Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart illustrating a monitoring method for a playback device according to an embodiment of the present invention, where the method may be executed by a main control device, and the main control device may be a desktop, a notebook computer, or an intelligent terminal. As shown in fig. 1, the monitoring method provided in this embodiment specifically includes the following steps:
s110: and acquiring the operation information of the user on the target file.
The target file may be a video file, an application software installation package (APK), an upgrade file, or the like. The user can operate the target file according to the self requirement.
For example, the operation information in this embodiment may include, but is not limited to, video file push, video on demand, system upgrade, and status acquisition of the playing device. Correspondingly, the control instruction corresponding to the operation information may also include: a file push instruction, a video on demand instruction, a system upgrade instruction or a state acquisition instruction, and the like.
S120: and sending the control instruction corresponding to the operation information to the at least one playing device based on the communication connection with the at least one playing device, so that the at least one playing device executes the operation corresponding to the control instruction.
For example, the main control device may send a search instruction to at least one playback device, where the search instruction includes an IP address and a port number of the main control device. After receiving the search instruction, the playing device can judge whether connection with the main control device is established according to the IP address and the port number, and if the playing device is judged to be in the connection state with the main control device, the playing device sends a message to the main control device to inform the main control device of the connection state of the playing device; and if the playing device judges that the connection with the main control device is not established, the playing device replies communication connection information to the main control device after receiving a search instruction sent by the main control device. And the main control equipment establishes communication connection with the playing equipment according to the communication connection information.
Specifically, in order to increase the transmission speed of the search instruction, the main control device may send the search instruction to the at least one playback device based on a UDP communication Protocol (user datagram Protocol).
For example, the establishment of the communication relationship between the main control device and the at least one playing device may be performed before the main control device acquires the operation information of the user, or may be performed after the main control device acquires the operation information of the user, which is not specifically limited in this embodiment. The communication connection established between the main control device and the plurality of playing devices may be a wireless communication connection within the coverage of a local area network.
Further, after establishing a communication connection with the main control device, the playback device may send a "heartbeat packet" (a self-defined command word between the client and the server that regularly notifies the other party of its own status) at set time intervals (for example, 5 minutes), where the "heartbeat packet" is used to determine a connection status between the main control device and at least one playback device. If the master control equipment does not receive the heartbeat packet within the set time, the communication connection is abnormal, and the connection needs to be disconnected for fault processing.
For example, the playback device may also actively send a connection request to the main control device, for example, a "bubble" command may be sent to the main control device through a UDP communication protocol to notify the main control device that the playback device is already in an online state, and wait for obtaining a search command sent by the main control device. After receiving the connection request, the main control device can send a search command and establish communication connection with at least one playing device at the same time.
For example, after the main control device establishes a communication connection with at least one playback device, a control instruction corresponding to the operation information of the user may be sent to the at least one playback device to perform unified control on the multiple playback devices.
Specifically, if the operation information is video on demand information, the step of sending the control instruction corresponding to the operation information to the at least one playback device based on the communication connection with the at least one playback device, so that the at least one device performs the operation corresponding to the control instruction may specifically be:
converting the video file to be played into a data stream, and sending a playing address corresponding to the data stream to at least one playing device, so that the at least one playing device plays the video file based on the playing address. The setting can realize the function of one-key video-on-demand, and also can keep the playing progress of a plurality of playing devices uniform so that the main control device can monitor. In addition, the main control device can also play the video on demand synchronously so as to monitor the playing progress of a plurality of playing devices in real time.
Optionally, in the above process, after the main control device obtains the operation information of the user, the NGINX server may be operated, and an RTMP (Real Time Messaging Protocol) live streaming server is built to perform Real-Time transmission on the data stream. Specifically, after the user selects a video file to be played, an open source computer program ffmpeg (fast Forward mpeg) may be adopted to convert the video file to be played into a data stream, and send the data stream to the RTMP live streaming server, and then send a play address corresponding to the data stream to the at least one play device through a TCP protocol, so that the at least one play device plays the video file based on the play address.
For example, when the play mode of the play device is not set, the play device may play the on-demand stream in a default play mode.
Further, for application scenarios such as product releases, product developers can select a play mode of the video file on the main control device, and can display the play effect of the video file in different play modes to users. The playback mode may be a 2D mode, a 3D mode, a VR mode, or a VR3D mode. The main control device can obtain the switching operation of the playing mode and send a corresponding switching instruction of the playing mode to the playing device, and the playing device executes the switching action of the playing mode after receiving the instruction.
Optionally, if a user wants to switch the playing mode of the playing device by himself, the mode switching key on the playing device may be triggered to select the playing mode meeting the watching requirement of the user. When the user finishes the switching of the playing mode, the main control device can acquire the current playing mode of the playing device so as to monitor the playing state of the playing device in real time.
