Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of building automation, and in particular, to a method, device, gateway and system for configuring a gateway. BACKGROUND

[0002] In the related art, the access device information of a gateway is often configured based on human experience. This may likely result in too few or too many devices (such as expansion modules, or terminal devices accessing the gateway through the expansion modules, or terminal devices directly accessing the gateway, etc.) accessing the gateway, thereby causing a series of problems. For example, when there are too few expansion modules accessing the gateway, the large-scale device access demand cannot be met. When there are too many expansion modules accessing the gateway, a large amount of data will cause the communication bus to be busy, thereby causing the data of some expansion modules to be unable to be sent in time, affecting the real-time performance of the data, and generating communication failure information.

[0003] In addition, in a building automation system, a lightweight gateway is limited by hardware resources, and has a small running memory space, resulting in that the gateway does not support access to expansion modules, or the number of accessible expansion modules and devices accessing through the expansion modules is small.

[0036] Various exemplary embodiments of the present disclosure will now be described in detail below with reference to the accompanying drawings. Note that the relative arrangement, numerical expressions, and numerical values of components and steps set forth in these embodiments are not limiting to the scope of the present disclosure unless specifically stated otherwise.

[0037] Meanwhile, it should be understood that the sizes of the various portions shown in the drawings are not drawn to scale for the sake of convenience in description.

[0038] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way limiting to the scope of the disclosure and its applications or uses.

[0039] Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail herein, but should be considered as part of the description of the present disclosure.

[0040] In all examples shown and discussed herein, any specific values should be interpreted as merely illustrative and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0041] Note that like reference numerals and letters indicate similar items in the following drawings, and thus once an item is defined in one drawing, it need not be discussed further in subsequent drawings.

[0042] In order to make the purposes, technical solutions, and advantages of the present disclosure clearer, the present disclosure is further described in detail below with reference to specific embodiments and in conjunction with the accompanying drawings.

[0043] In the related art, due to the deficiency of the gateway access device configuration process, the number of devices accessing the gateway is too small or too large, thereby causing a series of problems. In addition, due to the limitation of hardware resources of the gateway itself, the number of devices that can access the gateway is limited, and the large-scale device access demand cannot be met.

[0044] In view of this, the present disclosure proposes a method, device, gateway, and system for configuring a gateway, which can improve the maximum number of devices that can access the gateway, effectively alleviate the problem of too many access devices, and improve the intelligent level of the gateway configuration process.

[0045] Figure 1is a flowchart of a method for configuring a gateway according to some embodiments of the present disclosure. As shown in Figure 1 In some embodiments of the present disclosure, the method for configuring a gateway comprises steps S1 to S5.

[0046] Step S1: Obtain configuration information of an access device of the gateway.

[0047] The access device of the gateway can refer to at least one of an extension module of the gateway, a device accessing the gateway through the extension module, and a device directly accessing the gateway. The device accessing the gateway through the extension module or directly accessing the gateway can be a terminal device, such as an air conditioner indoor unit, an air conditioner outdoor unit, etc.

[0048] The configuration information of the access device can comprise at least one of the type of the access device, data attribute configuration information of the access device, etc.

[0049] For example, the configuration information of the access device comprises the type of the access device and the configuration information of the data attribute. By including both aspects in the configuration information of the access device, the subsequent fine optimization of the basic storage structure of the gateway is facilitated.

[0050] In some examples, the access device of the gateway refers to an extension module of the gateway. In these examples, the following configuration information can be obtained: data attribute configuration information of the extension module.

[0051] In other examples, the access device of the gateway refers to a device accessing the gateway through the extension module. In these examples, the following configuration information can be obtained: the type of the device accessing the gateway through the extension module, and the data attribute configuration information of the device accessing the gateway through the extension module. By obtaining the configuration information of the device accessing through the extension module, the fine level of the gateway configuration process is improved.

[0052] In still other examples, the access device of the gateway refers to the extension module and the device accessing the gateway through the extension module. In these examples, the following configuration information can be obtained: the type of the extension module, the data attribute configuration information of the extension module, the type of the device accessing the gateway through the extension module, and the data attribute configuration information of the device accessing the gateway through the extension module. By obtaining the configuration information of the extension module and the device accessing through the extension module, both the configuration granularity of the extension module and the device accessing through the extension module are taken into account, which helps to further improve the fine level of the gateway configuration process.

