Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device for a vehicle air conditioner.

Conventionally, there has been a device of this type as shown in FIG.

That is, the device shown in FIG.
Each vehicle A via.

The air conditioners 5a, 5b are supplied to the air control panels 4a, 4b, 4c, and 4d of B, C, and D.

It was controlling the operation of 5c and 5d.

In addition, in the figure, air control panels 4a, 4b, 4c, 4d
The air conditioners 5a, 5b, 5c, and 5d receive power supply voltage from a main circuit power supply 7 via a sacrificial line 6.

However, in the control device having the above configuration, the operator must control the operation of the air conditioners 5a, 5b, 5c, and 5d by operating the operation panel 1 or 2 as appropriate depending on the air condition inside the vehicle. For example, switching the operation for each season, such as cooling operation in summer, heating operation in winter, and blowing or ventilation operation in the middle of the season, pre-cooling and pre-heating when leaving the vehicle, switching operation according to changes in outside temperature, It was necessary to perform this operation every time the air conditioning conditions changed, such as switching between strong cooling operation and weak cooling operation when the car was crowded and when it was quiet.

The present invention has been made in order to eliminate the drawbacks of the conventional systems as described above.The present invention controls an air conditioner according to operating instructions based on a standard program that predetermines an annual operating schedule, and also detects the temperature outside the vehicle and calculates the detected temperature. It is an object of the present invention to provide a control device that can control an air conditioner according to an operating command that corresponds to the outside temperature when the outside temperature is outside the set temperature range.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 shows a diagram corresponding to the conventional control device shown in FIG. The storage device 11 stores therein the standard program shown in Table 1 which defines the air conditioner and the vehicle outside temperature setting program shown in Table 2 which sets the range of the vehicle outside temperature in which the air conditioner is controlled by this standard program. , inputs the detected temperature outside the vehicle detected by the temperature detector 12 via the input/output device 13, and calculates whether or not this detected temperature is within the temperature range of the vehicle exterior temperature setting program shown in Table 2; When the temperature is within the range, an operation command according to the standard program is outputted via the input/output device 13,
The central processing unit 14 outputs a driving command suitable for the outside temperature when the temperature is outside the temperature range.

In addition, in the figure, 15 is a storage battery that supplies power supply voltage to the operation command panel 10, and 16 is a start switch.

Other than that, the configuration of the control device is the same as that in FIG. 1.

Further, FIG. 3 shows the configuration of an air conditioner 5a installed in the vehicle A that operates according to the driving commands output from the driving command panel 10, in which 11 is an exhaust fan, 18 is an electric fan, 19A and 19B. is/161 cooler/162 cooler,
20A and 20B are flat l heaters and A6.2 heaters,
Further, 21 is an in-vehicle temperature detector.

It goes without saying that the configuration of the air conditioner 5a shown in FIG. 3 is similarly provided in the air conditioners 5b, 5c, and 5d.

According to the control device for an air conditioner according to the present invention, the air conditioner is automatically controlled by the idling command output from the operation command panel 10, so manual operation by the operator is required unlike the conventional one. Never.

That is, when the date and time of the current day are set and the start switch 16 is turned on when the air conditioner starts operating, the operation command panel 10 is then connected to the control panel 4a of each vehicle via the sacrificial line 3.
4b, 4c, 4d, each air conditioner 5a, 5b, 5c, 5
d is controlled.

For example, if you set the date and time as 6:00 on July 21st and give this to the input/output device 13 of the operation command panel 10, the central processing unit 14 Input the standard program shown in Table 2 and the outside temperature setting program shown in Table 2.
2, the detected temperature outside the vehicle is input via the input/output device 13, and the detected temperature is determined in the temperature range of 28°C as the upper limit and 18°C as the lower limit (from 10:00 to 16:00) as shown in Table 2. When the upper limit is 30°C and the lower limit is 18°C, an operation command according to the standard program is output.

In this case, in the air conditioner shown in FIG.
At times, the exhaust fan 17 and the electric fan 18 are operated first, and at 8 o'clock during commuting time, the /I62 cooler 19B is operated together with the 7I61 cooler 19A to perform strong cooling operation.

Then, at 10 o'clock, when the congestion inside the car is resolved and the car becomes quiet, the /I62 cooler 19B is stopped and the mode is switched to weak cooling operation.

Furthermore, it is expected that the train will be crowded again from 5:00 pm, so /162 Tara 19B will be replaced by /161 Cooler 1.
It is operated together with 9A and enters strong cooling operation, and at 20:00, this /I61 cooler 19A and Doma 2 cooler 19B are stopped.

Furthermore, the -air layer 17 and the electric fan 18 will be operated until 10 p.m.

Roughly speaking, for example, between 10:00 and 16:00, the ml cooler 19A operates in accordance with the above standard program to perform a weak cooling operation, but when the outside temperature falls outside the set temperature range shown in Table 2, that is, the temperature exceeds the upper limit of 30°C. When this occurs, the central processing unit 14 also issues an operation command to the /462 tara 19B based on the detection signal from the temperature detector 12 which detects this, resulting in strong cooling operation.

Then, the vehicle interior temperature detector 12 detects the vehicle interior temperature at this time, and when the detected temperature falls below the set value, the /16.2 cooler 19B is stopped and switches to weak cooling operation again, and the vehicle exterior temperature is within the set temperature range. The /162 Tara 19B will be operated and stopped repeatedly until the temperature reaches The air conditioner is controlled according to the program, and when a temperature outside the temperature range, that is, a temperature below the lower limit value, is detected, the air conditioner is operated at high intensity.

In the above embodiment, the dehumidifier operated according to the standard program is configured by integrating the /16.1 cooler 19A and the heater (not shown), and the /I61 cooler 19
The air cooled and dehumidified by A is passed through a heater to become dehumidified air.

As described above, according to the present invention, there is provided a temperature sensor for detecting the temperature outside the vehicle; When the detected temperature detected by the detector is within the temperature range of the vehicle outside temperature setting program, it outputs an operation command according to the standard program, and when it is outside the temperature range, it outputs an operation command for forced cooling or forced heating. It is equipped with a processing unit and can automatically control the air conditioner.
．． It is possible to easily manage the cost-effective power of the air conditioner and the maintenance cycle of the equipment by managing the turn-over time.
