Description

Technical Field

[0001] The present invention relates to the technical field of granary monitoring, and in particular to a granary monitoring system and method. Background Art

[0002] The storage temperature of grain is a key factor in determining its storage quality. When grains germinate, their metabolic activity will accelerate, generating a large amount of respiratory heat, causing the local temperature to rise, thus causing the grains to heat up and become moldy.

[0003] At present, granaries usually occupy a large area. Manually monitoring the temperature of each area is not only labor-intensive and inefficient, but also has a long detection cycle and is prone to omissions. In addition, the damage rate of the measuring equipment is high, and the accuracy of the measurement results cannot be guaranteed. These factors have hindered the digital management of grain temperature, resulting in problems such as grain infestation and mildew.

[0004] In the related art, the temperature is measured by vertically installed temperature cables inside the granary. These devices can set multiple temperature points on a probe rod to measure the temperature at different heights. However, the above schemes can usually only provide temperature data in the form of reports, which is not intuitive enough. In addition, the temperature values ​​obtained by these measurements reflect the air temperature in the granary, not the actual temperature of the grain itself, and cannot provide accurate information about the grain deterioration area and the temperature inside the grain.

[0005] Therefore, there is an urgent need for a monitoring system to achieve accurate monitoring and digital management of grain temperature in order to protect grain from insect infestation and mildew.

[0006] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0040] The present invention is described in detail below in conjunction with various embodiments.

[0041] Embodiment 1

[0042] According to an embodiment of the present invention, an embodiment of a granary monitoring system is provided.

[0043] Figure 1 is a schematic diagram of an optional granary monitoring system according to an embodiment of the present invention, such as Figure 1 As shown, the granary monitoring system includes: scanning equipment, temperature detection equipment and control module.

[0044] exist Figure 1 In the invention, a scanning device is deployed on the top of a granary to perform a three-dimensional scanning on the surface of grain in the granary to obtain grain characteristic information; a plurality of temperature detection devices are deployed in the lateral direction of the top of the granary, each temperature detection device extends downward to the bottom of the granary, and each temperature detection device is provided with a plurality of temperature sensors in the longitudinal height direction of the granary, and the temperature sensors are used to collect temperature information at different positions in the granary; a control module is communicatively connected with the scanning device and each temperature detection device to receive grain characteristic information and temperature information at different positions, and to process the grain characteristic information and temperature information at different positions to obtain the effective temperature value of the grain in the granary and the position information corresponding to the effective temperature value.

[0045] like Figure 1 As shown, a plurality of temperature detection devices (such as temperature detection devices 1 to 6) are deployed in the lateral direction of the top of the granary, each temperature detection device extends downward to the bottom of the granary, and each temperature detection device is provided with a plurality of temperature sensors in the longitudinal height direction of the granary, and the temperature sensors are used to collect temperature information at different positions in the granary; the control module communicates with the scanning device and the temperature detection device, and constructs a three-dimensional display diagram based on the received grain characteristic information and temperature information, wherein the three-dimensional display diagram is used to display the real-time grain parameter information of the granary.

[0046] In an embodiment of the present invention, at least one scanning device may be disposed on the top of the granary to scan the material surface (ie, the surface of the grain) in the granary through the scanning device to obtain material characteristic information (ie, grain characteristic information).

[0047] Optionally, the scanning device transmits and receives detection signals at least within a preset angle range to perform multi-point scanning of the material surface in the granary to obtain grain characteristic information. The grain characteristic information may include: the three-dimensional shape of the grain surface, grain volume, grain quality, grain height information (such as the highest material level, the lowest material level and the average material level, etc.), etc.

[0048] In the embodiment of the present invention, multiple temperature detection devices can be arranged in the horizontal direction of the granary roof, and each temperature detection device is provided with multiple temperature sensors in the vertical height direction of the granary, and the temperature values ​​at different positions in the granary are obtained through the temperature sensors. In addition, each temperature detection device needs to extend downward to the bottom of the granary (that is, each temperature detection device needs to penetrate the granary from top to bottom) to facilitate the measurement of the real-time temperature of the grain.

[0049] Here, the temperature information collected by each temperature sensor includes a temperature value and a corresponding temperature sensor number, so as to facilitate understanding of the specific location of the collected temperature value.

