Helmet type camera for mine

Abstract

The invention discloses a helmet type camera for mine, which comprises a host machine, a camera head and a camera head card, wherein the host machine receives a video signal and a sound signal which are outputted by the camera head, compresses the signals, stores the signals, and transmits the signals to a distant remote transceiver or a computer. The helmet type camera for mine is characterized by further comprising a remote controller; the host machine comprises a power managing module, an infrared receiving module, a video module, a sound module, a wireless transmitting module, a memorizer and a central processing unit; the remote controller is connected with the infrared receiving module through infrared; the remote controller outputs a password and a control order to the infrared receiving module; the infrared receiving module receives the password and the control order which are outputted by the remote controller, and outputs a control signal to the power managing module; and the power managing module receives the control signal outputted by the infrared receiving module, and performs the powering on, the powering off and the powering on at preset time.

Description

technical field [0001] The invention relates to a video recording device, in particular to a helmet-type video recording device for mining. Background technique [0002] Due to the complexity and variability of coal mine working conditions and working environment, it is necessary to collect audio and video data during the underground production process of coal mine. Explosion-proof camera device, the position of the camera device cannot be adjusted arbitrarily, and it cannot be moved with the workers to monitor multiple important sites; the existing camera in the coal mine is operable underground, and the underground operator can switch the machine on or off or delete the camera content at will, interfering with the camera process And camera data, which is unfavorable for on-site evidence collection and supervision of coal miners. [0003] In addition, because coal mine disaster accidents occur from time to time, after the accident, the communication between the rescue site...

Problems solved by technology

[0002] Due to the complexity and variability of coal mine working conditions and working environment, it is necessary to collect audio and video data during the underground production process of coal mine. Explosion-proof camera device, the position of the camera device cannot be adjusted at will, and it cannot move with the workers to monitor multiple important sites; the existing camera in the coal mine is operable underground, and the underground operator can switch the machine on or off or delete the camera content at will, interfering with the camera process And camera data, which is not good for on-site evidence collection and supervision of coal miners

[0003] In addition, because coal mine disaster accidents occur from time to time, after the accident, establishing the communication between the rescue site and the rescue headquarters as soon as possible, timely and accurately understanding the accident site and checking the danger is the key to analyze the accident and make the correct decision Basic, the video recorder used for audio and video data collection in the process of emergency rescue and investigation and evidence collection needs to be operated by hand during the whole process, which brings great inconvenience to users
