Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a passenger count measuring device that measures the number of passengers getting on and off a train at each station.

(Prior art) Investigating the number of passengers on a train is to check whether the number of trains running is appropriate for the number of passengers, that is, whether the train is full, there are many standing seats, and passenger service is degraded. On the other hand, we investigate whether there is a problem in terms of profitability due to the train being deserted and there are many empty seats, and we constantly strive to serve passengers and increase the number of passengers. This is very important in that it allows us to obtain data that can be investigated accordingly.

Traditionally, to survey passengers getting on and off at each station, multiple researchers boarded each car from the starting station and counted and recorded the number of passengers in each car each time the train departed from the station. at each station until the final station.

(Problem to be solved by the invention) Conventionally, as mentioned above, in order to investigate the number of passengers on a train, multiple investigators board the train and count the passengers one by one. Surveys are conducted continuously for one week each season, requiring a total of nearly 1,000 surveyors, which requires a large amount of money, effort, and time. The problem is that they can only conduct surveys, and even if they try to obtain more accurate data, there are limits in terms of securing survey personnel and costs, and they cannot increase the number of data.

The present invention has been made in view of the above, and an object of the present invention is to provide a passenger count measuring device that automatically and easily measures the number of passengers getting on and off at each boarding and alighting location.

A relay 61 that operates with the rectified voltage from this rectifier 61a
b, so that when the train 3 is running, a running detection signal is supplied from the running detection section 61 to the master station 4.

Next, the operation of the passenger count measuring device configured as described above will be explained with reference to the flowcharts shown in FIGS. 3 and 4.

When the train 3 stops at the platform 1 and the door 31 on the platform side opens, the door sensor 8 turns from on to off, and this signal is input from the door sensor 8 to the microprocessor 51 of the slave station 5 via the digital interface 54. . Then, when the passenger passes in front of the first and second sensors 91 and 92 provided in the boarding and alighting passage, the detection signals from the first and second sensors 91 and 92 change from OFF to ON. Signals are input from the first and second sensors 91 and 92 to the microprocessor 51 of the slave station 5 via the digital interface 54.

As described above, when the signals from the door sensor 8 and the first and second sensors 91 and 92 are input to the slave station 5, the slave station 5 receives the signals as shown in FIGS. 3(a) and 3(b). Execute program processing. Note that this processing includes the cyclic processing shown in FIG. 3(a) and the interrupt processing shown in FIG. When the buffer in the serial/parallel converter 56 becomes full when transmitting data is received, a request for reading is transmitted to the microprocessor 51 and the necessary processing is executed.

In the cyclic process shown in FIG. 3(a), the slave station 5 first checks whether the door 31 is open based on the signal received from the door sensor 8 as described above (step 3o1). If the door 31 is open,
The signal from the first sensor 91 is checked, and four states are detected: when the signal changes from on to off, when it changes from off to on, on, and off, and this detection signal is used as data. It is stored in RAM 5B as . Note that in the flowchart, the first sensor 91 is shown as sensor A, and the second sensor 92 is shown as sensor B.

Then, the signal from the second sensor 92 is checked to detect four states: when the signal changes from on to off, when it changes from off to on, on, and off, and this detection signal is stored in the RAM 53 as data. Next, the first sensor 9 stored in the RAM 53 as described above is
Based on the detection signals from the first and second sensors 92,
Detects when the first -sensor 91 is on and the second sensor 92 changes from off to on, and in this case, the number of passengers is incremented by 1 and the number of passengers is counted (
Step 304). Then, based on the detection signals from the first sensor 91 and the second sensor 92 stored in the RAM 53, it is determined that the second sensor 92 is on and the first
When the sensor 91 changes from off to on, in this case, the number of people getting off the vehicle is incremented by 1, the number of people getting off the vehicle is counted (step 305), and this cyclic processing is ended.

Check step 301 before opening door 31.
If the door is closed, check from the detection state signal of the door sensor 8 whether or not the door is closed (step 311).
If it is not the time of the door closing change, the cyclic processing is terminated, but if it is the door closing change, the passenger number count value is calculated (step 312). This calculation is performed by adding the number of passengers counted in step 304 to the current number of passengers, subtracting the number of people getting off the train counted in step 305, thereby calculating a new number of passengers, and converting this number of passengers into R
Store in AM53. Then, in order to count the number of passengers when the train stops at the next station, the count values of the number of passengers getting on and the number of people getting off the train are cleared (step 313), and the cyclic processing is ended.

