[0043] The following sections provide detailed descriptions of the energy efficiency terminal host, energy efficiency terminal slave, and energy efficiency terminal provided in this application.

[0044] First, this application provides an energy efficiency terminal host, please refer to... Figure 1 , Figure 1 This is a schematic diagram of a structure of an energy efficiency terminal host provided in an embodiment of this application. The energy efficiency terminal host 10 may include a first main control module 110, a first storage module 120, a first uplink communication module 130, and a first downlink communication module 140. The first uplink communication module 130 can be connected to both the upper-layer control module 20 and the first main control module 110 to transmit network information from the upper-layer control module 20 to the first main control module 110. This network information can be used to characterize the relationship between the energy efficiency terminal host 10 and multiple energy efficiency terminal slaves (such as the first energy efficiency terminal slave 31, the second energy efficiency terminal slave 31, the third energy efficiency terminal slave 32, the fourth energy efficiency terminal slave 32, the fifth energy efficiency terminal slave 32, the sixth energy efficiency terminal slave 32, the seventh energy efficiency terminal slave 32, the eleventh ... The network type of the energy efficiency terminal slave (32, ..., Nth energy efficiency terminal slave 3n, where N is an integer greater than 1) can include networking by searching for the wireless serial number of the energy efficiency terminal slave, networking according to the set number of wireless serial numbers of the energy efficiency terminal slave, or networking according to the file information of the received energy efficiency terminal slave; the first main control module 110 is connected to the first storage module 120 and the first downlink communication module 140 respectively, so as to transmit the networking information to the first storage module 120 for storage and control the first downlink communication module 140 to network and communicate with multiple energy efficiency terminal slaves according to the networking information.

[0045] In this embodiment, the upper-layer control module 20 may be an upper-layer gateway or an upper-layer system, etc. The user can send the networking information to the energy efficiency terminal host 10 through the upper-layer control module 20.

[0046] The first uplink communication module 130 is connected to both the upper-layer control module 20 and the first main control module 110, meaning it connects the upper-layer control module 20 and the first main control module 110. It is used to transmit network information from the upper-layer control module 20 to the first main control module 110. Understandably, the first uplink communication module 130 can also transmit feedback information from the first main control module 110 to the upper-layer control module 20, allowing the upper-layer control module 20 to determine the current network configuration based on this feedback information.

[0047] The first main control module 110 can be any existing controller, such as a microcontroller unit (MCU), a system-on-chip (SOC), or a microcontroller. The specific type can be determined according to the actual application scenario, and no limitation is made here.

[0048] The first master control module 110 can control the first downlink communication module 140 to network and communicate with multiple energy efficiency terminal slaves based on the received network information. Furthermore, the first master control module 110 can also transmit the network information to the first storage module 120 for storage. The first storage module 120 can be any existing memory or storage chip, such as random access memory (RAM). Understandably, the first storage module 120 can also be used to store various information such as the file information of the energy efficiency terminal slaves and the connection information between the master and energy efficiency terminal slaves; the specific use case can be determined according to the actual application scenario and is not limited here.

[0049] The first downlink communication module 140 is connected to the first master control module 110 and the energy efficiency terminal slave respectively. That is, the first downlink communication module 140 is connected between the first master control module 110 and the energy efficiency terminal slave, and is used to communicate with each energy efficiency terminal slave according to the instructions of the first master control module 110 to form a network and exchange data.

[0050] In this embodiment, the energy efficiency terminal host 10 can form a network by searching for the wireless serial numbers of the energy efficiency terminal slaves, forming a network according to the set number of wireless serial numbers of the energy efficiency terminal slaves, or forming a network according to the received file information of the energy efficiency terminal slaves. It is understood that the first downlink communication module 140 can use any existing communication method to communicate with each energy efficiency terminal slave, such as wired communication or wireless communication. Wired communication includes but is not limited to bus communication, and wireless communication includes but is not limited to Bluetooth communication, Wi-Fi communication, ZigBee communication, etc. The specific method can be determined according to the actual application scenario, and is not limited here.

[0051] Similarly, the first uplink communication module 130 can also obtain network information through wired or wireless means. Therefore, the first uplink communication module 130 can also use any existing wired or wireless communication method to communicate with the upper-layer control module 20. Among them, wired communication includes but is not limited to bus communication, and wireless communication includes but is not limited to Bluetooth communication, Wi-Fi communication, ZigBee communication, etc. The specific method can be determined according to the actual application scenario, and is not limited here.

