Fig. 1 shows a schematic structural diagram of a multi-machine control system of a heat pump for food according to an embodiment of the present application, and as shown in fig. 1, the multi-machine control system of a heat pump for food according to the present embodiment includes a master controller 101 and a heat energy adjusting unit 102.
In this embodiment, the main controller 101 is also a central controller, and is connected to the thermal energy adjusting unit through a bus according to a predetermined connection mode of the control circuit. Therefore, when the master controller needs to send the control command, the control command can be sent uniformly through the bus, and the operation is convenient.
Specifically, each group of thermal energy conditioning units 102 includes a heat pump 1021 and a group of environment detection elements 1022, the heat pump 1021 is connected with the master controller 101 through a bus, and the heat pump 1021 in each group of thermal energy conditioning units 102 is connected with the environment detection elements 1022. The multiple sets of thermal energy regulating units 102 of the present embodiment may be disposed in a relatively closed space, such as a sample room dedicated to baking food, and generally, for mass production of food, the sample room space is large enough to divide the sample room into multiple regions with the same size and different positions, and generally, each region does not overlap with another region. As an application scenario of this embodiment, a sample room for baking potato chips is provided, and the sample room is divided into 10 regulation and control areas according to actual requirements, and then ten sets of thermal energy regulation units 102 need to be arranged in the regulation and control areas in a one-to-one correspondence manner. The heat pump 1021 in the thermal energy conditioning unit 102 may be installed above the corresponding control area. A user may input a start-up command through the main controller 101, and the main controller 101 transmits the start-up command to each heat pump 1021 through the bus. In this embodiment, the heat pump 1021 includes a compressor, a fan, an adjusting valve, and the like, the heat pump 1021 receives a start-up instruction, the start-up instruction includes a control parameter, the control parameter is identified and stored in the heat pump 1021 as a preset control parameter, and a parameter value of each internal component of the heat pump 1021 is adjusted according to the control parameter to output a matched environmental energy.
The environmental energy in this embodiment is based on factors such as temperature, humidity, and air volume output according to the adjustment of each component in the heat pump in the control parameters. In the embodiment of the present application, each group of the thermal energy regulating units 102 is installed in a corresponding control area, and the environment detecting element 1022 is configured to detect an environment parameter of the corresponding control area, send the environment parameter to the heat pump 1021, and forward the environment parameter to the master controller 1022 through the heat pump 1021. In the embodiment of the present application, the environment detection element and the heat pump may be connected by a wired connection or a wireless connection, wherein in the case of a wireless connection, in order to ensure that a group of environment detection elements 1022 corresponds to one heat pump 1021, a pairing code may be allocated to the heat pump 1021 and the environment detection elements 1022, the pairing code may be used by the heat pump 1021 and the environment detection elements 1022 which are matched with each other, when the environment detection elements 1022 send detected environment parameters, the pairing code is carried, so that the heat pump 1021 detects whether the detected environment parameters are environment parameters required by itself, when the detected environment parameters are environment parameters corresponding to itself, the environment parameters are saved and subsequent operations are executed, when the detected environment parameters are environment parameters which do not correspond to itself, the environment parameters are discarded, and an error signal may be returned to the environment detection elements. Different identification codes can be respectively allocated to the heat pump 1021 and the environment detection element 1022, the identification codes have uniqueness, and at the moment, the identification codes of the heat pump 1021 and the environment detection element 1022 in the same thermal energy regulation unit 102 need to be bound with each other to form a corresponding relationship so as to facilitate subsequent identification and signal matching. In the preferred embodiment of the present invention, the heat pump 1021 and the environmental detection element 1022 in the same thermal energy conditioning unit 102 are connected by wire, so that no additional identification code is required, and the development cost and resource cost are reduced. Because the same group of thermal energy regulating units 102 are located in the corresponding regulating and controlling intervals, the installation distance between the heat pump 1021 and the environment detecting element 1022 is not too far, the heat pump 1021 and the environment detecting element 1022 are connected by a wire, so that the identification and the correspondence between the two parties are facilitated, and the accuracy of data transmission is feasible and convenient.