[0050] In the embodiment of the present invention, the control module can communicate remotely with the scanning device and the temperature detection device, and can analyze and process the effective temperature value of the grain in the granary and the position information corresponding to the effective temperature value according to the grain characteristic information sent by the scanning device and the temperature information sent by the temperature detection device, so as to construct a three-dimensional display diagram to display the real-time grain parameter information of the granary. In this way, the temperature of the grain in the granary can be intuitively understood according to the three-dimensional display diagram, and when over-temperature occurs, timely warning can be issued, which can effectively avoid grain loss.

[0051] It should be noted that there can be multiple granaries, and multiple granaries can share one control module, or one granary corresponds to one control module.

[0052] In summary, by deploying a scanning device on the top of the granary, deploying multiple temperature detection devices in the horizontal direction of the top of the granary, and extending each temperature detection device downward to the bottom of the granary, and setting multiple temperature sensors on each temperature detection device along the longitudinal height direction of the granary, and then constructing a three-dimensional display graph through the grain characteristic information sent by the scanning device and the temperature information sent by the temperature detection device received by the control module, so as to monitor the actual temperature of the grain in each area of ​​the granary in real time through the three-dimensional display graph, so as to be able to timely warn the areas with high grain temperature, thereby achieving the technical effect of real-time monitoring of grain temperature and reducing the problem of grain mildew, and solving the technical problem that the real temperature of grain cannot be accurately monitored in real time in the related technology, which makes the grain prone to mildew.

[0053] In the granary monitoring system provided in the first embodiment of the present application, the control module is used to display the grain characteristic information, the effective temperature value of the grain in the granary, and the position information corresponding to the effective temperature value in three dimensions in the display interface.

[0054] In an embodiment of the present invention, the control module can transmit grain characteristic information, the effective temperature value of grain in the granary, and the position information corresponding to the effective temperature value to an external central control room, so as to display this information in three dimensions on the display interface of the central control room. In this way, information such as the effective temperature of grain in each area of ​​the granary can be monitored in real time.

[0055] In the granary monitoring system provided in Example 1 of the present application, grain characteristic information includes at least one of the following: grain three-dimensional shape information, grain height information, grain volume information, grain quality information, and grain point cloud data; grain three-dimensional shape information is used to describe the spatial distribution of grain in the granary; grain height information includes at least one of the following: the lowest grain level, the highest grain level, and the average grain level.

[0056] In some optional embodiments, a scanning device can be used to transmit a signal to the grain in the granary, and determine the signal difference between the returned signal and the transmitted signal, so as to determine the three-dimensional shape information and grain height information of the grain in the granary based on the signal difference, and then determine the grain volume information, grain quality information, and grain point cloud data based on the three-dimensional shape information and grain height information of the grain, wherein the three-dimensional shape information of the grain is used to describe the spatial distribution of the grain in the granary; the grain height information includes at least one of the following: the lowest grain level, the highest grain level, and the average grain level.

[0057] In the embodiment of the present invention, a three-dimensional coordinate system of the granary can be established based on the granary information, that is, the granary is used as a reference to determine the coordinate system, for example, the center point position of the bottom of the granary is used as the coordinate origin of the coordinate system. Then, a scanning device (microwave radar or laser radar) can be used to transmit a microwave signal or a laser signal to the grain surface, and the distance between the top of the granary and the grain surface is determined according to the signal difference (for example, frequency difference) between the returned microwave signal or laser signal and the transmitted signal (that is, the transmitted microwave signal or laser signal) and the specific size information of the granary, and then the height and volume of the grain are determined according to the distance of each point on the grain surface, and the mass of the grain is determined in combination with the density of the grain, so that the grain characteristic information of the grain in the granary can be established on the three-dimensional coordinate system, that is, the grain height information, grain volume information, grain quality information, grain point cloud data and other information, all of which correspond to specific coordinate information, for example, the volume and mass of the grain in the area formed by the coordinate point A to the coordinate point B, the height of the grain along the height line of the granary where the coordinate point C is located, etc.

[0058] In order to improve the accuracy of determining the effective temperature value, in the granary monitoring system provided in Example 1 of the present application, the location area range of the grain in the granary is determined based on the three-dimensional shape information of the grain and the height information of the grain contained in the grain characteristic information; the location information of all temperature sensors located within the location area is screened; the temperature value in the temperature information corresponding to the location information of the screened temperature sensor is determined as the effective temperature value of the grain in the granary, and the location information of the temperature sensor is characterized as the location information corresponding to the effective temperature value.

