While the air conditioning panel 1 is normally provided with a digital indicating section 11 for indicating the set temperature, this indicating section 11 is provided to indicate the heart rate when a heart rate indicating switch 12 is depressed and blood pressure value when a blood pressure indicating switch 13 is depressed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a car air conditioner control device having a panel capable of displaying signals indicating physical condition such as a heart rate monitor or a blood pressure monitor.

(Background) In recent years, the number of elderly drivers has been increasing, and since driving becomes a considerable burden, they are likely to be concerned about their own physical condition while driving. It is especially dangerous to get excited, and you must remain calm at all times.

(Objective) The present invention provides a car air conditioner control device that incorporates a heart rate needle and a blood pressure needle into an air conditioner panel so that heart rate, blood pressure, etc. can be measured during driving.

(Example) Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is an overall configuration diagram showing one embodiment.

The air conditioner panel 1 sends control signals for the vehicle air conditioner, such as temperature setting signals and air volume setting signals, and display instruction signals for heart rate and blood pressure to the microcomputer 2.
LEDs, lamps, etc. are turned on by the output signal from the.

The microcomputer 2 performs arithmetic processing according to a predetermined control program, and operates at several megahertz (MHz).
) is connected to the crystal oscillator 3 of the vehicle, and is activated by receiving a stabilized voltage from a stabilized power supply circuit (not shown) that generates a stabilized voltage based on the power supply from the vehicle battery. It is.

Air conditioning sensors 4 such as an inside temperature sensor and an outside temperature sensor, a heart rate sensor 5 and a blood pressure sensor 6 are installed inside and outside the vehicle interior, and signals i;i from these sensors are sent to an A/D converter 7. Based on the detected values of these sensors and the control signal from the air conditioner panel l, the microcomputer 2 outputs a drive command signal to the air conditioning actuators 8 and also sends a display signal to the air conditioner panel. Output.

FIG. 2 is a front view of the air conditioner panel 1. The digital display section 11 normally displays the set temperature, but when the heart rate display instruction switch 12 is pressed, the heart rate is displayed, and when the blood pressure display instruction switch 13 is pressed, the blood pressure value is displayed. What is the heart rate display instruction switch 12 and the blood pressure value display instruction switch 13?
The switch that is pressed later is valid and lights up the switch. When the selected switch is pressed again, the switch section turns off and the digital display section 11 displays the set temperature.

FIG. 3 is an installation diagram of a heart rate monitor and a blood pressure monitor. Reference numerals 5ap6a are detection parts for the heart rate sensor 5 and the blood pressure sensor 6, respectively, which are integrally formed and attached to the passenger's arm. detection unit 5a,
Heart rate sensor (main unit) that digitally processes the 6a signal
5. The blood pressure sensor (main body) 6 is located in the center console 9 and detects ff1t5a.

The connection to 6a is made so that it does not get in the way of the driver, and it can also be used by passengers in the rear seats.

By the way, your heart rate is low when you are resting and high when you are active. When the body is at rest, the amount of heat produced is low, and it is desirable to reduce heat dissipation, so a higher room temperature is more comfortable. On the other hand, when active, animals produce a large amount of heat and want to dissipate more heat, so a lower room temperature is more comfortable.

Therefore, in a car air conditioner control device that performs automatic temperature control, it is desirable to set the room temperature a little higher when the heart rate is low, and to set the room temperature a little lower when the heart rate is high.

Also, during activity, heat is carried away by the bloodstream, which causes blood vessels to dilate and blood pressure to be lower than when at rest. On the other hand, when room temperature is low, blood vessels constrict and blood pressure increases. Additionally, older people generally produce less heat and have higher blood pressure than younger people. Therefore, elderly people feel comfortable and safe at slightly higher room temperatures than younger people.

Therefore, the automatic temperature control of the car air conditioner control device may be configured to make the room temperature slightly higher when blood pressure is high.

Figure 4 shows the microcomputer 2 using the control program.

The control program includes a signal input routine 100 that receives signals from each input device. In this signal input routine, the detection signals of the air conditioning sensors 4, which are converted into binary code signals by the A/D converter 7, the heart rate sensor 5. Each detection signal from the blood pressure sensor 6 is stored in a predetermined location in RAM (temporary storage memory that can be written and read), and a switch signal from the air conditioner panel 1 is stored in a predetermined location in the RAM.

In the next target temperature calculation routine 200, a target temperature "]"set is calculated based on the set temperature Tset set on the air conditioner panel 1 and the signals from the heart rate sensor 5 and the lateral pressure sensor 6.

In the next required blowout temperature calculation routine 300, a process is performed to maintain the room temperature close to the target temperature 'p's e t' based on the signals from the air conditioning sensors 4 that indicate the environmental conditions in the passenger compartment.
