[0063] In order to make the purpose and features of the present invention more obvious and easy to understand, the technical solution of the present invention is described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in different forms and should not be limited to the described embodiments. In addition, it should be noted that each box in the block diagram and / or flow chart herein, and the combination of boxes in the block diagram and / or flow chart can be implemented by a dedicated hardware-based system that performs a specified function or action, or can be implemented by a combination of dedicated hardware and computer program instructions. It is well known to those skilled in the art that implementation by hardware, implementation by software, and implementation by a combination of software and hardware are all equivalent.

[0064] As described in the background technology, in the prior art, when a refrigeration system is produced, upgraded or fails, if the model of the motor or compressor changes, the corresponding controller needs to be replaced. For example, if the motor in the refrigeration system that was manufactured in 2011 is upgraded to a new specification motor that was manufactured in 2014, the corresponding controller needs to be replaced, which increases the maintenance cost and requires a large number of controllers to be stocked, which is inconvenient to manage.

[0065] To this end, the present invention provides a refrigeration system 10 with a more versatile controller, see Figure 1 and Figure 2 The refrigeration system 10 is provided with a system characteristic tag storing system information.

[0066] Specifically, the system information includes:

[0067] First, system information, including system number, such as system A, system B, etc.

[0068] The second system information includes the model number combination of the adapted controller, motor and compressor. For example, in system A, motor a, compressor a and controller m are adapted; in system B, motor b, compressor b and controller m are adapted...

[0069] The third system information includes the driving parameters of the adapted controller for the electronic component group. For example, the driving parameters of the controller m for the electronic component group in system A are z1. Specifically, z1 includes cooling capacity 3500w, heating and cooling, and capillary. The driving parameters of the controller m for the electronic component group in system B are z2. Specifically, z1 includes the cooling capacity 3500w, heating and cooling, and expansion valve.

[0070] The refrigeration system comprises:

[0071] The electronic component group 104 includes, specifically, the refrigeration capacity setting, cooling / warming / cooling selection, capillary tube / expansion valve selection, four-way valve setting and other electronic component settings.

[0072] The motor 101 is provided with a motor characteristic tag storing motor information.

[0073] Specifically, the motor information includes:

[0074] The first motor information includes the motor model number, such as motor a, motor b, etc.

[0075] The second motor information includes the driving parameters of the motor 101 by the controller 103 , for example, the driving parameter of the motor a is x1; the driving parameter of the motor b is x2 . . .

[0076] The compressor 102 is provided with a compressor characteristic tag storing compressor information.

[0077] Specifically, the compressor information includes:

[0078] The first compressor information includes the compressor model number, such as compressor a, compressor b...

[0079] The second compressor information includes the driving parameters of the controller 103 for the compressor 102, for example, the driving parameter of the compressor a is y1; the driving parameter of the compressor b is y2... The controller 103 is used to drive the motor 101 and the compressor 102. The controller 103 is provided with a controller feature tag 1032 storing the controller information. Specifically, the controller information includes the controller model number, for example, controller m, controller n...

[0080] In addition, the controller also includes an Internet of Things module 1031, which is used to read system feature tags, motor feature tags, compressor feature tags and controller feature tags to obtain system information, motor information, compressor information and controller information. If the motor information, compressor information and controller information match the system information, the controller's drive parameters for the electronic component group, the motor and the compressor are modified accordingly according to the system information, motor information, compressor information and controller information.

[0081] In this embodiment, by setting the Internet of Things module 1031 on the controller 103, one controller can be adapted to a variety of electronic component groups, motors and compressor combinations. For example, in system A, controller m can drive motor a and compressor a, but in system B, controller m can also drive motor b and compressor b as long as the drive parameters are modified accordingly, thereby improving the universal standardization of the controller, reducing the types of controllers, and reducing the management costs and stocking costs in procurement, logistics, production, and maintenance.

[0082] Furthermore, the refrigeration system further includes a network server 105 for storing refrigeration system information formed by various adapted system information, motor information, compressor information and controller information in different arrangements and combinations. Specifically, the network server 105 can be an Internet of Things terminal such as a computer, a mobile phone, a PLC, a customized handheld terminal or a cloud server.

[0083] Furthermore, the Internet of Things module 1031 is also used to send a matching request to the network server 105 when the motor information, compressor information and controller information do not match the system information, and the network server 105 queries the refrigeration system information that matches the system information, motor information, compressor information and controller information.

[0084] Furthermore, the Internet of Things module 1031 is also used to determine whether a matching success signal is received after sending a matching request to the network server 105; if a matching success signal is received, the controller modifies the driving parameters of the electronic component group, the motor and the compressor according to the matching success signal; if no matching success signal is received, the matching fails and a fault message is issued.

[0085] Furthermore, the network server 105 is specifically used to: read the system feature tag, the motor feature tag, the compressor feature tag and the controller feature tag to obtain the system information, the motor information, the compressor information and the controller information; query whether there is refrigeration system information that matches the system information, the motor information, the compressor information and the controller information; if so, obtain the driving parameters of the controller for the electronic component group, the motor and the compressor in the matching refrigeration system information, and send a matching success signal to the Internet of Things module; if not, feedback the unmatched items.

[0086] It should be noted that the data of the network server 105 can be maintained, updated and supplemented with refrigeration system information, and the database can be downloaded offline.

[0087] In addition, this embodiment also provides a self-matching method for a refrigeration system, see Figure 3 , including the following steps:

[0088] Step S100, the Internet of Things module reads the system feature tag, the motor feature tag, the compressor feature tag, and the controller feature tag to obtain system information, motor information, compressor information, and controller information;

[0089] Determine whether the motor information, compressor information, and controller information match the system information:

[0090] If they match, step S200 is executed to modify the driving parameters of the controller for the electronic component group, the motor and the compressor according to the system information, the motor information and the compressor information.

