Description

  The present invention relates to a railway vehicle ventilation control system.

A rail vehicle has a ventilation control system having an air conditioner used to adjust the temperature in the passenger compartment for passenger comfort, and a ventilator used to take fresh fresh air into the passenger cabin, for example. There are those that have.
Conventionally, as a method for ventilation of a railway vehicle, a method has been proposed in which a maximum ventilation amount required for a passenger room is calculated in advance and the calculated value is used as a fixed value. In this method, when the ventilation operation is performed, the opening degree of the damper is fixed at the previously calculated value.
As another ventilation method, a method is also proposed in which the required rate of ventilation is calculated by calculating the vehicle occupancy rate, and the opening degree of the damper is adjusted from the calculated required rate of ventilation (for example, Patent Document 1). reference).

JP 2001-88699 A (see, for example, [0016]-[0020])

Ventilation is to supply fresh outside air into the passenger compartment, but due to the difference between the outside air temperature and the in-vehicle temperature, it becomes a load (burden) on the air conditioner, leading to an increase in power consumption of the air conditioner.
In order to suppress the load of the air conditioner, it is desirable to appropriately control the damper of the ventilator to adjust the amount of outside air taken into the cabin.

  In the method of fixing the opening of the damper with a value calculated in advance, ventilation may be performed more than necessary. That is, there is a possibility that the air will be ventilated more than the necessary ventilation amount calculated from the number of passengers present in the cabin, and there is a problem that the power consumption of the air conditioner increases accordingly.

As in the technique described in Patent Document 1, the method for calculating the required rate of ventilation by calculating the vehicle occupancy rate and adjusting the opening of the damper from the calculated required rate of ventilation is more effective than the method described above. It is considered that the power consumption of the harmony device can be suppressed.
However, in the technique described in Patent Document 1, since the opening degree of the damper is adjusted after calculating the necessary ventilation amount according to the passenger getting on and off, the time for starting ventilation is delayed correspondingly, and the air conditioner There was a problem that the driving efficiency of the vehicle also deteriorated.

For example, in vehicles where passengers frequently enter and exit, such as vehicles for stopping at each station, when the required ventilation volume is calculated and the damper opening is adjusted, the train has already started and the next station is reached. It is also possible that the train is approaching.
That is, in the technique described in Patent Document 1, even if the opening degree of the damper is adjusted, the number of passengers changes at the next station, and it becomes necessary to adjust the opening degree of the damper again. There was a problem that efficiency became worse.

  The present invention has been made in order to solve the above-described problems, and is used for a railway vehicle in which the ventilation amount of a ventilation device corresponding to the number of passengers is calculated in advance to suppress an increase in power consumption of the air conditioner. It aims to provide a ventilation control system.

[Description of Operation of Control Device 1]
FIG. 4 is an operation explanatory diagram when exchanging information on the number of passengers in the railway vehicle ventilation control system 100 according to the embodiment. A description will be given of how the control device 1 operates based on information acquired by the control device 1 of the host vehicle 19 with reference to FIG.
As shown in FIG. 4, the host vehicle 19 and the preceding vehicle 20 can exchange information via a ground communication facility 23 that collects information.
In other words, the preceding traveling vehicle 20 is equipped with the pressure sensor 14 and the like, and the control device 1 of the preceding traveling vehicle 20 calculates the passenger rate in the preceding traveling vehicle 20 from the detection result of the pressure sensor 14 and the like.
Then, the information 21 of the number of passengers output from the ground communication device 10 of the preceding traveling vehicle 20 is output once to the ground communication facility 23.
Thereafter, information 22 corresponding to the passenger number information 21 is output from the ground communication facility 23 to the ground communication device 10 of the host vehicle 19.
The control device 1 of the host vehicle 19 controls the ventilation device 2 based on the information 22 received by the ground communication device 10.

Here, the preceding traveling vehicle 20 refers to a vehicle that has already departed from the “station where the host vehicle 19 is currently heading”. That is, the control device 1 of the host vehicle 19 arrives at the “station where the host vehicle 19 is currently heading”, the passengers get on and off, the door 18 is closed, and the number of passengers is calculated based on the detection result of the pressure sensor 14. Means that the ventilator 2 is controlled using the information 21 output from the preceding traveling vehicle 20 that has already been completed.
As a feature of railway vehicles, particularly in the city center, the number of vehicles traveling on the same route is large, and the number of passengers traveling back and forth is similar. For this reason, by obtaining the number of passengers of the preceding traveling vehicle 20, the number of passengers of the own vehicle 19 expected at the next station (the station where the own vehicle 19 is currently heading) can be grasped in advance.
That is, the control device 1 of the preceding traveling vehicle 20 that has already departed from the “station where the host vehicle 19 is currently heading” has acquired information on the number of passengers at the “station where the host vehicle 19 is heading”. Therefore, if this information can be acquired, the number of passengers predicted at the next station can be grasped in advance.