[0059] In an embodiment of the present invention, the location area range of the grain in the granary can be determined based on the three-dimensional shape information of the grain and the height information of the grain included in the grain characteristic information, and then, each sensor position is compared with the location area range to screen all sensor positions within the location area range (i.e., the positions indicated by the location information of the temperature sensor), and then the temperature value corresponding to the sensor position (i.e., the temperature value in the temperature information corresponding to the location information) is determined as the effective temperature value of the grain in the granary (i.e., the actual temperature value of the grain itself in the granary), and the location information corresponding to the temperature sensor can be characterized as the location information corresponding to the effective temperature value.

[0060] Optionally, the grain point cloud data includes: multiple position coordinate information of the grain surface. In order to further determine the estimated temperature value corresponding to each position of the grain in the granary, in the granary monitoring system provided in Example 1 of the present application, the control module is also used to: determine multiple grain position coordinates inside the grain based on each position coordinate information and grain height information; determine the temperature sensor corresponding to the effective temperature value as the effective temperature sensor; determine multiple groups of adjacent temperature sensor sets based on the position information of the effective temperature sensor, and determine the sensor area corresponding to the adjacent temperature sensor set based on the position information of all effective temperature sensors in the adjacent temperature sensor set, wherein each group of adjacent temperature sensor sets contains at least two effective temperature sensors; determine the estimated temperature value corresponding to each grain position coordinate on the sensor area corresponding to the adjacent temperature sensor set based on the effective temperature value corresponding to each effective temperature sensor in the adjacent temperature sensor set.

[0061] In an embodiment of the present invention, multiple position coordinate information of the grain surface contained in the collected grain point cloud data can be combined with the grain height information of the grain in the granary to obtain multiple grain position coordinates of the grain in the granary, so as to determine the estimated temperature value of each grain position coordinate. In this way, the over-temperature area and over-temperature volume of the grain can be determined more accurately.

[0062] Optionally, the collected grain point cloud data includes multiple position coordinate information on the grain surface. By combining it with the grain height information in the grain feature information obtained by three-dimensional scanning, the grain height corresponding to each position coordinate information can be estimated, and then the position coordinate information and the corresponding grain height are combined to estimate all grain position coordinates at the grain height, thereby obtaining all grain position coordinates at all grain heights (i.e., all grain position coordinates at the height of the grain in the granary). Afterwards, the estimated temperature values ​​corresponding to each grain position coordinate of the grain in the granary can be integrated to obtain temperature point cloud data, so that the grain overtemperature area and grain overtemperature volume can be accurately estimated based on the temperature point cloud data. In the embodiment of the present invention, the estimated temperature value of each grain position coordinate is determined specifically as follows: the temperature sensor corresponding to the effective temperature value can be determined as the effective temperature sensor, and then based on the position information based on the effective temperature sensor, multiple groups of adjacent temperature sensor sets are determined (i.e., effective temperature sensors adjacent to each other in the upper, lower, left, and right directions can form a group of adjacent temperature sensor sets, and there can be repeated temperature sensors in multiple groups of adjacent temperature sensor sets, and each group of adjacent temperature sensor sets contains at least two effective temperature sensors), and then, based on the position information of all effective temperature sensors in the adjacent temperature sensor sets, the sensor area corresponding to the adjacent temperature sensor sets is determined (i.e., all temperature sensors in each group of adjacent temperature sensor sets are connected to outline the corresponding sensor area, which can be a cube or a plane area). Afterwards, based on the effective temperature value corresponding to each effective temperature sensor in the adjacent temperature sensor set, the estimated temperature value corresponding to each grain position coordinate on the sensor area corresponding to the adjacent temperature sensor set is estimated, for example, based on the temperature values ​​of the temperature sensors at the ends or the four corners, the temperature value of each point therein is estimated according to the distance ratio to obtain the estimated temperature value of each point.

[0063] Optionally, the control module is further used to average the effective temperature value or the estimated temperature value of the grain in the granary to obtain the real average temperature value of the grain in the granary.

[0064] In this embodiment, the control module can calculate the effective temperature values ​​or the average value of the estimated temperature values ​​of the grain in the granary at different positions to obtain the real average temperature value of the grain in the granary.

[0065] Alternatively, the control module is further configured to compare the effective temperature value or the estimated temperature value with a preset temperature threshold value to obtain the over-temperature area and over-temperature volume of the grain within the location area of ​​the grain in the granary.

