Background
KNX is the only open international standard in the field of household and building control, and is developed by combining European three bus protocols EIB, BatiBus and EHS. The KNX standard is currently approved as the European standard (CENELECEN50090& CENEN13321-1), the International Standard (ISO/IEC14543-3), the American Standard (ANSI/ASHRAE135) and the Chinese instructional Standard (GB/Z20965), which have become the national Standard instructional documents for "HBES technical Specification-residential and building controls". The KNX protocol is based on EIB, gives consideration to the physical layer specifications of BatiBus and EHS, absorbs the advantages of configuration modes in BatiBus and EHS and the like, and provides a complete solution for home automation and building automation. KNX possesses a design and test tool (ETS) that can be independently designed and tested by the manufacturer; providing a plurality of communication media (TP, PL, RF and IP); a plurality of system configuration modes (A, E, S modes) are provided. The KNX bus is a system independent of the manufacturer and the field of application. The lighting, shading/shutter, security system, energy management, heating, ventilation, air conditioning system, signal and monitoring system, service interface and building control system, remote control, metering, video/audio control, large-scale household appliances and the like of the home and building are controlled through the KNX bus system. The intelligent home utilizes advanced computer technology, network communication technology and comprehensive wiring technology, integrates individual requirements according to the principle of human engineering, organically combines various subsystems related to home life such as security protection, light control, curtain control, gas valve control, information appliances, scene linkage, floor heating and the like, and realizes 'people-oriented' brand-new home life experience through networked comprehensive intelligent control and management.
The KNX equipment refers to a system module controlled by a KNX bus, such as a KNX light control module, a KNX curtain control module, a KNX air-conditioning gateway and the like.

The ETS is special KNX debugging tool software, needs to be purchased from a KNX association, runs in a Windows operating system of a computer, and is used for designing and configuring the KNX intelligent home and building control installation system. If the KNX equipment needs to be modified, a professional KNX debugging engineer is required to go to the site to modify the configuration. This solution is relatively demanding for commissioning personnel and requires the use of ETS tools. In addition, because the modification of KNX equipment in traditional KNX system needs KNX debugging engineer to carry out the on-the-spot configuration of revising, consequently, KNX equipment can only come on-line one by one, and the efficiency of going on-line of KNX equipment is low.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It should be noted that the terms "first \ second \ third" related to the embodiments of the present invention only distinguish similar objects, and do not represent a specific ordering for the objects, and it should be understood that "first \ second \ third" may exchange a specific order or sequence when allowed. It should be understood that the terms first, second, and third, as used herein, are interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in other sequences than those illustrated or otherwise described herein.
In this embodiment, a KNX node auto-discovery method is provided, and fig. 1 is a flowchart of the KNX node auto-discovery method according to an embodiment of the present invention, as shown in fig. 1, the flowchart includes the following steps:
and S101, automatically configuring the first KNX node or configuring first address information through a dial switch.
In the above embodiments, the KNX nodes include, but are not limited to: KNX hardware equipment and KNX software equipment. The KNX hardware devices differ from KNX software devices in that: the KNX hardware device refers to a physical hardware device, and the KNX software device refers to a logically divided KNX device, for example, in some cases, the hardware resources of the KNX hardware device may be allocated to be logically divided into a plurality of KNX software devices.
The automatic address information configuration of the KNX node refers to that a program capable of automatically configuring address information is preset in the KNX node, when the KNX node is powered on, the address information is generated according to a preset rule, and the address information is configured to be the address information of the KNX node.
The KNX node configures the address information through the dial switch, namely the dial switch of a multi-position switch is configured on the KNX node in advance, and a user only needs to dial each position switch of the dial switch to realize the configuration of the address information of the KNX node. There may be a maximum of 64 KNX nodes on the same KNX line, as defined by the relevant KNX standard, and therefore, in this case, the number of switching bits of the dial switch is preferably set to 6 bits.
The address information comprises but is not limited to addresses required by the KNX node online and related parameter information; the relevant parameter information can be configured in advance, and the address in the address information is automatically generated by the KNX node. Addresses in the address information include, but are not limited to: physical Address (PA) and Group Address (GA). The physical address is used for reflecting the topological position of the KNX node in the KNX network, and the physical address can be composed of a domain address, a line address and a device address, and the physical address in the same KNX system should be unique. The group address is a function-related address, which may not be unique in a KNX system, and the same KNX node may have one or more group addresses.
And S102, the first KNX node receives a node searching message broadcasted on the KNX bus, wherein the node searching message carries second address information of the second KNX node.
In this embodiment, in order to enable other KNX nodes in the KNX system to know the address information of the second KNX node and instruct the other KNX nodes in the KNX system to report the address information of the second KNX node, the second KNX node may broadcast a node search message to the KNX bus, where the node search message carries the second address information of the second KNX node. And after the first KNX node is electrified, the first KNX node continuously monitors the KNX bus, and when the KNX bus broadcasts the node search message, the node search message on the bus is received and analyzed to obtain second address information of a second KNX node serving as a host, wherein the second address information indicates the position of the information reported by the first KNX node.
