Abstract

The invention provides an acoustic-optical electronic alarm device, which comprises an infrared emission module, an infrared receiving and amplifying module, a driving module and an acoustic-optical alarm module, wherein the infrared emission module is connected with the driving module by the infrared receiving and amplifying module; and the driving module is connected with the acoustic-optical alarm module. The acoustic-optical electronic alarm device is characterized in that: the infrared emission module comprises a sensor H, a pulse emitter U1, a resistor R1 and an infrared ray emission tube VD, wherein an input end of the pulse emitter U1 is connected with the sensor H, and an output end of the pulse emitter U1 is connected with the infrared ray emission tube VD by the resistor R1; and the output end of the infrared ray emission tube VD is grounded. Based on the conventional slogan alarm, an acoustic-optical alarm function is added, so the acoustic-optical electronic alarm device has complete functions and ideal alarm effect, the condition that the device is neglected, particularly neglected at night or due to poor light is reduced, and the working performance is high.

Description

technical field [0001] The invention provides an acousto-optic electronic alarm device, which belongs to the technical field of warning signs for power systems. Background technique [0002] Most of the existing warning signs are signs with warning slogans, which have single functions and unsatisfactory warning effects, and cannot effectively warn. Contents of the invention [0003] The object of the present invention is to provide an acousto-optic electronic alarm device which can overcome the above defects, has a reasonable structure, complete functions and ideal alarm effect. Its technical solution is: [0004] It includes an infrared transmitting module, an infrared receiving amplifying module, a driving module and an acousto-optic alarm module, wherein the infrared transmitting module is connected to the driving module via the infrared receiving amplifying module, and the driving module is connected to the acousto-optic alarm module, and is characterized in that: the...