[0052] In this embodiment, the first uplink communication module 130 is connected to the upper-layer control module 20 to receive networking information and transmit it to the first main control module 110. The first main control module 110, based on the networking type represented by the networking information, uses the first downlink communication module 140 to network and communicate with multiple energy efficiency terminal slaves. The networking types include networking by searching for the wireless serial numbers of the energy efficiency terminal slaves, networking based on the set number of wireless serial numbers of the energy efficiency terminal slaves, or networking based on the received file information of the energy efficiency terminal slaves. This allows the energy efficiency terminal host 10 to interact with the energy efficiency terminal slaves even when there is no communication address for the energy efficiency terminal slaves. Compared with related technologies where the host needs to receive the slave address to interact with the slaves, this reduces the time for on-site configuration and debugging, improves networking efficiency, and broadens the application scenarios of energy efficiency terminals.

[0053] Next, continue with Figure 1 The unit modules shown are described in detail, as well as the specific implementation methods that may be used in practical applications.

The first uplink bus interface 13021 is connected to the first communication bus S1. The bus communication module of the upper-level control module 20 is also connected to the first communication bus S1. Then, the upper-level control module 20 can send networking information to the first uplink bus interface 13021 through the first communication bus S1, and then the first uplink bus interface 13021 transmits it to the first main control module 110. Alternatively, the first main control module 110 can transmit feedback information to the first communication bus S1 through the first uplink bus interface 13021, so that the upper-level control module 20 can obtain the feedback information from the first communication bus S1. The transmission of networking information, feedback information, etc. can also be realized.

[0057] like Figure 4 As shown, as another example, the first uplink communication module 130 includes a first uplink wireless module 1301 and a first uplink bus module 1302. The first main control module 110 can obtain network information from the first uplink wireless module 1301 wirelessly, or from the first uplink bus interface 13021 via bus communication. Similarly, the first main control module 110 can also send feedback information to the upper-layer control module 20 via wireless or bus communication to achieve data interaction. The specific method can be determined according to the actual application scenario, and is not limited here.

[0058] Similarly, in some embodiments of this application, the first downlink communication module 140 may include a first downlink wireless module 1401 and / or a first downlink bus module 1402; wherein, the first downlink wireless module 1401 communicates wirelessly with multiple energy efficiency terminal slaves; the first downlink bus module 1402 may include a first downlink bus interface 14021, which and the multiple energy efficiency terminal slaves are respectively connected to a second communication bus S2 to perform bus communication through the second communication bus S2.

The first downlink wireless module 1401 is connected to the wireless communication module of each energy efficiency terminal slave, thereby enabling data interaction, such as obtaining device information of each energy efficiency terminal slave, collected data, or sending control commands to each energy efficiency terminal slave.

[0060] like Figure 6 As shown, as another example, the first downlink communication module 140 includes a first downlink bus module 1402, which can be any existing bus communication module, such as an RS485 module. The first downlink bus module 1402 is configured with a first downlink bus interface 14021, such as an RS485 interface. The first downlink bus interface 14021 is connected to the second communication bus S2, and the bus communication modules of each energy efficiency terminal slave are also connected to the second communication bus S2 to realize data interaction.

[0061] like Figure 7 As shown, as another example, the first downlink communication module 140 includes a first downlink wireless module 1401 and a first downlink bus module 1402. The first master control module 110 can obtain networking information by interacting with each energy efficiency terminal slave through the first downlink wireless module 1401 wirelessly, or by interacting with each energy efficiency terminal slave through the first downlink bus interface 14021 via bus communication. The specific method can be determined according to the actual application scenario, and is not limited here.

[0063] In this embodiment, the power supply module 150 can be any existing switching power supply or a combination of multiple switching power supplies. The power supply module 150 can generate corresponding voltage signals according to the working voltage required for the operation of the first main control module 110, the first storage module 120, the first uplink communication module 130 and the first downlink communication module 140, and output them to the first main control module 110, the first storage module 120, the first uplink communication module 130 and the first downlink communication module 140 respectively, so as to supply power to the aforementioned modules and enable them to work stably.

