The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.

[0013] The present application provides a three-dimensional visualization monitoring method, controller, three-dimensional visualization monitoring system and computer readable storage medium for cold storage, relating to the technical field of intelligent management of cold storage. The method comprises: acquiring device state data and cold storage environment data in a physical cold storage in real time; binding and associating the device state data and the cold storage environment data with a first three-dimensional digital model constructed in advance to obtain a second three-dimensional digital model; monitoring the cold storage environment data and the device state data for abnormalities, and in the case that the obtained cold storage monitoring condition indicates that the physical cold storage has an abnormal state, determining a rendering object and a corresponding object rendering mode according to the cold storage monitoring condition; performing color rendering alarm processing on the second three-dimensional digital model according to the rendering object and the corresponding rendering mode to obtain a cold storage three-dimensional scene; and visualizing and displaying the cold storage three-dimensional scene on a monitoring interaction interface; wherein the cold storage three-dimensional scene displays abnormal alarm information. The method can reduce the management difficulty and cost of the cold storage and improve the management efficiency of the cold storage.

[0014] The embodiments of the present application will be further described below with reference to the accompanying drawings.

[0015] As shown in Figure 1 The three-dimensional visualization monitoring system 1000 comprises: a controller 100, a monitoring terminal 200 in communication connection with the controller 100, a data acquisition module 400 deployed in a physical cold storage, and an interactive display device 300 electrically connected with the controller 100; wherein the data acquisition module 400 comprises a plurality of sensor devices; each sensor device is deployed in the physical cold storage according to a preset spatial planning mode.

[0016] It can be understood that the sensor devices include but are not limited to temperature sensors, humidity sensors, current sensors, door magnetic switches and the like. Therefore, the present application does not specifically limit the types of sensor devices in the physical cold storage.

[0017] Specifically, the sensor device is used to collect device state data and cold storage environment data in the physical cold storage in real time, to provide reliable data reference for abnormal monitoring of the physical cold storage and subsequent construction of a cold storage three-dimensional scene.

[0018] Further illustrate the setting mode and space planning mode of the sensor device. The deployment position and quantity of the sensor device are determined according to the effective detection range and the space structure and air flow organization of the cold storage, and the specific strategies are as follows: first, basic grid layout: taking the nominal effective detection radius of various sensor devices (especially temperature and humidity sensors) as the benchmark, the three-dimensional space of the cold storage is divided into grids; the spacing of the sensor devices is ensured to ensure that their effective detection ranges can be connected to each other to form a continuous monitoring network with no blind area. Second, redundant coverage in key areas: in the key areas where the temperature is easy to fluctuate and the risk is high (such as the inner side of the cold storage door, the vicinity of the air supply / return port, the weak structure of the building, and the high-value goods storage area), the spacing of the sensor devices is encrypted beyond the basic grid to achieve overlapping coverage of the detection range of the sensor devices, so as to improve the monitoring reliability and data accuracy of these areas. Third, device correlation positioning: the position of the sensor device for detecting the state of the device in the cold storage is determined by its function, and is fixed on the corresponding physical device (such as the current sensor is connected to the power supply circuit of the unit, and the door magnetic switch is installed on the door frame and the door body).

[0019] Specifically, as shown in Figure 2 The controller 100 includes: a three-dimensional digital twin model construction module 101, a real-time data driving and mapping module 102, and a visual rendering and interaction module 103. Specifically, the three-dimensional digital twin model construction module 101 is used to create and render a first three-dimensional digital model of the physical cold storage, wherein the first three-dimensional digital model is a high-fidelity three-dimensional virtual model. The real-time data driving and mapping module 102 is used to receive the device state data and cold storage environment data in the physical cold storage collected by the data acquisition module 400 in real time, and bind and drive the real-time collected data to the corresponding virtual entity in the three-dimensional digital model, so that the state of the three-dimensional digital model is synchronized with the physical cold storage. The visual rendering and interaction module 103 is used to realize three-dimensional panoramic display, that is, to render the entire cold storage environment in a three-dimensional panoramic manner, so that the user can operate the three-dimensional digital model, such as freely rotating, zooming, and translating the viewing angle; real-time data superimposed display: binding and driving the real-time collected data to the corresponding virtual entity in the three-dimensional digital model, so as to superimposed display; color temperature rendering alarm: that is, according to the preset threshold information, the color gradient (for example, blue to red representing temperature from low to high) is used to render the overall color of the target rendering area in the three-dimensional digital model, and the abnormal area (such as temperature exceeding the standard) is highlighted in a prominent color (such as red), to realize abnormal "one-key positioning".

