Description

Technical Field

[0001] The present invention belongs to the field of high-speed rail earthquake monitoring, early warning and emergency response demonstration system, and is mainly used to simulate real-time earthquake monitoring and early warning of high-speed rail operation, and to control high-speed rail trains according to earthquake monitoring and early warning results. Background Art

[0002] Safety is the foundation of railway transportation. High-speed railways have higher requirements for the driving safety guarantee system due to the high-speed and high-density operation of trains. When countries around the world build high-speed railways, establishing a high-speed railway safety monitoring system is one of the key technologies that must be solved. Among the many natural disasters that endanger the safe operation of high-speed railways, earthquakes are a sudden disaster with a low probability of occurrence but the greatest harm. When the train is running at a low speed, the harm of earthquakes is not very prominent; but because the lateral force between the wheel and the rail is proportional to the square of the train's running speed, when the speed exceeds 200km / h, even a small earthquake may cause a major safety accident such as train derailment or even overturning. In the operation of high-speed railways, if the invasion of earthquake waves can be predicted tens of seconds in advance, an early warning can be issued, and the train can be braked quickly, the safety of passengers' lives and property can be guaranteed to the greatest extent.

At present, the high-speed railway earthquake monitoring and early warning system is mainly used in outdoor applications. If there are safety hazards in the actual outdoor operation, it will cause significant losses. In view of this, it is necessary to propose a high-speed railway earthquake monitoring and early warning and emergency response device. This model can simulate the operation of high-speed railways under earthquake conditions, and can conduct simulation experiments that are not allowed to actually occur, thereby providing experience accumulation and technical support for the safe operation of high-speed railways in earthquake environments, reducing or avoiding safety accidents in practice, and reducing property losses and passenger life risks.

The system includes: a wave output device 1, a vibration device 2, a high-speed rail sand table platform 3, an acceleration sensor 4, and a high-speed rail earthquake monitoring cabinet 5; wherein:

[0040] The wave output device 1 is connected to the vibration device 2. The wave output device 1 stores historical earthquake waveforms in advance and outputs at least one of the historical earthquake waveforms to the vibration device 2. The wave output device 1 stores a large number of historical real earthquake waveforms, and can simulate the situation of an earthquake when no earthquake occurs outdoors.

[0041] The vibration device 2 is connected to the high-speed rail sand table platform 3. The vibration device 2 generates vibration according to the historical earthquake waveform, driving the high-speed rail sand table platform 3 to vibrate. The structure of the vibration device 2 can be designed according to actual conditions, and in this embodiment, a vibration motor is preferably used.

[0042] The high-speed rail sandbox platform 3 includes a high-speed rail model 31 and a high-speed train model 32, which are used to simulate the actual high-speed rail operation; wherein, the high-speed rail train model is installed on the high-speed rail model 31, and a certain voltage is applied between the rails of the high-speed rail model 31 to drive the high-speed train model 32 to operate.

[0043] The acceleration sensor 4 is installed on the high-speed rail sand table platform 3. The acceleration sensor 4 vibrates with the vibration of the high-speed rail sand table platform 3 to generate an acceleration signal. In some embodiments, the acceleration sensor adopts the CT1500L type with a sensitivity of 5V / G. The sensor is suitable for ultra-low frequency vibration measurement, has high resolution, and is suitable for large structures, bridges, high-rise buildings, etc. Its output is a 4-20mA current signal, which is output as a signal after the I / V change.

[0044] One end of the high-speed rail earthquake monitoring cabinet 5 is connected to the acceleration sensor 4, and the other end is connected to the high-speed rail sand table platform 3. The high-speed rail earthquake monitoring cabinet 5 receives the acceleration signal, processes and analyzes it, and outputs a control signal to control the operation of the high-speed train model 32. Among them, the high-speed rail earthquake monitoring cabinet 5 determines the earthquake warning level according to the preset acceleration signal threshold and outputs a control signal. When the acceleration signal value is less than the threshold, the train runs normally. When the acceleration signal value exceeds the threshold, the train is controlled to slow down or stop.

[0045] The high-speed rail earthquake monitoring, early warning and emergency response demonstration system of the present invention has a simple structure, is easy to use, and can simulate the operation of high-speed rail under earthquake conditions without the actual occurrence of an earthquake. After receiving the earthquake wave, the acceleration signal generated by the acceleration sensor 4 can be used to judge the intensity of the earthquake, and the hazard of the earthquake to the high-speed rail can be judged based on the intensity. The operation of the high-speed rail is controlled according to the magnitude of the hazard, providing experience accumulation and technical support for the safe operation of the high-speed rail in an earthquake environment in actual situations, which can reduce or avoid safety accidents in actual applications, reduce property losses and passenger life risks. For example, as shown in Table 1, the acceleration signals corresponding to various earthquake waves and the control of the train are made into corresponding tables to provide technical references for future high-speed rail operations.

[0047] Table 1

[0048] In some cases, when an earthquake really occurs, if the real earthquake waveform can be detected in time and accurately, the waveform can be matched with the historical earthquake waveform pre-stored in the wave output device 1. If the match is successful, the situation in Table 1 can be directly used to judge the impact of the earthquake on the high-speed rail, so as to take appropriate control methods for the high-speed rail. Compared with the prior art, the early warning analysis time for the arrival of an earthquake is reduced. If an early warning can be given, the loss of property and the danger to the lives of passengers can be greatly reduced. It can be understood that the system of the present invention can also be applied to rail transportation such as subways and trains.
