Fig. 1 is a schematic flow chart of a dew removal method provided in an embodiment of the present invention, applied to a target device having a light-transmitting area, as shown in fig. 1, the method includes the following steps:
and 102, sending a dew removal command based on the determined reflectivity.
It should be noted that the above-mentioned "inner surface of the light-transmitting region" generally refers to the side of the light-transmitting region facing away from the user, and the "outer surface of the light-transmitting region" generally refers to the side of the light-transmitting region facing toward the user. Taking the target device as a door body of the container as an example, the "inner surface of the light-transmitting area" generally refers to a side of the light-transmitting area on the door body, which faces the storage space of the container body, and the "outer surface of the light-transmitting area" generally refers to a side of the light-transmitting area on the door body, which faces away from the storage space of the container body.
Referring to FIG. 3, the dew condensation removing method in the embodiment of the present invention is described below by taking the target device as a glass door 200 of a cargo container, in which the above-mentioned light-transmitting area generally refers to the whole glass panel 202 of the glass door 200:
the light beam emitted from the inner surface of the glass panel 202 is divided into three parts: a portion of the light beam is transmitted through the glass panel 202, a portion of the light beam is absorbed by the glass panel 202, and the remaining portion of the light beam is reflected. When condensation does not occur on the outer surface of the glass panel 202, the light beam is reflected at the interface between the outer surface of the glass panel 202 and the air. When dew condensation occurs on the outer surface of the glass panel 202, the light beam is reflected at the boundary between the outer surface of the glass panel 202 and the dew condensation. Since the reflectivity of water is greater than that of air, the presence of condensation increases the reflectivity of the light beam at the outer surface of the glass panel 202. Thus, dew removal commands may be sent based on reflectivity.
As can be seen from the above, the dewing method determines whether the outer surface of the target device is dewed based on the difference in reflectivity between water and air, and when the outer surface of the target device generates dewing, the dewing may cause the reflectivity of the outer surface of the target device to increase, so that a dewing command may be timely transmitted based on the reflectivity. The change of the reflectivity is caused by the generation of condensation, so the reflectivity can directly reflect the condensation degree of the target equipment, the reliability is high, the condensation removing time can be accurately controlled according to the reflectivity, and the energy consumption is reduced.
In addition, in order to further improve the dew removal accuracy, the above-mentioned reflectance may be an average value of the reflectance at different positions on the outer surface of the light-transmitting region. When the dewdrop command is sent based on the reflectivity, the dewdrop time can be determined by comparing the reflectivity with the first preset reflectivity, and specifically, the dewdrop command is sent when the reflectivity is greater than the first preset reflectivity. The first preset reflectivity can be set according to actual conditions.
In the case that the reflectivity is greater than the first preset reflectivity, the dew removal command may be sent in various ways, for example:
the method comprises the steps of sending an intermittent dew removal command, wherein the intermittent dew removal command comprises a command of heating the target device and/or a command of blowing air to the outer surface of the target device. Taking the command to heat the target device as an example: when the reflectivity is greater than the first preset reflectivity and less than the second preset reflectivity, it is indicated that the condensation degree of the outer surface of the target device is not too serious, and at this time, a command of heating for a second preset time period at intervals of the first preset time period can be sent, wherein the second preset reflectivity is greater than the first preset reflectivity, and the second preset time period is less than the first preset time period. For example, a command to heat the target device every 100ms may be sent for 50 ms. And when the reflectivity is not less than the second preset reflectivity, it indicates that the condensation degree of the outer surface of the target device is relatively serious, at this time, the dew removal effect can be improved by shortening the heating interval time, the dew removal effect can also be improved by prolonging the heating time, the dew removal effect can also be improved by shortening the heating interval time and prolonging the heating time at the same time, that is, a command of heating every third preset time for a fourth preset time is sent. The third preset time is shorter than the first preset time, the fourth preset time is not shorter than the second preset time, and for example, a command of heating the target device for 80ms every 40ms can be sent; or the third preset time length is equal to the first preset time length, and the fourth preset time length is greater than the second preset time length.
And sending a continuous dew removal command, wherein the continuous dew removal command comprises a command for heating the target device and/or a command for blowing air to the outer surface of the target device. Taking the command of blowing the target device as an example: when the reflectivity is larger than the first preset reflectivity and smaller than the second preset reflectivity, the dew condensation degree of the outer surface of the target device is not too serious, and at the moment, a command of blowing according to a first wind speed, namely a first dew removal control parameter, can be sent. The second preset reflectivity is larger than the first preset reflectivity. And when the reflectivity is not less than the second preset reflectivity, the dew condensation degree of the outer surface of the target device is serious, at this moment, the dew removal effect needs to be improved by increasing the wind speed, namely, a command of blowing according to a second wind speed, namely a second dew removal control parameter is sent, wherein the second wind speed is greater than the first wind speed. It should be noted that, when the continuous dew condensation removing command is a command for heating the target device, the dew condensation removing step is substantially the same as the above except that the first dew condensation removing control parameter and the second dew condensation removing control parameter represent the heating temperature, that is, when the continuous dew condensation removing command is a command for heating the target device, the dew condensation removing effect can be improved by changing the heating temperature.
