At present, rail transit becomes an indispensable transportation mode for urban citizens to go out, and forms a core framework of urban traffic together with traditional road transportation.
The rail transit in each city bears the transportation capacity requirement of thousands of people every day, so the safety of the rail transit becomes the most important index. Further, a brake control system for rail transit becomes very important.
In the existing track brake monitoring system, an information transmission channel is often established in a wired connection mode. The wired transmission has the advantages of high speed and stability, and is not easy to cause signal distortion and even equipment disconnection. However, due to the particularity of rail transit, the unit length of the information transmission platform is too high in cost in a limited connection building mode, the cost is difficult to control, application scenes are limited to a certain extent, and wired connection cannot be well adapted when scenes such as acid-base exceeding and temperature exceeding are faced. Furthermore, the brake monitoring system which is built in a limited connection mode has a large demand on electric energy, and once the power supply is insufficient in reserve, the whole system can be in an endangered paralysis state.
In addition, the most important function of the rail transit brake monitoring system is the monitoring and early warning function of foreign matters in the rail in the driving process. Although the running tracks of the rail transit are relatively closed, the situation that pedestrians cross the running tracks hardly occurs. However, the related facilities and equipment in the running track are more, and after the equipment works with load for a long time, the problem that the equipment and the line age so that objects fall down is inevitable. Because the train in the rail transit is travelling fast, and the field of vision is dim in the track, in case there is the thing that drops on the driving track, the train person will not be in time to make emergency braking's reaction in order to avoid little danger at all. Therefore, a set of brake monitoring system is needed in the rail transit to complete the function of warning transmission.
In summary, the brake control system for rail transit is implemented by adopting a technical means that comprehensively considers various influence factors such as transmission stability, transmission speed, construction cost and application scene.

Detailed Description
The technical solution of the present invention is further specifically explained by the following embodiments with reference to the attached drawings.
As shown in fig. 1, the present embodiment implements a bus-type rail transit brake monitoring system, which includes a monitoring management center, a terminal signal processor and an information acquisition terminal; one monitoring management center establishes communication connection with the plurality of terminal signal processors in a wireless communication mode, and one terminal signal processor establishes communication connection with the plurality of information acquisition terminals in a wireless communication mode.
In order to facilitate monitoring and operation of a driver, the monitoring management center is arranged in a cab of the train; the terminal signal processors are arranged on the wall and the ground surface of the rail running channel, and the interval between every two terminal signal processors is 50m along the direction of the running rail of the train; the information acquisition terminal is arranged on a track where the train runs.
Meanwhile, in this embodiment, a zigbee wireless communication protocol is used to establish a wireless connection between the monitoring management center, the terminal signal processor, and the information acquisition terminal. In order to meet the information acquisition work under different situations, the construction of the information acquisition terminal is completed in a mode of combining an infrared detection device and a laser detection device.
In addition, the monitoring management center is electrically connected with the emergency brake switch of the train cab, and if a driver cannot operate or does not receive information at all after receiving the emergency brake information, the monitoring management center can judge to take emergency brake measures according to an algorithm of the monitoring management center. The embodiment also discloses that the monitoring management center is provided with a voice alarm module, so that a driver can receive the message without observing a screen of the monitoring management center.
This embodiment is still right the utility model discloses monitored control system that locates has carried out the sight simulation: the train of the rail transit is in normal running. A dropped lead-zinc storage battery is clamped in a track at a position 100 meters ahead of a running train, and a train driver cannot see the dangerous situation at the position 100 meters ahead due to insufficient light and narrow visual field in the track. However, since the rail transit system implemented by the present embodiment has a bus type rail transit brake monitoring system, the dangerous situation has been resolved by the following steps:
the information acquisition terminal (laser detection device) of the system acquires that foreign matters exist on the track, and the size of the foreign matters exceeds the negligible minimum limit, so that the terminal signal processor sends a braking request and a related position label to the monitoring management center through information processing and analysis; after receiving the emergency braking signal, the monitoring management center controls the voice alarm device and the emergency braking switch to realize automatic emergency braking or braking alarm.
Because the ZigBee communication protocol is adopted in the system, the transmission delay and the transmission stability are far higher than those of the traditional wireless communication modes, such as a local area network, a blue et and the like; the cost and the diversity of the adaptive scene are far superior to those of the traditional limited transmission mode.
