Technical Field

[0001] This invention relates to the field of signal switch detection technology for compression mechanisms, and in particular to a self-testing method for signal switches of compression mechanisms, an electronic device, and its storage medium. Background Technology

[0002] Currently, most compactor garbage trucks use position signal switches as reversing switches for the compaction mechanism. Due to the harsh operating conditions of the compaction mechanism, the signal switches are prone to damage from corrosion or external impacts, leading to abnormal reversing. Operators may find it difficult to detect and handle the fault in time. If the fault is not detected and handled promptly, it can cause mechanical damage, safety accidents, and endanger public safety. Summary of the Invention

[0003] This invention provides a self-testing method for the signal switch of a compression mechanism, which solves the problem that in existing garbage truck compression mechanisms, due to the harsh operating conditions of the compression mechanism, the signal switch is easily damaged by corrosion or external impact. However, there is no obvious alarm device to indicate whether the signal switch is normal, making it difficult for people to detect. Failure to address this issue in a timely manner can lead to mechanical damage, safety accidents, and affect people's safety.

[0004] In a first aspect, embodiments of the present invention provide a self-testing method for a compression mechanism signal switch, the method comprising the following steps: S101, Control the scraper to open; S102. Determine whether the first proximity switch has received the position signal I1, whether the pressure sensing device has sensed the pressure value P, and whether the waiting time T1 has reached the preset time T1'. If the first proximity switch has received the position signal I1 or the pressure relay has reached the set pressure value P or the waiting time T1 has reached the preset time T1', then proceed to step S103. S103, Control the slide plate downwards S104. Determine whether the second proximity switch has received the position signal I2, whether the pressure sensing device has sensed the pressure value P, and whether the waiting time T2 has reached the preset time T. If the second proximity switch has received the position signal I2 or the pressure relay has reached the set pressure value P or the waiting time T2 has reached the preset time T2', then proceed to step S105. S105, Control scraper closure; S106. Determine whether the third proximity switch has received the position signal I3, whether the pressure sensing device has sensed the pressure value P, and whether the waiting time T3 has reached the preset time T. If the third proximity switch has received the position signal I3 or the pressure relay has reached the set pressure value P or the waiting time T3 has reached the preset time T3', then proceed to step S105. S107, Control the skateboard to move upwards; S108. Determine whether the fourth proximity switch has received the position signal I4, whether the pressure sensing device has sensed the pressure value P, and whether the waiting time T4 has reached the preset time T. If the fourth proximity switch has received the position signal I4 or the pressure relay has reached the set pressure value P or the waiting time T4 has reached the preset time T4', then proceed to step S101. S109. After the judgment steps S101-S108 are repeated twice, determine whether the following occur consecutively: the pressure sensor detects the set pressure value P, the first proximity switch does not receive the positioning signal I1 and the waiting time T1 reaches the preset time T1', the second proximity switch does not receive the positioning signal I2 and the waiting time T2 reaches the preset time T2', the third proximity switch does not receive the positioning signal I3 and the waiting time T3 reaches the preset time T3', and the fourth proximity switch does not receive the positioning signal I4 and the waiting time T4 reaches the preset time T4'. If the pressure sensor detects the set pressure value P consecutively after the pressure sensor is repeated twice, a full box alarm will be sounded by the voice speaker. If the proximity switch does not receive the positioning signal consecutively twice and the corresponding waiting time reaches the preset time T, a proximity switch fault alarm will be sounded by the voice speaker.

[0005] Optionally, if after two cycles, the first proximity switch fails to receive the arrival signal I1 twice in a row and the waiting time T1 reaches the preset time T1', the voice speaker will issue a fault alarm for the first proximity switch. If, after two cycles, the second proximity switch fails to receive the arrival signal I2 twice in a row and the waiting time T2 reaches the preset time T2', the voice speaker will issue a fault alarm for the second proximity switch. If, after two cycles, the third proximity switch fails to receive the arrival signal I3 twice in a row and the waiting time T3 reaches the preset time T3', the voice speaker will issue a fault alarm for the third proximity switch. If, after two cycles, the fourth proximity switch fails to receive the arrival signal I4 twice consecutively and the waiting time T4 reaches the preset time T4', the voice speaker will issue a fault alarm for the fourth proximity switch.

[0006] Optionally, the pressure sensing device is a pressure relay.

[0007] Optionally, the compression mechanism includes a cylinder for controlling the opening and closing of the scraper and the sliding of the slide plate, and a hydraulic power system for providing power to the cylinder, wherein the preset time T1', T2', T3', T4'>Q / A, where Q is the flow rate of the hydraulic power system and A is the cross-sectional area of ​​the cylinder.

[0008] In a second aspect, embodiments of the present invention provide an electronic device, including: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps in the compression mechanism signal switch self-test method.

[0009] Thirdly, embodiments of the present invention provide a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps in the self-test method for the signal switch of a compression mechanism.

