[0042] It should be understood that the specific embodiments described herein are merely exemplary and are not intended to limit the present application.

[0043] In a first aspect, the embodiments of the present application provide a refrigerated truck compartment drainage method.

[0044] Figure 1 A flowchart of the refrigerated truck compartment drainage method in an embodiment of the present application is shown.

[0045] Reference Figure 1 In an embodiment, the refrigerated truck compartment drainage method comprises the following steps:

[0046] S11, when the refrigerated truck is in a stationary state, the compartment posture, the temperature inside the compartment and the ambient temperature are monitored in real time;

[0047] The refrigerated truck refers to a closed compartment transport vehicle used to maintain the temperature of frozen or fresh goods. The refrigerated truck is a refrigerated special transport vehicle equipped with a refrigeration unit and a polyurethane insulated compartment. The key equipment mainly includes a refrigeration unit (independent and non-independent), an insulation compartment, a positioning management system integrating GPS / temperature detection technology / electronic map / wireless transmission technology.

[0048] The refrigerated truck is commonly used for transporting food, meat, fruits, vegetables, medicines, wine, etc. After transporting the goods, the insulation compartment needs to be inspected, mainly including the inspection of the outer surface of the compartment, the inner surface of the compartment, the corners inside and outside the compartment, the floor inside the compartment, and the interior lighting, refrigeration air outlet, etc.

[0049] For the inspection of the floor inside the compartment, one of the contents is drainage to prevent water accumulation and icing, which affects the insulation effect of the compartment, increases the overall weight of the vehicle, affects the loading, and increases fuel consumption. The existing technology uses the following scheme: if there is ice on the floor of the compartment, the user needs to use an ice shovel to remove it (note that the floor should not be scratched to avoid damage to the compartment); if there is water, the user needs to open the drainage valve or plug at the front of the refrigerated truck compartment after unloading the goods, and use the inclined posture of the compartment with the front low and the rear high when the refrigerated truck is empty to make the water inside the compartment flow out of the compartment through the drainage pipe under the action of gravity to realize drainage.

[0050] Figure 2 A structure diagram of the refrigerated truck compartment in an embodiment of the related art is shown.

[0051] Reference Figure 2The left side is a top view of the interior of the compartment, and the right side is a side view of the exterior of the compartment. The drain pipe is generally provided with an automatic drainage hole of 55-60 mm on the left and right sides of the front end of the compartment. In some embodiments, a rubber drain pipe is used, and a structural adhesive is used for sealing. However, the structural adhesive has a risk of cracking after a long time, which may cause damage to the floor of the compartment. In other embodiments, a stainless steel drain pipe is used, which is directly welded with the stainless steel bottom plate to form an integral body, which can effectively prevent water leakage.

[0052] From the above description, it can be analyzed that there are two links in the process of draining the refrigerated truck compartment. The first link is to determine the timing of draining. Obviously, the refrigerated truck cannot be drained when unloading is not completed, the posture of the refrigerated truck compartment does not meet the requirements, or ice is formed on the floor of the compartment. The timing of draining is needed to be determined. The second link is to open the device (drain valve or plug) for blocking the drain pipe at the timing suitable for draining. In the prior art, both links are dependent on manual operation, which results in high labor cost and time cost.

[0053] In this embodiment, three judgment elements are mainly set for the determination of the timing of draining, which are whether the refrigerated truck is in a stationary state, whether the compartment is in an inclined posture, and whether the temperature difference between the temperature in the compartment and the ambient temperature is less than or equal to a preset temperature difference. Among them, whether the refrigerated truck is in a stationary state is a prerequisite for the posture judgment of the compartment and the temperature difference judgment between the inside and outside of the compartment. It can be understood that when the refrigerated truck is in a driving state, most of the time is in transportation of goods, the compartment is fully loaded, and the refrigeration unit is turned on. Even if there is water in the compartment, it will freeze, and the compartment is in a stable posture. Even if there is no transportation of goods, from the perspective of road driving specification, the refrigerated truck in the driving state is not suitable for draining. Therefore, in this embodiment, the posture of the compartment, the temperature in the compartment, and the ambient temperature are monitored only when the refrigerated truck is in a stationary state.

