Detailed Description
Referring to fig. 1-3, embodiments of the application of a refrigerated display case in different people stream conditions are shown. More specifically, referring to refrigerated display case 100 in either state, the refrigerated display case 100 includes a case body 110, a cabinet door 120, and timing and control portions not shown. The cabinet 110 has an inner accommodating space 111, and the inner accommodating space 111 serves as a commodity display area; the cabinet door 120 controllably opens or closes the inner accommodating space 111. More critically, the timing part is used for calculating the duration of the current cabinet door state of the refrigeration display cabinet, and finally the control part obtains a preset time period, and controls the cabinet door to be opened or closed based on the comparison result of the duration of the current cabinet door state and the preset time period.
The preset period acquired by the control part can comprise at least two situations. For example, it may be a preselected period of time during a local reference time, such as set to close cabinet door 120 at night 22:00-24:00. At this time, when the preset period initial value is reached, the control part will control the cabinet door 120 to be closed, and when the preset period end value is reached, the control part will release the closing control of the cabinet door 120, and the state of the cabinet door 120 in the next stage will be determined by the subsequent control method.
For another example, the preset period acquired by the control section may be a time period started after the trigger condition is reached, and the trigger state may be maintained for a preselected period. Such as whether 3 people are present around the display case and the duration exceeds 5 minutes. At this time, when the trigger condition is reached, that is, when 3 people exist around the showcase, the timing is started, and after the timing lasts for more than 5 minutes, the control part opens the control cabinet door 120; and re-time when less than 3 people are around the showcase, and after the time lasts for more than 5 minutes, the control part will release the opening control of the cabinet door 120, and the state of the cabinet door 120 at the next stage will be determined by the following control method.
Under the above arrangement, the refrigeration showcase 100 in this embodiment controls the opening or closing of the cabinet door 120 of the refrigeration showcase 100 by setting the control portion and based on the preset period, so as to open the cabinet door 120 in the estimated period with more people flow or the period with more people flow actually maintained, and close the cabinet door 120 in the estimated period with less people flow or the period with less people flow actually maintained, thereby realizing the matching of the open showcase state and the closed showcase state with the actual people flow condition, that is, the actual application condition of the showcase, and considering both the energy efficiency and the application convenience.
More specifically, in correspondence to the second example case of the preset period acquired by the control portion in the foregoing embodiment, the refrigeration display case 100 should further include a person identifying device 130 for identifying a person in the application scene of the refrigeration display case 100, thereby acquiring the people flow condition of the application scene associated with the display case, so that the control portion controls the door 120 to open or close based on the number of people in the application scene and the holding time period of the current number of people. As one example, the application scenario includes an area within a predetermined area around the refrigerated display cabinet 100, which may be a set value, or may encompass the entire application environment, such as an entire convenience store in which the refrigerated display cabinet 100 is used, etc.
In addition, refrigerated display cabinet 100 is typically equipped with lighting, temperature regulation, etc. functions, further improvements being made to relate these functions to the controls and control methods contemplated in the present application, as will be exemplified below.
For example, when the lighting part is provided in the interior accommodation space 111 of the refrigeration showcase 100, the control part controls the turning on or off of the lighting part based on a comparison result of the length of the current cabinet door state and the preset period. More specifically, the control section may also control the brightness of the illumination section in the illumination section on state. Therefore, the illumination part is started or the illumination brightness is improved at a stage of large people flow so as to facilitate the sales of commodities; and the lighting part is turned off or the lighting brightness is reduced at the stage of less people flow so as to save energy consumption.
As another example, when the refrigeration showcase 100 is provided with a temperature adjusting part for adjusting the temperature in the interior accommodating space 111, the control part also controls the operation state of the temperature adjusting part based on the comparison result of the length of the current cabinet door state and the preset period. Therefore, the operation power of the temperature regulating part is increased at a stage of larger people stream so as to maintain the refrigeration temperature of the sales commodity; and the operation power of the temperature regulating part is reduced in a period of less people flow so as to save energy consumption.
For another example, the control of the cabinet door 120 by the control part may be further refined to control the opening degree of the cabinet door 120.
In addition, although the specific structure for opening and closing the cabinet door 120 is not specifically described in the present application, the structural details of the cabinet door 120 are well known in the display case market, for example, the pivoting cabinet door 120 structure, the translational sliding door structure or the folding cabinet door 120 structure may be directly adopted. For another example, a structure of the cabinet door 120 that is hidden at the side wall of the accommodating space 111 inside the display cabinet can be adopted. All of the foregoing structures have been studied and embodied in the market or literature and are therefore not described herein.
With continued reference to fig. 1-3, the present application also provides a method for controlling the refrigeration display case 100 to achieve control of the state of the cabinet door 120 to better match the actual application situation. Specifically, when the refrigerated display cabinet 100 is in operation, the control method includes: s210, the timing part starts to calculate the duration of the current cabinet door state of the refrigeration display cabinet; and S220, controlling the cabinet door 120 to be opened or closed based on the comparison result of the duration of the current cabinet door state and the preset period.
