[0037] Examples of ship alarm system:
[0038] See Figure 4 The ship alarm system of the present invention includes a ship alarm main circuit board 20, a first monitoring panel 30, a second monitoring panel 40, and a sensor monitoring circuit group 50. The ship alarm main circuit board 20 is connected to the first monitoring panel 30 and the second monitoring The panel 40 and the sensor monitoring circuit group 50 are electrically connected.

[0041] The sensor monitoring circuit group 50 is provided with the same number of sensor monitoring circuits 501 as the control circuits 1, and each sensor monitoring circuit 501 is electrically connected to a corresponding control circuit 1 respectively. Each control circuit 1 is electrically connected to a sensor monitoring circuit 501 in the sensor monitoring circuit group 50 through the monitoring input terminal 2. The sensor monitoring circuit 501 can set the sensor circuit according to the alarm type that needs to be detected. For example, the alarm type can be a ship watertight door hatch alarm or a generator alarm. The sensor monitoring circuit 501 can use the existing known sensor monitoring circuit, which will not be repeated here. In the present invention, the sensor monitoring circuit 501 is used to generate an alarm signal for prompting on the control panel.
[0042] When the ship alarm system of the present invention is working, when any sensor monitoring circuit 501 in the sensor monitoring circuit group 50 generates an alarm signal, the voltage signal is transmitted to the first monitoring panel through the fourth diode D4 and the fifth diode D5 The first indicator light group 301 of 30 and the second indicator light group 401 of the second monitoring panel 40 make the indicator light emit light.

[0044] It can be seen from the above that the ship alarm main circuit board of the ship alarm system of the present invention can monitor and control multiple monitoring points at the same time by setting multiple control circuits. In addition, the ship alarm main circuit board of the present invention improves the complex circuit of the traditional single control of the relay. After adding the unidirectional characteristic of the diode, the circuit structure is simple and clear, which reduces the area and increases the tightness of the circuit and improves the contact of the relay. The impact of competition and the reverse voltage generated when the relay breaks on the circuit makes the circuit operation more accurate and stable. In addition, the control circuits all adopt the same circuit structure, making the product simpler, thereby reducing the manufacturing cost.
