Embodiment Construction

[0040] Taking the fixed code encoding and decoding method as an example, a specific implementation of the wireless remote control 626 alarm of the present invention is introduced in detail from two aspects of hardware and software, and the specific implementation of the learning code encoding and decoding method will not be repeated here. .

[0041] refer to figure 1 , figure 2 In the circuit shown, the power supply circuit, single-chip microcomputer control circuit, and speaker drive circuit are arranged on a PCB board with a length of 5 cm and a width of 4 cm, and a pin header position for inserting a wireless decoding module is reserved on the PCB board. Among them, D1 and D2 use diodes with specifications of 1N4007, C1 uses electrolytic capacitors with specifications of 220uF 16V, C2 uses electrolytic capacitors with specifications of 100uF 10V, C3 uses ceramic capacitors with specifications of 104, and U1 uses capacitors with specifications of 78L05 Regulator IC, R1 an...

Abstract

The invention relates to a wireless remote control 626 alarm which can be matched with a wireless remote controller and a wireless detector for use by matching codes. A horn is used as an electroacoustic converting device, and wireless alarm host circuits composed of a power supply circuit, a wireless receiving decoding circuit, a single chip microcomputer control circuit and a horn driving circuit are all integrated into a hollow cavity in the horn. The wireless alarm host circuits are connected with an external direct-current power supply only through one power supply line. The wireless remote control 626 alarm is used through single chip microcomputer programming and is matched with the wireless remote controller and the wireless detector for use. The wireless remote control 626 alarm can have any one function or any two functions or all of three functions including a high-volume wireless doorbell function, a wireless remote-control alarm function and a wireless remote-control alarm function.

Description

technical field [0001] The invention relates to a wireless alarm, in particular to a wireless alarm which can be matched with a wireless remote controller and a wireless detector through code matching. Background technique [0002] The wireless doorbell is composed of a button on the wireless transmitter and a ringer on the wireless receiver. When the button on the transmitter is pressed, it will emit a wireless electromagnetic wave signal, which is received by the receiver, and the bell will emit a beautiful ringtone. Remind the owner in the room that there are guests coming from outside the door. The electromagnetic wave signal of the wireless doorbell has a long transmission distance, no wiring is required, and the installation is simple, so it is widely used in residential buildings, commercial offices and other places. However, the wireless doorbell in the prior art has a relatively small volume of ringtones, so it is only suitable for relatively quiet places. The rin...
