Detailed ways

The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention and should not be construed as limiting the present invention.

The following describes a mobile terminal and a real-time online monitoring system for excavation construction according to embodiments of the present invention with reference to the accompanying drawings.

The mobile terminal for excavation construction proposed by the embodiment of the present invention can be configured on an excavator on a construction site.

The mobile terminal can detect the relative position between the excavator and the underground pipeline in real time, and display the real-time pipeline relative position positioning layer.

The real-time pipeline relative position positioning layer includes a virtual electronic map layer, a pipeline map layer that are superimposed on each other, and a real-time positioning layer containing the position information of the excavator. Therefore, according to the displayed real-time pipeline relative position positioning layer, the relative position between the excavator and the underground pipeline can be known in real time, so as to avoid the underground pipeline excavation during the construction process, and improve the construction safety.

As a possible implementation manner of this embodiment, as shown in FIG. 1 , the mobile terminal 110 may include: an MCU module 111 , a GPS differential positioning module 112 and a power supply module 113 .

The MCU module 111 , the GPS differential positioning module 112 and the power supply module 113 are electrically connected to each other, the GPS differential positioning module 112 is electrically connected to the GPS positioning antenna, and the power supply module 113 mainly supplies power to each module in the terminal.

The GPS differential positioning module 112 may use the GPS differential positioning method to obtain the position information of the excavator. Specifically, the GPS differential positioning module 112 can provide real-time longitude and latitude positioning information of the excavator.

The MCU module 111 can obtain the position information of the excavator from the GPS differential positioning module 112, and generate a real-time positioning layer. Then, the real-time positioning layer is superimposed with the pre-stored pipeline map layer and the pre-stored virtual electronic map layer to obtain a real-time pipeline relative position positioning layer for display. The real-time pipeline relative position positioning layer carries the relative position information between the excavator and the underground pipeline.

Specifically, the MCU module 111 superimposes the pipeline map layer and the virtual electronic map layer to determine the position of the underground pipeline in the virtual electronic map. Then, superimpose the real-time positioning layer with the superimposed pipeline map layer and the virtual electronic map again to determine the position of the excavator in the virtual electronic map, so that the position of the underground pipeline in the virtual electronic map and the excavator can be determined according to the position of the underground pipeline in the virtual electronic map. The position in the virtual electronic map, determine the relative position.

In this embodiment, the relative position includes the distance between the excavator and the nearest underground pipeline, and the distance here can be understood as the linear Euclidean distance between the excavator and the nearest underground pipeline. Specifically, the linear Euclidean distance between the excavator and the nearest underground pipeline can be calculated according to the position of the underground pipeline in the virtual electronic map and the position information of the excavator in the virtual electronic map.

As a result, the operator can grasp the location information of the underground pipeline in real time, and does not need to compare the paper map, thus greatly improving the work efficiency of the operator and ensuring the stability and safety of the underground pipeline.

In order to further improve the safety of construction, a multi-level distance threshold can be preset, and the mobile terminal 110 can give an early warning according to the distance between the excavator and the nearest underground pipeline and the multi-level distance threshold.

Specifically, the MCU module 111 compares the distance between the excavator and the nearest underground pipeline with a preset multi-level distance threshold, and when the distance between the excavator and the nearest underground pipeline is lower than the previous distance threshold After that, generate an alarm prompt corresponding to the upper-level distance threshold, and continue to compare with the next-level distance threshold until the distance between the excavator and the nearest underground pipeline is lower than the last-level distance threshold.

For example, set 5-level distance thresholds, which are 10m, 8m, 7m, 5m, and 3m, respectively, and the distance threshold of 3m corresponds to the highest level. The MCU module 111 compares the distance between the excavator and the nearest underground pipeline with the above-mentioned level from the low level distance threshold to the high level distance threshold. Suppose. If the distance between the excavator and the nearest underground pipeline is 7.5m, the MCU module 111 now compares 7.5m with 10m. Since 7.5m is less than 10m, an alarm corresponding to 10m is generated. After that, compare 7.5m with the next-level distance threshold of 8m. Since 7.5m is less than 8m, an alarm corresponding to 8m is generated. Next, compare 7.5m with 7m. Since 7.5m is greater than 7m, the alarm condition corresponding to 7m has not been reached, so the alarm corresponding to 7m will not be issued.

In order to improve the accuracy of the alarm, the multi-level distance thresholds in this embodiment can be obtained according to the statistics of the distance between the excavator and the underground pipeline when the excavation accident corresponding to the dangerous level occurs, and the multi-level distance threshold corresponds to the corresponding dangerous level. alarm prompt. By gradually comparing the distance between the excavator and the nearest underground pipeline with the multi-level distance threshold, the operator is constantly reminded, and normal construction can be carried out without digging the underground pipeline.

