Android smart phone based GPRS (general packet radio service) network centralized control five-prevention locking system

Abstract

The invention discloses an android smart phone based GPRS (general packet radio service) network centralized control five-prevention locking system. The system can well achieve real-time performance of a traditional off-line five-prevention locking system and solve the problems of inconvenience in installation and complexity of accessory mechanisms of an on-line five-prevention locking system. At present, a computer key is a part of a microcomputer five-prevention locking system produced by each company in a supporting manner, so that universality is poor. In addition, an original computer key operating screen is small, operation and communication modes are single, and intelligentization cannot be realized. However, an android smart phone is good in universality, and the system is open-source, easy for function extension, large in operation screen, high in operation smoothness, good in user experience and diversified in communication modes, can have a database function and the like besides, and is good in applicability and extensibility in general.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a GPRS network centralized control five-proof locking system based on an Android smart phone. Background technique [0002] The five defenses in the power system refer to: prevent wrong opening and closing of the circuit breaker; prevent load opening and closing of the isolating switch; prevent charged from hanging (closing) the grounding wire (grounding switch); (isolating switch); to prevent stray into live intervals. [0003] There are four main types of conventional anti-misoperation locking methods: mechanical locking, program locking, electrical interlocking and electromagnetic locking. These locking methods have played an active role in the error prevention work. After years of use and operation tests, the advantages and disadvantages of various traditional locking methods have been fully demonstrated. [0004] Mechanical locking is to use mutual restraint and lin...

Problems solved by technology

[0012] The technical solution adopted by the present invention to solve its technical problems is: based on the universality of Android smartphones and the open source of the Android system, the problems of poor universality of computer keys and inconvenient expansion of computer key functions can be well solved; The advanced WIFI and Bluetooth communication modules can solve the problem of the singleness of traditional communication methods and the inconvenience of network expansion; and the use of the existing GPRS network can solve the non-real-time nature of lock operation and the inability to obtain the actual location of the site in real time; And expand the transmission range, and ultimately save costs
