Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a warehouse temperature control method includes step S100, step S200, and step S300.
And S100, when the door of the warehouse is closed, acquiring temperature data of goods stored in the warehouse.
Specifically, when the warehouse door is closed, the whole warehouse temperature control scheme is triggered, and the scheme firstly obtains the temperature data of the stored goods through the controller, namely obtains the surface temperature of the goods stored in the warehouse. It will be appreciated that in one embodiment, the closing of the warehouse door may be achieved by the triggering device, i.e. when the warehouse door is closed, the triggering device will receive a triggering signal, and the controller receives the triggering signal, i.e. the closing of the warehouse door is indicated. In another embodiment, it may also be determined whether the warehouse door is closed through an instruction sent by the user, that is, when the warehouse door is closed, the user may send an instruction to the controller, and when the controller receives the instruction, the controller considers that the warehouse door is closed.
It should be noted that the manner of obtaining the temperature data of the stored goods in the warehouse is not exclusive, and in one embodiment, the temperature data of the goods may be collected by the user and then sent to the controller for analysis processing by the user. In another embodiment, the operation of collecting the surface temperature of the goods can be performed in real time through a goods temperature collector, the goods temperature collector is connected with the controller, and the collected temperature data are sent to the controller in real time for further analysis and processing. For example, in one embodiment, the warehouse temperature control system is provided with an infrared temperature collector, and when the warehouse door is closed, the triggering device is opened, so that the infrared temperature collector is opened to operate, and the temperature data acquisition operation of goods stored in the warehouse is carried out in real time.
And S200, comparing and analyzing the temperature data with a corresponding preset cargo temperature range.
Specifically, the preset cargo temperature range is a maximum allowable temperature range value that does not require rapid cooling (i.e., temperature reduction) of the cargo, that is, when the temperature data exceeds a maximum value of the preset cargo temperature range, it indicates that rapid cooling of the cargo is required. The temperature range of the preset goods is pre-stored in the controller, and after the controller acquires the temperature data of the goods stored in the storehouse, the temperature data and the temperature range of the preset goods are compared and analyzed, and whether the goods need to be rapidly refrigerated is judged.
It should be noted that, in an embodiment, the preset cargo temperature ranges corresponding to each cargo may be different from each other, in which case, the preset cargo temperature ranges of a plurality of different cargos are prestored in the controller, and after the controller obtains the temperature data, the temperature data is compared and analyzed with the preset cargo temperature range corresponding to the cargo. That is, in this embodiment, after the controller acquires the temperature data, the controller may further acquire a cargo type corresponding to the temperature data, and then obtain a preset cargo temperature range corresponding to the cargo type by combining the cargo type, and compare and analyze the acquired temperature data with the preset cargo temperature range.
In another embodiment, there may be only one preset cargo temperature range, that is, the preset cargo temperature ranges corresponding to different types of cargo are the same. After the controller acquires the temperature data of the stored goods, the temperature data and the preset goods temperature range are directly compared and analyzed. How to set the preset goods temperature range can be selected by combining practical application scenes through a user.
And step S300, when the temperature data meet the preset goods temperature range, adjusting the frequency of a compressor of the air cooler according to the average environment temperature of the warehouse.
Specifically, the average ambient temperature of the warehouse is obtained by analyzing the ambient temperature collected by the ambient temperature collectors uniformly arranged in the warehouse. The temperature data satisfies and predetermines the goods temperature range and indicates that the temperature data is in predetermineeing the goods temperature range promptly, indicates this moment and need not carry out quick refrigeration to the goods to reduce the temperature of goods and save. When the temperature data meet the preset goods temperature range, the controller can further combine the internal environment temperature of the storehouse to realize temperature control, namely, the running frequency of the compressor is controlled to realize the temperature regulation operation in the storehouse. This embodiment is specifically through evenly setting up a plurality of ambient temperature collectors in the storehouse and carrying out ambient temperature collection and sending, the controller sums after receiving each ambient temperature to calculate according to the quantity of ambient temperature collector, finally obtain the average ambient temperature in storehouse, according to the actual size of the average ambient temperature in storehouse, adjust the compressor operating frequency of air-cooler, in order to increase or reduce the refrigerating output, finally realize the regulation operation of the inside temperature in storehouse (also be storage temperature).
It should be noted that the number of the ambient temperature collectors is not exclusive, and may be selected according to the size of the warehouse and the user requirement. It is to be appreciated that in one embodiment, the temperature data satisfying the preset cargo temperature range may be the temperature data being within the preset cargo temperature range. In another embodiment, since the goods are generally stored in a lower temperature environment in the goods storage, the temperature data satisfying the preset goods temperature range may be further understood as the temperature data being less than or equal to the maximum value of the preset goods temperature range. Also can think that need not carry out rapid cooling to the goods this moment when temperature data is less than the minimum of predetermineeing goods temperature range, can carry out the operation of adjusting the compressor frequency of air-cooler according to the average ambient temperature in storehouse this moment equally.