Further, in an embodiment of the present invention, based on FIG. 1 , as shown in FIG. 2 , the mobile terminal 110 may further include: an image transmission module 114 , a data transmission module 115 and an audio module 116 .

The image transmission module 114, which is electrically connected to the MCU module 111, can send one or more combinations of the virtual electronic map layer, the pipeline map layer and the real-time positioning layer through the transmission antenna to the monitoring platform commanded by the construction site or the real-time location layer. Online Monitoring Center. It should be noted that the monitoring center may be located at a certain construction site or at other places.

The data transmission module 115 is electrically connected with the MCU module 111 and the GPS differential positioning module 112, and can transmit the position information of the excavator obtained by the GPS differential positioning module 112 and the relative position between the excavator and the underground pipeline obtained by the MCU module through the transmission antenna One or more combinations of information and operator information stored by the MCU module 111 .

The audio module 116 may play audio received through the transmission antenna and transmit the captured audio through the transmission antenna. Specifically, the audio module 116 can receive the voice information sent by the monitoring platform or the monitoring center through the transmission antenna, such as voice scheduling information for the excavator, and play the voice information. The audio module 116 can also collect the voice information of the operator, such as the construction situation of the excavator, the situation of the construction site, etc., and transmit it to the monitoring platform or the monitoring center through the transmission antenna.

In this embodiment, the GPS positioning antenna electrically connected to the GPS differential positioning module 112 is independent of the transmission antenna.

In this embodiment, the image transmission module 114, the data transmission module 115 and the audio module 116 can transmit the data of the construction site to the monitoring platform or the monitoring center through the transmission antenna, so that the monitoring personnel can understand the construction site through the monitoring platform or the monitoring center The construction situation, such as construction process, construction number, construction personnel information, etc., is convenient for command and dispatch.

It should be noted that the modules in the mobile terminal 110 are not limited to the MCU module 111 , the GPS differential positioning module 112 , the power supply module 113 , the image transmission module 114 , the data transmission module 115 and the audio module 116 , and other new functional modules may be required , scale horizontally.

Since excavators usually work in places with harsh ground environment, it is also very necessary to fix the mobile terminal.

As an implementation manner, each module in the mobile terminal 110 is disposed inside the casing of the mobile terminal 110, and the casing is connected with the shock absorbing member.

As shown in FIG. 3 , the housing 210 is fixedly connected to one end of the shock absorbing member 220 , and the other end of the shock absorbing member 220 is fixedly connected to one side of the support plane 230 . The other side of the support plane 230 is rotatably connected to one end of the support rod 240 , and the other end of the support rod 240 is fixedly connected to the suction cup 250 . The suction cup 250 can be fixed on the surface of the center console of the excavator, so that the operator can observe the content displayed on the mobile terminal 110 .

The shock absorbing member 220 includes a plurality of shock absorbing balls. As shown in FIG. 3, there are two shock absorbing balls on one side, so the shock absorbing balls on both sides add up to 4 shock absorbing balls, which can reduce the movement of the excavator. Vibration brought by mobile terminals.

The mobile terminal for excavation construction according to the embodiment of the present invention can detect the relative position between the excavator and the underground pipeline in real time, and display the real-time pipeline relative position positioning layer, so that the operator of the excavator can understand the excavator and the underground pipeline in real time. The relative position between the pipelines can avoid cutting the underground pipelines during the working process of the excavator and improve the safety of construction.

In order to realize the above embodiments, the present invention also proposes a real-time online monitoring system for excavation construction.

The mobile terminal 110 is connected to the monitoring platform 120 , and the monitoring platform 120 is connected to the monitoring center 130 . It can be understood that the connection here is a communication connection.

Specifically, there may be several excavators at the construction site of urban excavation, each excavator is equipped with a mobile terminal 110, and the mobile terminal 110 can detect the relative position between the excavator and the underground pipeline in real time. During specific implementation, the mobile terminal 110 may be fixed in the above-mentioned manner.

The monitoring platform 120, used for construction site command, can be located near the construction site, collects construction conditions at the construction site from the mobile terminal 110, communicates with the mobile terminal 110, and commands the excavators in the construction site where the monitoring platform 120 is located.

The monitoring center 130 is used for real-time online monitoring, and can collect the construction situation of each construction site from the monitoring platform 120 within the monitoring range, and conduct real-time supervision on the construction site. Wherein, the monitoring center 130 may be divided into districts or cities, and each monitoring center 130 may simultaneously supervise multiple construction sites within the range.

