Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
The technical solution of the present application will be described below by way of specific examples.
Referring to fig. 1, a schematic diagram illustrating a remote video monitoring method for an industrial gas production enterprise according to an embodiment of the present application is shown, which specifically includes the following steps:
s101, displaying a monitoring device layout diagram of an industrial gas production enterprise on a screen of the electronic device, wherein the monitoring device layout diagram comprises a plurality of authorized monitoring devices.
It should be noted that the method may be applied to an electronic device, that is, an execution subject of the embodiment of the present application is an electronic device, and the electronic device may be a mobile phone, a tablet computer, a desktop computer, and the like.
In the embodiment of the application, the monitoring equipment can be used for monitoring the factory area, workshop and the like of the industrial gas production enterprise, and the monitoring picture is displayed through the screen of the electronic equipment, so that remote monitoring is realized.
Generally, in an industrial gas production enterprise, a large number of monitoring devices are installed in different factories and different workshops, so that a user can quickly find a monitoring device which is desired to be checked currently from the large number of monitoring devices, and the electronic device can firstly display a layout of the monitoring devices of the industrial gas production enterprise on a screen. The layout of the monitoring devices may be established according to an actual layout structure of an industrial gas production enterprise or a certain plant area within the enterprise or a certain workshop within the plant area, and installation positions of the monitoring devices are indicated in the layout.
In the embodiment of the present application, in order to further improve the convenience of a user for searching for a monitoring device, a monitoring device layout diagram displayed on a screen of an electronic device may only include a plurality of authorized monitoring devices matched with the actual permissions of a current user, that is, only the installation positions of the plurality of authorized monitoring devices that the current user has permissions to view are displayed in the monitoring device layout diagram, and for other monitoring devices that the user cannot view, the installation positions are not displayed in the monitoring device layout diagram.
In a possible implementation manner of the embodiment of the application, when a layout diagram of monitoring devices of an industrial gas production enterprise is displayed on a screen of an electronic device, personal information of a user may be first obtained, and then a plurality of authorized monitoring devices matching the user authority may be determined according to the personal information. Since each authorized monitoring device has corresponding installation location information, the electronic device can generate a monitoring device layout based on the installation location information of each authorized monitoring device and a preset layout of the industrial gas production enterprise.
For example, if a certain industrial gas production enterprise installs 9 monitoring devices, i.e., M1 to M9, in different workshops, after acquiring personal information of a user, it may be determined from the 9 monitoring devices that the user has permission to view authorized monitoring devices, i.e., M1 to M7. As shown in fig. 2, in a schematic diagram of a layout diagram of an industrial gas production enterprise provided by an embodiment of the present application, the 9 monitoring devices are respectively installed in 3 workshops shown in fig. 2. Suppose that monitoring devices M1-M4 are installed in the workshop S1, monitoring devices M5-M7 are installed in the workshop S2, and monitoring devices M8-M9 are installed in the workshop S3. Since the authorized monitoring devices that the current user has permission to view are both in the plant S1 and the plant S2, the finally generated monitoring device layout may be as shown in fig. 3, and the monitoring device layout shown in fig. 3 only includes the authorized monitoring devices that the current user has permission to view.
And S102, displaying a monitoring picture of a first monitoring device on the screen, wherein the first monitoring device is a monitoring device which belongs to the same monitoring group with at least one second monitoring device in the plurality of authorized monitoring devices.
In this embodiment, the first monitoring device may be a monitoring device that a user selects from a plurality of authorized monitoring devices and wishes to view a monitoring screen thereof. For example, the first monitoring device may be the authorized monitoring device M1 in fig. 3.
In a particular implementation, a user may operate in a monitoring device map presented by an electronic device to select a first monitoring device from a plurality of authorized monitoring devices. For example, the user may perform a click operation at the location indicated in fig. 3 as the authorized monitoring device M1, thereby instructing the electronic device to use the authorized monitoring device M1 as the first monitoring device.
In a possible implementation manner of the embodiment of the present application, the first monitoring device may belong to the same monitoring group as at least one second monitoring device. It should be noted that the second monitoring device should be an authorized monitoring device that the current user has the right to view.
In the embodiment of the present application, the plurality of second monitoring devices belonging to the same monitoring group as the first monitoring device may be monitoring devices belonging to the same workshop, for example, the authorized monitoring devices M1 to M4 in fig. 3 are all installed in the workshop S1, and the 4 authorized monitoring devices may be divided into the same monitoring group. When the user selects to view the authorized monitoring device M1, the authorized monitoring device M1 is used as a first monitoring device, and the other 3 authorized monitoring devices M2-M4 are used as second monitoring devices belonging to the same monitoring group as the first monitoring device M1.