The information 21 transmitted by the preceding traveling vehicle 20 to the host vehicle 19 is information regarding the “actual number of passengers” of the preceding traveling vehicle 20 calculated by the preceding traveling vehicle 20 based on the detection result of the pressure sensor 14 and the like. More details are as follows.
The preceding traveling vehicle 20 receives information on the number of passengers from a vehicle (not shown) traveling in front of the preceding traveling vehicle 20, and the preceding traveling vehicle 20 is also based on the received information. 20, the “predicted number of passengers expected at the next station” is calculated.
The information 21 transmitted by the preceding traveling vehicle 20 to the host vehicle 19 relates to “the actual number of passengers”, not “the estimated number of passengers expected at the next station”.

It is assumed that there are a plurality of vehicles corresponding to the preceding traveling vehicle 20. In this case, for example, the information 21 output from the preceding traveling vehicle 20 from the own vehicle 19 among the preceding traveling vehicles 20 may be used. Thereby, it is because the control apparatus 1 of the own vehicle 19 can acquire information with a small temporal lag.
Further, the control device 1 of the host vehicle 19 may use data other than the number of passengers of the preceding traveling vehicle 20. For example, the increase / decrease value of the number of passengers may be output from the preceding traveling vehicle 20, and the control device 1 of the host vehicle 19 may calculate the predicted ventilation volume by calculating the predicted number of passengers at the next station.
Further, the control device 1 of the host vehicle 19 may average the values of the number of passengers output from the plurality of preceding traveling vehicles 20, and the control device 1 of the host vehicle 19 may use a plurality of preceding traveling vehicles. The predicted ventilation volume may be calculated by calculating the predicted number of passengers at the next station based on the number of passengers at the next station output from the vehicle 20, the day of the week, and the time zone.

The ventilator 2 may be controlled, or the ventilator 2 may be controlled “when the passenger 18 gets on and off at the next station and the door 18 is closed”.
(Step S5)
When the control device 1 reaches the next station, the control device 1 opens the door 18, causes passengers to get on and off the vehicle 12, and then closes the door 18.
Note that the control device 1 can determine whether or not the door 18 is closed from the detection result of the door opening / closing switch 17.

(Step S6)
When determining that the door 18 is closed, the control device 1 calculates the actual number of passengers of the host vehicle 19 based on the detection results of the pressure sensor 14, the human sensor 15, and the CO ₂ sensor 16.
(Step S7)
The control device 1 outputs the calculated information on the actual number of passengers to the ground communication facility 23 in order to use the information on the vehicle traveling behind the host vehicle 19.
In addition, not only the own vehicle 19 but also the preceding traveling vehicle 20 and the vehicle running behind the own vehicle 19 receive information on the actual number of passengers of the preceding vehicle via the ground communication facility 23 in the same manner. ing.

(Step S9)
The control device 1 determines whether or not the ventilation volume is sufficient based on the predicted ventilation volume calculated in step S2 and the actually required ventilation volume calculated in step S8.
That is, when the predicted ventilation volume is smaller than the actually required ventilation volume, the control device 1 controls the damper 4 and the ventilation blower 3 of the ventilation device 2 to perform ventilation for the insufficient amount.
Further, when the predicted ventilation volume is larger than the actually required ventilation volume, the damper 4 and the ventilation blower 3 of the ventilation device 2 may not be controlled to perform ventilation.
(Step S10)
The control device 1 controls the damper 4 and the ventilation blower 3 of the ventilation device 2 based on the difference between the actually required ventilation amount calculated in step S8 and the predicted ventilation amount.
Thereafter, the control returns to step S1.

[Modification]
FIG. 6 is a modification of the embodiment shown in FIG. In FIG. 4 described above, the aspect in which the information related to the number of passengers is acquired from the preceding traveling vehicle 20 has been described, but the embodiment is not limited thereto.
