具体实施方式Detailed ways
以下结合附图，对本发明的技术方案作进一步的描述，但本发明并不限于这些实施例。The technical solutions of the present invention will be further described below with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
本发明一实施例提出一种变电站非作业区域入侵检测报警方法，如图1所示，包括以下步骤：An embodiment of the present invention provides an intrusion detection and alarm method for a substation non-operation area, as shown in FIG. 1 , including the following steps:
S1：将变电站区域划分为：作业区域和非作业区域；S1: Divide the substation area into: operation area and non-operation area;
S2：通过安装在变电站的定位系统获取作业人员的定位信息，并根据定位信息在电子地图上显示运动轨迹；S2: Obtain the positioning information of the operator through the positioning system installed in the substation, and display the movement trajectory on the electronic map according to the positioning information;
S3：当定位系统检测到作业人员入侵非作业区域时，安装在变电站的报警系统发出报警信息，安装在变电站的视频采集系统采集入侵地点的视频，并通过显示器播放入侵地点的视频，通过电子地图显示对应作业人员的运动轨迹。S3: When the positioning system detects that the operator has invaded the non-operating area, the alarm system installed in the substation will issue an alarm message, and the video acquisition system installed in the substation will collect the video of the intrusion site, and play the video of the intrusion site through the display, and use the electronic map. Displays the movement trajectory of the corresponding operator.
根据实际作业需要，将变电站的区域划分为作业区域和非作业区域。作业人员只能在规定的作业区域内进行作业，而不能进入非作业区域。作业区域和非作业区域的划分，避免了作业人员进入非作业区域而发生事故。According to the actual operation needs, the substation area is divided into operation area and non-operation area. Operators can only operate within the specified operating area, and cannot enter the non-operating area. The division of the working area and the non-working area avoids accidents caused by operators entering the non-working area.
变电站安装有定位系统，定位系统根据作业人员携带的标签，从而能够对相关的作业人员进行定位。定位系统每隔一段时间获取作业人员的定位信息，连接相邻两个时间点的定位信息从而得到运动轨迹，将该运动轨迹在电子地图上显示，能够对作业人员的运动路径进行监控。The substation is equipped with a positioning system, and the positioning system can locate the relevant operators according to the tags carried by the operators. The positioning system obtains the positioning information of the operator at regular intervals, connects the positioning information of two adjacent time points to obtain the movement track, and displays the movement track on the electronic map, which can monitor the movement path of the operator.
在划分好作业区域和非作业区域之后，作业区域和非作业区域分别由对应的坐标定位。因此，定位系统能够根据作业人员的定位信息来判断该作业人员在作业区域还是在非作业区域。当定位系统检测到作业人员入侵非作业区域时，安装在变电站的报警系统发出报警信息，安装在变电站的视频采集系统采集入侵地点的视频，并通过显示器播放入侵地点的视频，通过电子地图显示对应作业人员的运动轨迹，实现对作业人员的监控，在作业人员进入非作业区域时能够及时的报警，并且显示当时的情况便于后续处理。After the working area and the non-working area are divided, the working area and the non-working area are respectively positioned by corresponding coordinates. Therefore, the positioning system can determine whether the operator is in the work area or in the non-work area based on the operator's positioning information. When the positioning system detects that the operator has invaded the non-operating area, the alarm system installed in the substation will issue an alarm message, and the video acquisition system installed in the substation will collect the video of the intrusion site, and play the video of the intrusion site through the monitor, and display the corresponding video through the electronic map. The movement trajectory of the operator realizes the monitoring of the operator. When the operator enters the non-working area, it can alarm in time, and display the current situation for subsequent processing.
在一实施例中，为进一步的对非作业区域进行监控，非作业区域划分为：报警区域、预警区域以及屏蔽区域。其中，报警区域和预警区域采用不同程度的报警方式用以区分，而屏蔽区域为人工设置的允许作业人员暂时进入的区域。In one embodiment, in order to further monitor the non-operation area, the non-operation area is divided into: an alarm area, an early warning area and a shield area. Among them, the alarm area and the early warning area are distinguished by different degrees of alarm methods, and the shield area is a manually set area that allows operators to temporarily enter.
在布防状态下，当定位系统检测到作业人员入侵报警区域时，立即上传报警事件，同时综合管理平台上该防区区域界面进行闪动，若该防区已配置关联报警输出、视频录像功能，则立即进行相应的功能，弹出正在录制的视频；警戒区目标报警恢复后，根据该作业人员的运动轨迹以及对应的视频生成日志，可以进行回放查看，回放查看时，视频录像与运动轨迹同时在两个画面内进行播放；撤防状态下，则不做任何处理，显示运动轨迹。In the armed state, when the positioning system detects that the operator has invaded the alarm area, the alarm event will be uploaded immediately, and the area interface of the defense area on the integrated management platform will flash. Perform the corresponding function to pop up the video being recorded; after the alarm of the warning zone target is restored, a log is generated according to the movement trajectory of the operator and the corresponding video, which can be played back and viewed. During the playback review, the video recording and the movement track are displayed in two simultaneous recordings. It is played in the screen; in the disarmed state, no processing is performed, and the movement track is displayed.
