Description

Subway platform door electrical power generating system
Technical Field
The invention relates to the technical field of emergency power supplies, in particular to a power supply system for a subway platform door.
Background
For the power utilization environment of all important occasions, the state clearly requires realization of uninterrupted power supply, particularly in the subway industry, people flow is gathered, the personnel density is very high, and once the power supply is interrupted, personnel safety accidents and the operation abnormity of the whole subway line are easily caused. As an important component of uninterruptible power supply, how to avoid the battery becoming a single point of failure of the system and enhance the maintainability of the battery becomes an important research topic.
The subway station is usually of a two-side door structure, namely, the two-way operation subways respectively correspond to station doors and are respectively of a multi-side door structure; in the conventional scheme, two groups of power supplies are respectively connected with a driving bus and a control bus, the driving bus is simultaneously connected with two sides or a plurality of sides of a platform door, the control bus supplies power to a control system, and the control system controls the two sides or the plurality of sides of the platform door, so that two groups of batteries, namely a driving battery pack and a control battery pack, need to be configured to realize standby power during alternating current power failure, as shown in fig. 1 and 2. In general, the drive needs to provide the starting current of the motor, and a larger current is needed at the starting moment; the control system only sends control signals and communication signals, and the relative current is much smaller. Therefore, considering the economic factor, the capacity of the driving battery is generally about 3 times that of the control battery.
The above conventional scheme has several problems:
1. the battery is generally used in a plurality of series connection, and has the requirements of charging, discharging, detecting and the like, so that the number of wiring points is more, and the fault is easy to occur. The traditional platform door power supply system comprises two groups of battery cabinets, and as long as one group of batteries breaks down, system level faults are easily caused, so that the subway platform door cannot be normally opened. The subway operation frequency is high, the reaction time for field maintenance personnel is short, and finally passengers get on or off the train and the subway operation are affected;
2. the traditional scheme comprises a driving bus and a control bus, wherein the driving bus has large current due to the fact that a motor is arranged, and the current can reach hundreds of amperes at the moment of starting the motor, so that the power configuration and the capacitance capacity of the driving bus are far larger than those of the control bus, and the maintenance design is disturbed due to different configurations and different batteries;
3. the driving bus from the equipment room to the station door generates large voltage difference due to starting impact current, the voltage reaching the door unit is low, especially when the alternating current is in power failure, the battery voltage is lower than the power supply voltage, and the superposed line voltage drop possibly exceeds the power supply range of the motor, so that the bus wire diameter can be only thickened to be large, and great difficulty is caused to the field wiring design and installation;
4. the battery can be maintained or replaced at night after a problem occurs, so that the probability of alternating current power failure in the running process cannot be eliminated.
Disclosure of Invention

In order to solve the technical problems, the invention adopts a technical scheme that:
a power supply system for subway platform doors comprises a first platform door battery, a second voltage drop generating unit and a platform module;
the first main output end of the first platform door battery is connected with the platform module;
and the second standby output end of the second platform door battery is connected with the platform module through the second voltage drop generating unit.
The invention has the beneficial effects that: through setting up the first main output of first platform door battery and being connected with the platform module, the second is equipped with the output and produces the unit through the second pressure drop and be connected with the platform module, when two sets of platform door batteries all had no trouble, the voltage on the platform module is the same, if the battery is for the power supply of another side door, can produce the pressure drop on the pressure drop produces the unit, so the platform door battery can not give the power supply of offside platform module during normal work, and when certain a set of battery trouble, and when having a power failure, another a set of battery alright supply power for the platform module of battery trouble through being equipped with the output, with this realization two sets of batteries are each other for reserve, thereby when having a power failure and battery trouble, avoided subway platform door can't open and lead to the emergence of shut down the phenomenon.
