In practical situations, when the exploration equipment is buried in the earth, the exploration personnel are extremely difficult to retrieve only by eyes, which brings about great data and money loss. And when the device is buried by the soil layer, the illumination intensity received by the exploration equipment is greatly reduced, so if a photoelectric sensor is used in combination with the sound production equipment, the sound production of the sound production device can be realized when the device is buried by the soil, and the device is favorable for exploration personnel to rely on the effective recovery device of sound information.

The circuit structure is as shown in fig. 3, the left sensor is a photoelectric sensing module, the middle AT89c52RC is a programmable main control program chip of a control circuit module, the upper regulator on the right side is a voltage stabilizing module, the Passive buzzers 1 and 2 are respectively a first Passive buzzer and a second Passive buzzer, and the Active buzzers 1 and 2 are respectively a first Active buzzer and a second Active buzzer. The grounding end of each module is grounded. The input end of the voltage stabilizing module is connected with a voltage source, the output end of the voltage stabilizing module is electrically connected with the voltage input ends of the control module, the sound generating module and the photoelectric sensing module respectively, the output end of the photoelectric sensing module is electrically connected with the input end of the main control program chip, and the output end of the control circuit module is electrically connected with the input end of the sound generating module.
The voltage source was a 7.4v battery. The voltage stabilizing module adopts a three-terminal voltage stabilizing integrated circuit 5, namely LM 7805. The control circuit module adopts a singlechip 4 with the model of AT89C52 RC. The sounding module comprises a first passive buzzer 2, a second passive buzzer 3, a first active buzzer 6 and a second active buzzer 7. Active buzzer only needs control module rather than electrical connection's pin output high level can realize the sound production, and to passive buzzer, when rather than electrical connection's pin output PWM ripples hour according to the duty cycle of output waveform different, the tone height that passive buzzer sent also can be different. The circuit board is a glass fiber epoxy board 8, the thickness is 1.5mm, the pitch of holes is 2.54mm, and the aperture is 1.5 mm. The P0^0, P0^1, P0^2 and P0^3 ports of the single chip microcomputer are used as I/O ports and are respectively connected with the first passive buzzer, the second passive buzzer, the first active buzzer and the second active buzzer, and the P3^2 port is used as an I/O port and is connected with the photoelectric sensor.
In this example, the programming principle and algorithm of the main control chip are as follows, the compiling environment of the main control chip is Keil5, the programming language is C, and the program burning process from the computer upper computer to the main control chip is realized through the stc burning software.
The P0^0, P0^1, P0^2, P0^3 and P3^2 ports used in the present example are initially stated, and 5 ports are defined as I/O ports, (i.e., input detection and waveform output operation can be performed through the ports). And initially setting the main control chip singlechip to regard more than 1.9v as high level and regard less than 0.9v as low level. The initial setting flag is 0, which can be regarded as the master chip being in 0 state, and all the P0^0, P0^1, P0^2 and P0^3 ports are set to low level. In this state, the main control chip executes a judgment operation to judge the input level of the port P3^2 electrically connected with the photoelectric sensor, if the input level is judged to be false (namely the input level is low level at the moment), after 10ms, the input level judgment of the port P3^2 is carried out again, and the process is continued until the input level is detected to be high level (namely the input level is judged to be true). After 5ms, the P3^2 port is judged again (to prevent the error caused by the error of the instantaneous system noise from causing the wrong judgment, so the time delay secondary judgment is carried out), if the judgment result is still true at this time, the position is marked as 1, and the master control chip is regarded as being in the 1 state. If the judgment result is false, the existence of system noise is proved to cause wrong judgment, the main control chip is still in a state of 0, and the judgment and detection operation is continued every 10 ms. And when the main control chip is in the 1 state, outputting and judging. And then, carrying out the operation of inverting the output level of P0^0 and P0^1 every 50ms, and driving the first passive buzzer and the second passive buzzer to sound by using the PWM wave with the output duty ratio of 50%. When the master control chip is in the state 1, P0^2 and P0^3 continuously output high level to drive the first active buzzer and the second active buzzer to sound. Meanwhile, the master control chip still judges the input level of P3^2 every 10ms, if the judgment result is true (namely the input level is high level at the moment), the master control chip keeps the 1 state and continuously outputs, if the judgment result is false (namely the input level is low level at the moment), secondary detection is carried out after 5ms, if the judgment result is false at the moment, the position is marked by 0, the master control chip is converted into the 0 state, the output is stopped, and all the ports P0^0, P0^1, P0^2 and P0^3 are low level. If the secondary detection judgment result is true, the main control chip still keeps the 1 state, continues the output operation and performs the judgment detection operation every 10 ms.