[0020] The interactive display device 300 is used to provide a cloud or local monitoring interaction interface, and the monitoring interaction interface is used for visualizing display of a cold storage three-dimensional scene. Specifically, a user can perform query operation on the cold storage three-dimensional scene of the monitoring interaction interface, for example, when the user hovers or clicks a device model of a certain virtual sensor or physical device in the model, real-time data stream is dynamically displayed in the form of an information box. The user can also operate the cold storage three-dimensional scene itself, for example, the user can operate the three-dimensional digital model to freely rotate, zoom, and translate the view angle.

[0021] Specifically, when the three-dimensional visual monitoring system 1000 is developed, a WebGL technology (such as a Three.js framework) is used to develop a visual rendering engine on a web side. A data receiving, processing and forwarding service is developed on a back end by using a Java / Python language, and a time series database (such as an InfluxDB) is used to store sensor data.

[0022] The three-dimensional visual monitoring system 1000 realizes data integration by receiving data from an Internet of Things platform through an MQTT or HTTP protocol. By analyzing data packets, and according to a device ID, a corresponding virtual object in a three-dimensional digital model is matched, and a device state attribute is updated.

[0023] The three-dimensional visual monitoring system 1000 can realize an interaction function, an alarm function and a data display function. The interaction function refers to that a user logs in a monitoring platform through a browser, and operates a three-dimensional digital model through a mouse and a keyboard. The alarm function refers to that an alarm rule is set in a database or a front end. For example, when an environmental temperature value is greater than -15℃, a region where the sensor is located is rendered as red and an alarm box is popped up. The data display function refers to that when a specific device (such as a refrigeration unit) is clicked, a detailed data panel is popped up on one side of the interface, and deep information such as a historical curve and a running parameter of the device is displayed.

[0024] According to the three-dimensional visual monitoring system 1000 provided in the embodiments of the present application, the controller 100, the data acquisition module 400 and the interactive display device 300 cooperate with each other, so that the controller 100 performs the three-dimensional visual monitoring method for the cold storage provided in the embodiments of the present application, the management difficulty and cost of the cold storage are reduced, and the management efficiency of the cold storage is improved.

[0025] Those skilled in the art can understand that the system structure shown in the figure does not constitute a limitation on the embodiments of the present application, and can include more or fewer components than the figure, or combine certain components, or different component arrangements.

[0026] The system embodiments described above are merely illustrative, wherein the units described as separate components can or can not be physically separated, i.e., can be located in one place, or can be distributed to multiple network units. Part or all of the modules can be selected according to actual needs to achieve the purpose of the embodiment.

[0027] Those skilled in the art can understand that the system architecture and application scenarios described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, with the evolution of system architecture and the appearance of new application scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0028] Based on the above system structure, the following embodiments of the three-dimensional visual monitoring method for cold storage of the present application are proposed.

[0029] In a first aspect, as Figure 3 indicated, the three-dimensional visual monitoring method for cold storage can be applied to the system framework as Figure 1 indicated, the three-dimensional visual monitoring method for cold storage can include but is not limited to steps S100 to S500.

[0030] It can be understood that before step S100 is performed, the three-dimensional visual monitoring method for cold storage further includes: performing model construction processing based on an actual physical cold storage to obtain a first three-dimensional digital model of the pre-constructed physical cold storage. The first three-dimensional digital model is constructed to provide a model basis for subsequent establishment of a cold storage three-dimensional scene.

[0031] Specifically, in the model construction processing process, a 3D modeling software (such as 3Ds Max, Blender) or through laser scanning point cloud data is used to create a three-dimensional model corresponding to the physical cold storage 1:1, and the format is glTF or OBJ. The first three-dimensional digital model needs to be constructed in layers, and the first three-dimensional digital model includes a building structure layer, a physical device layer, and a sensor device layer. The building structure layer includes: the building body, shelves, and partition corresponding building structure models (such as walls) of the physical cold storage; the physical device layer includes: chiller units, evaporators, cold storage doors, and other device models; and the sensor device layer includes: sensor models corresponding to each sensor device.