In addition to detecting the relative position between the excavator and the underground pipeline in real time, the mobile terminal 110 can also record the working route of the excavator, record the generated alarm information, and verify or manage the identity information of the excavator operator.

The alarm information may include the alarm time, the vertical distance between the excavator and the underground pipeline during the alarm, and the like.

As an example, before the excavator operator performs construction, the operator may first input identity information such as a job number in the mobile terminal 110, and the mobile terminal 110 compares the received identity information with the pre-stored identity information. If the identity information is consistent with the input identity information, the operator can be allowed to operate the excavator, thereby avoiding the danger caused by the operation of the excavator by people other than the operator, and improving the safety of construction. It should be noted that the identity information may also be the biometric information of the operator, such as fingerprints, faces, and the like.

The mobile terminal 110 can also manage the operator's identity information, for example, it can delete the pre-stored identity information according to the deletion instruction, or add the operator's identity information according to the adding command, which has high flexibility.

The monitoring platform 120 can communicate with the mobile terminal 110, and collect the construction situation of the construction site from the mobile terminal 110, such as the construction time, the number of construction workers, and the alarm situation within the construction time.

The scheduling message may carry target location information and/or target working status to which the excavator is scheduled.

If the dispatching message carries the target location information or target working state to which the excavator is dispatched, the mobile terminal 110 can move the excavator from the current position to the corresponding target position information after receiving the dispatching information sent by the monitoring platform 120 . location, or switch the excavator from the current working state to the target working state.

If the dispatching message carries the target location information or target working state to which the excavator is dispatched, the mobile terminal 110 can move the excavator from the current location to the location corresponding to the target location information after receiving the dispatching information sent by the monitoring platform 120 . , and switch the excavator from the current working state to the target working state.

In order to improve the work efficiency of the operator, the scheduling information can be a reminder message in the form of voice. After the mobile terminal 110 receives the reminder message, it can send a reminder to the operator through the installed broadcast device, so that the operator can operate the excavator according to the broadcast information. , compared to the text display on the mobile terminal, it is convenient for the operator to operate the excavator.

In this embodiment, the monitoring personnel can monitor the construction site online and command and dispatch the excavator through the monitoring platform.

In an implementation manner of the embodiment of the present invention, when it is determined that the excavator is close to the underground pipeline, the monitoring platform 120 may send the identification of the underground pipeline to the monitoring center 130 . After receiving the identifier of the underground pipeline, the monitoring center 130 can query the remark information corresponding to the received identifier of the underground pipeline according to the stored identifier of the underground pipeline and the corresponding remark information, and return to the monitoring platform 120 . Among them, the remark information includes but is not limited to the material of the underground pipeline, whether it has been repaired, etc.

The monitoring platform 120 receives the remark information of the underground pipeline returned by the monitoring center 130, and sends the remark information to the mobile terminal 110 for display to the operator, so that the operator can understand the specific situation of the underground pipeline and facilitate construction.

Further, the monitoring platform 120 can also obtain the current location information of the excavator and the basic information of the operator from the mobile terminal 110 in real time, so as to supervise the construction site.

When the current operator needs to take over the shift, the monitoring platform 120 may also receive remark information reported by the current operator through the mobile terminal 110 , such as remarks in the construction process, or precautions and the like. When a new operator operates the excavator again, the monitoring platform 120 can send the remarks of the current operator to the mobile terminal 110 to be displayed to the new operator, so as to improve work efficiency.

In an embodiment of the present invention, based on FIG. 4 , as shown in FIG. 5 , the monitoring center 130 may include a display screen 131 and an interaction module 132 .

Among them, the database 133 is used to store construction information of each construction site.

The monitoring center 130 can selectively focus on a designated construction site. Specifically, when the monitoring personnel want to observe the construction situation of a certain construction site, they can click to select the construction site. The display screen 131 receives the selection operation, and determines the selected construction site according to the selection operation, and then searches and obtains the construction information of the construction site from the database, such as the personnel information of the operator, the driving track of the excavator, and the historical alarm information of the excavator. , detailed information of the mining accident, etc., are displayed on the display screen 131 .

It should be noted that the functional modules of the monitoring center 130 are not limited to the display screen 131, the interaction module 132, the database 133 and the negotiation module 134, and can be extended horizontally when other new functional modules are required. In practical applications, each functional module may have a dedicated person in charge, and the functional module can be called by the dedicated personnel to trigger the processing flow of the functional module.
