Abstract
The utility model provides a center-to-front call-out system for monitor and alarm based on forest fire prevention. The center-to-front call-out system comprises a first-level monitor center, a second-level monitor center and a front monitor point which transmit signals through a local area network in sequence. The first-level monitor center and the second-level monitor center are internally provided with a monitor host respectively. The monitor hosts are connected with an audio input device and an audio output device. The front monitor point is internally provided with an encoder used for forest fire video monitor. The encoder is connected with a loudspeaker through a power amplifier and is directly connected with a pickup. A relay is arranged between the encoder and the power amplifier. With the adoption of the center-to-front call-out system for monitor and alarm based on forest fire prevention, bidirectional voice intercommunication and call-out between a center and a front can be achieved. The center-to-front call-out system for monitor and alarm based on forest fire prevention can be used for command of the front by the center or voice report from the front to the center. The monitor centers switches on and off the power amplifier through a remote relay, power consumption is lowered, and consumption of a battery is prevented from being overlarge.
Description
Technical field
The utility model relate to a kind of based on forest fire protection monitoring, alarming with center to the front end system of propagandaing directed to communicate.
Background technology
The forest fire protection monitoring, alarming warning system of prior art, transmission of information or pass on instruction not there is two-way voice talkback and to propaganda directed to communicate function by communication apparatus, this has limited in use ageing of forest fire protection monitoring, alarming warning system greatly.
Utility model content
For above deficiency, the utility model provide a kind of based on forest fire protection monitoring, alarming with center to the front end system of propagandaing directed to communicate.
The technical solution of the utility model: based on forest fire protection monitoring, alarming with center to the front end system of propagandaing directed to communicate, comprise one-level Surveillance center, secondary Surveillance center and front end control point, between above-mentioned three, pass through in turn local area network (LAN) transmission of signal, wherein in one-level Surveillance center, secondary Surveillance center, be provided with monitoring host computer, monitoring host computer is connected with audio input device, audio output apparatus respectively, in front end control point, be provided with forest fires video monitoring encoder, encoder is connected with loudspeaker by power amplifier on the one hand, is directly connected with pick-up on the one hand.
Between encoder and power amplifier, be provided with relay.
The beneficial effects of the utility model: adopt the utility model can realize the two-way voice talkback of center and front end and propaganda directed to communicate, can report the voice at center the commander of front end or front end for center; In Surveillance center, by Long-distance Control relay, power amplifier started and close, can save power consumption, avoiding causing battery consumption excessive.
