请参照图2，基于上述第一实施例的系统，其管控方法包括如下步骤：Please refer to Fig. 2, based on the system of the above-mentioned first embodiment, its control method includes the following steps:
(1)构建工程项目BIM模型，并存储工程项目BIM模型中各施工对象相对应的施工信息，上述信息均存储在工程BIM数据库存储器中。(1) Build the BIM model of the engineering project, and store the construction information corresponding to each construction object in the BIM model of the engineering project.

选定施工对象的方法如下。The method of selecting construction objects is as follows.
在BIM模型中，根据安全帽的位置A(如图4所示)、水平偏移角度α和垂直倾斜角度β形成的虚拟视觉射线AD，以角度为半径建立虚拟的视角范围。同时，依据所述数据存储模块提供的BIM模型数据，对该范围内可获取的工程构件进行判定，当只检测到一个工程构件时，读取该构件的各类施工信息(包括进度信息、质量信息、安全信息、成本信息等)并推送至增强现实眼镜；当检测到虚拟视角范围内有多个工程构件时，例如图4中检测到B，C两个构件，根据设置的构件参考点B、C与安全帽位置A 分别计算距离dAB、dAC，通过对比获取距离最短的工程构件作为选定的施工对象。In the BIM model, according to the position A of the helmet (as shown in Figure 4), the virtual visual ray AD formed by the horizontal offset angle α and the vertical inclination angle β, the angle Creates a virtual viewing angle range for the radius. At the same time, according to the BIM model data provided by the data storage module, the engineering components that can be obtained within this range are judged, and when only one engineering component is detected, various construction information (including progress information, quality information, etc.) of the component are read. information, security information, cost information, etc.) and pushed to the augmented reality glasses; when multiple engineering components are detected within the virtual viewing angle, for example, two components B and C are detected in Figure 4, according to the set component reference point B , C and helmet position A to calculate the distances dAB , dAC respectively, and obtain the engineering component with the shortest distance as the selected construction object through comparison.
由于BIM模型数据本身就包含了各个工程构件的所有几何信息(例如尺寸、坐标)，因此任意点的坐标在BIM模型中都是已知的。构件参考点可根据需要自行在BIM模型中进行设定，上面的示例是选择构件中心作为参考点。Since the BIM model data itself contains all the geometric information (such as dimensions and coordinates) of each engineering component, the coordinates of any point are known in the BIM model. The reference point of the component can be set in the BIM model according to the needs. The above example is to select the center of the component as the reference point.

为了优化操作，提升用户使用体验，本实施例还包括信息推送判断步骤，信息推送判断步骤可以设于步骤(1)～(5)中任意相邻两个步骤之间，用于需要查看施工信息时执行后续步骤，而不需要查看施工信息时，则暂停或终止后续步骤的执行。由于步骤(3)要占用处理器进行运算处理，为缓解处理器压力，本实施例将信息推送判断步骤设置在步骤(2)和步骤(3)之间(如图3)。In order to optimize the operation and improve the user experience, this embodiment also includes an information push judgment step, which can be set between any two adjacent steps in steps (1) to (5), for the need to view construction information When the subsequent steps are executed, and there is no need to view the construction information, the execution of the subsequent steps is paused or terminated. Since step (3) will occupy the processor for calculation and processing, in order to alleviate the pressure on the processor, this embodiment sets the information push judgment step between step (2) and step (3) (as shown in Figure 3).
为进一步优化用户体验，方便管理人员对施工现场的观察和管控，本实施例中，当增强现实眼镜成功显示施工信息之后，将显示的内容定格。具体的，在本实施例中，触发手动开关，启动信息推送程序，当增强现实眼镜接收到施工信息以后，显示该施工信息，并自动将显示内容定格，当显示内容定格时，系统不再根据安全帽的位姿变化更新显示内容。再按触发一次手动开关，则显示的内容消失。当下一次再触发手动开关时，系统又重新根据安全帽的位姿变化来更新增强现实眼镜的显示内容。在显示内容定格的时间内，用户可以自由进行其他活动，比如现场一边看着显示的内容一边下达管控指令，避免遗忘刚刚看到的施工信息。In order to further optimize the user experience and facilitate the observation and control of the construction site by managers, in this embodiment, after the augmented reality glasses successfully display the construction information, the displayed content is frozen. Specifically, in this embodiment, the manual switch is triggered to start the information push program. After the augmented reality glasses receive the construction information, they display the construction information and automatically freeze the displayed content. When the displayed content is frozen, the system no longer The pose change of the helmet updates the displayed content. Press the trigger manual switch again, and the displayed content will disappear. When the manual switch is triggered next time, the system will update the display content of the augmented reality glasses according to the change of the helmet's pose.

