But the disadvantages are: the sensor placed on the car top needs to be learned all the way, and the main controller has a single function
Because it is a no-load test, the link of repeatedly moving weights is omitted, and the t...

Embodiment Construction

[0070] The present invention will be further described below in conjunction with accompanying drawing.

[0071] Such as figure 1 and figure 2 The elevator balance coefficient testing system shown includes a detection transmitter 1 , a wireless locking current collector 2 , a mobile terminal 3 , a server 4 and a printer 5 .

[0072] The detection transmitter 1 is installed on the counterweight frame 10 of the elevator, and is used to judge whether the car and the counterweight 8 are at the same horizontal position when the elevator is loaded with different loads and runs straight up and down the whole process. , if yes, the detection transmitter 1 sends out a wireless signal.

[0073] The wireless locking current collector 2 is installed on the elevator main circuit 9, and is used to receive the wireless signal sent by the detection transmitter 1, and based on the wireless signal to collect the current value of the elevator drive motor at the moment, the wireless locking cur...

Abstract

The invention discloses an elevator balance coefficient test system and method. The elevator balance coefficient test system comprises a detection emitter, a wireless locking current collector and a mobile terminal, wherein the detection emitter is installed on an elevator counterweight frame and used for judging whether an elevator cage and a counterweight are located at the same horizontal position or not when an elevator carrying different loads straightly moves up and down in the whole course and sending out a wireless signal if yes. The wireless locking current collector is installed on an elevator main circuit and used for receiving a wireless signal and collecting a current value, at the moment, of an elevator driving motor based on the wireless signal, and is wirelessly connected with the detection emitter. The mobile terminal is used for receiving the current value collected by the wireless locking current collector, drawing a curve according to the received current values of different loads through a least square fit and interpolation integrated method, calculating a balance coefficient value, and displaying a test curve and a test result, and is wirelessly connected with the wireless locking current collector. By means of the elevator balance coefficient test system and method, accuracy of a balance coefficient test can be improved, and test efficiency is high.

Description

technical field [0001] The invention belongs to the test technology for the balance coefficient of a traction elevator, and in particular relates to a test system and method for the balance coefficient of an elevator. Background technique [0002] GB / T10059-2009 "Elevator Test Methods" and "Elevator Supervision Inspection and Periodic Inspection Rules - Traction and Forced Drive Elevators" require the balance coefficient of the elevator to be 0.4 to 0.5 or meet the design value of the manufacturing (transformation) unit. The inspection method "The car is loaded with 30%, 40%, 45%, 50% and 60% of the rated load for the whole journey up and down. When the car and the counterweight run to the same level, record the current value of the motor. Draw the intersection of the current-load curve and the downward running curve to determine the balance coefficient." The specific operation steps of this method in the inspection are: [0003] (1) When the elevator car and the counterwei...