[0053] In step S1, there can be multiple ways to obtain the configuration information. In one example, the configuration information of the access device of the gateway is received from a configuration management device. In another example, the configuration information of the access device of the gateway is obtained from a local storage module.

[0054] Step S2: optimizing the basic data storage structure in the gateway according to the configuration information of the access device to obtain an optimized data storage structure.

[0055] The basic data storage structure in the gateway can be one or more. The basic data storage structure defines a plurality of attributes and the storage space occupied by each attribute. For example, the basic data storage structure is shown in Table 1.

[0056] Table 1

[0057]

[0058] As shown in Table 1, the basic data storage structure includes the following attributes of the data: name, address, data type, value, value range, operation formula, extension flag, unit, and priority. For each attribute in the basic data storage structure, a storage space is pre-allocated. For example, the storage space of the attribute "name" is N4 bytes, and the storage space of the attribute "data type" is N1 bytes.

[0059] It should be noted that Table 1 is only an example of the basic data storage structure. In actual implementation, the attributes included in the basic data storage structure and the storage space of each attribute can be flexibly set according to requirements.

[0060] In step S2, by optimizing the basic data storage structure, the storage space occupied by the optimized data storage structure is less than the storage space occupied by the basic data storage structure. In this way, adaptive compression can be performed on the data storage space occupied by each access device in the gateway, which helps the gateway to access more access devices.

[0061] In step S2, a variety of implementation methods can be used to optimize the storage structure. The following describes two exemplary methods.

[0062] In the first exemplary method, the configuration information of the access device includes the configuration information of the data attributes of the access device. In this method, the basic data storage structure is optimized according to the configuration information of the data attributes of the access device to obtain an optimized data storage structure.

[0063] For example, the gateway has a basic data storage structure. Assuming that the data attribute configuration information of terminal device a accessing the gateway is obtained, the basic data storage structure is optimized according to the data attribute configuration information of terminal device a to obtain an optimized data storage structure.

[0064] For example, the gateway has a basic data storage structure. Assuming that the configuration information of the data attribute of terminal device a accessing the gateway and the configuration information of the data attribute of terminal device b accessing the gateway are obtained, the basic data storage structure can be optimized according to the configuration information of the data attribute of terminal device a to obtain an optimized data storage structure p1, and the basic data storage structure can be optimized according to the configuration information of the data attribute of terminal device b to obtain an optimized data storage structure p2.

[0065] In the second exemplary manner, the configuration information of the access device includes the type of the access device and the configuration information of the data attribute of the access device. In this exemplary manner, the storage structure optimization step (i.e., step S2) specifically includes Figure 2 The steps S21 to S22 shown.

[0066] Step S21: Select a basic data storage structure corresponding to the type of the access device as a target storage structure.

[0067] In the second exemplary manner, the gateway has a plurality of basic data storage structures, and a corresponding relationship exists between the basic data storage structures and the device types. For example, the device type 1 corresponds to the basic data storage structure p1, and the device type 2 corresponds to the basic data storage structure p2. After the type of the access device is determined, the target storage structure is selected from the plurality of basic data storage structures according to the type of the access device.

[0068] For example, when the access device is terminal device a and terminal device b accessing through the expansion module A, and the device type of terminal device a is type 1 and the device type of terminal device b is type 2, the basic data storage structure corresponding to type 1 can be selected as the target storage structure of terminal device a, and the basic data storage structure corresponding to type 2 can be selected as the target storage structure of terminal device b.

[0069] For example, when the access device is terminal device a accessing through the expansion module A, and the device type of terminal device a is type 1, the basic data storage structure corresponding to type 1 can be selected as the target storage structure.

[0070] In the embodiments of the present disclosure, by setting the corresponding basic data storage structure for different types of devices, the flexibility of subsequent data storage structure optimization is improved. Moreover, compared with setting only one basic data storage structure for the gateway, since the basic storage structure designed for a specified type of device does not need to take into account the data attributes of various types of devices, the storage space occupied by the basic data storage structure is reduced, which helps the gateway to access more devices.