Further, the main controller 101 is configured to, according to comparison of environmental parameters detected by each set of the environmental detection elements 1022, obtain an environmental correction parameter when detecting that the environmental parameter detected by any one set of the environmental detection elements 1022 is abnormal, and output the environmental correction parameter to the heat pump 1021 corresponding to the environmental detection element; the heat pump 1021 is configured to output environmental energy, compare the environmental parameter from the environmental detection element with a preset control parameter, and adjust the output environmental energy when the environmental parameter is inconsistent with the preset control parameter or when receiving an environmental correction parameter from the main controller 101.
Specifically, the thermal energy adjusting unit 102 plays a role of adjusting and controlling the environment of the corresponding adjusting and controlling area, and is particularly used for controlling the corresponding heat in the application as the drying place. For example, the air output of the fan in the fan is adjusted, and certain influence is generated on the temperature in the whole regulation and control area, so that the detection parameters of the environment detection element are influenced. As an application, a user clicks a start button through the main controller 101, and inputs control parameters including adjustment parameter values corresponding to different components such as a fan of the heat pump itself, together, to form a start instruction. When the heat pump 1021 receives the startup instruction, the startup instruction is firstly analyzed to obtain the adjustment parameter values of different components, and the different components are respectively adjusted in sequence. When the parameter value of each part is different, the finally output environmental energy is different. And then detecting the environmental parameters in the regulation and control area through an environmental detection element. The control parameters input in advance may include specific values of the environmental parameters in addition to the adjustment parameter values, or a comparison table is preset, and the comparison table has a corresponding relationship between the adjustment parameter values and the specific values of the environmental parameters. When the environment detecting element 1022 detects the environment parameter, a specific value of the environment parameter is obtained, and the specific value of the environment parameter is compared with the specific value of the environment parameter corresponding to the adjustment parameter value, so as to determine whether the values are consistent. If the difference is not the same, the control parameter is corrected. In addition, the main controller receives the environmental parameters detected by the environmental detection elements 1022 in different control areas through the plurality of heat pumps 1021, for example, there are five environmental detection elements 1022, the preset control parameters of the control areas corresponding to the five environmental detection elements 1022 are the same, and the specific values of the environmental parameters detected by the five environmental detection elements 1022 are a, b, c, d, e, comparing whether the above a, b, c, d, e are the same, if b, c, d, e are the same, and a is different from b, c, d, e, it indicates that a is different, that is, the heat pumps 1021 in the same group of the environmental detection elements for detecting a need to be adjusted, and the control parameters are specifically adjusted.
As shown in fig. 2, another multi-machine control system of heat pump for food is further provided according to an embodiment of the present invention, in this embodiment, each set of environment detection elements 2022 includes at least one temperature sensor 203 and at least one humidity sensor 204, and the environment parameters detected by the environment detection environment include a temperature parameter detected by the temperature sensor 203 and a humidity parameter detected by the humidity sensor 204. The temperature sensor 203 and the humidity sensor 204 are both connected with the heat pump 2021.
In the case of this embodiment, the environmental parameters detected by each set of the environment detecting elements 2022 include a temperature a and a humidity b, and when the environment detecting elements 2022 correspond to different control areas, the parameters of the temperature and the humidity need to be compared respectively, so as to adjust the components of the heat pump 2021 that have the function of adjusting the temperature or the humidity when necessary.
Taking an example that the set of environment detecting elements 2022 includes a temperature sensor 203 and includes a humidity sensor 204, the environment parameters collected by the environment detecting elements 2022 include temperature and humidity, where the specific value of the temperature is a and the specific value of the humidity is b. The heat pump 2021 verifies its own preset control parameters according to a and b. A parameter energy comparison table may be stored in advance, and the parameter energy comparison table records a correspondence between the environmental parameter and the adjustment value of each component in the heat pump 2021, and when the environmental parameters a and b are different from the preset control parameter, the adjustment value of each layout may be obtained from the parameter energy comparison table according to the values of a and b, for example, when the current fan is turned on at the third gear, and according to the parameter energy comparison table, the fan corresponds to the second gear, the fan is adjusted from the third gear to the second gear. The parameter energy comparison table is integrated by a plurality of historical data in advance.
Taking the example that the set of environment detecting elements 2022 includes 3 temperature sensors 203 and 2 humidity sensors 204, the environment parameters collected by the environment detecting elements 2022 also include temperature and humidity, the specific values of the temperature are a1, a2 and a3, and the specific values of the humidity are b1 and b 2. At this time, the heat pump 2021 and the main controller 201 need to perform the comparison detection on the preset control parameters thereof by considering the above five environmental parameters at the same time. In this case, the preset control parameter may include three specific temperature values respectively corresponding to the three temperature sensors and 2 specific humidity values respectively corresponding to the two humidity sensors, and in another example, the preset control parameter may have only one specific temperature value and one specific humidity value, and the average values of the temperature and the humidity in the environmental parameter may be respectively obtained as the reference for comparison with the specific values in the preset control parameter.