[0054] Monitoring the posture of the compartment is to ensure that the current compartment is in an inclined posture, so that the water flow in the compartment can flow out of the compartment under the action of gravity through the drain pipe. On the other hand, it is to sense the unloading operation. When the posture of the compartment changes from stable to inclined, it indicates that the refrigerated truck is in the unloading process. During unloading, the refrigeration unit needs to be turned off. If the refrigeration unit is not turned off, when the compartment is opened, due to the fan of the evaporator of the refrigeration unit working, the front of the fan is positive pressure, and the back is negative pressure. The cold air blows out from the upper part of the compartment, and the hot air outside quickly enters the lower part of the compartment, causing the temperature in the compartment to rise rapidly, which affects the freshness of the goods. If the refrigeration unit is turned off, the fan is in a stopped state, the air flow stops, the air pressure inside and outside the compartment is consistent, and the speed of the hot air entering the compartment is relatively slow. In order to ensure the freshness of the goods, unloading needs to be completed within 5-10 minutes. On the basis of the compartment being in an inclined posture, if the temperature difference between the temperature in the compartment and the ambient temperature is less than or equal to a preset temperature difference, it is determined that the refrigerated truck compartment has been unloaded and is suitable for draining.

[0055] S12. If the compartment is tilted and the temperature difference between the compartment and the ambient temperature is less than or equal to the preset temperature difference, the automatic drainage function will be activated to control the automatic drainage valve to open and drain water.

[0056] In this embodiment, the device for sealing the drain pipe is set as an automatic drain valve, which can be automatically opened or closed by electronic control without manual operation. When drainage is appropriate, the automatic drainage function is activated to control the automatic drain valve to open and drain water. It should be noted that controlling the opening of the automatic drain valve is the main operation of the automatic drainage function, but the automatic drainage function is not limited to this operation. For example, if there is no standing water, the automatic drain valve may not need to be opened even if the automatic drainage function is activated. Or, for example, after drainage is completed, the automatic drain valve is closed to seal the drain pipe. The specific operation process of the automatic drainage function will be explained in detail with examples later.

[0057] Therefore, in this embodiment, when the refrigerated truck is stationary, the truck body's posture, internal temperature, and ambient temperature are monitored in real time. If the truck body is tilted and the temperature difference between the internal temperature and the ambient temperature is less than or equal to a preset temperature difference, the automatic drainage function is activated to control the automatic drainage valve to open and drain water. Through this embodiment, the timing of drainage is automatically determined based on the truck body's tilt posture and the temperature difference between the inside and outside of the truck body, and automatic drainage is achieved in conjunction with the automatic drainage valve, eliminating the need for manual judgment and operation, thereby reducing labor and time costs.

[0058] Figure 3 A schematic diagram of the process for activating the automatic drainage function in one embodiment of the present invention is shown.

[0059] Reference Figure 3 Furthermore, in one embodiment, the step of activating the automatic drainage function includes:

[0060] Real-time monitoring of water accumulation near drainage pipes;

[0061] If there is standing water near the drain pipe, the automatic drain valve will open.

[0062] In this embodiment, a water flow monitoring module is arranged near the drain pipe to monitor the water accumulation near the drain pipe in real time. After starting the automatic drainage function, if there is water accumulation near the drain pipe, the automatic drain valve is opened to drain water outside through the drain pipe. The water accumulation is continuously monitored during the drainage process to determine whether the water accumulation is drained. When it is monitored that there is no water accumulation near the drain pipe, it is determined that the water accumulation has been drained, and the automatic drain valve is closed. After starting the automatic drainage function, if there is no water accumulation near the drain pipe, the automatic drain valve remains closed. The goods in the refrigerated vehicle may not generate water flow each time, for example, some goods have special requirements and are first packed in a specific container or packaging and are subjected to low-temperature refrigeration, so that the goods can be unloaded without drainage. The water flow monitoring module can accurately determine the drainage requirement. In addition, it can also accurately determine whether the water accumulation is drained to timely control the automatic drain valve to be closed.

[0063] Figure 4 A flowchart for starting the automatic drainage function in another embodiment of the application is shown.

[0064] Referring to Figure 4 Further, in an embodiment, the step of starting the automatic drainage function comprises:

[0065] controlling the automatic drain valve to be opened, controlling the automatic drain valve to be closed after a preset time, and recording the drainage action information,

[0066] if the drainage action information exists, controlling the automatic drain valve to be closed;

[0067] The refrigerated vehicle compartment drainage method further comprises:

[0068] after the refrigeration unit is started, the drainage action information is cleared.

[0069] In this embodiment, another optional implementation is provided, which does not arrange the water flow monitoring module, and controls the automatic drain valve to be opened for a preset time after starting the automatic drainage function each time, and then keeps the automatic drain valve closed until the next time the automatic drainage function is started. The preset time is determined according to the actual situation to ensure that the water accumulation can be drained. The drainage action information is used to identify that the automatic drain valve has been opened after the automatic drainage function is started this time, and does not need to be opened again. Before the refrigerated vehicle is loaded, the refrigeration unit is started in advance to reach the temperature required by the goods, so that the quality of the goods does not change. After the refrigeration unit is started, the drainage action information is cleared to ensure that the automatic drain valve is normally controlled to be opened after the next time the automatic drainage function is started.

