The status signals of automated diesel generator sets can be divided into the following categories according to their functions: start/stop signals, diesel engine operating condition signals, generator status signals and other related signals.

1. Start/stop signal

The start/stop signals of the automated diesel generator set mainly include: the main power supply is abnormal and other necessary signals for the start of the unit set by the user according to the specific purpose of the unit. These signals are sent to the controller in a certain logical combination. When its logic value is "1", the unit will start automatically and act according to the prescribed control flow; when its logic value is "0", the unit will automatically stop after a delay. The detection of abnormal power signals usually uses phase-failure protectors and voltage comparators, etc. For some controllers with a power detection device, the detection of the power signal is performed inside the controller, and no external detection device is required.

2. Working condition signal of diesel engine generator set

In addition to the working conditions of the diesel engine, the working conditions of the diesel engine that need to be tested also include: whether the start is successful, whether the diesel engine speed is normal, whether the pressure of the lubricating oil is abnormal, and whether the temperature of the diesel engine is too high or too low. In order to protect the diesel engine, when the start fails, the diesel engine is overspeed, the lubricating oil pressure is too low or the temperature of the diesel engine is too high, the diesel generator set will automatically stop and alarm, and the system will automatically lock. Without manual intervention (unlocking), the unit will not start automatically even after receiving a start signal. Such signals are usually detected by dedicated sensors, such as speed sensors, pressure sensors, and temperature sensors.

3. Generator status signal

In order to supply power to the load safely, it is necessary to detect the status signals of the generator, such as the voltage, current, frequency of the diesel generator, and the status of the automatic switching system (ATS). When the above power is out of tolerance, corresponding protective measures should be taken to avoid reducing the power supply quality of the generator or causing serious accidents to damage the diesel generator.

4. Other signals

In addition to the above signals, as an automatic control system, it also detects the battery's own voltage and charging voltage, fuel level, lubricating oil level, coolant temperature, and liquid level to ensure that the diesel generator set is always in normal The standby machine status meets the requirement that the unit can be started at any time. In addition, monitoring systems for automated diesel generator sets used in many neighborhoods such as post and telecommunications, national defense, and important public places generally use room environment signal detection.
