Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

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

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1 As shown, a gate status online monitoring system includes: a gate real-time monitoring module, a gate component monitoring unit and an early warning terminal.

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

[0020] The gate real-time monitoring module is used to perform real-time monitoring on the gates under warehouse application and analyze the status of the gates when in use.

[0021] In a specific embodiment, the analysis of the phenomenal state of the gate when it is used, the specific analysis process is as follows: based on the camera installed at the gate position, the opening image and the closing image of the warehouse gate corresponding to each time period when it is used are obtained in real time, and the corresponding performance of the gate is obtained from the opening image and the closing image of the gate corresponding to each time period respectively. If the opening image shows that the gate falls instantly in a certain period after opening, it is determined that the gate state is abnormal, and information is sent to the gate component monitoring unit to automatically perform the gate component detection. When the closing image shows that the gate cannot complete the closing task at one time during the closing process of a certain period, the bottom of the gate is redundant after closing, or it is extracted from the closing image that there is a foreign object at the bottom of the gate, but the gate does not activate the foreign object alarm and continues to perform the closing task, and the performance of being unable to close appears, it is determined that the gate state is abnormal, and information is sent to the gate component monitoring unit to automatically perform the gate component detection. The above analysis is combined to obtain the corresponding abnormal states of the gate, and the state of the gate when it is used is analyzed.

[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 the components to be monitored corresponding to the gate according to the reference matching results of the historical abnormal phenomena corresponding to the gate.

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

[0025] It should also be noted that each abnormal component set refers to the abnormal state detection 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, and so on, the abnormal component sets corresponding to each historical abnormal state are summarized. For example, the gate is monitored for 10 times. When the gate drops instantly or automatically in all 10 monitorings, and 8 analysis results are gate relay failures, it means that after the gate drops instantly or automatically, the relay component needs to be monitored accordingly.

[0026] In a specific embodiment, the screening obtains the components to be monitored corresponding to the gate, and the specific analysis process is as follows: compare the abnormal states corresponding to the gate with the sets of abnormal components corresponding to the historical abnormal states stored in the database. If a certain abnormal state corresponding to the gate is in a certain abnormal component set corresponding to a certain historical abnormal state stored in the database, then the abnormal component is used as the component to be monitored when the gate corresponds to the abnormal state, and then the components to be monitored are obtained by analogy and comparison, so as to screen out the components to be monitored corresponding to the gate.

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

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

[0029] In a specific embodiment, the monitoring information of each component to be detected corresponding to the gate is obtained, and the specific acquisition process is as follows: based on the state characteristics presented in the open image and closed image of the gate in each time period, the acquisition process is further divided into the monitoring of each component to be monitored when the gate is open and the detection of each component to be monitored when the gate is closed.

[0030] Each component to be detected is monitored when the gate is open, and an allowable value of a reference monitoring parameter corresponding to each component to be detected is set. By automatically turning on the sensor at the position of each component to be detected, the monitoring information of each component to be detected in the open state is obtained, wherein the monitoring information includes coil voltage, control signal, mechanical wear depth and contact temperature. When the value of a monitoring parameter monitored by the sensor corresponding to a component to be detected exceeds the set allowable value of the reference monitoring parameter, the exceeded parameter corresponding to the component to be detected is recorded, so as to obtain the monitoring information corresponding to each component to be detected in the gate open state.

[0031] In a specific embodiment, the detection information corresponding to each component to be detected when the gate is closed is obtained, and the specific acquisition process is as follows: set a reference detection parameter reference value corresponding to each component to be detected when the gate is closed, and automatically turn on the sensor at the position of each component to be detected, the sensor includes a displacement sensor, a force sensor and a vibration sensor, so as to obtain the detection information of each component to be detected in the closed state, wherein the detection information includes inclination, friction and noise. When the detection parameter value detected by the sensor corresponding to a component to be detected exceeds the set detection parameter reference value, the exceeded parameter corresponding to the component to be detected is recorded, and the monitoring information corresponding to each component to be detected when the gate is open is integrated to obtain the monitoring information of each component to be detected corresponding to the gate.

[0032] The gate component analysis module is used to determine the monitoring status of each to-be-detected component 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 open, the demand monitoring judgment features corresponding to each component to be monitored in the gate open state are extracted, and the extracted demand monitoring judgment features corresponding to each component to be monitored in the gate open state are compared with the feature sets corresponding to each prediction model. If the extracted demand monitoring judgment features corresponding to a component to be monitored in the gate open state are within the feature set corresponding to a prediction model, the prediction model is used as the prediction model for judging the corresponding monitoring status of each component to be monitored in the gate open state. Similarly, the prediction model for the corresponding monitoring status of each component to be monitored in the gate 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 gate corresponds to the monitoring status of each component to be monitored, and the specific judgment process is as follows: respectively extracting the monitoring information of each component to be monitored when the gate is open and the detection information of each component to be monitored when the gate is closed.

[0035] The monitoring information is input into the prediction model to obtain the monitoring coefficient corresponding to each component to be monitored when the gate is open. When the predicted monitoring result corresponding to a component to be monitored when the gate is open is 0, it is determined that the state of the component to be monitored when the gate is open is normal. If the predicted monitoring result corresponding to a component to be monitored when the gate is open is 1, it is determined that the state of the component to be monitored when the gate is open is abnormal. Similarly, the monitoring state corresponding to each component to be monitored when the gate is open is obtained.

