The storage unit stores: table 9, ride zone in-restricted carriage passenger count table of the ride zone; table 10 passenger area summary of entrance limit passenger number table index: table 11, vehicle "enter limit carriage passenger number table"; table 12. Vehicle summary of entrance limit car passenger number table index: when each passenger counting unit stores the number of passengers entering the restricted compartment from the time when the door is opened to the time when the door is closed into the passenger compartment computer or the vehicle-mounted computer stores the current passenger list of the restricted compartment in the passenger compartment, the passenger list of the restricted compartment in the vehicle compartment in the current day in a table 9,

or after the operation time of each day is over, the riding area computer or the vehicle-mounted computer reports the daily log to the server as redundancy and backup, or as big data for calculating the predetermined number.

In the prior art, a passenger flow counter is installed at a position corresponding to a door of a restricted carriage, but in a computer program of the prior art, the total number of passengers entering the restricted carriage is recorded by a passenger counting unit, and the total number of the passengers entering the restricted carriage cannot be transmitted to a gate instruction unit in real time; the total number of passengers entering a restricted compartment is recorded from the train arrival time to the train departure time and is transmitted to a gate command unit at a time node when the train leaves the station, the function of the gate command unit in the prior art is to obtain the number of allowed passengers according to the number of the passengers existing at the train departure time node and a preset number, command and control a next station to enter a gate control unit, and control the number of passengers entering a riding area from the next station to be within the number of the allowed passengers.

The technical problems or defects which are not solved by the prior art are as follows: the time node that prior art calculated next station gate switch instruction is the time node that this station train leaves the platform, and gate control instruction is not to this station entering gate control unit, when the passenger number in this station restriction carriage surpassed limit passenger number for the first time, can't obtain timely control, for example: when the number of passengers in the limited compartment exceeds the limit number of passengers for the first time, when a train does not leave the station and a compartment door is not closed, the number of passengers in the limited compartment is suddenly increased at a transfer station with large passenger flow, because the number of passengers entering the limited compartment cannot be recorded in real time, namely the passenger flow counter does not upload the number of passengers to the gate instruction unit in real time, the gate instruction unit cannot immediately control the number of passengers entering the station in real time when the number of passengers exceeds the limit number of passengers for the first time, so that many passengers continue to enter the limited compartment after the number of passengers in the limited compartment exceeds the limit number of passengers for the first time, and if the number of passengers exceeds the rated number of 50 persons, the technical defects of crowding and blocking of the number of passengers in the limited compartment are caused, and the departure time of the train is delayed.

Another prior art is that the gate for entering and exiting the riding area is provided with a counter to count the number of passengers entering the riding area, and the number of passengers entering the limited compartment is not accurately counted, if the number of passengers entering the riding area does not get on the bus or passengers getting off the bus do not immediately exit the riding area, the number of passengers entering the limited compartment is not accurately counted and errors are caused, so the number of passengers entering the limited compartment is not accurately counted in the prior art, and the purpose of accurately controlling the passengers entering the riding area at the next station is not achieved.

According to the technology, the video passenger flow counter is arranged on the platform or the carriage at the position corresponding to the door of the limited carriage, so that the number of passengers entering the limited carriage can be counted very accurately, and the purpose of accurately controlling the number of passengers entering a next riding area is achieved; further comprising a flexibility limit number of passengers, said flexibility limit number of passengers = limit number of passengers + predetermined number, flexibility limit number of passengers one variable.