Referring to fig. 2, in an embodiment, after step S200, the method further includes step S400.
And S400, when the temperature data is larger than the maximum value of the preset goods temperature range, controlling a compressor of the air cooler to operate at the maximum frequency until the temperature data meets the preset goods temperature range.
Specifically, after the storehouse door is closed and the storehouse temperature control operation is triggered, the controller compares and analyzes the temperature data of the stored goods with the preset goods temperature range, and the condition that the temperature data is larger than the maximum value of the preset goods temperature range also occurs, namely, the surface temperature of the current goods is too high. Under this kind of condition, storehouse temperature control system will carry out the temperature processing of drawing the temperature fast to the goods, reduces goods surface temperature (also be the temperature data of storage goods) to satisfying preset goods temperature range. Specifically, the compressor frequency of cooling mode through control air-cooler realizes, through control compressor with the maximum frequency operation, what the air-cooler corresponded this moment begins to cool down the operation with the maximum refrigerating output to with the goods temperature decline fast to satisfy preset goods temperature range.
Referring to fig. 3, in an embodiment, the step of adjusting the frequency of the compressor of the air cooler according to the average ambient temperature of the warehouse includes steps S310 and S320.
And step S310, comparing and analyzing the average environment temperature of the storehouse with a preset storage temperature.
And step S320, when the average environment temperature of the warehouse is greater than the preset storage temperature, controlling a compressor of the air cooler to run at the maximum frequency until the average environment temperature of the warehouse is less than or equal to the preset storage temperature.
Specifically, the preset storage temperature is the optimal storage temperature corresponding to the goods. After the controller receives the ambient temperatures collected and sent by the ambient temperature collectors, the corresponding average ambient temperature of the storehouse is obtained by analyzing according to the ambient temperatures, and then the average ambient temperature of the storehouse and the preset storage temperature are compared and analyzed, so that whether the temperature inside the storehouse needs to be adjusted or not is determined. When the air outlet of air-cooler was nearer apart from the goods, probably makeed temperature data to descend rapidly to satisfying preset goods temperature, but the inside ambient temperature of storehouse changes little, also appears the average ambient temperature in storehouse and is greater than the condition of presetting the temperature of depositing, will need to continue to cool down the storehouse this moment and handle to satisfy the best storage demand of goods.
Similarly, the cooling control of the warehouse is realized by adjusting the operating frequency of the compressor of the air cooler, and in order to enable the temperature in the warehouse to quickly reach the temperature suitable for the optimal storage state of the goods, the controller can also control the compressor to operate at the maximum frequency. It should be noted that the preset storage temperature is not unique, and may be set differently for different types of goods and different user requirements.
It can be understood that, if the controller performs the comparative analysis on the average ambient temperature of the warehouse and the preset storage temperature, and in the operation of performing the comparative analysis on the temperature data and the preset cargo temperature range, the compressor is already controlled to operate at a high frequency to reduce the temperature data to meet the preset cargo temperature range, and then the compressor is only controlled to operate at the maximum frequency at this time. If the temperature data directly meets the preset cargo temperature range in the previous operation of carrying out comparison and analysis according to the temperature data and the preset cargo temperature range, the controller controls the compressor to start to operate at the maximum frequency.
Referring to fig. 3, in an embodiment, after the step S310, the method further includes a step S330.
And step S330, controlling a compressor of the air cooler to operate at a preset normal temperature frequency when the average environment temperature of the warehouse is less than or equal to a preset storage temperature.
Specifically, the preset normal temperature frequency is smaller than the maximum frequency. When the controller carries out comparative analysis according to the average environment temperature of the storehouse and the preset storage temperature, the condition that the average environment temperature of the storehouse is less than or equal to the preset storage temperature can also occur, at the moment, the current environment of the storehouse is represented to meet the storage requirement of goods, the necessity of continuously reducing the storage temperature in the storehouse is avoided, and therefore the compressor is controlled to operate at the preset normal temperature frequency and the current temperature is maintained.
Referring to fig. 4, in an embodiment, the step of adjusting the frequency of the compressor of the air cooler according to the average ambient temperature of the warehouse includes steps S340 and S350.
Step S340, comparing and analyzing the average environment temperature of the storehouse with a preset storage temperature range;
and step S350, when the average environment temperature of the warehouse is larger than the maximum value of the preset storage temperature range, controlling a compressor of the air cooler to run at the maximum frequency until the average environment temperature of the warehouse meets the preset storage temperature range.
Specifically, similar to the above-described embodiment, the optimum storage temperature of the goods is set to a range value in the present embodiment, and the optimum storage requirement of the goods can be satisfied as long as the average ambient temperature of the warehouse is within the range value. Therefore, the average environmental temperature of the warehouse obtained by analysis is compared and analyzed with the preset storage temperature range in the embodiment, and when the average environmental temperature of the warehouse is larger than the maximum value of the preset storage temperature range, the controller can realize the operation similar to the operation that the average environmental temperature of the warehouse is larger than the preset storage temperature, and the description is omitted.
