Background technology
Ultrasonic range finder is widely used in a lot of fields at present, for example engineering range finding, and radar for backing car etc., but a lot of stadimeter all can only demonstrate measurement result, uses not to be very convenient.The present invention proposes a kind of features simple structure, simplicity of design, modular construction, can be accurately, convenient, range measurement system that safety is surveyed, and the employing voice broadcasting system makes it measurement data in time can be reported, so that the gauger obtains data more intuitively.Native system is subjected to external interference less, the integrated level height, and volume is little, and expense is moderate, can satisfy the requirement of a lot of different range finding occasions.
Summary of the invention
It is light and handy to the present invention proposes a kind of bodily form, is easy to carry, distance mearuring equipment reasonable in design, and it can not contact object and measures accurate distance, the result is demonstrated at LED, and by voice broadcasting system measurement result is quoted.
The technical solution adopted in the present invention is: but a kind of ultrasonic ranging system of voice broadcast it is characterized in that, be provided with: key control unit 11, voice broadcast module 12, power module 13, display module 14 and ultrasonic wave module 15.
Described key control unit 11 is used for control and coordinates each module work, is responsible for handling and calculating the data that have the ultrasound wave receiver module to record, and measurement result is sent to output module.
Described voice broadcast module 12 links to each other with main control unit 11, with the Chinese speech synthesis module the synthetic Chinese speech of measurement result is reported with loudspeaker again.
Described power module 13 to the total system power supply, comprises battery and corresponding battery protecting circuit and charging circuit.
Described display module 14 links to each other with main control unit 11, adopts charactron that measurement result is shown.
Described ultrasonic wave module 15 links to each other with main control unit 11, for generation of measuring sound wave and receiving the ultrasound wave that reflects.
But the ultrasonic ranging system of a kind of voice broadcast of the present invention, be to adopt the Chinese speech synthesis system, itself and conventional ultrasonic wave stadimeter are made up, improve the convenience that measurement result is obtained, the user can be had under the inconvenient situation in vision obtain detection data easily.This range measurement system is powerful, and structural design is simplified, and it is low to consume energy, and can effectively increase work efficiency, and alleviates the hand labor of detection, satisfies in daily life and industrial range observation demand, and the market development potential is huge.

Embodiment
Below in conjunction with embodiment and accompanying drawing but the ultrasonic ranging system of the present invention-a kind of voice broadcast is made detailed explanation.
As shown in Figure 1, a kind of ultrasonic ranging system with voice broadcast function of the present invention includes: key control unit 11 is used for control and coordinates each module work, be responsible for handling and calculating the data that the ultrasound wave receiver module records, and measurement result is sent to output module; Ultrasonic wave module 15 can produce and measure sound wave and receive the ultrasound wave that reflects; Display module 14 adopts charactron that measurement result is shown; Voice broadcast module 12 is reported out with the synthetic Chinese speech of measurement result with the Chinese speech synthesis module; Power module 13 comprises battery and corresponding battery protecting circuit and charging circuit, and is the total system power supply.
Described key control unit 11 mainly refers to HT46RU232 type single-chip microcomputer, is used for control ultrasonic wave module 15 measurement target things and measurement result is carried out computing, the result is exported by display module 14 and voice broadcast module 12 again.
As shown in Figure 2, described voice broadcast module 12 mainly refers to SYN6288 Chinese speech synthesis chip 21 and the audio drive circuitry 22 that links to each other with it and loudspeaker 23.After the measurement result that 11 pairs of ultrasonic wave module 15 of key control unit are returned is calculated, the result is sent to voice broadcast module 12 by the asynchronous serial delivery outlet, report with the synthetic Chinese speech signal of the digital signal that receives and by loudspeaker 23.
Described power module 13 to the total system power supply, comprises the big capacity 5V lithium battery of a 1200mAh, can guarantee permanent cruising time; A battery protecting circuit prevents electric leakage and overcharges for the protection of lithium battery; The charging circuit that the mini USB interface is housed, it is very convenient to charge.
Described display module 14 mainly refers to the digital display tube of quaternity, is after key control unit 11 calculates the distance of measured object and measurement point, and the result is outputed to display module 14 by the I/O mouth, and display module 14 shows data.
As shown in Figure 1, described ultrasonic wave module 15 is by ultrasound wave transmitting probe T, ultrasound wave receiving transducer R and temperature sensor are formed, the emission trigger end of ultrasonic wave module 15 is received the square wave of launching 8 40KHz after the high trigger signal that key control unit 11 sends, and whether detection has return signal automatically, ultrasound wave receiving transducer R receives the current environmental temperature that ultrasonic wave module 15 is surveyed according to temperature sensor behind the close echo result is revised the back by high level of I/O mouth output, the time that high level continues is exactly that ultrasound wave is from being transmitted into the correction time of returning, being real time that ultrasound wave comes and goes between from the measurement point to the measured point revises time of adjustment according to current environmental temperature, utilizes this time and default velocity of propagation just can calculate measurement point to the air line distance of measured point.
This ultrasonic ranging system structural design is simplified, and it is low to consume energy, and is applicable to various rugged environments, is a kind of very practical tool in daily life and the production, has very big marketing potentiality.
