DETAILED DESCRIPTION

[0020] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0021] In the description of the present application, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0022] In the description of this application, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed", etc. are understood to exclude the number itself, and "above", "below", "within", etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0023] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0024] In some cases, in the relevant technologies, with the development of the food delivery industry, the demand for delivery continues to rise. Especially in certain special periods, in order to avoid excessive contact between people, unmanned delivery vehicles came into being and gradually became widely used. However, these unmanned vehicles still face many challenges in the delivery process. As an area for temporary storage of food, the cargo hold is easily affected by adverse factors such as external environmental pollution and humidity fluctuations. Complex road conditions and changeable weather conditions may promote the growth of bacteria or viruses inside the cargo hold. For example, in the hot summer, the high temperature and high humidity environment in the cargo hold provides favorable conditions for the reproduction of microorganisms; and in the rainy season, rainwater may carry pollutants into the cargo hold, further increasing the risk of microbial growth. The presence of these microorganisms poses a serious threat to food hygiene and safety, and may cause foodborne diseases, thereby endangering the health of consumers.

[0025] However, traditional disinfection methods have some limitations: on the one hand, the disinfection time and frequency are usually fixed and cannot be flexibly adjusted according to the real-time environmental conditions in the cargo hold. For example, when the microbial risk is relatively low, high-intensity and long-term disinfection is still carried out according to the established mode, which not only consumes a lot of energy, but may also cause damage to the facilities and food packaging materials in the cargo hold due to excessive disinfection; and during the active period of microorganisms, the fixed disinfection process is difficult to ensure that the pathogens are completely eliminated. On the other hand, traditional disinfection methods lack real-time monitoring and feedback mechanisms for environmental factors, and cannot carry out targeted disinfection treatments for different environmental conditions. For example, it is impossible to dynamically adjust the disinfection intensity and duration according to changes in temperature and humidity in the cargo hold, resulting in unstable disinfection effects and difficulty in fully ensuring food safety.

[0026] Therefore, how to achieve intelligent disinfection of food cargo holds is the main problem currently facing the industry.

[0027] Based on the above situation, the present application proposes a control method, controller, medium and product for a food cargo hold, aiming to realize an intelligently disinfected food cargo hold.

[0028] The various embodiments of the food cargo hold of the present application are further described below in conjunction with the accompanying drawings.

[0029] like Figure 1 As shown, Figure 1 It is a schematic diagram of the structure of a food cargo hold provided in one embodiment of the present application.

[0030] In one embodiment, the food cargo hold includes a controller, a plurality of temperature and humidity sensors, a plurality of air quality sensors, and a plurality of disinfection lamps.

[0031] It can be understood that the controller is respectively connected to multiple temperature and humidity sensors, multiple air quality sensors and multiple disinfection lamps. The temperature and humidity sensors are used to obtain the current temperature and current humidity inside the food cargo hold, and the air quality sensors are used to obtain the current air quality data inside the food cargo hold.

[0032] It can be understood that the above-mentioned multiple disinfection lamps can be UV-C lamp tubes and can be set according to actual needs. The embodiments of the present application do not specifically limit them.

[0033] Illustratively, on the top of the food cargo hold, multiple disinfection lamps are arranged in a matrix, with the spacing between adjacent lamp tubes set at 15 cm, thereby ensuring that the space on the top of the food cargo hold is evenly covered by ultraviolet light, thereby effectively killing microorganisms on the surface of the cargo and in the top corners; on the walls on both sides of the food cargo hold, a staggered and inclined installation is adopted, with the angle between the disinfection lamp and the wall being 45 degrees, and adjacent disinfection lamps being 25 cm apart, so that ultraviolet light can better penetrate into the gaps and corners on the sides of the food cargo hold, avoiding blind spots for disinfection.

[0034] Exemplarily, multiple temperature and humidity sensors are installed at the four corners of the top of the food cargo hold, the center of the front and rear walls, and the bottom near the drain outlet, forming a full-range temperature and humidity monitoring network; multiple air quality sensors are symmetrically distributed in the middle of the left and right walls of the food cargo hold to ensure that the air quality data of different areas in the food cargo hold can be accurately collected; in addition, all temperature and humidity sensors and air quality sensors are equipped with double protection devices (such as UV shielding protective covers and waterproof, dustproof and anti-interference layers), and the signal transmission lines of each sensor use high-shielding performance cables to ensure the stability and accuracy of data transmission.

