Problems solved by technology
Limited by technology, the efficiency of current solar cells is still relatively low, and at the same time the power consumption of power amplifiers and sound amplification equipment is relatively large, and in the prior art, power amplifiers and sound amplification equipment are always in a power-on state. Therefore, it will cause a shortage of power resources and even affect the normal operation of the forest fire monitoring system.
But in fact, the time for the monitoring personnel to call the forest rangers one-way every day is very short, or even none. This increase in power supply, that is, correspondingly increasing the area of solar panels and the capacity of batteries, etc., will undoubtedly increase investment, and the actual use efficiency of these investments will be very low, resulting in a serious waste of investment

Embodiment Construction
[0049] Aiming at the problems existing in the prior art, the present invention proposes a power supply control method in the forest fire monitoring system, adding a remote control output interface on the audio and video codec equipment, and connecting the equipment to be powered, usually referring to the power amplifier and A relay is connected in series between the sound amplification equipment and the power supply; the remote control output interface can output a low-voltage switch control signal, thereby controlling the relay to be turned on and off. In addition, a remote switch button is added on the software interface running on the system platform. The monitoring personnel can operate the button with the mouse. If the button is clicked, the control relay is turned on, and the button is clicked again to control the relay to be turned off.
[0050] Based on the above introduction, the specific implementation of the solution of the present invention includes: the system plat...

The invention discloses a forest fire monitoring system and a power supply control method for the same. The method comprises the following steps of: increasing a remote control output interface on far-end audio / video coding / decoding equipment, and connecting a relay in series between far-end power to-be-supplied equipment and a power supply; determining whether to supply power to the power to-be-supplied equipment through a system platform positioned in a monitoring center, if so, sending power supply start message to the audio / video coding / decoding equipment, and sending a control signal to the relay through the remote control output interface by the audio / video coding / decoding equipment to control the start of the relay; and determining whether to stop power supply through the system, if so, sending power supply stop message to the audio / video coding / decoding equipment, and sending a control signal to the relay through the remote control output interface by the audio / video coding / decoding equipment to control the shutdown of the relay. By using the scheme, the power consumption of the power to-be-supplied equipment such as a power amplifier, voice amplification equipment and the like can be reduced, and normal operation of the forest fire monitoring system can be ensured without increasing the investment.
Description
technical field [0001] The invention relates to forest fire monitoring technology, in particular to a power supply control method in a forest fire monitoring system and a forest fire monitoring system. Background technique [0002] In the existing forest fire monitoring system, the monitoring personnel can see the video about the remote situation in real time in the monitoring center, and can conduct real-time two-way intercom with the remote forest ranger. [0003] Among them, when the monitoring personnel need to conduct two-way intercom with the ranger, first, the conversation content that needs to be transmitted to the ranger is transmitted to the system platform (that is, the central computer) in the form of an audio signal through a microphone; The analog audio signal collected by the sound card is digitized according to a certain encoding method; after that, the digitized audio signal is transmitted to the remote audio and video codec device through the wide area netw...
