Embodiment Construction
[0042] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0043] The instrument data collection method provided in this application can be applied to filtering equipment. The meter data collection method collects the dial image of the meter of the filtering device periodically, and then acquires the dial reading corresponding to the dial image according to the dial image. The local control terminal of the filter device can control the work of the filter device according to the dial reading after obtaining the dial reading.
[0044] In one embodiment, such as figure 1 As shown, a method for collecting instrument data is provided...

An instrument data acquisition method includes periodically acquiring a dial image of that meter, periodically acquiring a dial image of the dial, periodically acquire a dial image of the dial, periodically acquiring a dial image of the dial, periodically acquiring a dial image of the dial, periodically acquiring a dial image of the dial. Obtaining a dial reading corresponding to the dial image according to the dial image; according to the dial reading, an apparatus having the meter is controlled. In the instrument data acquisition method, an image acquisition device is used to acquire a dialimage of a mechanical instrument, and the dial image is sent to a server to perform recognition processing on the dial image to obtain a dial reading. The control module may receive a dial reading tocontrol operation of the device. The advantages of using mechanical instruments instead of electronic instruments are that the mechanical instruments have high reliability of reading and are not easyto damage and stable. At the same time, the cost of mechanical instruments is low, which can save production cost. By collecting the dial image of the mechanical instrument and converting the image data, the dial image of the mechanical instrument can be converted into digital display mode, which is convenient for users to read.
Description
technical field [0001] The present application relates to the technical field of filtration, in particular to an instrument data collection method, device and filtration system. Background technique [0002] With the improvement of the quality of life, water purifiers are more and more applied to people's production and life. Usually, a pressure gauge is installed in the filter equipment of the water purifier to detect the pressure of the water pipe. The traditional way to detect water pipe pressure is to use electronic instruments to transmit data to the controller through current or voltage signals, and the controller outputs the measurement value of the instrument through analog / digital conversion. During the process of realizing the traditional technology, the applicant found that the reliability of the electronic instrument is not high, and the situation of damage or inaccurate measurement often occurs. Contents of the invention [0003] Based on this, it is necessa...
