循环即可.

随机数的格式自己再造造

function test() {
    var arr = [];
    for (var i = 0; i < 100000; i++) {
        var date = new Date();
        var random = Math.random;
        var time = date.toLocaleDateString() + '-' + date.toLocaleTimeString().split(':').join('-') + '-' + Math.floor(random()*1000);
        arr.push({
            "seq": i,
            "time": time,
            "hrate": 0,
            "status": 0,
            "vol": [random(), random(), random(), random(), random()]
        })
    }
    return {
        "data": arr
    }
}

// 初始化你的数据
var time = 36687;
var times = time + 1000000;
var data = [];
var now = "2012-07-18-21-42-13-";
for (let m = time; m < times; m++) {
    var d = {
        hrate: 0,
        status: 0,
        vol: []
    };
    d.seq = time;
    for (let i = 0; i < 5; i++) {
        d.vol.push(Math.random() * 100);
    }
    var rand = '';
    for (let i = 0; i < 3; i++) {
        const r = Math.floor(Math.random() * 10);
        rand += r;
    }
    d.time = now + rand;
    time++;
    data.push(d);
};
console.log(data);
