The invention provides an input system provided with a reserved touch screen and used for a train operation monitoring system. The input system comprises a display main board, a keyboard input module and a touch screen input module, wherein the keyboard input module comprises a programmable logic device and a keyboard coupled with the programmable logic device. The touch screen input module comprises a touch screen and a serial peripheral interface analog-digital conversion module coupled with the touch screen. The touch screen is provided with a touch switch for controlling the opening and closing of the touch screen input module. The keyboard input module is configured into main input equipment of the input system, the touch screen input module is configured into reserved input equipment of the input system, and the touch switch is at a switched-off state under a default state.
Description
technical field [0001] The invention relates to an input system of a vehicle-mounted train control system, in particular to the design of a spare touch screen. Background technique [0002] The train operation monitoring system (LKJ) is the mainstream train safety equipment in China, and the input and output system is responsible for human-computer interaction as an important component. The input device is responsible for a series of information input such as parameter setting, data input, information query and locomotive control. Work, the input device is connected with the main board to realize the input function, and then realize the human-computer information interaction. [0003] Traditional LKJ input devices are realized by the following schemes, but they all have their own defects. [0004] Option 1 is a pure keyboard input method, and the input function is realized by pressing the keyboard keys. In this way, since the keyboard is the only input device, once the key...
