Embodiment Construction
[0017] The hardware structure of the portable subway screen door signal tester of the embodiment of the present invention is as follows figure 1 As shown, including power supply, keyboard, monitor, control unit, signal amplifying circuit and antenna. The function of the power supply is to realize the supply of the working power of the code generator and the management of charging and discharging of the battery; the keyboard and display realize the man-machine interface, and the main functions of the control unit include keyboard control, display control, high-speed DA control and communication functions. The control unit accepts the control of the keyboard and the upper computer; sends the content to be displayed to the display, and generates the sent message waveform according to the sending control, and sends it to the antenna sending unit.
[0018] The CPU of the control unit adopts TMS320DM6437 digital signal processing chip of TI Company. Its functional modules such as ...

The invention discloses a portable platform screen door signal tester. The portable platform screen door signal tester comprises a power supply, a keyboard, a display, a control unit, a signal amplification circuit and an antenna. The power supply realizes code sender working power supply and cell charging and discharging management. Through the keyboard, setting data and transmitting commands are input into the control unit. The control unit stores the setting data input by the keyboard, transmits contents needing to be displayed to the display, and generates a message wave needing to be transmitted according to the transmitting commands input by the keyboard. The message wave is transmitted by the signal amplification circuit and the antenna. Through the portable platform screen door signal tester, instructions needed in control of a platform screen door are set and transmitted under the no train condition, so that control, test, checking, maintenance and emergency treatment on the platform screen door can be carried out conveniently.
Description
[technical field] [0001] The invention relates to a subway screen door control system, in particular to a portable subway screen door signal tester. [Background technique] [0002] The subway automatic train control (ATC) system includes the train automatic driving subsystem ATO (automatic train control), which has the function of automatically controlling the screen door when the train arrives at the station. But when it comes to maintenance and emergency control, there is no proper coding control equipment. Before the opening of the subway, equipment suppliers brought their own large-scale code-issuing control locomotive equipment, which could not meet the maintenance functions of the subway. [0003] During the operation of the subway, only when the train arrives at the station, the ATP / ATO on-board unit sends an "open" or "close" signal to the screen door through the on-board PTI antenna, and the signal is received by the ground PTI (train position identification system...