The prior art has the defects that (1) when the number of passengers entering a riding area of one platform reaches the limit, a gate for entering the riding area of the next station is closed, the riding space of the passengers getting off the next station is reserved, the passengers can not get in the next station to fill in the riding space in real time, and the utilization rate of the outside-station compartment is wasted. (2) The limit passenger number set by the counter arranged on the gate of the riding area is not related to the train schedule, so that the number of passengers getting on the train on a large traffic road, a small traffic road and different platforms cannot be accurately judged, and the prior art is difficult to use due to the fact that the number of passengers getting on the train is 2 points. The method (1) adopts a predetermined number algorithm, wherein the predetermined number is changed from the constant limiting the number of passengers in the prior art into the variable quantity according to different platform passenger areas; namely, changing the limit passenger number from a constant value to a variable value; the flexible limit passenger number is adopted, and the utilization rate of the outside-station carriage rate is improved; (2) The server computing unit converts the train schedule into a next station gate instruction of the riding area or a next station gate instruction of the vehicle in real time, the number of passengers entering the riding area can be determined in real time according to increase and decrease of the train, and confusion of the passengers due to unclear large and small traffic routes due to increase and decrease of the train is prevented. (3) Because the average number of passengers getting on and off the train in different platform riding areas is different, the number of passengers in a transfer station is large, the number of passengers in a non-transfer station is small, and in order to accurately release the number of passengers getting on the next station in advance, the control unit of the next station riding area can release the passengers according to the average number of the passengers during the running process of the train entering the next station riding area from one platform, so as to accurately control the number of the passengers getting on the train in the riding area from different platforms, a method for releasing the average number of the passengers getting on and off the train, namely a preset number algorithm, is adopted, thereby reducing the waste of the utilization rate of the off-station compartment caused by a large number of passengers getting on the train due to a large number of passengers getting off the train, and the congestion of the riding area caused by a large number of passengers getting on the train due to a small number of passengers getting off the train, so the preset number algorithm is provided:

the relation between the server and the control center comprises a connection mode and a non-connection mode:

(1) Connection mode: namely, server connection control center mode: the method has the advantages that the control center firstly determines the number of the newly added vehicle large traffic routes to the server in real time, and the calculation unit of the server can correct the next station gate instruction of the riding area or the next station gate instruction of the vehicle in real time. The connection mode has the advantage that the large and small routes of the train can be distinguished.

Namely, the server is connected with the control center, and the control center transmits the train schedule to the server mode;

the control center transmits a real-time train schedule to the server every day, the server compares the real-time train schedule with a next station gate instruction of a riding area or a next station gate instruction of a vehicle according to the real-time train schedule conversion, and if the real-time train schedule conversion is changed, the server correspondingly adjusts the next station gate instruction of the riding area or the next station gate instruction of the vehicle in real time; or the control center sends out a command of changing the train schedule, and the server correspondingly adjusts the next station gate command of the riding area or the next station gate command of the vehicle in real time;

(2) Non-connected mode, i.e. server not connected control center mode: the control center does not transmit the real-time train schedule to the server, and if the real-time train schedule is changed, the server correspondingly adjusts a next station gate instruction of the riding area or a next station gate instruction of the train in real time; or the control center sends out a command of changing the train schedule, and the server correspondingly adjusts the next station gate command of the riding area or the next station gate command of the vehicle in real time;

the connection mode or the non-connection mode is that the server calculates the average number of the limited carriages according to the big data in the general table of passengers in the limited carriages as a preset number to make the next station gate instruction of the riding area,

the temporary preset number of the new vehicle is determined by taking the preset number of the adjacent vehicles in the next station gate instruction of the riding area as a reference value, and vice versa,

function 1 with respect to the server computing unit: calculating the predetermined number: :

herein, it is tentatively set that every weekend (i.e., 24 sunday) calculates a predetermined number of time nodes for the server calculation unit; the statistical time period of the general table for limiting the number of passengers in the compartment is that Monday to seventy week are a statistical unit; calculating once per week, and sequentially replacing the old 'general table of number of passengers in limited compartment'; the predetermined number is the average number of passengers in the limited compartment every 3 weeks as a new predetermined number;

taking a total table of the number of passengers in the limited compartment in the riding area as an example, the server computing unit computes that the number of the riding area of 1,8A, the number of the vehicles of 6A and the arrival sequence of the vehicles are 56 in the week, the time from the vehicles to the station is 8 points 00 minutes, and the traffic number is a preset number of large traffic numbers;

the server computing unit searches a ' further restricted carriage passenger number table ' with the table index number being the number of 1,8A passenger areas in week from a ' total table of the number of passengers in the further restricted carriage ' at 24 points of sunday, further searches the ' 6A vehicle number, the arrival sequence of the vehicles is 56, the time from the vehicles to the station platform is 8 points 00 minutes, and the traffic number is ' the number of passengers in the further restricted carriage ' with a large traffic number; meanwhile, inquiring a 'counting table of passengers in restricted carriage' with the serial number of 18A riding areas for 3 weeks; selecting "limited car passenger number" for 3 consecutive weeks resulting in a new predetermined number, the new predetermined number =3 consecutive weeks plus/minus 3;

the server calculation unit adds the new preset number into a next station gate instruction of a riding area or a next station gate instruction of a vehicle to replace the old preset number; similarly, calculating new preset numbers of all riding area numbers, all vehicle numbers, arrival sequence, vehicle arrival time to platform and traffic route numbers; adding the new preset number into a gate instruction summary table of the next station of the riding area or a gate instruction summary table of the next station of the vehicle, and replacing the old preset number; the calculation of the new predetermined number is completed.