[0064] like Figure 9 As shown, as an example, the power module 150 includes a DC-DC isolated switching power supply 1501 and an AC-DC isolated switching power supply 1502. The DC-DC isolated switching power supply 1501 and the AC-DC isolated switching power supply 1502 generate power supply voltage signals to supply power to the first main control module 110, the first storage module 120, the first uplink communication module 130 and the first downlink communication module 140.

[0065] In this embodiment, the DC-DC isolated switching power supply 1501 can be any existing DC-DC isolated switching power supply. The DC-DC isolated switching power supply 1501 can be connected to the power supply terminal VCC through the first diode D1, and the power supply terminal VCC outputs a power supply voltage signal to provide stable power to each module.

[0066] The AC-DC isolated switching power supply 1502 can be any existing AC-DC isolated switching power supply. The AC-DC isolated switching power supply 1502 can be connected to the power supply terminal VCC through the second diode D2, and the power supply voltage signal is output from the power supply terminal VCC to provide stable power to each module.

[0067] Understandably, if the operating voltages of the aforementioned modules are different, a step-up / step-down module (not shown in the figure) can also be connected to the power supply terminal VCC. The step-up / step-down module converts the power supply voltage signal into the corresponding operating voltage signal and outputs it to each module, so that each module can work stably.

[0068] Based on the above embodiments, this application also provides an energy efficiency terminal slave device, such as... Figure 10 As shown, the energy efficiency terminal slave unit 30 may include a second master control module 310, a slave function module 320, and a second uplink communication module 330. The second uplink communication module 330 may be connected to the energy efficiency terminal host 10 and the second master control module 310 respectively to transmit command signals from the energy efficiency terminal host 10 to the second master control module 310.

The slave function module 320 is connected to the second master control module 310 to exchange data or signals. Thus, the function type of the energy efficiency terminal slave 30 can be implemented by the slave function module 320. The specific type can be determined according to the actual application scenario, and is not limited here.

[0070] The second main control module 310 can be any existing controller, such as a microcontroller unit (MCU), system-on-chip (SOC), or microcontroller. The specific type can be determined according to the actual application scenario, and is not limited here.

[0071] The second uplink communication module 330 is connected to the second main control module 310 and the energy efficiency terminal host 10 respectively. That is, the second uplink communication module 330 is connected between the second main control module 310 and the energy efficiency terminal host 10. It can transmit instruction information from the energy efficiency terminal host 10, such as reading device information frames, to the second main control module 310, or transmit feedback information from the second main control module 310, such as reply frames, to the energy efficiency terminal host 10, thereby realizing the interaction between the energy efficiency terminal host 10 and the energy efficiency terminal slave 30.

[0073] In this embodiment, the energy efficiency terminal host 10 establishes a network and communicates with the energy efficiency terminal slave 30 through the second uplink communication module 330 according to the network type represented by the network information. The network type includes networking by searching for the wireless serial number of the energy efficiency terminal slave, networking according to the set number of wireless serial numbers of the energy efficiency terminal slave, or networking according to the received file information of the energy efficiency terminal slave. This allows the energy efficiency terminal host 10 to interact with the energy efficiency terminal slave 30 even when there is no communication address of the energy efficiency terminal slave 30. Compared with related technologies where the host needs to receive the slave address to interact with the slave, this reduces the on-site configuration and debugging time, improves networking efficiency, and broadens the application scenarios of the energy efficiency terminal.

[0075] In some embodiments of this application, the second uplink communication module 330 may include a second uplink wireless module 3301 and / or a second uplink bus module 3302; the second uplink wireless module 3301 may wirelessly communicate with the energy efficiency terminal host 10; the second uplink bus module 3302 may include a second uplink bus interface 33021, and the second uplink bus interface 33021 and the energy efficiency terminal host 10 may be respectively connected to the second communication bus S2 to perform bus communication through the second communication bus S2.

[0076] like Figure 11 As shown, as an example, the second uplink communication module 330 includes a second uplink wireless module 3301, which can be any existing wireless communication module, such as a Bluetooth module. The second uplink wireless module 3301 is connected to the wireless communication module of the energy efficiency terminal host 10, so that data can be exchanged.