在布防状态下，当定位系统检测到作业人员入侵预警区域时，立即上传预警提醒事件，若该预警区域已配置关联报警输出，可联动扩音器播放录音，警示闯入者离开，但不做视频弹窗功能，且视频不作存储。预警区目标报警恢复后，轨迹不做回放处理；撤防状态下，则不做任何处理，显示运动轨迹。In the armed state, when the positioning system detects that the operator has invaded the warning area, it will upload the warning event immediately. If the warning area has been configured with an associated alarm output, the loudspeaker can be linked to play the recording to warn the intruder to leave, but do not do anything. Video pop-up function, and the video is not stored. After the alarm of the target in the early warning area is restored, the trajectory will not be played back; in the disarmed state, no processing will be done, and the motion trajectory will be displayed.
在布防状态下，当定位系统检测到作业人员入侵屏蔽区域时，装在变电站的报警系统不发出报警信息，安装在变电站的视频采集系统不采集入侵地点的视频。In the armed state, when the positioning system detects that the operator has invaded the shielded area, the alarm system installed in the substation will not send out alarm information, and the video acquisition system installed in the substation will not collect the video of the intrusion site.
在一实施例中，定位系统根据作业人员入侵的距离来发出不同的报警信息，具体来说：In one embodiment, the positioning system sends out different alarm information according to the distance of the operator's invasion, specifically:
当定位系统检测到作业人员入侵非作业区域超过第一时间阈值且越过距离大于第一距离阈值时，报警系统发出一级告警；When the positioning system detects that the operator has invaded the non-working area beyond the first time threshold and the crossing distance is greater than the first distance threshold, the alarm system will issue a first-level alarm;
当定位系统检测到作业人员入侵非作业区域超过第二时间阈值且越过距离大于第二距离阈值时，报警系统发出二级告警。When the positioning system detects that the operator has invaded the non-working area for more than the second time threshold and the crossing distance is greater than the second distance threshold, the alarm system issues a secondary alarm.
在通常情况下，第一时间阈值为10秒，第一距离阈值为30厘米，第二时间阈值为30秒，第二距离阈值为100厘米。可以理解的是，第一时间阈值、第一距离阈值、第二时间阈值、第二距离阈值可以根据实际需要进行重新设置。Typically, the first time threshold is 10 seconds, the first distance threshold is 30 centimeters, the second time threshold is 30 seconds, and the second distance threshold is 100 centimeters. It can be understood that the first time threshold, the first distance threshold, the second time threshold, and the second distance threshold can be reset according to actual needs.
其中，一级告警包括：报警系统发出蜂鸣及光照告警信号，同时工作负责人单兵提示发生入侵告警，通过电子地图显示入侵地点。Among them, the first-level alarm includes: the alarm system sends out a buzzer and a light alarm signal, and at the same time, the person in charge of the work prompts an intrusion alarm, and the intrusion location is displayed through an electronic map.
其中，二级告警包括：报警系统语言播报当事人姓名，要求其退出非作业区域，同时工作负责人单兵追加视频采集系统追拍的图像。Among them, the second-level alarm includes: the alarm system language broadcasts the names of the parties, requiring them to exit the non-operating area, and at the same time, the person in charge of the work adds additional images captured by the video capture system.
可以理解的是，一级告警和二级告警的严重程度不同。由于二级告警时，作业人员入侵非作业区域的距离和时间均超过一级告警的距离和时间，因此更容易出现事故，所以二级告警的告警级别要高于一级告警。It is understandable that the severity of the first-level alarm and the second-level alarm is different. Since the distance and time for workers to invade the non-operating area in the second-level alarm exceeds the distance and time of the first-level alarm, accidents are more likely to occur, so the alarm level of the second-level alarm is higher than that of the first-level alarm.
针对上述一种变电站非作业区域入侵检测报警方法，本实施例还提出一种变电站非作业区域入侵检测报警系统，如图2所示，包括：Aiming at the above-mentioned method for intrusion detection and alarming in non-operating areas of substations, the present embodiment also proposes an intrusion detection and alarming system in non-operating areas of substations, as shown in FIG. 2 , including:

在本实施例中，定位系统采用UWB定位系统，每个作业人员都佩戴UWB定位标签，UWB定位系统根据UWB定位标签进行定位。UWB定位技术是采用TDOA，即到达时间差原理，利用UWB定位技术测得定位标签相对于两个不同定位基站之间无线电信号传播的时间差，从而得出定位标签相对于四组定位基站的距离差。使用TDOA技术不需要定位标签与定位基站之间进行往复通信，只需要定位标签只发射或只接收UWB信号，故能做到更高的定位动态和定位容量。In this embodiment, the positioning system adopts a UWB positioning system, each operator wears a UWB positioning label, and the UWB positioning system performs positioning according to the UWB positioning label. UWB positioning technology uses TDOA, that is, the principle of time difference of arrival. UWB positioning technology is used to measure the time difference between the positioning tag relative to the radio signal propagation between two different positioning base stations, and the distance difference between the positioning tag relative to the four groups of positioning base stations is obtained. Using TDOA technology does not require reciprocating communication between the positioning tag and the positioning base station, only the positioning tag only needs to transmit or only receive UWB signals, so it can achieve higher positioning dynamics and positioning capacity.
电子地图(Electronic map)，即数字地图，是利用计算机技术，以数字方式存储和查阅的地图。本实施例中，电子地图根据定位信息生成运动轨迹并显示的原理在上述方法实施例中已经说明，因此不再赘述。Electronic map (Electronic map), that is, digital map, is a map that is digitally stored and consulted using computer technology.
