Abstract
In order to solve the problems in the prior art that, the terminals of existing alarm systems are dependent of dual-audio telephone lines to complete the information transmission, thus being lower in reliability and higher in operating cost; and existing GPRS transmission systems are higher in replacement cost, the utility model provides the GPRS conversion equipment of an alarm system, which comprises a voltage detector, a dual-audio decoder, a GPRS converter and a GPRS transmitter. The terminal of the alarm system is sequentially connected with the dual-audio decoder, the GPRS converter and the GPRS transmitter through a telephone communication line. The voltage detector and the telephone communication line are connected with the terminal of the alarm system. The terminal of the alarm system is connected with the double-audio decoder through a conversion circuit. According to the technical scheme of the utility model, in normal conditions, the equipment is in information interaction with a control system through a telephone communication line. When the equipment is controlled manually or the telephone communication line breaks down, the equipment is in information interaction with the control system based on the GPRS. Therefore, the reliability of the alarm system is improved, and the cost of the alarm system is lower.
Description
Technical field
The utility model relates to a kind of warning system information transmission technology, specially refers to a kind of warning system GPRS conversion equipment.
Background technology
Prior art warning system terminal conventionally realizes warning system networking by telephone network line and connects, and by the transmission of double-audio signal information.Because telephone network line belongs to wired network, in the time there is the situation such as disaster or artificial theft, be easy to cause communication stage casing, cause warning message not transmit in time.In addition, because the speed of dual tone phone line transmission is slower, easily leak and pass or postpone situation about uploading in the cloth peak period generation information of withdrawing a garrison, thereby produce trouble and the cost that alert service company phone is checked.At present, occurred the warning system terminal based on general packet radio service technology GPRS, mounted warning system is as upgraded to GPRS transmission system.Can only, by changing warning system end host, certainly will increase cost.Obviously, prior art warning system terminal exists dependence dual tone phone line and carries out communication, and reliability is lower and operation cost is higher; Change GPRS transmission system, the problem such as cost is higher.
Summary of the invention
For the dependence dual tone phone line that solves the existence of prior art warning system terminal carries out communication, reliability is lower and operation cost is higher; Change GPRS transmission system, the problem such as cost is higher, the utility model proposes a kind of warning system GPRS conversion equipment.The utility model warning system GPRS conversion equipment, comprise warning system terminal, control system and telephone communication circuit, warning system terminal is connected with control system by telephone communication circuit, it is characterized in that, described GPRS conversion equipment comprises voltage-level detector, dual-audio demoder, GPRS converter and GPRS transmitter, warning system terminal is by telephone communication circuit and dual-audio demoder, GPRS converter and GPRS transmitter are linked in sequence, voltage-level detector is connected with telephone communication circuit and warning system terminal, warning system terminal is connected with dual-audio demoder by change-over circuit.
The useful technique effect of the utility model warning system GPRS conversion equipment is under normal conditions, keep information interaction by telephone communication circuit and control system, in the time that manual control or telephone communication circuit break down, keep information interaction by GPRS and control system, improved the reliability of warning system, and cost is lower.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model warning system GPRS conversion equipment.
Below in conjunction with the drawings and specific embodiments, the utility model warning system GPRS conversion equipment is further described.
Embodiment
Accompanying drawing 1 is the structural representation of the utility model warning system GPRS conversion equipment, as seen from the figure, the utility model warning system GPRS conversion equipment, comprise warning system terminal, control system and telephone communication circuit, warning system terminal is connected with control system by telephone communication circuit, it is characterized in that, described GPRS conversion equipment comprises voltage-level detector, dual-audio demoder, GPRS converter and GPRS transmitter, warning system terminal is by telephone communication circuit and dual-audio demoder, GPRS converter and GPRS transmitter are linked in sequence, voltage-level detector is connected with telephone communication circuit and warning system terminal, warning system terminal is connected with dual-audio demoder by change-over circuit.The utility model warning system GPRS conversion equipment, voltage-level detector is connected with telephone communication circuit and warning system terminal, voltage-level detector detects the outside line voltage of telephone communication circuit, when voltage is normal, also under normal conditions, warning system terminal keeps information interaction by telephone communication circuit and control system.In the time that voltage-level detector detects the outside line electric voltage exception of telephone communication circuit, show that fault has appearred in telephone communication circuit, voltage-level detector provides internal simulation telephone wire power supply to warning system terminal, simultaneously, by the information interaction connection of warning system terminal to dual-audio demoder (as shown in dotted line in accompanying drawing 1), dual-audio demoder is decoded to the double-audio signal of warning system terminal and is passed to GPRS converter, GPRS converter changes and passes to GPRS transmitter to signal, GPRS transmitter sends information accordingly.The GPRS receiver that is arranged on control system will receive this information (as shown in dotted line in accompanying drawing 1), realizes the information interaction of control system and warning system terminal.Certainly, also can pass through manual control, by the information interaction connection of warning system terminal to dual-audio demoder (as shown in dotted line in accompanying drawing 1), control system and warning system terminal realize information interaction by GPRS.Obviously, control system, completely can be according to foregoing description contrary operation to the information interaction of warning system terminal, can realize control system based on GPRS and the information interaction of warning system terminal
Obviously, the useful technique effect of the utility model warning system GPRS conversion equipment is under normal conditions, keep information interaction by telephone communication circuit and control system, in the time that manual control or telephone communication circuit break down, keep information interaction by GPRS and control system, improved the reliability of warning system, and cost is lower.
