Problems solved by technology

At the same time, when customers use it, if they accidentally enter the code pairing mode, due to the long distance of radio frequency transmission, it is easy to make the host re-bind. If there is another host at the same time, it is possible that two hosts will be paired at the same time; accident hazard

Embodiment Construction

[0022] Below in conjunction with embodiment, the present invention is further described.

[0023] The present invention is carried out according to the following steps:

[0024] 1. Burn the serial number inside the chip of the remote control

[0025] The chip of the remote control (recommended to use Renesas R7F0C001) burns the 16-bit serial number in the 0x3bfe address inside the chip when burning the program.

[0026] For the relevant interface of the remote control programming program, see image 3 .

[0027] The programming method is as follows:

[0028] The serial number is entered manually, and after a chip is burned, the increment of the serial number is controlled by the increment control value.

[0029] For example: input 0x0000 for the initial serial number, 0x01 for the incremental control, and 0x3bfe for the initial address.

[0030] Start burning, after burning 0x0000 to 0x3bfe inside the first chip, the serial number increases to 0x0001;

[0031] Burn again...

Abstract

The invention relates to a control method and aims to provide a method for short distance code matching between remote controllers and a host in a radio frequency mode, so that code matching operationcan only be performed when the distance between the remote controllers and the host is short enough, and problems caused by remote matching are solved. The technical scheme is characterized in that the method for short distance code matching in the radio frequency mode comprises the steps as follows: 1) a different 16-bit serial number is burnt in a chip of each remote controller; 2) each remotecontroller sends a code matching signal to the host; 3) the host receives the signal and identifies signal strength of the message; if the signal strength value is smaller than 0*10, the distance between the corresponding remote controller and the host is short enough, and the host accepts the code matching signal and performs code matching; if the signal strength value is larger than 0*10, the distance between the corresponding remote controller and the host is relatively long and the host ignores the signal.

Description

technical field [0001] The invention relates to a control method, in particular to a short-distance code matching method between a remote controller and a host computer in a radio frequency mode. Background technique [0002] With the rapid development of the construction industry and the acceleration of scientific and technological progress, various electronic products controlled by remote controllers continue to emerge. In the radio frequency communication mode, in order to achieve the purpose of one-to-one correspondence between the remote control and the host, it is necessary to perform code matching between them. The distance of the signal transmitted by the RF module is relatively far, and only one host can enter the code matching mode during code matching. This method brings a lot of trouble to the factory inspection, and the testing efficiency is very low. If multiple production lines are to be tested at the same time, the distance between the production lines or g...
