Working principle

1. Working principle of digital microprocessor control module

Based on the closed-loop control logic of "signal acquisition algorithm operation execution control state feedback", precise control of the turbine/engine under all operating conditions is achieved: firstly, real-time operating data of the equipment is collected through various sensors (speed, temperature, pressure, etc.) and transmitted to the built-in microprocessor; The microprocessor analyzes and calculates the optimal control parameters (such as valve opening, fuel injection quantity, ignition timing, etc.) based on preset algorithms and control modes; Subsequently, a 0-10V DC analog signal is sent through the output interface to drive the actuator and achieve precise adjustment of speed or load; At the same time, the system continuously monitors the operating status of the equipment and its own working status. If abnormal parameters or component failures are detected, the alarm mechanism is immediately triggered and fault data is recorded to provide support for operation and maintenance.

2. Working principle of MicroNet TMR power case

As the power supply core of the MicroNet TMR system, it adopts the working logic of "redundant parallel+load sharing": two redundant power modules are simultaneously connected to the system, and during normal operation, they jointly bear the load and achieve power sharing, ensuring power supply efficiency; The built-in fault detection circuit in the chassis monitors the working status of two power modules in real time, such as output voltage, current, temperature, etc; When one of the modules fails, the detection circuit immediately sends a switching signal, and the faulty module quickly exits operation. The other normal module seamlessly takes over all loads and continues to supply power to the critical modules of the system, ensuring uninterrupted operation of the system; At the same time, the power module fault information can be fed back to the monitoring center through the system interface, reminding the staff to repair it in a timely manner.

Installation and commissioning precautions

To ensure the stable operation and safe operation of the product, installation and debugging must strictly follow the following requirements:

-Wiring specifications: ① Jumpers should be installed between the corresponding terminals (35&36, 38&39, etc.) for 4-20mA current input; ② Analog input/output (excluding power input and discrete input) is not isolated from other control inputs/outputs. If used in a common ground system, an additional isolator needs to be installed; ③ Strictly follow the on-site wiring diagram to verify the wiring, check whether the terminals are damaged, whether the screws are loose, and avoid poor contact.

-Mechanical linkage inspection: Check the linkage mechanism between the actuator and the fuel metering device/valve to ensure that there is no looseness or jamming; When the fuel valve is in the minimum fuel supply position, the actuator lever should be close to but not in the minimum stroke position to prevent engine overspeed from causing safety accidents.

-Sensor debugging: Check for visible damage to the speed sensor (especially the magnetic pickup), adjust the gap between the sensor and the gear to 0.25-1.25mm (closest point), and ensure that the gear runout does not exceed the pickup gap.

-Insulation testing: Measure the insulation resistance between all control terminals and the chassis. Except for terminals 2 and 24 (the resistance value depends on the power supply type), the insulation resistance of other terminals should be infinite; If the resistance value does not meet the standard, it is necessary to remove the terminal wiring one by one to troubleshoot the faulty circuit.

-Environmental requirements: The installation location should be away from dust, corrosive gases, and strong electromagnetic interference sources, ensuring good ventilation; Choose the appropriate installation posture based on the on-site environment to ensure the heat dissipation and protection performance of the equipment.
