Description
Technical field
The present invention relates to a kind of digital display instrument dial plate identification device.
Background technology
Digital instrument is most common parameter outut device in commercial production, detection process, is widely used in industry-by-industry measurement system. The automatic identification technology of instrument can continue monitored parameter change, and especially at some as in the systems such as power monitoring, in order to realize the function of unmanned, automatic alarm, instrument digital identification technology just seems of crucial importance. At present, most meter character real-time identifying systems adopt image acquisition, pretreatment, segmentation, four steps of identification, and this system complex, realization difficulty, accuracy rate is not high.
Summary of the invention
It is an object of the invention to provide a kind of quickly, accurately identify the digital display instrument dial plate identification device of instrument dial plate parameter.
The digital display instrument dial plate identification device of the present invention, forms including governor circuit, power management module, LCD display module, photosensitive circuit module, switch key, PC communication interface and digital display type instrument dish. it is characterized in that power management module is connected with governor circuit, is connected with digital display instrument dial plate, switch key again through governor circuit, provide power supply for digital display instrument dial plate identification device and manage power supply, governor circuit and digital display instrument dial plate, photosensitive circuit module, LCD display module, PC communication interface is connected, the pa-rameter symbols of instrument dial plate is judged by the change of the light of light sensitive diode sensing digital display instrument dial plate pa-rameter symbols reflection in photosensitive circuit module, when the light of instrument dial plate pa-rameter symbols reflection is more many, the voltage of the more little output of light sensitive diode resistance is more big, comparator in photosensitive circuit module compares the height of voltage and converts voltage to low and high level, low and high level is identified processing by governor circuit, again the data after process are shown on screen by LCD display module, it is connected with computer by PC communication interface, instrument dial plate real time data is sent to computer, thus realizing digital display instrument dial plate data automatic identification, Computer Storage and process data.
The invention has the beneficial effects as follows: the present invention provide a kind of quickly, accurately identify digital display instrument dial plate pa-rameter symbols, by photosensitive circuit module identification instrument dial plate pa-rameter symbols, the output signal of photosensitive circuit module is processed by governor circuit, again the data after process are shown on the lcd screen, support online to be uploaded in intelligence system by data simultaneously, realize digital display instrument dial plate data automatic identification, Computer Storage and the digital display instrument dial plate identification device processing data.The present invention is a kind of rational in infrastructure, simple to operate, product that discrimination is high, has bigger market value.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of digital display instrument dial plate identification device.
Detailed description of the invention
A kind of digital display instrument dial plate identification device, as shown in Figure 1, forms including governor circuit, power management module, LCD display module, photosensitive circuit module, switch key, PC communication interface and digital display type instrument dish. It is characterized in that power management module is connected with governor circuit, is connected with digital display instrument dial plate, switch key again through governor circuit, provide power supply for digital display instrument dial plate identification device and manage power supply; Governor circuit is connected with digital display instrument dial plate, photosensitive circuit module, LCD display module, PC communication interface, by photosensitive circuit module identification instrument dial plate pa-rameter symbols, the output signal of photosensitive circuit module is processed by governor circuit, again the data after process are shown on screen by LCD display module, it is connected with computer by PC communication interface, instrument dial plate real time data is sent to computer, thus realizing digital display instrument dial plate data automatic identification, Computer Storage with process data.
Below by using method, further set forth the structural relation of the present invention: photosensitive circuit module is placed on digital display instrument dial plate by (1); (2) power management module of digital display instrument dial plate is corresponding to governor circuit power supply connects; (3) turning on the power switch, instrument dial plate pa-rameter symbols is identified by photosensitive circuit module; (4) the output low and high level of photosensitive circuit module is processed by governor circuit, and in real time the data of collection is shown in lcd screen and is uploaded to PC.
