Problems solved by technology

If the public frequency band is like the electromagnetic spectrum for personal use, there is no similar control or alternative configuration measures, confusion may occur, for example, there are no frequencies that aircraft can specifically use for air traffic control, and signals from amateur radio operators interfere with air traffic control signals, Make it impossible for the pilot to land the plane normally

Embodiment Construction

[0011] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0012] During the use of Bluetooth technology, people found that although Bluetooth technology has many advantages, there are still many defects. For the fields of industry, home automation control and industrial telemetry and remote control, Bluetooth technology is too complicated, with high power consumption, short distance, and too small a network scale. In industrial automation, the demand for wireless data communication is becoming stronger and stronger, and for industrial sites, this wireless transmission must be highly reliable and resistant to various electromagnetic interferences in industrial sites. Therefore, after people's long-term efforts, ZIGBEE officially came out in 2003. In addition, ZIGBEE has used Home RF Lite, a communication protocol for home networks that it has studied before.

[0013] At present, during rush hours in the mornin...

Abstract

The invention relates to a wireless signal triggering method, and the method comprises the steps: providing a wireless signal triggering system which is used for carrying out the targeted detection ofthe number of persons in each region in a subway carriage, so as to determine whether a person flow request signal needs to be transmitted or not, so as to guarantee the average number of persons ineach region.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a wireless signal triggering method. Background technique [0002] Light, color, AM and FM broadcasting, and many electronic devices use the radio spectrum. The radio spectrum frequencies that can be used for communication are considered public property and will be managed by national agencies, such as the Federal Communications Commission in the United States and the United Kingdom. Ofcom, these bodies define who can use which frequencies, and for what purpose. If the public frequency band is like the electromagnetic spectrum for personal use, there is no similar control or alternative configuration measures, and confusion may occur. For example, there are no frequencies that aircraft can specifically use for air traffic control, and signals from amateur radio operators interfere with air traffic control signals. This prevents the pilot from landing the plane normally. Th...
