Detailed Description
The following describes in more detail embodiments of the present invention with reference to the schematic drawings. Advantages and features of the present invention will become apparent from the following description and from the claims. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.
Referring to fig. 1 to 3, in which, fig. 1 shows a schematic view of a system for determining a load level of a freezing and refrigerating device according to a first embodiment of the present invention; fig. 2A and 2B are block diagrams illustrating a system for determining a load level of a refrigerating and freezing device according to a first embodiment of the present invention; fig. 3 is a schematic diagram showing preliminary information of the system for judging the load level of the refrigerating and freezing apparatus according to the first embodiment of the present invention. As shown in the figure, a system 100 for determining a load level of a freezing and refrigerating device includes a plurality of freezing and refrigerating devices, a plurality of sensing modules, a servo platform 3 and a plurality of playing modules, wherein the freezing and refrigerating devices draw six and mark the schematic representations of the freezing and refrigerating devices 1a, 1b, 1c, 1d, 1e and 1f, the sensing modules draw six and mark the schematic representations of the sensing modules 2a, 2b, 2c, 2d, 2e and 2f, and the playing modules draw six and mark the schematic representations of the playing modules 4a, 4b, 4c, 4d, 4e and 4 f. The freezing and refrigerating devices 1a, 1b, 1c, 1d, 1e, 1f may be refrigerators, freezers, ice stores, transparent display cabinets or other devices with freezing and refrigerating functions.
The sensing modules 2a, 2b, 2c, 2d, 2e, and 2f are respectively disposed in the freezing and refrigerating apparatuses 1a, 1b, 1c, 1d, 1e, and 1f, and are communicatively connected to the servo platform 3. The playback modules 4a, 4b, 4c, 4d, 4e, and 4f are also provided in the freezing and refrigerating apparatuses 1a, 1b, 1c, 1d, 1e, and 1f, respectively, and are communicatively connected to the server platform 3.
As illustrated by the refrigerating device 1a and the sensing module 2a, the refrigerating device 1a operates for several work cycles during a statistical time interval. Each internal duty cycle has a duty cycle time and a cooling parameter. The duty cycle time is comprised of a cool-down time and a down time. Wherein the last one of the work cycles is defined as a previous work cycle. The refrigeration parameter and the shutdown time corresponding to the previous working cycle are respectively defined as a previous refrigeration parameter and a previous shutdown time. Similarly, the freezing and refrigerating apparatuses 1b, 1c, 1d, 1e, and 1f are also the same.
The sensing module 2a is used for sensing the number of times of operation of the refrigerating and freezing device 1a, and sensing the refrigeration parameter and the downtime of the refrigerating and freezing device 1a in each operating cycle, and may be a sensor or other software, hardware or a combination thereof capable of knowing the refrigeration parameter and the downtime. Similarly, the sensing modules 2b, 2c, 2d, 2e, and 2f are also the same. The cooling parameter is defined herein as the sum of the products of all rotational speeds of each freezer and refrigerator during the cooling time and the operating time corresponding to all rotational speeds. The rotational speed refers to the rotational speed of the compressor, and is usually expressed in Revolutions Per Minute (RPM). Alternatively, the rotational speed may be several revolutions per second, several revolutions per hour, or hertz. Generally, the running time of the compressor is 40 to 60 minutes, and the shutdown time is 20 to 40 minutes; the speed of the fixed frequency compressor is about 3600rpm, and the speed of the variable frequency compressor is adjusted.
The servo platform 3 comprises a computing module 31 and a processing module 32 for receiving the working times, the refrigeration parameters and the downtime sensed by the sensing modules 2a, 2b, 2c, 2d, 2e, 2 f.
The operation module 31 averages all the refrigeration parameters and the down time within the statistical time interval, and calculates a refrigeration parameter average value and a down time average value, respectively, as shown in table one. Wherein, the statistical time interval can be a time interval of one day, one week, one month, one season, etc. The unit of the downtime can be seconds (sec), minutes (min), and hours (hr).
