Abstract

The invention discloses a wireless control device and method for a train braking test system using an intelligent terminal. The device includes: an intelligent terminal that generates control information and sends control information to a computer control center through a router or receives feedback information sent by it; a computer The control center generates control instructions according to the control information and uses wired communication to send the control instructions to the wireless data transmission controller and the controllable exhaust device at the head of the brake pipe of the train to be inspected or generate feedback based on the measured wind pressure information sent by it Information; the wireless data transmission controller uses wireless communication through the wireless relay station to send control instructions to the controllable exhaust device in the middle and tail of the brake pipe of the train to be inspected or receive the measured wind pressure information sent by it; the train to be inspected The controllable exhaust devices at the head, middle and tail of the brake pipe detect the braking performance of the train according to the control instructions, and generate the measured wind pressure information. The technical scheme of the invention improves the working efficiency of the train braking test system.

Description

technical field [0001] The invention relates to a train vehicle braking test system. More specifically, it relates to a wireless control device and method for a train brake test system using an intelligent terminal. Background technique [0002] The importance of testing the braking performance of train vehicles for the safe operation of trains is self-evident. There are two main testing methods at present: one is to manually operate the JZ-T gate and test at one end of the train; the other is to use a microcomputer system instead of manual operation, output control signals to generate control air pressure, and obtain wind pressure through sensors Detection data, so as to complete the detection of the braking performance of train vehicles. [0003] The disadvantages of manual operation are high labor intensity, low efficiency, and poor reliability of test data; microcomputer system is used to complete the braking performance test. At present, wireless handheld encoder / code...
