[0020] The server instruction unit or the on-vehicle computer obtains the corrected permitted passenger number based on the total number of passengers outside the outbound carriages, the predetermined number, and the algorithm for correcting the permitted passenger number; the total number of passengers outside the outbound carriages = the number of passengers in the waiting carriages at the moment of the closing time of the train at this station recorded by the video passenger flow counter or the static video passenger counter in the waiting carriages + the number of passengers outside the outbound carriages recorded by the outbound carriages counter from the closing time of the train at this station to the opening time of the train at the next station - the number of passengers in the inbound carriages recorded by the inbound carriages counter from the closing time of the train at this station to the opening time of the train at the next station;

[0021] (1) When the total number of passengers outside the outbound carriages is less than or equal to the original permitted passenger number; the corrected permitted passenger number remains the same as the original permitted passenger number;

[0022] (2) When the total number of passengers outside the outbound carriages is greater than the original permitted passenger number, the revised permitted passenger number is equal to the total number of passengers outside the outbound carriages; that is, the corrected permitted passenger number = the number of passengers greater than the original permitted passenger number outside the outbound carriages + the original permitted passenger number:

[0023] In implementation, the number of passengers greater than the original permitted passenger number outside the outbound carriages is added to the original permitted passenger number.

[0024] The number greater than the part is added to the original permitted passenger number to form a new corrected permitted passenger number, and is transmitted to the display control unit of the computer system at the next station; the display control unit of the computer at the next station displays the corrected permitted passenger number on the display screen;

[0025] The method for calculating the total number of passengers outside the outbound carriages includes the agreed time for calculating the total number of passengers outside the outbound carriages. At the agreed time (or node) for calculating the total number of passengers outside the outbound carriages, this node can be set at the closing time of the train at this station, or a period of time after the closing time. Here, the closing time of the train is used as the agreed time;

[0026] Specific implementation:

[0028] Step 2: The passenger flow counter outside the entering station carriage, the passenger flow counter outside the leaving station carriage, and the instantaneous passenger counter in the waiting carriage above start to record; the instantaneous passenger counter in the waiting carriage transmits the recorded instantaneous passengers in the waiting carriage to the server instruction unit or the on-vehicle computer;

[0029] Step 3: When the train arrives at the next station, the door sensor in the carriage transmits the information of the opened door to the passenger counter outside the entering station carriage and the passenger counter outside the leaving station carriage;

[0030] Step 4: The passenger flow counter outside the entering station carriage and the passenger flow counter outside the leaving station carriage end the recording.

[0031] Step 5: The passenger flow counters outside the entering and leaving stations upload the number of passengers outside the entering and leaving stations to the server instruction unit or the on-vehicle computer;

[0032] Or the passenger flow counters outside the entering and leaving stations upload the number of passengers outside the entering and leaving stations to the corrected passenger number calculation unit of the on-vehicle computer, and the corrected passenger number calculation unit obtains the total number of passengers outside the leaving station; the total number of passengers outside the leaving station = the total number of instantaneous passengers in the waiting carriage + the total number of passengers outside the leaving station - the total number of passengers outside the entering station; the corrected passenger number calculation unit uploads the total number of passengers outside the leaving station to the server instruction unit or the on-vehicle computer;

[0033] Step 6: The server instruction unit or the on-vehicle computer instruction unit obtains the total number of passengers outside the leaving station, that is, the number of passengers getting off at the next station, based on the total number of passengers entering the waiting carriage, the total number of passengers outside the leaving station, and the total number of instantaneous passengers in the waiting carriage above; that is, the total number of passengers outside the leaving station = the total number of instantaneous passengers in the waiting carriage + the total number of passengers outside the leaving station - the total number of passengers outside the entering station.

[0034] Step 7: The server instruction unit or the on-vehicle computer issues instructions to the gate control unit and the display control unit of the computer in the next station's boarding area:

[0035] (1) When the total number of passengers outside the leaving station is equal to or less than the number of passengers allowed to enter the boarding area, correct the number of passengers allowed to enter the boarding area = the original number of passengers allowed to enter the boarding area;

[0036] (2) When the total number of passengers outside the outbound carriage is greater than the number of passengers allowed to enter the boarding area, revise the number of passengers allowed to enter the boarding area = the total number of passengers outside the outbound carriage; that is, revise the number of passengers allowed to enter the boarding area = the number of passengers by which the total number of passengers outside the outbound carriage is greater than the original number of passengers allowed to enter the boarding area + the original number of passengers allowed to enter the boarding area.