It should be noted that the second KNX node in this embodiment may be any one of the KNX nodes in the KNX system, or may be a KNX node serving as a master node in the KNX system. The second KNX node is preferably any one KNX node in the KNX system, and the second KNX node serves as a temporary KNX host in the node online process of the KNX system, so that the node search message of the KNX node is conveniently initiated without specially using the master control node to initiate the node search message. Wherein, can dispose an automatic button of going on the line on the second KNX node, after the user pressed the automatic button of going on the line on the second KNX node, the second KNX node regarded oneself as the KNX host computer, broadcast node search message to the KNX bus.
In addition, the second address information of the second KNX node may also be configured by automatic configuration or by a dial switch.
And step S103, the first KNX node reports the first address information to the second KNX node according to the second address information.
In this embodiment, after acquiring the second address information of the second KNX node serving as the host, the first KNX node may send a message to the second KNX node through the KNX bus, where the message carries the first address information of the first KNX node.
In the above embodiment, all KNX nodes in the KNX system send messages in compliance with the KNX protocol specification. For example, the KNX node transmits information through a message, the KNX node receives a response after sending the message, and the sending device usually sends the message repeatedly three times if receiving a reception error (NAK) confirmation; if the KNX node receives the confirmation that the bus is occupied (BUSY), the KNX node sending the message will try to send the message again after waiting for a random short time slot; if the KNX node sending the message does not receive the ACK confirmation, the message is repeatedly sent at most three times, and then the sending request is stopped. The KNX system applies CSMA/CA (carrier sense multiple access/collision avoidance) and message priority to control medium access.
In the related art, the configuration of the KNX system has two configuration modes, one is a system Mode (S-Mode) and one is a simple Mode (E-Mode). Wherein, S-Mode means that the configuration Mode is to realize complex building control functions for a well-trained KNX installer. E-Mode means that the configuration Mode is for basic KNX trained installers. In any configuration mode in the related art, the ETS tool is required to be used, and a certain debugging tool using capability is provided.
Different from the related art, in this embodiment, after the first KNX node is configured automatically or the first address information is configured through the dial switch through the above steps, the second address information of the second KNX node is obtained from the node search message broadcast on the KNX bus, and then the first address information is reported to the second KNX node, so that the on-line of the first KNX node can be realized. According to the technical scheme, the address information of the first KNX node is not required to be configured through a debugging tool, and the address information can be automatically configured through the first KNX node or manually configured through a dial switch. When a large amount of KNX nodes need to be on line, the KNX nodes only need to be connected into the KNX bus, after the KNX nodes are powered on, the address information of the KNX nodes is automatically reported to the second KNX node according to the steps, the on-line of the KNX nodes is completed, the problem of low on-line efficiency of the KNX equipment in a KNX system in the related technology is solved, and the on-line efficiency of the KNX equipment is improved.
Fig. 2 is an interaction flowchart of a KNX node auto-discovery method according to an embodiment of the present invention, as shown in fig. 2, in one embodiment, after a first KNX node reports first address information to a second KNX node according to second address information, the second KNX node receives the first address information; the second KNX node sends the first address information to the application program so that the application program can generate an icon of the first KNX node on an interface of the application program.
The client of the application program is preferably arranged in a user terminal held by a user, and the server of the application program is preferably arranged on a wireless local area network or the Internet. Preferably, a communication node is configured on the KNX bus, the communication node communicates with the server of the application program through a wireless local area network or the internet, and the server of the application program communicates with the client of the application program through the wireless local area network or the internet, so that an icon of the KNX node on line in the KNX system is displayed in a user terminal held by a user.
The configuration files of the KNX nodes can be configured in advance in the application program, the description information is configured in advance for each configuration file, a user can select one KNX node through the icon of the KNX node displayed in the interface of the application program, the description information of the configuration files is referred, and the configuration files of the pre-configured KNX nodes are used for configuring the selected KNX node, so that the problems that the KNX node needs a special debugging tool to be configured and the user experience is poor in the configuration process are solved.
With reference to fig. 2, since the address information of the KNX nodes added to the KNX system is configured automatically by the respective KNX nodes or configured by the dial switches, there may be a case where two KNX nodes in the same KNX line have the same address, so that address collision cannot normally transmit and receive messages. In order to avoid the problem, after the first KNX node reports the first address information to the second KNX node according to the second address information, the second KNX node receives the first address information; the second KNX node judges whether address conflict exists according to the first address information; and under the condition that the address conflict exists, the second KNX node sends an address conflict message to the address indicated by the first address information. The address conflict message is used for indicating that the address information of the current KNX node with the first address information conflicts with other KNX nodes in the current KNX system, and an address conflict elimination program needs to be executed.