[0066] In this embodiment, the control module can compare the effective temperature value or the estimated temperature value with a preset temperature threshold (i.e., a pre-set temperature threshold, which can be multiple) to obtain the over-temperature area and over-temperature volume of grain within the location area of ​​the grain in the granary.

[0067] In order to improve the accuracy of determining the location area range of the grain in the granary, in the granary monitoring system provided in Example 1 of the present application, based on the three-dimensional shape information of the grain, the bottom position area of ​​the grain in the bottom plane of the granary is determined; based on the height information of the grain, the height information of the grain in the granary corresponding to the bottom position area is determined; based on the bottom position area and the height information corresponding to the bottom position area, the location area range of the grain in the granary is determined.

[0068] In an embodiment of the present invention, the bottom position area of ​​the grain in the bottom plane of the granary can be determined based on the spatial distribution of the grain described by the three-dimensional grain morphological information. For example, the bottom position area of ​​the bottom plane of the granary where the grain is located can be determined using the established three-dimensional grain coordinate system as the reference coordinate system, and the height of the grain in each bottom position area can be determined based on the grain height information, that is, the height formed by the grain on the bottom position area, so as to obtain a grain height surface map corresponding to the bottom position area. Afterwards, the position area range of the grain in the granary is determined based on each bottom position area and the height corresponding to the bottom position area, that is, the three-dimensional space formed by each bottom position area and its corresponding grain height surface map, and these three-dimensional spaces constitute the position area range of the grain.

[0069] In the granary monitoring system provided in Example 1 of the present application, the step of screening the location information of all temperature sensors located within the location area includes: determining a target temperature detection device located within the location area where the grain is located; determining the sensor height value of each temperature sensor on each target temperature detection device; when the sensor height value is less than or equal to the height value indicated by the height information corresponding to the bottom location area where the target temperature detection device is located, determining the temperature sensor indicated by the sensor height value as the target temperature sensor, and determining the temperature value contained in the temperature information collected by the target temperature sensor as the valid temperature value.

[0070] In an embodiment of the present invention, the position area mapped on the bottom plane of the granary can be determined according to the position of the temperature detection device, and the temperature detection device indicated by the position area located in the bottom position area is determined as the target temperature detection device of the bottom position area. Then, the sensor height value of each temperature sensor on each target temperature detection device is determined. If the sensor height value is less than or equal to the height of the bottom position area corresponding to the target temperature detection device, it can be determined that the temperature sensor is located inside the grain and can measure the true temperature value of the grain. Therefore, the temperature sensor indicated by the sensor height value can be determined as the target temperature sensor, and the temperature value contained in the temperature information collected by the target temperature sensor can be determined as the effective temperature value.

[0071] In order to improve the accuracy of determining grain characteristic information, in the grain silo monitoring system provided in Example 1 of the present application, the number and position of scanning devices deployed on the top of each grain silo are determined based on the size information of the grain silo, and the scanning equipment includes at least one of the following: microwave radar, lidar, and binocular camera.

[0072] In an embodiment of the present invention, the size information of the granary can be determined or obtained first, including: the shape of the granary (such as a cylinder, a cuboid, etc.), height, width, etc., and then the number and position of scanning devices that need to be deployed on the top of the granary can be determined based on the specific size information of the granary. For example, the larger the granary, the more scanning devices are required.

[0073] In an embodiment of the present invention, the scanning device includes at least one of a 3D microwave radar, a 3D laser radar or a binocular camera.

[0074] In order to improve the accuracy of determining temperature information, in the granary monitoring system provided in Example 1 of the present application, multiple temperature detection devices are deployed symmetrically or asymmetrically in the lateral direction of the top of the granary, and multiple temperature sensors are arranged at equal or unequal intervals on each temperature detection device in the longitudinal height direction of the granary.

[0075] In order to accurately determine the location information of the sensor, in the granary monitoring system provided in Example 1 of the present application, each temperature detection device corresponds to a cable number and length, and each temperature sensor corresponds to location information.

[0076] In the embodiment of the present invention, multiple temperature detection devices can be deployed symmetrically or asymmetrically in the horizontal direction of the granary according to the size information of the granary, and multiple temperature sensors can be arranged at equal or unequal intervals in the vertical height direction of the granary. In addition, an independent cable number can be set for each temperature detection device, and the length of each temperature detection device can be determined to obtain the specific location information of each temperature sensor.