[0077] like Figure 12 As shown, as another example, the second uplink communication module 330 includes a second uplink bus module 3302. This second uplink bus module 3302 can be any existing bus communication module, such as an RS485 module. The second uplink bus module 3302 is configured with a second uplink bus interface 33021, such as an RS485 interface. This second uplink bus interface 33021 is connected to the second communication bus S2. The bus communication module of the energy efficiency terminal host 10 is also connected to this second communication bus S2. Therefore, the energy efficiency terminal host 10 and... The second main control module 310 can achieve data interaction through the second communication bus S2. For example, the energy efficiency terminal host 10 can send a read device information frame to the second communication bus S2, and then the second uplink bus interface 33021 can obtain the read device information frame from the second communication bus S2 and transmit it to the second main control module 310. Alternatively, the second main control module 310 can transmit a reply frame to the second communication bus S2 through the second uplink bus interface 33021, so that the energy efficiency terminal host 10 can obtain the reply frame from the second communication bus S2.

[0078] like Figure 13 As shown, as another example, the second uplink communication module 330 includes a second uplink wireless module 3301 and a second uplink bus module 3302. The second main control module 310 can communicate with the energy efficiency terminal host 10 wirelessly via the second uplink wireless module 3301, or via bus communication via the second uplink bus interface 33021. Similarly, the second main control module 310 can also send a reply frame to the energy efficiency terminal host 10 via wireless or bus communication to achieve data interaction. The specific method can be determined according to the actual application scenario, and is not limited here.

[0079] like Figure 14 As shown, in some embodiments of this application, the energy efficiency terminal slave 30 may further include a power conversion module 340, which may be connected to the second master control module 310, the slave function module 320 and the second uplink communication module 330 respectively, to supply power to the second master control module 310, the slave function module 320 and the second uplink communication module 330.

[0080] In this embodiment, the power conversion module 340 can also use any existing switching power supply or a combination of multiple switching power supplies. The power conversion module 340 can generate corresponding voltage signals according to the working voltage required for the operation of the second master control module 310, the slave function module 320 and the second uplink communication module 330, and output them to the second master control module 310, the slave function module 320 and the second uplink communication module 330 respectively, so as to supply power to the aforementioned modules and enable them to work stably.

[0081] Alternatively, the power conversion module 340 can also receive the power voltage signal generated by the power module 150, convert the power voltage signal into a corresponding voltage signal and output it to the second master control module 310, the slave function module 320 and the second uplink communication module 330 respectively, so as to supply power to the aforementioned modules.

[0082] Based on the above embodiments, this application also provides an energy-efficient terminal, which may include, for example: Figures 1 to 9 Corresponding to the energy efficiency terminal host in any embodiment and such Figures 10 to 14 Corresponding to the energy efficiency terminal slave in any embodiment; the energy efficiency terminal host 10 and multiple energy efficiency terminal slaves are communicatively connected to perform networking and data interaction with the multiple energy efficiency terminal slaves according to the received networking information. The networking information is used to characterize the networking type between the energy efficiency terminal host and the multiple energy efficiency terminal slaves. The networking type includes networking by searching for the wireless serial number of the energy efficiency terminal slave, networking according to the set number of wireless serial numbers of the energy efficiency terminal slave, or networking according to the received file information of the energy efficiency terminal slave.

[0083] like Figure 15 As shown, as an example, the energy efficiency terminal host 10 connects to multiple energy efficiency terminal slaves wirelessly, such as via Bluetooth, to achieve networking and data exchange. In this scenario, the energy efficiency terminal host 10 can form a network by searching for the wireless serial numbers of the energy efficiency terminal slaves, or it can form a network based on a set number of wireless serial numbers of the energy efficiency terminal slaves.

[0084] like Figure 16As shown, as another example, the energy efficiency terminal host 10 is connected to multiple energy efficiency terminal slaves via bus communication methods such as RS485 bus communication to achieve networking and data interaction. In this scenario, the energy efficiency terminal host 10 can form a network based on the file information received from the energy efficiency terminal slaves.