在其他实施例中(未图示)，施工信息推送开关是自动开关，为安装在安全帽本体上的速度检测仪，检测到安全帽移动时停止推送，检测到安全帽静止时启动推送。或者，施工信息推送开关由基于BIM的施工信息管控单元的处理器兼任，当处理器检测到安全帽本体的位置、朝向和角度信息维持一定时间不变，则启动施工信息推送；当处理器检测到接收的安全帽本体的位置、朝向和角度信息中的任意一个发生变化，则停止施工信息推送。In other embodiments (not shown), the construction information push switch is an automatic switch, which is a speed detector installed on the helmet body, stops pushing when it detects that the helmet is moving, and starts pushing when it detects that the helmet is still. Alternatively, the construction information push switch is concurrently served by the processor of the BIM-based construction information management and control unit. When the processor detects that the position, orientation and angle information of the helmet body remains unchanged for a certain period of time, the construction information push is started; when the processor detects If any of the received position, orientation and angle information of the helmet body changes, the construction information push will stop.
在其他实施例中(未图示)，也可以预设显示内容的定格时间，比如10秒或20秒，可以按照使用者的个人习惯自行设定，也可以出厂时预置。在预设的显示时间之内，仍然可以通过触发施工信息推送开关来停止显示。In other embodiments (not shown), the freeze time of the displayed content can also be preset, such as 10 seconds or 20 seconds, which can be set according to the user's personal habits, or can be preset at the factory. Within the preset display time, the display can still be stopped by triggering the construction information push switch.
在其他实施例中(未图示)，增强现实安全帽上设有画面定格开关， 画面定格开关连接增强现实眼镜，用于手动控制将增强眼镜上显示的画面定格或停止显示。In other embodiments (not shown), a frame freeze switch is provided on the augmented reality helmet, and the frame freeze switch is connected to the augmented reality glasses for manual control of freezing or stopping the display of the frames displayed on the augmented reality glasses.
在其他实施例中(未图示)，步骤(3)中选定施工对象的方法如下：根据读取的位姿信息，在BIM模型中模拟安全帽的位置A、水平偏移角度α和垂直倾斜角度β，根据A、α、β建立虚拟视觉射线AD，将BIM模型中与虚拟视觉射线AD干涉的第一个施工对象作为选定施工对象。In other embodiments (not shown), the method for selecting the construction object in step (3) is as follows: according to the read pose information, simulate the position A of the helmet, the horizontal offset angle α and the vertical angle α in the BIM model Inclination angle β, establish virtual visual ray AD according to A, α, β, and take the first construction object that interferes with virtual visual ray AD in the BIM model as the selected construction object.
在其他实施例中(未图示)，可以通过双击施工信息推送开关实现信息推送的开启与关闭，通过单击操作施工信息推送开关来实现显示内容的定格与清除。In other embodiments (not shown), the information push can be turned on and off by double-clicking the construction information push switch, and the display content can be frozen and cleared by clicking the construction information push switch.
在其他实施例中(未图示)，可以通过长按施工信息推送开关实现信息推送的开启与关闭，通过双击施工信息推送开关实现显示内容的定格与清除，步骤(3)中当虚拟视角范围内有多个施工对象时，通过单击施工信息推送开关来实现选定施工对象的切换。In other embodiments (not shown), the information push can be turned on and off by long pressing the construction information push switch, and the display content can be frozen and cleared by double-clicking the construction information push switch. In step (3), when the virtual viewing angle range When there are multiple construction objects, the selected construction object can be switched by clicking the construction information push switch.
