Terminal address allocation method and system

Abstract

The invention relates to a terminal address allocation method, which comprises a host and a plurality of terminals, and is characterized in that the host comprises a unique ID number, and each terminal is provided with an interaction element; the method comprises the steps that 1, the host broadcasts an address setting command, wherein the address setting command comprises a new address configuredto a terminal; 2, a user selects one terminal from the terminals with the new addresses to be set, the user operates the interactive elements on the selected terminals to generate a signal to enablethe terminals to respond to the address setting command, the new addresses contained in the address setting command are stored as the new addresses of the terminals, and then the new addresses are responded to the host to be set, and the new addresses take effect; 3, the host is used for storing the new address and the terminal model allocated this time; and 4, every time address setting is completed, the serial number of the terminal is increased by one time, and the step 1 is returned to re-execute the address allocation step until all the terminals are allocated to new addresses. The methodhas the advantages of flexible address configuration, simple operation and the like.

Description

technical field [0001] The invention relates to a terminal address allocation method and system, belonging to the field of terminal address code allocation. Background technique [0002] In the era of the Internet of Things, various wireless terminals are more and more widely used. For wireless terminals with FSK and GFSK communication modes in the 433MHz, 915MHz, and 2.4GHz frequency bands, point-to-point or point-to-multipoint time-division multiple access methods are mostly used for communication. , a corresponding address needs to be set between the control host and the wireless terminal. The address of the wireless terminal that can access the control host is mostly directly burned into the wireless terminal when it leaves the factory. The problem caused by this method is: once the control host or wireless terminal in the system fails and needs to be replaced, it is necessary to contact the manufacturer, and the manufacturer will burn the address into the new wireless ...

Problems solved by technology

The problem caused by this method is: once the control host or wireless terminal in the system fails and needs to be replaced, it is necessary to contact the manufacturer, and the manufacturer will burn the address into the new wireless terminal or control host to complete the replacement, or The equipment manufacturer provides a burning tool, and the customer can burn the address of the wireless terminal or the control host by himself, which is very inconvenient to operate.

The two technical solutions disclosed above are to assign instructions through broadcasting, and then assign communication addresses according to the feedback confirmation code or device identification. The problems are: 1. After receiving the address assignment instructions, multiple air conditioner slaves respond simultaneously. For the address allocation command, the host must first make a conflict judgment. If there is no conflict, the communication address will be allocated. If there is a conflict, an invalid response notification will be sent to multiple devices. Therefore, the address allocation process is repetitive, complicated and time-consuming; 2. Address configuration The node allocates the device node address code according to the received confirmation code. During the allocation process, the address configuration node cannot predict the response sequence of the device node, so the allocation of the address code is random, and the device node address code cannot be configured in an orderly manner according to actual needs. At the same time , when the address configuration node broadcasts the confirmation code and the address code of the device node, all device nodes in the same system will receive the address allocation frame and verify it. If the system has 100 device nodes, each device node must receive one hundred The second address assignment frame is verified, but only one of them is assigned to the device node. Therefore, the broadcast address assignment frame is used, and each device node verifies and checks by itself, which increases the resource consumption of the device node.