[0010] Compared with existing technologies, the beneficial effects of this technical solution are as follows: In this embodiment of the invention, by controlling the operation of the compression mechanism, it is determined whether the proximity switch receives a positioning signal and whether the pressure sensing device senses a preset pressure value. If the proximity switch receives a positioning signal, the pressure relay reaches the set pressure value, or the waiting time reaches the preset time, the process proceeds to the next step. After the same operation is executed twice in a loop, it is determined whether the pressure sensing device senses the set pressure value twice consecutively, while the proximity switch does not receive a positioning signal and the waiting time reaches the preset time. If the pressure sensing device senses the preset pressure value twice consecutively in two loops, a full-box alarm is triggered by a voice horn. If the proximity switch does not receive a positioning signal twice consecutively and its corresponding waiting time reaches the preset time, a proximity switch fault alarm is triggered by a voice horn. This serves as a reminder to maintain the signal detection switch and to play a timely voice reminder when the box is full, preventing overload damage to the mechanical structure.

[0014] The main solution of this application embodiment is as follows: By controlling the operation of the compression mechanism, it is determined whether the proximity switch receives a positioning signal in each operation, and whether the pressure sensing device senses the set pressure value. If the proximity switch receives a positioning signal, the pressure relay reaches the set pressure value, or the waiting time reaches a preset time, the process proceeds to the next step. After the same operation is executed twice in a loop, it is determined whether the pressure sensing device senses the set pressure value twice consecutively, while the proximity switch does not receive a positioning signal and the waiting time reaches the preset time. If the pressure sensing device senses the set pressure value twice consecutively in two loops, a full-box alarm is triggered by a voice horn. If the proximity switch does not receive a positioning signal twice consecutively and its corresponding waiting time reaches the preset time, a proximity switch fault alarm is triggered by a voice horn. This reminds people to maintain the signal detection switch and plays a timely voice reminder when the box is full to prevent overload damage to the mechanical structure.

[0015] In current technology, most garbage compactors use position signal switches as reversing switches for the compaction mechanism. Due to the harsh operating conditions of the compaction mechanism, the signal switches are prone to damage from corrosion or external impacts, leading to abnormal reversing. Operators may find it difficult to detect and handle the fault in time. If not detected and addressed promptly, it can cause mechanical damage, safety accidents, and endanger public safety.

[0016] This application provides a solution that can perform self-testing on the compression mechanism signal switch and issue an alarm, so that operators can more clearly know whether the compression mechanism signal switch is normal.

[0017] Therefore, the present invention provides a self-testing method for a compression mechanism signal switch. (Refer to...) Figures 1 to 3 In one embodiment of the present invention, the self-test method for the compression mechanism signal switch includes steps S100-S109, wherein: S101, Control the scraper to open; S102. Determine whether the first proximity switch has received the position signal I1, whether the pressure sensing device has sensed the pressure value P, and whether the waiting time T1 has reached the preset time T1'. If the first proximity switch has received the position signal I1 or the pressure relay has reached the set pressure value P or the waiting time T1 has reached the preset time T1', then proceed to step S103. S103, Control the slide plate downwards S104. Determine whether the second proximity switch has received the position signal I2, whether the pressure sensing device has sensed the pressure value P, and whether the waiting time T2 has reached the preset time T. If the second proximity switch has received the position signal I2 or the pressure relay has reached the set pressure value P or the waiting time T2 has reached the preset time T2', then proceed to step S105. S105, Control scraper closure; S106. Determine whether the third proximity switch has received the position signal I3, whether the pressure sensing device has sensed the pressure value P, and whether the waiting time T3 has reached the preset time T. If the third proximity switch has received the position signal I3 or the pressure relay has reached the set pressure value P or the waiting time T3 has reached the preset time T3', then proceed to step S105. S107, Control the skateboard to move upwards; S108. Determine whether the fourth proximity switch has received the position signal I4, whether the pressure sensing device has sensed the pressure value P, and whether the waiting time T4 has reached the preset time T. If the fourth proximity switch has received the position signal I4 or the pressure relay has reached the set pressure value P or the waiting time T4 has reached the preset time T4', then proceed to step S101. S109. After the judgment steps S101-S108 are repeated twice, determine whether the following occur consecutively: the pressure sensor detects the set pressure value P, the first proximity switch does not receive the positioning signal I1 and the waiting time T1 reaches the preset time T1', the second proximity switch does not receive the positioning signal I2 and the waiting time T2 reaches the preset time T2', the third proximity switch does not receive the positioning signal I3 and the waiting time T3 reaches the preset time T3', and the fourth proximity switch does not receive the positioning signal I4 and the waiting time T4 reaches the preset time T4'. If the pressure sensor detects the set pressure value P consecutively after the pressure sensor is repeated twice, a full box alarm will be sounded by the voice speaker. If the proximity switch does not receive the positioning signal consecutively twice and the corresponding waiting time reaches the preset time T, a proximity switch fault alarm will be sounded by the voice speaker.

