Abstract
The utility model discloses a high-voltage warning device. The high-voltage warning device comprises an infrared pyroelectric sensor, a trigger control circuit, a voice sound production circuit and a loudspeaker. The infrared pyroelectric sensor is connected with the trigger control circuit, the voice sound production circuit and the loudspeaker successively. According to the utility model, advantages of security, reliability, high sensitivity, good anti-interference ability and large control range are realized, and the voice sound production circuit is used for voice warning, so the high-voltage warning device can be used in places, such as transformer substations, high-voltage wires, high-voltage cabinets, etc., to remind people to pay attention to their safety and avoid danger.
Description
Technical field
The utility model belongs to the electronic alarm technique field, be specifically related to a kind of Keep Clear-High Voltage the warning phonetic alarm device.
Background technology
The places such as transformer station, hi-line, high-voltage board should it can work the mischief to human body with high voltage, even can endanger people's life security, so these zones are forbidden zones; At present just set up warning board to carry out playing the effect of caution in these hazardous locations, but often can not stop incomer unintentionally or child's fond of play step, therefore can not be only by setting up the effect of warning board to warn and to accuse.
The utility model content
The utility model purpose: the purpose of this utility model is in order to solve the deficiencies in the prior art, and a kind of Keep Clear-High Voltage warning phonetic alarm device is provided.
Technical scheme: a kind of high pressure warning device described in the utility model, comprise pyroelectric infrared sensor, trigger control circuit, speech utterance circuit and loudspeaker, described pyroelectric infrared sensor are connected with loudspeaker with trigger control circuit, speech utterance circuit successively.
The single-shot trigger circuit that described trigger control circuit is comprised of 555 integrated chips and resistance, electric capacity.
The voice warning circuit that described speech utterance circuit is comprised of LJL676.
Beneficial effect: the utility model has the advantages that safe and reliablely, highly sensitive, antijamming capability is strong, and range of control is large, and adopt the speech utterance circuit to carry out voice warning, can be applicable to the places such as transformer station, hi-line, high-voltage board, remind people to note personal safety, avoid causing danger.
Description of drawings
Fig. 1 is the utility model circuit structure block diagram.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
A kind of high pressure warning device as shown in Figure 1 comprises pyroelectric infrared sensor, trigger control circuit, and speech utterance circuit and loudspeaker, pyroelectric infrared sensor are connected with loudspeaker with trigger control circuit, speech utterance circuit successively; The single-shot trigger circuit that formed by 555 integrated chips and resistance, electric capacity of trigger control circuit wherein, the voice warning circuit that the speech utterance circuit is comprised of LJL676.
