The invention relates to the technical field of elevator equipment, in particular to a brake detection method and system for a frequency converter of a construction elevator. Through structural cooperation among the extrusion assembly, the driving assembly, the micro-touch assembly A, the micro-touch assembly B and the detection control system, that is, an elastic piece deforms downwards after being pressed and makes contact with a micro-touch switch A fixed to the upper surface of the fixing plate, then the micro-touch switch A is driven to work, and when the micro-touch switch A works once, a counter counts once, so that the working efficiency is greatly improved. Meanwhile, after the pressure sensor is pressed, pressure data can be obtained, the number of times recorded by the counter and the pressure data obtained by the pressure sensor are transmitted to the information processor to be converted into signals, the signals are transmitted to the PC end through the communication module, and finally the PC e