[0071] Step S22: Optimize the target storage structure according to the data attribute configuration information of the access device.

[0072] In some examples, in the case that the data attribute configuration information of one access device is acquired, the target storage structure of the access device is optimized to obtain the optimized data storage structure of the access device.

[0073] For example, assuming that the basic data storage structure shown in Table 1 is optimized to obtain the optimized data storage structure shown in Table 2.

[0074] Table 2

[0075]

[0076] As shown in Table 2, the optimized data storage structure includes five attributes, i.e., name, address, data type, value, and priority, and the storage spaces occupied by the attributes are N2 bytes, N1 bytes, N1 bytes, N1 bytes, and N1 bytes, respectively. Among them, N4>N2>N1. In this example, the number of attributes of the optimized data storage structure is less than that of the basic data storage structure, and the storage spaces occupied by the attributes are also less than those of the basic data storage structure. Therefore, the storage space occupied by the optimized data storage structure is less than that of the basic data storage structure.

[0077] In other examples, in the case that the data attribute configuration information of multiple access devices is acquired, the target storage structure of each access device is optimized according to the data attribute configuration information of the access device to obtain the optimized data storage structure of the access device.

[0078] In the embodiments of the present disclosure, by the flow shown in Figure 2 , the flexibility and accuracy of the storage structure optimization can be improved, and the process of configuring the access devices for the gateway is further optimized.

[0079] Returning to Figure 1 , step S3: determining the storage space occupied by the access device in the gateway according to the storage space occupied by the optimized data storage structure.

[0080] In some examples, in the case that the access devices are multiple, the storage spaces occupied by the optimized data storage structures corresponding to the access devices are summed up; and the storage space occupied by the access devices is determined according to the sum result.

[0081] Further, in some of the above examples, the storage spaces can be summed up according to the following formula: F1=m1*n1+m2*n2+…+mx*nx, wherein F1 is the summation result of the storage space, m1 is the storage space occupied by the optimized data storage structure corresponding to the access device 1, n1 is the data amount of the access device 1 using the optimized data storage structure, m2 is the storage space occupied by the optimized data storage structure corresponding to the access device 2, n2 is the data amount of the access device 2 using the optimized data storage structure, mx is the storage space occupied by the optimized data storage structure corresponding to the access device x, and nx is the data amount of the access device x using the optimized data storage structure.

[0082] In addition, in some examples described above, the summation of the storage space can also be performed according to the following formula: F1=c1*d1+c2*d2+…+cx*dx, wherein F1 is the summation result of the storage space, c1 is the storage space occupied by the optimized data storage structure corresponding to type 1, d1 is the data amount of all the access devices using the optimized data storage structure, c2 is the storage space occupied by the optimized data storage structure corresponding to type 2, d2 is the data amount of all the access devices using the optimized data storage structure, cx is the storage space occupied by the optimized data storage structure corresponding to type x, and dx is the data amount of all the access devices using the optimized data storage structure.

[0083] After obtaining the summation result, the summation result can be taken as the storage space occupied by the access devices. In addition, the summation result can be further operated to obtain the storage space occupied by the access devices.

[0084] In some other examples, in the case where the access device is one, the storage space occupied by the optimized data storage structure corresponding to the access device is taken as the storage space occupied by the access device. In addition, the storage space occupied by the optimized data storage structure corresponding to the access device can be further operated to obtain the storage space occupied by the access device.

[0085] Step S4: determining the residual access capability representation index of the gateway according to the running memory space of the gateway and the storage space occupied by the access devices in the gateway.

[0086] The residual access capability representation index of the gateway is used to represent the residual device access capability of the gateway.

[0087] In some examples, the remaining access capability representation index of the gateway comprises a remaining storage space of a running memory of the gateway. In these examples, step S4 specifically comprises: calculating a difference between the running memory space of the gateway and a storage space occupied by the access device in the gateway; and determining the remaining storage space of the running memory of the gateway according to the difference. For example, the difference is taken as the remaining storage space of the running memory. By calculating the remaining storage space of the running memory of the gateway, the user can be informed of the current remaining access capability of the gateway, and the number of access devices configured for the gateway can be reasonably determined according to the current remaining access capability, thereby improving the controllability and intelligent level of the gateway configuration process.

