Drools：如何编写在入口点没有数据时会命中的规则

如何解决Drools：如何编写在入口点没有数据时会命中的规则

我是流口水的新手。我希望传感器数据能够从跟踪设备（例如标签设备）发送数据。我正在使用Drools 入口来跟踪传感器数据。我需要基于此传感器数据对某些事件进行警报。

DRL文件如下

import com.sample.AlertRuleModel;

declare AlertRuleModel 
    @role( event )
    @timestamp( timespamp )
end

rule "No signals are coming from any entry-point for more than 10s"
     when
        $f : AlertRuleModel() from entry-point "AlertRuleStream"
        not(AlertRuleModel(this != $f,this after[0s,10s] $f) from entry-point "AlertRuleStream")
    then
        $f.setRuleId(1);
        <Do alert here>
end

rule "Rule on Tag1 has not been in zone1 for more than 1 minutes"
     when
         $f : AlertRuleModel( tagId == 1,zoneId == 1 ) from entry-point "AlertRuleStream"
         not(AlertRuleModel(this != $f,tagId == 1,zoneId != 1,1m] $f) from entry-point "AlertRuleStream")
    then
         $f.setRuleId(2);
        <Do alert here>
end

Java代码

    kSession = RuleExecutionService.getKieSession(packetProcessorData.getAlertRuleDrlPath());
    ruleStream = kSession.getEntryPoint("AlertRuleStream");
    kSession.addEventListener(new DefaultAgendaEventListener() {
        public void afterMatchFired(AfterMatchFiredEvent event) {
            super.afterMatchFired(event);
            onPostExecution(event,RuleTypeEnum.ALERT_RULE.getName());
        }
    });
    
    new Thread() {
        @Override
        public void run() {
            kSession.fireUntilHalt();
        }
    }.start();

流数据插入部分

private BlockingQueue<AlertRuleModel> alertFactQueue;
.
.
AlertRuleModel alertRuleModel = null;
while (true) {
    alertRuleModel = alertFactQueue.poll(1,TimeUnit.SECONDS);
    if (alertRuleModel != null) {
        //LOGGER.debug("Inserting alertRuleModel into \"AlertRuleStream\"");
        ruleStream.insert(alertRuleModel);
        continue;
    } 

    try {
        Thread.sleep(1000);
    } catch (InterruptedException e) {
        LOGGER.error("Exception while sleeping thread during alertFactQueue polling..",e);
    }

}

但是当我运行应用程序时，

1. 第一个规则“在10s内没有任何信号从任何入口点发出”根本没有命中。我不知道为什么，请告诉我我做错了什么还是语法错误是第一个规则。
2. 在第二条规则“ Tag1不在zone1中超过1分钟”的情况下，当我通过tagId == 1和zoneId == 1传递事实时，它总是立即被击中。我尝试了不同的时间间隔，例如之后[0s，10m] 。但是在传递具有上述值的事实后，它仍然会立即命中。

请告诉我我在哪里犯错误..？