[0037] In implementation, add the number of passengers by which the total number of passengers outside the outbound carriage is greater than the original number of passengers allowed to enter the boarding area to the original number of passengers allowed to enter the boarding area.

[0038] In step 8, the gate control unit and the display control unit of the computer in the next boarding area execute the server instruction unit or the instruction sent by the on-vehicle computer; and timely display the revised number of passengers allowed to enter the boarding area on the display screen.

[0046]

[0047] The database system for controlling the gates in the boarding area of the platform is characterized in that: the on-vehicle computer includes a storage unit, and the storage unit stores the vehicle operation table of this vehicle; that is, the table of the only database, as shown in Table 2;

[0048] Each on-vehicle computer has a table of the only database of this vehicle in the vehicle operation table, which is used to store the operation data of the on-vehicle computer of this vehicle or the instructions or data transmitted to the platform computer (address); each on-vehicle computer or platform computer is a subsystem of the entire system; thus constituting the database system of the vehicle platform gate control server.

[0049] For any (cn) vehicle on-vehicle computer, the vehicle operation table 1: abbreviated as vehicle operation table 1 (the following takes the A on-vehicle computer as an example; the vehicle operation tables of other on-vehicle computers of vehicles can be proved in the same way; and the vehicle operation tables 1 of all operating vehicle on-vehicle computers are stored in the database of the server for backup)

[0050] Table 2, Vehicle Operation Table:

[0051]

[0052] The database system for controlling the gates in the boarding area of the platform is characterized in that: the boarding area computer includes a communication unit, and the communication unit stores the IP address communication table of the boarding area computer or all vehicle computers. The communication table of the boarding area or all vehicles includes the IP address communication tables of the next boarding area, all boarding areas or all vehicles, which is used to transmit the instruction information to the corresponding boarding area computer IP address, the next boarding area computer IP address or the server IP address.

[0053] The boarding area IP address, the next boarding area IP address, the server IP address or the train IP address; as shown in Tables 1 and 2.

[0054] The database system for controlling the gates in the boarding area of the platform is characterized in that:

[0055] It includes the function of the server computing unit: converting the train timetable from the operation center into this train operation table and the platform operation table. The server needs to perform change operation modes on the original platform operation table, the original vehicle operation table, the original vehicle category table, the original platform category table, the original vehicle information table, and the original platform information table. This process is what we call the conversion mode from the train timetable to the platform operation table or the train operation table. And the modified new platform operation table, vehicle operation table, vehicle category table, platform category table, vehicle information table, and platform information table are stored in the database of the server or the storage units of the platform computer and the on-vehicle computer, as the platform operation table, vehicle operation table, vehicle category table, platform category table, vehicle information table, and platform information table that are valid for use on the same day.

[0056] (1) The first step is to register the IP addresses of the computers in the boarding areas of all platforms, as well as the IP addresses and numbers of all vehicles, and register the platform boarding area table and the vehicle table.

[0057] (2) The daily increase or decrease of vehicles in the train timetable of the operation center is transmitted to the server. The server then adds the corresponding vehicle numbers and IPs of the increased vehicles to the elements of the vehicles in operation in the operation table according to the operation table, or deletes the numbers or IP addresses of the decreased vehicles from the operation table and adds them to the elements of the waiting vehicles in the table.

[0058] (3) If a newly added operating vehicle changes from the waiting state in the table element to the operating state, or if a subtracted vehicle changes from the operating state to the waiting state.

[0059] (4) Each restricted carriage contains two boarding areas, A and B, as well as the computer numbers and IP addresses of the boarding area computers in the restricted carriage AB.

[0060] (5) The conversion of the daily train timetable of the operation center to the vehicle operation table or the platform operation table of the server is carried out before the daily train operation. If it is a real-time or anytime conversion, that is, when adding or subtracting trains, that random mode requires stopping the train operation. Then the train timetable is converted into the carriage operation table or the platform operation table.

[0061] (6) The times in the boarding area operation table and the vehicle operation table are kept in one-to-one correspondence with the train timetable: the predetermined numbers in the platform operation table and the vehicle operation table can refer to the predetermined numbers of the same boarding area, the same adjacent time, and adjacent vehicles.