[0077] Figure 2is a top view of an optional temperature detection device according to an embodiment of the present invention, such as Figure 2 As shown in the figure, from the horizontal direction of the granary (i.e., the top view from the top to the bottom), there are 6 temperature detection devices installed in the granary, and from the vertical height direction of the granary (i.e., Figure 1 Each temperature detection device is provided with a plurality of temperature sensors, and the temperature values ​​at different positions in the granary can be obtained through the plurality of temperature sensors.

[0078] exist Figure 2 There are 6 temperature detection devices in the room, but due to space constraints, Figure 1 Only 5 temperature detection devices are displayed. Figure 2 The temperature detection devices numbered 5 and 6 are located in the front view direction (i.e. Figure 1 Only one temperature detection device can be seen in the orientation shown.

[0079] In order to improve the accuracy of three-dimensional display of grain characteristic information, effective temperature values ​​of grain in a granary, and position information corresponding to the effective temperature values ​​in a display interface, in the granary monitoring system provided in Example 1 of the present application, a three-dimensional coordinate system of the granary is established based on the size information of the granary, and a three-dimensional display graph is simulated on the three-dimensional coordinate system of the granary; the grain characteristic information, effective temperature values ​​of grain in the granary, and position information corresponding to the effective temperature values ​​are displayed on the three-dimensional display graph.

[0080] In order to further display the grain situation in three dimensions in the display interface, in the granary monitoring system provided in Example 1 of the present application, when the preset temperature threshold includes a first preset temperature threshold and a second preset temperature threshold, the position information corresponding to the effective temperature value less than or equal to the first preset temperature threshold is added to the first category position set, the position information corresponding to the effective temperature value greater than the first preset temperature threshold and less than or equal to the second preset temperature threshold is added to the second category position set, and the position information corresponding to the effective temperature value greater than the second preset temperature threshold is added to the third category position set; all the position information in the first category position set is displayed on the three-dimensional display graph in a first marking manner, all the position information in the second category position set is displayed on the three-dimensional display graph in a second marking manner, and all the position information in the third category position set is displayed on the three-dimensional display graph in a third marking manner.

[0081] In the embodiment of the present invention, the control module can display the temperature value and grain characteristic information in the granary in three dimensions on the display interface, so that the user can intuitively understand the information of the grain in the granary and the corresponding temperature information.

[0082] Specifically:

[0083] First, a three-dimensional coordinate system of the granary can be established according to the size information of the granary, and a three-dimensional display diagram can be simulated with the three-dimensional coordinate system of the granary as the reference coordinate system. Then, by setting one or more temperature thresholds, for example, setting two temperature thresholds T1 (such as the first preset temperature threshold) and T2 (such as the second preset temperature threshold), where T1 < T2, the control module analyzes and compares the selected valid temperature values with the temperature thresholds, and thus constructs a three-dimensional display diagram according to the comparison results.

[0084] In the embodiment of the present invention, if the set preset temperature thresholds include the first preset temperature threshold and the second preset temperature threshold, the position information indicated by the valid temperature values less than or equal to the first preset temperature threshold can be added to the first type of position set. The temperature in the grain area indicated by all the sensor positions in the first type of position set is the normal temperature and no operation is required. The position information indicated by the valid temperature values greater than the first preset temperature threshold and less than or equal to the second preset temperature threshold is added to the second type of position set. The temperature in the grain area indicated by all the sensor positions in the second type of position set exceeds the normal temperature and cooling is required. The position information indicated by the valid temperature values greater than the second preset temperature threshold is added to the third type of position set. The temperature in the grain area indicated by all the position information in the third type of position set is relatively high, and the grain may be damaged, so cooling is required and the damaged grain needs to be cleaned up.

[0085] In the embodiment of the present invention, in order to intuitively display different temperature regions of the grain in the granary, all the position information in the first type of position set can be displayed on the initial three-dimensional display diagram in the first marking manner (for example, the regions indicated by these sensor positions are displayed in green on the display interface); all the position information in the second type of position set is displayed on the initial three-dimensional display diagram in the second marking manner (for example, the regions indicated by these sensor positions are displayed in yellow on the display interface); all the position information in the third type of position set is displayed on the initial three-dimensional display diagram in the third marking manner (for example, the regions indicated by these position information are displayed in red on the display interface) to obtain a three-dimensional display diagram.

