Description

A mattress with an alarm

technical field

The utility model relates to the technical field of mattresses, in particular to a mattress with an alarm.

Background technique

During the use of the mobile terminal, the alarm is a function that is frequently used. An alarm can sound or vibrate at a set trigger time to remind the user to do something when the alarm is triggered. For example, when the trigger time of the early wake-up alarm set by the user on the terminal arrives, the terminal will ring a bell to remind the user to get up early.

However, in the actual application process, the effectiveness of the alarm reminder is poor. For example, after the alarm sounds, the user is still drowsy, often turns off the alarm, stays in bed for a few minutes, and often oversleeps without being reminded by the alarm.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

1-2, a mattress with an alarm includes a mattress body 1 and an alarm 2, the mattress body 1 is provided with a pressure sensor 3, and the pressure sensor 3 is connected with an A/ D converter, the A/D converter is connected with a single-chip microcomputer I, the clock chip of the alarm 2 is connected with a single-chip microcomputer II, and the single-chip microcomputer I communicates with the single-chip microcomputer II in series; the mattress body 1 has a built-in There are several motors 4, and the motors 4 are connected with relays, and the relays are connected with current transformers, and the current transformers are connected with the single-chip microcomputer I.

Please refer to Figure 3, 3-1 is the alarm circuit, 3-2 is the independent keyboard circuit, the clock chip selection is DS12C887 clock chip, the single chip selection is STC89C52 single chip, and equipped with 11.0592MHz crystal oscillator, the reset circuit adopts power-on reset , Display circuit selection using LCD1602 liquid crystal display, power selection using DC 5V power supply, the alarm circuit is composed of triode S8055, buzzer, resistor R4.

Please refer to Figure 5, 5-1 is the control circuit of the relay, which is composed of transistor Q1, 12V relay, and AC adapter, and 5-2 is the A/D converter ADC0808.

As shown in Figure 2, the relay is connected in series in the power supply circuit, and the microcontroller I and the relay form a micro-control circuit to control the on-off of the line between the motor and the power supply, thereby controlling the working state of the motor.

As shown in Figure 3, the microcontroller II is connected to the LCD1602 liquid crystal display, DS12C887 clock chip, and alarm circuit to realize the alarm function.
