[0003] For example, a hazardous chemical storage safety management system with publication number CN107065798A includes a controller, a sensor electrically connected to the controller, the controller is connected to a control and adjustment device and an alarm device, the sensors are provided with a temperature sensor, a humidity sensor, a smoke sensor, and a toxic gas sensor; the adjustment device is provided with a humidifier, a dehumidifier, a heating device, a refrigeration device and a motor, and the motor drives the window to open and close; the alarm device is provided with a fire alarm and an anti-theft alarm; the controller controls the operation of the heating device or the refrigeration device according to the data of the temperature sensor, and the controller controls the humidifier and the dehumidifier according to the data of the humidity sensor; the controller controls the motor according to the concentration of the toxic gas sensor.

[0004] Although simple temperature and humidity can be adjusted automatically, other dangerous situations still require staff to patrol and monitor. Since the staff cannot monitor the storage area 24 hours a day, safety problems may occur during the period when the staff is not present and cannot be discovered in time. Different staff may have different understandings and masteries of safety standards, resulting in inconsistent standards implemented during the monitoring and management process, which affects the handling and resolution of safety issues. Summary of the invention

[0005] In order to improve the timeliness and accuracy of warehouse safety supervision, the present invention provides a warehouse safety supervision method and system.

[0006] In a first aspect, the present invention provides a storage safety supervision method, which adopts the following technical solution: A storage safety supervision method comprises the following steps: S1, divide the warehouse into multiple areas along the vertical direction according to the number and location of shelves; S2, real-time acquisition of various safety detection data based on safety detection equipment in each area; S3, judging whether each security detection data exceeds a safety range based on multiple preset security thresholds; S4, when it is judged that it exceeds the safety range, the safety detection data is mapped to the corresponding area, the danger type is determined according to the type of safety detection data, the danger level is determined according to the degree to which the safety detection data exceeds the safety range, the danger area, danger type and danger level are returned to the warehouse management end, and the danger type and danger level are warned on the warning light in the danger area.

[0007] By adopting the above technical solution, when the safety detection data exceeds the safety range, it is in a dangerous state, and the area to which the danger belongs, the type of danger and the level of danger are determined, so that the staff can be warned of the danger at the warehouse management end. When the staff goes to the warehouse for inspection and maintenance, the warning lights can provide warnings to the staff, so that the staff can eliminate the danger as soon as possible, thereby improving the timeliness and accuracy of warehouse safety supervision.

[0008] Optionally, the warehouse is divided into multiple areas along the vertical direction according to the number and location of shelves, specifically including: Determine the number of areas based on the number of shelves, and configure a unique shelf number for each area; Determine the boundary range of each area based on the shelf location; Associate the shelf number with its boundary range and store it in the database.

[0009] By adopting the above technical solution, each shelf area can be equipped with corresponding safety detection equipment according to the characteristics and storage requirements of the goods, which is convenient for staff to manage the goods and detect dangerous situations.

[0010] Optionally, before step S2, the method includes: Configure a unique identification ID for each safety detection device; Associating the identification IDs of the same type of safety detection equipment; Store the ID and associated relationship in the database.

[0011] By adopting the above technical solution, in the process of judging whether the security detection data exceeds the safety range, the identification ID of the same type of security detection equipment is associated, and the same type of security threshold is selected and judged, so as to distinguish and process all security detection data.

[0012] Optionally, determining the danger type according to the type of security detection data includes: determining the danger type according to the identification ID; Mapping security detection data to the region specifically includes: Establish a relationship mapping table between the safety detection equipment identification ID and the shelf number according to the installation location of the safety detection equipment; The identification ID of the security detection data is mapped to the area described therein.

[0014] Optionally, determining the danger level according to the degree to which the safety detection data exceeds the safety range includes: Setting different first danger thresholds and second danger thresholds for different danger types; When the safety detection data does not exceed the first danger threshold, it is judged as a slight danger H; When the safety detection data exceeds the first danger threshold but does not exceed the second danger threshold, it is judged as moderate danger W; When the safety detection data exceeds the second danger threshold, it is judged as severe danger Q; The relationship mapping table also stores the initial danger level N corresponding to the identification ID; The initial hazard level is updated according to the hazard level judgment result.

