The utility model utilizes the range finding of ultrasound wave principle; Keep ultrasonic reflections echo ranging principle, integrated ultrasonic correlation range measurement principle again simultaneously, but both unit detection ranges; Also but two-shipper is mutually correlation and measures larger distance, and the utility model is measured fast, use is flexible, price is cheap.
Description of drawings
Fig. 1 is the hardware block diagram of the ultrasound wave meter ruler of the utility model.
Embodiment
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
The hardware configuration theory diagram of described ultrasound wave meter ruler is as shown in Figure 1, comprises single-chip microcomputer, temperature sensor, transceiving integrated ultrasonic sensor, ultrasonic transmit circuit, ultrasound wave receiving circuit, LCD MODULE and key-press module.Single-chip microcomputer is chosen as the STC12C5201AD chip of low price high reliability; This chip has self 10 integrated AD conversion; With the EEPROM of 1Kb, be used to write down the result of each measurement, and can set power-down mode; Utilize keyboard or ultrasound wave receiving circuit to arouse, can greatly reduce system power dissipation through interruption; Temperature sensor is that temperature sensitive resister passes through test electric bridge access Chip Microcomputer A conversion mouth; For system's range finding provides corrected parameter, transceiving integrated ultrasonic sensor is selected water proof type ultrasonic sensor TCF40-16TR1, and said ultrasonic transmit circuit is made up of triode and transformer etc.; Transformer part is adapted to battery powered low-voltage; Increase the ultrasonic emitting acoustic pressure simultaneously, increase transmitting range, the ultrasound wave receiving circuit comprises amplifier LM324, triode, diode, electric capacity and resistance; Be used for the ultrasound wave feedback signal is amplified and converted pulse signal to; Testing circuit identification altogether, LCD MODULE is meant the low-power consumption display screen that can show distance measurement mode, distance value and temperature, button comprises the distance measurement mode options button and measures key.
But this ultrasound wave meter ruler ultrasound wave is the unit detection range both, but also two-shipper is mutually correlation measurement larger distance, and present embodiment is mutually correlation to two ultrasound wave meter rulers and is elaborated, and its principle of work is following:
When two ultrasound wave meter rulers of the utility model are distributed in the diverse location of measurement, and one of them presses when measuring key, and processor starts timer immediately and picks up counting; When timing reaches regulation after the set time, launch the ultrasound wave of certain-length through ultrasonic transmit circuit, after the ultrasound wave meter ruler receiving circuit of another position receives ultrasonic signal; Start timer on one side, Yi Bian monitor the duration of this bundle ultrasonic intensity, through the judgement of processor; Transmit if measure,, just launch a branch of ultrasound wave feedback signal when timer arrives regulation during the set time; Feedback ultrasonic signal length is uneven in length with the emission ultrasonic signal, and differs greatly, and the emission ultrasonic signal is extremely short; So that last ultrasound wave meter ruler judges that this signal is that the undesired signal that Ambient is returned still is the ultrasound wave meter ruler feedback signal of another position, after last ultrasound wave meter ruler receives and is judged as feedback signal, read the timer timing value immediately; And with the timer zero clearing; Reclocking, last ultrasound wave meter ruler processor need be when stipulated time next time no shows, accomplish data processing and show.When timer arrives rule after the time once more; This meter ruler a branch of ultrasonic measuring signal of redispatching down, and the ultrasound wave meter ruler of another position receive once more send signal after, also be to read the timer timing value immediately simultaneously; And with the timer zero clearing; Reclocking, during the stipulated time, processor was accomplished data processing and was shown in the timer no show while.It also after arriving the stipulated time, sends the ultrasound wave feedback signal once more, so back and forth carries out, and is disconnected up to measuring key.If behind the last position ultrasound wave meter ruler emission measurement signal 1s, still fail to receive the feedback measuring-signal, then processor thinks that this measuring-signal loses; From next bundle measuring-signal of new transmission, because two ultrasound wave meter rulers are identical product, the set time that the regulation emission is waited for equates; And should the set time greater than the duration of ultrasound wave hangover repercussions; So can calculate tested distance at 2,, be left intact if the signal that last position ultrasound wave meter ruler receives is a undesired signal.Timed sending time is long, is disturbed by the signal of surrounding environment reflected back to get rid of ultrasound wave.
