Embodiment
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
As shown in figs. 1-7, a kind of laser scanner proving installation and test circuit, comprise power module 8, fixture and display 9.Described fixture one end is electrically connected with described power module 8, and the described fixture other end is electrically connected with described display 9.The display 9 that the present embodiment adopts is liquid crystal display, improves display quality.Described fixture comprises upper cover body 4 and lower cover 6, and both connections fixed by snap, are convenient to the dismounting of fixture.The outside end face side of described lower cover 6 is provided with mounting hole, and this installing port internal fixtion is provided with CMOS 3; The outside end face opposite side of described lower cover 6 is provided with power inlet 1 and signal output 2.The signal that described signal outlet 2 exports is AV vision signal.The quantity of described mounting hole is 2, namely on this fixture, is provided with 2 CMOS 3, guarantees that the result being detected gained scanning laser cell present position by described CMOS 3 is more accurate like this.In addition, CMOS 3 also has the advantages such as cost-saving reduction power consumption.The inner side corresponding with described mounting hole of described lower cover 6 is provided with stationary platform 7, and is fixed with CMOS pcb board by screw in described stationary platform 7.Sensor devices 3 carrys out the change of perception laser scanner positions by difference laser scanner being in varying level position time institute Emission Lasers degree of strength, and by CMOS pcb board, light signal is converted to electric signal.Described lower cover 6 inside is provided with draw-in groove 5 with the described corresponding side of signal output 2, is provided with I/O port switching pcb board in described draw-in groove 5.Described CMOS pcb board and described I/O port are transferred between pcb board and are connected by circuit.The electric signal exported by CMOS pcb board transfers to again I/O port switching pcb board and is converted to AV vision signal, is connected with described LCD circuit finally by described signal output 2.Because the signal exported is AV vision signal, so be provided with 2 signal outputs 2.So just, can carry out in real time the change of laser scanner horizontal level when adjusting the horizontal level of laser scanner and detect intuitively.
