Intelligent integrated controller of generator set and control method thereof

Abstract

The invention relates to an intelligent integrated controller of a generator set and a control method of the intelligent integrated controller. The intelligent integrated controller of the generator set comprises an MCU, an I/O control circuit, a communication unit, a human-machine interaction unit, a storage unit and a power source unit. The I/O control circuit is connected to a sensor detection unit, an executing unit and a 32-bit I/O port capable of being redefined. The sensor detection unit comprises an oil pressure sensor, a diesel oil level sensor, a cooling water temperature sensor, an engine starter rotation speed sensor, a diesel engine rotation speed sensor, a three-channel current sensor, a three-channel mains voltage sensor, a three-channel generator voltage sensor and a generator rotation speed sensor. The executing unit comprises a generator voltage automatic adjustment executor, an engine starter, an emergency stop button, a fuel injection pump executor, a cooling liquid high water temperature switch, a low oil pressure switch, an external locking switch and a breaker closing and opening controller. By the adoption of the intelligent integrated controller of the generator set and the control method of the intelligent integrated controller, the labor cost can be reduced, and the reliability of products is greatly improved.

Description

Technical field [0001] The invention relates to an intelligent integrated controller for a generator set and a control method thereof. Background technique [0002] Diesel generator sets and gas generator sets (hereinafter referred to as generator sets) are widely used in various industries due to their light weight, simple structure and high power density. The generator sets sold on the market are composed of four parts: engine, generator, control System, peripheral support system. The engine provides power, the generator converts the power provided by the engine into electrical energy, the generator set works under the control of the control system, and the peripheral support system supports the work of the generator set. [0003] The control system of the generator set is very important in the work of the generator set. If the generator set is compared to a person, the generator set control system is equivalent to the human "brain". The power generation function of the generat...

Problems solved by technology

[0005] (1) In the production and manufacturing of generator sets, a large number of control connecting wires cause time-consuming, laborious, and material-intensive production of generator sets. The connected sensors on the traditional generator set controller have oil pressure sensors, high water temperature sensors, and three-phase Current transformers, three-phase voltage monitoring wires, battery voltage monitoring wires, fuel level sensors, these sensors must be connected to the controller through wires, due to the power limitation of traditional controller output digital quantities, external relays must be connected to expand the output power control The starting of the generator set and the speed of the generator set

These have greatly increased the number of devices and wires outside the controller, resulting in a large amount of man-hours and wire materials for the electrician to complete the manufacturing of the control system. From the perspective of the enterprise, on the one hand, it increases the material manufacturing cost of the generator set.

Another aspect leads to the fact that enterprises must use high-quality electricians to complete the wiring, which increases the requirements of workers, increases labor costs, increases product costs, and increases product production cycles.