Of course, in either the first method or the second method, the dew removal command may be a heating command or a blowing command, and may also include both the heating command and the blowing command.
In addition, in the dewing process, as the dewing on the outer surface of the target device is reduced, the reflectivity of the outer surface of the target device is also reduced, so that when the reflectivity of the outer surface of the target device is not greater than the first preset reflectivity, which indicates that there is no dewing on the outer surface of the target device or very little dewing on the outer surface of the target device at this time, a dewing stop command may be sent, specifically, fig. 2 is a flowchart of another dewing method provided in an embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:
Certainly, in order to avoid the dew removing process, for example, heating or blowing the target device to affect the user experience, the personal information of the designated area on the periphery of the target device may also be obtained in real time in the dew removing process, and if the personal information is someone, that is, if there is a person in the designated area on the periphery of the target device, the dew removing stopping command is sent. Taking a container as an example, the target device is the glass door 200 of the container, and the designated area is an area where a user may stand when preparing to take goods from the container. For example, the designated area is a sector area located in front of the glass door 200 with the container as the center. Of course, the designated area may also be a rectangular area located in front of the glass door 200. In addition, the accumulated length of dew removal time in the whole dew removal process can also be used as a determining factor for determining the dew removal stopping time, for example, when the accumulated value of the second preset length of time and the fourth preset length of time is greater than the total preset length of time, a dew removal stopping command can be sent.
Further, the step of acquiring the optical signal of the light beam incident from the inner surface of the light-transmitting area and reflected by the outer surface of the light-transmitting area may be performed based on the request signal or may be performed in a preset cycle.
As shown in fig. 4, an embodiment of the present invention further provides a dew removal control apparatus, which includes an acquisition module 400, a determination module 410, and a control module 420, where the acquisition module 400 is configured to acquire an optical signal of a light beam incident from an inner surface of a light transmissive region of a target device and reflected by an outer surface of the light transmissive region; the determining module 410 is configured to determine the reflectivity of the outer surface of the light-transmitting area based on the light signal; the control module 420 is configured to send dew removal commands based on the reflectivity.
Further, the obtaining module 400 is further configured to obtain the personnel information of the designated area on the periphery of the target device; the control module 420 is also used for sending a dew removal stopping command if the personnel information is a person.
As shown in FIG. 3, the embodiment of the invention also provides a container, which comprises a container body 100, a door body, an emitter, a receiver, a dew removing device and the dew removing control device, wherein the door body is provided with a light-transmitting area, namely the door body. The door body is target equipment, and the emitter is used for emitting light beams from the inner surface of the light transmission area to the outer surface of the light transmission area; the receiver is used for receiving the light beam reflected by the outer surface of the light-transmitting area and sending a light signal to the dew removal control device, and the dew removal device is used for removing the dew on the outer surface of the door body.
The container can be, but is not limited to, a retail cabinet or a showcase, the door body can be a glass door 200, and the glass door 200 comprises a door frame 201 and a glass panel 202 embedded in the door frame 201. According to the container in the embodiment of the invention, whether the outer surface of the door body is dewed or not can be determined according to the reflectivity by adopting the dewing control device. Because the change of the reflectivity is caused by the generation of condensation, the reflectivity can directly reflect the condensation degree of the door body, the reliability is high, the condensation removing time can be accurately controlled according to the reflectivity, and the energy consumption is reduced.
Taking the target device as the glass door 200 as an example, the infrared emitter and the infrared receiver are both fixed on the inner surface of the glass door 200, and the infrared emitter emits a light beam from the inner surface to the outer surface of the glass door 200, and the light beam is received by the infrared receiver after being emitted from the outer surface of the glass door 200, that is, the infrared receiver is located on the reflected light path of the light beam. Wherein, the infrared transmitter and the infrared receiver can jointly form the infrared sensor 300, that is, the infrared sensor 300 is fixed on the inner surface of the glass door 200. Of course, in order to improve the dew removal accuracy, the inner surface of the glass door 200 may be provided with a plurality of infrared receivers and a plurality of infrared emitters.
It should be noted that the dew removing device can be, but is not limited to, a heater and/or a blowing assembly. Taking the target device as the glass door 200 as an example, the glass door 200 includes a door frame 201 and a glass panel 202 embedded in the door frame 201, and the heater at least includes a heating wire surrounding the door frame 201. The blowing assembly at least comprises a fan and an air deflector, an air channel is formed in the upper frame of the door frame 201, and the fan is arranged in the air channel; the bottom surface of the upper frame is provided with an air outlet communicated with the air duct, and the air deflector is arranged at the air outlet and used for guiding the air outlet of the air outlet to form an air curtain on the outer surface of the glass panel 202. Of course, the heater and blower assembly may take other configurations.

In addition, the logic instructions in the memory 520 may be implemented in software functional units and stored in a computer readable storage medium when the logic instructions are sold or used as a stand-alone product. Based on such understanding, the technical solution of the present invention may be embodied in the form of a software product, which is stored in a storage medium and includes instructions for causing a computer device (which may be a personal computer, a server, or a network device) to execute all or part of the steps of the method according to the embodiments of the present invention. And the aforementioned storage medium includes: a U-disk, a removable hard disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), a magnetic disk or an optical disk, and other various media capable of storing program codes.
