Description

[0001] The present invention relates to an NMEA2000 elevator control panel and a control system thereof,

The present invention integrates measurement signals of sensors for checking the environment of the elevator and the environment of the elevator installed in the NMEA2000 elevator control panel and its control system and provides the provided information to the elevator control panel and provides the provided information through various communication interfaces, And a control system for controlling the elevator control panel capable of checking and controlling the state of the elevator even if the user is located at a remote location through the communication network.

The elevator industry is a machine that requires advanced technology that combines mechanical, electrical and electronic technologies.

Since it is a wine-intensive industry, it has various uses and types, and it needs continuous inspection and maintenance, it is an integrated industry that needs transportation machine fusion parts technology which is important for continuous service management after installation.

In Korea, the elevator, which was only 30,000 units by 1990, required elevators to be installed on 6th or higher floors, and the number of new high-rise buildings increased ten times in 15 years. The elevator type was also increased in size, .

For the safety of the elevator, the safety standards for the products assembled or processed for the elevator parts and the elevator are suitably tested by the Korea Elevator Safety Management Center and the Korea Industrial Technology Examination Center. ㅇ Inspection facilities o Technical ability and manufacturing system are evaluated The product is certified for safety. The safety inspection and maintenance of the elevator does not directly correspond to the product liability law because it does not correspond to the product as a service. If an accident occurs due to an elevator, if it develops into a product liability case, the manufacturer must prove that there have been no defects in the delivery, so that the manufacturer must carry out a thorough inspection at the stage of manufacturing shipment and verify it. It is getting higher. In addition, a system was needed to check the status of the elevator in real time, notify when an abnormality was detected, and control the elevator.

A conventional technique designed to meet such a need has been disclosed in Korean Patent Publication No. 10-2007-0012457.

Such conventional technology includes an elevator control unit for controlling the operation of the elevator car and an electronic safety controller for detecting an abnormality of the elevator and generating a command signal for shifting the elevator to a safe state, And when the abnormality of the electronic safety controller itself is detected, the closest layer stop command for stopping the car in the closest layer is outputted to the elevator control unit, and from the output of the closest layer stop command, When the set time has elapsed, an emergency stop command for emergency stopping the car is output to the elevator control unit.

However, in the related art, since the types of the measurement signals input from the sensors are different from each other, they must communicate with each other through respective communication modules, so that it is difficult to perform integrated operation. Then, in the data transmission for monitoring and reception of control signals, It is difficult to do so.

In addition, it is difficult to respond to an abnormality faster when an abnormality occurs due to not informing the user of the abnormality, and it is difficult to cope with other situations because it is possible to detect only the malfunction of the elevator car.