[0035] Additionally, in one embodiment, the food cargo hold further includes a Hall sensor.

[0036] It can be understood that the Hall sensor is connected to the controller to obtain the opening and closing status of the door of the food cargo hold.

[0037] Exemplarily, a Hall sensor is installed on the edge or door frame of the door of the food cargo hold, so as to use the change of magnetic field to detect the position change of the door, and then output a corresponding level signal to determine the opening and closing state of the door.

[0038] It is understood that the Hall sensor communicates with the controller through a reliable wired connection (such as a low-voltage signal line) to ensure the stability and timeliness of signal transmission. The Hall sensor can accurately detect the open and closed state of the door and transmit the corresponding signal to the controller. For example, when the door is closed, the Hall sensor sends a high level of 3.3V to the controller, and when the door is open, it sends a low level of 0V to the controller.

[0039] Based on the hardware structure of the food cargo hold in each of the above-mentioned embodiments, various embodiments of the control method of the food cargo hold of the present application are respectively proposed below.

[0043] It is worth noting that since the embodiments of the present application can judge the internal environment of the food cargo hold through the current temperature, current humidity and / or current air quality data, so as to control the working state of the disinfection lamp according to the internal environment of the food cargo hold, it is possible to achieve intelligent disinfection of the food cargo hold.

[0044] It can be understood that the above-mentioned current air quality data can be the current concentration of harmful gases, the current content of microbial spores, or the current concentration of harmful gases and the current content of microbial spores.

[0047] In one embodiment, when the current air quality data is less than or equal to the first preset threshold, it means that the current air quality is good, and the working state of the disinfection lamp is controlled by the current temperature and the current humidity; when the current air quality data is greater than the first preset threshold, it means that the current air quality is polluted, and the working state of the disinfection lamp is controlled by the current air quality data.

[0048] It can be understood that the embodiments of the present application can control the working state of the disinfection lamp by the current temperature and the current humidity when the current air quality is determined by the current air quality data, or control the working state of the disinfection lamp by the current air quality data, thereby realizing intelligent disinfection of the food cargo hold.

[0049] It can be understood that the above-mentioned first preset threshold can be set according to actual conditions, and the embodiment of the present application does not specifically limit it.

[0050] In addition, if Figure 4 As shown, Figure 4 It is a flow chart of a method for controlling a food cargo hold provided by another embodiment of the present application; regarding the above-mentioned step S310 in which the working state of the disinfection lamp is controlled according to the current temperature and the current humidity, it may include but is not limited to step S410, step S420 and step S430.

[0051] Step S410: When the current temperature is greater than or equal to the first preset temperature and less than or equal to the second preset temperature, and the current humidity is greater than or equal to the first preset humidity and less than or equal to the second preset humidity, control the disinfection lamp to disinfect the food cargo hold at a first preset power for a first preset time; Step S420: When the current temperature is greater than the second preset temperature and less than or equal to the third preset temperature, and the current humidity is greater than the second preset humidity and less than or equal to the third preset humidity, control the disinfection lamp to disinfect the food cargo hold at the second preset power for a second preset time; Step S430: When the current temperature is greater than the third preset temperature and the current humidity is greater than the third preset humidity, control the disinfection lamp to disinfect the food cargo hold at a third preset power for a third preset time.

[0052] In one embodiment, when the current temperature is greater than or equal to the first preset temperature and less than or equal to the second preset temperature, and the current humidity is greater than or equal to the first preset humidity and less than or equal to the second preset humidity, it means that the internal environment of the food cargo hold is in a low-risk environment at this time, so that the disinfection lamp is controlled to disinfect the food cargo hold with a first preset power for a first preset time; when the current temperature is greater than the second preset temperature and less than or equal to the third preset temperature, and the current humidity is greater than the second preset humidity and less than or equal to the third preset humidity, it means that the internal environment of the food cargo hold is in a medium-risk environment, so that the disinfection lamp is controlled to disinfect the food cargo hold with a second preset power for a second preset time; when the current temperature is greater than the third preset temperature and the current humidity is greater than the third preset humidity, it means that the internal environment of the food cargo hold is in a high-risk environment, so that the disinfection lamp is controlled to disinfect the food cargo hold with a third preset power for a third preset time; therefore, the embodiment of the present application can realize intelligent disinfection of food cargo holds.

