It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The core thought of the scheme is as follows: the broadcast-level camera equipment and the geographic position information technology are organically combined, the intercommunication and interconnection of the remote broadcast-level camera equipment are realized, and the capture and transmission of remote data are realized. A control and management system of the remote broadcast-level camera is established by utilizing a cloud technology, so that the acquisition, screening, integration and display of the related data of the broadcast-level camera based on a big data environment are realized. According to the scheme, a positioning function and a system program for communication and data transmission are added to the broadcast-level camera equipment, so that monitoring and management of the broadcast-level camera equipment by a remote control terminal are realized.
Example one
The first embodiment of the application provides a remote control method, which is based on data communication between the internet and a cloud server and can transmit the current longitude and latitude and other position information of broadcast-grade camera equipment, and one or more data information of acquired image data or log files to the cloud server; the cloud server acquires information such as the use state and the position of the current broadcast-level camera equipment according to the data information, and sends control information to the broadcast-level camera equipment, so that the monitoring and management of the broadcast-level camera equipment by the remote control terminal are realized, and the aim of tracking the mobile assets is fulfilled.
Specifically, as shown in fig. 1, the method includes the steps of: s1, uploading data information to a cloud server based on the Internet; s2, based on a first trigger signal sent by the cloud server according to the data information, closing the broadcast-level camera equipment; wherein the data information comprises: one or more of location information of a broadcast-level image pickup apparatus, image data, or a log file.
In this example, the step of uploading the data information to the cloud server based on the internet includes: and uploading data information which is not uploaded completely when the computer is started for the last time or data information which needs to be uploaded when the computer is started for the current time to the cloud server. Specifically, the uploading of the data information may be uploading longitude and latitude information of a position where the current broadcast-level camera device is located, which is acquired by the broadcast-level camera device, to the cloud server; and if the longitude and latitude information of the position of the current broadcast-grade camera equipment fails to be acquired, starting GPS positioning and uploading GPS positioning information. In this example, in order to be able to grasp the position information of the broadcast-level camera in real time, the broadcast-level camera acquires latitude and longitude information of the position where the current broadcast-level camera is located through the embedded positioning device, and uploads the latitude and longitude information to the cloud server; if the longitude and latitude information of the position of the current broadcast-grade camera equipment fails to be acquired, starting GPS positioning and uploading GPS positioning information; the redundant setting obtained through the position can ensure that the broadcast-level camera shooting equipment is accurately positioned in real time, and the management and the configuration of the broadcast-level camera shooting equipment are facilitated.
The uploading of the data information can also be realized by storing the data information which is not uploaded in the last starting or the image data in the data information which needs to be uploaded in the current starting in a flash memory; and uploading the image data in the flash memory in a thumbnail transmission mode based on the detected image uploading signal. In this example, when uploading image data based on the internet, the image data to be uploaded is temporarily stored in the flash memory of the broadcast-level camera device, an uploading preparation is made, and when an image uploading signal sent by the cloud server is to be detected, the image data with transmission is subjected to thumbnail processing, and the image data in the flash memory is uploaded in a thumbnail transmission mode, so that remote image data transmission between the broadcast-level camera device and the cloud server is realized. In addition, when the image data is uploaded, the position information, the time information and the like can be simultaneously uploaded to the cloud server, so that the cloud server can conveniently manage the broadcast-level image pickup equipment and the data information thereof.

In this example, the step of turning off the broadcast-level image capturing apparatus for the first trigger signal sent by the cloud server according to the data information includes: the broadcast-level camera equipment stores data information which is not uploaded completely during the starting-up process based on a first trigger signal sent by a cloud server; and after the data information is stored, the broadcast-level camera equipment is closed. Specifically, in this example, the broadcast-level camera device stores data information that is not uploaded at this startup according to a first trigger signal sent by the cloud server; and after the data information is stored, closing the broadcast-level camera equipment. After the broadcast-level camera shooting equipment is used, the broadcast-level camera shooting equipment needs to be locked, so that the cloud server can send the shutdown control signal and simultaneously send the locking signal. The broadcast-level camera equipment locks the broadcast-level camera equipment based on the locking signal, and the broadcast-level camera equipment can be unlocked again for use when the unlocking signal is acquired; the broadcast-level camera equipment stores data information which is not uploaded when the camera equipment is started up at this time based on the shutdown control signal; and after the data information is stored, closing the broadcast-level camera equipment.
In addition, in this example, the uploading mode of the data information such as the position information, the image data, the log file and the like may be changed to uploading after shutdown according to the user requirement, and the shutdown trigger of the camera may send a shutdown instruction to the server after being triggered, and then execute the uploading task. In addition, in this example, the power-on control signal and the power-off control signal may be preset in the broadcast-level image pickup device for power-on and power-off; and when the preset time is reached, the broadcast-grade camera equipment executes the startup or shutdown according to a preset startup control signal or a preset shutdown control signal. The preset startup control signal can be a configuration instruction sent to the broadcast-level camera by using a cloud server based on the internet, and the broadcast-level camera is turned on and off according to preset time when the broadcast-level camera is started to work next time.
In this example, the broadcast-level camera device can be turned on and enter a working state according to the power-on control signal; after the camera is started, information such as starting record and the like can be sent to the server. The broadcast-level image pickup apparatus enters a locked state when not in use, and therefore, in remote control, the broadcast-level image pickup apparatus needs to unlock the broadcast-level image pickup apparatus according to the acquired unlocking signal. In this example, in order to ensure time synchronization during data transmission, the time of the broadcast-level camera is synchronized according to a standard clock sent by a cloud service, so that the time of the broadcast-level camera is always consistent with the clock on the cloud server.
According to the technical scheme, the data information of the broadcast-level camera equipment can be uploaded to the cloud server on the basis of the Internet, the cloud server sends the trigger signal to the broadcast-level camera equipment on the basis of the data information, so that the broadcast-level camera equipment is closed, the broadcast-level camera equipment is prevented from being used by other people under the condition of abnormal work tasks, and the centralized monitoring and management of the service state, the position and the like of the broadcast-level camera equipment are facilitated for managers.
