Abstract
The utility model relates to a flash alarm system which mainly comprises a power supply board, a main board and a display board, and is characterized in that the upper side of the main board is connected with the power supply board through a single row of pins, and the right side thereof is connected with the double rows of pin blocks of the display board through double rows of curved pins, is clamped into a front cover together with the main board, the power supply board and the display board, and then is clamped into a rear end cover; a signal input signal and a communication output signal contact and are connected with a golden finger on the main board through a terminal shrapnel of the rear end cover; and a power supply input signal, an alarm output signal and an external button input signal contact and are connected with a golden finger on the power supply board through the terminal shrapnel of the rear end cover. The flash alarm system has the advantages of simple structure and quick installation, can be configured on line, and adopts a switching power supply; and relay isolation is adopted for input and output, so that the overall anti-interference of the flash alarm system is greatly improved.
Description
Technical field
The utility model relates to industrial automation instrument, refers more particularly to the flash alarm of all kinds of automated systems.
Background technology
Present flash alarm comprises: power panel, mainboard, tablet, output board etc., and its shortcoming is a complex structure, can not freely dispose, versatility is poor, the Installation and Debugging difficulty, poor anti-interference etc., narrow in the automated system the inside.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned defective, to provide a kind of simple in structure, and Installation and Debugging are convenient, can be the prime power devices, can freely dispose input and output, and is general strong, anti-interference strong flash alarm.
Its technical scheme of dealing with problems is as follows: a kind of flash alarm mainly comprises: power panel, mainboard, display board; It is characterized in that: the mainboard upside links to each other with power panel by single pin, the right side by double looper and the double needle stand of display board to company, mainboard, power panel, display board snaps in front cover together, snap in rear end cap then, the signal input signal contacts with golden finger on the mainboard by rear end cap terminal shell fragment with the communication output signal and links to each other, the power supply input, alarm output signal contacts with golden finger on the power panel by rear end cap terminal shell fragment with external button input and links to each other, button input setting value on the display board, represent respective value by the light-emitting block light on and off, CPU is by reading the input storage 74HC244 of institute, obtain each way switch amount input state, compare with the corresponding effective status of setting, effective input signal, send corresponding light-emitting block flash of light, alarm relay output action, output contact closure, according to setting sound equipment output, drive inner hummer and send the sound, can pass through the master-slave response communication modes, read various data by host computer.
The utility model advantage is simple in structure, and it is convenient to install, can Configuration Online, adopt Switching Power Supply, and input, output adopt relay to isolate, and the whole anti-interference of flash alarm improves greatly, more can adapt to large, medium and small all kinds of automated system.
