Abstract
The utility model belongs to an automatic alarm device, in particular to an automatic alarm device for railway signal violation. The automatic alarm device comprises a signal machine, and two axle counters sensors arranged at two sides of the signal machine; the signal machine and the axle counter sensors are connected by a Siemens S7212PLC; the Siemens S71212PLC is connected with a horn and an alarm lamp by a relay and is connected with an alternating current power supply and a direct current power supply. A power switch is arranged between the alternating current power supply and the direct current power supply. The state information of the signal machine is collected by the axle counter sensors mounted on a steel rail on site, when a locomotive wrongly violates the signal, the information is transmitted to the PLC for automatic logic operation, and the automatic alarm of the voice horn and a flashlight is realized.
Description
Technical field
The utility model belongs to autoalarm, and specifically a kind of railway is rushed signal autoalarm.
Background technology
When locomotive is rushed RST, if alarm free device can cause accidents such as squeezing trouble, locomotive rollover, hostile collision, cause great personnel, equipment breakdown loss, affect larger.
Summary of the invention
Technical problem to be solved in the utility model is: how by Real-Time Monitoring locomotive, to rush signal information, note abnormalities and point out trainman emergency braking by audio alert, avoid the generation of accident.
The technical scheme that the utility model adopts is: a kind of railway is rushed signal autoalarm, comprise signal, be arranged on two axle count sensors of signal both sides, described signal is connected by Siemens S7212 PLC with two axle count sensors, described Siemens S7212 PLC connects loudspeaker and alarm lamp by relay, described Siemens S7212 PLC connects source of AC and direct supply, between direct supply and source of AC, has source switch.
As a kind of optimal way: direct supply is storage battery.
As a kind of optimal way, it is characterized in that: relay, loudspeaker, alarm lamp connect direct supply.
The beneficial effects of the utility model are: when locomotive is rushed RST, if alarm free device, can cause accidents such as squeezing trouble, locomotive rollover, hostile collision, cause great personnel, equipment breakdown loss, affect larger, if by the meter shaft collection signal machine status information that rail is installed at the scene, when locomotive is rushed after signal, information is passed to PLC and carry out automatic logic operation, realize the automatic alarm of speech horn, flash light, timely prompting driver emergency braking, avoids the loss of the generation of accident and personnel, equipment.Adopt axle count sensor, accurate collection site status information, data are accurately real-time, utilize PLC to carry out logic operation, and speed is fast, does not need additionally to add CPU device and carries out computing, compact to design, and saving resource is convenient to realization.The utility model adopts AC/DC double-purpose electric source to Siemens S7212 PLC, has avoided AC dump or the too fast problem of direct-flow storage battery consumption, and relay, loudspeaker, alarm lamp connect direct supply and guaranteed that device is in real time in running state.
Accompanying drawing explanation
Fig. 1 is electrical block diagram of the present utility model;
Wherein, 1, axle count sensor, 2, signal lamp, 3, Siemens S7212 PLC, 4, source of AC, 5, source switch, 6, relay, 7, direct supply, 8, loudspeaker, 9, alarm lamp.
The specific embodiment
As shown in Figure 1, a passive axle count sensor is respectively installed in the rail inner side, 300mm place of signal both sides, passive axle count sensor is electrically connected to the blue lamp line of signal lamp, the signal status information transmission gathering is to Siemens S7212 PLC, by the priority current impulse of two passive sensors, determine the direction that locomotive advances, by the blue lamp line inducing current of signal, determine whether signal is opened, if signal is not open and vehicle sails into, PLC controls alarm relay adhesive, and speech horn and warning indicator lamp are reported to the police.With AC/DC double-purpose electric source, to Siemens S7212 PLC, avoided AC dump or the too fast problem of direct-flow storage battery consumption, relay, loudspeaker, alarm lamp connect direct supply and have guaranteed that device is in real time in running state.
Claims (3)
