Abstract
The utility model discloses a rail track temporary speed-limit caution device, comprising a radio frequency card (1), a card reader (2) and an alarm device (3). The card reader (2) is connected with the alarm device (3); the radio frequency card (1) is mounted on both sides of the rail track in the temporary speed-limit section or on the ground in the middle of the rails; the card reader (2) and the alarm device (3) are mounted on the train; the alarm device (3) adopts an audio or illuminating method to draw the attention of the train driver; the radio frequency card (1) is made into an active radio frequency card with a monolithic integrated radio receiving and sending module nRF24L01 as the core. The utility model is applicable to the temporary speed-limit section of the rail track.
Description
Technical field
The utility model relates to the mechano-electronic field, and a kind of railway line temporary speed limitation alarming device is provided especially.
Background technology
In order to guarantee the safe in operation of train, the train that moves at the railway line construction section needs temporary speed limitation.Be provided with warning marks such as band T prefix movable signal deceleration board and movable signal deceleration board in the place ahead of temporary speed limitation section, the trainman is when handling locomotive operation, need Shi Shi lookout, in time find movable signal deceleration board, and handle the locomotive deceleration by the temporary speed limitation section according to the requirement of deceleration board.If Si Ji lookout is not enough, fail to find timely and accurately warning marks such as movable signal deceleration board, just may cause the train hypervelocity to enter the temporary speed limitation section, train operation accident takes place.
For addressing the above problem, the utility model provides a kind of railway line temporary speed limitation alarming device, and before train entered the temporary speed limitation section, prompting driver the place ahead speed-limiting messages was avoided the generation of this type of train operation accident to greatest extent.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of railway line temporary speed limitation alarming device is provided especially.
The utility model provides a kind of railway line temporary speed limitation alarming device, it is characterized in that: include radio-frequency card 1, card reader 2, warning device 3; Wherein card reader 2 is connected with warning device 3; Radio-frequency card 1 is installed on temporary speed limitation section railway both sides or the middle ground of rail, and card reader 2, warning device 3 are installed aboard; As shown in Figure 1.
Described railway line temporary speed limitation alarming device, warning device 3 adopts the mode of voice mode or bright lamp, reminds train driver.
It is the active radio-frequency card of core that described railway line temporary speed limitation alarming device, radio-frequency card 1 are made into monolithic integrated wireless transceiver module nRF24L01; Comparing with other radio-frequency card of this radio-frequency card has following characteristics: effective communication distance, working stability, environmental concerns is little, circuit is simple, good reliability, as Fig. 2, and Fig. 3, shown in Figure 4.
Advantage of the present utility model: simple in structure, reliable in function, communication distance is far away, can be provided with according to environment and in time make prompting.
