[0014] The main solution of the embodiment of the present application is: by controlling the action of the compression mechanism, it is determined whether the proximity switch in each action receives the in-place signal, and whether the pressure sensing device senses the set pressure value. If the proximity switch receives the in-place signal or the pressure relay reaches the set pressure value or the waiting time reaches the preset time, then proceed to the next step. After the same action cycle is executed twice, it is determined whether the pressure sensing device senses the set pressure value twice in a row, the proximity switch does not receive the in-place signal and the waiting time reaches the preset time. If the pressure sensing device senses the set pressure value twice in a row after two cycles, the voice speaker will issue a full tank alarm. If the proximity switch does not receive the in-place signal twice in a row and the corresponding waiting time reaches the preset time, the voice speaker will issue a proximity switch fault alarm. This reminds people that the signal detection switch needs to be repaired, and a voice reminder is played in time when the tank is full to prevent overload from damaging the mechanical structure.
[0015] In the prior art, garbage trucks generally use position signal switches as reversing switches for compression mechanisms. Due to the harsh working conditions of compression mechanisms, signal switches are easily damaged by corrosion or external impact, resulting in abnormal reversing. It is difficult for operators to find and handle faults in time. If they are not found and handled in time, it will cause damage to the machinery, safety accidents, and affect people's safety.
[0016] The present application provides a solution that can perform self-check on the compression mechanism signal switch and issue an alarm, so that the operator can know more clearly whether the compression mechanism signal switch is normal.
[0017] To this end, the present invention provides a compression mechanism signal switch self-test method. Figures 1 to 3 In one embodiment of the present invention, the compression mechanism signal switch self-test method includes steps S100-S109, wherein: S101, control the scraper to open; S102, judging whether the first proximity switch receives the in-position signal I1, judging whether the pressure sensing device senses the pressure value P, and judging whether the waiting time T1 reaches the preset time T1'. If the first proximity switch receives the in-position signal I1 or the pressure relay reaches the set pressure value P or the waiting time T1 reaches the preset time T1', then proceeding to step S103; S103, control the slide board downward S104, judging whether the second proximity switch receives the in-position signal I2, judging whether the pressure sensing device senses the pressure value P, and judging whether the waiting time T2 reaches the preset time T. If the second proximity switch receives the in-position signal I2 or the pressure relay reaches the set pressure value P or the waiting time T2 reaches the preset time T2', then proceeding to step S105; S105, control the scraper to close; S106, judging whether the third proximity switch receives the in-position signal I3, judging whether the pressure sensing device senses the pressure value P, and judging whether the waiting time T3 reaches the preset time T. If the third proximity switch receives the in-position signal I3 or the pressure relay reaches the set pressure value P or the waiting time T3 reaches the preset time T3', then proceeding to step S105; S107, controlling the slide plate to move upward; S108, judging whether the fourth proximity switch receives the in-position signal I4, judging whether the pressure sensing device senses the pressure value P, and judging whether the waiting time T4 reaches the preset time T. If the fourth proximity switch receives the in-position signal I4 or the pressure relay reaches the set pressure value P or the waiting time T4 reaches the preset time T4', then entering step S101; S109, after judging steps S101-S108 are cycled twice, whether the pressure sensing device senses the set pressure value P twice in succession, the first proximity switch does not receive the in-place signal I1 and the waiting time T1 reaches the preset time T1', the second proximity switch does not receive the in-place signal I2 and the waiting time T2 reaches the preset time T2', the third proximity switch does not receive the in-place signal I3 and the waiting time T3 reaches the preset time T3', the fourth proximity switch does not receive the in-place signal I4 and the waiting time T4 reaches the preset time T4'. If the pressure sensing device senses the set pressure value P twice in succession after two cycles, the voice speaker will give a full tank alarm. If the proximity switch does not receive the in-place signal twice in succession and the corresponding waiting time reaches the preset time T, the voice speaker will give a proximity switch failure alarm.