[0085] like Figure 17 As shown, as another example, the energy efficiency terminal host 10 can connect with the first energy efficiency terminal slave 31 and the second energy efficiency terminal slave 32 via bus communication, such as RS485 bus communication, to achieve networking and data interaction; and connect with the Nth energy efficiency terminal slave 3n via wireless communication, such as Bluetooth, to achieve networking and data interaction. In this scenario, the energy efficiency terminal host 10 can form a network by searching for the wireless serial numbers of the energy efficiency terminal slaves, or form a network with the first energy efficiency terminal slave 31 and the second energy efficiency terminal slave 32 according to the set number of wireless serial numbers of the energy efficiency terminal slaves, and form a network with the Nth energy efficiency terminal slave 3n according to the received file information of the energy efficiency terminal slaves.

[0086] Understandable, such as Figure 18 As shown, in some other embodiments, the energy efficiency terminal host 10 can also communicate with each energy efficiency terminal slave device both via an RS485 bus and via Bluetooth. In this scenario, the energy efficiency terminal host 10 can form a network by searching for the wireless serial numbers of the energy efficiency terminal slave devices, forming a network according to a set number of wireless serial numbers of the energy efficiency terminal slave devices, forming a network with the Nth energy efficiency terminal slave device 3n based on the received file information of the energy efficiency terminal slave device, or forming a network according to a set communication priority order combined with the aforementioned networking methods. The communication priority order can be that RS485 communication has a higher priority than Bluetooth communication. In this case, if the slave device file information is received, networking can be performed first based on the file information. If networking fails, networking can then be performed by searching for the wireless serial numbers of the energy efficiency terminal slave devices. Alternatively, the communication priority order can also be that Bluetooth communication has a higher priority than RS485 communication. The specific priority can be determined according to the actual application scenario and is not limited here.

[0087] In this embodiment, when the energy efficiency terminal host 10 and each energy efficiency terminal slave communicate via the RS485 interface, both the standard Modbus RTU protocol and a custom protocol can be supported. Using the standard Modbus RTU protocol, a 12-bit code can be set for each energy efficiency terminal slave to uniquely represent it. The address field of the custom protocol also uses a 12-bit code, while other fields are the same as the standard Modbus RTU protocol. The standard Modbus RTU protocol address is 1 byte, while the custom protocol uses 6 bytes, as shown in Tables 1 to 4, which contain relevant content for the custom protocol. It supports read and write commands under custom command 03 and custom command 16.

[0096]

[0097] In this embodiment, when the energy efficiency terminal host 10 and each energy efficiency terminal slave communicate via Bluetooth, the searchable name of the Bluetooth interface is prefixed with ZT + 12-bit encoding, which is a 6-byte communication address of a custom protocol. For example, if the 6-byte communication address is 0x20, 0x24, 0x10, 0x03, 0x00, 0x01, then the Bluetooth name is ZT202410030001. After Bluetooth communication is established, the interaction between the energy efficiency terminal host and the energy efficiency terminal slave is performed using Bluetooth transparent point-to-point mode. That is, when the energy efficiency terminal host communicates with multiple energy efficiency terminal slaves, after establishing a connection with one of the energy efficiency terminal slaves, the energy efficiency terminal host reads data through transparent point-to-point mode, then disconnects from that energy efficiency terminal slave, and continues to establish a connection with the next energy efficiency terminal slave. After the Bluetooth connection enters transparent transmission, communication can be performed using a custom protocol of the RS485 interface.

[0098] In other words, in this embodiment of the application, when the energy efficiency terminal host 10 and the energy efficiency terminal slave communicate via Bluetooth or RS485, they can both support the standard Modbus RTU protocol and custom protocols.

[0099] Based on the above embodiments, this application also provides a networking method, which can be applied to the energy efficiency terminal host in any of the above embodiments. The networking method may include the following steps.

[0100] Step 1: In response to the networking information from the upper-layer control module, search for multiple energy efficiency terminal slave devices and record the names of the target slave devices that match the preset naming rules. These preset naming rules are prefixed with ZT and followed by a 12-bit encoding. This networking information indicates that the energy efficiency terminal host forms a network by searching for the wireless serial numbers of the energy efficiency terminal slave devices. In this scenario, the upper-layer control module does not need to send the slave device addresses of the energy efficiency terminal slave devices to the energy efficiency terminal host; the energy efficiency terminal host forms a network by searching for the wireless serial numbers of the energy efficiency terminal slave devices, such as Bluetooth serial numbers.