[0062] The boarding area operation table and the vehicle operation table belong to the log. Each boarding area has the boarding area operation table for the current day, and each vehicle has the vehicle operation table for the current day. At the end of the day's operation, the boarding area operation table for the current day of each boarding area and the vehicle operation table for the current day of each vehicle are stored in the database as redundant, backup, or data collected when calculating the predetermined numbers;

[0063] (7) The vehicle category table, platform category table, vehicle information table, and platform information table stored in the database are mainly used for the server to convert the train timetable of the operation center into the train operation table and the platform operation table.

[0064] (8) The types in the train type table are divided into trains in operation, the numbers of the trains in operation, indicating that the vehicle is in operation, as well as waiting trains, including the train numbers if the train is in the waiting state, the IP address of the on-board computer of the train, and the train IP address of the waiting train.

[0065] (9) When the train is in the waiting state, fill in the waiting train in the waiting train operation table. If the train enters the operation state from the waiting state, change the waiting state in the table to the operation state.

[0066] (10) In the train type table, the types are divided into trains in operation, the numbers of the trains in operation, indicating that these vehicles are in operation, and waiting vehicles, including the train numbers. If this train is in the waiting state, there are also the IP addresses of the on-board computers of the trains, and the train IP addresses of the waiting trains.

[0067] (11) When the train is in the waiting state, fill in the waiting train in the waiting train operation table. If the train enters the operation state from the waiting state, change the waiting state in the table to the operation state.

[0068] (12) Similarly, the platform operation table is divided into the operation state and the waiting state.

[0069] (13) The vehicle information table includes the unique number of the vehicle, the IP address of the on-board computer of the vehicle, and whether the operation state of the vehicle is the running state or the waiting state. It is mainly used to transfer the vehicle from the train timetable back to the vehicle operation table.

[0070] (14) Similarly, the platform operation table also includes the above content.

[0071] (15) The original number of passengers in the train operation table refers to the total number of passengers in the restricted carriage before the train door opens at this station. The current number of passengers in the restricted carriage at the time of door closing is equal to the original total number of passengers plus the number of passengers who enter the restricted carriage from the train door opening time to the door closing time at this station.

[0072] (16) The reserved number of passengers is the number of passengers allowed to enter the next station's boarding area set by the server according to a certain rule.

[0073] (17) Before a certain vehicle enters operation, it must be registered in the table and then can enter operation. If it does not enter registration, it cannot enter operation. At the same time, when changing from the operation state to the standby state, that is, changing the vehicle number from the operating state to the waiting state.

[0074] (18) Each vehicle has a unique number, a unique card number, and the IP address of the on-board computer. When the vehicle enters the operation or waiting state, the card number should be added to the computer system. And connect the IP address of this on-board computer to the entire system.

[0075] (19) When exiting the operation or waiting state, remove the card number from the entire system, and also stop connecting the IP address of the on-board computer from the entire system.

[0076] (20) Before the vehicle can be operated, the card number must be registered in the entire system. Only after successful registration can it enter the operation or waiting state.

[0077] (21) Vehicles that have not been registered or have failed to be registered cannot enter the operation or waiting status.

[0078] (22) When a train is added, the server refers to the scheduled number of vehicles stopping at the next adjacent station at the same platform at the same time as the next station scheduled number of the vehicle.

[0079] (23) or formulate the reservation number for each train in the boarding area according to the train operation timetable transmitted by the operation center;

[0089] (Platform) Boarding Area Information Table

[0090]

[0091] The general idea of the database system for controlling the gates in the boarding area of the platform is as follows: (1) The control center transmits the train schedule to the server computing unit every day. The train schedule includes operation time, namely the tabulation date (or including the week), train number, train number operation sequence, name of the platform where the train stops (during operation), name of the originating station, originating time, stopping time, name of the reversing station, reversing time, name of the terminal station, terminal time, etc. (2) The server computing unit converts the train operation schedule transmitted by the control center into an operation table for the boarding area and a vehicle operation table, which are used by the server instruction unit, the computer in the boarding area, and the on-vehicle computer. The operation table for the boarding area and the vehicle operation table divide each train number into corresponding front and rear restricted carriage numbers A and B, and divide each platform name into numbers for the front and rear restricted carriage boarding areas A and B. The rest of the operation time (or including the week), train number operation sequence, name of the originating station, originating time, stopping time, name of the reversing station, reversing time, name of the terminal station, terminal time, etc. are changed correspondingly one by one.

