Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1, the present invention is a kind of transformer load harvester, comprise box body, in described box body, there is an acquisition system module, described acquisition system module comprises single-chip microcomputer, storer, communication interface, power module and sensor assembly, described storer, communication interface and power module are connected with described single-chip microcomputer, and described single-chip microcomputer is connected with the sensor assembly that can survey reometer size of current; It is MSP430 single-chip microcomputer that described single-chip microcomputer adopts model; Described sensor assembly is the angle displacement sensor that can survey ammeter pointer deflection angle; Described communication interface is removable USB flash disk interface.
Simple structure explanation of the present invention:
1, inspection instrument integrated box volume: 10CM*10CM*3CM;
2, installation site: inspection instrument integrated box is fixed on to JP cabinet inner bottom part;
3, integrated box power supply: adopt 2300mAh battery three to save 1.5V*3 power supply, estimate that battery life is three months;
4, single-chip microcomputer type selecting: in order to extend power-on time as far as possible, select low-power scm MSP430, separately add support circuit element;
5, sensor: adopt angle displacement sensor, measure ammeter pointer deflection
6, principle of work:
1, by installation of sensors at reometer panel board, regularly image data
2, be transferred to single-chip microcomputer and store (needing programming)
3, use USB flash disk to download (needing programming) to single-chip microcomputer storage data
4, transferring data to PC Microsoft Excel is analyzed.
After system boot, arrange by setting timing, give an order at special time, open pin, carry out signal and receive storage work.Sensor is the primary link that realization is measured and controlled, and system is carried out simulating signal by the output quantity after sensor conversion by operational amplification circuit and amplified processing, by A/D converter, simulating signal is converted to digital signal afterwards.
Be transferred to PC in order to realize data from Single Chip Microcomputer (SCM) system, we have comprised a USB serial line interface, a USB transceiver and have deposited program and the RAM storer of data in this Single Chip Microcomputer (SCM) system, have comprised a USB interface, an I in input system
2c and 24 I/O interfaces.
Program realizes data by such mode and downloads: controlled and opened peripheral hardware driving by order, by carrying out CreateFile() function acquisition handle, then realize slave driver acquisition data by DcviceIOControl () function.This two function can obtain from universal driver.
The present invention carries out Based Intelligent Control by single-chip microcomputer, install an angle displacement sensor outward additional at substation transformer panel board, rely on like this acquisition system to realize timing data sampling, transfer data to computer by external USB flash disk, carry out data analysis by computer software again, find and have hidden danger transformer, carry out Rectification of hidden dangers, the present invention is simple in structure, easy to use, reliability is high, to load variations can carry out dynamic auto detection, record with facilitate further analysis and Control transformer load harvester.
