Description

Technical Field

[0001] The present invention relates to the field of refrigeration, in particular to a multi-unit hybrid refrigeration system and a mushroom cultivation room. Background Art

[0002] During the process of using mushroom air conditioners in a mushroom house, it is necessary to precisely control the temperature of the mushroom house. The suitable temperature required by mushrooms in each growth cycle is different. If the heat generation of a certain mushroom is large, causing the temperature near this point to exceed the suitable growth temperature of the mushroom itself, it will affect the normal growth of the mushroom, such as causing the loss of nutritional components of the mushroom, and seriously leading to the death of the mushroom, resulting in economic losses.

[0003] There are multiple air conditioners in the mushroom house. In traditional temperature recognition, one air conditioner controls the temperature of an area near itself. During the use of the air conditioner, affected by the compressor running for six minutes and stopping for three minutes, when controlling the temperature of the mushroom house, if the compressor stops for some reason (such as temperature point shutdown, etc.), it takes at least three minutes for the compressor to start normally. During this process, if the temperature of a certain area in the mushroom house does not meet the temperature required for the current growth of the mushroom due to some special reasons (such as excessive heat generation of the mushroom, human problems, etc.), it will affect the mushroom and cause economic losses.

[0004] For example: The current suitable temperature for mushroom growth is 6°C. The air conditioner has cooled the room temperature to about 6°C and starts temperature point shutdown. Just at this time, the temperature of a certain mushroom rises to 9°C. At this time, the air conditioner has just stopped and the compressor cannot be immediately turned on. If the mushroom cannot be cooled in time at this time, it will affect the growth of the mushroom, thus causing losses to the user. Summary of the Invention

[0005] Aiming at the problem in the prior art that when controlling the temperature of the mushroom house, the compressor stops for some reason, resulting in the inability to cool the mushrooms in time, affecting the growth of the mushrooms and causing losses to the user, the present invention proposes a multi-unit hybrid refrigeration system and a mushroom cultivation room.

[0006] The technical solution of the present invention is to propose a multi-unit hybrid refrigeration system, including: including a plurality of refrigeration intervals, and each of the refrigeration intervals is correspondingly provided with a refrigeration unit. It is characterized in that the multi-unit hybrid refrigeration system further includes a controller, and the controller at least has:

[0007] A reader-writer, which is used to receive and update the refrigeration information in the refrigeration interval;

[0008] A processor, which is used to communicate with the reader-writer to obtain the refrigeration information and adjust the operating state of the refrigeration unit according to the refrigeration information;

[0009] When refrigeration is abnormal in any of the refrigeration intervals, the processor controls the refrigeration units outside the refrigeration interval with abnormal refrigeration to perform cross-region refrigeration.

[0010] Furthermore, the refrigeration units are divided into a first refrigeration unit and a second refrigeration unit according to their refrigeration capacities;

[0011] and the first refrigeration unit has refrigeration capacity, while the second refrigeration unit does not have refrigeration capacity;

[0012] All the refrigeration units operate according to a preset control strategy and switch between the first refrigeration unit and the second refrigeration unit under the control of the preset control strategy;

[0013] The refrigeration information includes the division information of the refrigeration units.

[0014] Furthermore, the refrigeration interval is divided into a first refrigeration interval and a second refrigeration interval according to its refrigeration demand;

[0015] and the first refrigeration interval has a refrigeration demand, while the second refrigeration interval does not have a refrigeration demand;

[0016] The refrigeration interval switches between the first refrigeration interval and the second refrigeration interval according to its ambient temperature;

[0017] The refrigeration information further includes the division information of the refrigeration interval.

[0018] Furthermore, when the refrigeration interval is divided into the first refrigeration interval and the corresponding refrigeration unit is divided into the second refrigeration unit, the refrigeration interval is determined to be abnormally refrigerated.

[0019] Furthermore, radio frequency communication technology is adopted between the reader-writer and the processor;

[0020] and when refrigeration is abnormal in any of the refrigeration intervals, the processor can obtain the first refrigeration unit closest to the refrigeration interval with abnormal refrigeration and perform cross-region refrigeration through the first refrigeration unit.

[0021]

[0022] Furthermore, the preset control strategy is a control strategy of running for six and stopping for three.

[0023] Furthermore, the control strategy for cross-region refrigeration through the refrigeration unit at least includes: increasing the fan speed of the refrigeration unit and the operating frequency of the compressor.

[0024] Furthermore, the controller at least further includes:

[0025] a memory unit for storing the refrigeration information;

[0026] A driving chip is connected to the processor and is used to regulate the operating state of the refrigeration unit under the control of the processor.

[0027] Furthermore, when cross-region refrigeration is not carried out, the reader updates the refrigeration information at a preset time;

[0028] After cross-region refrigeration is carried out, the reader updates the refrigeration information each time cross-region refrigeration is completed.

