Abstract
The utility model discloses an infrared traffic precaution device, including a housing. An infrared precaution circuit is arranged in the housing. The infrared traffic precaution device is characterized in that the circuit includes a power supply management unit, an infrared detection unit, a control unit and a playback module, when a person is detected, the infrared detection unit emits a trigger signal, and after the control unit receives the trigger signal, the playback module is controlled to play the precaution information stored in advance. In the utility model, the system energy consumption is reduced, the usage time of a cell is prolonged, and built-in recording content can be preserved for 10 years at a power-off state.
Description
Technical field
The utility model relates to traffic safety facilities.
Background technology
Mostly existing traffic prewarning facility is passive indication or pattern identification. situation of difficult can appear discerning unavoidably in restricted occasions in the visual field such as flow of the people are intensive. and simple sound early warning continual early warning sound that sends when not needing early warning. promptly increase the energy consumption of system, aggravated the pollution of environmental noise again.
The utility model content
The utility model purpose provides a kind of infrared induction can record precaution device, can realize not having dead angle early warning information transmission, and the early warning information transmission changes the intelligent trigger form into by uninterrupted form, and for adapting to different use occasions, the built-in information content can be changed.
The utility model adopts following scheme to realize above-mentioned purpose: a kind of infrared traffic prewarning device, comprise shell, and be provided with an infrared early warning circuit in the shell; It is characterized in that; This circuit comprises a power supply management unit, an infrared detecting unit, control module and a playback module, and when having detected man-hour, this infrared detecting unit sends a trigger pip; After above-mentioned control module receives this trigger pip, control this playback module and play the information warning of storage in advance.
Preferably, said infrared early warning circuit also comprises a recording module, in order to store the information warning of typing in advance.
Preferably, said information warning is stored in the Flash storer.
Preferably, when playing information warning, light warning lamp.
Preferably, said power supply management unit is by civil power or powered battery.
Preferably, said cover top portion and trailing flank are equipped with fixed via.
Preferably, said fixed via is provided with corresponding plastic closure.
Description of drawings
Fig. 1 can record precaution device internal circuit configuration figure for the utility model infrared induction.
Fig. 2 can record the precaution device shell for the utility model infrared induction.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, below will do further explain to the utility model through specific embodiment and relevant drawings.
Please refer to Fig. 1 and Fig. 2, a kind of infrared induction can be recorded precaution device, it is characterized in that; Comprise shell, be provided with the infrared induction circuit in the shell, this circuit comprises infrared probe module, power supply management module, control module and record button; This power supply management module is by civil power or powered battery, and this infrared probe module is exported to control module with the signal that detects, and this control module judges whether to need to trigger early warning; When detecting the moving human body infrared signal in the regulation zone; This control module triggers the inner early warning information of prerecording, and lights warning lamp according to the setting pattern, after pressing record button; Control section triggers recording/playback module and gets into recording state; Convert the sound signal of microphone or circuit input into digital signal and deposit in the FLASH storer in recording/playback module, cover top portion and side are equipped with fixed via 1, and fixed via 1 is provided with corresponding plastic closure.
Adopt the signal of sound, in the scope that sound is passed on, do not have the dead angle, the early warning demand when the solution visual field is restricted as early warning. adopt human body infrared detecting as the early warning trigger pip; Realize that the people comes early warning, the people walks to mourn in silence, and has reduced system energy consumption; Increased the service time of battery,, added the recording module that adopts the Flash storer in order to adapt to various early warning demand; Realize sound-recording function, and built-in recording substance can be preserved 10 years at no power supply state.
Above-listed preferred embodiment; Purpose, technical scheme and advantage to the utility model have been carried out further explain, it should be understood that the above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