[0032] Specifically, in the process of constructing the first three-dimensional digital model, digital mapping is realized; that is, when constructing the three-dimensional digital twin model, the position of each sensor model is accurately corresponding to the real space coordinates of its sensor device, and the effective detection range of the sensor device can be visualized in the model, providing an intuitive basis for analyzing the influence area of the alarm.

[0033] Specifically, after the digital mapping is implemented, the virtual position information of all sensor devices and physical devices in the first three-dimensional digital model is labeled.

[0034] Step S100: Real-time acquisition of device state data and cold storage environment data in the physical cold storage.

[0035] It should be noted that a plurality of sensor devices are deployed in the actual physical cold storage, and the sensor devices preferably access in a wireless communication mode (such as LoRa, NB-IoT). The controller can acquire the cold storage environment data and the device state data in real time through the sensor devices. Specifically, the cold storage environment data includes but is not limited to the environmental temperature value, the environmental humidity value, and the like; and the device state data includes but is not limited to the refrigeration unit power, the door switch state, the fan speed, and the like.

[0036] Step S200: Binding and associating the device state data and the cold storage environment data with the pre-constructed first three-dimensional digital model to obtain a second three-dimensional digital model; wherein the physical cold storage includes physical devices, and the first three-dimensional digital model includes device models of the physical devices.

[0037] It can be understood that the second three-dimensional digital model includes: a building structure model, a device model obtained by virtually mapping the physical devices, a sensor model obtained by virtually mapping the sensor devices, and the device state data and the cold storage environment data bound and associated with the virtual models.

[0038] Through step S200, the present application associates and maps the real-time received device state data and cold storage environment data with the corresponding virtual entities (i.e., sensor models and device models) in the first three-dimensional digital model, so as to facilitate subsequent real-time monitoring of the situation in the cold storage in the cold storage three-dimensional scene.

[0039] Step S300: Abnormal monitoring of the cold storage environment data and the device state data, and in the case where the obtained cold storage monitoring situation indicates that the physical cold storage has an abnormal state, determining a rendering object and a corresponding object rendering mode according to the cold storage monitoring situation; wherein the rendering object only includes different types of target rendering areas in the second three-dimensional digital model; or the rendering object includes the target rendering areas and the device models corresponding to the abnormal physical devices; and the different types of target rendering areas include: a low-temperature normal area, a standard normal area, a pre-warning area, and an alarm area.

[0040] Specifically, the abnormal state of the physical cold storage refers to that the environmental temperature value of a local area exceeds the allowed maximum temperature value, or the device state data of certain physical devices appears abnormal (such as excessively large running current, etc.).

[0041] According to some embodiments of the present application, step S300 is further illustrated, wherein the abnormality monitoring is performed on the cold storage environment data and the equipment state data, and in a case where the obtained cold storage monitoring condition indicates that the physical cold storage is in an abnormal state, the rendering object and the corresponding object rendering mode are determined according to the cold storage monitoring condition, including but not limited to steps S310 to S320.

[0042] Step S310: performing data comparison on the cold storage environment data and the preset threshold information to obtain a comparison result, and performing data abnormality identification on the equipment state data to determine the equipment condition.

[0043] In this step, the cold storage monitoring condition includes: the equipment condition, and the comparison result between the cold storage environment data and the preset threshold information.

[0044] Specifically, the cold storage environment data includes: an environment temperature value; and the preset threshold information includes a first temperature threshold, a second temperature threshold greater than the first temperature threshold, and a third temperature threshold greater than the second temperature threshold.

[0045] Through step S310, the comparison result between the equipment condition, the cold storage environment data and the preset threshold information can be determined, so as to facilitate subsequent determination of the rendering object and the corresponding object rendering mode.

[0046] Step S320: in a case where the cold storage monitoring condition indicates that the physical cold storage is in an abnormal state, the rendering object and the corresponding object rendering mode are determined according to the comparison result and the equipment condition.

[0047] According to some embodiments of the present application, step S320 is further illustrated, wherein the rendering object and the corresponding object rendering mode are determined according to the comparison result and the equipment condition, including but not limited to steps S321 to S323.

[0048] Step S321: determining different types of target rendering areas in the second three-dimensional digital model according to the comparison result, and determining the corresponding environment rendering mode of each target rendering area.

[0049] In this step, specifically, the different types of target rendering areas include: a low-temperature normal area, a standard normal area, a pre-warning area and an alarm area.