And the operable display 301 is connected with the main controller 302, and the operable display screen 301 is used for receiving a starting-up command input by a user and sending the starting-up command to the heat pump 3031 of each group of thermal energy regulating units 303 through the main controller 302. The operable display 301, such as a touch screen, may facilitate providing a user with an input interface and a means for viewing the condition of the regulatory region in real time.
Fig. 4 is a flowchart of a multi-machine control method for a heat pump for food according to an embodiment of the present application, where the multi-machine control method for a heat pump for food can be executed by a multi-machine control device for a heat pump for food, and the multi-machine control device for a heat pump for food can be implemented by hardware and/or software and is integrated in a computer device.
The following description will be given taking as an example a method for executing a multi-machine control of a heat pump for food by a multi-machine control device for a heat pump for food. Referring to fig. 4, the multi-machine control method of the heat pump for food comprises the following steps:
401: and responding to a starting-up instruction input by a user, and controlling the output of the environmental energy based on preset control parameters contained in the starting-up instruction.
The present embodiment describes the control flow based on the angle of the heat pump in the thermal energy adjusting unit. The heat pump receives the starting instruction forwarded by the main controller and responds to the starting instruction. The response is that the heat pump performs the startup action. The starting instruction carries control parameters set by a user, the control parameters comprise specific values of all components in the heat pump, and all the components of the heat pump can be adjusted based on the specific values, so that the control on the output of the environmental energy is achieved. During the continuous operation of the heat pump, the user can readjust the control parameters.
402: and receiving the environmental parameters from the environmental detection element, comparing the environmental parameters with preset control parameters, and adjusting the output of the environmental energy according to the environmental parameters when the environmental parameters are inconsistent with the preset control parameters.
After the starting instruction is issued, the heat pump is started to work, the environment detection element is also started to work, environment monitoring is carried out on the responsible regulation and control area, and environment parameters are collected. The environment detecting element sends the acquired environment parameters to the heat pump, and the heat pump plays a role in monitoring the actual energy output of the heat pump according to the environment detecting element. The environment detection element can acquire the environment parameters once every set time or in real time. When the environmental parameter is inconsistent with the preset control parameter, the preset control parameter corresponds to a specific value, the acquired environmental parameter also corresponds to a specific value, the two specific values are compared to see whether the difference exists, and the output of the environmental energy is adjusted if the difference exists. It should be noted that the difference in this embodiment may simply mean that there is a difference between two specific values, or may mean that the difference is calculated only when the difference reaches a certain threshold.
403: and receiving the environment correction parameters from the master controller, and adjusting the output of the environment energy according to the environment correction parameters.
The environment detection element not only provides the heat pump with the functions of self-monitoring, repairing and adjusting, but also provides the main controller with supervision on the whole working area according to the local regulation and control area. The main controller receives the environmental parameters detected by each group of environmental detection elements, compares the environmental parameters with each group of environmental parameters and judges whether any one environmental parameter is abnormal or not. In this embodiment, the manner of determining the abnormality includes setting a threshold, and determining that the abnormality occurs when the specific value satisfies the threshold (including being greater than or less than the threshold), or comparing the environmental parameter of a certain group with the environmental parameters of other groups, and there is a difference. If the environmental parameters detected by a group of environmental detection elements are abnormal and far lower than normal values, the heat pump corresponding to the regulation and control area is indicated to have problems, and the environmental energy output of the heat pump is regulated. Firstly, an environment correction parameter is obtained, wherein the environment correction parameter is a numerical value used for making up the abnormity, so that after the heat pump is corrected by the environment correction parameter, the environment parameter of the regulation and control area can theoretically accord with a normal value after a period of time.
Preferably, the environmental parameters include a temperature parameter and a humidity parameter, and the preset control parameters include a temperature control parameter and a humidity control parameter.

Similarly, the adjustment of the humidity control parameters is changed according to the specific adjustment values of different components, so that the corresponding preset control parameters are actually changed.