Next, before explaining the interrupt processing to the slave station 5 shown in FIG. 3(b), the cyclic processing of the master station 4 shown in FIG. 4(a) will be explained. This cyclic processing is also executed at one second intervals.

In FIG. 4(a), first, when the speedometer generator (TG) 6 attached to the axle of the train 3 generates an alternating current voltage due to the rotation of the axle, this alternating voltage is generated by the speedometer generator 61.
is rectified by the rectifier 61a, and the relay 61 is rectified by this rectified voltage.
b operates, thereby closing the contact of the relay 61b, and this closing signal is sent from the travel detection section 61 to the microprocessor 4 of the master station 4 via the digital interface 44 of the master station 4.
1 is input. When this input signal changes from off to on, the microprocessor 41 detects whether it is off or not (stopped) and stores it in the RAM 43 (step 40
1). Then, the state stored in this RAM 43 is checked (step 402), and if the state has changed from off to on, the process proceeds to step 403; if it is off, the process proceeds to step 411; In other cases, this cyclic processing is ended.

In step 403, a data request signal is sent to the parallel-to-serial converter 45 to take in the passenger number data held by the first one of the predetermined number 1 to n of the slave stations 5. Output to buffer.

Then, in order to organize the measurement data by station interval, the station interval count number is increased by one and stored in the RAM 43 (step 404), and this cyclic processing is ended.

Further, in step 411, when the vehicle is stopped, it is detected by the switching signal from the converter 7 that the switching is changing (switching time) or that the switching is still in the up direction or the down direction, and this is stored in the RAM 43.

Then, it is checked from the data stored in the RAM 4B whether or not it is a switching change time (step 412). If it is not a switching change time, this cyclic processing is terminated. Since this is a turnaround, the inter-station count value (2) is cleared to 0 (step 413), and this process is terminated.

The data set in the buffer of the parallel-to-serial converter 45 in step 403 is transmitted to the buffer of the first serial-to-parallel converter 56 of the slave station 5 via the transmission line 10, and when this buffer is full, the slave station 5 microprocessor 5
1 is interrupted, and the interrupt processing shown in FIG. 3(b) is executed.

In the process of FIG. 3(b), the data in the buffer of the serial/parallel converter 56 is loaded into the RAM 53 and stored (step 351), and then it is determined whether or not the communication is with the own station, that is, with the first group. Check (step 352).

If not, this process ends, but if so, the passenger count data in the RAM 53 is taken out and written to the buffer of the parallel-to-serial converter 55 for transfer (step 353), and this process is continued. finish.

As described above, data written to the buffer of the parallel-to-serial converter 55 for transfer is transferred to the buffer of the serial-to-parallel converter 46 of the master station 4 via the transmission line 10.

The serial/parallel converter 46 issues an interrupt to the microprocessor 41, and the interrupt processing to the master station 4 shown in FIG. 4(b) is executed. First, the data written in the buffer of the serial/parallel converter 46 is received and R
The data is written to the AM 43 (step 451), and then the switching state data of the converter 7, which was checked separately for up/down in step 411, and the inter-station count value counted up in step 404 are taken out from the RAM 43, and the data is read out from the RAM 43.
The number of passengers taken in is tallied (step 452). Then, the code number 2 of the next station, that is, the second category is set, and a data request is output to the buffer of the parallel-to-serial converter 45 (step 453), and the present process ends. Thereafter, the above-mentioned operations are repeated in this manner for 3 stations, 4 stations, etc. until the final station, and each time the number of passengers is added up one after another in step 452 and the number of passengers is totaled.

In the configuration of the master station 4 shown in FIG. 2(b) described above, a clock module (TM) 47 is provided to generate real time,
By reading the time via the microprocessor 41, the time can also be recorded in step 452 and added as part of the passenger count data. Furthermore, in addition to aggregating the data on the number of passengers for each station stop, by sending the number of passengers on board and the number of passengers alighting at steps 304 and 305 to the master station 4 at step 353, step 452 of the master station 4 can calculate the number of passengers and number of passengers alighting from the train. The number of people can be recorded in total, and it can also be recorded separately for each door, thereby making it possible to understand the congestion situation for each door.
