Abstract
The utility model relates to a safety signboard, in particular to an inductive safety signboard capable of reminding people to be attentive via inducting a human body. The inductive safety signboard comprises a casing, and a loudspeaker and an infrared inductive probe are arranged on a surface of the casing. A triode amplifying circuit and an integrated sounding circuit are arranged in an inner cavity of the casing. The infrared inductive probe is connected with a base electrode of a triode, the integrated sounding circuit is connected with a collector electrode of the triode, and the loudspeaker is a piezoelectric ceramics loudspeaker. The inductive safety signboard has the advantages of simple structure and obvious reminding effect. When people approach, a weak signal generated by the infrared inductive probe can trigger the integrated sounding circuit after being amplified by the triode, then the integrated sounding circuit can automatically display voice consolidated in advance to remind the approaching people, so that operators and juveniles can be effectively protected from approaching danger areas such as the area with high-voltage cable.
Description
[technical field]
The utility model relates to a kind of secure ID board, particularly a kind of induction type secure ID board that points out through human body sensing.
[background technology]
Existing secure ID board can only belong to passive caution from visually reminding producers, and is in particular cases absent minded etc. like producers, often do not see the secure ID board, and prompting caution effect is limited, and security incident might take place.
[utility model content]
The utility model technical matters to be solved is to provide a kind of induction type secure ID board, and it can be in producers' active alarm during near the hazardous location.
The technical scheme of the utility model is: induction type secure ID board; Comprise secure ID board housing; Said surface of shell is provided with loudspeaker and infrared induction probe; Said housing inner chamber is equipped with transistor amplifier and sound IC actuated, and said infrared induction probe is connected with said transistor base, and said sound IC actuated and said transistor collector is connected.When human body during near nameplate, the feeble signal that the infrared induction probe produces is amplified the back through triode and is triggered music integrated circuit, and music integrated circuit is play the voice that are cured in advance and carried out active and warn.
The advantage of the utility model is: simple in structure, the caution effect obvious, can prevent effectively that operating personnel and minor are near hazardous locations such as high-tension cables.
[description of drawings]
Combine embodiment that the utility model is done further to describe with reference to the accompanying drawings.
Fig. 1 is the schematic appearance of the utility model,
Fig. 2 is the circuit theory diagrams of the utility model.
[embodiment]
Referring to Fig. 1, induction type secure ID board comprises secure ID board housing, and an infrared induction probe 2 has been installed in the positive below of housing 1, and a loudspeaker 3 has been installed in the upper right side, and loudspeaker 3 adopts piezoelectric ceramic loudspeaker in the present embodiment.Transistor amplifier and sound IC actuated element all are placed on housing 1 inside.
Referring to Fig. 2, infrared induction probe 2 is connected with said transistor base, and sound IC actuated 4 are connected with said transistor collector, and 5 is the solar recharging assembly.
When human body during near nameplate; The feeble signal that infrared induction probe 2 produces triggers sound IC actuated 4 after triode amplifies; Sound IC actuated 4 get electric startup, the warning voice that solidify are in advance just played back through piezoelectric ceramic loudspeaker 3, thereby reach the initiatively purpose of warning.
The utility model is fit to outdoor long-term use.As need be in indoor use, cancellation solar recharging assembly 5, and power supply is designed to removable battery 6 gets final product.
Although illustrated and described the embodiment of the utility model; For those of ordinary skill in the art; Be appreciated that under the situation of principle that does not break away from the utility model and spirit and can carry out multiple variation, modification, replacement and modification to these embodiment, the scope of the utility model is limited accompanying claims and equivalent thereof.
Claims (2)
