The invention discloses a device and method for improving the security of communication and transmission of existing signal devices. The method includes: during normal communication between various signal devices, monitoring the bit error rate of message transmission in real time to obtain information available for operation. Information about the operating environment of the signal equipment used by maintenance personnel during inspection. The invention adds the function of real-time monitoring of the bit error rate, provides the information of the operating environment of the signal equipment, and can be used by the operation and maintenance personnel when checking the equipment. The present invention does not need to modify the system software of the signal equipment, only the connecting wire is changed to a plastic optical fiber on the hardware, the cost of equipment modification is low, and the implementation and operation and maintenance work are simple and easy to use. Since the optical fiber uses visible light for transmission, it is not affected by electromagnetic interference, which can reduce the bit error rate during the transmission process, thereby improving the reliability of the signal equipment. The invention can improve the safety of the signal equipment, so that it can meet the quantitative calculation index of the failure rate of the safety transmission system in EN50159:2010.
Description
technical field [0001] The invention relates to the field of urban rail transit, in particular to a device and a method for improving the safety of communication and transmission of existing signal equipment. Background technique [0002] Urban rail transit first entered China in 1969. After decades of steady development, it has become the main travel choice for people and plays an important role in China's urbanization development. As an important part of urban rail transit, signal equipment is responsible for ensuring the safety of trains. However, because some of the existing signal equipment is old and has a long running time, the equipment on some lines has even reached the service life of more than 20 years. After years of use of these devices, various problems have gradually been exposed, and many signal products are also facing the needs of upgrading. The signal system is distributed in stages and steps to complete the modification and upgrade. [0003] see figur...
