Description of the Drawings

Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other accompanying drawings can be obtained based on these drawings.

[0016] Figure 1 It is a schematic diagram of the system structure connection of the present invention. Specific embodiments

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0018] Please refer to Figure 1 As shown, an on-line monitoring system for the state of a gate includes: a real-time gate monitoring module, a gate component monitoring unit, and an early warning terminal.

[0019] The real-time gate monitoring module is respectively connected to the gate component monitoring unit and the early warning terminal.

[0020] The real-time gate monitoring module is used to perform real-time monitoring on the gate under warehouse application and analyze the state of the gate during application.

[0021] In a specific embodiment, the analysis of the phenomenon state of the gate during application is as follows: Based on the camera installed at the gate position, the opening images and closing images of the warehouse gate corresponding to each time period during application are obtained in real time, and the corresponding manifestations of the gate are obtained from the opening images and closing images of the gate corresponding to each time period respectively. If the instantaneous drop phenomenon of the gate appears in a certain time period after the gate is opened in the opening image, it is determined that the gate state is abnormal, and information is sent to the gate component monitoring unit to automatically perform the component detection of the gate. When the gate cannot complete the closing task at one time during the closing process in a certain time period in the closing image, there is redundancy at the bottom of the gate after closing, or foreign objects are detected at the bottom of the gate from the closing image but the gate does not activate the foreign object alarm and continues to execute the closing task, resulting in the manifestation of unable to close tightly, it is determined that the gate state is abnormal, and information is sent to the gate component monitoring unit to automatically perform the component detection of the gate. By comprehensively analyzing the above, the abnormal states corresponding to the gate are obtained, and the state of the gate during application is analyzed accordingly.

[0022] The gate component monitoring unit includes a gate component screening module, a gate component monitoring module, a gate component analysis module, and a gate manual switch monitoring module.

[0023] The gate component screening module is used to screen out the components to be monitored corresponding to the gate according to the reference matching results of each historical abnormal phenomenon corresponding to the gate.

[0024] It should be noted that the components to be detected include relays, limiters, brake discs, tubular motors, guide rails, rollers and sensors.

[0025] It should also be noted that the abnormal component sets refer to the abnormal state detections of each historical gate, and the detection results corresponding to each abnormal state monitoring show that the cause is a certain component for many times. By analogy, the abnormal component sets corresponding to each historical abnormal state are summarized. For example, for the phenomenon state monitoring of the gate 10 times, when the gate shows the phenomenon of instantaneous dropping or automatic dropping 10 times, and the analysis results of 8 times are that the gate relay fails, it indicates that after the gate shows the phenomenon of instantaneous dropping or automatic dropping, the relay component needs to be monitored correspondingly.

[0026] In a specific embodiment, the process of screening out the components to be monitored corresponding to the gate is as follows: Compare each abnormal state corresponding to the gate with the abnormal component sets corresponding to each historical abnormal state stored in the database. If a certain abnormal state corresponding to the gate is within a certain abnormal component set corresponding to a certain historical abnormal state stored in the database, then use this abnormal component as the component to be monitored when this abnormal state of the gate appears. By analogy, compare to obtain each component to be monitored, and thus screen out the components to be monitored corresponding to the gate.

[0027] The gate component monitoring module is used to obtain the monitoring information of the components to be detected corresponding to the gate according to the positions of the components to be detected corresponding to the gate.

[0028] It should be noted that the sensors that are automatically turned on when the gate is in the open state include voltage sensors, signal generators, thickness gauges and temperature sensors.

[0029] In a specific embodiment, the process of obtaining the monitoring information of the components to be detected corresponding to the gate is as follows: Based on the state characteristics presented in the opening images and closing images of the gate at each time period, the obtaining process is further divided into the monitoring of the components to be monitored when the gate is in the open state and the detection of the components to be detected when the gate is in the closed state.

[0030] Monitor each component to be monitored when the gate is in the open state, and set the allowable values of the reference monitoring parameters corresponding to each component to be monitored. By automatically turning on the sensors at the positions of each component to be monitored, the monitoring information of each component to be monitored in the open state can be obtained. The monitoring information includes coil voltage, control signal, mechanical wear depth, and contact temperature. When the value of the monitoring parameter detected by the sensor corresponding to a certain component to be monitored exceeds the set allowable value of the reference monitoring parameter, record the corresponding exceeded parameter of the component to be monitored, so as to monitor the monitoring information corresponding to each component to be monitored when the gate is in the open state.

[0031] In a specific embodiment, the detection of each component to be monitored when the gate is in the closed state is obtained as follows: Set the reference values of the reference detection parameters corresponding to each component to be detected when the gate is in the closed state. By automatically turning on the sensors at the positions of each component to be detected, the sensors include displacement sensors, force sensors, and vibration sensors, and the detection information of each component to be detected in the closed state can be obtained. The detection information includes inclination, friction, and noise. When the value of the detection parameter detected by the sensor corresponding to a certain component to be detected exceeds the set reference value of the detection parameter, record the corresponding exceeded parameter of the component to be detected, and combine the monitoring information corresponding to each component to be monitored when the gate is in the open state, so as to obtain the monitoring information corresponding to each component to be detected of the gate.

