Second embodiment
This ranging system is broadly divided into three parts: ultrasonic transceiver module, multistage amplification sampling module, main control chip
500。
Ultrasonic transceiver module, by main control chip 500 by coming different pin enabled height to controlling different passage
Send the break-make of probe and power supply thus be transmitted the selection of passage.While chip enables pin, chip is also to decoding
The data just received different passages that enable of device pin are incorporated in follow-up multistage amplifier circuit 300.Further, this
Transmitting-receiving probe can freely form a little module, for the interference avoiding noise to bring, needs directly to connect one after receiving terminal
Waveform is amplified by amplifying circuit 300, the amplifying circuit 300 of 50 times of this utility model employing.Owing to can freely arrange
In any position of mobile robot, there is the advantage that motility height volume is little.
At multistage amplifier circuit 300, can need to select the number of stages of amplification of correspondence according to actual range, the present embodiment is adopted
Be three grades amplify patterns as it is shown on figure 3, detection range from 1cm to 2m about detection range.Due to sound wave return
Energy and distance are relevant, apart from the nearest barrier according to bigger amplification, Wave data can be caused to reach threshold value V
Straight line, and away from too far away, by less amplification, Wave data is difficult to effectively distinguish with noise, therefore this reality
By a kind of scheme using different amplification according to the time of novel employing.In this utility model, use 8 times every grade
Amplification.
As in figure 2 it is shown, i.e. after multistage amplifier circuit 300 receives the data that transceiver module is sent, amplify through one-level
After, one circuit of data that one-level is amplified is sent to main control chip 500 through plastic filter circuit 400 and reads AD, another
Circuit carries out follow-up amplification.Two grades of follow-up three grades of amplifications and so on.After shaping filter, AD value is in the half of threshold value
Fluctuate up and down, i.e. V1.Within the T1 time, i.e. read the AD value that one-level is amplified, within the T2-T1 time, read two grades of AD values amplified,
Three grades of AD values amplified are read within the T3-T2 time.Wherein, AD value, T1, T2, T3 equivalence need to be according to applied environment sets itself
Numerical values recited.
Because the size of the distance of distance and reflecting surface affects the size of waveform, when this utility model uses foundation
Between scope obtain the AD value of corresponding amplification.One-level is amplified in the value T1 time, and two grades are amplified value T2 time, successively class
Pushing away, N level amplifies value Tn.
The data received are carried out crest seeking by main control chip 500 constantly, for avoiding multiple barriers on same straight line
Interference, value takes the value of first crest in the time period.And obstacle can be calculated according to the size of crest in the time period
The size of thing reflecting surface, this is not set forth in detail by this utility model.Amplify, when the first order, the Wave data come and do not find ripple
Peak, then process the second level and amplify the data of coming, the like.Once find crest or in stipulated time Tn, do not find ripple
Peak, then selected next passage by main control chip 500.
After often completing a poll, communication module the data obtained sent or be shown to display screen.This
Utility model is due to needs polylith detection circuit plate, in order to ensure mutual communication, therefore uses CAN (controller local area network
Controller Area Network, abbreviation) communication modes.
As it is shown in figure 5, this utility model additionally provides a kind of detection method:
A kind of multi-channel serial ultrasonic distance-measuring method, comprises the following steps:
S20: ultrasonic transceiver module sends ultrasound wave, then reclaims described ultrasound wave；
S30: the waveform of the described ultrasound wave received is amplified
S40: the waveform shaped circuit shaping of the described ultrasound wave after amplifying, is sent to main control chip 500
S50: described main control chip 500 carries out shape and/or the distance of computational analysis measurand.
Preferably, described multi-channel serial ultrasonic distance-measuring method, described S40: before perform S35: described main control chip
500 do not find crest in the waveform that single-stage amplifying unit described in the first order sends, then the described single-stage of labelling this grade is amplified single
The waveform of unit is invalid, the most again performs S20 to S30, then reads described labelling, controls single-stage described in the super first order and amplifies single
The waveform that unit sends sends to single-stage amplifying unit described in the second level, and takes out described in single-stage amplifying unit described in the second level
Waveform.
Preferably, described multi-channel serial ultrasonic distance-measuring method, described S35: mark whether to exceed default described in judgement
Value；If not less than, then in the described single-stage amplifying unit of 1 order of magnitude bigger than mark value, take out described waveform；If it is super
Cross, then switch another described ultrasonic transceiver module.