[0092] Computer program: Step 1, the door opens, and the door sensor transmits the door opening information to the passenger flow counters for entering and exiting the restricted carriage. The passenger flow counters for entering and exiting the restricted carriage start recording. Step 2, the door closes, and the door sensor transmits the door closing information to the passenger flow counters for entering and exiting the restricted carriage. The passenger flow counters for entering and exiting the restricted carriage stop recording the number of passengers entering and exiting the carriage, and transmit the number of passengers entering and exiting the restricted carriage from the door opening time to the door closing time to the total passenger number calculation unit in the instruction unit. This unit calculates the total number of passengers entering the restricted carriage. Step 3, the instruction unit uploads the total number of passengers entering the restricted carriage to the server. Step 4, the server retrieves the original total number of passengers at this station from the vehicle operation table in the database, adds the original total number of passengers at this station to the total number of passengers entering the restricted carriage at this station to obtain the current total number of passengers in the restricted carriage at this station. The server uses the gate instruction algorithm to issue a gate control instruction to the gate control unit of the next station's boarding area, and uses the instruction algorithm for the number of passengers allowed to enter the boarding area to issue an instruction for the number of passengers allowed to enter the boarding area to the display control unit of the computer in the next station's boarding area. Step 5, the server transmits the gate control instruction and the instruction for the number of passengers allowed to enter to the gate control unit and the display control unit of the computer in the next station's boarding area.

[0093] Specific implementation:

[0094] (3) The server computing unit stores the vehicle operation table in the database;

[0095] The server computing unit transmits and stores the vehicle operation table to the on-vehicle computer as a redundant system for the on-vehicle computer to use; the operation table for the boarding area is transmitted to the computer in the boarding area for the computer in the boarding area to use;

[0096] Each boarding area computer is divided into an instruction system and an execution system. The instruction system includes a door sensor, a counter for restricting the number of passengers entering the carriage, a counter for restricting the number of passengers leaving the carriage, and a unit for calculating the total number of passengers.

[0097] The execution system includes a gate control unit and a display control unit for the next boarding area computer.

[0098] The on-vehicle computer belongs to the instruction system and includes a door sensor, a counter for restricting the entering passenger flow, a counter for restricting the number of passengers leaving the carriage, and a unit for calculating the total number of passengers.

[0099] The instruction system of the boarding area computer is equipped with a door sensor, a counter for restricting the number of passengers entering the carriage, and a counter for restricting the number of passengers leaving the carriage in the boarding area;

[0100] The door sensor is linked to the counter for restricting the number of passengers entering the carriage and the counter for restricting the number of passengers leaving the carriage;

[0101] When the train enters the platform, the door sensor transmits the information that the door is opened to the counter for restricting the number of passengers entering the carriage, and the counter for restricting the number of passengers entering the carriage starts to record the number of passengers entering the restricted carriage. At the same time, the door sensor transmits the information that the door is opened to the counter for restricting the number of passengers leaving the carriage, and the counter for restricting the number of passengers leaving the carriage starts to record the number of passengers leaving the restricted carriage;

[0102] When the train leaves the platform, the door sensor transmits the information that the train door is closed to the counter for restricting the number of passengers entering the carriage, and the counter for restricting the number of passengers entering the carriage stops recording the number of passengers; at the same time, the door sensor transmits the information that the door is closed to the counter for restricting the number of passengers leaving the carriage, and the counter for restricting the number of passengers leaving the carriage stops recording the number of passengers leaving the restricted carriage.

[0103] At the same time, the counter for restricting the number of passengers entering the carriage transmits the number of passengers entering the restricted carriage during the period from the door opening to the train door closing to the server; the counter for restricting the number of passengers leaving the carriage transmits the number of passengers leaving the restricted carriage during the period from the door opening to the train door closing to the server;

[0104] Or the counter for restricting the number of passengers entering the carriage transmits the number of passengers entering the restricted carriage during the period from the door opening to the train door closing to the unit for calculating the total number of passengers; the unit for calculating the total number of passengers transmits the number of passengers leaving the restricted carriage during the period from the door opening to the train door closing to the unit for calculating the total number of passengers; the unit for calculating the total number of passengers obtains the total number of passengers entering the restricted carriage and then transmits the total number of passengers entering the restricted carriage to the server.