[0036] In a specific embodiment, the monitoring status of each component to be monitored when the gate is closed is determined, and the specific judgment process is as follows: the detection information is input into the prediction model, and then the detection coefficient corresponding to each component to be monitored when the gate is closed is obtained. When the output result corresponding to the prediction of a component to be monitored when the gate is closed is 0, it is determined that the state of the component to be monitored when the gate is closed is normal. If the output result corresponding to the prediction of a component to be monitored when the gate is closed is 1, it is determined that the state of the component to be monitored when the gate is closed is abnormal, and the monitoring results when the gate is open are combined to determine the monitoring status of each component to be monitored corresponding to the gate.

[0037] In a specific embodiment, the monitoring coefficient corresponding to each component to be monitored when the gate is open is calculated, and the specific calculation process is as follows: the monitoring information of each component to be monitored when the gate is open is normalized and substituted into the calculation formula.

[0038] By calculating the formula , calculate the gate open state The monitoring coefficient corresponding to the components to be monitored , is the number of each component to be tested when the gate is open. , is any integer greater than 2, The gate is open. The coil voltage of the component to be monitored, The gate is open. The control signal of the component to be monitored, The gate is open. The mechanical wear depth of the component to be monitored, The gate is open. The contact temperature of the component to be monitored, , , and They are the weight factors of the set coil voltage, control signal, mechanical wear depth and contact temperature. , , , , is the set reference detection coefficient.

[0039] It should be noted that the monitoring coefficients of each historical corresponding gate opening state are obtained from the database, and the monitoring coefficients of each historical corresponding gate opening state in the normal state are statistically analyzed, and the average value of the statistical monitoring coefficients is calculated to obtain the average monitoring parameter, which is used as the reference monitoring coefficient.

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

[0041] It is important to note again that information condensation refers to condensing multiple analysis items into several key summary indicators, and the variance explanation rate refers to the contribution of each principal component or factor to the overall variance, usually expressed as a percentage, indicating how much information the factor contains about the original data.

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

[0043] By calculating the formula , the corresponding The detection coefficient of the components to be detected , is the number of each component to be tested when the gate is closed. , is any integer greater than 2, The gate is closed. The inclination of the component to be monitored, The gate is closed. The friction of the component to be monitored, The gate is closed. The noise of the components to be monitored, is the set reference rail inclination, The reference roller speed is set to freeze. is the set reference sensor control signal, , and are the weight factors of the set inclination, friction and noise respectively. , , , 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 certificate corresponding to the gate. Before the gate is bought, the seller will perform performance tests on the corresponding components of the gate. The gate will be sold only when the performance of the corresponding components is qualified. At the same time, the parameters of the gate when the performance test is qualified are also recorded as reference data, and the detection coefficients of each historical gate closing state are obtained from the database. The detection coefficients of each historical gate closing state in the normal state are statistically analyzed, and the statistically obtained detection coefficients are averaged to obtain the average monitoring parameters, which are used as the reference detection coefficients.

[0045] It should also be noted that the weight factors of the inclination, friction and noise are obtained through principal component analysis. The information of the corresponding inclination, friction and noise is first condensed, and then the corresponding variance explanation rate is obtained, and then divided by the variance explanation rate to get the corresponding weight.

[0046] The gate manual switch monitoring module is used to monitor and determine 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 manual switch corresponding to the current gate with the reference apparent image of the historical manual switch corresponding to the gate stored in the database means extracting the clean area from the apparent image of the manual switch corresponding to the current gate and comparing it with the clean area presented in the reference apparent image of the historical manual switch corresponding to the gate stored in the database; comparing the position image of the manual switch corresponding to the current gate with the reference position image of the historical manual switch corresponding to the gate stored in the database means extracting the chain position and the rocker position from the position image of the manual switch corresponding to the current gate and comparing them with the chain position and the rocker position presented in the reference position image of the historical manual switch corresponding to the gate stored in the database, and the rocker position refers to vertically downward or parallel.

[0048] It should also be noted that the apparent images corresponding to the manual switches under each historical monitoring are obtained from the database, and the apparent images in 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 current comparison. Similarly, the reference position image can be obtained.

[0049] In a specific embodiment, the determination of whether the state of the manual switch corresponding to the gate can be used normally is carried out through the following specific monitoring process: after the monitoring of the components to be monitored corresponding to the gate is completed, the power supply corresponding to the current gate is cut off through remote control technology, and the basic image of the manual switch corresponding to the current gate is collected by a camera, and the appearance image and position image corresponding to the manual switch of the current gate are extracted from the basic image, and the reference appearance image and 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 in 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 in 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 in 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 in the database, then 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 early warning terminal is used to issue an early warning prompt when the gate is in an abnormal state during use or when the monitoring state of a component to be detected is abnormal.

[0052] The embodiment of the present invention first performs real-time monitoring on the gates under the warehouse application, analyzes the corresponding status of the gates, and screens out the corresponding components to be monitored of the gates, and then performs information monitoring corresponding to the components to be detected, so as to judge the monitoring status of the corresponding components to be detected of the gates, and at the same time monitors the status of the manual switches corresponding to the gates to judge whether they are abnormal, so as to achieve all-round online monitoring of the gates, so as to timely grasp the application status of the gates, and quickly prevent the risks caused by gate failures, solve the shortcomings of the current technology, and implement online monitoring of the gates, which can simplify the inconvenience of manual gate monitoring to a certain extent, reduce the burden of manual gate monitoring, and effectively ensure the safe application of the gates. At the same time, efficient and real-time online gate information monitoring can effectively reduce the losses caused by gate failures, improve the corresponding use efficiency and life of warehouse gates, and enable warehouses to achieve safe application of gates.