Or, a plurality of second monitoring devices belonging to the same monitoring group as the first monitoring device may be preset by the user according to actual working needs. For example, there is a certain overlap in the monitoring areas of the authorized monitoring devices M1 to M3, so that the user can bring the 3 authorized monitoring devices M1 to M3 into the same monitoring group in advance in order to facilitate the user to view the situation of a certain area more comprehensively. When the electronic device determines that any one of the 3 authorized monitoring devices is the first monitoring device according to the operation of the user, the electronic device can automatically use the other two authorized monitoring devices as the second monitoring devices.
Or, a plurality of second monitoring devices belonging to the same monitoring group as the first monitoring device may also be determined in real time according to past viewing habits of the user. For example, in the past monitoring process, after the user finishes viewing the monitoring screen of the authorized monitoring device M1, the user often selects to view the monitoring screens of the 3 authorized monitoring devices M3 to M5. Therefore, when the electronic device determines that the authorized monitoring device M1 is the first monitoring device according to the operation of the user, the authorized monitoring devices M3-M5 can be incorporated into the unified monitoring group as the second monitoring device in real time.
When the user selects a certain authorized monitoring device as the first monitoring device, the monitoring screen of the first monitoring device is shown to be the monitoring screen which the user currently wants to view. At this time, the electronic device may display the monitoring screen of the first monitoring device on the screen.
In a specific implementation, a data transmission channel between the electronic device and the first monitoring device may be established first, and then the video stream collected by the first monitoring device is received by the electronic device through the established data transmission channel. The electronic device can generate a monitoring picture of the first monitoring device based on the received video stream, and play the monitoring picture on the screen, so that the user can conveniently check the monitoring picture.
S103, responding to an instruction of closing the monitoring screen of the first monitoring device, and generating a target layout diagram comprising each second monitoring device in the monitoring group.
In the embodiment of the application, after the user finishes viewing the monitoring screen of the first monitoring device, the user may select to close the monitoring screen. At this time, the electronic device may generate a target layout diagram including each second monitoring device in the monitoring group for an instruction of the user to close the monitoring screen.
For example, if the second monitoring device belonging to the same monitoring group as the first monitoring device M1 (authorized monitoring device M1) in fig. 3 includes the authorized monitoring devices M2 and M7 in fig. 3, the target layout generated by the electronic device should include the above-mentioned 2 authorized monitoring devices M2 and M7.
In some examples, the generated target layout may further include the first monitoring device in order to facilitate the user to understand the relative position between the second monitoring device and the first monitoring device. Thus, in the above example, the target layout finally generated by the electronic device includes the first electronic device M1 and 2 second monitoring devices, i.e., M2 and M7.
In the embodiment of the application, the magnification ratio of the target layout is larger than that of the original monitoring equipment layout. In this way, the user can quickly find the monitoring device that the user wishes to view from the enlarged-scale target layout.
In one possible implementation manner of the embodiment of the present application, the target layout may be a layout having the same length-width ratio as that of the currently used electronic device. By adjusting the target layout to be the same as the length-width ratio of the electronic equipment, the target layout can cover the screen of the electronic equipment as much as possible, and the user can conveniently check the target layout.
Therefore, in a specific implementation, the length-width ratio of the current electronic device may be determined first, and then a target layout diagram having the same length-width ratio is determined from the monitoring device layout diagram according to the length-width ratio, where the target layout diagram includes the first monitoring device and all the second monitoring devices.
As an example of the embodiment of the present application, if the electronic device is a mobile phone with a length-width ratio of about 16.
