The first communication equipment is used as host equipment, the second communication equipment is used as slave equipment in communication, and the second communication equipment can receive the control command sent by the first communication equipment and execute corresponding control action.
The control module is an independent module, is arranged facing a user, and is provided with an operation panel for receiving a control instruction input by the user through a key on the operation panel or the touch module. The control module is provided with a first Bluetooth module and a bus interface, and is connected with at least one second communication device through the bus interface.
The intelligent terminal is provided with a second Bluetooth module and is used for establishing communication connection with the control module.
The intelligent terminal establishes a bidirectional communication connection with the second communication equipment through the control module and the first communication equipment, and is used for sending a control command to the appointed second communication equipment or receiving information returned by the second communication equipment, and the second communication equipment for establishing the bidirectional communication connection is the transfer communication equipment. Specifically, the intelligent terminal is in Bluetooth communication connection with the control module, the control module can be in bidirectional communication with the relay communication device through a bus, the relay communication device can be in bidirectional communication with the first communication device, and the first communication device can be connected with all the second communication devices, so that communication between the intelligent terminal and any one of the first communication devices can be achieved.
According to the communication network system, a dial switch is not required to be arranged on the substrate of the second communication device, the intelligent terminal is communicated with the control module through the Bluetooth, the intelligent terminal can send the setting information of the second communication device to the control module through the Bluetooth, the control module sends the setting information to the first communication device through the transfer communication device and the first communication device which are connected with the control module in sequence, and finally the target second communication device is set. According to the scheme, the dial switch does not need to be configured for the second communication equipment, the substrate integration design of the second communication equipment is facilitated, the size of a new substrate is smaller, the production efficiency is higher, and the purchasing cost is lower. The dial switch is omitted, the dial switch does not need to be operated during production, misoperation risks are reduced, and production efficiency of the wire body is improved. In addition, read-write control is carried out on the second communication equipment through the intelligent terminal, service personnel work is facilitated, and the manual service cost is reduced.
Because the intelligent terminal is not in direct communication with the second communication devices, and the number of the second communication devices is large, in order to ensure that the intelligent terminal can establish communication connection with all the second communication devices, in this embodiment, preferably, after establishing communication connection between the intelligent terminal and all the second communication devices in the system, the control command includes a data request instruction, the control module performs protocol conversion after receiving the data request instruction and sends the data request instruction to the first communication device, the first communication device sends the data request instruction after the protocol conversion to all the second communication devices in the system, the second communication device retrieves respective configuration information and sends the configuration information to the first communication device, the first communication device sends the configuration information to the control module, and the control module sends the configuration information to the intelligent terminal.
The first communication equipment receives the configuration information sent by the second communication equipment and then stores the configuration information in a cache until the configuration information sent by all the second communication equipment is received, then all the configuration information is packaged and sent to the second communication equipment and the control module in sequence, and the control module carries out Bluetooth protocol conversion and then sends the configuration information to the intelligent terminal for display.
Therefore, the intelligent terminal can acquire dial setting information, function selection information and input/output setting information of all the second communication devices in the system by one key. And then setting different functions for the second communication device with the specified address.
The dial setting also comprises system dial, address dial, capacity dial and model dial. Because the hardware dial switch of the second communication equipment substrate is cancelled, the same effect can be achieved by replacing the hardware dial in a communication transmission mode of Bluetooth data and bus data.
The first communication equipment also comprises a step of judging whether to acquire the configuration information of all the second communication equipment in the system, when the first communication equipment acquires the configuration information of all the second communication equipment in the system, the first communication equipment sends the configuration information to the relay communication equipment, otherwise, the first communication equipment resends the request for acquiring the configuration information to the second communication equipment which does not feed back the configuration information. The scheme needs to ensure that the intelligent terminal can establish communication connection with all the second communication devices in the system.
The control command comprises a data modification instruction and a target address, the target address is the address of the second communication device needing to be modified, the control module receives the data modification instruction and the target address, carries out protocol conversion and sends the data modification instruction to the first communication device, the first communication device sends the data modification instruction after the protocol conversion to the target communication device, the target communication device is the second communication device corresponding to the target address, the target communication device stores modified contents in a cache of the target communication device, and the transmission of the data modification instruction of any second communication device by the intelligent terminal can be achieved.
The relay communication equipment also comprises a step of comparing the address of the target machine with the address of the relay communication equipment after receiving the data modification instruction and the target address after protocol conversion, when the target address has one address and is consistent with the address of the relay communication equipment, the relay communication equipment does not send the converted control instruction to the first communication equipment, the first communication equipment is used as the target communication equipment to directly execute the data modification instruction, and otherwise, the relay communication equipment sends the converted data modification instruction and the target address to the first communication equipment.