[0015] By adopting the above technical solution, the safety detection data exceeding the safety range is associated with the danger level according to the relationship mapping table, so as to facilitate subsequent warning operations.

[0016] Optionally, each zone is provided with two warning lights; In a warning light, when the safety detection data exceeds the safety range, a warning sound is issued to warn of danger, and different light colors are assigned to different danger levels, and different danger levels are warned by lights of different colors; In another warning light, different light colors are assigned to different types of danger, and different types of danger are warned by different light colors.

[0017] By adopting the above technical solution, the staff can judge the corresponding dangerous situation according to the warning light and then carry out corresponding maintenance work.

[0018] Optionally, when there are two or more hazard types and the hazard level of each hazard type is different: Randomly display all danger types in order; After each hazard type is displayed for a preset time, the next hazard type is switched to display; After the last hazard type is displayed within a preset time, the previous hazard type is switched to be displayed; During each preset time period, one warning light displays a hazard type and another warning light displays the hazard level corresponding to the hazard type.

[0019] By adopting the above technical solution, when there are multiple types of dangers with different levels, the two warning lights can simultaneously display the danger types and their corresponding danger levels within a preset time period. The staff can judge the safety issues based on the warning effects of the warning lights and solve them in a timely manner.

[0020] Optionally, issuing an alarm on the warehouse management end based on the danger area, danger type and danger level specifically includes: According to the collected shelf image information and warning light image information combined with the actual layout of the warehouse, a simulation model of the warehouse is established and displayed on the display screen of the warehouse management end; Set simulation numbers for the shelves in the simulation model and associate them with the shelf numbers; Based on the alarm conditions of the warning lights in the warehouse, the alarm conditions of the warning lights in the simulation model; Map the hazardous area to the shelf of the simulation model through simulation number; According to the received danger type and danger level, the sound and light alarm will be consistent with that in the warehouse.

[0021] By adopting the above technical solution and using the simulation model, the staff can intuitively see which shelf area in the warehouse has a danger, and obtain the danger type and level based on the warning lights, which helps the staff to detect and eliminate faults in a timely manner.

BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Figure 1 It is a flow chart of a warehouse safety supervision method according to an embodiment of the present invention.

[0026] Figure 2 It is a tabular diagram of a relationship mapping table in an embodiment of the present invention.

[0027] Figure 3 It is a schematic diagram of the structure of a warehouse safety supervision system according to an embodiment of the present invention. DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-3 The present invention is described in further detail.

[0029] Example 1 Reference Figure 1 A storage safety supervision method of this embodiment includes the following steps: S1, divide the warehouse into multiple areas along the vertical direction according to the number and location of shelves; Shelves are an important tool for warehouse modernization and efficiency improvement. Currently, when storing goods, items are usually classified and stored on different shelves according to purpose, type, value, storage requirements, etc. Each shelf may have some different safety hazards due to different goods. Therefore, the storage area can be divided into areas by shelves, which can reasonably layout the shelves, facilitate the storage and management of goods, and facilitate safety inspections in different areas.

[0030] S2, real-time acquisition of various safety detection data based on safety detection equipment in each area; In this embodiment, the safety detection equipment includes an inclination sensor, a temperature sensor, a smoke sensor, a water leakage rope, etc., which can obtain the shelf inclination data, temperature data, smoke concentration data and water flow data in the warehouse accordingly. The safety detection equipment can be increased or decreased according to the storage needs; S3, judging whether each security detection data exceeds a safety range based on multiple preset security thresholds; S4, when it is judged that it exceeds the safety range, the safety detection data is mapped to the corresponding area, the danger type is determined according to the type of safety detection data, the danger level is determined according to the degree to which the safety detection data exceeds the safety range, an alarm is issued at the warehouse management end based on the danger area, danger type and danger level, and a warning of the danger type and danger level is given on the warning light in the danger area.

