1. How to insert the data from the values array into the database in bulk? The value obtained by 
 values is: values= [[1Jing 2pje 1pcr 00pr 418223] and the length of the array is uncertain, so the length here is 2. Thank you for guidance! 
function insertData (data) {
    // console.log(data);
    // var events = [];
    var values=[];
    async.map(data,function(item,cb){
    _getNewSN({
        query:{category : "ProjectOID_" + item.ProjectOID},
        success:function(sn){
            var param=[parseInt(item.FunctionCode) ,
                        parseInt(item.StartRegister) ,  
                        parseInt(item.Length) , 
                        item.Description , 
                        item.ProjectHardwareOID , 
                        sn.SN];
            cb(null,param)
        },
        error : sender.error
    });
    },function(err,values){
        console.log(values)
        var sql = "insert into " + 
                    "plcModbusTCPDB(FunctionCode,StartRegister," + 
                    "Length,Description,ProjectHardwareOID," + 
                    "DataID) values (?,?,?,?,?,?)";
        yjDBService.exec({
            sql:sql,
            parameters : values,
            success : sender.success,
            error : sender.error
        });
