(Prior Art) Most recent railcars are provided with an air conditioner. Such an air conditioner uses a DC power input from a pantograph 1 as an auxiliary power source as shown in FIG. 2, where an air-conditioning power source is generated and supplied to an air conditioner 3 provided for each vehicle. In this case, as shown in FIG. 4, each air conditioner 3 includes a temperature detector 5 responsive to an output detected by the temperature sensor 4, a contactor 6 activated by the operation of the temperature detector 5, and a contactor 6. It consists of a compressor 7 operated via the contacts 61 of the vessel 6. In addition, 8 is an air-conditioning input command switch.

Such an air conditioner 3 detects the temperature inside the vehicle by the temperature sensor 4, and for example, when the detected value becomes equal to or higher than a predetermined set temperature, operates the temperature detector 5 to energize the contactor 6. Then, the compressor 7 is shifted to the operating state via the contact 61, and when the detected value falls below the predetermined set temperature, the temperature detector 5 is returned to deactivate the contactor 6 and the contact 61 And the operation of the compressor 7 is stopped.

(Problems to be Solved by the Invention) By the way, in such a configuration, for example, as shown in FIG.
Assuming that the vehicle interior temperature 10 changes with respect to the temperature set value 9 as shown in FIG.
(C) As shown in (d), the air conditioners 3 of A, B, and C may be simultaneously controlled. (Even if the temperature set value 9 differs for each air conditioner 3, the same applies to the case where the in-vehicle temperature 10 coincides with the temperature set value 9 at the same time.) However, the three-phase generally used for the compressor 7 of the air conditioner 3 It has been known that the starting current of an induction motor is five times that of a normal operation.
When a plurality of devices are started at the same time, an extremely large current flows. This is because the auxiliary power supply 2 used as a power supply for these air conditioners 3 is usually set to have a rating slightly higher than the starting current of one air conditioner 3. When activated, the auxiliary power supply 2 becomes extremely overloaded, which causes a drawback that the protection function is activated and the operation of the air conditioner 3 of all vehicles is stopped.

(Operation) According to the above-described means, the present invention is not limited to the case where the start and stop commands are issued for each of the plurality of air conditioners at the same time, but the case where the start and stop commands are issued for the plurality of air conditioners. Since each air conditioner is started and stopped at the start and stop points set for each air conditioner so that the air conditioners deviate at predetermined intervals, the load fluctuation of the power supply of each air conditioner is always changed by one air conditioner. , The overload state of the power supply can be prevented, and the inconvenience of activating the protection function and stopping the operation of all air conditioners due to this can be prevented.

(実施例) 以下、本発明の一実施例を図面にしたがい説明する。Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

(ここでは、n=2)にしている。
In this case, the operation timings of the air conditioners 3 of A, B, and C are set as shown in FIG. That is, the A air conditioner 3 is operated in the range of the synchronization time T1, the B air conditioner 3 is operated in the range of the synchronization time T2 shifted by the time Ta from the synchronization time T1, and the C air conditioner 3 is operated in the synchronization time T2. The operation is performed in the range of the synchronization time T3 which is further shifted by the time Ta. Then, the synchronization times T1, T2, and T3 are equally divided at time t. In this case, the division time t is 1 / n of the predetermined time Ta.
(Here, n = 2).

そして、各同期時間T1、T2、T3毎に時間tの単位でず

Then, the start and stop points S1, S2, S3 of each air conditioner are set so as to be shifted in units of time t for each of the synchronization times T1, T2, T3. Therefore, A of the synchronization time T1 in this case
The point at which the air conditioner 3 can be started and stopped S1 is shifted from the point at which the air conditioner 3 is started and stopped by a time 2t.
S2 is present, and the C air conditioner 3 has a start / stop point S3 with a further delay of 2t.

By setting the operation timing in this way, the temperature set value for each air conditioner 3 is now set as shown in FIG.
If the vehicle interior temperature 12 changes with respect to this temperature set value 11, the vehicle interior temperature 12 is now set at point P1 in the figure.
When the temperature falls below the temperature set value 11, a stop command is issued simultaneously to each of the air conditioners A, B, and C. The operation of the air conditioner 3 is stopped, and the time t
B air conditioner 3 with start and stop point S2 with only a delay
Is stopped and finally started with a further delay of t,
The operation of the A air conditioner 3 having the stop point S1 is stopped.

その後、図示P2点で車内温度12が温度設定値11を上回

Thereafter, when the vehicle interior temperature 12 exceeds the temperature set value 11 at the illustrated P2 point, a start command is simultaneously issued to each of the A air conditioner, the B air conditioner, and the C air conditioner. This time, first, the operation of the B air conditioner 3 having the start and stop points S2 is started, and the operation of the A air conditioner 3 having the start and stop points S1 is started with a delay of time t later than this. Then, the operation of the C air conditioner 3 having the start / stop point S31 is further started with a delay of the time t.

Therefore, if it does in this way, each A, B, and C air conditioner 3
Since the start and stop timings of the air conditioners can be reliably prevented, the power supply for driving these air conditioners can always keep the load fluctuation within the range when one air conditioner starts up. A material having a small overload capacity can be used. Conventionally, since a plurality of air conditioners are conventionally started and stopped at a time, a remarkable overload condition is caused to the power supply, and as a result, the protection function is operated to operate the air conditioners of all vehicles. Although such a situation may occur, such a situation can be prevented beforehand, and the operation of a plurality of air conditioners can be reliably and stably controlled.

[Effects of the Invention] As described above, according to the present invention, in any case where the start and stop commands are issued simultaneously for each of a plurality of air conditioners, not when the start and stop commands are issued, Since each air conditioner is started and stopped at the start and stop points set for each air conditioner so as to be deviated at predetermined time intervals among a plurality of air conditioners, the load fluctuation of the power supply of each air conditioner is constantly changed. One air conditioner can be stopped within the range at the time of start-up, and it is possible to prevent overload state on the power supply, and to prevent inconvenience such as stopping the operation of all air conditioners due to the protection function operating due to this Can be.