[0031] According to the number and location of shelves, the warehouse is divided into multiple areas along the vertical direction, including: Determine the number of areas according to the number of shelves, and configure a unique shelf number for each area, such as H001, H002, ... H00n; Determine the boundary range of each area according to the shelf position; select a fixed base point in the warehouse, establish a three-dimensional coordinate system, and accurately measure the position of each shelf along the length direction of the warehouse as the X axis, the width direction as the Y axis, and the height direction as the Z axis. Record the coordinates of each shelf in the coordinate system. Since there is a distance between each shelf, the range around each shelf is also included in the area to which the shelf belongs. There is no overlap between each area, and all areas constitute the entire area of ​​the warehouse. At this time, the minimum coordinate value constitutes the lower left corner (or lower front) boundary of the area, and the maximum coordinate value constitutes the upper right corner (or upper back) boundary of the area.

[0032] The shelf number and its boundary range are associated and stored in the database. A data table is created for each shelf number and its corresponding boundary range, and the data table is stored in the database.

[0033] Before step S2, the following steps are included: Configure a unique identification ID for each safety detection device; Associating the identification IDs of the same type of safety detection equipment; Store the ID and associated relationship in the database.

[0034] For example, all inclination sensors are configured as M1, M2...Mn, and temperature sensors are configured as T1, T2...Tn, and so on. The same type of safety monitoring equipment has the same first letter.

[0035] Determining the danger type according to the type of safety detection data includes: determining the danger type according to the identification ID; Mapping security detection data to the region specifically includes: Establish a relationship mapping table between the safety detection equipment identification ID and the shelf number according to the installation location of the safety detection equipment; The corresponding shelf number is obtained in the relationship mapping table according to the identification ID of the safety detection data to determine the area to which the safety detection data belongs.

[0036] Reference Figure 2 For example, the type of danger can be determined by the first letter in the identification ID. After installing the safety detection equipment, the staff obtains that M1, M2, and T1 are located in area H001 based on the installation location of the safety detection equipment, and establishes a mapping relationship between M1, installation location, and H001, a mapping relationship between M2, installation location, and H001, and a mapping relationship between T1, installation location, and H001. All mapping relationships constitute a mapping table.

[0037] Determining the danger level based on the degree to which the safety test data exceeds the safety range includes: Setting different first danger thresholds and second danger thresholds for different danger types; When the safety detection data does not exceed the first danger threshold, it is judged as a slight danger H; When the safety detection data exceeds the first danger threshold but does not exceed the second danger threshold, it is judged as moderate danger W; When the safety detection data exceeds the second danger threshold, it is judged as severe danger Q; The relationship mapping table also stores the initial danger level N corresponding to the identification ID; N represents that there is no danger; The initial hazard level is updated according to the hazard level judgment result.

[0038] Reference Figure 2 In this embodiment, a mapping table can be established between the safety detection data identification ID and the shelf number and the danger level. For example, M1, M2, and T1 are located in area H001, M3 and T2 are located in area H002, M1 is moderately dangerous, M2 is moderately dangerous, T1 is highly dangerous, and M3 and T2 are not dangerous. A mapping relationship is established between M1, H001, and W, a mapping relationship is established between M2, H001, and W, a mapping relationship is established between T1, H001, and Q, a mapping relationship is established between M3, H002, and N, and a mapping relationship is established between T2, H002, and N. All mapping relationships constitute a mapping table.

[0039] Each area is equipped with two warning lights; In a warning light, when the safety detection data exceeds the safety range, a warning sound is issued to warn of danger, and different light colors are assigned to different danger levels, and different danger levels are warned by lights of different colors; in this embodiment, green is assigned to warn of mild danger, yellow is assigned to warn of moderate danger, and red is assigned to warn of severe danger; In another warning light, different light colors are assigned to different types of danger, and different types of danger are warned by different light colors. This warning light uses a warning light with more colors so that each color corresponds to a different safety detection device. When the number of warning light colors is less than the number of safety detection devices, warning processing can be carried out by adding warning lights or cooperating with other warning rules.