[0053] It can be understood that the above-mentioned first preset temperature can be 18 degrees Celsius, which can be set according to actual conditions, and the embodiment of the present application does not make any specific limitation on it.

[0054] It can be understood that the above-mentioned second preset temperature can be 23 degrees Celsius, which can be set according to actual conditions, and the embodiment of the present application does not make any specific limitation on it.

[0056] It can be understood that the first preset humidity mentioned above can be 35% humidity, which can be set according to actual conditions, and the embodiment of the present application does not make any specific limitation on it.

[0057] It can be understood that the above-mentioned second preset humidity can be 55% humidity, which can be set according to actual conditions, and the embodiment of the present application does not make any specific limitation on it.

[0058] It can be understood that the third preset humidity mentioned above can be 75% humidity, which can be set according to actual conditions, and the embodiment of the present application does not make any specific limitation on it.

[0059] It can be understood that the above-mentioned first preset power can be 50% of the maximum output power and can be set according to actual conditions. The embodiment of the present application does not make any specific limitation on it.

[0060] It can be understood that the above-mentioned second preset power can be 75% of the maximum output power and can be set according to actual conditions. The embodiment of the present application does not make any specific limitation on it.

[0061] It can be understood that the third preset power mentioned above can be the maximum output power and can be set according to actual conditions. The embodiment of the present application does not specifically limit it.

[0062] It can be understood that the above-mentioned first preset duration can be 15 minutes, which can be set according to actual conditions, and the embodiment of the present application does not make any specific limitation on it.

[0063] It can be understood that the above-mentioned second preset duration can be 30 minutes, which can be set according to actual conditions and is not specifically limited in the embodiment of the present application.

[0064] It is understandable that the third preset duration mentioned above can be 60 minutes, which can be set according to actual conditions, and the embodiment of the present application does not make any specific limitation on it.

[0065] In addition, if Figure 5 As shown, Figure 5 It is a flow chart of a method for controlling a food cargo hold provided by another embodiment of the present application; regarding the above-mentioned step S320 in which the working state of the disinfection lamp is controlled according to the current air quality data, it may include but is not limited to step S510 and step S520.

[0066] Step S510: When the current air quality data is greater than the first preset threshold and less than or equal to the second preset threshold, control the disinfection lamp to disinfect the food cargo hold at a second preset power for a second preset time; Step S520: When the current air quality data is greater than the second preset threshold, control the disinfection lamp to disinfect the food cargo hold at a third preset power for a third preset time.

[0067] In one embodiment, when the current air quality data is greater than the first preset threshold and less than or equal to the second preset threshold, it means that the air quality at this time is slightly polluted, and the internal environment of the food cargo hold is in a medium-risk environment, so that the disinfection lamp is controlled to disinfect the food cargo hold at a second preset power for a second preset time; when the current air quality data is greater than the second preset threshold, it means that the air quality at this time is severely polluted, and the internal environment of the food cargo hold is in a high-risk environment, so that the disinfection lamp is controlled to disinfect the food cargo hold at a third preset power for a third preset time; therefore, the embodiment of the present application can realize intelligent disinfection of food cargo holds.

[0068] It can be understood that the above-mentioned second preset threshold can be set according to actual conditions, and the embodiment of the present application does not specifically limit it.

[0069] In addition, if Figure 6 As shown, Figure 6 This is a flow chart of a method for controlling a food cargo hold provided by another embodiment of the present application; the method for controlling a food cargo hold may also include but is not limited to step S610 and step S620.

[0070] Step S610, obtaining the opening and closing status of the door of the food cargo hold through the Hall sensor; Step S620: Control the working state of the disinfection lamp according to the opening and closing state.

[0071] In one embodiment, the embodiment of the present application uses a Hall sensor to obtain the opening and closing status of the door of the food cargo hold, thereby controlling the working state of the disinfection lamp according to the opening and closing status, thereby realizing intelligent disinfection of the food cargo hold.

[0072] In addition, if Figure 7 As shown, Figure 7 It is a flow chart of a method for controlling a food cargo hold provided by another embodiment of the present application; regarding the above-mentioned step S620 in which the working state of the disinfection lamp is controlled according to the current air quality data, it may include but is not limited to step S710 and step S720.

[0073] Step S710: When the opening and closing state is the first preset state, the working state of the disinfection lamp is controlled according to the current temperature, the current humidity and / or the current air quality data; Step S720: When the opening and closing state is the second preset state, the disinfection lamp is controlled to be in a safety locked state.