[0018] In this embodiment, the actions of the compression mechanism include scraper opening, slide plate descent, scraper closing, and slide plate ascending. During scraper opening, a first proximity switch detects whether the scraper is fully open. During slide plate descent, a second proximity switch detects whether the slide plate is fully descending. During scraper closing, a third proximity switch detects whether the scraper is fully closing. During slide plate ascending, a fourth proximity switch detects whether the slide plate is fully ascending. In this embodiment, the detection of the compression mechanism's actions and the detection of the hydraulic system are independent and do not affect each other. When the compression mechanism operates, a timer begins, which is the waiting time. The timer corresponds to the timing of the compression mechanism under the corresponding action. For example, when controlling the scraper to open, a count is performed; when the first proximity switch receives the completion signal, the count stops, and the waiting time T1 is recorded. The preset time is manually preset and set by the operator. The compression mechanism includes a cylinder for controlling the scraper opening and closing and controlling the slide plate sliding, and a hydraulic power system that provides power to the cylinder. The preset time follows the rule that T>Q / A, where Q is the flow rate of the hydraulic power system and A is the cross-sectional area of ​​the cylinder.

[0019] In this embodiment, the acquisition of pressure information of the hydraulic system of the compression mechanism is as follows: when the compression mechanism operates, the pressure in its hydraulic system changes, and the pressure sensing device continuously acquires and stores the pressure in the hydraulic system. The sensors used to detect the hydraulic system of the compression mechanism can be pressure relays, pressure sensors, or flow sensors; preferably, pressure relays are used for hydraulic system detection. In step S109, it is determined whether, after two cycles of steps S101-S108, the pressure sensing device senses the set pressure value P twice consecutively in the corresponding steps. For the pressure detection of the hydraulic system, the pressure value detected under each action is independent, and the counting is also independent, without affecting each other. For example, in step S100, the scraper is opened, at which time the pressure of the hydraulic system changes. The pressure sensing device detects the pressure of the hydraulic system. When the pressure sensing device senses the pressure value P, it counts. The first count corresponding to the scraper opening action is 1. When the pressure... If the sensing device does not detect the pressure value P, it will not count. After running to step S103, the pressure sensing device detects the pressure of the hydraulic system. When the pressure sensing device detects the pressure value P, it counts. The first count for the sliding plate going down is 1. The first count for the scraper opening action and the first count for the sliding plate going down are 1. These two counts are not added together, but exist independently. When running to the scraper opening action for the second time, when the pressure sensing device detects the pressure value P and the second count for the scraper opening action is 2, the voice speaker is triggered to sound a full box alarm.

[0020] In this embodiment, step S109 further includes: If, after two cycles, the first proximity switch fails to receive the arrival signal I1 twice in a row and the waiting time T1 reaches the preset time T1', the voice speaker will issue a fault alarm for the first proximity switch. If, after two cycles, the second proximity switch fails to receive the arrival signal I2 twice in a row and the waiting time T2 reaches the preset time T2', the voice speaker will issue a fault alarm for the second proximity switch. If, after two cycles, the third proximity switch fails to receive the arrival signal I3 twice in a row and the waiting time T3 reaches the preset time T3', the voice speaker will issue a fault alarm for the third proximity switch. If, after two cycles, the fourth proximity switch fails to receive the arrival signal I4 twice consecutively and the waiting time T4 reaches the preset time T4', the voice speaker will issue a fault alarm for the fourth proximity switch.

[0021] When the voice speaker plays a voice message, the alarm content of the corresponding proximity switch is different. The corresponding proximity switch can be accurately located based on the different voice alarm content, so that precise repair can be performed without the operator having to check each proximity switch one by one.

[0022] When controlling the speaker to play a voice message, the control logic is as follows: When a certain action of the compression mechanism is executed for the first time, it checks whether the corresponding proximity switch receives a signal. If a signal is received, the proximity switch count is reset to zero, indicating that the proximity switch is working normally. If no signal is received, it checks whether the pressure relay has received pressure during the transition from the current action to the next action, and whether the pressure relay pressure has reached the pressure relay's set pressure P. If the set pressure P is reached, a full-box alarm is triggered, counting begins, and the next action is executed. If the set pressure P is not reached during the transition from the current action to the next action, it checks the time required for the transition. If the time reaches the set time T, a proximity switch fault is detected, counting begins, and the next action is executed. This process is repeated until all the actions of the compression mechanism are completed. At the start of the second cycle, a certain action of the compression mechanism is executed for the second time. According to the above control logic, when the full-box alarm count occurs twice consecutively, it is considered full, and the speaker plays a voice message indicating a full box. When the proximity switch fault count occurs twice consecutively, the speaker plays a voice message indicating a proximity switch fault.