[0018] In this embodiment, the actions of the compression mechanism include the opening of the scraper, the downward movement of the slide, the closing of the scraper and the upward movement of the slide. In the action of the opening of the scraper, the first proximity switch is used to detect whether the scraper is in place. In the action of the downward movement of the slide, the second proximity switch is used to detect whether the slide is in place. In the action of the closing of the scraper, the third proximity switch is used to detect whether the scraper is in place. In the action of the slide, the fourth proximity switch is used to detect whether the slide is in place. In this embodiment, the detection of the action of the compression mechanism and the detection of the hydraulic system are independent of each other and do not affect each other. When the compression mechanism is in action, the timing starts, that is, the waiting time. The timing corresponds to the timing of the compression mechanism under the corresponding action. For example, when controlling the opening of the scraper, counting is performed. When the first proximity switch receives the in-place signal, the counting stops and is counted as the waiting time T1. The preset time is manually preset and set by the operator. The compression mechanism includes a cylinder body for controlling the opening and closing of the scraper and the sliding of the slide, and a hydraulic power system that provides power to the cylinder body. The preset time follows the following rule: 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 pressure information of the hydraulic system of the compression mechanism is obtained in that when the compression mechanism is actuated, the pressure in its hydraulic system will change, and the pressure sensing device continuously obtains the pressure in the hydraulic system and stores it. The sensor used in detecting the hydraulic system of the compression mechanism may be a pressure relay, a pressure sensor, or a flow sensor. Preferably, a pressure relay is used for hydraulic detection of the compression mechanism. In step S109, it is determined whether the pressure sensing device senses the set pressure value P twice in a row in the corresponding step after steps S101-S108 are cycled twice. In the pressure detection of the hydraulic system, the pressure value detected under each action is independent and exists independently when counting, and does not affect each other. For example, in step S100, the scraper is controlled to open. At this time, the pressure of the hydraulic system will change. 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 sense 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 senses the pressure value P, it counts. The first count of the corresponding downward movement of the slide board is 1, and the first count of the scraper opening movement is 1 and the first count of the slide board downward movement is 1. These two counts are not accumulated but exist independently. When the scraper is opened for the second time, when the pressure sensing device senses the pressure value P and the second count of the corresponding scraper opening movement is 2, the voice speaker is triggered to alarm for a full tank.
[0020] In this embodiment: Step S109 also includes: If after two cycles, the first proximity switch fails to receive the arrival signal I1 twice in succession and the waiting time T1 reaches the preset time T1', the voice speaker will issue a first proximity switch failure alarm; If after two cycles, the second proximity switch fails to receive the arrival signal I2 twice in succession and the waiting time T2 reaches the preset time T2', the voice speaker will issue a second proximity switch failure alarm; If after two cycles, the third proximity switch fails to receive the arrival signal I3 twice in succession and the waiting time T3 reaches the preset time T3', the voice speaker will issue a third proximity switch failure alarm; If after two cycles, the fourth proximity switch fails to receive the arrival signal I4 twice in succession and the waiting time T4 reaches the preset time T4', the voice speaker issues a fourth proximity switch failure alarm.
[0021] When the voice speaker plays voice, the alarm content of the corresponding proximity switch is different. The corresponding proximity switch can be accurately found according to the different voice alarm contents, and accurate maintenance can be performed without the operator having to check the proximity switches one by one.
[0022] When controlling the voice speaker to play voice, its control logic is that when a certain action of the compression mechanism is executed for the first time, it is judged whether the corresponding proximity switch receives a signal. When a signal is received, the proximity switch count is reset, which means that the proximity switch works normally. When no signal is received, it is judged whether the pressure of the pressure relay is received during the process from the current action to the next action, and whether the pressure of the pressure relay reaches the pressure P set by the pressure relay. When the set pressure P is reached, the full tank alarm is counted and the next action is controlled to be executed. When the current action is not received during the process from the next action to the set pressure P, it is judged that the time required for the previous action to run to the next action is counted. When the time reaches the set time T, the proximity switch fault is counted and the next action is controlled to be executed. In this way, the action of the compression mechanism is executed in a cycle. At the beginning 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 tank alarm counts twice in a row, it is regarded as a full tank, and the voice speaker is controlled to play the voice as a full tank. When the proximity switch fault counts twice in a row, the voice speaker is controlled to play the voice, and the voice content is a proximity switch fault.
