Anti-losing device of tour group

Abstract

The invention relates to an anti-losing device of a tour group. The device comprises a host and multiple slaves. The host communicates with the slaves through Zigbee. The host comprises a power supplyswitch, a microprocessor, a clock module, a power supply circuit, a buzzer, a vibration motor, an LED module, a filter and a ceramic antenna. Each slave comprises a power supply switch, a microprocessor, a clock module, a power supply circuit, a buzzer, a vibration motor, an LED module, a filter and a ceramic antenna. The microprocessor of the host judges the distance between the host and the slaves according to time delays of communication signals generated and sent by the microprocessors of the slaves. The microprocessors of the slaves judge the distance between the slaves and the host according to time delays of communication signals generated and sent by the microprocessor of the host, and give out warnings according to the distance. According to the invention, the device is small insize, portable, far in wireless communication distance and easy to manage; electricity is saved; and the device can be used by dozens of people and provides the active order and request sending functions.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to an anti-scattering device for tour groups. Background technique [0002] The Internet of Things refers to a huge network formed by combining various information sensing devices to collect in real time any required information such as objects or processes that need to be monitored, connected, and interacted, and combined with the Internet. Its purpose is to realize the connection between things and things, things and people, and all things and networks, so as to facilitate identification, management and control. [0003] ZigBee is a cheap low-power Internet of Things networking technology. Based on this technology, the present invention develops a tour group anti-scattering device with rich functions, suitable communication distance and long standby time. [0004] In the prior art, the anti-scattering products for tourist groups are either one-to-one traction ropes...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the anti-scattering products for tourist groups are either one-to-one traction ropes, which are not suitable for tour groups with more than a dozen or dozens of people, and are expensive, or Bluetooth anti-lost stickers for anti-lost, The number of mounts is small, the communication distance is short, and the price is generally expensive

None of the tour group anti-scattering devices in the prior art can provide a tour group anti-scattering device with rich functions, long communication distance, and convenient management of tour groups