[0088] In other examples, the remaining access capability representation index of the gateway comprises a remaining storage space of a running memory of the gateway and a configurable data amount of at least one remaining access device. In these examples, step S4 specifically comprises: calculating a difference between the running memory space of the gateway and a storage space occupied by the access device in the gateway; determining the remaining storage space of the running memory of the gateway according to the difference; and determining the configurable data amount of each remaining access device according to the remaining storage space of the running memory of the gateway and a storage space occupied by a corresponding basic data storage structure of each remaining access device.

[0089] In these examples, the remaining access device refers to a device that can still be accessed by the gateway. For example, the remaining access device comprises a device of type "type 1" and a device of type "type 2". In this example, after obtaining the remaining storage space of the running memory of the gateway, the quotient of the remaining storage space of the running memory of the gateway and a storage space occupied by the basic data storage structure corresponding to the device of "type 1" is calculated, and the configurable data amount of the device of "type 1" is obtained according to the quotient; the quotient of the remaining storage space of the running memory of the gateway and a storage space occupied by the basic data storage structure corresponding to the device of "type 2" is calculated, and the configurable data amount of the device of "type 2" is obtained according to the quotient.

[0090] In the above examples, by calculating the remaining storage space of the running memory and the configurable data amount of the remaining access device, the remaining access capability of the gateway can be better represented, and the intelligent level of the gateway configuration process is further improved.

[0091] Further, in addition to steps S1 to S4, the method for configuring the gateway can further comprise: outputting configuration prompt information carrying the remaining access capability representation index of the gateway. By outputting the configuration prompt information, the user can reasonably determine the number of access devices according to the configuration prompt information, thereby improving the configuration experience of the user.

[0092] In the embodiments of the present disclosure, on one hand, by optimizing the basic data storage structure in the gateway according to the configuration information of the gateway access device, the adaptive compression of the storage space occupied by the data of the access device in the gateway is facilitated, and the maximum device quantity that can be accessed by the gateway is improved; on the other hand, by calculating the residual access capability representation index of the gateway, the user can configure a reasonable number of access devices for the gateway according to the index, effectively alleviate the problems caused by too few or too many access devices, and improve the intelligent level of the gateway configuration.

[0093] In order to better illustrate the optimization process of the storage structure, the following will be exemplarily described in combination with Figure 3 the steps S22 shown in FIG. 2. Figure 2 As shown in FIG. 2, the step S22 specifically includes steps S221 to S223. Figure 3

[0094] Step S221: According to the data attribute configuration information, the optimization level of each attribute in the target storage structure is determined.

[0095] The data attribute configuration information includes the value of the first attribute. The first attribute can be one or more attributes in the target storage structure.

[0096] In some examples, the first attribute is all the attributes in the target storage structure. In these examples, the step S221 includes: according to the value of the first attribute, the optimization level of each attribute in the target storage structure is determined.

[0097] Further, in the above examples, the actual storage space occupied by the first attribute can be estimated according to the value of the first attribute, and then the optimization level of the first attribute is determined according to the actual storage space occupied.

[0098] For example, assuming that the value of the first attribute “name” is configured as “temperature”, the actual storage space occupied by this attribute can be estimated to be greater than N1 bytes and less than N2 bytes, and then the optimization level of this attribute is determined to be M2 according to the actual storage space occupied.

[0099] In the above examples, the above process can meet the application scene use demand of the user for full-quantity configuration of the data attribute, and the optimization level of each attribute in the target storage structure can be accurately determined, and then the storage space occupied by each attribute can be accurately compressed subsequently.

[0100] ​In some examples, the first attribute is a part attribute in the target storage structure. In these examples, step S221 comprises: determining the optimization level of the first attribute according to the value of the first attribute; in the case that the target storage structure further comprises a second attribute associated with the first attribute, determining the value of the second attribute according to the value of the first attribute and the logical relationship between the attributes; and determining the optimization level of the second attribute according to the value of the second attribute.

