[0019] Figure 2 A schematic diagram of the circuit principle of a deviation detection method according to an embodiment of the present application is shown. DETAILED DESCRIPTION
[0020] The technical solutions in this application will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of this application. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other without conflict.
[0021] Belt conveyor equipment is a kind of conveying equipment widely used in various fields of industrial production and logistics transportation. During the operation of belt conveyor equipment, the deviation of the conveyor belt not only affects the quality of the conveyed materials, but also if the conveyor belt frequently deviates, it may cause the belt conveyor equipment to shut down frequently, thus affecting the life of the belt conveyor. Therefore, the deviation detection method plays a vital role in the belt conveyor. The deviation detection method is mainly used to detect and prevent the conveyor belt from deviating during operation, thereby ensuring the safety and stability of the conveying process.
[0022] The present application provides a deviation detection method, a deviation detection device and a computer storage medium using the deviation detection method. The deviation detection device and deviation detection method of the present application can detect whether the conveyor belt of the belt conveyor equipment is deviated. The deviation detection device includes a first signal receiving component and a second signal receiving component, and the deviation detection device is, for example, a deviation switch. The belt conveyor equipment includes a conveyor belt. Among them, the conveyor belt can be a belt, a rubber belt, a plastic belt or a cloth belt, etc., and the present application does not make specific restrictions on this, as long as the technical principle of the present application can be realized. In the present application, if there is no additional explanation, "belt" will be used as an example of a conveyor belt, "belt conveyor equipment" will be used as an example of a belt conveyor equipment, and "deviation switch" will be used as an example of a deviation detection device.
[0023] In the present application, the deviation switch can be installed on the side wall of the belt conveyor device at a certain distance (e.g., 1m) from the driving wheel or driven wheel of the device, the contact component of the deviation switch faces the belt, the belt and the contact component maintain a certain distance (e.g., the distance can be set to 1mm), the first signal receiving component of the deviation switch is set between the contact component and the second signal receiving component, the second signal receiving component is spaced a certain distance (e.g., 10mm) from the first signal receiving component, and the second signal receiving component is far away from the contact component. When the belt is not deviated (i.e., in the initial state), the belt and the contact component maintain a certain distance, and both the first signal receiving component and the second signal receiving component of the deviation switch can receive signals.
[0024] The deviation detection method 100 of the present application is described in detail below with reference to the accompanying drawings. Figure 1 A flow chart of a deviation detection method according to an embodiment of the present application is shown. Figure 2 The circuit principle diagram of the deviation detection method according to an embodiment of the present application is shown. The deviation detection method 100 includes steps S101 to S102. Steps S101 to S102 will be described below.
[0025] In step S101, a first voltage value and a second voltage value are collected, wherein the first voltage value is the voltage value of the first signal receiving component, and the second voltage value is the voltage value of the second signal receiving component.
[0026] In the present application, the deviation level of the belt is determined by the signal strength or signal status of the first signal receiving component and the second signal receiving component, so the first voltage value and the second voltage value need to be collected first.
[0027] The first voltage value refers to the voltage value of the first signal receiving component, and the first voltage value reflects the signal strength or signal state received by the first signal receiving component. The second voltage value refers to the voltage value of the second signal receiving component, and the second voltage value reflects the signal strength or signal state received by the second signal receiving component.
[0028] In step S101, the first voltage value and the second voltage value may be collected by a single chip microcomputer.
[0029] For example, the single-chip microcomputer is first initialized, and then the analog voltages of the first signal receiving component and the second signal receiving component are collected by the single-chip microcomputer, and the analog voltages of the first signal receiving component and the second signal receiving component are converted into digital voltages by an analog-to-digital converter (ADC), thereby obtaining a first voltage value and a second voltage value. In the present application, in order to ensure that the analog voltage value collected by the single-chip microcomputer is more accurate, a signal synchronization element (such as a crystal oscillator, a clock generator) can be added to achieve signal synchronization.
