Abstract
A PLC-based (programmable logic controller-based) lift control system belongs to the field of facilities for public use. A motor for driving a lift to operate and a PLC console for controlling the motor to operate are mounted on the top storey of a building, and the PLC console can transmit the real-time operating condition signals of the lift to a wireless code receiver of a system monitoring center by means of a wireless code transmitter. The PLC-based lift control system has the advantages that: since a PLC control system is adopted to control the overall operation of the lift, the operation of a lift system can be safer and more stable and accurate, and at the same time, the lift system also can be monitored in real time.
Description
Technical fieldThe present invention relates to the elevator control gear based on PLC, belong to public use facility field.
Background technologyAlong with social progress, the city changes with each passing day, high-rise emerges in an endless stream, people enjoyment occupy a commanding position appreciate beautiful scenery joyful in, also have in the face of a realistic problem, that is exactly how to shuttle back and forth easily between skyscraper and ground, so elevator is sought and given birth to, nowadays, people are increasing to the dependence of elevator.Usually elevator comprises that eight large systems consist of, and are respectively: traction system, guidance system, car, door system, weight balancing system, electric drive system, electric control system, safety system; The common all spaces in a newspaper of elevator accident mainly are because the electric control system quality does not pass a test, and cause Frequent Accidents.
Summary of the invention
The purpose of this invention is to provide the more safe and reliable elevator control gear based on PLC of a kind of use.
For achieving the above object, the technology used in the present invention solution is: based on the elevator control gear of PLC, at the top layer of building the electrical motor that drives the elevator operation and the PLC control desk of controlling the electrical motor operation are installed, the PLC control desk can be sent to the real-time condition signal of elevator operation the wireless encoding receptor at system monitoring center by the wireless encoding producer.
Based on the elevator control gear of PLC, its beneficial effect is: adopt the overall operation of PLC control system control elevator, make the system of elevator move that safety and stability is accurate more, can also realize the Real Time Monitoring to elevator device simultaneously.
Description of drawings
Fig. 1 is the fundamental diagram based on the elevator control gear of PLC;
Fig. 2 is the local structural graph based on the elevator control gear of PLC.
Fig. 1, Fig. 2 Reference numeral are as follows: 1, elevator, 2, the wireless encoding producer, 3, the wireless encoding receptor, 4, monitoring and control centre, 5, the PLC control desk, 6, electrical motor.
The specific embodiment
Below in conjunction with Fig. 1, Fig. 2 the elevator control gear based on PLC is described as follows: at the top layer of building the electrical motor 6 that drives elevator 1 operation and the PLC control desk 5 of controlling the electrical motor operation are installed, PLC control desk 5 can be sent to the real-time condition signal of elevator 1 operation the wireless encoding receptor 3 at system monitoring center 4 by wireless encoding producer 2.
Employing PLC control system is controlled the operation of electrical motor 6 and is stopped, and electrical motor 6 drives the overall operation of elevators 1, and the PLC program design makes the system of elevator 1 move more safety and stability, can also realize the Real Time Monitoring to elevator device simultaneously.