[0101] Further, in the above-mentioned some examples, step S221 can further comprise: in the case that the target storage structure further comprises a third attribute other than the first attribute and the second attribute, setting the optimization level of the third attribute as a setting value, the setting value corresponding to the same optimization storage space as the storage space of the third attribute in the target storage structure.

[0102] For example, assuming that the target storage structure is as shown in Table 1, and the first attribute involved in the configuration information of the access device is the five attributes of “name”, “address”, “data range”, “extension flag”, and “priority”, and the target storage structure further comprises the four attributes of “data type”, “value”, “operation formula”, and “unit”. Among them, “unit” is an associated attribute of “extension flag”, and thus it belongs to the second attribute, and “data type”, “value”, and “operation formula” belong to the third attribute. Further, assuming that the value of “extension flag” is 0, and it is known through the query of the logical relationship between the attributes that when the value of “extension flag” is 0, the value of the associated attribute “unit” is also 0, and thus the optimization level of the second attribute “unit” is determined as M0. And the optimization level of the three third attributes of “data type”, “value”, and “operation formula” can be set as a setting value, the setting value corresponding to the same optimization storage space as their storage space in the target storage structure.

[0103] In the above-mentioned examples, the above process can meet the application scenario use requirements of the user for partial configuration of data attributes, and can accurately determine the optimization level of each attribute for the first attribute, the second attribute, and the third attribute, and thus facilitate subsequent accurate compression of the storage space occupied by each attribute.

[0104] Step S222: determining the optimization storage space of each attribute according to the optimization level of each attribute and the corresponding relationship between the optimization level and the storage space of the attribute.

[0105] The corresponding relationship between the optimization level and the storage space of the attribute defines the optimization storage space of the attribute corresponding to each optimization level. Table 3 gives an example of the corresponding relationship.

[0106] Table 3

[0107]

[0108] As shown in Table 3, the storage space of the attribute corresponding to the optimization level M0 is 0 bytes, the storage space of the attribute corresponding to the optimization level M1 is N1 bytes, the storage space of the attribute corresponding to the optimization level M2 is N2 bytes, the storage space of the attribute corresponding to the optimization level M3 is N3 bytes, and the storage space of the attribute corresponding to the optimization level M4 is N4 bytes. N1 to N4 are all integers greater than 0.

[0109] Step S223: determining the optimized data storage structure according to the optimized storage space of each attribute.

[0110] In some examples, step S223 includes: deleting, from each attribute, an attribute whose optimized storage space is zero to obtain remaining attributes; and obtaining the optimized data storage structure according to the remaining attributes.

[0111] For example, assuming that the target data storage structure contains 9 attributes, and it is determined through calculation that the optimized storage space of two attributes among the 9 attributes is zero, the two attributes are deleted, and the optimized data storage structure is constructed according to the remaining 7 attributes.

[0112] In Figure 3 In the flow shown in FIG. 4, the attribute of the data is taken as the optimization granularity of the storage structure, which improves the fine level of the storage structure optimization and further optimizes the gateway configuration process. Moreover, by pre-setting the correspondence between the optimization level and the storage space of the attribute and determining the optimized storage space of each attribute according to the correspondence in the storage structure optimization process, the processing efficiency of the storage structure optimization can be improved.

[0113] Figure 4 is a flow diagram of a method for configuring a gateway according to another embodiment of the present disclosure. As shown in Figure 4 In another embodiment of the present disclosure, the method for configuring a gateway includes steps 41 to 47.

[0114] Step 41: a user configures access device information of the gateway.

[0115] The user can configure the access device information of the gateway through an interactive interface provided by the configuration management device. For example, the user can configure information of an extension module accessed by the gateway and a terminal device accessed by the extension module.

[0116] Step 42: the configuration management device sends the configuration information of the access device of the gateway to the gateway.

[0117] The configuration management device can be a host computer installed with configuration software. After receiving the configuration information input by the user, the configuration management device sends the configuration information to the gateway.

[0118] Step 43: the gateway optimizes the basic data storage structure.

[0119] In this step, the gateway optimizes the basic data storage structure in the gateway according to the configuration information of the access device, to obtain an optimized data storage structure.
