Problems solved by technology

[0026] Once the wrong code of the home wireless device occurs, it is difficult for the home user to troubleshoot and deal with it himself. Generally, he will complain to the operator and ask the service personnel to come to solve the problem, which increases the operation and maintenance cost of the home IoT business.

Embodiment Construction

[0044] One of the characteristics of wireless signal transmission is that the signal strength decreases with the increase of the distance. In addition, the wireless signal will also have a relatively large attenuation when passing through solid obstacles, and the link loss will increase. For example, the signal will generally lose after passing through a wall. About 15 ~ 30dBm. That is, for wireless signals, the closer the transmission distance, the fewer obstacles on the transmission path, and the smaller the transmission link power loss; conversely, the farther the wireless signal is transmitted, the more obstacles are on the transmission path, and the greater the transmission link power loss .

[0045] For a signal from a wireless device in one home to reach a wireless device in a neighboring home, it needs to pass at least one wall and travel a certain distance. Therefore, for the same transmitting device, the wireless signal strength received by the wireless device close...

Abstract

The embodiment of the invention discloses a method, a system and a device for avoiding wrong pairing of home wireless equipment. The method includes: the wireless device receives a code pairing message, the code pairing message carries the transmission power of the code pairing message; the wireless device measures the receiving power of the code pairing message, and reads the code pairing message In the transmission power, calculate the power loss according to the transmission power and the reception power, and judge whether the power loss is within the predetermined threshold range. If so, determine that the wireless device that sent the code pair message is a trusted device, and continue Otherwise, it is determined that the wireless device sending the code pairing message is an untrusted device, and the code pairing fails. The application of the present invention can avoid the problem of wrong code matching, and save the operation and maintenance cost of the Internet of Things business.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and device for avoiding code error of home wireless equipment. Background technique [0002] The Internet of Things is an important development direction in the current communication field. The development of the Internet of Things cannot be separated from hundreds of millions of home users. At present, there have been applications for the home Internet of Things, which are based on the existing TD wireless landlines and home gateways, by adding short-distance wireless transceiver modules, and installing door sensors, smoke detectors, and infrared alarms installed in the home. Security sensors and various home appliances are connected to the Internet, so that remote real-time monitoring and early warning of information such as illegal break-in, smoke, fire, and gas leakage can be realized, and home appliances can also be remotely controlled and st...