Referring to fig. 4, in an embodiment, after the step S340, the method further includes a step S360.
And step S360, when the average ambient temperature of the warehouse meets the preset storage temperature range, controlling a compressor of the air cooler to operate at a preset normal temperature frequency.
Similarly, the preset normal temperature frequency is smaller than the maximum frequency. When the controller carries out comparative analysis according to the average environment temperature of the storehouse and the preset storage temperature range, the state that the average environment temperature of the storehouse meets the preset storage temperature range can also occur, and the condition that the average environment temperature of the storehouse meets the preset storage temperature range can also include the condition that the average environment temperature of the storehouse is between the preset storage temperature ranges and the condition that the average environment temperature of the storehouse is smaller than the minimum value of the preset storage temperature range. In both cases, it indicates that the current environment is not necessary to continue cooling, and at this time, the controller will perform the same operation as that in the above embodiment, in which the average ambient temperature of the warehouse is lower than the preset storage temperature, and details are not described here.
Further, in one embodiment, the step of reducing the operating frequency of the compressor of the air cooler comprises: and when the frequency of the compressor of the air cooler is the maximum frequency, reducing the frequency of the compressor to the preset normal temperature frequency.
Specifically, if the controller performs comparison analysis according to the temperature data and the corresponding preset cargo temperature range, the temperature data is greater than the maximum value of the preset cargo temperature range, so as to control the compressor to operate at the maximum frequency, and when the average environment temperature of the warehouse and the preset storage temperature are subsequently analyzed, the average environment temperature of the warehouse is less than or equal to the preset storage temperature, and at this time, the compressor should be in a state of operating at the maximum frequency. Therefore, the operation of the compressor of the time control refrigeration fan in the preset normal temperature frequency is as follows: the frequency of the compressor is controlled to be reduced to a preset normal temperature frequency, specifically, the frequency can be directly reduced to the preset normal temperature frequency at one time, and the frequency can also be fixed or regulated in a certain proportion.
If the controller carries out comparative analysis according to temperature data and the corresponding goods temperature range of predetermineeing, temperature data satisfies the goods temperature range of predetermineeing, but carries out the average ambient temperature in storehouse and predetermineeing when depositing the temperature and carry out comparative analysis, the average ambient temperature in storehouse is greater than predetermined and deposits the temperature, and the compressor can be in maximum frequency operating condition equally this moment. Therefore, the operation of the compressor of the time-controlled refrigeration fan running at the preset normal temperature frequency can also be as follows: the frequency of the compressor is controlled to be reduced to a preset normal temperature frequency, specifically, the frequency can be directly reduced to the preset normal temperature frequency at one time, and the frequency can also be fixed or regulated in a certain proportion.
According to the technical scheme, the storehouse temperature is adjusted in a sectional adjusting mode, and the temperature is adjusted once in a first stage of detecting that the storehouse is closed according to the temperature data of the goods and a preset goods temperature range until the temperature data meets the preset goods temperature range; under the state that the temperature data of goods satisfy preset goods temperature range, will carry out temperature regulation for the second time according to the average ambient temperature in storehouse and preserve the temperature (or preserve the temperature range) in advance, until satisfying the demand of depositing of goods, will control the compressor and keep presetting normal atmospheric temperature frequency operation always. And if the controller detects that the storehouse door is closed again, returning to the scheme for performing the staged storehouse temperature adjustment.
Further, in one embodiment, because the environment temperature collectors are uniformly arranged in the warehouse, different storage areas can be divided through the environment temperature collectors, the controller analyzes the average temperature data corresponding to each storage area and the corresponding relation between the cargo type and the optimal storage temperature, and can judge the cargo types suitable for storage in different storage areas.
According to the storehouse temperature control method, when the closing of the storehouse door is detected, firstly, comparison analysis is carried out according to the temperature data of the current storehouse storage goods and the preset goods temperature range, under the condition that the preset goods temperature range is met, analysis can be further carried out according to the temperature of the internal environment of the storehouse, then the compressor frequency of the air cooler is adjusted by combining the real-time average environment temperature of the storehouse, and the adjustment operation of the storage temperature of the goods in the storehouse is realized. Through the scheme, the temperature data of the goods stored in the storehouse and the average environment temperature of the storehouse can be combined to adjust the internal temperature of the storehouse, so that the environment temperature of the storehouse reaches the temperature suitable for storing the goods. Through linking up storehouse temperature regulation and actual storage goods, avoid appearing the too big or the condition of storing the damage of appearance of energy consumption, for carrying out temperature control's mode according to air-cooler air outlet temperature, humidity, effectively improve goods storage reliability.

It is understood that in one embodiment, the closing of the warehouse door may be achieved by the triggering device, that is, when the warehouse door is closed, the triggering device will obtain a triggering signal, and the controller 20 receives the triggering signal, that is, the closing of the warehouse door is indicated.