Thereafter, a third KNX node receives the address collision message, wherein the third KNX node comprises: the address information is configured as a KNX node of the first address information; the third KNX node judges whether the first address information can be reconfigured or not according to the address conflict message; under the condition that the address information can be reconfigured, the third KNX node reconfigures the first address information into third address information and sends the third address information to the second KNX node; and under the condition that the address information cannot be reconfigured, the third KNX node sends the first address information to the second KNX node.
In the above embodiment, the third KNX node attempts to resolve the address conflict by reconfiguring the address information, that is, when the address of the third KNX node is automatically configured by the third KNX node, a random address can be obtained by reconfiguring, so as to resolve the address conflict; when the address of the third KNX node is configured by the dial switch, the third KNX node directly resends the first address information to the second KNX node in this case, since the third KNX node cannot change the value of the dial switch by itself.
It should be noted that the number of the third KNX nodes is at least two, and the third KNX nodes may include the first KNX node that transmits the first address information, and may further include other KNX nodes.
In one embodiment, the address information received again by the second KNX node as the host, may be all the first address information (i.e., none of the address-conflicting KNX nodes reconfigure address information), may be all the third address information (i.e., none of the address-conflicting KNX nodes reconfigure address information), may be a portion of the first address information, may be a portion of the third address information (i.e., a portion of the address-conflicting KNX node reconfigure address information, a portion of the address-conflicting KNX nodes do not reconfigure address information), at which point, the second KNX node may again determine whether there is still an address conflict between the received address information and the address information of the KNX node that has come on line, if there is still an address conflict, an attempt may be made to send an address conflict message to the KNX node where the address conflict occurred again to perform the address conflict elimination procedure again. For the KNX node with the automatic configuration address information, the problem of address conflict can be finally solved by one or more address conflict elimination programs, but for the KNX node with the dial switch configuration address information, manual intervention is needed. Therefore, in the multiple address conflict elimination procedure, if it is determined that there are two or more address conflicts among several KNX nodes, the second KNX node may send an alarm message to the user, preferably to a client of an application installed on a user terminal held by the user, to notify human intervention to resolve the address conflict. The warning message carries identification information of the KNX node with the address conflict.
The invention will be described and illustrated with reference to preferred embodiments.
In the preferred embodiment, a KNX node auto-discovery method is provided, wherein the auto-discovery is to embed a program in each KNX node. The method comprises the steps that a search command is issued through an addressed KNX node (equivalent to a second KNX node, namely a KNX host), an APP (equivalent to an application program), the search command is forwarded through the KNX host, nodes on all buses receive a search command message and send equipment information to the host, and the VSON (the VSON is in an equipment information format, and each equipment can generate a VSON file) is analyzed by the host according to a received data packet and stored locally. The host can transmit local equipment information to the APP through the PHP interface, and at the moment, the APP interface can generate all KNX node icons. The user can carry out equipment configuration through the APP.
Fig. 3 is a flowchart of the KNX node auto-discovery method according to the preferred embodiment of the present invention, and as shown in fig. 3, the flowchart includes the following steps:
and S301, after the KNX node is powered on, setting the address of the KNX node in a dialing or automatic address allocation mode.
Step S302, selecting one device from all KNX nodes on APP as an automatic discovery host, and broadcasting a search command message to the KNX bus by the host.
Step S303, after receiving the search command message, the device on the KNX bus reports device information to the address of the host, where the device information includes but is not limited to: device type, device address, etc.
And the process of reporting the equipment information by the KNX follows the rules of the KNX protocol, and message conflicts are processed.
Step S304, the host analyzes the equipment information of each KNX node from the received message;
when the KNX nodes conflict in address (the addresses are the same), the solution can be solved in the following two ways:
(1) if the addresses of the two address conflicting KNX nodes are generated by the KNX nodes themselves in an automatic address allocation manner, the host will simultaneously send an address modification message to the KNX nodes (with two KNX nodes) of the same address when receiving the addresses of the two KNX nodes, and after receiving the address modification message, the two KNX nodes: and one or two KNX nodes automatically allocate addresses for the KNX nodes again and report respective equipment information again.
(2) If the addresses of the two KNX nodes with the conflicting addresses are generated by dialing, the host sends an address modification message to the KNX node (with the two KNX nodes) of the address when receiving the addresses of the two same KNX nodes, and the two KNX nodes generating the addresses by dialing still report the equipment information according to the original addresses of the two KNX nodes; after the host receives the equipment information of the KNX nodes reported again, if the address is analyzed to be the same as the address reported last time, or the two KNX nodes are still the same, the two KNX nodes are not allowed to be on line, and the problem is solved by manual troubleshooting.
Step S305, the host sends the equipment information of the KNX node to the APP;
step S306, generating a KXN device icon by the APP interface. Enabling control of the KNX node over the APP.
