Problems solved by technology

For example, motor vehicles such as public security, firefighting, and ambulance use a combination of rapid sirens and flashing lights as driving signals. The warning effect is obvious, but it will make people panic and even irritated. If it is commonly used in other occasions, it will be misleading; The high-pitched loudspeaker emits sound directly, and the warning range is large, but it will make people feel harsh and uncomfortable, causing noise pollution; the use of diffuse sound playback can form a uniform and soft sound field, but if the range is slightly larger, the power will be insufficient, and the warning sound will be blurred. clear

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the drawings and embodiments.

[0012] See figure 1 , The present invention is composed of a main controller module, an object entry and exit detection module, a brightness detection module, a sound warning module and a flash warning module. figure 2 It is a schematic circuit diagram of an embodiment of the present invention. Switches S1, C17, and R23 form a power-on reset circuit, and crystal oscillators Y1, C8, and C9 form a crystal oscillator circuit. Together with AT98S52, they form the minimum system of a single-chip microcomputer. M-JGDS-LZ5V-M12 laser through-beam sensors RE1~RE8 are respectively connected to the 8 pins of P0 port of AT89S52 single-chip microcomputer to form 8 segments of object entry detection. When a pin inputs an effective level, it indicates that the segment has Object enters. RE9~RE16 are also 8 M-JGDS-LZ5V-M12 laser through-beam sensors, which are used to detect whether...

Abstract

A construction field caution device uses an AT89S52 single-chip microcomputer as a master control device; an external expansion object enters a segment detection module; the object leaves the detection module, a brightness detection module and an acousto-optic caution module; connecting laser correlation sensors entered by detection objects of different segments with different pins of the single-chip microcomputer; when certain pin signal is valid, a sound caution module of the segment is started; when the object is detected to leave, the sound caution module is closed, thus ensuring the wholecaution scope of construction field caution devices to be large, ensuring each segment caution sound to be clear and soft, and preventing noise pollutions; in addition, red and yellow color flash cautions are employed, thus providing eye-catching cautions when the light is dark no matter in sunny and rainy and foggy weathers.

Description

Technical field [0001] The invention relates to an alarm device for a dangerous area in a construction site, in particular to a construction site alarm. Background technique [0002] For construction areas with potential accidents, preventing non-construction personnel from entering is the basic measure to reduce accidents, and early warning is the simplest and most economical means of accident prevention. It is very necessary to use sound and light on hearing and vision to alert relevant personnel of possible dangerous construction areas and prevent them from entering meaninglessly. It can effectively avoid and reduce construction site accidents. [0003] There are many types of traditional warning devices, which play a certain role in different occasions. For example, public security, fire fighting, ambulance and other motor vehicles use a combination of rapid sirens and flashing warning lights as driving signals. The warning effect is obvious, but it will make people panic and ...
