WSN-based underground safety monitoring system gateway equipment

Abstract

The invention discloses WSN-based underground safety monitoring system gateway equipment, which comprises a microprocessor unit, a memory unit, a WSN radio-frequency transceiving unit, an Ethernet interface unit, an RFID (radio-frequency identification) unit, a buzzer early warning unit, a voice communication unit and a human-machine interface unit, wherein the microprocessor unit is a gateway core and implements data processing and task scheduling control according to a certain algorithm; the WSN radio-frequency transceiving unit finishes data transceiving of each node of a wireless sensor network; the Ethernet interface unit supplies an interface for communication between the gateway and an Internet network; the RFID unit provides services for underground personnel attendance check and fuzzy positioning; and the buzzer early warning unit and the voice communication unit realize gateway local alarm and IP voice call service between the gateway and a remote server under emergency. Thegateway equipment has the advantages of small volume, light weight and strong function, and can reliably realize the protocol conversion function of a heterogeneous network, provide multiple practical auxiliary services and provide overall guarantee for underground safe production.

Description

technical field [0001] The invention relates to the application field of wireless sensor network technology, in particular to a multifunctional heterogeneous network protocol conversion gateway device based on wireless sensor network technology. Background technique [0002] Timely collection and analysis of various information on mine safety production, timely transmission of production scheduling instructions to every underground work site, especially the timely forecast of underground emergencies and rescue and disaster relief, are the key to ensure mine safety. However, the mine covers a wide range, the environment is complex, and there are many safety monitoring nodes required. Using the existing wired method is not only extremely complicated in wiring, but also high in cost. In contrast, wireless networks are comprehensive in terms of cost, flexibility and practicability. Beyond the wired communication system, it is a practical solution for underground safety monitorin...

Problems solved by technology

However, there are still some deficiencies in the current products and patents, which are as follows: (1) Most of the existing gateway devices have poor processing capabilities and limited storage resources, which cannot meet the needs of high-speed data processing, large-capacity local database storage, and multiple Functional service requirements; (2) Most of the existing gateway devices do not provide a local early warning system, which greatly increases the risk of potential safety hazards leading to major accidents

(3) Most of the existing gateway devices do not have an embedded audio communication system, so that underground personnel cannot conveniently establish voice communication with mine management personnel anytime and anywhere, which brings inconvenience to emergency coordination when emergencies occur; (4 ) Most of the existing gateway equipment does not have a local man-machine interface, which creates great obstacles to the resetting of many environmental variables of the gateway equipment and the real-time understanding of environmental parameters by underground personnel;
