specific Embodiment

[0059] Specific examples, such as Figure 3-4 , a train approaching alarm system, which includes: a locomotive radio installed on each train; a plurality of hand-held radios and an early warning server deployed in the duty room of each station. The specific system parameters are: based on the open standard developed by DMR ETSI (European Telecommunications Standards Institute) to meet the needs of middle and low-end professional and commercial users for mobile communications, using TDMA (double time slot) multiple access mode, 12.5 KHz channel spacing, 4FSK modulation mode, data transmission rate of 9.6Kb / s) protocol dispatching call system as the basis design early warning server, combined with the global positioning system (GPS) and geographic information system (GIS) of mobile portable terminals, passenger car operation safety The monitoring system (TCDS) monitors the position and speed of trains running online in real time, and aggregates the data of trains and constructio...

Abstract

The invention relates to a train approach early-warning system and method for railway safety protection. The train approach early-warning system comprises locomotive radios installed on each train andused for acquiring positioning information from GPS modules on respective trains, a plurality of hand-held radios used for sending real-time positioning information of early-warning targets corresponding to each hand-held radio to early-warning servers through an alarm channel and receiving the warning information issued by the early-warning servers, and the early-warning servers deployed in respective station duty rooms and used for communicating with each hand-held radio through the alarm channel and monitoring the real-time position of each early-warning target and the running informationof on-line running trains in real time, and simultaneously transmitting warning information to the warning targets when the distance between the on-line running trains and a certain warning target reaches the predetermined early-warning range. The train approach early-warning system can accurately judge whether the train enters the early-warning position, and can maximally guarantee the safe evacuation of the early-warning targets from the scene after an early warning is generated.

Description

technical field [0001] The invention relates to a railway train approaching warning technology, in particular to a train approaching warning system and method for railway safety protection. Background technique [0002] As the country increases investment in the construction of adding double tracks, introducing new lines, technological transformation and capacity expansion, the scale and quantity of railway construction adjacent to (passing) across business lines will also continue to increase. It provides an opportunity for railway construction enterprises to seize the share of operating income. However, the construction of railway business lines is in different ways, situations, categories and trains that are running all the time, restricting, interfering and influencing each other. A slight negligence in the construction may lead to a catastrophe, causing serious losses to the life and property of the country and the people. [0003] The construction of railway business...