[0029] The present invention also provides a mushroom cultivation room which has the above multi-unit hybrid refrigeration system.

[0030] Compared with the prior art, the present invention has at least the following beneficial effects:

[0031] The present invention utilizes radio frequency communication technology to receive and update the refrigeration information in each refrigeration area in real time. At the same time, when refrigeration anomalies are detected, cross-region refrigeration is carried out on the refrigeration unit with refrigeration anomalies by the refrigeration units outside the refrigeration area, reducing the temperature of the mushrooms and avoiding losses caused by temperature problems during the mushroom cultivation process.

[0034] Figure 2 It is the schematic diagram of the composition of the controller of the present invention;

[0035] Figure 3 It is the overall control flowchart of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the following further describes the present invention in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] Accordingly, a feature pointed out in this specification is used to illustrate one of the features of an embodiment of the present invention, rather than implying that each embodiment of the present invention must have the illustrated feature. In addition, it should be noted that this specification describes many features. Although some features may be combined to show possible system designs, these features can also be used in other combinations that are not explicitly described. Accordingly, unless otherwise stated, the illustrated combinations are not intended to be limiting.

[0038] The principle and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0039] During the use of the air conditioner, affected by the compressor running for six minutes and stopping for three minutes (running in a cycle of starting for six minutes and stopping for three minutes), when controlling the temperature in the mushroom house, when the compressor stops for some reason (such as stopping due to the temperature point), it takes at least three minutes for the compressor to start normally. During this process, if the temperature in a certain area of the mushroom house does not meet the requirements for the current growth of the mushrooms due to some special reasons (such as excessive heat generation by the mushrooms, human problems, etc.), it will affect the growth of the mushrooms and cause losses to the users.

[0040] To address the above problems, the idea of the present invention is to use radio frequency communication technology to obtain the refrigeration information in each refrigeration area. At the same time, when refrigeration is abnormal in a certain refrigeration area, find the nearest refrigeration unit to refrigerate for this refrigeration area, so as to avoid the temperature in this refrigeration area being too high and affecting the growth of the mushrooms.

[0041] Specifically, the multi-unit hybrid refrigeration system proposed by the present invention includes multiple refrigeration areas, and each refrigeration area is matched with a refrigeration unit.

[0042] Among them, the multi-unit hybrid refrigeration system proposed by the present invention further includes a controller, which at least has:

[0043] A reader-writer, which is used to receive and update the refrigeration information in the refrigeration area;

[0044] A processor, which is used to communicate with the reader-writer to obtain the refrigeration information and adjust the operating state of the refrigeration unit according to the refrigeration information;

[0045] When refrigeration is abnormal in any refrigeration area, the processor controls the refrigeration units outside the refrigeration area with abnormal refrigeration to perform cross-area refrigeration.

[0046] Its working process is as follows. Under normal working conditions, each refrigeration area is equipped with a refrigeration unit, which refrigerates through a control strategy of running for six minutes and stopping for three minutes. At the same time, the reader receives and updates the refrigeration information in each refrigeration area in real time. When refrigeration is abnormal in a certain refrigeration area, the reader can receive and update this refrigeration information. At this time, the processor controls the nearest normal refrigeration unit to this refrigeration area to perform cross-area refrigeration for this instruction area, so that the temperature in this refrigeration area decreases, thereby avoiding the impact on the growth of mushrooms due to temperature problems.

[0047] In summary, through the above design method, the present invention can avoid losses caused by the inability to refrigerate when the compressor stops and the temperature in the mushroom house is abnormal.

[0048] Specifically, from the factors affecting the growth of mushrooms mentioned above, the situations where the refrigeration area will affect the mushrooms are as follows: 1. At this time, the temperature in this refrigeration area is abnormal (too high and not suitable for the growth of mushrooms); 2. At this time, the compressor is in a shutdown state and cannot work.

[0049] In response to the above two situations, the present invention divides the working conditions of the refrigeration units and the refrigeration areas respectively, so as to facilitate the determination of whether the current refrigeration area has abnormal refrigeration.

[0050] Specifically, in the present invention, the refrigeration units are divided into a first refrigeration unit and a second refrigeration unit according to their refrigeration capacities;

[0051] And the first refrigeration unit has refrigeration capacity, while the second refrigeration unit does not have refrigeration capacity;

[0052] Among them, all refrigeration units operate according to a preset control strategy and switch between the first refrigeration unit and the second refrigeration unit under the control of the preset control strategy.

[0053] The above refrigeration information includes the division information of the refrigeration units.

[0054] The preset control strategy pointed out in the present invention is also the six-on-three-off control strategy pointed out above, that is, it is turned off for three minutes every six minutes of operation. Under this strategy, within each control cycle, the refrigeration unit will have a six-minute opening time and a three-minute closing time, that is, the refrigeration unit will switch between the first refrigeration unit and the second refrigeration unit.

