== Overview ==
 +
 +
发射部分多是声表谐振器 (Surface Acoustic Wave Resonators)：
 +
 +
[[文件:DSC09987.JPG]]
 +
 +
常见频率 315MHz 和 433MHz
 +
 +
通电、信号脚为 1 就发射
 +
 +
发射编码部分通常用 PT2262/eV1527 编码芯片，也可直接通过程序控制发射
 +
 +
 +
亦有采用 Si4010 这类 C51 mcu 集成 OOK&FSK RF 功能的超小体积芯片解决方案

=== Input ===
 +
 +
<source lang=bash>
 +
-d 0                                        # Using the first RTL-SDR found (by default)
 +
-d driver=lime
 +
-d rtl_tcp://192.168.1.2:1234
 +
 +
# input from a file
 +
-r g001_433.92M_250k.cu8
 +
</source>
 +
 +
 +
'''Config the input:'''
 +
 +
<source lang=bash>
 +
[-f <frequency>] Receive frequency(s) (default: 433920000 Hz)
 +
[-H <seconds>] Hop interval for polling of multiple frequencies (default: 600 seconds)
 +
[-E hop | quit] Hop/Quit after outputting successful event(s)
 +
[-s <sample rate>] Set sample rate (default: 250000 Hz)
 +
[-g <gain> | help] (default: auto)
 +
[-t <settings>] apply a list of keyword=value settings for SoapySDR devices
 +
    e.g. -t "antenna=A,bandwidth=4.5M,rfnotch_ctrl=false"
 +
[-p <ppm_error>] Correct rtl-sdr tuner frequency offset error (default: 0)
 +
</source>
 +
 +
<br>
 +
 +
=== Output ===
 +
 +
The default output is to the screen
 +
 +
<source lang=bash>
 +
-F kv prints to the screen
 +
-F json prints json lines
 +
-F csv prints a csv formatted file
 +
-F mqtt sends to MQTT
 +
-F influx sends to InfluxDB
 +
 +
-F csv:log.csv    # Append output to file
 +
-F mqtt:127.0.0.1:1514
 +
</source>
 +
 +
 +
Write all received RAW data to a file with:
 +
* -w <filename>
 +
* -W <filename> to overwrite an existing file
 +
 +
 +
'''Store raw sample data:'''
 +
 +
rtl_433 can write a file for each received signal. This is the preferred mode for generating files to later analyze or add as test cases.
 +
 +
<source lang=bash>
 +
-S all to write all signals to files,
 +
-S unknown to write signals which couldn't be decoded to files,
 +
-S known to write signals that could be decoded to files.
 +
</source>
 +
 +
The saves signals are raw I/Q samples (uint8 pcm, 2 channel).
 +
 +
 +
<source lang=bash>
 +
-A      # Pulse Analyzer. Enable pulse analysis and decode attempt.
 +
-R 0    # Disable all decoders
 +
 +
-v to show detailed notes on startup,
 +
-vv to show failed decoding attempts,
 +
-vvv to show all decoding attempts,
 +

=== Modulation ===
 +
 +
<source lang=python>
 +
OOK_MC_ZEROBIT :  Manchester Code with fixed leading zero bit
 +
OOK_PCM :        Non Return to Zero coding (Pulse Code)
 +
OOK_RZ :          Return to Zero coding (Pulse Code)
 +
OOK_PPM :        Pulse Position Modulation
 +
OOK_PWM :        Pulse Width Modulation
 +
OOK_DMC :        Differential Manchester Code
 +
OOK_PIWM_RAW :    Raw Pulse Interval and Width Modulation
 +
OOK_PIWM_DC :    Differential Pulse Interval and Width Modulation
 +
OOK_MC_OSV1 :    Manchester Code for OSv1 devices
 +
FSK_PCM :        FSK Pulse Code Modulation
 +
FSK_PWM :        FSK Pulse Width Modulation
 +
FSK_MC_ZEROBIT :  Manchester Code with fixed leading zero bit
 +
</source>
 +
 +
* FSK：两个不同的频率分别代表 0 和 1，FSK 信号要想准确判定是 1 还是 0 (高频率还是低频率), 总是要等几个信号周期
 +
* OOK：On-Off Keying，当“1”出现时接通振幅为 A 的载波，“0” 出现时关断载波。是 ASK (Amplitude Shift Keying) 振幅键控调制的一个特例
 +
* ASK：相当于模拟信号中的调幅，只不过与载频信号相乘的是二进制数。移幅就是把频率、相位作为常量，而把振幅作为变量。
 +
 +
[[文件:ASK.png]]
 +
 +
如上图所示，载波经过调制之后可以有 4 个幅度，分别为 V0=00、V1=01、V2=10、V3=11, 每一个幅度可以代表  2 个 bit，这样它的传输速率就是 OOK 的 2 倍