Fig. 4 is a schematic diagram of a screenshot module provided in the embodiment of the present application. Fig. 4 (a) shows 4 different gradient screenshot modules, i.e., screenshot modules P01, P02, P03, and P04, where the length-width ratio of each screenshot module is the same as the aspect ratio of the currently used electronic device. For example, in fig. 4 (a), the inclination of the segment P01 is 0, the inclination of the segment P02 is 45 degrees, the inclination of the segment P03 is 90 degrees, and the inclination of the segment P04 is 135 degrees. It should be noted that, in practical applications, the electronic device may provide more screenshot modules, and the number of the screenshot modules is not limited in the embodiment of the present application. In addition, under the condition that the length-width ratio of the screenshot module is kept unchanged, the electronic equipment can adjust the size of the screenshot module. For example, as shown in fig. 4 (b), the screenshot module is a schematic diagram obtained by partially enlarging and partially reducing the 4 screenshot modules in fig. 4 (a). Here, the screenshot blocks P11 and P14 in (b) in fig. 4 are both reduced from the screenshot blocks P01 and P04 in (a) in fig. 4, the screenshot block P13 in (b) in fig. 4 is enlarged from the screenshot block P03 in (a) in fig. 4, and the screenshot block P12 in (b) in fig. 4 is the same size as the screenshot block P02 in (a) in fig. 4. That is, the screenshot module P01 in (a) in fig. 4 is reduced to obtain the screenshot module P11 in (b) in fig. 4; after the screenshot module P03 in (a) in fig. 4 is enlarged, the screenshot module P13 in (b) in fig. 4 is obtained; reducing the screenshot module P04 in (a) in fig. 4 to obtain a screenshot module P14 in (b) in fig. 4; the size of the screenshot block P02 in (a) in fig. 4 and the screenshot block P12 in (b) in fig. 4 remains the same. The aspect ratio of each of the snapshot modules in fig. 4 (a) and (b) is the same.
After generating the multiple screenshot modules, the electronic device may use each screenshot module to perform screenshot on an area, including all the second monitoring devices, in the monitoring device layout diagram, so as to obtain multiple screenshot schematic diagrams. For example, the monitoring device layout diagram shown in fig. 2 may be subjected to screenshot by using each screenshot module shown in (a) or (b) in fig. 4, so that a plurality of screenshot diagrams obtained by screenshot include the first monitoring device and all the second monitoring devices.
Fig. 5 is a schematic diagram of generating a target layout diagram according to an embodiment of the present application. In fig. 5, it is assumed that the first monitoring device is the authorized monitoring device M1 in fig. 2, and the second monitoring device includes the authorized monitoring devices M2 and M7 in fig. 2, then the schematic diagram obtained by using the respective screenshot modules should include the authorized monitoring devices M1, M2, and M7.
It should be noted that, since the inclination of each screenshot module is different, the inclination of the obtained schematic diagram is also different. For example, the schematic diagrams of fig. 5, which are obtained by using the capture modules P01 and P02, each include the authorized monitoring devices M1, M2, and M7 of fig. 2, but the inclination of the two devices is different. Correspondingly, the sizes of the overlapping areas of the screenshot modules P01 and P02 and the original monitoring equipment layout are also different.
In the embodiment of the application, the screenshot diagram with the largest overlapping area with the monitoring device layout diagram in the plurality of screenshot diagrams can be determined as the target layout diagram. Taking the screenshot modules P01 and P02 in fig. 5 as an example, in the screenshot schematic diagram obtained by using the screenshot modules P01 and P02, the electronic device may use the schematic diagram obtained by using the screenshot module P02 as the target schematic diagram, in which the area of the overlapping region of the screenshot schematic diagram obtained by using the screenshot module P02 is larger.
And S104, displaying the target layout on the screen, wherein the target layout is used for displaying the monitoring picture of the second monitoring equipment corresponding to the operation instruction when the operation instruction aiming at any second monitoring equipment is received.
After obtaining the target layout, the electronic device may display the target layout on the screen. Fig. 6 is a schematic diagram of a target layout provided in the embodiment of the present application. In fig. 6 (a), the target layout shows the authorized monitoring devices, and the user can select any one of the authorized monitoring devices for viewing according to actual needs. For example, the user may click on the authorized monitoring device M7 in (a) in fig. 6, and then the electronic device may establish a data transmission channel with the authorized monitoring device M7 and display a monitoring screen collected by the authorized monitoring device M7 on a screen of the electronic device.
In a possible implementation manner of the embodiment of the application, since the screenshot module P02 has a certain inclination, the schematic diagram obtained by using the screenshot of the screenshot module P02 also has a certain inclination, and the target layout diagram displayed on the screen of the electronic device may not conform to the actual orientation. Therefore, the electronic device can also mark a specific orientation on the target layout. For example, in (b) of fig. 6, the electronic device marks the direction of north (S), so that the user can know the difference between the current target layout and the actual orientation through the mark information.