[0055] The present invention uses radio frequency communication technology for communication, and can store the above information in RFID information (the information transmitted by radio frequency communication technology) to facilitate the judgment of abnormal refrigeration.

[0056] On the other hand, in the present invention, the refrigeration areas are divided into a first refrigeration area and a second refrigeration area according to their refrigeration requirements;

[0057] And the first refrigeration zone has a refrigeration demand, while the second refrigeration zone has no refrigeration demand;

[0058] Here, the refrigeration zone switches between the first refrigeration zone and the second refrigeration zone according to its ambient temperature;

[0059] The above refrigeration information also includes the division information of the refrigeration zone.

[0060] Here, since the mushrooms are only affected at higher temperatures, for example, when the temperature is 9°C, it will affect the growth of the mushrooms. However, with the traditional six-on-three-off control strategy, generally it will not have a great impact on the temperature of the currently refrigerated refrigeration zone, and the factors of its abnormal temperature are mostly other principles. Therefore, in the above judgment of refrigeration abnormality, it is necessary to judge whether the current refrigeration zone is in the first refrigeration zone or the second refrigeration zone according to the ambient temperature in the refrigeration zone. The specific judgment logic is that when the temperature in the current refrigeration zone is higher than the preset temperature, the current refrigeration zone has a refrigeration demand; on the contrary, when the temperature in the current refrigeration zone is lower than the preset temperature, the current refrigeration zone has no refrigeration demand.

[0061] In the present invention, radio frequency communication technology is used for communication, and the above information can be stored in RFID information (the information transmitted by radio frequency communication technology) to facilitate the judgment of refrigeration abnormality.

[0062] After obtaining the division information of the above refrigeration unit and the division information of the refrigeration zone, it is possible to determine whether the current refrigeration zone has refrigeration abnormality.

[0063] According to the foregoing, the situations that affect the mushrooms are: 1. At this time, the temperature in the refrigeration zone is abnormal (too high, not suitable for the growth of mushrooms); 2. At this time, the compressor is in a shutdown state and cannot work. It can be determined that when the current refrigeration zone is the first refrigeration zone and the refrigeration unit matched therein is the second refrigeration unit, the above refrigeration zone is determined to have refrigeration abnormality, and at this time, cross-zone refrigeration is required.

[0064] As shown in the following table, radio frequency communication technology is used for communication in the present invention, and its RFID information has:

[0065]

[0066] Here, for the refrigeration capacity of the refrigeration unit, when its output is 1, it indicates that the refrigeration unit has refrigeration capacity at this time and is classified as the first refrigeration unit; when its output is 0, it indicates that the refrigeration unit has no refrigeration capacity at this time and is classified as the second refrigeration unit;

[0067] For the refrigeration demand of the refrigeration interval, when its output is 1, it indicates that there is a refrigeration demand in the refrigeration interval at this time, and it is divided into the first refrigeration interval. When its output is 0, it indicates that there is no refrigeration demand for the refrigeration unit at this time, and it is divided into the second refrigeration interval.

[0068] In the present invention, through radio frequency communication technology, when the refrigeration capacity of the refrigeration unit is 0 and the refrigeration demand of the refrigeration interval is 1, it can be determined that the refrigeration is abnormal at this time and cross-region refrigeration is required.

[0069] In the present invention, radio frequency communication technology is adopted between the reader-writer and the processor. And when the refrigeration is abnormal in any refrigeration interval, the processor can obtain the first refrigeration unit closest to the refrigeration interval with abnormal refrigeration, and perform cross-region refrigeration through this first refrigeration unit.

[0070] Among them, the reader-writer can write the refrigeration capacity of the refrigeration units in all refrigeration intervals, and is matched with the refrigeration intervals one by one. When it is determined that the refrigeration is abnormal in a certain refrigeration interval, it is sent out through radio frequency communication technology. The reader-writer in each refrigeration unit receives the corresponding RFIO information. After the nearest first refrigeration unit obtains the RFIO information that needs cross-region refrigeration, it starts cross-region refrigeration to avoid the influence of temperature on the growth of mushrooms.

[0071] Here, the control strategy for cross-region refrigeration at least includes: increasing the fan speed of the refrigeration unit and the operating frequency of the compressor.

