Research and Application of Remote Control of Four-Screen Display Equipment Based on Rail Transit Platforms
The four-screen monitoring and display equipment,decoding equipment,and image synthesis equipment for urban rail transit platforms are all installed on the platform.Once a malfunction occurs,maintenance time is tight and high-altitude operations on small platforms are difficult.Therefore,it is necessary to use remote control to quickly handle platform faults or perform redundant switching of decoding equipment.The testing and research of existing equipment on site can be remotely controlled through two methods:On-site infrared remote control or local area network control in the operation control center network management room,to achieve switching between primary and backup decoders and switching between image synthesis modes.By comparing and analyzing the transformation cost,implementation difficulty,and problem-solving efficiency of two control methods,it was found that the transformation cost of the local area network remote control method was slightly higher than that of the infrared remote control transformation method,but its application effect was far better than that of the infrared remote control transformation method.Using the existing local area network for remote control transformation can more effectively improve the fault handling efficiency of the fault decoder and the convenience of switching the redundancy mode of the decoder.
