Abstract
The invention discloses a GSM-based remote alarm method and device. The method is as follows: simulating parameters of a group of sensors which are in a sensor unit and used for measuring different simulating parameters of a system, are converted into digital parameters and sent to a DSP control unit through an A/D conversion unit and the DSP control unit analyses the operation state of the system; and when an abnormal condition occurs to the operation state of the system, the DSP control unit sends the signals to a GSM network through a GSM module and the GSM network sends the abnormal operation state of the system to a handset of a monitoring person so that GSM-based remote alarm is completed. The GSM-based remote alarm method and device reduce the manufacturing cost and operation cost of the remote alarm system and have the advantages of being rapid and convenient and are especially suitable for a system which needs monitoring and alarm for 24 hours around the clock and thus monitoring personal does not need to watch over on site all the time and can carry a handset and receive alarm information of the system and system state parameter information at any place and deal with the information timely. Therefore, the method and device are high in practicality.

in preceding method, described DSP control module is the control module forming take dsp chip as core, comprises external storage and the serial ports being connected with gsm module for storing external command and parameter.
in preceding method, the running status of described DSP control module analytic system is, by external input device, the condition of the normal operation of system is inputted to DSP control module by data interface unit, DSP control module by Sensor monitoring to data and the data of external input device input compare, when Sensor monitoring to data exceed after the data of the normal operation of system, DSP control module decision-making system in abnormal condition.
in preceding method, described data interface unit adopts RS232/485 interface or Ethernet interface.
in preceding method, described external input device is keyboard, single-chip microcomputer or computing machine.
in preceding method, described by Sensor monitoring to data and the data of external input device input to compare be to set the threshold parameter value of reporting to the police, in the time that the data of sensor unit input meet or exceed the threshold parameter value of external input device input, DSP unit controls gsm module sends alarming short message and notifies monitor.
press the device that preceding method forms, comprise DSP control module, one group of input end of DSP control module is connected with sensor unit through A/D converting unit, another group input end of DSP control module is connected with external input device through data interface unit, the serial ports of DSP control module is connected with gsm module, and gsm module is connected with mobile phone wireless through GSM network.
in aforementioned means, described sensor unit comprises one group of sensor, and the each sensor in one group of sensor is all connected with DSP control module through A/D converting unit.
compared with prior art, the present invention is by global system for mobile communications (Global System of Mobile communication, be called for short GSM) be applied to the remote alarms of automatic control system, GSM is a kind of mechanics of communication of technology maturation, there is connection speed very fast, meet user online, participate in the general network behaviors such as video conference, receiving and dispatching mail, have that wide area covers, the advantage such as charging, high-speed transfer according to quantity.When control system goes wrong, can warning message and system status parameters information be sent on monitor staff's mobile phone by GSM, no matter monitor staff at the earth Anywhere, can obtain warning message in the very first time, and alarm velocity is fast.If this remote alarming system based on GSM is connected with existing supervisory system, can also realize the long-range transformation and upgrade to existing system, there is good extendability.The present invention has reduced cost of manufacture and the operating cost of remote alarming system, has rapidly advantage easily, is particularly suitable for needing 24 little systems of uninterruptedly carrying out monitoring alarm.Always on duty at the scene without monitor staff, monitor staff can carrying mobile phone warning message and the system status parameters information of receiving system anywhere, and handle it in time.There is very high practicality.