The processing module 32 is communicatively connected to the operation module 31 for comparing the previous refrigeration parameter with the average value of the refrigeration parameter to generate a comparison result of the refrigeration parameter, and comparing the previous downtime with the average value of the downtime to generate a comparison result of the downtime. When the current refrigeration parameter is larger than the average value of the refrigeration parameters, the comparison result of the refrigeration parameters is busy; otherwise, the comparison result of the refrigeration parameters is idle. When the last stopping time is smaller than the average stopping time, the stopping time comparison result is busy; otherwise, the idle time comparison result is idle. Then, the processing module 32 finds the load levels of the freezing and refrigerating devices 1a, 1b, 1c, 1d, 1e, 1f in a status lookup table according to the comparison result of the refrigeration parameters and the comparison result of the idle time, wherein the status lookup table is as the following table two.
Watch two
In the present embodiment, the processing module 32 includes a storage unit 321, and the storage unit 321 is used for storing the state lookup table.
The processing module 32 finds the preliminary load levels of the freezing and refrigerating devices 1a, 1b, 1c, 1d, 1e, 1f according to the first table and the second table, as shown in the third table.
Watch III
In the above example, the load level of the refrigerating and freezing apparatus is not 4, but the load level of the refrigerating and freezing apparatus is 4 as long as the comparison result of the refrigeration parameters of the refrigerating and freezing apparatus and the comparison result of the stop time are both busy.
The playing modules 4a, 4b, 4c, 4d, 4e, 4f are used to play the level information corresponding to the load level, respectively. In the present embodiment, the playing module 4a includes a display unit 41a, a speaker unit 42a and a sensing unit 43 a. Similarly, the other playing modules 4b, 4c, 4d, 4e, and 4f also include display units 41b, 41c, 41d, 41e, and 41f, speaker units 42b, 42c, 42d, 42e, and 42f, and sensing units 43b, 43c, 43d, 43e, and 43 f.
As illustrated by the playing module 4a, the display unit 41a can directly display the preliminary information corresponding to the preliminary load level of the freezing and refrigerating apparatus 1a, that is, directly display "1", where the preliminary information is to display the preliminary load level by using characters. The speaker unit 42a may directly play the preliminary information corresponding to the preliminary load level of the refrigerating and freezing apparatus 1a, for example: the speaker unit 42a broadcasts a phrase "the preliminary load level of the freezer-refrigerator is 1" or the like by voice. In this case, the preliminary information is a preliminary load level described by voice. The sensing unit 43a is used for generating an activating signal for activating the speaker unit 42a to play the preliminary message when sensing that a user is near the refrigerating and freezing device 1 a.
The operation principle of the other playing modules 4b, 4c, 4d, 4e, and 4f is the same, and therefore, the description thereof is omitted.
Therefore, after the playing modules 4a, 4b, 4c, 4d, 4e, 4f play the preliminary information corresponding to the respective preliminary load levels of the freezing and refrigerating apparatuses 1a, 1b, 1c, 1d, 1e, 1f, the user can know the preliminary load levels of the freezing and refrigerating apparatuses 1a, 1b, 1c, 1d, 1e, 1 f. The user can put the food material into the freezing and refrigerating device with lower initial load grade according to the initial load grade. In the present embodiment, the initial load levels of the freezing and refrigerating devices 1a, 1b, 1c, 1d, 1e, and 1f are "1", "2", "3", and "3", respectively, so that the user can preferentially put ingredients into the freezing and refrigerating device 1a having the initial load level of "1" and then the freezing and refrigerating device 1 b.
It should be noted that, in the embodiment, the playing module 4a includes the display unit 41a, the speaker unit 42a and the sensing unit 43a at the same time, but the disclosure is not limited thereto. The playing module 4a may only include one of the display unit 41a and the speaker unit 42a, or only include the sensing unit 43a and the speaker unit 42 a.
