1.设置通道音量大小，静音，延时控制等
2.读取通道音量小大，静音状态
3.按钮，拉条，联动控制等
4.多通道合并控制
5.设置最大，最小，初使音量值
6.拉条显示，百分比显示，按钮反馈等。
7.设置控件对应通道
8.灵活替换控制代码
9.灵活修改控制方法

*********************************************************************************************************************
********************************************************************************************************************/
创建设备方法(端口，波特率，检验位，数据位，停止位，控制命令回调方法，数据接收回调方法)
var dev_Volume = new _AUDIO('MOD',9600,N,8,1,volCommand,volReceive);
MOD为模版接口，根据向导生成指定的接口，可是COM1-COM8，NET1-NETX
9600,N,8,1为根据串口指令生成，使用网控制控制时，补齐位数，也需要填写，值任意
volCommand为控制命令的回调方法，用于填写不同品牌设备的控制命令
volReceive为数据接收回调方法，用于设备数据返回接收。
默认音量设置
dev_Volume.setLevelInit();
第1位为程序座标0，不起作用，从第2位即为程序对应的通道1.
最大音量
dev_Volume.setLevelMax();
第1位为程序座标0，不起作用，从第2位即为程序对应的通道1.
最小音量
dev_Volume.setLevelMini();
第1位为程序座标0，不起作用，从第2位即为程序对应的通道1.
默认静音
dev_Volume.setMuteInit();
第1位为程序座标0，不起作用，从第2位即为程序对应的通道1.第一次值程序有效，其它的会从中控读取上一次设置值
合并控制
dev_Volume.setCombine(1,2,3);
控制通道1时同时控制通道2，3，当有些音频控制需要同时控制时，可使用音频合并方法。
关联按钮初使化
dev_Volume.setInit('barVolume','txtVolume','btnVolumeMute',24);
最后做按钮关联控制，将拉条显示，百分比显示，静音反馈及总输入输出通道合并。
如初使化最大音量，最小音量，初使音量，初使静音与_AUDIO默认一致，可不设置。
控制命令：
根据控制命令，定义输入输出模块对应的通道名称,对应控制模块号从BIAMP软件查看
var aLevelName = ['','Out_Name_1_01','Out_Name_1_02', 'Out_Name_1_03', 'Out_Name_1_04', 'Out_Name_1_05', 'Out_Name_1_06', 'Out_Name_1_07', 'Out_Name_1_08'];
var aMuteName = ['','Out_Name_1_01','Out_Name_1_02', 'Out_Name_1_03', 'Out_Name_1_04', 'Out_Name_1_05', 'Out_Name_1_06', 'Out_Name_1_07', 'Out_Name_1_08']
function volCommand(vCMD,vChannel)
{
switch(vCMD)
{
//音量控制
case 'value':
return "SET 1 FDRLVL "+aLevelName+" 1 "+dev_Volume.level+"\x0D";
break;
//静音
case 'mute':
return "SET 1 FDRMUTE "+aMuteName+" 1 "+dev_Volume.mute+"\x0D"
break;
}
}
volCommand为前面定义的回调方法，vCMD为返加类型参数，返加value为音量控制，返回mute为静音控制。vChannel为控制通道。
返回数据：
function volReceive(vData)
{
sendLog("volReceive:",vData);
}
volReceive为前面定义的返回数据回调方法，vData为返回的数据，根据数据执行所需要的控制。
音量控制：
dev_Volume.volup(vSelect)
通道音量加，vSelect代表通道号
dev_Volume.voldown(vSelect)
通道音量减，vSelect代表通道号
dev_Volume.setLevel(vSelect,vLevel)
通道音量设置，vSelect代表通道号，vLevel代表音量值，根据最大和小最音量的取值范围；用于直接控制音量静音，如模式调用。
dev_Volume.delayLevel(vSec,SvSelect,vLevel)
延时通道音量设置，vSec为延时时间，单位为秒，vSelect代表通道号，vLevel代表音量值，根据最大和小最音量的取值范围；用于直接控制音量
静音，如模式调用，同一台设备多条指令同时发送间隔。
静音控制：
dev_Volume.volmute(vSelect)
通道静音，vSelect代表通道号
dev_Volume.setMute(vSelect,vValue)
通道静音，vSelect代表通道号，vValue代表静音值0或1；用于直接控制音量静音，如模式调用。
dev_Volume.delayMute(vSec,SvSelect,vValue)
延时通道静音，vSec为延时时间，单位为秒，vSelect代表通道号，vValue代表静音值0或1；用于直接控制音量静音，如模式调用，同一台设备多
条指令同时发送间隔。
关联控制：
dev_Volume.setCombine(vSelect,n1,n2...);
通道关联与取消，如：dev_Volume.setCombine(1,2,3);将2，3通道关联至1通道，控制1通道时，同时会控制通道2，3; 如需取消通道1与其它通道
的关联，则代码为dev_Volume.setCombine(1);
获取状态：
dev_Volume.getStatus();
获取所控制通道状态，并同步到触摸屏，当软件退出重新打开时，可调用此方法，同步触摸屏与中控的数据，保持数据的一致性。
dev_Volume.getLevel(vSelect);
获取指定通道音量，vSelect为指定通道，返回最小与最大音量值区间。
dev_Volume.getMute(vSelect);
获取指定通道静音值，vSelect为指定通道，返回0，1；
端口发码：
dev_Volume.setBaud(9600,N,8,1);
设置对应接口的波特率真
dev_Volume.sendCodeString(“xxxx“);
发送接口命令
dev_Volume.delayCodeString(“xxxx“);
延时发送接口命令
dev_Volume.sendCodeName(“xxxx“);
调用数据库名称
dev_Volume.delayCodeName(“xxxx“);
延时调用数据库名称
端口发码的主要目的是使用dev_Volume代替原有的sendCodeString(COM1,xxxxx)增加程序的可读性。
原型修改：
如果对于_AUDIO原型方法，需要修改或者需要增加，可使用如下方法：
修改方法：
delete dev_Volume.volup;
_AUDIO.prototype.volup = function(vSelect)
{
this.level = getSystemInt(this.barname+vSelect, this.level);
if(this.level<this.valueMax)
{
this.level = this.level+2;
}
else
{
this.level = this.valueMax;
}
sendCodeString(this.port,this.getCMD('value',vSelect));
this.setStatus(vSelect);
this.setCombineLevel(vSelect);
return this.level;
}
在查看原型方法时存在，音量加volup是每次加1，如果根据情况需要每次加2，那么可以删除原来的方法并重新构造，修改里面的相关参数，如上所示。
注：删除原型方法会使用所有调用原型的方法都改变，如果一个项目存在两台音频处理器，都同时调用_AUDIO两个方法都会跟着改变。
如果一台需要改变，另一台不需要，则可使用直接增加方法2的方式，如下所示：
增加方法：
_AUDIO.prototype.volup2 = function(vSelect)
{
this.level = getSystemInt(this.barname+vSelect, this.level);
if(this.level<this.valueMax)
{
this.level = this.level+2;
}
else
{
this.level = this.valueMax;
}
sendCodeString(this.port,this.getCMD('value',vSelect));
this.setStatus(vSelect);
this.setCombineLevel(vSelect);
return this.level;
}