常见频率 315MHz 和 433MHz

通电、信号脚为 1 就发射

发射编码部分通常用 PT2262/eV1527 编码芯片，也可直接通过程序控制发射


亦有采用 Si4010 这类 C51 mcu 集成 OOK&FSK RF 功能的超小体积芯片解决方案


[编辑] 2 Quick Start 

$ rtl_433 -f 433.92M -X "n=Tesla,m=OOK_MC_ZEROBIT,s=400,r=1200,t=60"
$ rtl_433 -c /usr/local/etc/rtl_433/tesla_charge-port-opener.conf

PWM

  • short: Nominal width of 1 pulse [us]
  • long: Nominal width of 0 pulse [us]
  • sync: Nominal width of sync pulse [us] (optional)

OOK_MC_ZEROBIT : Manchester Code with fixed leading zero bit


[编辑] 2.1 Input 

-d 0                                         # Using the first RTL-SDR found (by default)
-d driver=lime
-d rtl_tcp://192.168.1.2:1234

# input from a file
-r g001_433.92M_250k.cu8


Config the input: 

[-f <frequency>] Receive frequency(s) (default: 433920000 Hz)
[-H <seconds>] Hop interval for polling of multiple frequencies (default: 600 seconds)
[-E hop | quit] Hop/Quit after outputting successful event(s)
[-s <sample rate>] Set sample rate (default: 250000 Hz)
[-g <gain> | help] (default: auto)
[-t <settings>] apply a list of keyword=value settings for SoapySDR devices
     e.g. -t "antenna=A,bandwidth=4.5M,rfnotch_ctrl=false"
[-p <ppm_error>] Correct rtl-sdr tuner frequency offset error (default: 0)


[编辑] 2.2 Output

The default output is to the screen 

-F kv prints to the screen
-F json prints json lines
-F csv prints a csv formatted file
-F mqtt sends to MQTT
-F influx sends to InfluxDB

-F csv:log.csv    # Append output to file
-F mqtt:127.0.0.1:1514


Write all received RAW data to a file with:

  • -w <filename>
  • -W <filename> to overwrite an existing file


Store raw sample data:

rtl_433 can write a file for each received signal. This is the preferred mode for generating files to later analyze or add as test cases. 

-S all to write all signals to files,
-S unknown to write signals which couldn't be decoded to files,
-S known to write signals that could be decoded to files.

The saves signals are raw I/Q samples (uint8 pcm, 2 channel). 


-A       # Pulse Analyzer. Enable pulse analysis and decode attempt.
-R 0     # Disable all decoders

-v to show detailed notes on startup,
-vv to show failed decoding attempts,
-vvv to show all decoding attempts,


[编辑] 2.3 Modulation 

	OOK_MC_ZEROBIT :  Manchester Code with fixed leading zero bit
	OOK_PCM :         Non Return to Zero coding (Pulse Code)
	OOK_RZ :          Return to Zero coding (Pulse Code)
	OOK_PPM :         Pulse Position Modulation
	OOK_PWM :         Pulse Width Modulation
	OOK_DMC :         Differential Manchester Code
	OOK_PIWM_RAW :    Raw Pulse Interval and Width Modulation
	OOK_PIWM_DC :     Differential Pulse Interval and Width Modulation
	OOK_MC_OSV1 :     Manchester Code for OSv1 devices
	FSK_PCM :         FSK Pulse Code Modulation
	FSK_PWM :         FSK Pulse Width Modulation
	FSK_MC_ZEROBIT :  Manchester Code with fixed leading zero bit
  • FSK：两个不同的频率分别代表 0 和 1，FSK 信号要想准确判定是 1 还是 0 (高频率还是低频率), 总是要等几个信号周期
  • OOK：On-Off Keying，当“1”出现时接通振幅为 A 的载波，“0” 出现时关断载波。是 ASK (Amplitude Shift Keying) 振幅键控调制的一个特例
  • ASK：相当于模拟信号中的调幅，只不过与载频信号相乘的是二进制数。移幅就是把频率、相位作为常量，而把振幅作为变量。

ASK.png

如上图所示，载波经过调制之后可以有 4 个幅度，分别为 V0=00、V1=01、V2=10、V3=11, 每一个幅度可以代表 2 个 bit，这样它的传输速率就是 OOK 的 2 倍
