical field [0001] The invention relates to the field of valve control, in particular to a heater water inlet valve opening control platform. Background technique [0002] In the water passing system of the water turbine, according to the needs of the operation and maintenance of the hydropower station, corresponding gates or valves are installed at different positions. Usually, the valve installed in front of the volute of the water turbine is called the water inlet valve. [0003] The water inlet valve is also used in household equipment such as heaters to control the return water speed in the heater, thereby indirectly controlling the heating efficiency of the heater. Contents of the invention [0004] In order to solve the technical problem that the opening of the water inlet valve of the heater requires manual operation, the invention provides a control platform for the opening of the water inlet valve of the heater, which implements adaptive edge enhancement proc...

Problems solved by technology

[0004] In order to solve the technical problem that the opening of the water inlet valve of the heater requires manual operation, the invention provides a control platform for the opening of the water inlet valve of the heater, which implements adaptive edge enhancement processing through the edge analysis results of the image content; The contrast-enhanced image is subjected to high-precision image simplification to obtain the image to be analyzed, which is convenient for subsequent image recognition and image detection; a custom-made dust measuring instrument is used to measure the relative attenuation rate of parallel monochromatic light based on the common sense of detection. Detect the existence of dust particles, on this basis, use the image analysis mode to confirm the dust particles, and use the ultrasonic dust removal mode to remove the dust particles directional; use the automatic control switch to control the heater based on the local temperature and on-site personnel The corresponding opening control of the water inlet valve