[0070] Further, in an embodiment, before step S11, it further comprises:

[0071] when the refrigerated vehicle is in a driving state and the refrigeration unit is started, the average inclination angle of the compartment body in a period of time is obtained;

[0072] The step of monitoring the posture of the compartment in real time comprises:

[0073] The current inclination angle of the compartment is acquired in real time;

[0074] If the angle difference between the current inclination angle and the average inclination angle is greater than or equal to the preset angle difference, it is determined that the compartment is in the inclined posture.

[0075] In the embodiment, the inclination angle monitoring module is arranged on the compartment to monitor the inclination angle of the compartment in real time. When the refrigerated truck is in the driving state and the refrigerating unit is turned on, the refrigerated truck is loaded with goods, the compartment is fully loaded and in a stable posture, and the average inclination angle of the compartment in a period of time is acquired as a reference for subsequent posture judgment of the compartment. After unloading, the compartment changes to the inclined posture, and the inclination angle of the compartment has an angle difference relative to the driving state. When the angle difference is greater than the preset angle difference, it is determined that the compartment is in the inclined posture. With the deformation of the elastic member of the whole vehicle, the inclination angle of the compartment in the empty state may change, and the preset angle difference can be calibrated regularly according to the actual situation of the compartment.

[0076] In addition, in the embodiment, the average inclination angle of the compartment is reacquired each time when the refrigerated truck is in the driving state and the refrigerating unit is turned on, so as to ensure the accuracy of the angle difference and eliminate the influence caused by the zero drift of the inclination angle monitoring module.

[0077] Further, in an embodiment, the step of monitoring the posture of the compartment in real time comprises:

[0078] The current inclination angle of the compartment is acquired in real time;

[0079] If the current inclination angle is greater than or equal to the preset angle threshold, it is determined that the compartment is in the inclined posture.

[0080] In the embodiment, another optional implementation is provided, in which the current inclination angle is compared with the preset angle threshold, and if the current inclination angle is greater than or equal to the preset angle threshold, it is determined that the compartment is in the inclined posture. It should be noted that the embodiment needs to ensure the accuracy of the measurement value of the inclination angle monitoring module. With the deformation of the elastic member of the whole vehicle, the inclination angle of the compartment in the empty state may change, and the preset angle threshold can be calibrated regularly according to the actual situation of the compartment.

[0081] Further, in an embodiment, the step S11 further comprises:

[0082] It is determined whether the refrigerated truck is in the stationary state according to the vehicle speed and / or the vehicle positioning.

[0083] In the embodiment, multiple optional ways are provided to determine whether the refrigerated truck is in the stationary state, i.e., the determination is made by whether the vehicle speed is zero, whether the vehicle positioning is moved, or by the combination of the two. The vehicle speed can be acquired through the instrument panel, and the vehicle positioning can be acquired through the GPS positioning module.

[0084] Figure 5 A flow chart of a method for draining a refrigerated truck compartment is shown.

[0085] Referring to Figure 5 Further, in an embodiment, the method for draining a refrigerated truck compartment further comprises:

[0086] When the refrigerated truck is in a stationary state, obtaining the road condition where the refrigerated truck is located;

[0087] If the refrigerated truck is not located on a flat road, the automatic draining function is closed.

[0088] In this embodiment, the condition for starting the automatic draining function is further increased to that the refrigerated truck is located on a flat road. When the refrigerated truck is located on a road with slope (uphill, downhill or left-right height difference), it is easy to affect the determination of the compartment posture and the accuracy of the determination of the draining time. Moreover, when the refrigerated truck is located on a road with slope, the water flow in the compartment can not be gathered near the drain pipe, and the normal draining cannot be performed.

[0089] As an optional implementation, the step of obtaining the road condition where the refrigerated truck is located comprises:

[0090] Obtaining the current position of the refrigerated truck through a GPS positioning module;

[0091] Determining the road condition corresponding to the current position through a high-precision map.

[0109] Further, in an embodiment, the condition monitoring module is configured to:

[0110] obtain a current inclination angle of the compartment in real time;

[0111] determine that the compartment is in an inclined posture if the current inclination angle is greater than or equal to a preset angle threshold.

[0112] Further, in an embodiment, the condition monitoring module is further configured to:

[0113] determine whether the refrigerated vehicle is in a stationary state according to a vehicle speed and / or a vehicle positioning.

[0114] Further, in an embodiment, the condition monitoring module is further configured to:
