Abstract

Inside a railway train, a wall or door is set between the non-restricted carriage and the restricted carriage for separation, including the instruction system, execution system and server. The said instruction system comprises a passenger counting unit, a gate instruction unit and a storage unit; the said execution system comprises a gate control unit arranged on a riding area computer at the next station; and the passenger counting unit transmits the total number of passengers that have entered the restricted carriage to the gate instruction unit. The gate instruction unit obtains the gate instruction based on the total number of passengers that have entered the restricted carriage. The gate control unit of the riding area computer at the next station also executes the gate instruction, so as to control the number of passengers that have entered the riding area within the maximum number of passengers.

First claim

What is claimed is:

1. A database system for controlling the gate of subway riding area comprises a railway train, wherein the railway train is composed of non-restricted carriages with non-restricted number of passengers and restricted carriages with restricted number of passengers, each of the restricted carriage is a carriage with a constant maximum number of passengers, a wall or door is arranged between the non-restricted carriages and the restricted carriages for separation, the riding area for the non-restricted carriages is located in the middle of a platform, the riding area for the restricted carriages is located at one or both ends of the platform, the platform is provided with riding area entry and exit gates as well as fences to divide the platform into the riding area for the non-restricted carriages and the riding area for the restricted carriages, wherein the database system comprises:
an instruction system, an execution system and a line server; wherein the instruction system comprises a gate instruction unit that is composed of a passenger counting unit, a gate instruction subunit and a storage unit;
wherein the execution system comprises a gate control unit arranged on a computer in the riding area for the restricted carriages of the next station;
wherein the passenger counting unit is connected to the gate instruction subunit and configured to record the total number of passengers that have entered the restricted carriages from a train's arrival time to the departure time;
wherein the gate instruction subunit is configured to obtain a gate instruction based on the total number of passengers that have entered the restricted carriages from the passenger counting unit;
wherein the gate instruction unit is connected to the gate control unit arranged on the computer in the riding area for the restricted carriages of the next station and configured to transmit the gate instruction to the gate control unit arranged on the computer in the riding area for the restricted carriages of the next station;
wherein the gate control unit arranged on the computer in the riding area for the restricted carriages of the next station comprises executing the gate instruction to ensure that the number of passengers that have entered the riding area for the restricted carriages reaches up to the constant maximum number of passengers.

2. The database system for controlling the gate of the subway riding area specified in claim 1 , wherein the said instruction system comprises computer arranged in the riding area, on-board computer or server.

3. The database system for controlling the gate of the subway riding area in claim 1 , wherein
the passenger counting unit comprises a vehicle arrival and departure sensor, a restricted carriage entry passenger counter, a restricted carriage exit passenger counter and a passenger counting subunit.

4. The database system for controlling the gate of the subway riding area in claim 3 , wherein
the passenger counting unit is designed to calculate the total number of passengers that have entered the restricted carriage from the time when the door opens to the time when it closes based on the number of passengers, transmitted by the restricted carriage entry passenger counter, that have entered the restricted carriage from the time when the door opens to the time when it closes as well as the total number of passengers, transmitted by the restricted carriage exit passenger counter, that have exited the restricted carriage from the time when the door opens to the time when it closes;
wherein total number of passengers that have entered the restricted carriage=the number of passengers that have entered the restricted carriage from the time when the door opens to the time when it closes−the number of passengers that have exited the restricted carriage from the time when the door opens to the time when it closes The total number of passengers that have entered the restricted carriage from the time when the door opens to the time when it closes shall be transmitted to the gate instruction subunit.

5. The database system for controlling the gate of the subway riding area in claim 3 , wherein
the restricted carriage entry passenger counter, the restricted carriage exit passenger counter and the passenger counting subunit include a video passenger flow counter;
the video passenger flow counter is configured to record the number of passengers that have entered the restricted carriage, the number of passengers that have exited the restricted carriage, and the total number of passengers that have entered the restricted carriage, and to transmit the total number of passengers that have entered the restricted carriage to the gate instruction subunit, and to store the number of passengers that have entered the restricted carriage in the “Table of Passengers that Have Entered the Restricted Carriage” of the storage unit; this is a video passenger flow counter-type passenger counting unit, referred to as passenger counting unit for short, which includes the video passenger flow counter connected to a door sensor.

6. The database system for controlling the gate of the subway riding area in claim 5 , wherein
the video passenger flow counter comprises the upper part of the platform corresponding to the parking position of the carriage door of the restricted carriage in the riding area for the restricted carriages, or the upper part of the position corresponding to the door of the restricted carriage in the carriages.

7. The database system for controlling the gate of the subway riding area in claim 1 , wherein
the storage unit stores the original number of passengers and the preset number;
wherein original number of passengers is the number of passengers in the restricted carriage before the door opening time of the carriage in the station, and the preset number is the preset number of passengers that will enter the riding area for the restricted carriages of the next station.

8. The database system for controlling the gate of the subway riding area in claim 1 , wherein
the gate instruction unit comprises a gate instruction algorithm, and the function of the said gate instruction algorithm includes a gate instruction sent to the execution system of a computer in the riding area for the restricted carriages of the next station according to the existing number of passengers and a preset number.

9. The database system for controlling the gate of the subway riding area in claim 1 , wherein
the storage unit stores Riding Area Operation Table or Vehicle Operation Table;
the Riding Area Operation Table includes: table index number: riding area number, and table contents: vehicle number, arrival sequence of vehicles, time of vehicle arriving at the platform, original number of passengers and preset number;
the Vehicle Operation Table includes: table index number: vehicle number, table contents: riding area number, arrival sequence of vehicles, time of vehicle arriving at the platform, original number of passengers and preset number.

10. A method for controlling a gate command algorithm for limiting the number of carriage passengers in a super-platform subway to a limit number adapt to the database system for controlling the gate of the said subway riding area specified in claim 1 , wherein
the preset number is the number of passengers who are allowed to enter the next riding area preset by the line server or preset according to a certain law and big data;
wherein zn platform represents any platform, and zn+1 platform represents the next continuous platform in the forward direction of any platform; cn restricted carriage represents an arbitrary restricted carriage, and cn+1 restricted carriage represents a