[0101] Step 2: Obtain the target wireless serial number corresponding to the energy efficiency terminal slave based on the target slave name, and obtain the unique code of the energy efficiency terminal slave based on the target wireless serial number, that is, convert the target wireless serial number into a 6-byte address code.

[0102] Step 3: Set the number of identifications n to a preset initial value, such as 0. Establish a wireless connection with the corresponding energy efficiency terminal slave device according to each target wireless serial number and send a frame to read device information.

[0103] Step 4: If a response frame is received from the energy efficiency terminal slave, the file information of the energy efficiency terminal slave is established according to the response frame, and the number of identifications is increased according to the preset step value.

[0104] The information in this file may include the type of energy efficiency terminal slave device, the quality of the communication signal, etc. If the preset step value is set to 1, the number of identifications is n+1, and so on, until all energy efficiency terminal slave devices recorded have been identified.

[0105] Step 5: Based on each file information, poll the data of each energy efficiency terminal slave. If data is received from the energy efficiency terminal slave, control the counter of the energy efficiency terminal slave to be cleared to zero. Otherwise, update the counter value. When the counter value is greater than the preset threshold, delete the file information of the energy efficiency terminal slave and reduce the number of identifications according to the preset step value.

[0106] After identification is complete, the energy efficiency terminal host begins data interaction with each energy efficiency terminal slave, polling the data from each slave. If data is received from a slave, the slave's counter is reset to zero; otherwise, the counter value is incremented by 1. This counter represents the number of times there has been no data interaction between the slave and the host. If no data is received from the slave, the counter value is incremented by 1. If the updated count value is greater than a preset threshold, it means that the slave has failed to interact with the host multiple times. In this case, the slave's profile can be deleted, and the current identification count n is decremented by 1.

[0107] Understandably, if a new target slave name that matches the preset naming rules is found, step two can be performed to identify it and conduct subsequent data interaction.

[0108] After the networking is successfully completed using the aforementioned networking method, the upper-level control module can obtain the number of currently identified valid energy efficiency terminal slaves through the energy efficiency terminal host, read the data from the energy efficiency terminal slaves, or send control parameters to the energy efficiency terminal slaves.

[0109] At this point, after the energy efficiency terminal host finishes writing the parameter command, it can extract a 6-byte address code from the command and check if this address code exists in the registered file information. If it exists, it indicates that it is a valid energy efficiency terminal slave. The host establishes a connection with the energy efficiency terminal slave via Bluetooth and enters the transparent point-to-point mode to forward the write parameter command. If a reply frame is received from the energy efficiency terminal slave, the host forwards the reply frame to the upper-level control module and disconnects the Bluetooth connection with the energy efficiency terminal slave. If no reply frame is received, the host reports that the energy efficiency terminal slave did not reply to the upper-level control module. If the address code does not exist in the registered file information, the process exits.

[0110] The networking method in this embodiment can be applied to scenarios where energy efficiency terminal slaves connect to multiple energy efficiency terminal hosts, and the energy efficiency terminal slaves are not fixed to be online or offline.

[0111] In another embodiment, if all energy efficiency terminal slaves support Bluetooth communication, and the upper-layer control module specifies the number of energy efficiency terminal slaves to be networked, and the number of energy efficiency terminal slaves is fixed within the coverage area of ​​the energy efficiency terminal host's Bluetooth signal, then the data reading and networking of the energy efficiency terminal slaves can be achieved through the following networking method, which may include the following steps.

[0112] Step 1: In response to the networking information from the upper-layer control module, search for multiple energy efficiency terminal slave devices and record the names of the target slave devices that match the preset naming rules. These preset naming rules are prefixed with ZT + 12-bit encoding. This networking information indicates that the energy efficiency terminal host is networking based on the set number of wireless serial numbers of the energy efficiency terminal slave devices. In this scenario, the upper-layer control module does not need to send the slave device addresses of the energy efficiency terminal slave devices to be networked to the energy efficiency terminal host; it only needs to send the number of energy efficiency terminal slave devices to be networked. Since there is a one-to-one correspondence between the energy efficiency terminal slave devices and their wireless serial numbers (Bluetooth serial numbers), the number of energy efficiency terminal slave devices is also the number of wireless serial numbers. Networking is achieved using this number of energy efficiency terminal slave devices.