[0030] In step S101, after collecting the first voltage value and the second voltage value, the deviation detection method further includes: performing a preprocessing operation on the first voltage value and the second voltage value. For example, the first voltage value and the second voltage value may be filtered to remove noise and interference signals therein to ensure the accuracy and reliability of the data. The first voltage value and the second voltage value may also be normalized to convert the first voltage value and the second voltage value into a uniform numerical range to facilitate subsequent analysis and processing. In addition, the first voltage value and the second voltage value may also be smoothed to reduce fluctuations and mutations in the data and make the data smoother and more stable. By preprocessing the first voltage value and the second voltage value, the accuracy of the first voltage value and the second voltage value may be improved.
[0031] It can be understood that the above description of the first voltage value and the second voltage value is only exemplary, and those skilled in the art can set the collection method and processing operation of the first voltage value and the second voltage value according to actual needs, as long as the technical principles of the present application can be implemented.
[0032] Then, the process proceeds to step S102. In step S102, the first voltage value and the second voltage value are respectively compared with a predetermined voltage threshold value to determine the deviation level of the conveyor belt, wherein if the first voltage value and the second voltage value are both higher than the predetermined voltage threshold value, it is determined that the conveyor belt has not deviated; if the first voltage value is lower than the predetermined voltage threshold value and the second voltage value is higher than the predetermined voltage threshold value, it is determined that the conveyor belt is in the first level of deviation.
[0033] As described above, the collected first voltage value and the second voltage value are respectively compared with the preset voltage threshold, and the belt deviation level is determined by this comparison. That is, the belt deviation level is determined based on the difference between the first voltage value and the preset voltage threshold, and the difference between the second voltage value and the preset voltage threshold.
[0034] If both the first voltage value and the second voltage value are higher than a predetermined voltage threshold (for example, the predetermined voltage threshold is 5V), it means that the voltage value of the first signal receiving component and the voltage value of the second signal receiving component are both within the normal range, thereby judging that the belt has not deviated. Specifically, if the belt has not deviated, the signal strengths received by the first signal receiving component and the second signal receiving component should be balanced and stable, and the corresponding voltage values will also remain within the normal range. For example, the predetermined voltage threshold is set to 5V, while the first voltage value actually collected is 5.2V and the second voltage value is 5.1V, both of which are higher than 5V, indicating that the signal of the first signal receiving component and the signal of the second signal receiving component are both in a normal state, and the belt has not deviated.
[0035] If the first voltage value is lower than the predetermined voltage threshold, and the second voltage value is higher than the predetermined voltage threshold, it is determined that the conveyor belt is in the first level of deviation. For example, the predetermined voltage threshold is set to 5V, the first voltage value actually collected is 3V, and the second voltage value is 5.1V, indicating that the second signal receiving component is in a normal state, and the voltage value of the first signal receiving component is lower than 5V, indicating that the belt has shifted, and the signal strength received by the first signal receiving component has weakened, resulting in a decrease in the first voltage value, thereby determining that the belt is in the first level of deviation. In this embodiment, the first level of deviation can be set, for example, as a lateral displacement of the belt of 1mm.
[0036] In the present application, the deviation detection method 100 further includes: if the first voltage value and the second voltage value are both lower than the predetermined voltage threshold, it is determined that the conveyor belt is in a secondary deviation.
[0037] For example, the predetermined voltage threshold is set to 5V, and the first voltage value actually collected is 3V, and the second voltage value is 4V, both of which are lower than 5V, indicating that the belt continues to deviate after the first deviation occurs, causing the first signal receiving component and the second signal receiving component to fail to receive signals normally, thereby determining that the belt is in the second deviation. In the present application, the second deviation can be set, for example, as a 10mm lateral displacement of the belt.