[0086] It should be noted that the above temperature thresholds (i.e., the first preset temperature threshold and the second preset temperature threshold) can be set to different temperature thresholds according to different grains, or one or two temperature thresholds can be set according to the specific actual situation, so as to screen and count the valid temperature values higher than the temperature thresholds and perform three-dimensional display in different colors on the display interface of the control module.

[0087] In order to further intuitively display more data on grain in the granary, in the granary monitoring system provided in Example 1 of the present application, after the location information corresponding to the effective temperature value greater than the second preset temperature threshold is added to the third type of position set, the grain over-temperature area and the grain over-temperature volume are determined based on the second type of position set; the grain damaged area and the grain damaged volume are determined based on the third type of position set, and the grain damage value is determined based on the grain damaged volume; the grain over-temperature area, grain over-temperature volume, grain damaged area, grain damaged volume and grain damage value are represented as grain parameter information, and the grain parameter information is displayed on a three-dimensional display graph.

[0088] In the embodiment of the present invention, the control module can analyze and count the effective temperature value (i.e., the effective temperature value) to obtain the real temperature value T of the grain in the granary. 真实 , average grain temperature T 平均 , the maximum temperature of grain T 最高 In addition, the control module can analyze and count all the location information in the second type of location set and the corresponding effective temperature values ​​to obtain the location area of ​​over-temperature grain (i.e., grain over-temperature area) and the volume of over-temperature grain (i.e., grain over-temperature volume). The control module can also analyze and count all the location information in the third type of location set and the corresponding effective temperature values ​​to obtain the location area of ​​possible damaged grain (i.e., grain damaged area) and the volume of possible damaged grain (i.e., grain damaged volume).

[0089] In the embodiment of the present invention, the control module can also calculate the quality and corresponding value information of the over-temperature grain in combination with the current grain price information, so as to assist the user to timely understand the grain parameter information in the granary during the intelligent management of the granary, specifically including: the real temperature value of the grain, the average temperature value of the grain, the highest temperature value of the grain, the volume of over-temperature grain, the area of ​​over-temperature grain, the corresponding loss of over-temperature grain, etc. In this way, the control module can intelligently manage and display the grain parameter information, so that the user can timely and intuitively understand the real situation of the grain in the granary, and timely cool or process the over-temperature grain.

[0090] For example, the damaged grain volume and the grain density ρ are combined to calculate the damaged grain mass m, that is, m=ρV is used to calculate the grain mass, where V is the damaged grain volume. Combined with the current unit price a of the grain, the damaged grain value P is calculated, that is, P=m*a is used to calculate the damaged grain value.

[0091] In the grain silo monitoring system provided in Example 1 of the present application, the control module displays the grain over-temperature area, grain over-temperature volume, grain damaged area, and grain damaged volume in the form of different color markings or different shape graphics on a three-dimensional display graph, and displays the grain damage value in digital form on the three-dimensional display graph.

[0092] In the embodiment of the present invention, the control module can display the grain overtemperature area, grain overtemperature volume, grain damage area, grain damage volume and grain damage value on the three-dimensional display map in different eye-catching ways, so that the user can intuitively understand the current situation of all grains in the granary. For example, the grain overtemperature area, grain overtemperature volume, grain damage area and grain damage volume are displayed on the three-dimensional display map in the form of different color markings or different shapes, and the grain damage value is displayed on the three-dimensional display map in digital form.

[0093] In an embodiment of the present invention, different colors or color shades can be used on the three-dimensional display diagram to represent different temperatures of grain, and the control module can highlight the over-temperature area, for example, marking it with a specific geometric shape, or highlighting it in red.

[0094] In the grain silo monitoring system provided in Example 1 of the present application, the control module issues alarm information for grain over-temperature areas, grain over-temperature volumes, grain damaged areas, and grain damaged volumes.

[0095] In some optional embodiments, the control module can perform an alarm operation when detecting an over-temperature area or a damaged area of ​​grain, for example, displaying the over-temperature area or the damaged area in red on the display interface, and at the same time, using a voice alarm to remind the user that there is over-temperature grain in the granary, or using text prompts on the display interface, etc., or using other methods to remind the user of abnormal grain conditions in the granary.

[0096] In order to achieve precise cooling of the over-temperature area in the granary, in the granary monitoring system provided in Example 1 of the present application, the granary monitoring system also includes: a cooling device, which communicates with the control module and is deployed on the side walls, bottom and top of the granary to cool the granary.

