One Kind The Message Notity Module Which Uses In The Switchgear Monitoring

Conventional switchgear equipments realize the function of distribution, controlling, protection and monitoring by circuit breakers, contactors, relay, control appliances,and electric meters, etc.The switchgear of this kind is often furnished with several dozen or more simulation indicator instruments and a large number of relays, bringing great inconvenience to production, storing and maintaining. Meanwhile, it is mainly operated directly by manual work, so it is unable to realize computer management, and even more for complex logic control. For this, we have designed and realized an Message Notity Module.The Message Notity Module is an Module which send messages make use of GSM(Global System for Mobile Communication). When the circuit breakers alarm or field it will be send messages which include the reason of the alarm, the time it happened and the location to enactmented mobile phones so that users could deal with it in time. Message Notity Module could be connected to one or more communication equipments (Max. 16 units) through the communication mode to make up an independent system. It could operate without connecting to the computer, and could send messages to more than one mobile phones (Max. 10) once the pre-set events happen to the field device, so that users could deal with it in time. Users could configure the Message Notity Module through configuration software, for example, communication parameters, mobile phone No., device addresses, device names and alarm type etc. The different from others is it could operate without connecting to the computer.This text mainly discusses the technological details of implementation of this system from the respects of the hardware design and software design on the basis of analysis on the designning plan of the system, and stresses several key technology difficult points and states their solutions.The system has greatly succeeded in improving the dependability of the distribution control, and has realized the possibilities of unmanned-on-duty and remote-meter -checking, which has greatly saved the cost of manpower. This system has very high economic worth.