[0050] According to some embodiments of the present application, step S321 includes but is not limited to steps S3211 to S3214.

[0051] Step S3211: in a case where the environment temperature value is less than or equal to the first temperature threshold, the corresponding environment area is determined as the low-temperature normal area, and the corresponding environment rendering mode is determined as the low-temperature normal rendering mode.

[0052] In an embodiment, the first temperature threshold is -22°C. The first temperature threshold can also be set according to the actual size of the cold storage and preservation requirements, and the application does not specifically limit the value of the first temperature threshold.

[0053] It can be understood that the environmental temperature value is collected by a sensor device, and the sensor device has a certain monitoring range. In the case that the environmental temperature value is less than or equal to the first temperature threshold, the environmental area in the monitoring range determined by the sensor device is determined as a low-temperature normal area.

[0054] It can be understood that no alarm display is needed for the low-temperature normal area. In an embodiment, the low-temperature normal rendering mode is to render the low-temperature normal area as dark blue.

[0055] Step S3212: In the case that the environmental temperature value is greater than the first temperature threshold and less than or equal to the second temperature threshold, the corresponding environmental area is determined as a standard normal area, and the corresponding environmental rendering mode is determined as a standard normal rendering mode.

[0056] In an embodiment, the second temperature threshold is -18°C. The second temperature threshold can also be set according to the actual size of the cold storage and preservation requirements, and the application does not specifically limit the value of the second temperature threshold.

[0057] It can be understood that no alarm display is needed for the standard normal area. In an embodiment, the standard normal rendering mode is to render the standard normal area as light blue or green.

[0058] Step S3213: In the case that the environmental temperature value is greater than the second temperature threshold and less than or equal to the third temperature threshold, the corresponding environmental area is determined as a pre-warning area, and the corresponding environmental rendering mode is determined as a pre-warning rendering mode.

[0059] In an embodiment, the third temperature threshold is -15°C. The third temperature threshold can also be set according to the actual size of the cold storage and preservation requirements, and the application does not specifically limit the value of the third temperature threshold.

[0060] It can be understood that alarm display is needed for the pre-warning area. In an embodiment, the pre-warning rendering mode is to render the standard normal area as orange or yellow.

[0061] Step S3214: In the case that the environmental temperature value is greater than the third temperature threshold, the corresponding environmental area is determined as an alarm area, and the corresponding environmental rendering mode is determined as an alarm rendering mode.

[0062] In this step, it can be understood that alarm display is needed for the alarm area. In an embodiment, the alarm rendering mode is to render the alarm area as red and flashing.

[0063] The target rendering area and the corresponding environment rendering mode are determined through steps S3211-S3214, thereby providing a reference for subsequent color rendering alarm processing.

[0064] Step S322: In the case where the device condition indicates that all physical devices are normal, it is determined that the rendering object only includes different types of target rendering areas.

[0065] It can be understood that, in the case where the device condition indicates that all physical devices are normal, it is indicated that the device model corresponding to the physical device does not need to be alarm displayed in the second three-dimensional digital model, and therefore the rendering object involved in subsequent color rendering alarm processing only includes different types of target rendering areas.

[0066] Step S323: In the case where the device condition indicates that there is an abnormal physical device, it is determined that the rendering object includes the target rendering area and the device model corresponding to the abnormal physical device, and the corresponding device rendering mode is determined.

[0067] It can be understood that, in the case where the device condition indicates that there is an abnormal physical device, the device model corresponding to the abnormal physical device needs to be alarm displayed in the second three-dimensional digital model at this time, and therefore the rendering object involved in subsequent color rendering alarm processing includes the target rendering area and the device model corresponding to the abnormal physical device.

[0068] Specifically, the corresponding device rendering mode means that the device model corresponding to the abnormal physical device is rendered as red and flashing.

[0069] Through steps S321-S322, the rendering object and the corresponding object rendering mode are determined, thereby providing a reliable reference for subsequent color rendering alarm processing.

[0070] Step S400: The second three-dimensional digital model is subjected to color rendering alarm processing according to the rendering object and the corresponding rendering mode, thereby obtaining a cold storage three-dimensional scene.

[0071] It can be understood that the rendering object can only include different types of target rendering areas, or the rendering object includes the target rendering area and the device model corresponding to the abnormal physical device.

