Abstract
The invention relates to a vehicular wind-force/rainfall automatic monitoring and alarming system for a motor train unit. The system comprises a wind-force monitoring system and a rainfall monitoring system. During the work, a sensor sends signals to a micro-processing system which takes a single chip microcontroller as a core control system. A medium-temperature pressure difference sensor is used for collecting air pressure at two sides of the motor train unit and converting the pressure difference into a voltage signal which is then output. After filtration, the voltage signal undergoes analog/digital conversion performed by an A/D converter and is connected into an I/O of the single chip microcontroller so that the voltage signal is analyzed and processed; and calculation is carried out by using a compilation software according to a certain algorithm so as to obtain a monitoring result. An infrared rain sensor monitors rainfall of a front windshield, and the single chip microcontroller calculates and analyzes a current rainfall condition according to the number of pulses output by a rainfall monitoring probe receiver. The monitoring results of the infrared rain sensor and the single chip microcontroller are displayed on a display screen. If the monitoring results exceed a safe value range, an alarming device alarms and the alarming information is displayed on the display screen.
Description
Affiliated technical field
The present invention relates to the affiliated facility that the railway motor train unit use, a kind of specifically motor train unit that have wind-force, rainfall monitor and early warning system.
Background technology
If motor train unit run into strong wind in the process of advancing, when mainly being the threat of side direction wind,, the danger that is blown over by wind is just arranged if in time do not stop, can cause the massive losses of personnel and property.Therefore, must strengthen monitoring and warning work, prevent that tragedy from taking place.
In addition, if motor train unit run into heavy rain in traveling process, its visbility is very low, can't see the road conditions in train the place ahead clearly, can not stop immediately as obstacle, 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 early warning it.
Show from the related data retrieval that comprises Chinese patent, have not yet to see the relevant report that front end or side at motor train unit are provided with wind-force, rainfall monitoring probe.
Content of the present invention
In order to prevent that crosswind and torrential rain from causing serious threat to motor train unit, the objective of the invention is and will be provided with monitoring probe at the front end and the side of motor train unit, the grade size of monitoring crosswind and rainfall offers reference driver and decision-making, reaches the purpose of safe driving.
The technical solution adopted for the present invention to solve the technical problems is: the head of 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 connected with microprocessing systems.It is rain sensor that top in the front windshield of head is installed with an infrared rainfall monitoring probe, and the rainfall monitoring probe also is connected with microprocessing systems.
Sensor reached microprocessing systems with signal when the present invention worked, and microprocessing systems is to be core control system with micro controller system (optional AT89S51).By middle temperature difference pressure sensor (optional PTP801H, three wire system) air pressure of motor train unit both sides is gathered, and its differential pressure is converted to voltage signal output, filtering shows the result who obtains after A/D converter (optional ADC0809) carries out inserting after mould/number conversion the I/O mouth of micro controller system signal is analyzed, handled and calculate by making software according to certain algorithm on LED or LCD.Infrared rain sensor is monitored the rainfall of front windshield, and micro controller system (optional PIC16F873) comes the current rainfall situation of computational analysis according to the pulse count of exporting on the rainfall monitoring probe receptor, and the result who obtains is shown on LED or LCD.The result who more than obtains is as exceeding the safety value scope that sets, and micro controller system will output signal to the jingle bell warning device and report to the police.
The invention has the beneficial effects as follows: because the present invention has installed monitoring probe at head two limits and the front end of motor train unit, like this motor train unit wind-force and rainfall in operational process there has been the dynamic monitoring of failure-free real-time on-site, the situation of monitoring is presented on LED or the LCD in real time through microprocessing systems, when crosswind is pressed or rainfall when surpassing certain rank, promptly can give the alarm, remind the driver to slow down or parking, in order to avoid car turns over the accident generation that the people dies.Therefore, the present invention can reach predetermined purpose.
Description of drawings
The present invention is described further below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a wind-force monitoring scheme block scheme.
Among Fig. 1,1 is head, and 2 is the wind-force differential pressure pick-up, and 3 is front windshield, and 4 is infrared rainfall monitoring probe, and 5 is microprocessing systems, and 6 is read-out, and 7 is warning device, and 8 is lead.
The specific embodiment
With reference to Fig. 1, differential pressure pick-up is by the difference of pressure of monitoring train side in the 2 wind-force monitoring systems, and after difference of pressure is converted to voltage signal, after the A/D converter conversion, by after microprocessor 5 computings result being presented on the read-out 6, if the wind-force observed reading surpasses the safety value scope set then is given the alarm by warning device 7, and on read-out 6 display alarm information.
With reference to Fig. 1, rainwater drops on the front windshield 3 in the rainfall monitoring system, infrared rainfall monitoring probe 4 receptors receive the reflected light of projector, the rainfall size variation influences strong and weak variation of reflects infrared light that receptor receives, 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 receptors of microprocessor calculates, the result is presented on the read-out 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 read-out 6 display alarm information.