For example, if the operation information is system upgrade information, correspondingly, based on the communication connection with the at least one playback device, the control instruction corresponding to the operation information is sent to the at least one playback device, so that the at least one device may specifically perform an operation corresponding to the control instruction:
detecting the current system version number of at least one playing device, and judging whether the current system version number is matched with the version number of a preset upgrading version or not; and if not, sending the upgrade file corresponding to the preset upgrade version to at least one playing device, so that the at least one playing device can cover the upgrade file with the original system file for upgrading. The advantage of the above arrangement is that the master control device can avoid installing the upgrade files in a plurality of playing devices respectively, and realize the unified upgrade of the plurality of playing devices.
Furthermore, the playing device can feed the upgrading progress back to the main control device in real time in the process of receiving the files for upgrading, so that the main control device can monitor the upgrading progress of the plurality of playing devices simultaneously. The reason for this is that if an abnormal situation occurs due to a network reason or unpredictable thereof in the upgrading process, the fault can be known in real time and eliminated in time so as to recover the normal upgrading process of the playing device.
In addition, the main control device can push the upgrade file, and can simultaneously send the software application installation package or other files to a plurality of playing devices. The main control equipment can send corresponding files according to operation information of users, a playing equipment user can also send a file obtaining request to the main control equipment according to self requirements, and the main control equipment can send the corresponding files to the playing equipment after receiving the request so as to meet actual requirements of the playing equipment user and improve user experience.
The embodiment of the invention provides a monitoring method of playing equipment, which can send a control instruction corresponding to operation information to at least one playing equipment based on communication connection with the at least one playing equipment by acquiring the operation information of a user on a target file, so that the at least one playing equipment executes the operation corresponding to the control instruction. By adopting the technical scheme, the synchronous control of a plurality of playing devices is realized, convenience is provided for the management of a large number of playing devices, and the user experience of users of the playing devices is improved.
Example two
Fig. 2 is a schematic flow chart of a monitoring method for a playback device according to a second embodiment of the present invention, where this embodiment is optimized based on the foregoing embodiment, and referring to fig. 2, the monitoring method provided in this embodiment may specifically include:
s210: and sending a search command to at least one playing device.
S220: and receiving communication connection information returned by the at least one playing device, and establishing communication connection with the at least one playing device according to the communication connection information.
S230: and generating a device list according to the communication connection information, wherein the device list is used for recording the attribute information of at least one playing device.
For example, the attribute information of the playback device may be information such as a Media Access Control (MAC) name, an electric quantity, a default playback mode, and a default playback volume of the playback device. The device list is established to facilitate real-time monitoring of different states of different playback devices. Especially for the case where there are a large number of playback devices, various attribute information of different playback devices can be accurately viewed from the device list.
Preferably, the attribute information may further include power consumption information. Correspondingly, the method provided by the embodiment may further include:
reading the current residual capacity of the playing device from the device list; determining the playing device with the current remaining power lower than a set threshold power (for example, only 10% of power remains) as a target playing device; and sending a charging instruction to the target playing equipment, wherein the charging instruction is used for driving the target playing equipment to send out a warning so as to position the target playing equipment.
For example, as long as the playback device is in a power-on state, the current remaining power of the playback device can be obtained in real time and displayed in the device list, so that the user can know the power consumption conditions of different playback devices and can charge the playback device with insufficient power in time.
For example, after receiving the charging instruction, the target device may automatically send an alarm sound, so that the staff may locate the target device according to the alarm sound. The advantage of setting up like this lies in, for the condition that the playback devices is great in quantity, because it is difficult to obtain the residual capacity of every playback device in proper order, also is difficult to find target device in a plurality of playback devices simultaneously, consequently, sends the warning sound through drive target device, can confirm the position that target device is located in numerous playback devices according to sound to charge for target device fast.
Furthermore, a warning light can be installed on each playing device, when the working state of the target device is abnormal, for example, the electric quantity is too low or the network connection fails, the warning light can be driven to light, and the worker can accurately determine the position of the target device according to the warning light and the warning sound.
In addition, the staff may also check the states of different playback devices in the device list periodically, and if a certain playback device needs to be used multiple times in a recent period of time (e.g., a week) and consumes more power, the staff needs to replenish the power for the next normal use after each use. At this time, the worker can drive the playing device to send out an alarm by double-clicking the name corresponding to the playing device in the device list, so that the worker can determine the position of the playing device.
S240: and acquiring the operation information of the user on the target file.
S250: and sending the control instruction corresponding to the operation information to the at least one playing device based on the communication connection with the at least one playing device, so that the at least one playing device executes the operation corresponding to the control instruction.
The present embodiment optimizes the above embodiments, and after the multiple playback devices establish communication connection with the main control device, the device list is generated in the main control device in real time, so that the device list can be used to record attribute information of the multiple playback devices. The state of the playing device can be obtained in real time through the attribute information, and for some playing devices with abnormity, such as playing devices with low electric quantity, the abnormal devices can be driven to send out warning sounds by clicking the names of the abnormal devices in the device list by a user. For the condition that a large number of playing devices exist, the warning sound can help workers to locate abnormal devices, and convenience is brought to unified management of the large number of playing devices.