[0072] Two parallel embodiments of step S400 are further described as follows.

[0073] According to some embodiments of the present application, Embodiment One: Step S400 includes but is not limited to step S410.

[0074] Step S410: In the case that the rendering object only includes different types of target rendering areas, the first color rendering processing is performed on each target rendering area of the second three-dimensional digital model according to the corresponding environment rendering mode, and a cold storage three-dimensional scene is obtained.

[0075] In combination with the above steps S3211 to S3214, an example is given to illustrate the threshold setting, rendering logic and color gradient mapping strategy involved in the first color rendering processing of the embodiments of the present application.

[0076] Suppose the first temperature threshold is -22℃, the second temperature threshold is -18℃, and the third temperature threshold is -15℃. The first temperature threshold, the second temperature threshold, and the third temperature threshold can all be flexibly customized by the administrator in the background according to the specific requirements of the stored goods.

[0077] For the low-temperature normal region with an environmental temperature value in the low-temperature normal interval (e.g., ≤-22℃): rendered as dark blue. It represents that the temperature of this region is extremely low and in an ideal state.

[0078] For the standard normal region with an environmental temperature value in the standard normal interval (e.g., -22℃ to -18℃): rendered as light blue or green. It represents that the temperature of this region is within the set standard range and runs well.

[0079] For the pre-warning region with an environmental temperature value in the pre-warning interval (e.g., -18℃ to -15℃): rendered as orange or yellow. It represents that the temperature of this region has approached the set upper limit and needs attention, which may have potential risks such as insufficient refrigeration, poor cold air circulation, or opening the door for too long.

[0080] For the alarm region with an environmental temperature value in the alarm interval (e.g., >-15℃): rendered as flashing red. It represents that the temperature of this region has exceeded the standard, and the safety of the goods is directly threatened, which needs to be intervened immediately.

[0081] The embodiments of the present application complete the first color rendering processing to directly obtain the cold storage three-dimensional scene through step S410 in the case that the rendering object only includes different types of target rendering areas.

[0082] According to some embodiments of the present application, embodiment two: step S400 includes but is not limited to steps S420 to S430.

[0083] Step S420: In the case that the rendering object includes target rendering areas and device models corresponding to abnormal physical devices, the first color rendering processing is performed on each target rendering area of the second three-dimensional digital model according to the corresponding environment rendering mode, and a third three-dimensional digital model is obtained.

[0084] Specifically, the first color rendering processing of this step is the same as the first color rendering processing process of step S410, and the intermediate third three-dimensional digital model is generated through step S420, so as to facilitate subsequent second color rendering processing.

[0085] Step S430: according to the device rendering mode, performing second color rendering processing on the device model corresponding to the abnormal physical device in the third three-dimensional digital model, to obtain a cold storage three-dimensional scene.

[0086] Specifically, in step S430, in the third three-dimensional digital model, the device model corresponding to the abnormal physical device is rendered as a flashing red color, to obtain a cold storage three-dimensional scene.

[0087] Through steps S410 to S430, a visual cold storage three-dimensional scene can be generated based on the physical cold storage and the cold storage monitoring situation, so as to facilitate subsequent intuitive and rapid positioning of the occurrence position of the abnormal state in the physical cold storage based on the cold storage three-dimensional scene, thereby reducing the management difficulty and cost of the cold storage and improving the management efficiency of the cold storage.

[0088] Step S500: visualizing and displaying the cold storage three-dimensional scene on a monitoring interactive interface; wherein the cold storage three-dimensional scene displays abnormal alarm information.

[0089] It should be noted that, in order to clearly distinguish between fault phenomena and root causes, the cold storage environment data and the device state data are displayed in a separate and linked manner in the embodiments of the present application.

[0090] Specifically, visualizing and displaying the cold storage three-dimensional scene on the monitoring interactive interface includes: visualizing and displaying the three-dimensional digital model corresponding to the physical cold storage, visualizing and displaying the cold storage environment data, visualizing and displaying the device state data, and displaying the cold storage environment data and the device state data in a separate and linked manner.

[0091] Specifically, visualizing and displaying the three-dimensional digital model corresponding to the physical cold storage means: visualizing and displaying the three-dimensional digital model, while using different icons or animations to represent the device state (such as a rotating fan representing operation, and a red prohibition icon representing device failure).

