The program mainly uses ad-hoc network technology, combined with locator, identification card and card reader equipment, and uses ad-hoc network wireless communication technology to transmit positioning and identity information to the base station, and the base station uploads the received wireless information to the background monitoring center , According to the regional information set in the software system to analyze the location of personnel to achieve positioning. So as to realize the functions of identity recognition, location tracking and trajectory query of people in the building.
The GW10-XXX series of Xiamen Guangkong's self-organizing network equipment is a wireless communication technology similar to Bluetooth, but the transmission distance is larger (the visible transmission distance is up to 10KM). Anyone who understands wireless communication knows that various wireless communication technologies are a communication method that uses the characteristics of electromagnetic wave signals to propagate in free space for information exchange. Ad hoc network is no exception. It uses the internationally universal 433MHZ frequency band for wireless communication, and the communication technology of ad hoc network adopts the cellular ad hoc network communication method.
The main features of the GW10-XXX series of Xiamen Guangkong's self-organizing network equipment are low power consumption, low cost, low speed, short distance, support for a large number of nodes, support for relay, support for encryption, and fast speed. Therefore, as a short-distance wireless communication technology, the ad hoc network has very strong applicability in the field of short-distance transmission due to the convenience of its network construction.
1. System designThe system design mainly uses the intranet transmission function of the GW10-XXX series of communication protocols. In this system, the routing nodes of the GW10-XXX series are installed in the stairway or elevator room of each floor of the building, and play the two-way data transmission of uploading and control. Features. In each floor of the corridor, you can customize a certain amount of locators and card readers to collect personnel location information, and connect to the GW10-XXX series routing nodes through RS485. Each person’s identification card continuously uploads identity information and location information, and then GW10-XXX series router nodes upload personnel information in real time to the building management center, and the management center passes GW10-XXX series nodes and other building management centers in the park. The GW10-XXX series of nodes then form a relatively long-distance GW10-XXX series self-organizing network that is free of traffic charges. Then upload the data to the park computer room management center, and finally through the back-end personnel positioning system, access control system, identity recognition system and other system software, real-time positioning and analysis, recording, and statistical storage of the uploaded data can be used for the internal personnel of the entire park building. Positioning management.
Through this design scheme, the scheme system can be widely used in various places such as office buildings, work plants, campuses, hospitals, communities, and nursing homes. The system can also expand the real-time management of indoor valuable assets, important equipment, and confidential files.
