Description

Technical Field

[0001] The invention belongs to the technical field of underwater acoustic equipment signal measurement, and in particular relates to an underwater acoustic equipment continuous operation detection and alarm device. Background Art

[0002] With the continuous development and improvement of hydroacoustic technology over the past decade, the output of various types of hydroacoustic equipment independently developed by my country has been increasing, and the amount of measured data has also gradually increased. The traditional continuous operation detection method is that multiple staff members periodically measure each output channel of the equipment in turn, and compare the data with the standard data after obtaining it. If the data error is within 10%, it is considered to be within the normal range and can continue to operate continuously. Otherwise, it needs to be repaired and re-conducted for continuous operation detection. Due to the limitation of manpower, there is no way to observe the deviation of the equipment data in a timely manner at the first time, and the best time to lift the alarm may be missed. Summary of the invention

[0003] The purpose of the present invention is to provide an underwater acoustic equipment continuous operation detection alarm device, which uses an alarm measurement device made of a PLC system to automate the cyclic reciprocating measurement work, and uses an LM139 comparator to compare the output values ​​of the four channels of such equipment. If a deviation of more than ±10% occurs, an alarm will be issued for one of the channels of the equipment, and the PLC will be stopped from continuing to operate until the staff replaces the equipment and contacts the alarm, and then continues to operate.

[0004] In order to solve the above technical problems, the present invention provides a continuous operation detection and alarm device for hydroacoustic equipment, comprising:

[0005] Horizontal reciprocating module;

[0006] The extending and retracting module is provided at the transmission end of the horizontal reciprocating moving module, and the transmission end of the extending and retracting module is provided with a detection device tooling, and the detection is realized by controlling the extending action of several detection probes of the detection device tooling to achieve one-to-one docking with several output channels of the device to be measured;

[0007] A comparator is installed on the detection device tooling. The detection device tooling reads the data of the output channel and analyzes it, and then sends the output value to the comparator. The comparator is used to compare the output values ​​of several output channels with normal data one by one. If the comparison result deviates by more than ±10%, an alarm is issued for one of the output channels of the device to be measured.

[0008] Preferably, the horizontal reciprocating module includes: a horizontal motor, a driving wheel, a driven wheel and a conveyor belt; the horizontal motor is installed on a frame, the driving wheel is provided at the output end of the horizontal motor, the conveyor belt is respectively wound around the driving wheel and the driven wheel, the driven wheel and the driving wheel are linearly arranged, and the driven wheel is rotatably installed on the frame.

[0009] Preferably, the extending and retracting module includes an extending and retracting motor; the extending and retracting motor is locked and installed on the upper side belt of the conveyor belt.

[0010] Preferably, the number of the device to be measured, the number of the plurality of output channels and the number of detection probes are all set to four.

[0011] Preferably, the comparator adopts a LM139 comparator with four-way comparison operational amplifier.

[0012] Preferably, it also includes four alarm indicator lights, which are used to be connected to the comparator.

[0013] The present invention also provides a PLC control method for a continuous operation detection and alarm device for an underwater acoustic device, using the above-mentioned continuous operation detection and alarm device for an underwater acoustic device, comprising:

[0014] PLC-controlled reciprocating measurement operation principle;

[0015] Press the start button, the horizontal motor starts and moves from the starting position of the device to the initial position of the device, and the motor extends and retracts to extend the four detection probes on the detection device tooling, and starts to measure the four output channels of the first device to be measured simultaneously. The measurement time is controlled by the delay relay T0, and the effective data measured on the detection device tooling is compared with the normal data through the LM139 comparator; after completion, the device continues to move 20cm to reach the second device to be measured, and repeats the above actions; after running to C0-K3, it indicates the number of devices to be measured, that is, after completing the measurement of the four devices to be measured, the device returns to the initial position of the device, waits for 10 minutes, and repeats the whole process; when running to C1-K143, it indicates the end of the total number of operations, that is, the continuous operation of 24h ends, and the continuous operation of the equipment is completed;

[0016] The operating principle of the single alarm process controlled by PLC;

[0017] The valid data measured on the detection device tooling is compared with the normal data through the LM139 comparator. As long as there is an error, the entire PLC program will be paused, and the recovery button needs to be pressed manually before the PLC program can continue to start. The program will be stopped after one cycle, and the equipment will be repaired or replaced for continuous operation experiments. If a new device is replaced, it is necessary to pay attention to the reading of C1-K143, i.e. the total number of operations, and record it. The device needs to perform a continuous operation experiment again.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] After the present invention uses the detection alarm device, it is only necessary to press the start button to directly start simultaneous monitoring and sequential monitoring of the four output channels of the existing four devices. The detection device will compare the data of the four channels with the normal data through the LM139 comparator chip. If a deviation of more than ±10% occurs, an alarm will be issued for one of the channels of the device, and the PLC will be stopped from continuing to operate until the staff replaces the device and contacts the alarm before continuing the operation.

[0020] Moreover, the PLC program presented in the present invention is when the device has 4 channels and 4 devices are simultaneously performing continuous operation detection operations. If the number of channels and the number of devices that are simultaneously continuously operated need to be increased, the number of channels can be increased or decreased by simply increasing or decreasing the number of LM139 comparators and changing the number of alarm lights in the PLC. Increasing or decreasing the number of counts (C0) required for reciprocating in the reciprocating measurement PLC can increase or decrease the number of devices that need to simultaneously perform continuous operation detection operations.
