GPRS-based digital monitoring and alarm distribution device

Abstract

The invention relates to a digital monitoring and alarm issuing equipment based on GPRS, including: a microprocessor MCU, a GPRS wireless communication module, a digital monitoring signal access module and a control module. The microprocessor MCU is connected with the rest various modules to be responsible for the realization of information processing and business logic; the MCU can timely obtain the abnormal signals which are sent by the field monitoring equipments by the mode of dry contact pulse by the digital monitoring signal access module, and the abnormal signals can be timely sent to a central intelligent control server by the GPRS wireless communication module; the server can do the reaction rapidly, the MCU obtains the control command of the server by the GPRS wireless communication module, a display screen is controlled to display the alarm information by the serial command, or a sound light alarm equipment or a third-party linkage equipment is controlled by the control module. The protocol communication with the link maintenance is carried out between the equipment and the server, so the communication errors and faults can be detected timely; and the equipment can carry out the issuance of various forms of warm information by the control module.

Description

technical field [0001] The invention relates to a GPRS-based digital monitoring and warning issuing device, which is suitable for a remote digital monitoring and warning issuing system. Background technique [0002] The importance of remote digital monitoring in production and life has been gradually recognized and valued by people. In recent years, with the development of wireless communication technology, especially the improvement of mobile communication networks, remote digital monitoring technology has entered a new stage of development; compared with wired communication methods, wireless communication technology is easy to use, low cost, no wiring, no The advantages of establishing a dedicated communication network and good scalability. GPRS (General Packet Radio Service, General Packet Radio Service) is a wireless communication technology based on the existing GSM system. GPRS technology can be connected with TCP / IP communication of Internet network, which provides ...
