Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
See Fig. 1, a kind of irregular area measurement device example structure synoptic diagram of the utility model, comprise crossfoot 1, linear foot 2, microprocessor 3, digital display screen 4, crossfoot 1 is put for landing tee with linear foot 2, crossfoot 1 is that four photoelectricity receiver modules 5 join end to end and form, linear foot 2 is that four photoelectricity receiver modules 6 join end to end and form, and microprocessor 3 all is connected with power lead by the serial communication line with the photoelectricity receiver module 5 and the digital display screen 4 of crossfoot 1 and linear foot 2 respectively.Digital display screen 4 is the LED charactron, and microprocessor 3 relies on the direct-current switch power supply power supply.Photoelectricity receiver module 5 and photoelectricity receiver module 6 are fixed on the opaque cover plate 17, and corresponding phototriode 7 positions are drilled with aperture on the cover plate 17, use for entering light.
1) sees Fig. 2, Fig. 3, Fig. 4, each photoelectricity receiver module 5 and photoelectricity receiver module 6 respectively comprise 8 phototriodes 7 and a cpu chip 8, cpu chip 8 is formed receiving loop with 8 phototriodes 7 respectively, after phototriode 7 tops are blocked, cpu chip 8 respective pin receive a high level, the number of pin of programmed counting high level.The equidistant phototriode 7 of 5mm is installed in the front of circuit board, i.e. T0～T7, and cpu chip 8 is installed on the reverse side of circuit board.The photoelectricity receiver module adopts modular design, the one end be provided with power pins 9, communication pin 10, communication pin 11, wire pin 12, the other end be provided with power pins 13, communication pin 14, communication pin 15, wire pin 16, connecting from beginning to end during combination connects by serial communication line and power lead correspondence, can expand the length that needs arbitrarily.
See Fig. 1, the operating process of the utility model measuring method is: open microprocessor 3 power switches earlier, at this moment digital display screen 4 shows to be " 0 " entirely, measured object 18 is placed on the cover plate 17, irregular measured object is slipped over along T shape photoelectric measuring device surface, its width dimensions is read by crossfoot 1, length dimension is read by linear foot 2, microprocessor calculates and the accumulative total unit area, finishes the measurement of this irregular area, and its operation steps is as follows:
1) measured object 18 is begun to keep measured object and chi face to fit along the pulling of linear foot 2 directions from dip stick crossfoot 1 direction as far as possible;
2) when measured object covers linear foot 2 first phototriodes, microprocessor reads on the crossfoot 1 by shading electricity triode quantity 8, its width dimensions is 8 * 5mm, the phototriode distance values is 5mm on the crossfoot, the phototriode distance values also is 5mm on the linear foot, and tested region area is S1=8 * 5 * 5=200mm
