Abstract

The invention provides a ship warning main circuit board and a ship warning system. The main circuit board is provided with multiple paths of control circuits, wherein each path of control circuit comprises a monitoring input terminal, a voice control circuit and an indication lamp output circuit, the voice control circuit and the indication lamp output circuit both are electrically connected withthe monitoring circuit terminal, the voice control circuit comprises a noise reduction input terminal, a relay switch and a voice output terminal, the noise reduction input terminal is electrically connected with an electromagnetic coil terminal of the relay switch by a first diode, the monitoring input terminal is electrically connected with a normally-closed first terminal of the relay switch by a second diode, the voice output terminal is electrically connected with a normally-closed second terminal of the relay switch, the indication lamp output circuit comprises a fourth diode and a first indication lamp output terminal, a first end of the fourth diode is electrically connected with the monitoring input end, and a second end of the fourth diode is electrically connected with the first indication lamp output terminal. The system is applied to the main circuit board. The main circuit board is simple in structure and is stable to work.

Description

technical field [0001] The invention relates to the technical field of ship alarm circuits, in particular to a ship alarm main circuit board, and also to a ship alarm system using the ship alarm main circuit board. Background technique [0002] At present, there are many types of marine alarm system products, from the early complex alarm control circuit composed of multiple relay control circuits, to the single-chip microcomputer module, and now to the development and wide application of the programmable controller module. Since the technical requirements of the complete set of products are relatively high and the manufacturing process is complicated, the price of the products produced is also relatively expensive. The application of these products is not very practical for some systems with relatively simple purposes and equipment with a small number of alarm points. Therefore, in order to reduce the cost and simplify the complexity, it is necessary to further improve the ...