[0032] The gate component analysis module is used to judge the monitoring status of each component to be detected corresponding to the gate.

[0033] It should be noted that based on the monitoring information of each component to be monitored when the gate is in the open state, the required monitoring judgment features corresponding to each component to be monitored when the gate is in the open state are extracted. Compare the required monitoring judgment features corresponding to each component to be monitored when the gate is in the open state with the feature sets corresponding to each prediction model. If the required monitoring judgment feature corresponding to a certain component to be monitored when the gate is in the open state is within the feature set corresponding to a certain prediction model, then use this prediction model as the prediction model for judging the monitoring status of each component to be monitored when the gate is in the open state. Similarly, the prediction model for the monitoring status of each component to be monitored when the gate is in the closed state can be obtained, so as to judge the monitoring status of each component to be monitored corresponding to the gate.

[0034] In a specific embodiment, the judgment of the monitoring status of each component to be monitored corresponding to the gate is as follows: Extract the monitoring information of each component to be monitored based on the open state of the gate and the detection information of each component to be detected based on the closed state of the gate respectively.

[0035] Input the monitoring information into the prediction model to obtain the monitoring coefficients corresponding to each component to be monitored under the gate opening state. When the predicted monitoring result corresponding to a component to be monitored under the gate opening state is 0, it is determined that the state of the component to be monitored under the gate opening state is normal. If the predicted monitoring result corresponding to a component to be monitored under the gate opening state is 1, it is determined that the state of the component to be monitored under the gate opening state is abnormal, and so on to judge the monitoring states corresponding to each component to be monitored under the gate opening state.

[0036] In a specific embodiment, the extraction of the detection information of each component to be detected under the gate closing state and the specific analysis process are as follows: Input the detection information into the prediction model to obtain the detection coefficients corresponding to each component to be detected under the gate closing state. When the predicted output result corresponding to a component to be detected under the gate closing state is 0, it is determined that the state of the component to be detected under the gate closing state is normal. If the predicted output result corresponding to a component to be detected under the gate closing state is 1, it is determined that the state of the component to be detected under the gate closing state is abnormal, and based on the monitoring results under the gate opening state, the monitoring states of the gate corresponding to each component to be monitored are judged.

[0037] In a specific embodiment, the calculation process of obtaining the monitoring coefficients corresponding to each component to be monitored under the gate opening state is as follows: Normalize the monitoring information of each component to be monitored under the gate opening state and substitute it into the calculation formula.

[0038] Through the calculation formula Calculate the monitoring coefficient R corresponding to the b-th component to be monitored under the gate opening state b , where b is the number of each component to be monitored under the gate opening state, b = 1, 2,......, x, x is any integer greater than 2, η b is the coil voltage of the b-th component to be monitored under the gate opening state, β b is the control signal of the b-th component to be monitored under the gate opening state, θ b is the mechanical wear depth of the b-th component to be monitored under the gate opening state, κ b is the contact temperature of the b-th component to be monitored under the gate opening state, f1, f2, f3, and f4 are the weight factors of the set coil voltage, control signal, mechanical wear depth, and contact temperature respectively, 0 < f1 < 1, 0 < f2 < 1, 0 < f3 < 1, 0 < f4 < 1, and W is the set reference detection coefficient.

[0039] It should be noted that the monitoring coefficients corresponding to the opening states of the gates in each historical record are obtained from the database. By statistically analyzing the monitoring coefficients corresponding to the opening states of the gates in each historical record under normal conditions and calculating the average value of the statistically obtained monitoring coefficients, the average monitoring parameters are obtained, which are used as the reference monitoring coefficients.

[0040] It should also be noted that the weight factors of the coil voltage, control signal, mechanical wear depth, and contact temperature are obtained through the principal component analysis method. First, the information of the corresponding coil voltage, control signal, mechanical wear depth, and contact temperature is condensed, and then the corresponding variance explanation rate is obtained. Finally, the corresponding weights are obtained by dividing by the variance explanation rate.

[0041] Once again, it should be noted that information condensation refers to condensing multiple analysis items into several key summary indicators. The variance explanation rate refers to the contribution degree of each principal component or factor to the total variance, usually expressed as a percentage, indicating how much information of the original data is contained in the factor.

[0042] In a specific embodiment, the detection coefficients corresponding to each component to be detected in the gate closed state are obtained as follows: The detection information of each component to be detected in the gate closed state is standardized and substituted into the calculation formula.

[0043] Through the calculation formula The detection coefficient ξ corresponding to the c-th component to be detected in the gate closed state is calculated c , where c is the number of each component to be detected in the gate closed state, c = 1, 2,......, a, and a is any integer greater than 2. μ c is the inclination of the c-th component to be detected in the gate closed state, ψ c is the friction force of the c-th component to be detected in the gate closed state, is the noise of the c-th component to be detected in the gate closed state, μ′ is the set reference guide rail inclination, ψ′ is the set reference roller rotation speed jamming, is the set reference sensor control signal, j1, j2, and j3 are the weight factors of the inclination, friction force, and noise respectively, 0 < j1 < 1, 0 < j2 < 1, 0 < j3 < 1, and Y is the set reference detection coefficient.