[0105] The function of the total passenger count unit is to receive the number of passengers entering the restricted carriage from the restricted carriage entrance counter from door opening to door closing, and the number of passengers leaving the restricted carriage from the restricted carriage exit counter from door opening to door closing; calculate the total number of passengers entering the restricted carriage, and the total number of passengers entering the restricted carriage from door opening to door closing = the number of passengers entering the restricted carriage from door opening to door closing - the number of passengers leaving the restricted carriage from door opening to door closing;

[0106] The total number of passengers entering the restricted carriage from door opening to door closing is simply referred to as the total number of passengers entering the restricted carriage

[0107] (4) The server calculation unit stores the vehicle operation table in the server database or the storage unit of the on-vehicle computer, and the riding area operation table in the server database or the storage unit of the riding area computer for storage as an operation log file or backup data; the database stores the train operation table of each train and the directory table of the train operation tables of all trains, and includes the riding area operation table of each riding area of each platform and the directory of the riding area operation tables of all riding areas for retrieval, query, and the location of the riding area operation table of the riding area in the database.

[0108] (5) The server instruction unit, in-vehicle computer, and boarding area computer are provided with computer programs with instruction algorithms; used to calculate and send opening and closing commands for the gate units of the boarding area computers at the next stop. (6) The functions of the server and the in-vehicle computer and boarding area computer acting as clients are as follows: (1) The server (obtains the total number of passengers entering the waiting carriage from the opening to the closing of the train door; the total number of passengers entering the waiting carriage from the opening to the closing of the train door = the number of passengers entering the waiting carriage from the opening to the closing of the train door - the number of passengers leaving the waiting carriage from the opening to the closing of the train door; and obtains the total number of existing passengers when the train door is closed, the total number of existing passengers when the train door is closed = the original number of passengers in the carriage before the train door opens + the total number of passengers entering the waiting carriage from the opening to the closing of the train door;) calculates and sends a command to control the gate for entering the boarding area to the gate control unit of the boarding area computer at the next stop based on the total number of passengers provided by the terminal device counter; (2) calculates and sends a command to display the number of passengers allowed to enter the boarding area to the display unit of the boarding area computer at the next stop; (3) The in-vehicle computer calculates and sends a command to display the number of passengers allowed to enter the boarding area to the display unit of the boarding area computer at the next stop for correction based on the number of passengers provided by the counters outside the in-vehicle compartments for entry and exit. (The function of the gate control unit of the boarding area computer at the next stop is to execute the gate control command sent by the server (or instruction computer) to open and close the gates for entering the boarding area at the next stop. When the number of passengers entering the boarding area reaches the number of passengers allowed to enter the boarding area, the gates for entering the boarding area are closed; the function of the display control unit of the boarding area computer at the next stop is to execute the display control command sent by the server (instruction computer) to display the number of passengers allowed to enter the boarding area and display the number of passengers allowed to enter the boarding area on the display screen; achieving the purpose of controlling the number of passengers in the carriage with restricted entry to the maximum number of passengers; ) achieving the purpose of controlling the number of passengers outside the station compartments within the limit value.

[0109] Meanwhile, as a supplement to the function of the instruction computer unit sent by the server as the execution computer for the next boarding area, it can also be completed by the instruction unit of the boarding area computer in the boarding section or the instruction unit of the in-vehicle computer, which is an alternative mode.

[0110] The specific operation is that the operation table of the boarding area, gate instruction algorithm, and display screen instruction algorithm are stored in the boarding area computer. Or the vehicle operation table, gate instruction algorithm, and display screen instruction algorithm are stored in the in-vehicle computer;

[0111] Then, when the boarding area (in-vehicle) computer obtains the total number of passengers from the train door opening time to the train door closing time sent by the counter unit of the boarding area computer, it sends a command to the next computer according to the gate instruction algorithm or the display screen instruction algorithm.

[0112] This is a supplement to the instruction unit of the server or a redundant mode.