Finally, please refer to fig. 1, fig. 2A and fig. 2B, fig. 4A and fig. 4B to fig. 6 together, wherein fig. 4A and fig. 4B show a block diagram of a system for determining a load level of a freezing and refrigerating apparatus according to a second embodiment of the present invention; FIG. 5 is a block diagram of a processing module of a system for determining a load level of a freezer/refrigerator according to a second embodiment of the present invention; fig. 6 is a schematic diagram of a system for determining a load level of a refrigerating and freezing apparatus according to a second embodiment of the present invention. As shown, a refrigerating and freezing device load level determination system 100a is substantially the same as the refrigerating and freezing device load level determination system 100 shown in fig. 2A and 2B, and the differences are in the sensing modules 2aa, 2ba, 2ca, 2da, 2ea, 2fa and the servo stage 3 a.
The sensing module 2aa includes an open/close gate sensing unit 21 aa. The other sensing blocks 2ba, 2ca, 2da, 2ea, 2fa also include switching gate sensing units 21ba, 21ca, 21da, 21ea, 21 fa. The open/close door sensing units 21aa, 21ba, 21ca, 21da, 21ea, 21fa are each configured to sense a previous opening/closing time point of the freezing and refrigerating apparatuses 1a, 1b, 1c, 1d, 1e, 1 f.
The difference between the servo stage 3a and the servo stage 3 is the processing module 32 a. In the embodiment, the processing module 32a includes a storage unit 321, a first processing unit 322a, a first determining unit 323a, a second processing unit 324a, a second determining unit 325a, a third processing unit 326a, a third determining unit 327a, and a fourth processing unit 328a, wherein the storage unit 321 is the same as the storage unit 321 in the first embodiment, and therefore, the description thereof is omitted.
The first processing unit 322a uses the status lookup table to find the preliminary load levels of the freezing and refrigerating apparatuses 1a, 1b, 1c, 1d, 1e, and 1 f. The practical example of the first embodiment will continue to the present embodiment, i.e., table one, table two, and table three.
The first determining unit 323a is communicatively coupled to the first processing unit 322a for generating a first processing signal when determining that at least two of the preliminary load levels are the same. In this embodiment, the preliminary load levels of the freezing and refrigerating devices 1c, 1d, 1e, and 1f are all 3, so the first determining unit 323a generates the first processing signal.
The second processing unit 324a is communicatively connected to the first determining unit 323a for comparing the freezing and refrigerating apparatuses 1c, 1d, 1e, 1f with the same initial load level when receiving the first processing signal. In the present embodiment, the second processing unit 324a further compares the previous downtime of the freezing and refrigerating apparatuses 1c, 1d, 1e, 1f to obtain a first advanced load level of each of the freezing and refrigerating apparatuses 1c, 1d, 1e, 1f, as shown in the following table four. In addition, the playing modules 4c, 4d, 4e, and 4f respectively play a first step information corresponding to the first step load level. The previous downtime of the refrigerating and freezing apparatus 1c is 40, which is higher than 30 of the refrigerating and freezing apparatuses 1d, 1e, 1f, and indicates that the degree of idling of the refrigerating and freezing apparatus 1c is better than the degree of idling of the refrigerating and freezing apparatuses 1d, 1e, 1 f.
Watch four
The second determining unit 325a is communicatively coupled to the second processing unit 324a for generating a second processing signal when at least two of the first advanced load levels are determined to be the same. In this embodiment, the first advanced load levels of the freezing and refrigerating devices 1d, 1e, and 1f are all "2", so the second determination unit 325a generates the second processing signal. The third processing unit 326a is communicatively connected to the second determining unit 325a for comparing the freezing and refrigerating apparatuses 1d, 1e, and 1f with the same first advanced load level when receiving the second processing signal. In the present embodiment, the third processing unit 326a further compares the previous refrigeration parameters of the freezing and refrigerating devices 1d, 1e, 1f to obtain a second advanced load level of each of the freezing and refrigerating devices 1d, 1e, 1f, as shown in the following table five. In addition, the playing modules 4d, 4e, and 4f respectively play a second step information corresponding to the second step load level. The refrigeration parameter 90000 of the refrigerating and freezing device 1d is lower than the refrigeration parameter 135000 of the refrigerating and freezing devices 1e and 1f, and indicates that the refrigerating and freezing device 1d is more idle than the refrigerating and freezing devices 1e and 1 f.