In the algorithm, the continuous conversion between the 0 state and the 1 state of the main control chip is realized through the level detection of the ports, the main control chip executes different operations under the 0 state and the 1 state, the P0^0, P0^1, P0^2 and P0^3 ports are all set to be low levels under the 0 state, the port level detection is carried out every 10ms, the output is realized by the P0^0, P0^1, P0^2 and P0^3 ports under the 1 state, and meanwhile, the port level detection is still kept every 10 ms. When the serial port P3^2 of master control chip and photoelectric sensor electric connection detects the photoelectric sensor and outputs high level, according to the program of recording in advance in the singlechip, the singlechip will be at P0^0, P0^1 mouth output and set up good PWM ripples, makes passive buzzer sound according to established melody (frequency), draws the level of high P0^ 2, P0^3 mouth simultaneously, makes active buzzer sound production. And the sound of the buzzer can be further amplified through the loudspeaker.
It should be noted that the algorithm and logic are not the only implementation for implementing the functions, and any algorithm similar to the present solution or logic should be included in the scope of the present application. In addition, different manufacturers, different types of chips, different programming environments and languages may be different, the programming method may also be different, the habits of the developers on the definition of the ports may also be different from the present embodiment, but the algorithm logic and the implementation method are similar and should be included in the scope of the present application.
The light sensation-based exploration equipment recycling sounding device is controlled by a main control chip programmed according to an algorithm, and the use and working processes are as follows:
and adjusting a potentiometer of the photoelectric sensor to enable the illumination threshold value to be matched with the threshold voltage of the pin of the single chip microcomputer, namely when the ambient illumination intensity is higher than the illumination threshold value, the photoelectric sensor outputs the voltage of the pin of the single chip microcomputer shown as low level, and when the ambient illumination intensity is lower than the illumination threshold value, the photoelectric sensor outputs the voltage of the pin of the single chip microcomputer shown as high level. Then the light sensation-based exploration equipment recovery sounding device is installed on exploration equipment (or the equipment installation can be carried out first, and the initial adjustment operation of the equipment is carried out). In the initial state, the 7.4v voltage source outputs stable 5v voltage through the voltage stabilizing module to supply power to other modules, and the I/O port of the single chip microcomputer outputs low level at the moment. The single chip microcomputer sets the threshold voltage of the pin through programming, and when the voltage received by the pin is larger than the set voltage, the single chip microcomputer considers that a high level is received.
When the exploration equipment is covered or buried by a map and cannot be searched by naked eyes, when the illumination intensity received by the photoelectric sensing module is lower than an illumination threshold value, the current flowing through the photoresistor is subjected to a series of rectification and amplification and then is compared with the threshold value of the comparator in the comparator, the current is lower than the threshold value of the comparator, and the output pin of the photoelectric sensing module can output a relatively high level. When the pin P3^2 of the singlechip electrically connected with the photoelectric sensing module receives the level output by the photoelectric sensing module, the pin is compared with the threshold voltage of the pin, the received power is judged to be high level, and the active buzzer and the passive buzzer sound. And the worker calculates the direction of the equipment according to the sound, so that the equipment is successfully recovered.
When the device is re-exposed to normal light, i.e. when the device is recovered, the intensity of the light received by the photosensor is higher than the light threshold, and a relatively low level is output. When the pin P3^2 of the singlechip electrically connected with the photoelectric sensing module receives the level output by the photoelectric sensing module, the pin is compared with the threshold voltage of the pin, and the received power is judged to be low level. According to the program burnt in advance in the single chip microcomputer, the single chip microcomputer pulls down the level of the ports P0^0, P0^1, P0^2 and P0^3 (the pull-down level is the low level output by the port, and the pull-up level is the high level output by the port in the same way), and the low level is output by the serial ports, and all buzzers stop sounding at the moment.
In this embodiment, the sound generation amount can be adjusted by the current amount in the circuit, and the current amount is determined by the input voltage, which can be adjusted by the voltage stabilizer. In the voltage range which can be borne by the circuit, the larger the input voltage is, the larger the current is, the larger the sound is emitted, and the smaller the input voltage is, the smaller the current is, the smaller the sound is emitted.