[0092] Specifically, visualizing and displaying the cold storage environment data means: globally overviewing the cold storage environment data in a centralized list; the display position is in the upper left corner of the interface, and is fixedly displayed as an "environment parameter state overview table". The display logic is: all cold storage environment data (such as the temperature and humidity of each storage area) are displayed in real time in the form of a list. Each environment parameter in the cold storage environment data is independently judged, and the background color of the row where the environment parameter is located is highlighted (corresponding to using green / yellow / red) according to the alarm level (normal / early warning / alarm) of the environment parameter. This can provide a global situation, enabling the administrator to quickly grasp the number, position and severity level of all environmental abnormalities.

[0093] Specifically, the device status data visualization display refers to realizing three-dimensional positioning and root cause diagnosis; the display position of the device status data is on the corresponding device model in the three-dimensional digital model. The display logic is that when the physical device is abnormal, the device model corresponding to the abnormal physical device is directly displayed in the preset alarm color. When the alarm device is clicked, the system automatically generates and pops up a diagnosis text (such as: “fan FAN-07 failure, resulting in increased return air temperature”), directly explaining the failure cause and impact. Thus, the problem positioning can be upgraded from “where is abnormal” to “what is wrong and what is the consequence”, realizing root cause diagnosis and accurate positioning.

[0094] Specifically, the display of the cold storage environment data and the device status data in a separated and linked manner refers to that when the device failure causes the environment abnormality, the two display modes will work together. Specifically, the cold storage three-dimensional scene display has abnormal alarm information including device alarm information, environment data alarm information and three-dimensional scene alarm information. The device alarm information refers to the colored device model in the three-dimensional digital model and the fault diagnosis text displayed after clicking the colored device model. The environment alarm information refers to the highlighted cold storage environment data in the upper left corner overview table. The three-dimensional scene alarm information: the affected warehouse area and / or shelf are synchronously rendered in the environment alarm color.

[0095] The application obtains the device state data and the cold storage environment data in the physical cold storage through the controller in the process of monitoring the physical cold storage by using the three-dimensional visualization monitoring system; secondly, the device state data and the cold storage environment data are bound and associated with the first three-dimensional digital model constructed in advance to obtain a second three-dimensional digital model; wherein the physical cold storage includes physical devices, and the first three-dimensional digital model includes device models of the physical devices; then, the cold storage environment data and the device state data are monitored for abnormalities, and in the case that the obtained cold storage monitoring condition indicates that the physical cold storage has an abnormal state, the rendering object and the corresponding object rendering mode are determined according to the cold storage monitoring condition; wherein the rendering object only includes different types of target rendering areas in the second three-dimensional digital model; or the rendering object includes the target rendering areas and the device models corresponding to the abnormal physical devices; the different types of target rendering areas include a low-temperature normal area, a standard normal area, a pre-warning area and an alarm area; then, the second three-dimensional digital model is color rendered and alarm processed according to the rendering object and the corresponding rendering mode to obtain a cold storage three-dimensional scene; the visualized cold storage three-dimensional scene can be generated based on the physical cold storage and the cold storage monitoring condition, so as to reduce the cost of manual monitoring in online monitoring; finally, the cold storage three-dimensional scene is visualized and displayed on a monitoring interactive interface; the occurrence position of the abnormal state in the physical cold storage can be directly and quickly located through the visualized cold storage three-dimensional scene, the management difficulty and cost of the cold storage are reduced, and the management efficiency of the cold storage is improved. That is to say, the application embodiment can generate a visualized cold storage three-dimensional scene based on the physical cold storage and the cold storage monitoring condition, directly and quickly locate the occurrence position of the abnormal state in the physical cold storage based on the cold storage three-dimensional scene, reduce the management difficulty and cost of the cold storage, and improve the management efficiency of the cold storage.

[0096] According to some embodiments of the application, the three-dimensional visualization monitoring system further comprises a monitoring terminal in communication connection with the controller; after the cold storage three-dimensional scene is visualized and displayed on the monitoring interactive interface, the three-dimensional visualization monitoring method of the cold storage further comprises steps S600 to S700.

[0097] Step S600: in the case that the cold storage monitoring condition indicates that the physical cold storage has an abnormal state each time, the current cold storage three-dimensional scene is re-performed color rendering and alarm processing to obtain an updated cold storage three-dimensional scene, initial alarm processing is performed and a color temperature alarm event is recorded once.