For the relay communication equipment, if the set target address is the address of the relay communication equipment, the relay communication equipment can be set directly according to the set information without sending the target address to the first communication equipment for forwarding, so that the communication program and the communication time can be saved.
And when the target addresses are multiple, the target communication equipment sends the received converted control instruction to the first communication equipment, and the first communication equipment sends the control instruction to the corresponding second communication equipment according to the addresses.
When the plurality of destination addresses include the address of the relay communication apparatus, the first communication apparatus may transmit the control command to all the destination addresses, or may transmit the control command to only the destination addresses other than the address of the relay communication apparatus.
In order to feed back the setting state to the operator so as to process the next work in time, in this embodiment, it is preferable that after the target communication device executes the data modification instruction, the modification success information is fed back to the first communication device, and the first communication device feeds back the modification success information to the intelligent terminal through the relay communication device and the control module. The path of the target communication device for sending data to the intelligent terminal is opposite to the path of the intelligent terminal for sending data to the target communication device.
And after receiving the information of successful modification, the intelligent terminal sends a restart control command to the target communication equipment. The output path and manner of the restart control command are the same as those of the aforementioned control command transmission path and manner.
After the target communication device is restarted, the setting instruction stored in the cache of the target communication device is effective, and the information modification is really finished.
When the first communication device and the second communication device communicate with each other, the delayed transmission is performed according to the order from the small address to the large address of the second communication device, and in order to improve the response speed of the communication system during communication, when the control module is connected with a plurality of second communication devices, the second communication device with the smallest address code is used as a relay communication device. The response speed is fastest because the second communication device with the smallest address code delays the shortest time.
It can be understood that, when a plurality of second communication devices are connected to the control module, there should be a step of comparing the coded addresses of the second communication devices, and finding out the second communication device with the smallest address code as the relay communication device.
When the intelligent terminal is in Bluetooth communication connection with the control module, the intelligent terminal is connected with a network according to a preset Bluetooth broadcast protocol, can only identify the Bluetooth module configured on the control module, and is matched with the Bluetooth module through the preset exclusive data bit. Other bluetooth modules (such as bluetooth mobile phone) will be automatically screened out to prevent interference.
The bluetooth broadcast protocol includes: data length bit, Service data bit, UUID bit, Bluetooth version bit, device type bit (for example, 0x01 represents air conditioner), whether encryption bit, Bluetooth device MAC number bit, and CRC check bit are supported. The pairing of the mobile phone and the Bluetooth is realized through the formulated exclusive data bit.
When the intelligent terminal searches a plurality of control modules which can be paired, the intelligent terminal respectively sends action commands to the searched control modules, the control modules which receive the action commands execute the actions, and the action commands are any combination of sound and light actions.
For example, in the pairing process, if the intelligent terminal searches for a plurality of bluetooth modules (respectively corresponding to a plurality of control modules), the special LED lamp in the control module equipped with the bluetooth module can be triggered to flash by long-term pressing of the bluetooth name, so that one-to-one accurate matching can be realized more accurately to prevent connection errors.
A Bluetooth service protocol is formulated, and the Bluetooth module has a read-write bidirectional function. Through the drawn UUID code (0 x0001 for reading and 0x0002 for writing), interaction with the APP is realized, bidirectional data transmission is realized, and data collision is avoided.
The data packet comprises an identification code, a status code, a communication type identification code (01 represents dial information modification, 02 represents function selection and input/output information modification, 04 represents restarting of the first communication equipment and the like), an address code and data information of the second communication equipment, and CRC check bits. During data transmission, reading and writing of data are realized by accepting and identifying different data packet information, and if the data packet information is inconsistent, sending and accepting are failed.
After the special Bluetooth module is configured, the special interaction between the second communication equipment and the intelligent terminal is realized. For example: first, the intelligent terminal searches for the first bluetooth module, and simultaneously searches for the first bluetooth module a and the first bluetooth module B, but we want to connect to the control module 1 at this time. Firstly, pressing a first Bluetooth module B on an interface of the intelligent terminal, finding that an LED lamp of the control module 1 does not flicker, and representing that the LED lamp is not the Bluetooth module of the control module 1. And then pressing the first Bluetooth module A for a long time, finding that the special LED lamp of the control module 1 flickers, and indicating that A is the Bluetooth module of the control module 1. And connecting to A to complete pairing connection. At the moment, the forwarding of different information (including dialing, function selection and the like) is realized through the newly formulated Bluetooth service protocol and the identification of the communication type identification code.
In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