[0040] When there are two or more hazard types and the hazard level of each hazard type is different: All hazard types are randomly displayed in order. Since the time when the staff enters the warehouse is uncertain, the hazard type that the staff sees first is also uncertain. Therefore, there is no requirement for the order in which the hazard types are displayed. They can be sorted according to the habits of the staff. After each hazard type is displayed within the preset time, the next hazard type is switched to be displayed; the preset time is usually set to within 30 seconds to avoid the warning time of each hazard type being too long, which makes it difficult for staff to notice the hazard type behind.

[0041] After the last hazard type is displayed within a preset time, the previous hazard type is switched to display; before the hazard is eliminated, all hazard types are displayed in a loop to facilitate staff to detect hazards in a timely manner.

[0042] During each preset time period, one warning light displays a danger type, and another warning light displays the danger level corresponding to the danger type, thereby realizing the simultaneous display of the danger type and danger level.

[0043] In step S4, issuing an alarm on the warehouse management end based on the danger area, danger type and danger level specifically includes: According to the collected shelf image information and warning light image information combined with the actual layout of the warehouse, a simulation model of the warehouse is established and displayed on the display screen of the warehouse management end; according to the actual warehouse situation, it can be selected whether to add a safety detection equipment model, etc. Set simulation numbers for the shelves in the simulation model and associate them with the shelf numbers; refer to Figure 2 The simulation numbers are S001, S002, etc., which correspond one to one with the shelf numbers H001, H002, etc.

[0044] Based on the alarm conditions of the warning lights in the warehouse, the alarm conditions of the warning lights in the simulation model; Map the hazardous area to the shelf of the simulation model through simulation number; According to the received danger type and danger level, the sound and light alarm is consistent with that in the warehouse. The shelf is first located in the dangerous area, and then the corresponding warning light alarm is sounded at the corresponding shelf position. The staff can view the alarm information consistent with that in the warehouse at the warehouse management end, which is conducive to the warehouse staff to find danger in time and respond in time.

[0045] Example 2 Reference Figure 3 The difference between this embodiment and embodiment 1 is that this embodiment provides a storage safety supervision system, including: The data acquisition module is set at the storage end, including multiple safety detection devices, and the storage safety detection data is collected in real time through the safety detection devices; in this embodiment, the installation of the safety detection equipment is also carried out around the shelf, and the safety detection equipment includes an inclination sensor, a temperature sensor, a smoke sensor, and a leaking rope, etc. Among them, two inclination sensors are set as a group, respectively, at two diagonally opposite corners of the shelf in the horizontal direction, to increase the accuracy of the shelf tilt detection; the smoke sensor is set vertically above the center of the shelf and fixed to the top of the warehouse, so that the smoke sensor can accurately detect the smoke situation in each area, which is conducive to the staff to find the danger point according to the danger level of the smoke concentration, etc., so that the safety detection in each area is more accurate, and the accuracy of the safety detection in the entire warehouse is enhanced.

[0046] The host module is arranged at the warehouse management end, connected to the data acquisition module, receives the safety detection data, divides the warehouse into multiple areas along the vertical direction according to the number and position of the shelves, judges whether each safety detection data exceeds the safety range based on multiple preset safety thresholds, and maps the safety detection data to the corresponding area when it is judged to exceed the safety range, determines the danger type according to the type of the safety detection data, determines the danger level according to the degree to which the safety detection data exceeds the safety range, and returns the danger area, danger type and danger level to the warehouse management end; The first warning module is arranged at the storage end, includes a plurality of warning lights, is connected to the host module, and warns of the type and level of danger on the warning lights of the danger area; The second warning module is set at the warehouse management end and connected to the host module to warn the dangerous area, dangerous type and dangerous level as dangerous information. The second warning module specifically includes: a warehouse simulation model, which is established based on the collected shelf image information and warning light image information combined with the actual layout of the warehouse, and is displayed on the display screen of the warehouse management end.