[0098] Through step S600, each time the physical cold storage is detected to have an abnormal state, the current cold storage three-dimensional scene is updated to obtain the latest cold storage three-dimensional scene, so that the manager can timely know the abnormal state in the physical cold storage.

[0099] Further, the step S600 further comprises that the three-dimensional visual monitoring system background records each color temperature alarm event, including time, position, abnormal value, duration, etc., to form a traceable alarm log.

[0100] Step S700: In the case that the duration of the abnormal state of the physical cold storage is greater than the preset time, multi-level alarm processing is performed, and the abnormal state is sent to the monitoring terminal.

[0101] Through the step S700, if the abnormal state in the physical cold storage lasts more than the preset time without processing, the three-dimensional visual monitoring system can trigger a multi-level alarm mechanism, for example, from interface flashing to sending alarm push notifications to the monitoring terminal, and further upgrading to sending short messages or automatic telephone calls to the monitoring terminal to ensure that the alarm is delivered. Specifically, the monitoring terminal is a mobile phone APP; or the monitoring terminal can be a mobile tablet computer, etc.

[0102] According to some embodiments of the present application, after displaying the three-dimensional scene of the cold storage on the monitoring interactive interface, the three-dimensional visual monitoring method of the cold storage further comprises: displaying target query information in response to a query instruction input through the monitoring interactive interface. Specifically, the interactive query of the present application comprises: in response to a hovering instruction of a mouse, determining a target query area (the target query area can be any colored area) indicated by the hovering instruction, and immediately popping up an information box; the information box is small and used to display the core data (such as the current temperature, humidity, normal duration, and abnormal duration) of the target query area. In response to an input query click instruction, the target query area clicked by the query click instruction is determined, a detailed data panel is popped up on one side of the monitoring interactive interface, the detailed data panel is used to display a historical data curve graph of the associated sensor of the target query area to analyze the temperature change trend; and possible associated physical devices (such as nearby fans and refrigeration units) are listed, and the device running state of the physical device can be viewed one by one to assist fault root cause analysis.

[0103] It can be understood that the current most cold storage still uses the traditional monitoring means has the following defects: 1, the monitoring method is backward: relying on artificial regular inspection, reading the wired temperature and humidity instrument display number distributed in the cold storage everywhere and manual record, low efficiency, and there is the risk of record error, data forgery. 2, the information presentation is not intuitive: even if part of the cold storage adopts the automatic monitoring system, its management interface is mostly two-dimensional digital list, simple line chart or plane graph. When the cold storage scale is large, the number of sensors is large, the management personnel is difficult to quickly associate the abstract data with the specific physical position, and the overall and intuitive cognition cannot be formed. 3, the abnormal positioning is difficult: when the system alarms, the management personnel cannot quickly and accurately locate the specific position where the abnormality occurs from the two-dimensional interface, needs to enter the low temperature environment manually to check, consumes time and effort, and increases the personnel safety risk. 4, lack of depth information integration: the existing system can usually only display the sensor reading, and the running state (such as start-stop, current, voltage, fault code) of the key equipment such as the refrigeration unit, the fan and the access control is separated from the environmental data, and it is difficult to carry out linkage analysis.

[0104] The application provides a three-dimensional visual monitoring method and system for a cold storage, which can intuitively, efficiently and accurately display the overall and detailed state of the cold storage, so as to reduce the management difficulty, improve the operation efficiency and guarantee the storage safety. The application has the following beneficial effects: 1, extremely intuitive: the abstract data is converted into a visual three-dimensional scene, the management personnel can intuitively understand the overall state of the cold storage without reading complex reports, and the information understanding threshold is greatly reduced. 2, abnormal rapid positioning: through color temperature rendering and accurate mapping, the abnormal point (such as temperature abnormality of a shelf area) can be accurately positioned from the huge cold storage in a few seconds, and a lot of manual checking time is saved. 3, improve the management efficiency: the change from “people find information” to “information find people” is realized, the management omission is reduced, the decision efficiency is improved, and fewer management personnel can monitor more cold storages. 4, convenient for tracing and analysis: the three-dimensional visual scene is combined with the historical data, the state of the cold storage at any time point can be played back, and a powerful tool is provided for accident tracing and process optimization. 5, improve the safety: the number of personnel entering the low temperature environment for inspection is reduced, and the safety risk is reduced.