By the method, the cabinet door 120 of the refrigeration display cabinet 100 can be controlled to be opened or closed based on the preset time period, so that the cabinet door 120 is opened in the estimated time period with more people flow or the time period with more people flow actually maintained, and the cabinet door 120 is closed in the estimated time period with less people flow or the time period with less people flow actually maintained, thereby realizing the matching of the open display cabinet state and the closed display cabinet state with the actual people flow condition, namely the actual application condition of the display cabinet, and considering the energy efficiency and the application convenience.
More specifically, step S220 further includes: during a first preset period corresponding to a greater people stream, controlling the door 120 to open; during a second preset period corresponding to a small or substantially no people stream, the control cabinet door 120 is closed; and a third preset period of time in the transition interval of the two, the control cabinet door 120 maintains the current state or releases the control of the cabinet door 120. The preset time period described herein can be set by a worker in the application scene of the display case according to actual experience thereof, or can be judged by setting specific people flow triggering conditions, so long as the final purpose is that the cabinet door 120 is opened for convenient use when the display case is used by more consumers, and the cabinet door 120 is closed for saving energy when the display case is used by fewer consumers.
For example, for the control described above that requires setting a particular people stream triggering condition, the refrigerated display cabinet 100 may further include a person identification device 130 for identifying persons within the application context of the refrigerated display cabinet 100. At this time, step S220 further includes: when the number of people in the application scene of the refrigeration display cabinet 100 exceeds the first preset number and is maintained for a fourth preset period, the current people flow is determined to be large, and the large people flow is continued for a period of time, so that the display cabinet needs to be frequently used, and the control cabinet door 120 is opened at the moment; when the number of people in the application scene of the refrigeration display cabinet 100 is lower than the second preset number and the fifth preset period is maintained, the current people flow is determined to be smaller, and the smaller people flow is continued for a period of time, so that the use frequency of the display cabinet is greatly reduced, and the control cabinet door 120 is closed at the moment; and when the number of people in the application scene of the refrigeration display cabinet 100 exceeds the second preset number and is lower than the first preset number and keeps the sixth preset period, the current people flow condition is considered to be moderate and the current people flow condition can last for a period of time, so that the cabinet door 120 does not need to be controlled deliberately, and the cabinet door 120 is controlled to keep the current state or the control of the cabinet door 120 is released.
In addition, refrigerated display cabinet 100 should typically be equipped with lighting, temperature regulation, etc. further improvements have been made to correlate these functions with the control methods contemplated in the present application, as will be exemplified below.
For example, when refrigeration display 100 includes an illumination portion for providing illumination to interior housing space 111, step S220 further includes: when the cabinet door 120 is opened, the stage of large people flow is considered, so that the illumination part is controlled to operate at the first brightness so as to facilitate commodity sales; and when the cabinet door 120 is closed, the stage of less people flow is considered, so the illumination part is controlled to operate at the second brightness smaller than the first brightness, so that the energy consumption is saved.
As another example, when the refrigeration display 100 includes a temperature adjusting portion for adjusting the temperature in the interior accommodating space 111, step S220 further includes: when the cabinet door 120 is opened, the stage of people flow is determined to be in a large stage, so that the temperature regulating part is controlled to operate at the first power so as to maintain the refrigeration temperature of the sales commodity; and when the cabinet door 120 is closed, the stage of less people flow is considered, so the temperature adjusting part is controlled to operate at a second power smaller than the first power, so that the energy consumption is saved.
To more clearly understand the foregoing embodiments, the control of the various portions of refrigerated display cabinet 100 in this application will be described in more detail below in connection with fig. 1-3.
In fig. 1, the timing part calculates the duration of keeping the current cabinet door state from the front and the late until the next day, namely 10:00 am, the time is the initial value of the preset period of extremely large people flow which is recognized by the staff in the application scene, and the recording and the setting are performed in the timing part, at this time, the control part controls the cabinet door 120 to be opened, controls the illumination part to illuminate with higher brightness, and controls the temperature regulating part to operate with higher power, so that the operation state of the display cabinet which is more convenient for selling goods is obtained.
In fig. 2, the timing part calculates the duration of the current cabinet door state of the refrigeration showcase from the afternoon of the day until the night of the day 22:00, the time is the initial value of the preset period of time when the people flow identified by the staff at the application scene is very small, and the recording and setting are performed in the timing part, at this time, the control part closes the control cabinet door 120, controls the illumination part to illuminate with lower brightness, and controls the temperature regulating part to operate with lower power, so as to obtain a display cabinet operation state with more energy consumption saving.
In fig. 3, the timing part calculates the duration of the current cabinet door state of the refrigeration showcase from the morning of the day to 15:00 pm of the day, the time is the initial value of the period of unobtrusive people stream data which is identified by staff at the application scene, and the timing part records and sets, at this time, the control part will release the control of the cabinet door 120, which can be in an open or closed state at will, or can be changed manually by consumers, and the corresponding lighting part and temperature adjusting part can also be changed along with the change. Therefore, the use convenience and the energy consumption saving are realized.
The above examples are primarily illustrative of the refrigerated display case of the present application and the method of controlling the same.