[0044] It should be noted that the set reference inclination, reference friction, and reference noise are obtained from the safety use certificate corresponding to the gate. Before the gate is purchased, the seller will conduct performance tests on each component corresponding to the gate. Only when the performance of the gate components is qualified will it be sold. At the same time, the parameters when the performance test of the gate is qualified are recorded as reference data. The detection coefficients of each historical corresponding gate in the closed state are obtained from the database. By statistically analyzing the detection coefficients of each historical corresponding gate in the closed state in the normal state and calculating the average value of the statistically obtained detection coefficients, the average monitoring parameters are obtained, which are used as the reference detection coefficients.

[0045] It should also be noted that the weight factors of inclination, friction, and noise are obtained through the principal component analysis method. First, the information of the corresponding inclination, friction, and noise is concentrated, and then the corresponding variance explanation rate is obtained, and then divided by the variance explanation rate to obtain the corresponding weights.

[0046] The manual switch monitoring module of the gate is used to monitor and judge whether the state of the manual switch corresponding to the gate can be used normally.

[0047] It should be noted that comparing the apparent image of the current gate corresponding manual switch with the reference apparent image of the historical manual switch of the gate stored in the database means extracting the clean area from the apparent image of the current gate corresponding manual switch and comparing it with the clean area presented in the reference apparent image of the historical manual switch of the gate stored in the database; comparing the position image of the current gate corresponding manual switch with the reference position image of the historical manual switch of the gate stored in the database means extracting the chain position and rocker position from the position image of the current gate corresponding manual switch and comparing them with the chain position and rocker position presented in the reference position image of the historical manual switch of the gate stored in the database. The rocker position refers to vertical downward or parallel.

[0048] It should also be noted that the apparent images corresponding to the manual switch under each historical monitoring are obtained from the database, and the apparent images in the normal state are extracted from each apparent image and arranged according to the monitoring time. The apparent image closest to the current monitoring date is recorded as the reference apparent image for the current comparison. Similarly, the reference position image can be obtained.

[0049] In a specific embodiment, the judgment gate corresponds to whether the state of the manual switch can be used normally. The specific monitoring process is as follows: After completing the monitoring of each component to be monitored corresponding to the gate, the power supply corresponding to the current gate is cut off through remote control technology, and a basic image of the manual switch corresponding to the current gate is collected by using a camera. An apparent image and a position image corresponding to the manual switch of the current gate are extracted from the basic image, and a reference apparent image and a reference position image of the historical manual switch corresponding to the gate are obtained from the database.

[0050] The apparent image of the manual switch corresponding to the current gate is compared with the reference apparent image of the historical manual switch corresponding to the gate obtained from the database. At the same time, the position image of the manual switch corresponding to the current gate is compared with the reference position image of the historical manual switch corresponding to the gate obtained from the database. If the apparent image of the manual switch corresponding to the current gate is consistent with the reference apparent image of the historical manual switch corresponding to the gate obtained from the database, and the position image of the manual switch corresponding to the current gate is consistent with the reference position image of the historical manual switch corresponding to the gate obtained from the database, it is determined that the state of the manual switch corresponding to the gate is normal; otherwise, it is determined that the state of the manual switch corresponding to the gate is abnormal, so as to judge whether the state of the manual switch corresponding to the gate can be used normally.

[0051] The warning terminal is used to give a warning prompt when the phenomenon state of the gate is abnormal or the monitoring state of a certain component to be detected is abnormal during the application of the gate.

[0052] In the embodiment of the present invention, first, real-time monitoring is performed on the gate under the application of the warehouse, the corresponding state of the gate is analyzed, and each component to be monitored corresponding to the gate is screened out. Then, information monitoring corresponding to each component to be detected is performed, so as to judge the monitoring state of each component to be detected corresponding to the gate. At the same time, the state of the manual switch corresponding to the gate is monitored to judge whether it is abnormal, so as to realize the full-range online monitoring of the gate, so as to timely master the application state of the gate, quickly prevent the risks brought by the gate failure, solve the deficiencies in the current technology, and implement online monitoring of the gate, which can simplify the inconvenience of manual gate monitoring to a certain extent, reduce the burden of manual gate monitoring, effectively ensure the safe application of the gate, and at the same time, the efficient and real-time online gate information monitoring can effectively reduce the losses caused by the gate failure, improve the use efficiency and service life of the warehouse gate, and enable the warehouse to realize the safe application of the gate.

Those skilled in the art of the present technology make various modifications or supplements or use similar methods to replace the specific embodiments described, as long as they do not deviate from the concept of the invention or exceed the scope defined by this specification, they should all belong to the protection scope of the present invention.
