Abstract

The utility model discloses a remote video-audio frequency multifunctional alarm system comprising an STC 89C52cpu, wherein an input end of the STC 89C52cpu is connected with a remote control receiving circuit, a wired alarm input end, an off-hook circuit, an HT9170 double audio frequency decoding circuit, an RS232 communication circuit and a power state monitoring circuit; and at the same time, an output end of the STC 89C52cpu is respectively connected with a fault display circuit, an alarm display circuit, an alarm audio frequency output circuit and an HT9200 double audio frequency transmission circuit. The remote video-audio frequency multifunctional alarm system provided by the utility model has the advantages of realizing real time transmission of alarm messages and real time browsing of monitoring pictures, and combining some traditional functions, such as anti-theft alarm, video monitoring and the like organically so as to make the required monitored objects audible, visible and controllable, thus solving the problem that an alarm function is disabled when power off.

Description

The long-range audio frequency Multi-function Warning System of looking

Technical field

The utility model relates to the antitheft field, especially a kind of long-range audio frequency Multi-function Warning System of looking.

Background technology

Mainly there is following problem in alarm in the market:

1, its vision signal, alerting signal all are through Network Transmission; We know that there is certain instability in Network Transmission, for example network delay, network congestion, broken string etc.; These problems are particularly outstanding in home network, and this makes the warning function reliability of alarm not ensure;

2, because video frequency processing chip power consumption is bigger, adds external camera and want power consumption, so can not use standby power supply, in case have a power failure, all functions of alarm just will lose efficacy.

The utility model content

The utility model technical assignment is to not enough in the above-mentioned technology, and a kind of long-range audio frequency Multi-function Warning System of looking is provided.

The utility model technical solution technical scheme that problem adopts is: the long-range audio frequency Multi-function Warning System of looking; Comprise STC 89C52cpu; The input end of said STC 89C52cpu and remote-control receiving circuit, wired alarming input end, circuit for answering, HT9170 double-tone decoding circuit, RS232 communicating circuit and power supply status supervisory circuit frequently link to each other, and the output terminal of said STC89C52cpu of while is connected with fault, alarm indication circuit, alert audio output circuit and HT9200 double-tone respectively and takes place frequently and send circuit.

Said STC 89C52cpu also links to each other with the MPG440 video processor through RS232 communicating circuit, power supply switch circuit, is connected with video acquisition module, audio collection module, Ethernet module, SDRAM, NAND Flash, RS485 cradle head control and debugging interface on this MPG440 video processor respectively.

Being connected with Isd1110 sound circuit and HT9200 double-tone on the said circuit for answering takes place frequently and send circuit.

Said power supply switch circuit is connected with power supply, standby power supply simultaneously.

The beneficial effect that the utility model can bring is:

(1) realize the real-time transmission of warning message and the displaying live view of monitored picture, functions such as traditional burglar alarm, video monitoring combined, make we to the monitored object of needs can listen, visual, controlled;

When (2) having solved power failure, the problem that detectors lost efficacy;

(3) can carry out Intelligent Measurement to the fault of telephone line.

Embodiment

Below in conjunction with accompanying drawing, the utility model is done following detailed description:

Shown in accompanying drawing 1; The long-range audio frequency Multi-function Warning System of looking; Comprise STC 89C52cpu; The input end of said STC89C52cpu and remote-control receiving circuit, wired alarming input end, circuit for answering, HT9170 double-tone decoding circuit, RS232 communicating circuit and power supply status supervisory circuit frequently link to each other, and the output terminal of said STC89C52cpu of while is connected with fault, alert audio output circuit, HT9200 double-tone respectively and takes place frequently and send circuit and alarm indication circuit.LED display window during warning on the panel can demonstrate the warning orientation, and the alert audio output circuit can be exported the high-decibel chimes of doom, reaches alarm function.If during faults such as telephone wire appearance broken string, short circuit, the trouble light on the alarm will light, prompting customer inspection circuit.If telephone line occupied (conversing) when reporting to the police generation, alarm can be hung up ongoing conversation immediately, dials the phone of receiving a crime report then, can realize the priority function of reporting to the police.

Said STC 89C52cpu also links to each other with the MPG440 video processor through RS232 communicating circuit, power supply switch circuit, is connected with video acquisition module, audio collection module, internet Network Interface Module, SDRAM, NAND Flash, RS485 cradle head control and debugging interface on this MPG440 video processor respectively.

Remote-control receiving circuit receives that telepilot sends comprises address and director data string; Deliver to STC89C52CPU and carry out decoding processing; Obtain the address code and the order code of telepilot; And it is do comparison, if consistent then make the control of phase factor according to instruction with the address code that is stored in the setting among the EEPROM in the sheet.Telepilot has three buttons, respectively correspondence set up defences, withdraw a garrison, three kinds of functions of emergency alarm.

Entering is set up defences behind the state, and STC 89C52CPU can detect the state of scanning wired alarming input end in real time, and from signals such as the infrared radio probe of remote-control receiving circuit, wireless door magnetic, telepilots.If detect effective alerting signal, the circuit for answering action realizes the simulation off-hook, and the telephone number of receiving a crime report that CPU will be provided with in advance takes place frequently through the HT9200 double-tone and send circuit to send.Behind the closing of the circuit, will hear the voice of prerecording in the Isd1110 sound circuit in the phone of receiving a crime report, inform the personnel's field condition of receiving a crime report.The personnel of receiving a crime report can realize monitoring functions such as on-the-spot sound, cancellation warning through telephone key-press Long-distance Control warning system.The push button signalling of Long-distance Control is by the decoding circuit decoding frequently of HT91 7 double-tones, delivers to STC89C52CPU after converting digital signal to, and STC 89C52CPU makes control corresponding.

The Internet video part is a core with dedicated video process chip (MPG440), and MPG440 is that low-cost, highly integrated high-performance vision signal is handled development platform, is primarily aimed at Internet video and optimizes, and makes Network Video Transmission smooth more.After video and sound signal process front-end video collection module and audio collection module are carried out the A/D conversion, deliver to video frequency processing chip and handle, formation can be connected in the network through the internet Network Interface Module in the data stream of transmission through network.

Said power supply switch circuit is connected with power supply, standby power supply simultaneously, with the influence of anti-power failure to antitheft, guarantees the continuity of antitheft work.

The utility model is guaranteeing the high performance while of antitheft, and production cost is low again, promotes easily.
