SenbayFormat 0.0.3

Senbay Icon

Overview

SenbayFormat library provides control method of sensor data format which is used in Senbay. In the sample codes, we will show you following points.

  • Compression and uncompression method for sensor data by using Base-121
  • Sensor data compression/uncompression method by SenbayFormat
  • Sensor data manegement using SensorDataManager

What's new?

Version 1.0

  • _We add a new method of getVersionNumber to SenbayDataFormatCompression. This method return a format version of SenbayFormat (Version 0 ~ 4) from a SenbayFormat text. _

Sample Code

Please open a Project on Xcode through double clicking SenbayFormat.xcodeproj.

Smaple codes is written on the main.m file.

  • Compression and uncompression method for sensor data by using Base-121
  • Sensor data compression/uncompression method by SenbayFormat
  • Sensor data manegement using SensorDataManager

Compression and uncompression method for sensor data by using Base-121

// Case of long value 
long sampleValue01 = 12345;
NSLog(@"%ld", sampleValue01);
SpecialNumber* spNum = [[SpecialNumber alloc] init];
NSString *encodedValue01 = [spNum encodeBaseX:baseNumber longValue:sampleValue01];
NSLog(@"%@", encodedValue01);
long decodedValue01 = [spNum decodeLongBaseX:baseNumber value:encodedValue01];
NSLog(@"%ld", decodedValue01);

// Case of double value
double sampleValue02 = -234.00345;
NSLog(@"%g", sampleValue02);
NSString* encodedValue02 = [spNum encodeBaseX:baseNumber doubleValue:sampleValue02];
NSLog(@"%@",encodedValue02);
double decodedValue02 = [spNum decodeDoubleBaseX:baseNumber value:encodedValue02];
NSLog(@"%g", decodedValue02);

Definition of SenbayFormat

Currenty, we have 5 version of SenbayFormat (Version 0 ~ 4) . We recommend to use Version 4.

Version Number Format Version Information Existence Compression Existence Smaple Data (Befor Compression) Sample (After Compression)
0 CSV × × 1234,0.1,0.01,-0.1 ×
1 Key-Value × × TIME:1234,ACCX:0.1,ACCY:0.01,ACCZ:-0.1 ×
2 Key-Value × ○ TIME:1234,ACCX:0.1,ACCY:0.01,ACCZ:-0.1 0xxx,1xxx,2xxx,3xxx
3 Key-Value ○ × V:3,TIME:1234,ACCX:0.1,ACCY:0.01,ACCZ:-0.1 ×
4 Key-Value ○ ○ V:4,TIME:1234,ACCX:0.1,ACCY:0.01,ACCZ:-0.1 V:4,0xxx,1xxx,2xxx,3xxx
  • xxx means characters of compressed text which is compressed by using 121 base-number compression algorithm.

Version 1 (Key-Value, No version information, No compression)

You have to set the TIME at head of a text.

NSString* sampleText02 = @"TIME:1234,ACCX:0.1,ACCY:0.01,ACCZ:0.001";
NSLog(@"%@", sampleText02);
NSLog(@"Format version is ... %d", [compressor getVersionNumber:sampleText02]);
// Get sensor data by using SenbayDataManager
SensorDataManager* manager = [[SensorDataManager alloc] init];
[manager setSensorDataString:decodedText05];
NSLog(@"%@", [manager getDataByKey:@"TIME"]);

Version 2 (Key-Value, No version information, Compression)

// [Format No.2] No version information and compression
SenbayDataFormatCompressor* compressor = [[SenbayDataFormatCompressor alloc] init];
NSString* sampleText02 = @"TIME:1234,ACCX:0.1,ACCY:0.01,ACCZ:0.001";
NSString* sampleText03 = [compressor encode:sampleText02 baseNumber:121]
NSLog(@"%@", sampleText03);
NSLog(@"Format version is ... %d", [compressor getVersionNumber:sampleText03]);
NSString* sample = @"TIME:1425941221.812044,LONG:139.635849,LATI:35.439283,ALTI:-0.109436,SPEE:0.2,ACCX:-0.140427,ACCY:-0.145172,ACCZ:-0.754669,YAW:3.269728,ROLL:-0.698060,PITC:1.455648,HEAD:50.542423,BRIG:0.360247,BATT:-1,AIRP:0,TEMP:8.149988,WEAT:'Fog',HUMI:100,WIND:3.1";

Version 3 (Key-Value, No version information, No compression)

NSString* sampleText04 = [NSString stringWithFormat:@"V:%d,%@", dataNormalVersionNumber, sampleText02];
NSLog(@"%@",sampleText04);
NSLog(@"Format version is ... %d", [compressor getVersionNumber:sampleText04]);
if([compressor getVersionNumber:sampleText04] == dataNormalVersionNumber){
  NSLog(@"%@", sampleText04);
}

Version 4 (Key-Value, Version information, Compression)

// [Format No.4] Version information and compression
NSString* sampleText05 = [NSString stringWithFormat:@"V:%d,%@",dataCompressionVerNumber, [compressor encode:sampleText02 baseNumber:baseNumber]];
NSString *decodedText05 = @"";
NSLog(@"%@",sampleText05);
NSLog(@"Format version is ... %d", [compressor getVersionNumber:sampleText05]);
if([compressor getVersionNumber:sampleText05] == dataCompressionVerNumber){
    decodedText05 = [compressor decode:sampleText05 baseNumber:baseNumber];
    NSLog(@"%@", decodedText05);
}
NSString* sample = @"TIME:1427521914.127140,LONG:139.495503,LATI:35.306662,ALTI:11.211637,SPEE:5.800000,ACCX:-1.454250,ACCY:-0.114590,ACCZ:-0.104630,YAW:0.369279,ROLL:-0.193332,PITC:0.238990,HEAD:11.522325,BRIG:0.973568,BATT:0.340000,AIRP:101.484795,TEMP:18.559991,WEAT:'Clear',HUMI:15,WIND:1.540000,HTBT:124";

Get sensor data by using SenbayDataManager

SensorDataManager* manager = [[SensorDataManager alloc] init];
[manager setSensorDataString:decodedText05];
NSLog(@"%@", [manager getDataByKey:@"TIME"]);
NSLog(@"%@", [manager getDataByKey:@"ACCX"]);
NSLog(@"%@", [manager getDataByKey:@"ACCY"]);
NSLog(@"%@", [manager getDataByKey:@"ACCZ"]);

Adding the library to your iOS project

  1. First, you should copy following files from SenbayFormat.

    • ReservedKeys.h
    • ReservedKeys.m
    • SenbayDataFormatCompressor.h
    • SenbayDataFormatCompressor.m
    • SensorDataManager.h
    • SensorDataManager.m
    • SpecialNumber.h
    • SpecialNumber.m

  2. Second, please import SenbayDataFormatCompressor.h and SensorDataManager.h at your target file.

    #import "SenbayDataFormatCompressor.h" 
#import "SensorDataManager.h"

  3. Finally, you will initialize SenbayDataFormatCompressor and SensorDataManager

    SenbayDataFormatCompressor* compressor = [[SenbayDataFormatCompressor alloc] init];
SensorDataManager* manager = [[SensorDataManager alloc] init];
