Abstract

The utility model discloses a telecontrolling and telemetering device which transfers data through telecom fixed network short message service, the telecontrolling and telemetering data are packed by the format of telecom short message, are modulated through the information telephone FSK of fixed network short message, and are sent to telecom short message service center to forward to the monitoring center. The utility model can transmit data through dialing the special number of short message service center without the telephone number of monitoring center, the data according to the format of short message are sent to the telecom short message server. The utility model is provided with high dialing connection rate, low using cost, format standardization and convenient networking extension, which can be suitable for public security, municipal services, transportation, environmental protection, power, telecommunications, and other industries to carry out centralized telecontrolling and telemetering and remote meter reading of key monitoring points, urban facilities (such as street lamp), computer rooms and base stations, environmental monitoring stations, sewage outfalls,etc.

Description

Adopt the telecommunications fixed network message to realize the device of remote measuring and controlling

Affiliated technical field:

The utility model relates to a kind of environment and equipment operation to remote monitoring point and implements automatic monitoring device, be applicable to that industries such as public security, municipal administration, traffic, environmental protection, electric power, communication are to the concentrated remote measuring and controlling of implementations such as key monitoring point, urban facilities (as street lamp), machine room and base station, environmental monitoring station and sewage draining exit, also can be used for ammeter water meter and gas meter remote meter reading, remote control domestic electrical equipment equipment operation and home alarm etc.

Background technology:

Development along with needs of society and technology, various long-range automatic monitoring monitoring products and application continue to bring out, they are made up of computer (single-chip microcomputer), transducer or other interface circuit, communications module etc. basically, main difference is the communications mode difference that is adopting, adopt wireless mode (GSM or VHF) communication mostly, with the transmission of dialling by telephone wire, also have and adopt power line or other circuit to transmit, but all have certain limitation:

1. adopt the apparatus cost of communication more expensive, the cost of use height, some ground square signal can not cover, and reliability is not as the wire communication mode.

2. adopt the point-to-point transmission mode of control point and monitored some direct-dial telephone dialing need be equipped with special modulator-demodulator, the line is busy easily and put through the low problem of rate in existence, the dialing time is long, communication cost also higher (needing sometimes to charge) by toll telephone, when monitored more, the transmitted data amount few time of counting out many and when widely distributed this problem particularly outstanding, and the transmission means of other circuit or equipment are too expensive, or are that technology is immature.

Summary of the invention:

In order to overcome radio communication cost height in the monitoring, the line is busy for problems such as blind area and phone dialing mode, dial the obstructed and high problem of expense, adopted frequency shift keying (FSK:FreguencyShift Keying) modulation system on the device of the present utility model, with of short message (SMS:ShortMessage Service) the form packing of monitoring data according to telecommunication specification, after fixed network message information telephone machine FSK modulation, send to the SMS service center of telecom operators earlier, transmit the monitored instruction of delivering to Surveillance center of Surveillance center by service centre again and also send to monitor terminal by the FSK modulation and by short message format by telephone wire.

Its communication mode that adopts is with the point-to-point communication mode difference of original dialing: the telephone number that the utility model needn't directly be put through Surveillance center earlier could transmit data then, but the special service number of telecom operators' SMS service center is dialled by elder generation, data are sent on telecom operators' short message service server by short message format get final product, short message service server stores processor short message data, and transmit short message data to the Surveillance center phone of appointment.Otherwise the instruction of Surveillance center also is to transmit by SMS service center.Effect:

Adopt the utility model device, the signal that can overcome the wireless communication transmissions mode does not cover, cost and usage charges height, the defective of poor stability; The line is busy when also having solved simultaneously the point-to-point transmission mode of dial-in direct, and extendibility is poor, the problem that usage charges are high.Adopt the utility model can accomplish short message format unified (can realize fixing, move and the Internet between exchange of short messages), transmission cost is cheap, and speed is fast, and is reliable and stable, the data of sending can not lost, and are particularly suitable for control point remote monitoring monitoring needs more for a long time.
