Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Example 1

As shown in fig. 1 to fig. 3, the hardware design part is specifically introduced:

DTMF transceiver circuit

The key part of the system is a DTMF transceiver circuit which realizes the functions of automatic dialing, busy tone identification, ring tone identification, remote key digital signal identification and the like to realize the remote communication of the telephone line. An MT8888 dual-tone multi-frequency (DTMF) transceiver is selected to be combined with a single chip microcomputer and an audio amplification circuit, so that detection of various signal tones and generation of DTMF signals are realized, and the DTMF signals are sent to a telephone line. MT8888 is a powerful dual tone multi-frequency (DTMF) transmitting and receiving device with an Intel microprocessor interface.

MT8888 is a DTMF signal transceiving integrated circuit produced by CMOS process, and its transmitting part adopts switched capacitor D/A converter with small signal distortion and high frequency stability, and can transmit 16 kinds of dual-tone multi-frequency DTMF signals. The receiving part is used for receiving, separating and decoding the DTMF signal and outputting the DTMF signal in a 4-bit parallel binary code mode. When sending DTMF signal, the single chip sends each digit of telephone number to MT8888, and converts it into corresponding DTMF signal to be sent to telephone line, so realizing automatic dialing.

Operating mode and register control for MT8888

MT8888 has 6 operating modes, which are: DTMF mode, CALL processing (CALL) mode, BURST (BURST) mode, single/dual tone (S/D) generation mode, TEST (TEST) mode, interrupt mode. The selection of the various modes is done by the corresponding control bits of the control registers (CRA and CRB). The selection of the working mode can be realized by setting the corresponding control bit of each register, and the registers need to be initialized after the system is powered on.

Register and control: the MT8888 has two data registers inside, one is a receive data register RDR that performs read-only operations; the other is a transmission data register TDR which performs only write operations. In addition, there are two 4-bit transmission and reception control registers CRA and CRB in the MT 8888. The operation of the CRB is controlled by a specific bit in the CRA, and therefore should be initialized during programming; the 4-bit status register SR in the MT8888 is used to reflect the operation status of receiving and signaling.

Voice circuit

In order to facilitate communication, a voice chip is adopted to realize voice prompt and alarm functions. The ISDl420 chip is a monolithic integrated voice recording and playback chip, the recording time is 20 seconds, and the ISDl420 chip can be divided into 160 segments of 125ms each. When REC pin is low level, recording, playing sound when PLAYE or PLAYL is low. The ISD1420 may record continuously or in segments.

The wireless transceiver controller comprises a coding and transmitting module and a decoding and receiving module; wherein,

coding and transmitting module

The coding signal sent by the coding chip PT2262 is formed by: the address code, the data code and the synchronous code form a complete code word. The address code must be the same as the decoding chip in the home control host to distinguish the home controller: the data code can be used to distinguish the sensor type. If the transmitting terminal makes 14 pin (TE) low, PT2262 is powered on, and the coding chip outputs a coding signal through 17 pin (DOUT). When pin 14 (TE) is high, PT2262 does not turn on the power supply, and pin 17 is low, so the 315MHz high frequency transmit circuit does not work.

Decoding and receiving module

The decoding chip PT2272 is a decoding chip corresponding to PT 2262. After the decoding chip PT2272 receives the signal, the address code of the decoding chip is compared and checked twice, the VT pin outputs high level, the high level is transmitted to INT1 of AT89C51, and an interrupt handling program is triggered to read the data code of DO-D3 so as to know the state and the alarm type of the alarm sensor.

The alarm situation acquisition adopts a wireless mode, wherein the wireless detector consists of a passive infrared pyroelectric sensor (a wireless human body detector) and a wireless door magnetic sensor. The signal from the sensor is very weak and is therefore typically amplified by an amplifier. Specifically, as shown in fig. 3, the wireless body detector sequentially includes a sensor, an amplifier, a low-pass filter, a comparator and a coding and transmitting module.