[0119] Or the in-out passenger flow counters of the restricted carriage transmit the number of passengers entering and leaving the restricted carriage from the time when the train door is opened to closed to the unit for calculating the total number of passengers entering the restricted carriage, and the unit for calculating the total number of passengers entering the restricted carriage obtains the total number of passengers entering the restricted carriage; Transmit the total number of passengers entering the restricted carriage to the server;

[0120] The server calculates the total number of existing passengers when the train door closes. The total number of existing passengers = the total number of original passengers in the carriage before the train door opens + the total number of passengers entering the waiting carriage from the opening to the closing of the train door. According to the gate instruction algorithm, the display screen instruction algorithm, and the total number of existing passengers, the server sends the gate instruction and the display screen instruction for the next station (the second station) to the execution system of the computer in Area A of the next station. Step 5 is at the first departure station. The server stores the total number of existing passengers of the vehicle at the closing time (cn) in the boarding area of this station (the first departure station) into the element of the total number of existing passengers of the vehicle in the boarding area operation table of the database, and stores it into the element of the total number of original passengers of the next station (the second station) in the boarding area operation table. Step 6 is at the second station. The execution system of the computer in Area A of the second station executes the gate instruction and the display screen instruction sent by the server.

[0121] Step 7 is that (at the second station) the passenger flow counter for entering and exiting the restricted carriage in the instruction system of the computer in Area A of the second station transfers the number of passengers entering and exiting the restricted carriage from the opening to the closing of the train door to the server, and the server calculates the total number of passengers entering the restricted carriage.

[0122] The server calculates the total number of existing passengers when the train door closes. According to the gate instruction algorithm, the display screen instruction algorithm, and the total number of existing passengers, the server sends the gate instruction and the display screen instruction for the next station (the third station) to the execution system of the computer in Area A of the next station. Step 8 is at (the second station). The server stores the total number of existing passengers of the vehicle at the closing time (cn) in the boarding area of this station (the second station) into the element of the total number of existing passengers of the vehicle in the boarding area operation table of the database, and stores it into the element of the total number of original passengers of the next station (the third station) in the boarding area operation table. Step 9 is at the third station. The execution system of the computer in Area A of the third station executes the gate instruction and the display screen instruction sent by the server.

The on-vehicle computer or server of the waiting carriage A of the vehicle stores the total number of passengers of the vehicle at the agreed closing time of the boarding area of this station (the (zn)-th station) into the element of the total number of passengers of this vehicle in the row of this station platform (the (zn)-th station) of the vehicle operation table; and transmits or stores the total number of passengers of the vehicle parked in the boarding area of this station to the element of the total number of passengers of the vehicle at the previous station (the (zn)-th station) in the row of the previous station (the (zn)-th station) of the vehicle operation table of the waiting carriage A of the vehicle at the next station (the (zn + 1)-th station).15 is the instruction from the on-vehicle computer of vehicle A at platform (zn) to the computer of the boarding area (zn + 1)A to open or close the gate to enter the boarding area; the display screen shows the number of passengers allowed to enter; or the display control unit of the computer in the boarding area (zn + 1)A executes the correction of the number of passengers allowed to enter sent by the display control unit of the on-vehicle computer of vehicle A at platform (zn); 16 is that when vehicle (cn) stops at station (zn + 1), the gate control unit or server of the on-vehicle computer of vehicle A (cn) sends the instruction to open or close the gate to enter the boarding area at the next station (the (zn + 2)-nd station) to the computer of the boarding area at the next station (the (zn + 2)-nd station) according to the instruction algorithm and the total number of passengers obtained from the passenger flow counter; 17 is that when traveling from station (zn + 1) to station (zn + 2), the correction unit of the number of passengers allowed to enter of the on-vehicle computer of vehicle A (cn) or the server calculates the corrected number of passengers allowed to enter according to the total number of passengers in the outer carriage getting off at the station (i.e., the total number of passengers getting off at the next station) obtained from the passenger flow counter and the correction algorithm of the number of passengers allowed to enter, and sends the corrected number of passengers allowed to enter to the computer of the boarding area at the next station (the (zn + 2)-nd station); 18 is the agreed closing time of vehicle (cn) at station (zn + 1), and the on-vehicle computer or server of the waiting carriage A of vehicle (cn) stores the total number of passengers of vehicle (cn) at the agreed closing time in the boarding area of this station (the (zn + 1)-st station) into the element of the total number of passengers of this vehicle in the row of this station (the (zn + 1)-st station) in the vehicle operation table; and transmits or stores the total number of passengers of vehicle (cn) parked in the boarding area of this station to the element of the total number of passengers of the previous station (the (zn + 1)-st station) of this vehicle in the row of the previous station (the (zn + 1)-st station) of vehicle (cn) in the waiting carriage A of the next station (the (zn + 2)-nd station) in the vehicle operation table; 19 is the gate control unit of the on-vehicle computer of vehicle A (cn) at the return (or terminal) station, which clears the total number of passengers according to the passenger counter; 20 is the return operation procedure (or terminal operation), or ends the operation; 21 is to enter the return computer program or end the operation. After ending the operation of the day, all computers in the boarding areas upload the boarding area operation tables of their respective boarding areas on that day to the server, so that the server can provide the total number of passengers entering the waiting carriage in this boarding area according to the operation sequence and stop time when formulating the predetermined number of each vehicle in the next cycle (such as a 4-week cycle in this article); 22 is the platform of the first departure station, 23 is the second platform, 24 is the platform of any station (zn), 25 is the platform of (zn + 1), 26 is the return (or terminal) station.