[0097] In an embodiment of the present invention, the granary monitoring system with temperature monitoring function also includes: a cooling device, which is communicatively connected to the control module and is used to control the output of the cooling amount according to the effective temperature value and over-temperature area (over-temperature position) obtained by analysis of the control module.

[0098] In the embodiment of the present invention, the cooling device is arranged on the side wall, bottom or top of the granary, and the cooling direction or cooling amount is controlled by the control module. In this way, the cooling direction and cooling amount can be precisely controlled according to the over-temperature area, thereby achieving precise cooling and saving cooling costs.

[0099] Optionally, the cooling device can be a ventilation system, a cooling system or a ventilation system combined with spraying, etc.

[0100] In the grain silo monitoring system provided in Example 1 of the present application, the control module generates a cooling control signal based on grain parameter information, and the cooling control signal includes at least: cooling duration, cooling amount and cooling position.

[0101] In this embodiment, the control module can generate a cooling control signal according to the grain parameter information to achieve precise control of the cooling device. The cooling control signal needs to include: cooling time, cooling amount and cooling position, so as to achieve precise cooling.

[0102] In order to improve the accuracy of precision cooling, in the grain silo monitoring system provided in Example 1 of the present application, a control module is used to determine the current grain over-temperature area, the current grain over-temperature volume, the current grain damaged area and the current grain damaged volume based on grain parameter information; the control module is used to determine the first cooling duration and the first cooling amount based on the current grain over-temperature volume, and a first cooling control signal is generated based on the first cooling duration, the first cooling amount and the current grain over-temperature area; the control module is used to determine the second cooling duration and the second cooling amount based on the current grain damaged volume, and a second cooling control signal is generated based on the second cooling duration, the second cooling amount and the current grain damaged area; the first cooling control signal and the second cooling control signal are sent to the cooling device, wherein the cooling device releases the first cooling amount to the current grain over-temperature area based on the first cooling control signal, and cools for the first cooling duration, and releases the second cooling amount to the current grain damaged area based on the second cooling control signal, and cools for the second cooling duration.

[0103] In the embodiment of the present invention, a corresponding relationship table between volume, cooling amount and cooling time can be constructed based on the cooling amount and cooling time used for the historical over-temperature volume of grain.

[0104] In an embodiment of the present invention, the control module can determine the current grain overtemperature area, the current grain overtemperature volume, the current grain damaged area and the current grain damaged volume according to the grain parameter information. Then, according to the current grain overtemperature volume, the first cooling time and the first cooling amount are determined from the relationship table, and according to the current grain damaged volume, the second cooling time and the second cooling amount are determined from the relationship table. Afterwards, the control module generates a first cooling control signal according to the first cooling time, the first cooling amount and the current grain overtemperature area, and generates a second cooling control signal according to the second cooling time, the second cooling amount and the current grain damaged area, so as to send the first cooling control signal and the second cooling control signal to the cooling device, so that the cooling device releases the first cooling amount to the current grain overtemperature area according to the received first cooling control signal, and performs cooling for the first cooling time, and releases the second cooling amount to the current grain damaged area according to the received second cooling control signal, and performs cooling for the second cooling time, thereby achieving precise cooling and saving cooling costs.

[0105] Exemplarily, when the cooling device is a ventilation system, multiple vents and ventilation ducts can be set on the top, bottom or side walls of the granary, and each vent is provided with a cooling fan. The cooling fan is wirelessly connected to the control module, and the specific cooling fan is controlled to operate according to the cooling control signal sent by the control module to release precise cooling amount to the corresponding grain area and maintain precise cooling time.

[0106] In the embodiment of the present invention, the grain storage monitoring system can monitor the temperature of grain in real time, and predict the possible grain deterioration area through intelligent analysis, take measures in advance, and effectively reduce the loss of grain caused by improper storage. In addition, the system has a high degree of automation, reduces manual intervention, improves work efficiency, and has significant benefits for large-scale grain storage.

Then, each effective temperature value is compared with a preset temperature threshold set (one or more temperature thresholds can be pre-set according to actual conditions) to obtain a comparison result, which includes a normal temperature area of ​​the grain, an over-temperature area of ​​the grain, and a loss area of ​​the grain, so that a three-dimensional display diagram can be generated according to the comparison result, so that different temperature areas of the grain are displayed with different marks using the three-dimensional display diagram, thereby realizing the function of monitoring the granary.
