Elevator maintenance system

Abstract

The invention discloses an elevator maintenance system. The system comprises a portable part, maintenance control equipment, a short-distance card reader and a controller, wherein the portable part isprovided with identity information and operation information; the maintenance control equipment and the short-distance card reader are arranged in a functional area; the functional area is an area where entry of non-elevator professionals is forbidden; the maintenance control equipment and the short-distance card reader are both in communication with the controller; when the portable part entersa set position in the functional area, the short-distance card reader in the functional area can read the identity information and the operation information of the portable part and send the identityinformation and the operation information to the controller; and the controller configures permitted and forbidden operation items of the maintenance control equipment in the functional area accordingto the received identity information and operation information of the portable part, so that an elevator operates to enter a functional area protection mode. The elevator maintenance system is low incost and can avoid a risk possibly caused by the situation that someone accidentally enters the functional area to operate the maintenance control equipment.

Description

technical field [0001] The invention relates to an elevator, in particular to an elevator maintenance system. Background technique [0002] The current elevator protection function mainly considers the safety of passengers and elevator equipment, and less consideration is given to the safety of operators, and cannot monitor the existence and behavior of operators. [0003] During the commissioning and maintenance of the elevator, according to the work requirements, the operators may appear in various areas such as the machine room, car roof, inside the car, pit and floor door. Taking entering the car roof as an example, the standard operation steps are as follows: [0004] 1) If the machine room or the door of the top floor controls equipment accessories, operate the inspection device to put the elevator into the inspection state, at this time the elevator does not respond to the calling instructions of the landing and the car; [0005] 2) Make the elevator run for inspect...

Problems solved by technology

[0007]4) The operator presses the emergency stop button on the top of the car at the door of the landing to further prevent the elevator from running;

Even if there is a standardized process, due to various reasons, such as busy work, unskilled business, accidental negligence, some steps are ignored after the interruption of the operation process due to accidental reasons, etc., the actual operation is not completely in accordance with the standardized process

For example, when checking guide rails, guide shoes and oil cups, open the landing door and enter the car roof directly without pressing the emergency stop button, the operator thinks that the door lock switch is off when the landing door is opened, and the elevator will definitely not run; check pit parts and In the operation of the safety switch in the pit, if you do not press the emergency stop button when you open the landing door and enter the pit, the elevator may run after the landing door is closed, causing danger; the operator on the car top restored the emergency stop button, but did not set the inspection mode , at this time the elevator will respond to the landing call and move, causing danger

[0012]2) When multiple people work together in different positions, the cooperation is not good, and effective communication cannot be carried out when operating the elevator: for example, the personnel in the machine room ignore the car when they control the elevator to move upwards. There is an operator on the top of the car, so that the person on the car top is squeezed between the roof plate and the top of the car; the situation when entering the pit is similar

However, this elevator maintenance operation support system is relatively complicated, expensive, and poor in convenience, and obviously cannot be widely promoted.
