Abstract
The invention relates to a detection device and particularly relates to a handheld type wireless receiver for determining a target position. The handheld type wireless receiver at least comprises a handheld type wireless receiver (1) and a target body (2) with a directional antenna and a control circuit (3), wherein the directional antenna is coupled with a motor (303) shaft and the motor shaft rotates to drive the directional antenna to rotate around the shaft; the control circuit is used for obtaining a rotating angle of the motor shaft and processing and calculating the rotating angle to obtain a current azimuth angle; radio waves with the azimuth angle are sent by the directional antenna; and when the handheld type wireless receiver (1) receives the radio waves with the azimuth angle, which are sent by the directional antenna, the azimuth angle is displayed on a display. According to the handheld type wireless receiver for determining the target position, the forward rotation azimuth information of the directional antenna is sent out through the directional antenna; and after the handheld type wireless receiver receives the forward rotation azimuth information of the directional antenna, the information is displayed by the display, so that the handheld type wireless receiver can determine the position of the target body by handholding.
Description
Technical field
The present invention relates to a kind of pick-up unit, the portable wireless receiver determined of a kind of target azimuth particularly is used for seeking the orientation of target.
Background technology
In many cases, need to seek target, as in the parking lot, park cars too much, when returning rear searching, really can't determine the position of storing cycle.Run because of carelessness mistake such as pet, do not know to run to which direction.
Vision can be identified rapidly the object that differentiation is arranged of observing, and can not identify rapidly the object without distinguishing of observing, and the parking lot is not when having obvious reference substance, and it is frequent that above-mentioned situation occurs.
Summary of the invention
The purpose of this invention is to provide the portable wireless receiver that a kind of target azimuth is determined, can promptly seek the orientation of target.
The object of the present invention is achieved like this, the portable wireless receiver that a kind of target azimuth is determined, it is characterized in that: comprising: single-chip microcomputer, wireless receiving module, display, battery and dc/dc change-over circuit, battery is the 7-5 battery, battery by the dc/dc change-over circuit with the 1.2-1.5v voltage transitions become 3 or 3.3v or 5v voltage supply with display, wireless receiving module and single-chip microcomputer, single-chip microcomputer is electrically connected with wireless receiving module and display by the I/O mouth, single-chip microcomputer receives the wireless digital content of wireless receiving module by the I/O mouth, the antenna of wireless receiving module adopts screw thread antenna or wire antenna, and it can comprehensive reception information.
Advantage of the present invention is: the azimuth information of directional antenna forward rotation is sent by directional antenna, after the portable wireless receiver receives the azimuth information of directional antenna forward rotation, show by display, hand-held portable wireless receiver just can be determined the orientation of objective body.
Description of drawings
The invention will be further described below in conjunction with the embodiment accompanying drawing:
Fig. 1 is embodiment of the invention schematic diagram;
Fig. 2 is directional antenna by the synoptic diagram that is of coupled connections with motor shaft;
Fig. 3 is photoelectricity take-up reel 3 structural representations;
Fig. 4 is portable wireless acceptor circuit schematic diagram.
Among the figure, 1, the portable wireless receiver; 2, objective body; 3, directional antenna and control circuit.
Embodiment
As shown in Figure 1, the portable wireless receiver that a kind of target azimuth is determined, at least comprise a portable wireless receiver 1, the objective body 2 that directional antenna and control circuit 3 are arranged, directional antenna is by being of coupled connections with motor 303 axles, and motor shaft rotates the drive directional antenna and sways, and control circuit obtains the motor shaft angle of rotation and angle of rotation is processed calculating, obtain working as forward angle, send by directional antenna and be loaded with azimuthal radiowave; When portable wireless receiver 1 receive directional antenna send be loaded with azimuthal radiowave after, the display orientation angle is on display.
Fig. 2, shown in Figure 3, the synoptic diagram that is directional antenna by being of coupled connections with motor shaft, the axle 307 of motor 303 is fixed with scrambler 305 and cover has photoelectricity take-up reel 304, scrambler 305 is magnetic or light coding, when control circuit 301 passes through driving circuit 302 drive motor 303, when the axle 307 of motor 303 rotates, drive scrambler 305 and rotate, photoelectricity take-up reel 304 is not rotated.
By the angular displacement of scrambler 305 to the shaft rotation, be fixed with photoelectricity take-up reel 304 with axle is coaxial, photoelectricity take-up reel 304 is disc structure, compass 3042 is coaxial in photoelectricity take-up reel 304, photoelectricity take-up reel 304 circumferentially has photoelectric device 3041, and compass 3042 targets 2 directions change, when compass 3042 points to photoelectric device 3041 upper end, it is influenced that the luminescent device of one side is invested the light intensity of corresponding photoelectric device, and affected photoelectric tube is for pointing to south.Angle is constant between 304 1 reference angles of photoelectricity take-up reel and directional antenna 306 fronts, directional antenna 306 rotates the angular displacement that is provided variation by scrambler 305, can simple push derive the azimuth information that directional antenna 306 rotates thus, the azimuth information of directional antenna 306 forward rotation is sent by directional antenna 306, after portable wireless receiver 1 receives the azimuth information of directional antenna 306 forward rotation, show by display, hand-held portable wireless receiver 1 just can be determined the orientation of objective body 2.Among the present invention, control circuit 301 is single-chip microcomputer, and single-chip microcomputer is electrically connected with each photoelectric tube of photoelectricity take-up reel 304 by I/O, be used for reading the intensity signal of photoelectric tube, determine the position of compass by intensity signal, calculate the angle with directional antenna 306 forwards, provide azimuth information.
When motor 301 drives directional antenna 306 rotation, owing to adopt directional antenna, when therefore only having directional antenna 306 to turn to portable wireless receiver 1 position angle, portable wireless receiver 1 just can receive information, and 180 degree of the azimuth information of this moment are the real azimuth information of objective body 2 just the time in the other direction.
As shown in Figure 4, portable wireless receiver 1 comprises: single-chip microcomputer 101, wireless receiving module 102, display 106, battery 105 and dc/dc change-over circuit 104, battery is the 7-5 battery, battery 105 by dc/dc change-over circuit 104 with the 1.2-1.5v voltage transitions become 3 or 3.3v or 5v voltage supply with display 106, wireless receiving module 102 and single-chip microcomputer 101, single-chip microcomputer 101 is electrically connected with wireless receiving module 102 and display 106 by the I/O mouth, single-chip microcomputer receives the wireless digital content of wireless receiving module 102 by the I/O mouth, the antenna 103 of wireless receiving module 102 adopts screw thread antenna or wire antenna, and it can comprehensive reception information.
The parts that present embodiment is not described in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not one by one narration.