[0072] It should be noted that when cross-region refrigeration is performed on other refrigeration intervals by the current refrigeration unit, it will not affect the growth of mushrooms in the refrigeration interval where the refrigeration unit is located. Taking refrigeration interval 1, refrigeration interval 2, refrigeration unit a (set in refrigeration interval 1), and refrigeration unit b (set in refrigeration interval 2) as examples for illustration. Here, both refrigeration interval 1 and refrigeration interval 2 are the first refrigeration intervals, refrigeration unit a is the first refrigeration unit, and refrigeration unit b is the second refrigeration unit. At this time, due to the too high temperature in refrigeration interval 2 and there is a refrigeration demand, but the corresponding refrigeration unit b has no refrigeration capacity. At this time, cross-region refrigeration needs to be performed through other refrigeration units. Here, refrigeration unit a is the nearest first refrigeration unit. At this time, by increasing the fan speed in refrigeration unit 1 and the operating frequency of the compressor, the refrigeration efficiency of refrigeration unit 1 can be improved, but it will not affect the final temperature reduced by refrigeration unit 1. For example, the time required for refrigeration unit 1 to reduce the temperature in refrigeration interval 1 by 1 degree Celsius was 10 minutes before. After the above adjustment, the required time becomes 5 minutes. It only increases the time for refrigeration unit 1 to reduce the refrigeration interval, and will not affect the final refrigeration temperature. In addition, when applied in the mushroom house, its lower temperature will not affect the growth of mushrooms. Therefore, through the above scheme, only the temperature in refrigeration interval 2 will be reduced, and refrigeration interval 1 will not be affected.

[0073] Further, the controller proposed in the present invention at least further includes:

[0074] A memory unit for storing refrigeration information;

[0075] A driving chip, which is connected to the processor and is used to control the operating state of the refrigeration unit under the control of the processor.

[0076] As Figure 2 shown, it is a schematic diagram of the composition of the controller in the present invention, which at least has an RFID reader / writer (i.e., the reader / writer mentioned above), a microprocessor (i.e., the processor mentioned above), a memory unit, and a driving chip.

[0077] Here, the RFID reader / writer is mainly used to receive and update RFID information and control the sending frequency of the radio frequency. The microprocessor communicates with the RFID reader / writer and is used to execute the overall control of the unit. The microprocessor communicates with the RFID reader / writer through a serial port. The driving chip is used to drive loads such as fans, water pumps, compressors, etc. Here, because the current of the microprocessor is small and insufficient to drive the load, it is necessary to drive through the driving chip. The memory unit is mainly used to store RFID information for subsequent information reading.

[0078] Here, when cross-region refrigeration is not carried out, the above-mentioned reader / writer updates the refrigeration information at a preset time to achieve real-time monitoring of the refrigeration unit and the refrigeration area;

[0079] After cross-region refrigeration is carried out, the reader / writer updates the refrigeration information after each cross-region refrigeration is completed.

[0080] Please refer to Figure 1 , which is the power-on process of the refrigeration unit in the present invention. After the refrigeration unit is powered on, it communicates within a fixed radio frequency range for 1 minute. At this time, each reader / writer only obtains the refrigeration information of the refrigeration area where it is located, and then updates the refrigeration information in the refrigeration area. Finally, it increases the radio frequency range to read all refrigeration information. After the reader / writer receives the refrigeration information of other refrigeration areas, it first judges whether it is the refrigeration information of its own refrigeration area. If not, and there is a refrigeration demand, it turns on the refrigeration unit in its own refrigeration area to carry out cross-region refrigeration.

[0081] Please refer to Figure 3, which is the overall control flowchart of the present invention. When the refrigeration unit is powered on, its RFID information is updated, and at the same time, after obtaining the RFID information in all other refrigeration zones, the reader starts to analyze the received RFID information. First, it determines whether it is the RFID information in its own refrigeration zone (i.e., the temperature points in its own area in the flowchart). If it is, then the RFID information at this time is updated according to whether refrigeration is required (i.e., whether temperature control is required in the flowchart) and whether the refrigeration unit can perform refrigeration (i.e., whether the compressor can be immediately started in the flowchart), and then the reception and update of RFID information continue;

[0082] If the RFID information in other refrigeration zones is received, it first determines whether cross-zone refrigeration is required. If so, it then determines whether the refrigeration unit in the current refrigeration zone can perform refrigeration (i.e., whether the compressor can be immediately started in the flowchart). If it can, cross-zone refrigeration is performed through this command unit. Otherwise, the demand is published through the wired network and the RFID transmission power is increased to obtain other refrigeration units that can perform cross-zone refrigeration.

[0083] In summary, the present invention uses radio frequency communication technology to receive and update the refrigeration information in each refrigeration zone in real time. At the same time, when refrigeration anomalies are detected, cross-zone refrigeration is performed on the refrigeration unit with refrigeration anomalies by the refrigeration units outside the refrigeration zone to reduce the temperature of the mushrooms and avoid losses caused by temperature problems during the mushroom cultivation process.

[0084] The present invention also proposes a mushroom cultivation room, which has the above multi-unit hybrid refrigeration system.

[0085] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
