[0021] Specifically, as Figure 2 shown in the figure, the fish slaughtering production line 5 includes an upper conveying mechanism 51 and a lower conveying mechanism 52 that are staggered up and down and connected end to end. The upper conveying mechanism 51 includes an upper conveying belt 511, an upper driving roller 512, an upper driven roller 513, and an upper reduction gear motor 514.

[0023] The detection and alarm device is used to detect faults and give alarms for the above-mentioned fish processing equipment, and includes a detection device 20 and a control and adjustment device 30. The fish processing equipment that needs fault detection and maintenance can be one or more of a hoist 1, a back-opening machine 4, a fish slaughtering production line 5, a slicing machine 6, a belt conveyor 7, a bubble cleaning machine 8, a vibrating drainer 9, a feeding machine 10, a tumbler 11, and a quick-freezing machine 14. Motors for driving their operations are installed inside these fish processing equipment. In this embodiment, the working principle of the above-mentioned detection and alarm device is illustrated by taking the fish slaughtering production line 5 as an example.

[0024] The detection device 20 includes a speed sensor 22, a speed measurement sensor 23, a torque sensor 24, a temperature sensor 25, and a vibration sensor 26. These detection components can collect detection signals reflecting the operating state of the fish processing equipment in real time, such as bearing temperature, motor vibration, shaft rotation speed, belt rotation speed, and motor torque.

[0025] As Figure 2 shown, the speed sensor 22 is installed on the bearing seat 516 and is used to detect the shaft rotation speed in real time. When there is a situation of belt slipping in the fish slaughtering production line 5, the speed sensor 22 feeds back the signal to the PLC controller 31, and alarms and stops the machine in time for timely maintenance; the speed measurement sensor 23 is used to detect the rotation speed of the motor in real time, the torque sensor 24 is used to detect the torque of the motor, and the temperature sensor 25 is used to detect the bearing temperature in real time. When the bearing temperature is too high, the PLC controller 31 will collect key parameter information and alarm and stop the machine in time for timely maintenance; the vibration sensor 26 is used to detect the vibration of the motor in real time and automatically alarms and stops the machine when rotor imbalance occurs; in short, when the operating state of the fish processing equipment is abnormal, such as when the bearing temperature is too high, the motor vibration amplitude is too large, the motor torque is abnormal, the shaft rotation speed is abnormal, etc., the PLC controller 31 will collect key parameter information and alarm and stop the machine in time for timely maintenance.

[0026] The control and adjustment device 30 includes a PLC controller 31, a touch screen 32, a PID regulator 33, a frequency converter 34, an I / 0 communication interface 35, and an alarm 36. The PLC controller 31 is communicatively connected to the I / 0 communication interface 35 and communicatively connected to each detection component through the I / 0 communication interface 35. The PLC controller 31 receives the detection signals reflecting the operating state information of each fish processing equipment collected by each detection component of the detection device 20, and each detection component sends the detection signals to the PLC controller 31 through the I / 0 communication interface 35.

[0027] The alarm 36 is communicatively connected to the PLC controller 31. When the working state of a certain component of the fish processing equipment is abnormal or needs maintenance, the PLC controller 31 controls the alarm 36 to give an alarm for equipment maintenance.

[0028] The storage unit in the PLC controller 31 is configured with the initial state of the fish processing equipment and the alarm threshold parameters. The alarm threshold parameters include the threshold parameters for various equipment state parameters to reach the alarm level, such as the threshold parameters for the bearing temperature, shaft speed, belt speed, vibration amplitude, etc. to reach the alarm level. If a certain parameter during operation reaches the set threshold, the alarm 36 is controlled to alarm and stop the machine according to the corresponding setting.

[0029] As Figure 3 As shown, the PID regulator 33 is communicatively connected to the PLC controller 31 and the frequency converter 34, and is used to receive the control signal from the PLC controller 31 and send the PID control signal to the frequency converter 34, so as to control the operating state of the motor; the input end of the frequency converter 34 is communicatively connected to the PID regulator 33, and the output end of the frequency converter 34 is connected to the motor of the fish processing equipment. The frequency converter 34 controls the speed of the motor in the fish processing equipment, that is, the frequency converter 34 receives the PID control signal sent by the PID regulator 33 to complete the control of the motor.

[0030] The touch screen 32 is communicatively connected to the PLC controller 31. The touch screen 32 is used to monitor the operating state of each fish processing equipment and display the fault information. The touch screen 32 displays the data information collected by each detection component and the frequency of the frequency converter 34 in real time. For example, when the touch screen 32 monitors that the motor speed detected by the speed measuring sensor 23 is abnormal, the PLC controller 31 issues a control instruction to automatically adjust and control the speed of the motor through the PID regulator 33 and the frequency converter 34 in sequence.

[0031] As Figure 8 As shown, the present invention also provides a fish deep processing technology using the above-mentioned complete set of fish deep processing equipment, including: the elevator 1 lifts and transports the fish in the fish pond to the workbench 2, the grading scale 3 on the workbench 2 weighs and grades the fish, the back-opening machine 4 performs back-opening treatment on the fish, the fish killing production line 5 transports the fish that has been descaled, had its belly cut open, and had its internal organs removed to the slicing machine 6, the slicing machine 6 slices the fish meat, the belt conveyor 7 transports the sliced fish meat to the bubble cleaning machine 8, the bubble cleaning machine 8 cleans the sliced fish meat, the vibrating drainer 9 performs vibrating dehydration operation on the sliced fish meat, the feeding machine 10 feeds the tumbling machine 11, the tumbling machine 11 performs tumbling processing on the fish meat, the vacuum packaging machine 12 performs vacuum packaging on the fish meat, the metal detector 13 detects metals in the fish meat, and the quick-freezing machine 14 performs freezing treatment on the packaged fish meat; during the operation of each fish processing equipment, the detection and alarm equipment detects faults of the above-mentioned fish processing equipment for timely maintenance.