[0038] It is understandable that the predetermined voltage threshold may be a specific value (e.g., a voltage threshold of 5V) or a range (e.g., a voltage threshold of 4.5V to 5.5V), and may be set according to specific application scenarios. The above settings of the primary deviation and the secondary deviation are only exemplary, and those skilled in the art may set the primary deviation and the secondary deviation according to actual needs, as long as the technical principles of the present application can be implemented.
[0039] In step S102, when it is determined that the conveyor belt is in the first level of deviation, the deviation detection method further includes: outputting a first level alarm signal; when it is determined that the conveyor belt is in the second level of deviation, the deviation detection method further includes: outputting a second level alarm signal.
[0040] For example, when the belt deviation reaches the preset first-level deviation standard, the belt is in the first-level deviation (for example, the belt deviates by 1mm), and a first-level alarm signal is output. If the belt deviation is further aggravated in the first-level deviation situation and reaches the preset second-level deviation standard, the belt is in the second-level deviation (for example, the belt deviates by 10mm), and a second-level alarm signal is output. The first-level alarm signal and the second-level alarm signal can be issued through the alarm to remind the staff to pay attention to the deviation of the belt. At the same time, the time and location of the deviation can be recorded for subsequent analysis and processing.
[0041] In the deviation detection method of the present application, the output of the primary alarm signal and the output of the secondary alarm signal can be controlled by a single chip microcomputer.
[0042] When it is determined that the belt is in the first stage of deviation, the microcontroller controls the signal circuit through the switch controller to output a first-level alarm signal (for example, a 24V alarm signal). When it is determined that the belt is in the second stage of deviation, the microcontroller controls the signal circuit through the switch controller to output a second-level alarm signal (for example, a 24V alarm signal).
[0043] In the present application, the deviation detection device may be pre-set with a status indicator light (also referred to as a status display light). The status indicator light is, for example, an LED light. Accordingly, the display color of the status indicator light may be set according to the output primary alarm signal and secondary alarm signal to provide a visual prompt. For example, for a primary alarm signal (i.e., primary deviation), the LED light displays yellow; for a secondary alarm signal (i.e., secondary deviation), the LED light displays red. In addition, the LED light may be set to display green when the belt is not deviating or the deviation disappears, and at this time, neither the primary alarm signal nor the secondary alarm signal is output.
[0044] In addition, in order to provide the staff with a more intuitive visual prompt, a light guide can be provided on the housing of the deviation switch, and the light guide is arranged opposite to the status indicator light to guide the light of the status indicator light. The light guide can transmit light from one light source to another position, so the light of different colors (red, yellow, green) emitted by the LED lamp can be transmitted to the housing surface of the deviation switch through the light guide.
[0045] The above description of the status indicator light and the light guide is merely exemplary, and those skilled in the art may configure the status indicator light and the light guide according to actual needs, as long as the technical principles of the present application can be implemented.
[0046] In the present application, the deviation detection device also includes: a first signal transmitting component and a second signal transmitting component, the first signal transmitting component is used to transmit a first signal to the first signal receiving component, and the second signal transmitting component is used to transmit a second signal to the second signal receiving component.
[0047] For example, the first signal transmitting component of the deviation detection device is arranged relative to the first signal receiving component, and the second signal transmitting component is arranged relative to the second signal receiving component, and the first signal transmitting component and the second signal transmitting component transmit signals to the corresponding first receiving component and the second receiving component respectively. Specifically, the main function of the first signal transmitting component is to transmit a signal to the first signal receiving component, and the main function of the second signal transmitting component is to transmit a signal to the second signal receiving component. When the first signal receiving component receives the first signal, the single-chip microcomputer converts the analog voltage of the collected first signal into a digital voltage (for example, a first voltage value) through an analog-to-digital converter, and when the second signal receiving component receives the second signal, the single-chip microcomputer converts the analog voltage of the collected second signal into a second voltage value through an analog-to-digital converter.
