Abstract
The utility model discloses an ultrasonic receiving circuit for moving a region robot which comprises a body of an ultrasonic receiving circuit, and an input end of the body of the ultrasonic receiving circuit is further connected with a Schmitt trigger and a photoelectric coupler in series in turn. The ultrasonic receiving circuit for moving the region robot of the utility model is suitable for movable location of region robots, can prevent wireless signals and ultrasonic signals from generating interference mutually, and has rectification function and simple structure.
Description
Technical field
The utility model relates to a kind of ultrasound wave receiving circuit, relates in particular to a kind of ultrasound wave receiving circuit that is used for regional robot movement.
Background technology
Along with the unify fast development of Robotics of global positioning system, people have reached the unprecedented degree of depth and range for multi-functional and requirement hi-Fix, its way of realization is also abundant further, people can pass through onboard navigation system, portable navigation system etc., realize the control for self-position.But also multiple technologies in the application of different field new thinking have been proposed: at first be that for example people wish in indoor realization positioning functions such as warehouse, halls for high-precision positioning requirements among a small circle thereupon.Next is for the replenishing of gps system, and for example realizes locating or the like in the zone that satellite-signals such as tunnel can't arrive.Moreover people wish that robot can help the mankind to finish more more important work, has proposed robot positioning system's relevant issues and solution thus.For the positioning function that solves regional area and high security of system degree, can adopt ultrasonic technology and wireless technology to realize accurate location, therefore need to adopt the ultrasound wave receiving circuit, and applicant of the present utility model is devoted to study a kind of ultrasound wave receiving circuit that is applicable to regional robot movement.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art and a kind of ultrasound wave receiving circuit that is used for regional robot movement is provided, be applicable to the running fix of regional robot, can avoid wireless signal and ultrasonic signal to produce interference mutually, and have rectification function, simple in structure.
The technical scheme that realizes above-mentioned purpose is: a kind of ultrasound wave receiving circuit that is used for regional robot movement, comprise ultrasound wave receiving circuit body, wherein, the output terminal of described ultrasound wave receiving circuit body also is in series with a Schmidt trigger and a photoelectrical coupler successively.
The above-mentioned ultrasound wave receiving circuit that is used for regional robot movement, wherein, described Schmidt trigger adopts 8 pin time-base integrated circuit NE555.
The above-mentioned ultrasound wave receiving circuit that is used for regional robot movement, wherein, the pin 4 of described 8 pin time-base integrated circuit NE555 meets voltage VCC with pin 8.
The above-mentioned ultrasound wave receiving circuit that is used for regional robot movement, wherein, first three level of described ultrasound wave receiving circuit body is an amplifier circuit, back one-level is a voltage follower circuit.
The beneficial effects of the utility model are: the utility model adopts Schmidt trigger NE555, make asserts signal RESET be in noble potential always, when the input signal sine wave greater than 1/3VCC, promptly during the 1.6V left and right sides, jump ripple in the generation, thereby realize schmidt trigger function; Adopt photoelectrical coupler, can avoid wireless and produce the situation of interference mutually with ultrasound wave; When ultrasound wave was propagated in air, the decay of its energy was directly proportional with distance, and promptly the near more signal of distance is strong more, and distance signal far away more is weak more, because the scope of input signal is bigger, necessarily required the amplifying circuit gain amplifier to want big, the needs when adapting to small-signal; Gain amplifier is wanted and can be changed, with the big needs of adaptation signal variation range.Therefore first three level of the present utility model is an amplifier circuit, back one-level voltage follower circuit.
Description of drawings
Fig. 1 is the circuit diagram that is used for the ultrasound wave receiving circuit of regional robot movement of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1, there is shown a kind of ultrasound wave receiving circuit that is used for regional robot movement of the present utility model, comprise ultrasound wave receiving circuit body 1, the output terminal of this ultrasound wave receiving circuit body 1 also is in series with a Schmidt trigger 2 and a photoelectrical coupler 3 successively.
In the utility model, Schmidt trigger 2 adopts 8 pin time-base integrated circuit NE555, its pin 4 meets voltage VCC with pin 8, asserts signal RESET is in noble potential always, when the input signal sine wave greater than 1/3VCC, when being the 1.6V left and right sides, jump ripple in the generation, thereby realize schmidt trigger function.
It is 6N135 that photoelectrical coupler 3 adopts model, and purpose is that ultrasonic signal and the wireless signal when avoiding regional robot movement location produces interference mutually.
In the present embodiment, first three level of ultrasound wave receiving circuit body 1 is an amplifier circuit, and back one-level is a voltage follower circuit.When ultrasound wave was propagated in air, the decay of its energy was directly proportional with distance, and promptly the near more signal of distance is strong more, and distance signal far away more is weak more, because the scope of input signal is bigger, necessarily required the amplifying circuit gain amplifier to want big, the needs when adapting to small-signal; Gain amplifier is wanted and can be changed, with the big needs of adaptation signal variation range.Therefore adopt this first three level of the utility model to be amplifier circuit, the scheme of back one-level voltage follower circuit can satisfy the situation of distance far the time.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection domain of the present utility model.