For example, the schedule of the passengers in the limited carriages is prepared in a cycle of Monday to seventy week, the schedule of the passengers in the limited carriages in each cycle is arranged in an ID week sequence number from the beginning of operation to the end of operation, and the average number of the passengers (several weeks) in the limited carriages of each ID vehicle in the ID riding area and the ID week sequence number (parking sequence number and arrival time) is used as the preset number of the ID vehicle in the ID riding area and the ID week sequence number (parking sequence number and arrival time).

The server computing unit counts the average number of the passengers in the ID vehicle in the limited compartment as the preset number of the ID vehicle according to the big data in the general list of the passengers in the limited compartment, the temporary preset number of the temporarily added vehicle is determined by the approaching time and the preset number of the ID vehicle with the same traffic number (big traffic number and small traffic number) as a reference value, and vice versa; the preset number is relatively stable and is corrected once in 30 days, and the temporary preset number of the temporary vehicle number can be corrected in real time;

the number of passengers getting on each day of each unit from the beginning of the operation to the end of the operation is the number of unique marked days of the number of passengers getting on each ID vehicle in the ID riding area from the stopping time of the ID vehicle in the ID riding area.

For example, the average number of the vehicles entering the restricted cars at the 12A riding area number is 20 according to the big data of 8 o' clock on monday in the passenger general table of the entering restricted cars, the predetermined number of the 6A vehicle number at the 12A riding area number at the time in the next riding area gate instruction is set to be 20, and the predetermined number of the uniquely marked vehicles at the uniquely marked platform riding area is set as the number of the uniquely marked vehicles on the uniquely marked platform riding area, wherein the number of the uniquely marked days of the week (day of the week) of the unique mark train at the parking time of the uniquely marked platform riding area is from the beginning to the end of the operation, and the number of the uniquely marked passengers on the uniquely marked days of the week (day of the week) of the unique mark train at the parking time of the uniquely marked platform riding area.

The provisional predetermined number of the newly added vehicle is determined by the predetermined number of the oncoming vehicles in the next station gate instruction in the riding area as the reference value, and vice versa for the reduction of the vehicle.

For example, a vehicle number at 6A is counted as a large traffic number according to 8-point big data on monday in the entrance limit car passenger table, the average number of the traffic numbers entering the limit car at 12A is 20 persons, and the predetermined number of the vehicle number at 6A at the time in the normal riding area next stop gate instruction is made to be 20 persons at 12A riding area number.

On monday 8 point 1, a predetermined number of newly-added vehicles is referenced by a predetermined number of 20 persons of neighboring vehicles in the next station gate command in the riding area to determine that the predetermined number of the vehicle serial number is 20 persons, and vice versa for decreasing the vehicles.

If the newly added vehicle is a large traffic route number and is at 8: 01, selecting the preset number of 20 persons of 6A vehicle numbers of adjacent vehicles with the same traffic route number between 8: 00 and 8: 02 as a reference value to determine that the temporary preset number of the newly added vehicle is 20 persons, meanwhile, the newly added vehicle number is a 7A vehicle, the original vehicle number is changed from the 7A vehicle number to an 8A vehicle number, the other original vehicle numbers are corrected in a natural sequence, and vice versa,

the method mainly comprises the steps that a control center firstly determines a newly-added vehicle large traffic route number to be sent to a server, and a non-connection mode does not timely send the determined newly-added vehicle large traffic route number to the server in the control center, so that passengers are easy to get in disorder. The connection mode has the advantage that the large and small traffic routes of the train can be distinguished. The disadvantage of the non-connection mode is that the large and small routes of the train cannot be distinguished.
