Abstract
The invention relates to a vehicle-mounted embedded type side air pressure and visibility real-time monitoring system of a motor train unit, comprising a side air pressure monitoring system and a visibility monitoring system. In working, a sensor transmits a signal to a microprocessor; the microprocessor analyzes and processes electric signals carrying out air pressure acquisition at both sides of the motor train unit through an intermediate temperature difference sensor and an air speed and air pressure converting device and computes to obtain a result by authoring software according to a certain algorithm; a pulse lidar monitors visibility in real time, wherein two monitoring results are displayed on a display screen, if the monitoring results exceed the range of a safe value, an alarm device sends an alarm, and alarm information is displayed on the display screen; and the signals are transmitted to a railway commanding and dispatching room for alarm and display through RS-232/RS-485/general packet radio service (GPRS)/code-division multiple access (CDMA) duplex communication.
Description
Technology neck or
The present invention relates to the affiliated facility that the railway motor train unit is used, a kind of specifically motor train unit that crosswind pressure and visibility monitoring system are arranged.
Background technology
If motor train unit runs into strong wind in the process type of advancing, when mainly being the threat of side direction wind,, the danger that is blown over by wind is just arranged if there is not timely ramp to stop, can cause the massive losses of personnel and property.Therefore, must strengthen monitoring and prediction work, prevent that tragedy from taking place.
In addition, if motor train unit runs into heavy rain, dense fog in the process type of advancing, its visibility is very low, can't see the road conditions in train the place ahead clearly, as obstacle ramp to stop immediately, can cause car to turn over the tragedy that the people dies equally.And wind and rain tends to occur simultaneously, therefore, must monitor simultaneously and forecast it.
Show from the related data retrieval that comprises Chinese patent, have not yet to see the relevant report that front end or side in motor train unit are provided with monitoring probe.
Summary of the invention
In order to prevent that strong wind dense fog heavy rain from causing serious threat to motor train unit, the objective of the invention is behind the windscreen glass of motor train unit, to be provided with the infrared monitoring probe size of monitoring rainfall; Place roof to survey visibility with pulse lidar; Offer reference driver and decision-making, reach the purpose of safe driving.
The technical solution adopted for the present invention to solve the technical problems is: the head of a motor train unit is arranged, a two open ends is arranged backward in the head, the pipeline that the centre communicates is equipped with differential pressure pick-up in the middle of pipeline.Wind-force monitoring differential pressure pick-up will be in being connected with microprocessing systems.It is rain sensor that top in the front windshield of head is installed with an infrared rainfall monitoring exploration head, and the rainfall monitoring probe also is connected with microprocessor.
Sensing reached microprocessor with signal when 1, the present invention worked, microprocessor will be analyzed, handle the air pressure signal that collects of motor train unit both sides by middle temperature difference pressure sensor, and calculate by writing software by certain algorithm, the result who obtains is shown on liquid crystal display.Infrared rain sensor is monitored the rainfall of front windshield, and microprocessor comes the current rainfall situation of computational analysis according to the umber of pulse of exporting on the rainfall monitoring probe receiver, and the result who obtains is shown on liquid crystal display.The result who more than obtains is as exceeding the safety value scope that sets, and microprocessor will output signal to acoustic-optic alarm and report to the police, and by the RS-232/RS-485/GPRS/CDMA duplex signal be transferred to the railway operations tower simultaneously, and reports to the police and demonstration.
2, the invention has the beneficial effects as follows: because the present invention has installed monitoring probe at the head both sides and the front end of motor train unit, like this motor train unit wind-force and visibility in operational process there has been reliable real-time on-site dynamic monitoring, the situation of monitoring is presented on the liquid crystal display through microprocessor in real time, when blast or rainfall surpass one regularly, promptly can give the alarm, propose driver's deceleration or parking, in order to avoid car turns over the accident generation that the people dies.Therefore, the present invention can reach predetermined purpose.

Embodiment
Below in conjunction with specification drawings and specific embodiments content of the present invention is elaborated:
With reference to figure, differential pressure pick-up is by the pressure differential of monitoring train two sides in the wind-force monitoring system, and after pressure differential is converted to voltage signal, by after microprocessor 5 calculating result being presented on the display screen 6, if the wind-force measured value surpasses the safety value scope set then sends audible and visible alarm by warning device 7, and on display screen 6 display alarm information.
With reference to figure, rainwater drops on the front windshield 3 in the rainfall monitoring system, infrared rainfall monitoring probe 4 receivers receive the reflected light of transmitter, the power that the rainfall size variation influences the reflects infrared light that receiver receives changes, thereby there is certain relation in influence output pulse change between them.Monitoring processing by the output pulse of 5 pairs of infrared rainfall monitoring probe 4 receivers of microprocessor calculates, the result is presented on the display screen 6 with the rainfall size, if rainfall size surpasses the safety value scope that sets then is given the alarm by warning device 7, and on display screen 6 display alarm information.
With reference to figure, pulse lidar is surveyed visiometer 9 and is contained on the roof, the signal that real-time monitors is sent to microprocessor 5 and handles, the visibility size is presented on the display screen 6, by the RS-232/RS-485/GPRS/CDMA duplex signal is transferred to the railway operations tower simultaneously, and report to the police and demonstration.