[0074] In one embodiment, when the opening and closing state is a first preset state, it means that the hatch is in a closed state at this time, so that the working state of the disinfection lamp is controlled by the current temperature, current humidity and / or current air quality data; when the opening and closing state is a second preset state, it means that the hatch is in an open state at this time, so that the disinfection lamp is controlled to be in a safe locked state; therefore, the embodiment of the present application can realize intelligent disinfection of food cargo holds.

[0075] It is understandable that when the cabin door is in the open state, controlling the disinfection lamp to be in a safe locked state can prevent the risk of ultraviolet rays leaking into the external environment, thereby avoiding harm to the human body caused by ultraviolet rays.

[0076] In addition, if Figure 8 As shown, Figure 8 It is a flow chart of a method for controlling a food cargo hold provided by another embodiment of the present application; the method for controlling a food cargo hold may also include but is not limited to step S810 and step S820.

[0077] Step S810, obtaining the operating status of the temperature and humidity sensor and the air quality sensor; Step S820: When the operating status of the temperature and humidity sensor and / or the air quality sensor is in an abnormal state, the disinfection lamp is controlled to be in a standby state and an abnormal alarm is issued.

[0078] In one embodiment, the embodiment of the present application will obtain the operating status of the temperature and humidity sensor and the air quality sensor. When the operating status of the temperature and humidity sensor and / or the air quality sensor is in an abnormal state, the disinfection lamp is controlled to be in standby mode and an abnormal alarm is issued; therefore, the embodiment of the present application can remind relevant delivery personnel to pay attention to and deal with abnormal conditions of the sensors in a timely manner, which helps to promptly discover and solve problems and avoid potential safety hazards.

[0079] Based on the control methods of the food cargo hold of the above-mentioned various embodiments, overall embodiments of the control methods of the food cargo hold of the present application are respectively proposed below.

[0080] The current temperature and humidity inside the food cargo hold are obtained through multiple temperature and humidity sensors; the current air quality data inside the food cargo hold is obtained through multiple air quality sensors to determine the current air quality based on the current air quality data.

[0081] It can be understood that the above-mentioned current air quality data can be the current concentration of harmful gases, the current content of microbial spores, or the current concentration of harmful gases and the current content of microbial spores. It can be set according to actual conditions, and the embodiments of the present application do not specifically limit it.

[0082] When the current temperature is between 18-23°C, the current humidity is between 35-55% and the air quality is good, it is judged as a low-risk environment. The disinfection lamp is started at 50% of the maximum output power for 15 minutes for routine maintenance disinfection.

[0083] When the current temperature is between 23-28°C, the current humidity is between 55-75%, or the air quality is slightly polluted, it is judged as medium-risk mode, and the disinfection lamp is started to run at 75% of the maximum output power for 30 minutes.

[0084] When the current temperature exceeds 28°C, the current humidity is higher than 75%, or the air quality is seriously polluted, it is judged as high-risk mode and the disinfection lamp is started to run at 100% power and full load. The disinfection time is set to 60 minutes to ensure that the germs are completely killed.

[0085] It can be understood that when the current air quality data is less than or equal to the first preset threshold, it means that the current air quality is good; when the current air quality data is greater than the first preset threshold and less than or equal to the second preset threshold, it means that the air quality at this time is slightly polluted; when the current air quality data is greater than the second preset threshold, it means that the air quality at this time is seriously polluted.

[0086] Real-time abnormal monitoring and intelligent alarm mechanism The system continuously monitors all sensor data and sets multi-dimensional abnormal thresholds. Temperature change rates exceeding 3°C / minute, humidity sudden changes exceeding 20%, and air quality parameters deteriorating beyond a set ratio in a short period of time are all considered abnormal. Once an abnormality is detected, the system immediately suspends the disinfection lamp and starts the intelligent alarm program. Alarm methods include but are not limited to sound and light alarms in food cargo holds, sending emergency signals to the remote monitoring platform, and pushing alarm notifications to the mobile terminals of relevant delivery personnel to ensure that timely response measures are taken.

[0087] In addition, the embodiment of the present application also obtains the opening and closing state of the hatch of the food cargo hold through the Hall sensor, and immediately judges the state of the hatch after receiving the signal of the Hall sensor.