[0091] For example, the first system information of the current refrigeration system is obtained as system A, the second information is the adaptation of motor a, compressor a and controller m in system A, and the third system information is that the driving parameter of controller m for the electronic component group is z1; the first motor information in the motor information is motor a, and the second motor information is that the driving parameter of motor a is x1; the first motor information in the compressor information is compressor a, and the second motor information is that the driving parameter of compressor a is y1; the controller information is controller m, then it is determined that the motor information, compressor information and controller information match the system information, and then the driving parameters of the controller are modified, and its driving parameters for the electronic component group are modified to z1, the driving parameters of the motor are modified to x1, and the driving parameters of the compressor are modified to y1.

[0092] If there is no match, step S300 is executed to send a matching request to the network server, and the network server queries for refrigeration system information that matches the system information, motor information, compressor information, and controller information.

[0093] For example, it is learned that in the system information of the current refrigeration system, the first system information is system A, the second information is the adaptation of motor a, compressor a and controller m in system A, and the third system information is that the driving parameter of the electronic component group of controller m in system A is z1; the first motor information in the motor information is motor b, and the second motor information is that the driving parameter of motor b is x2; the first motor information in the compressor information is compressor a, and the second motor information is that the driving parameter of compressor a is y1; the controller information is controller m, then it is determined that the motor information, compressor information and controller information do not match the system information, and then a matching request is sent to the network server, and the network server queries the refrigeration system information that matches the system information, motor information, compressor information and controller information.

[0094] Furthermore, after sending a matching request to the network server, the method further includes:

[0095] Determine whether a matching success signal is received;

[0096] Specifically, it is determined whether a matching success signal is received within a specific time (such as time t1);

[0097] If a matching success signal is received, step S400 is executed to modify the driving parameters of the controller according to the matching success signal.

[0098] That is, for example, the received successful matching signal is that the motor b, compressor a and controller m in the refrigeration system C are adapted and the driving parameters of the controller m for the electronic component group are z1, the driving parameters for the motor b are x2, and the driving parameters for the compressor a are y1. Then, the driving parameters of the controller are modified according to the matching signal, and the driving parameters for the electronic component group are changed to z1, the driving parameters for the motor are changed to x2, and the driving parameters for the compressor are changed to y1.

[0099] If no matching success signal is received, step S500 is executed, matching fails, and a fault message is issued.

[0100] That is, the refrigeration system information matching the electronic component group with driving parameter z1, the motor b with driving parameter x2, the compressor a with driving parameter y1 and the controller m is not found, indicating that the electronic component group, the motor b, the compressor a and the controller m may be incompatible in numbering and model or in other ways, and a fault message is issued.

[0101] The network server queries the refrigeration system information that matches the system information, motor information, compressor information, and controller information. Figure 4 , specifically including the following steps:

[0102] Step S301: The network server reads the system feature tag, the motor feature tag, the compressor feature tag, and the controller feature tag to obtain system information, motor information, compressor information, and controller information.

[0103] For example, it is learned that the system number in the current refrigeration system is system A, the driving parameter of the electronic component group is z1, the model number of the motor is motor b, and its corresponding driving parameter is x2; the model number of the compressor is compressor a, and its corresponding driving parameter is y1; the model number of the controller is m.

[0104] Check whether there is refrigeration system information that matches the system information, motor information, compressor information, and controller information:

[0105] If so, step S302 is executed to obtain the driving parameters of the controller for the electronic component group, the motor and the compressor in the matched system information, and send a matching success signal to the Internet of Things module.

[0106] For example, the network server queries its database and finds that the motor b, compressor a and controller m in system C are adapted and the driving parameters of the controller m for motor b are x2, the driving parameters for compressor a are y1, and the driving parameters for the electronic component group are z1, that is, there is refrigeration system information that matches the system information, motor information, compressor information and controller information in the current refrigeration system, and then sends a matching success signal to the Internet of Things module.

[0107] If not, step S303 is executed to feedback the unmatched items.

[0108] For example, the network server has not found refrigeration system information that matches the system information, motor information, compressor information and controller information in the current refrigeration system in its database. If it is found that motor a, compressor a and controller m in system A are compatible, the network server will send a message that the motor information does not match to the Internet of Things module, and set it as error item 1. If it is found that motor b, compressor b and controller m in system B are compatible, the network server will send a message that the compressor information does not match to the Internet of Things module, and set it as error item 2.

[0109] It should be noted that the network server can query online or offline whether there is refrigeration system information that matches the system information, motor information, compressor information, and controller information.

[0110] Furthermore, after the feedback does not match the project, it also includes:

[0111] Step S304: display rectification suggestions.

[0112] For example, the rectification suggestions given are: the rectification suggestion for error item 1 is to replace the motor with a motor with a model number of motor b; the rectification suggestion for error item 2 is to replace the compressor with a compressor with a model number of compressor b.

[0113] In summary, a refrigeration system and a self-matching method provided by the present invention have the following advantages: a system feature tag storing system information is provided on the refrigeration system, and each component in the refrigeration system is also provided with a component feature tag storing corresponding component information, and an Internet of Things module is also provided on the controller for reading the system feature tag and the feature tag corresponding to each component to obtain system information and each component information, and modify the driving parameters of the controller for the electronic component group, motor and compressor according to the system information and each component information. It can be seen that the present invention, by providing an Internet of Things module on the controller, enables a controller to adapt to a variety of electronic component groups, motors and compressor combinations, thereby improving the universal standardization of the controller, reducing the types of controllers, and reducing the management costs and stocking costs in its procurement, logistics, production, and maintenance.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
