Description
Technical field
The utility model relates to technical field of security and protection, in particular, relates to a kind of warning system based on GPRS (General Packet Radio Service, general packet radio service technology) transmission warning message.
Background technology
Along with socioeconomic continuous development; The single security protection measure or the facility of the firm door that people were accustomed to, lock, window bar can not satisfy current security protection requirement; Thereby according to current security protection requirement to people's life and property; International community's Safety Industry has been developed out synthesization, intelligentized network alarm centring system, and this system very the earth strengthens social safe precaution ability; Improve security service industry strength and public security cadres and police and command the usefulness of disposing great theft, public security, fire-fighting, first aid and all kinds of accidents, to greatest extent the safety of protection country and people's lives and properties.
Current; The transmission technology that the network alarm centring system is adopted when carrying out information transmission is transmitted based on telephone wire; Promptly protected the warning message of point (user side) to be transferred to warning command centre rapidly and accurately each, the guard personnel can in time be commanded dispose on-the-spot all kinds of accidents through telephone wire.
Because when adopting the warning message of each protection point of telephone wire transmission, the network alarm centring system can not be monitored each in real time and protected channel status a little, when transmission goes wrong, is difficult for being discovered by the network alarm centring system; And, the defective that itself exists during owing to the laying telephone wire, the maintainability when also causing through telephone line network transmission warning message is poor; Therefore, adopt telephone wire to carry out as easy as rolling off a log the going wrong of transmission of warning message, can't transmit warning message accurate and effective, timely thereby cause.
The utility model content
In view of this; The purpose of the utility model is to provide a kind of warning system based on GPRS transmission warning message; To overcome the transmission flaws that exists owing to telephone line network in the prior art, the problem that can't transmit warning message accurate and effective, timely that causes.
For realizing above-mentioned purpose, the utility model provides following technical scheme:
A kind of warning system based on general packet radio service technology GPRS transmission warning message comprises:
Gather warning message and said warning message carried out the ustomer premises access equipment of data processing;
Link to each other with said ustomer premises access equipment, the transmission equipment of the warning message after the reception data processing is arranged at GPRS transmission channel and the said warning message of internet transmission channel transfer in the said transmission equipment;
Link to each other with said transmission equipment, receive said warning message and carry out the platform of receiving a crime report of alarm.
Can know via above-mentioned technical scheme, compared with prior art, the utility model discloses a kind of warning system based on GPRS transmission warning message.When being connected in ustomer premises access equipment when detecting alert; Warning message to collecting is handled; And warning message is transferred to the platform of receiving a crime report through GPRS transmission channel and internet transmission passage; Fast based on transmission technology real-time online, the transfer rate of GPRS and have error correcting capability advantage; In the process of warning message transmission compared to telephone line network have more accurately, advantage more effectively and more timely, thereby guarantee that the guard personnel can handle warning message fast and accurately.