Watch five
The third determining unit 327a is communicatively coupled to the third processing unit 326a for generating a third processing signal when determining that at least two of the second advanced load levels are the same. In this embodiment, the second advanced load levels of the freezing and refrigerating devices 1d and 1f are the same, so the third determining unit 327a generates the third processing signal. The fourth processing unit 328a is communicatively connected to the third determining unit 327a, and further compares the freezing and refrigerating apparatuses 1d, 1f having the same second step load level when receiving the third processing signal. In the present embodiment, the fourth processing unit 328a further compares the previous door closing time intervals of the freezing and refrigerating devices 1d, 1f to compare a final load level of each of the freezing and refrigerating devices 1d, 1f, as shown in the following table six. In addition, the playing modules 4d and 4f respectively play a final message corresponding to the final load level. The previous door closing time interval of the refrigerating and freezing device 1d is larger than that of the refrigerating and freezing device 1f, and in order to avoid the frequent door opening and closing times of the refrigerating and freezing device, the final load level of the refrigerating and freezing device 1d is prior to the refrigerating and freezing device 1 f.
Watch six
Therefore, the system 100a not only finds the preliminary load levels of the freezing and refrigerating devices 1a, 1b, 1c, 1d, 1e, and 1f, but also compares the first advanced load level, the second advanced load level, and the final load level according to the previous shutdown time, the previous refrigeration parameter, and the previous door closing time interval, as shown in the following table seven.
Watch seven
In more detail, referring to fig. 4A, 4B and 5, the computing module 31 transmits the signal S1 to the first processing unit 322a of the processing module 32 a. The signal S1 passes through the first determining unit 323a, the second processing unit 324a, the second determining unit 325a, the third processing unit 326a and the third determining unit 327a, and finally the fourth processing unit 328a generates signals S2, S3, S4, S5, S6 and S7, and transmits the signals S2, S3, S4, S5, S6 and S7 to the playing modules 4a, 4b, 4c, 4d, 4e and 4f, respectively.
Therefore, the playing modules 4a and 4b play the preliminary information of "1" and "2", respectively. The playing module 4c plays the preliminary information of "3" and additionally plays the first step information of "1". The playing module 4e plays the preliminary information of "3" and the first step information of "2", and additionally plays the second step information of "1". The playing modules 4d and 4f play the final information in addition to the preliminary information of "3", the first step information of "2", and the second step information of "2", wherein the playing module 4d plays the final information of "1", and the playing module 4f plays the final information of "2". As shown, the playing module 4d plays "3-2-2-1", and the two pieces of information may or may not be separated by "-".
In summary, the system for determining the load level of the freezing and refrigerating devices provided by the present invention can display the preliminary load levels of all the freezing and refrigerating devices for the user to view, which is equal to the priority order of the phase-change provided freezing and refrigerating devices. Therefore, the user can avoid the problems that food materials are too much or the door is frequently opened and closed to cause difficulty in keeping the food materials fresh or too high power consumption of the freezing and refrigerating device and the like when the food materials are placed into the freezing and refrigerating device with the higher initial load grade or are all placed into the same freezing and refrigerating device (such as the freezing and refrigerating device closest to the user).
In addition, the system for judging the load grade of the freezing and refrigerating device provided by the invention can further compare the first advanced load grade, the second advanced load grade and the final load grade of the freezing and refrigerating device through the factors such as the previous shutdown time, the previous refrigeration parameter, the previous door closing time interval and the like, so that a user can clearly know the initial load grade, the first advanced load grade, the second advanced load grade and the final load grade of each freezing and refrigerating device, and further know which freezing and refrigerating device the food materials are put into. The problems of too much food materials, too frequent door opening and closing, too high power consumption or too long downtime and the like in a single freezing and refrigerating device can be avoided.
