Problems solved by technology

Since the tag transmission frequency of the existing personnel positioning system is fixed, and the regular transmission method is generally used to communicate with the supporting card reader, when there are too many electronic tags near a certain card reader in the mine, the wireless data transmission conflict is very serious, thus Serious problems that lead to missed reading of electronic tags

Embodiment Construction

[0034] The electronic tag is mainly composed of a single-chip microcomputer U2, a radio frequency transceiver chip U1, an antenna ANT1 and a power supply U3. The oscillator pin OSC1 of the single chip microcomputer U2 is connected to the 1 pin of the crystal Y2, and the oscillator pin OSC2 is connected to the 3 pin of the crystal Y2. One end of the capacitor C14 is connected to pin 1 of the crystal Y2, and the other end is grounded. One end of the capacitor C9 is connected to pin 3 of the crystal Y2, and the other end is grounded. The pins 2 and 4 of the crystal Y2 are grounded, and the pin 3 is connected to the 3.3V power supply through the resistor R5.

[0035] The reset pin MCLR of the microcontroller U2 is connected to the resistor R4, and the resistor R4 is connected to the resistor R3 and the capacitor C8. The other end of the resistor R3 is connected to the 3.3V power supply, and the other end of the capacitor C8 is connected to the ground.

Abstract

The invention pertains to the manufacturing technology field of a miner management system, which is a method for personnel to wear (or equipment to install) electric labels and self organizing network; the electric label comprises a singlechip (1), a wireless radio frequency transceiver chip (1), an antenna (3) and a power (4). The invention is characterized in that: the electric label can realize wireless communication with a matching reader to report ID information; in addition, the electric labels can communicate with each other and automatically organize network; after network organization, only group leader is demanded on communicating information with the reader, realizing group identification. The electric label employs the method of organizing network to report data collectively, which reduces the data amount of a public communication channel, thus decreasing the sending-conflict possibility of wireless data and improving the identifying efficiency of a plurality of electric labels being sent together.

Description

technical field [0001] The invention relates to an electronic tag worn by personnel for identification, in particular to an electronic tag used for identification in a mine personnel management system and an ad hoc network method thereof. Background technique [0002] The safety of underground personnel is a key concern in modern mine production. Many modern mines are equipped with personnel positioning management electronic tags, which are used for real-time positioning, monitoring and dispatching of underground personnel's activities. Since the tag transmission frequency of the existing personnel positioning system is fixed, and the regular transmission method is generally used to communicate with the matching card reader, when there are too many electronic tags near a certain card reader in the mine, the wireless data transmission conflict is very serious, thus Serious problems that lead to missed reading of electronic tags.
