[0043] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments. The details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. The following embodiments and features therein may be combined with one another without conflict.

[0044] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. The drawings only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0045] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring the embodiments of the present invention.

[0046] See Figure 1 , Figure 1 This is a flow chart of a sensor automatic inspection method provided by an embodiment of the present invention, as shown in FIG. Figure 1 As shown, in an exemplary embodiment, the automatic inspection method for sensors of the present invention may include steps S110 to S130, which are described in detail as follows:

[0047] Step S110: Acquire test data and real-time data of sensor 2.

[0048] Specifically, sensor 2's test data includes the normal operating time of a single tie 3 and the normal interval between two adjacent tie 3s. Sensor 2's real-time data includes the real-time operating time of a single tie 3, the real-time interval between two adjacent tie 3s, and the number of sensing times by sensor 2 during the benchmark operating time. It should be noted that each time sensor 2 detects a tie 3, it emits a sensing signal, and the inspection module records the number of sensing times.

[0049] In one embodiment of the present invention, before spot checking the sensors 2 on the production line, test data of the sensors 2 is first obtained. To obtain the test data, the sensors 2 are required to monitor the normally operating tie pieces 3, thereby obtaining the normal operating time of a single tie piece 3 and the normal interval time between two adjacent tie pieces 3.

[0050] In one embodiment of the present invention, after the test data collection of the sensor 2 is completed, the real-time data of the sensor 2 can be collected, that is, the spot inspection operation of the sensor 2 begins.

[0051] For example, the sensor 2 may be configured as a hot metal detector or the like.

[0052] Step S120 : determining the reference data of sensor 2 based on the test data.

[0053] Specifically, the reference data of the sensor 2 includes a reference running time of a single tying member 3 and a reference interval time between two adjacent tying members 3 .

[0054] In one embodiment of the present invention, first, in order to improve the reliability of the test data of the sensor 2, it is necessary to monitor a plurality of continuously normally operating components 3, thereby obtaining a plurality of test data. Subsequently, the average value of the normal operating time of the plurality of components 3 is calculated, and the average value is used as the reference operating time of the component 3. At the same time, the plurality of normal intervals of the plurality of normally operating components 3 are compared, and the minimum value of the plurality of normal intervals is determined, and the normal interval time of the minimum value is used as the reference interval time of the component 3. It should be noted that when monitoring a plurality of continuously normally operating components 3, if any of the plurality of continuously normally operating components 3 has an abnormal operation, in order to improve the reliability and accuracy of the test data of the sensor 2, the sensor 2 needs to be reset and a new round of data collection needs to be carried out again.

[0055] For example, when collecting the test data of the sensor 2 , at least three or more continuously running binding members 3 are monitored.

[0056] Step S130: determining the fault information of the sensor 2 according to the reference data and the real-time data.

[0057] In one embodiment of the present invention, after the baseline data of the binding member 3 is determined, the sensor 2 can be inspected. In this process, the real-time data of the sensor 2 is obtained, and then the real-time data of the sensor 2 is compared with the baseline data to determine the fault information of the sensor 2.

[0058] In one example, the benchmark running time and the real-time running time are compared to obtain the difference between the two, and further obtain the absolute value of the difference. If the absolute value is less than the first preset value and the number of sensing times is less than or equal to 1, it indicates that sensor 2 is operating normally. If the number of sensing times is greater than or equal to 2, it is determined that sensor 2 has a first fault. Exemplarily, the first fault may be a flash fault of sensor 2. If the absolute value is greater than or equal to the second preset value, it is determined that sensor 2 has a second fault. Exemplarily, the second fault may be a long-light fault of sensor 2. If the real-time interval time is less than the benchmark interval time, and the number of sensing times is greater than or equal to 1, or the absolute value is greater than or equal to the third preset value, it is determined that sensor 2 has a third fault. Exemplarily, the third fault may be an interference fault in the detection channel of sensor 2. If the real-time interval time is greater than or equal to the fourth preset value, sensor 2 is reset.

[0059] For example, a range of 1%-5% of the reference operating time of the tie 3 is used as the base value, wherein the first preset value can be set to the base value, the second preset value can be set to 10 times the base value, the third preset value can be set to 8 times the base value, and the fourth preset value can be set to 10 times the base interval time.

[0060] To sum up, the solution of this embodiment obtains the sensor's test data to obtain the sensor's baseline data; and obtains the sensor's real-time data, and then determines the sensor's fault information based on the sensor's baseline data and real-time data, avoiding manual sensor fault detection, which is beneficial to improving the work efficiency of the binding production line and thus helping to increase the output of binding parts.

[0061] See Figure 2 In an exemplary embodiment, the present invention further provides a sensor-based automatic spot inspection device, comprising a piece-binding conveyor line 1, a sensor 2, and a spot inspection module. The piece-binding conveyor line 1 is configured to convey pieces 3. The sensor 2 is mounted on the piece-binding conveyor line 1 and configured to inspect the pieces 3 on the piece-binding conveyor line 1. The spot inspection module is electrically connected to the sensor 2 and configured to inspect the sensor 2 to determine any faults in the sensor 2, thereby ensuring the normal operation of the pieces 3 on the piece-binding conveyor line 1 and improving the production efficiency of the pieces 3.

[0062] In one embodiment of the present invention, the inspection module includes a timer and a counter. The timer measures the time between two adjacent sensing signals from sensor 2, thereby determining the normal operating time, normal interval time, real-time operating time, and real-time interval time of two adjacent binding members 3. The counter counts the number of sensing signals from sensor 2, thereby determining the number of sensing times by sensor 2 within the reference operating time.

[0063] In one embodiment of the present invention, the inspection module is electrically connected to the alarm module. When the inspection module determines the first fault, the second fault and the third fault of the sensor 2, the inspection module controls the alarm module to issue an alarm signal for the first fault, the second fault and the third fault respectively.

[0064] In one embodiment of the present invention, the inspection module further includes a resetter mounted on the bundle conveyor line 1, the resetter being electrically connected to the sensor 2. When any bundle 3 among the plurality of bundles 3 operating continuously and normally experiences an abnormality, or when the sensor 2 detects that the real-time interval between bundles 3 is greater than or equal to a fourth preset value, the inspection module controls the resetter to reset the sensor 2.

When the processor 320 executes the computer program, the steps of the automatic sensor inspection method of any of the above embodiments are implemented.

When executed by a computer processor, the computer program causes the computer to perform the aforementioned automatic sensor inspection method.
