on the intelligent mobile terminal, open APP analysis software, the screen display main menu interface includes: setting an elevator model, an elevator number, a rated speed, a running direction and a test mode; the test mode is dynamic test or static test;
s240, displaying a test result;
selecting a dynamic test mode, displaying the running speed of the elevator in real time in the test process, and displaying the maximum running speed of the elevator, the maximum acceleration and the braking distance in the braking process on a screen after the test is finished;
four options of 'curve', 'printing', 'sharing' and 'returning' are set on the test result interface:
clicking a 'curve' button, and simultaneously displaying the speed, acceleration and displacement curves of the whole process from starting to stopping of the elevator by a screen;
clicking a 'print' button, firstly popping up a connection interface of the Bluetooth printer, and after the connection is successfully operated according to a prompt, printing a test result by the Bluetooth printer;
clicking a sharing key, calling a sharing function of the intelligent mobile terminal, and sharing a test result to a related account of the social software such as WeChat, QQ and nailing;
clicking the 'return' button returns to the upper menu.
9. The no-load test method for 1.25 times braking test of the traction elevator according to claim 8, characterized in that:
in step S210, the elevator speed measuring mechanism is installed on a speed governor (11) in an elevator machine room, and specifically includes:
firstly, an elevator speed measuring mechanism (12) is pre-installed on one side of a speed limiter (11) through a magnetic seat (122), then a swinging guide groove (123) is installed at a position capable of accommodating a speed measuring wheel (131) along an arc groove of an installation support (121) according to the space on a wheel disc (111) of the speed limiter, then a speed detector (13) is installed on an instrument installation shell (124), the speed measuring wheel (131) is ensured to be above the wheel disc (111) of the speed limiter, then a bolt on a lower pressing plate (125) is rotated to enable the lower pressing plate (125) to fix the instrument, finally a guiding and adjusting shaft (127) is finely adjusted up and down to enable the speed measuring wheel (131) to be in close contact with the wheel disc of the speed limiter (11), then a fastening bolt on the swinging guide groove (123) is rotated to fasten the guiding and adjusting shaft (127) in the swinging guide.
