Problems solved by technology

[0002] The host speed signal is generated by a magnetoelectric speed sensor. After the host monitoring system fails or is repaired, the monitoring system needs to be tested and debugged. When the host speed signal needs to be detected and debugged, the host must be started, which consumes energy. It is easy to cause damage to the host, and at the same time increases labor intensity and difficulty in debugging

Abstract

The invention relates to a vessel host rotating speed signal generator. The generator comprises: a power supply circuit, a square wave generation circuit with an adjustable frequency, a fundamental wave selection circuit, a compensating circuit, an output circuit and a display circuit. The power supply circuit comprises: an AC / DC switch power supply, a storage battery and a change over switch. The square wave generation circuit with the adjustable frequency comprises: 555 and a potentiometer. An output terminal is connected with an input terminal of the fundamental wave selection circuit. The fundamental wave selection circuit comprises an inductor and a variable capacitor. The output terminal is connected with the input terminal of the compensating circuit. The compensating circuit is formed by the inductor and the capacitor. The output circuit, which is formed by the potentiometer and an isolation transformer, is connected with the output terminal of the compensating circuit. A 1KHZ-6KHZ sine wave host rotating speed signal is output by a secondary of the isolation transformer. The display circuit comprises: a frequency meter, a voltmeter and a revolution meter. The frequency meter and the revolution meter are connected with the output terminal of the fundamental wave selection circuit. The voltmeter is connected with an adjusting terminal of the output adjusting potentiometer.

Description

technical field [0001] The invention belongs to the technical field of electrical and electronic instruments, in particular to a signal generator capable of simulating the rotational speed signal of a ship's main engine to detect and debug a main engine monitoring system without starting the main engine. Background technique [0002] The host speed signal is generated by a magnetoelectric speed sensor. After the host monitoring system fails or is repaired, the monitoring system needs to be tested and debugged. When the host speed signal needs to be detected and debugged, the host must be started, which consumes energy. It is easy to cause damage to the host, and simultaneously increases labor intensity and difficulty in debugging. Contents of the invention [0003] The purpose of the present invention is to provide a generator for the speed signal of the main engine of a ship, which can simulate the rotational speed signal of the main engine to detect and debug the main en...