[0048] It is understandable that the first signal transmitting component and the second signal transmitting component can be an infrared transmitting tube or a laser transmitter, and the first signal receiving component and the second signal receiving component can be an infrared receiving tube or a laser receiver. If the first signal transmitting component is an infrared transmitting tube, the first signal receiving component is an infrared receiving tube; if the first signal transmitting component is a laser transmitter, the first signal receiving component is a laser receiver. Those skilled in the art can select the first signal transmitting component, the first signal receiving component, the second signal transmitting component and the second signal receiving component according to actual needs, as long as the technical principles of the present application can be implemented.
[0049] In step S102, when the conveyor belt is in the first level of deviation, the first signal receiving component cannot receive the first signal emitted by the first signal emitting component, and the second signal receiving component receives the second signal emitted by the second signal emitting component.
[0050] For example, when the belt deviates by one level (for example, the belt deviates by 1 mm), the first signal emitted by the first signal transmitting component is blocked, causing the first signal receiving component to be unable to receive the first signal, while the second signal emitted by the second signal transmitting component is not blocked, so the second signal receiving component can receive the second signal.
[0051] In step S102, when the conveyor belt is in the secondary deviation condition, the first signal receiving component cannot receive the first signal emitted by the first signal emitting component, and the second signal receiving component cannot receive the second signal emitted by the second signal emitting component.
[0052] For example, when the belt deviates to the first level, the belt continues to deviate, and the lateral offset of the belt further increases, thereby reaching the predetermined second-level deviation standard. At this time, the first signal emitted by the first signal emitting component and the second signal emitted by the second signal emitting component are both blocked, so the first signal receiving component and the second signal receiving component cannot receive any signal.
[0053] Reference Figure 2 , the detection process of the deviation detection method 100 is described in detail.
[0054] The deviation switch includes a first signal transmitting component, a first signal receiving component, a second signal transmitting component, a second signal receiving component, a single chip microcomputer, a switch controller and a status display light. Figure 2 As shown, the first signal transmitting component and the second signal transmitting component of the deviation switch are connected to a first power supply (for example, a 5V voltage), and the first power supply is stepped down (for example, a 3.3V voltage) to supply power to the single-chip microcomputer, the first signal receiving component, and the second signal receiving component. The single-chip microcomputer collects the analog voltages of the first signal receiving component and the second signal receiving component, and converts the analog voltages of the first signal receiving component and the second signal receiving component into digital voltages through an ADC (analog-to-digital converter). The deviation level of the belt is determined by comparing the collected voltage value of the first signal receiving component with the voltage value of the second signal receiving component. When the deviation of the belt is detected, the single-chip microcomputer controls the signal circuit to output an alarm signal through the switch controller. At the same time, the single-chip microcomputer controls the lighting of the status indicator light to remind the staff of the current deviation level of the belt. In this embodiment, in order to ensure that the analog voltage value collected by the single-chip microcomputer is more accurate, a signal synchronization element (for example Figure 2The crystal oscillator shown in the figure is used to achieve signal synchronization.
[0055] The deviation detection method 100 provided in the present application is used to detect the deviation level of the conveyor belt. By comparing the collected first voltage value and the second voltage value with the predetermined voltage threshold respectively and judging the deviation level of the conveyor belt, if the first voltage value and the second voltage value are both higher than the predetermined voltage threshold, it is judged that the conveyor belt has not deviated; if the first voltage value is lower than the predetermined voltage threshold and the second voltage value is higher than the predetermined voltage threshold, it is judged that the conveyor belt is in the first level of deviation. The present application judges the deviation level of the conveyor belt by comparing the voltage values, thereby solving the problem that the deviation level of the conveyor belt cannot be detected in the existing deviation detection method.
[0056] Furthermore, the deviation detection method 100 provided in the present application can further detect the deviation state of the conveyor belt through the first voltage value and the second voltage value. If the first voltage value and the second voltage value are both lower than the predetermined voltage threshold, it is determined that the conveyor belt is in the second level of deviation.
