Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
Principle of work of the present utility model is as follows:
Ultrasonic ranging sensor 4 is equipped with a ultrasonic transmitter and a ultrasonic receiver, during instrumentation ultrasonic transmitter by fixing rule with these ultrasonic signals through constantly launching ultrasonic signal behind specific codings to concrete surface, when ultrasound wave feeds back from concrete surface, signal is received device and accepts, by digital amplifying circuit 5 and A/D conversion, after according to the mistiming of launch time and acceptance it being decoded then, signal is delivered to central processing unit 8 to be calculated, relatively, analyze, according to program setting, the display of constantly target range information being seen off shows that status signal is sent to the LED indication.Alerting signal is sent to alarm equipment alarm, and constantly with these alerting signal stored records, goes round and begins again.
Signal input circuit: it is by ultrasonic sensor 4, digital amplifier 5, the A/D change-over circuit, clock circuit 6, the compositions such as switch 7 circuit of closing a position, the radiated element of ultrasonic sensor 4 is constantly launched ultrasound wave to concrete surface with the audio frequency of 115dB during circuit working, the receiving element of ultrasonic sensor is also constantly receiving the ultrasonic signal that reflects from concrete surface simultaneously, after modulation circuit on the sensor transmits and receives generation according to ultrasonic signal mistiming gives the instrumentation tap circuit with its electric current that is modulated into 4-20mA, instrument enters A/D change-over circuit TLC1543 through LM324 operational amplifier amplified signal and carries out the AD conversion, and the signal of sensor has become digital quantity by original analog quantity after the A/D conversion; For clock accurately is provided to instrument, selected for use clock chip DS1302 to provide clock information to central processing unit 8 here by it;
Do not influence the operation of closing a position when guaranteeing concreting, used the switch 7 of closing a position here, the switch 7 of just often closing a position is swung to the end that vibrates, and send high level signal for central processing unit 8, and switch is swung to the end of closing a position and sent low level signal for central processing unit 8 when closing a position.
Signal processing circuit: it is made up of cpu central processing unit, data-carrier store, program storage etc., and program storage is integrated in CPU inside.The signal of sensor has become digital quantity by original analog quantity after the A/D conversion, give display circuit CD M1190A with shows signal after at this moment central processing unit 8 is just constantly gathered, compares, calculates, analyzed it according to the setting of program and show; To owe to shake, cross the signal that shakes and send alarm circuit, transistor 13, hummer 12, photoelectrical coupler 16, integrated circuit 17, signal lamp, alarm lamp 14 etc. carry out display alarm; To owe to shake, cross the signal that shakes simultaneously and send storer 9 to store, go round and begin again.
The data-carrier store 9 here adopts two 24C256 to use, and every be the 32K byte, and two is the 64K byte, can store owe to shake, mistake shakes surplus the information 10000.
The vibrating time that a science is all arranged for the concrete of each grating in the concrete that guarantees each label, here used the method for tabling look-up, i.e. 16 grating schemes of the concrete of 4 labels, corresponding have 16 kinds to vibrate the control time, this control time can be provided with according to the empirical parameter at scene, and vibrating for concrete science provides means.
