onHandleIntent每秒接收一次被激活的意图而不是每30秒一次

Question

我有checkboxlist，用户选择了一些我喜欢用json格式选择的项目然后我从alarmManager向GetLLRD类发出json字符串。目前我对OnHandleIntent的意图不是每30秒，而是大约每秒或几秒钟。如何管理它以在GetLLRD类的onHandleIntent中每30秒获取一次意图？

部分输出：

07-07 17:18:01.817: I/System.out(6493): test from the onHandleIntent{"selected":[6,9]}
07-07 17:18:02.828: I/System.out(6493): test from the onHandleIntent{"selected":[6,9]}

07-07 17:18:12.907: I/System.out(6493): test from the onHandleIntent{"selected":[6,9]}

MainActivity类：

                Intent intent = new Intent(MainActivity.this,
                        GetLLRD.class);
                intent.putExtra("json_data", json);
                PendingIntent pendingIntent = PendingIntent
                        .getBroadcast(getApplicationContext(), 3,
                                intent,
                                PendingIntent.FLAG_UPDATE_CURRENT);
                AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
                Calendar cal = Calendar.getInstance();
                alarm.setRepeating(AlarmManager.RTC_WAKEUP,
                        cal.getTimeInMillis(), 30 * 1000, pendingIntent);
                startService(intent);

GetLLRD课程：

public class GetLLRD extends IntentService {

    public GetLLRD() {
        super("IntentService");

    }

    @Override
    protected void onHandleIntent(Intent intent) {

        String jSONString = intent.getStringExtra("json_data");
        System.out.println("test from the onHandleIntent" + jSONString);
        if(jSONString != null){

            System.out.println("Test");
        }

    }
}

当我尝试接收IntentReceiver中的意图时，我每隔30秒就会收到一次意图，但是在onHandleIntent中，我收到的速度太快，如前所述。

IntentReceiver：

public class IntentReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        try {
            String action = intent.getStringExtra("json_data");

            if (!action.isEmpty()) {
                System.out.println("test from IntentReiceier" + action);

            }
        } catch (Exception e) {
        }

    }