In another possible implementation manner of the embodiment of the application, by means of sensors such as a compass, an electronic compass, and a gyroscope in the electronic device, the user can move the north azimuth in the target layout diagram and the north azimuth in reality to a coincidence position by rotating the electronic device. For example, in (c) of fig. 6, a schematic diagram of the placement position of the electronic device after being used to rotate the electronic device is shown. At this time, the north (S) azimuth in the target map coincides with the true north azimuth. Therefore, the user can conveniently check the relative position of each authorized monitoring device, the user can conveniently check the position of each authorized monitoring device in reality, and the user can accurately and quickly find the monitoring device to be checked.
For the target layout diagram, a user can select any one of the monitoring devices by clicking the display identifier of each monitoring device in the target layout diagram, and view the monitoring picture acquired by the monitoring device.
In a possible implementation manner of the embodiment of the application, after the electronic device displays a monitoring picture of a certain monitoring device, a user may perform an operation in the monitoring picture.
In one example, the electronic device may provide functionality to view a monitoring screen of a neighboring area. Specifically, if the user wishes to view the monitoring screen of the area adjacent to the edge area of the current monitoring screen, the user may perform a long-press operation in the edge area. When the electronic device monitors a long press operation for an edge area of a current monitoring picture, it may be determined whether an adjacent area of the edge area belongs to a monitoring range of a target second monitoring device, where the target second monitoring device may be any one of a plurality of second monitoring devices. If the adjacent area belongs to the monitoring range of the target second monitoring device, that is, the adjacent area belongs to the monitoring range of a certain second monitoring device in the same monitoring group, the electronic device may directly call the target second monitoring device, and display the monitoring picture of the target second monitoring device on the screen.
For example, if the electronic device currently displays a monitoring screen of an authorized monitoring device M1 (a first monitoring device), if the user performs a long-press operation on an edge area of the monitoring screen, in response to the long-press operation, the electronic device may determine whether an adjacent area of the edge area belongs to a monitoring range of a second monitoring device in the same monitoring group. For example, if authorized monitoring devices M2 and M7 in fig. 2 are included in the same monitoring group, the electronic device may determine whether the adjacent area is located in the monitoring range of the authorized monitoring devices M2 and M7. If the authorization monitoring device belongs to the authorization monitoring device, the electronic device can directly switch the monitoring picture of the corresponding authorization monitoring device to a screen for a user to check.
If the neighboring area does not belong to the monitoring range of any second monitoring device, the electronic device may determine which monitoring device monitors the neighboring area, and add at least one neighboring monitoring device that monitors the neighboring area as the second monitoring device to the monitoring group.
Then, after receiving an instruction of closing the current monitoring screen from the user, the electronic device may display a target layout diagram including the newly added neighboring monitoring device and the original second monitoring devices on the screen.
For example, in the above example, if the monitoring ranges of the authorized monitoring devices M2 and M7 do not include the adjacent area, the electronic device may determine that the adjacent area belongs to the corresponding monitoring device based on the monitoring range information of each monitoring device. For example, the neighboring monitoring device monitoring the neighboring area may be the authorized monitoring device M3 in fig. 2, and the authorized monitoring device M3 does not belong to the same monitoring group as M1, M2, and M7. At this time, the electronic device may add the authorized monitoring device M3 (neighboring monitoring device) to the monitoring group. When the user closes the monitoring screen of the current authorized monitoring device M1, the electronic device may display a target layout diagram including the authorized monitoring devices M2, M3, and M7. The authorized monitoring devices M2 and M7 in the target layout are the second monitoring devices originally in the monitoring group, and the authorized monitoring device M3 is the neighboring monitoring device newly added to the monitoring group.
It should be noted that, because the second monitoring devices currently included in the monitoring group include newly added adjacent monitoring devices, and the monitoring ranges of the second monitoring devices are also different, the target layout diagram generated at this time is different from the target layout diagram generated according to the original second monitoring device in the monitoring group in the foregoing embodiment, but the manner of generating the target layout diagram may adopt the manner described in the foregoing embodiment, and details are not described here again.
As shown in fig. 7, which is a schematic diagram of another target layout provided in the embodiment of the present application, in (a) in fig. 7, a target layout including authorized monitoring devices M2, M3, and M7 is shown, and compared to the target layouts shown in (a), (b), and (c) in fig. 6, the target layout in (a) in fig. 7 includes an authorized monitoring device M3 (neighboring monitoring device).
In a possible implementation manner of the embodiment of the present application, before displaying the target layout diagram in (a) in fig. 7, the electronic device may further determine display identifiers of the neighboring monitoring devices and each original second monitoring device in the monitoring group in the target layout diagram, that is, determine display identifiers of the authorized monitoring device M3 and the original second monitoring devices M2 and M7.
