Example Embodiment

[0011] A microwave sensor module, a switch circuit, and an alarm module are installed on the warning sign 1. The microwave sensor module includes a battery BT, a microwave sensor H, and a switch K. The microwave sensor H is connected to the battery BT through the switch K, and the output terminal is connected to the base of the transistor Q. The emitter of the transistor Q is grounded, the collector is connected to the battery BT through the relay J and the switch K in turn, the movable contact 2 of the relay J is connected to the battery BT through the switch K, the normally closed contact 1 is empty, and the normally open contact 3 is connected. The input terminal of the alarm module. The alarm module includes resistor R1-3, capacitor C1-3, 555 timer U1, voice module U2, speaker L, and flash tube VD. Pin 1 of 555 timer U1 is grounded, and pins 2 and 6 are connected through capacitors. C1 is grounded and connected to the normally open contact 3 of relay J through the voltage d...

Abstract

The invention provides an acoustic-optical electronic warning board which comprises a warning board body with warning signs. The acoustic-optical electronic warning board is characterized in that a microwave induction module, a switch circuit and an alarming module are mounted on the warning board body, wherein the microwave induction module comprises a battery BT, a microwave sensor H and a switch K; the microwave sensor H is connected with the battery BT through the switch K; the output end of the microwave sensor H is connected with the alarming module through the switch circuit. On the basis of existing sign warning, the acoustic-optical electronic warning board is additionally endowed with an acoustic-optical alarming function, and is complete in function and ideal in warning effect; moreover, the phenomena of being neglected are reduced, and particularly the phenomena of being neglected at night or in poor light are reduced; the working performance is high.

Description

technical field [0001] The invention provides an acousto-optic electronic warning sign, 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 warning sign which can overcome the above defects, has a reasonable structure, complete functions and ideal warning effect. Its technical solution is: [0004] It includes a warning sign with warning slogans, and is characterized in that: a microwave induction module, a switch circuit and an alarm module are installed on the warning sign, wherein the microwave induction module includes a battery BT, a microwave sensor H and a switch K, wherein the microwave sensor H passes through the switch K is connected to the ba...
