The present invention relates to a home alarm system, and more particularly to a home alarm system to notify the immunization date of the infant, as well as the alarm according to the temperature, humidity conditions of the room.

In the modern age of information, social workers as well as housewives who are devoted to household chores need to know and have many people to memorize.

And remember to remember the important days of family members, especially the vaccination date of infants, during the busy life. Therefore, I often write down the date required for a calendar or notebook and check the date from time to time, but I do not forget the day, but during the busy and complicated life, I often forget to check the notes on the calendar or notebook.

In particular, it is a major cause of harming health by not being able to maintain the comfort of the room because it is only known to operate the heater by the regulator or operate the air conditioner by the timer without knowing the feeling of the indoor environment according to the measured temperature and humidity. .

Accordingly, it is an object of the present invention to provide a home alarm system that informs the state of comfort in the room at normal times while informing the inoculation time and a specific day of the infant.

To this end, the present invention allows a reset signal to be input through the reset IC while controlling the overall operation using a single-chip microprocessor, but receives the date of birth of the infant through the key input unit to receive the EEPROM (Electrically Erasable Programmable Read Only Memory). It checks the timing of vaccination according to the inputted program and informs it with digital number and alarm sound.In general, it receives the temperature and humidity information through the temperature sensor to determine the state of the room and visually and auditoryly. It will let you know through.

The home alarm system of the present invention thus constructed is necessarily implemented as time passes from the date of birth of the infant as shown in the diagram of FIG. 3 in the EPROM 28 and the ROM 29 of the microprocessor 5, which is a single-chip microprocessor. While inputting information on the timing of basic immunizations to be made, a method for obtaining optimal bodily sensation state according to the correlation between temperature and humidity and a program for controlling the operation are used in advance.

When the user turns on the power (step 40), the microprocessor 5 reads the current time of the current year, month, day, hour, and minute as indicated by the minimum operating power through the time counter 8 (step 41), the positive power supply Vcc, the negative power supply Vss, and the selection signal SELECT are outputted to the LCD drive module IC4 of the display unit 12 to display the segments 12c, 12b, 12e, Selectively drive 12f to have a fast cycle, but drive the corresponding number to appear in each digit to display the current time, which is the first menu (step 42), and stage register (IC3) of the LED driver 11. The low strobe signal Strobe, the serial data signal DATA, and the clock signal CLK are outputted so that the light emitting diode LED1 representing the clock is turned on (step 43).

In this state, each time the user turns on the menu selection key SEL of the key input unit 7 once (step 44), the light emitting diode LED4 indicating the temperature and the light emitting diode LED5 indicating the notice are sequentially turned on. While notifying the type of the currently selected menu (step 45), while selectively driving segments 12a to 12f of the display unit 12, the measured value or input value of the corresponding mode, that is, the current time, the present temperature, The current humidity, date of birth entered, and notices are indicated by digital number (step 46).

If the watch mode is selected (step 47), when the digit shift key (→) is turned on once (step 48), the segment 12C, which is the first digit indicating the current time of the display unit 12, blinks and is selected. When the up key (↑) is turned on once (step 50) and the number is increased by 1 (step 51), the worm key (↓) is turned on once (step 49). Each time (step 52), the number is displayed while decreasing by one (step 53).

Here, every time the seat shift key 1 is turned on once again (step 54), the seat shift key 1 is sequentially moved to the next seat, so that the current shift time can be corrected and input (step 55).

In addition, even when the birthday mode is selected (step 56), the date of birth can be input as '○○ year ○○ month ○○ day' in the same manner as the above adjustment method (step 57).

After the date of birth is correctly input, the shift key (5) is turned on again and the microprocessor (5) is informed (step 58). Then, the microprocessor (5) recognizes the input date of birth. 9) (step 59).

If the user selects the menu of the notice (step 60), the difference is the same as the time of vaccination already entered, reading the difference from the current year and date revealed by the time counter (step 61). (Step 62), if applicable, the year, month and day to be vaccinated through the segments 12a to 12f of the display unit 12 (step 63). The voice signal corresponding to the type of vaccination is notified by voice through the voice output unit 10 (step 64).

On the other hand, when the user selects the mode of temperature (step 65), the microprocessor 5 recognizes a state in which the voltage value passing through the temperature sensor 4 increases or decreases as the temperature is high and low, and converts it into a digital signal. After receiving the present temperature (step 66), the temperature value is informed of the current temperature through the segments 12e and 12f of the display unit 12 (step 67), and through the audio output unit 10. Allow the user to hear sounds such as "hot", "cold", or the like (step 68).

In this state, if the humidity menu is selected again (step 69), the humidity sensor 3 converts the analog signal according to the voltage of 0.5V to 4V into a digital signal and calculates the humidity as a percentage of the percentage ( Step 70), by calculating the current state of the room using the temperature and humidity (step 71), and determining whether or not the comfort state based on this (step 72), the segment 12e of the display unit 12, At 12f, the current humidity is notified numerically (step 73), and the voice output unit 10 notifies the current state of the room with a simple voice (step 74).

When the menu of temperature and the menu of humidity are selected, the above operation is repeated several times for each predetermined time (step 75), and the controller returns to the standby state for the first time.

Therefore, according to the date of birth input by the home alarm system of the present invention. In addition to the date of birth, such as the current time, date of birth can be modified, and also according to the temperature and humidity of the room to let you know how to feel the modern people in complex social life to help you forget about the information to help health It can be seen that.