[0136] Figure 4It is the main flowchart of the computer program for the gate instruction unit algorithm and the display screen instruction algorithm: that is, in the database system for controlling the gates in the boarding area, the server instruction unit at any (zn) platform or the gate instruction unit and the display screen instruction unit of the computer in the boarding area (or on the vehicle) send gate instructions and display screen instructions to the gate control unit and the display screen control unit of the computer in the next boarding area. 1. The train entry and exit platform sensors at the zn platform limit the carriage door opening time. 2. The inbound restricted carriage passenger flow counter at the (zn) platform starts counting the number of people. 3.

Select according to the gate instruction algorithm and the display screen instruction algorithm. 7. For the (cn) restricted carriage parked at this zn platform, when the door closing agreed time arrives and the total number of passengers in the existing carriages of this (cn) is equal to or greater than the limit number of the (cn) restricted carriage + the predetermined number, send a gate closing instruction to the gate control unit of the computer in the next boarding area. 8. For the (cn) restricted carriage parked at this zn platform, when the door closing agreed time arrives and the total number of passengers in the existing carriages of this (cn) is equal to or less than the limit number of passengers in the (cn) restricted carriage + the predetermined number, send a gate opening instruction to the gate control unit of the computer in the next boarding area; and send a display instruction for the number of passengers allowed to enter to the display screen unit of the computer in the next boarding area. The number of passengers allowed to enter = the limit number of passengers + the predetermined number - the total number of passengers at this station. 9. The gate control unit or the display screen unit of the computer at the continuous next (zn + 1) platform executes. 10. The server instruction unit or the vehicle computer instruction system stores the total number of existing passengers in the restricted carriage in this boarding area into the element of the total number of existing passengers in the current row of the vehicle operation table or the vehicle operation table in this boarding area for this vehicle, and stores or transmits the total number of existing passengers to the element of the original number of passengers of this vehicle in the vehicle operation table or the vehicle operation table in the next boarding area for this vehicle, as the base for calculating the total number of existing passengers of this vehicle at the next station when the door closing time of this vehicle at the next boarding area. The vehicle includes each operating vehicle; see Table 1, the vehicle operation table in the boarding area; Table 2, the vehicle operation table.

[0137] Figure 5 It is the main flowchart of the computer program for the subsystem (correction algorithm for the number of passengers allowed to enter) of the control computer that corrects the number of passengers allowed to enter for the computer in the next (zn + 1) boarding area by the server instruction unit at any (zn) platform or the on-vehicle computer of the (cn) carriage in the database system for controlling the gates in the boarding area.