[0113] Step 2: Obtain the target wireless serial number corresponding to the energy efficiency terminal slave device based on the target slave device name, and obtain the unique code of the energy efficiency terminal slave device based on the target wireless serial number, that is, convert the target wireless serial number into a 6-byte address code.

[0114] Step 3: Set the number of identifications n to a preset initial value, such as 0. Establish a wireless connection with the corresponding energy efficiency terminal slave device according to each target wireless serial number and send a frame to read device information.

[0115] Step 4: If a response frame is received from the energy efficiency terminal slave, the file information of the energy efficiency terminal slave is established according to the response frame, and the number of identifications is increased according to the preset step value.

[0116] The information in this file may include the type of energy efficiency terminal slave device, the quality of the communication signal, etc. If the preset step value is set to 1, the number of identifications is n+1, and so on, until all energy efficiency terminal slave devices recorded have been identified.

[0117] Step 5: If the final number of identified devices is the same as the number of wireless serial numbers of the set energy efficiency terminal slave devices, the networking is completed and the result of networking completion is fed back to the upper-level control module; otherwise, the result of inconsistent numbers is fed back to the upper-level control module to indicate that networking has failed.

[0118] In addition to Bluetooth communication, the energy efficiency terminal host in this embodiment can also network with the energy efficiency terminal slave via RS485 communication. In this scenario, the upper-level control module can achieve networking by sending the file information of the energy efficiency terminal slave that needs to communicate. This networking method may include the following steps.

[0119] Step 1: In response to the networking information from the upper-level control module, set the identification quantity n to a preset initial value, such as 0; this networking information is used to characterize the energy efficiency terminal host to form a network based on the received file information of the energy efficiency terminal slave. The file information may include the unique code of the energy efficiency terminal slave, and the networking information may also carry the number of energy efficiency terminal slaves to be networked.

[0120] Step 2: Generate a read device information frame based on the unique code of each energy efficiency terminal slave and send it to the corresponding energy efficiency terminal slave via RS485 bus.

[0121] Step 3: If a response frame is received from the energy efficiency terminal slave, the number of identifications is increased according to the preset step value, and it is recorded that the communication with the energy efficiency terminal slave is normal and the communication mode is bus communication.

[0122] If the preset step value is set to 1, then the number of identifications is n+1, and so on, until all energy efficiency terminals to be networked are identified.

[0123] Step 4: If the final number of identified devices is the same as the number of energy efficiency terminal slaves to be networked, the network is completed and the result of the network completion is fed back to the upper-level control module; otherwise, the result of the inconsistent number is fed back to the upper-level control module to indicate that the network has failed.

[0124] Understandably, if RS485 fails to form a network due to a fault, it can still form a network by searching for Bluetooth, thereby improving the success rate of network formation and expanding application scenarios.

[0125] Therefore, if no response frame is received from the energy efficiency terminal slave in step three, the energy efficiency terminal slave can be searched for based on its unique code in the file information.

[0126] If the energy efficiency terminal slave is still not found, the communication abnormality of the energy efficiency terminal slave can be recorded in the file information, and the number of identifications can be increased according to the preset step value, that is, the number of identifications n+1; if the energy efficiency terminal slave is found, a Bluetooth connection is established with the energy efficiency terminal slave and a read device information frame is sent; the read information frame carries the unique code of the energy efficiency terminal slave.

[0127] If a response information frame is received from the energy efficiency terminal slave, the file information of the energy efficiency terminal slave can be updated according to the response information frame, the communication with the energy efficiency terminal slave is recorded as normal, and the identification number is increased according to the preset step value, that is, the identification number n+1; if no response information frame is received from the energy efficiency terminal slave, the communication of the energy efficiency terminal slave is recorded as abnormal, and the identification number is increased according to the preset step value, that is, the identification number n+1. After all energy efficiency terminals to be networked have been identified, step four is continued.

[0128] In this embodiment, the energy efficiency terminal host and the energy efficiency terminal slave can simultaneously support Bluetooth communication and RS485 communication. There is no need to set the slave address. Networking and data interaction are carried out by Bluetooth search, specified number of Bluetooth communication methods, and Bluetooth or RS485 specified file methods. It can adapt to various communication scenarios, reduce the time for on-site configuration and debugging, and broaden the application scenarios of the energy efficiency terminal.