[0138] 1. At the agreed closing time of the doors of the waiting carriage at the zn platform, activate the static passenger flow counter in the waiting carriage of the (cn) carriage, the passenger flow counter for the area outside the entrance to the boarding area of the waiting carriage of the (cn) carriage, and the passenger flow counter for the area outside the exit from the boarding area of the waiting carriage of the (cn) carriage, or activate them after a certain agreed time, say 10 seconds, after the agreed closing time of the waiting carriage. 2. The static passenger flow counter in the waiting carriage of the (cn) carriage calculates the instantaneous number of passengers in the waiting carriage. 3. The passenger flow counter for the area outside the entrance to the boarding area of the waiting carriage of the (cn) carriage starts counting. 4. The passenger flow counter for the area outside the exit from the boarding area of the waiting carriage of the (cn) carriage starts counting. 5. The agreed time for the doors of the waiting carriage at the zn+1 platform to open. 6. The agreed time for the doors of the waiting carriage at the zn+1 platform to open. 7. The passenger flow counter for the area outside the entrance to the boarding area of the waiting carriage at the (zn+1) platform stops counting. 8. The passenger flow counter for the area outside the exit from the boarding area of the waiting carriage at the zn+1 platform stops counting. 9. The on-vehicle computer of the (cn) carriage calculates that the number of alighting passengers = the number of passengers in the waiting carriage calculated by the static passenger flow counter + the real-time number of passengers obtained from the passenger flow counter for the area outside the exit - the real-time number of passengers obtained from the passenger flow counter for the area outside the entrance. Steps 1-8 are used to calculate the number of passengers in the area outside the exit. Among them, for calculating the number of passengers in the area outside the exit, steps 2, 4, 6, and 8 can also be omitted.

[0139] Example 4: Directly use the in-station and out-station sensors of the train at the zn platform to activate the passenger flow counter for the area outside the exit of the waiting carriage of the (cn) carriage at the agreed closing time, and use the in-station and out-station sensors of the train at the zn+1 platform to deactivate the passenger flow counter for the area outside the exit of the waiting carriage of the (cn) carriage at the agreed opening time. The number of passengers recorded by the passenger flow counter for the area outside the exit during this period is transmitted by the passenger flow counter for the area outside the exit to the server, on-vehicle computer, or boarding area computer. The server, on-vehicle computer, or boarding area computer calculates the corrected allowable number of entering passengers based on the corrected allowable number of entering passengers algorithm and the number of passengers in the area outside the exit, and then sends the corrected allowable number of entering passengers to the display unit of the next-stop boarding area computer, and the display unit of the next-stop boarding area computer executes the corrected allowable number of entering passengers sent by the server, on-vehicle computer, or boarding area computer.

[0140] 10 is the selection. 11 is the agreed time for the (cn) carriage to open its doors when departing from the zn platform to the (zn + 1) platform. When the total number of passengers outside the (cn) carriage at this station is equal to or less than the predetermined number of the (cn) carriage, an instruction to maintain the display of the permitted number of passengers entering is sent to the display unit of the computer in the next station's boarding area; 12 is the agreed time for the (cn) carriage to open its doors when departing from the zn platform to the (zn + 1) platform. When the total number of passengers outside the (cz) carriage at this station is greater than the predetermined number of passengers in the (cn) carriage; calculate the value greater than the predetermined value and send an instruction to the display unit of the computer in the next station's boarding area to display the predetermined number + the value greater than the predetermined value; 13 is the display unit of the computer of the consecutive next station's (zn + 1) platform, 14 is the display screen (or including the LAD display screen) for entering the boarding area of the (zn + 1) platform; 15 is the end. Regarding the second calibration program: When the on-vehicle computer receives the door-closing time node, when the on-vehicle computer sends the display of the predetermined number to the computer in the next station's boarding area, the second calibration program is naturally started; that is, from the door-closing time of the carriage to the door-opening time of the next station, this time period is divided into several agreed time nodes. The first time node can be set to 10 seconds, and then the recording of passengers entering the waiting carriage from outside the carriage starts. When the number of passengers entering the waiting carriage from outside the carriage reaches the number of passengers permitted to enter the boarding area for the first time or the predetermined number, it is a time node. After this time node, the passengers entering the waiting carriage can be regarded as the number of passengers getting off at the next station exceeding the number of passengers permitted to enter the boarding area for the first time or the predetermined number. We transmit the excess number of passengers to the display unit of the computer in the next station's boarding area and use this part of the passengers as a correction to the number of passengers permitted to enter for the first time; that is, add this part of the number of passengers to the number of passengers permitted to enter for the first time as the number of passengers permitted to enter for the second time; and display it on the display screen so that the passengers on the platform can enter the boarding area according to the revised number of passengers permitted to enter for the second time. Then, correct the previous boarding area every one time period. This time period can be set to 10 seconds or 5 seconds, and then transmit the newly obtained number of passengers permitted to enter to the display unit of the computer in the next station's boarding area. To achieve timely replenishment of the empty spaces in the carriage; this is the logical relationship behind this program;
