In which the screen device 10 can be installed beside an elevator, at an entrance, at an exit, etc. of a shopping center or a mall at a place convenient for a user to use. The screen device 10 refers to a device with a screen; including but not limited to a guide device, an advertising device, a guidance device, etc. The shopping center may also be an activity center for shopping such as shopping malls and communities. Wherein the server 20 is configured to receive or transmit heartbeat packets.

In one example, the transmission device may be a Radio Frequency (RF) module, which is used for communicating with the internet in a wireless manner.
In this embodiment, a method for monitoring a screen device for network outage is provided, and fig. 2 is a flowchart of the method for monitoring a screen device for network outage in this embodiment, as shown in fig. 2, the process includes the following steps:
step S210, establishing long-chain connection between a desktop application program and a server in each screen device, and establishing a heartbeat mechanism based on the long-chain connection; the heartbeat mechanism comprises a first heartbeat time and a heartbeat packet;
step S220, determining additional time corresponding to each screen device, and generating second heartbeat time according to the additional time and the first heartbeat time;
and step S230, based on a heartbeat mechanism, transmitting heartbeat packets between the screen equipment and the server through the long chain connection at intervals of second heartbeat time so as to monitor the network disconnection of the corresponding screen equipment.
It should be noted that multiple screen devices may be installed in a shopping mall, and the desktop application in each screen device establishes a long link with the server. The long link is used for data communication between the desktop application program and the server in the screen device. The heartbeat mechanism is established based on a long-chain connection, and the heartbeat mechanism refers to a mechanism which regularly sends a self-defined heartbeat packet through the long-chain connection to enable the opposite side to know that the opposite side still lives so as to ensure the effectiveness of connection. In other embodiments, multiple screen devices may be located in different shopping malls, each screen device also establishing a long link with the server.
In this embodiment, the heartbeat mechanism includes a unidirectional heartbeat mechanism or a bidirectional heartbeat mechanism;
the one-way heartbeat mechanism is as follows: transmitting a heartbeat packet from the screen equipment to the server through the long link every second heartbeat time so as to monitor the screen equipment for network disconnection; or, transmitting the heartbeat packet to the screen device by the server through the long link at every second heartbeat time so as to monitor the screen device for network disconnection.
The bidirectional heartbeat mechanism is as follows: and transmitting a heartbeat packet to the server by the screen equipment through the long link at a second heartbeat time interval, and simultaneously transmitting the heartbeat packet to the screen equipment by the server so as to monitor the screen equipment for network disconnection. Such as: the heartbeat detection is started by a Resource Manager in the screen equipment, long-chain network call from the Resource Manager to the task execution Manager is triggered, the task execution Manager in the server receives a request and then updates the internal heartbeat time of the server and resets a heartbeat timer, then the long-chain network call from the task execution Manager to the Resource Manager is triggered, the Resource execution Manager receives the request and then updates the internal heartbeat time of the server and resets the heartbeat timer, and bidirectional detection of heartbeat is realized by using a loop detection chain. The accuracy of monitoring the broken network can be further improved through a bidirectional heartbeat mechanism, and false detection caused by unidirectional network fluctuation is avoided.
In order to avoid that a large number of clients send heartbeat packets to the server at the same fixed time, which can cause the instant pressure of the server to be too large and easily cause the crash of the server, an additional time is determined to be on the first heartbeat time to generate a second heartbeat time. Typically, the second heartbeat time is equal to the first heartbeat time plus the additional time. It is of course also possible that the second heartbeat time equals the first heartbeat time minus the additional time. The additional time may be generated by a random function built into each screen device; the additional time generated in each screen device is different; so that the time for transmitting the heartbeat packet between each screen device and the server is different. Further, the additional time can also be determined according to the pressure of the server, and when the pressure of the current server is greater than or equal to a preset pressure threshold value, the additional time is increased to delay the sending frequency of the heartbeat packet. And when the pressure of the current server is smaller than a preset pressure threshold value, reducing the additional time so as to improve the sending frequency of the heartbeat packet. Therefore, the heartbeat detection efficiency can be guaranteed, and meanwhile, too much pressure is not caused to the server. Specifically, the first heartbeat time may be 30 seconds to 1 hour; the additional time is 0.001 to 1 second.
Through the steps, on the basis of a heartbeat mechanism, heartbeat packets are transmitted between the screen equipment and the server through the long chain connection at intervals of second heartbeat time so as to monitor the network disconnection of the corresponding screen equipment; the problem that in the related art, a large number of clients send heartbeat packets to the server at fixed time at the same time, so that the instant pressure of the server is too high and the server is easy to crash is solved, and the sending time of the heartbeat packets of the large number of clients is staggered by using the second heartbeat time with additional time, so that the instant pressure of the server is reduced, and the server is prevented from crashing.
In some embodiments, the establishing of the long link between the desktop application and the server in each screen device in step S210 includes the following steps:
when a desktop application program in each screen device is started, generating a main process corresponding to the desktop application program;
based on the communication between the host process and the server to establish a long link.
Specifically, the desktop application is installed on an operating system installed on the screen device, where the operating system may be a windows, linux, macos, or android system. Desktop applications correspond to host processes one-to-one, with one desktop application corresponding to one host process. When the desktop application program is started, the operating system generates a main process corresponding to the desktop application program by default, and the communication connection between the main process and the server is the established long link.
In some embodiments, the step S230 of monitoring the screen disconnection of the corresponding screen device includes the following steps:
step S231, monitoring the corresponding screen equipment for network disconnection by using the main process;
step S232, when the network state of the screen device is monitored to be abnormal and the heartbeat packet transmitted by the receiving server is abnormal, determining that the screen device is in the disconnected state.
Specifically, a host process corresponding to the desktop application in each screen device monitors the installed screen device for a network outage. The host process may monitor not only the network state of the operating system in the host process, but also the state of the heartbeat packet. Only when the network state of the screen equipment is monitored to be abnormal and the heartbeat packet transmitted by the receiving server side is abnormal, judging that the screen equipment is in a disconnected network state; therefore, the network state abnormity of the screen equipment caused by network fluctuation in an operating system is avoided, and the misjudgment of the broken network monitoring is further caused.
In some embodiments, the method for monitoring the screen disconnection of the screen device further includes the following steps:
after a main process corresponding to the desktop application program is generated, a browsing window is created by using the main process, and a sub-process corresponding to the browsing window is generated; and the main process is in communication connection with the corresponding sub-process.
Specifically, the browse window is created and launched by the main program calling chrome. The browse window corresponds to a sub-process. The main process is in communication connection with the corresponding sub-process; the main process manages each sub-process created by the main process, the sub-processes are isolated from each other, and the sub-processes need to transmit data to other sub-processes through the main process. The sub-process is responsible for managing the browse window in which page H5 can be loaded. Such as: and transmitting the window file acquired by the cloud server to the first sub-process through the main process. The sub-process is managed through the main process, the situation that the main process is influenced by the crash of the sub-process is avoided, and viruses in the sub-process cannot influence the main process and the server.
In some embodiments, as shown in fig. 3, the method for monitoring a screen device for network outage further includes, on the basis of fig. 2, the following steps:
step S401, after the screen device is judged to be in the disconnected state, the sub-process is informed through the main process, so that the sub-process controls the browsing window to load the preset disconnected content;
and step S402, after the screen device is judged to be in the network break recovery, the sub-process is informed through the main process so that the sub-process controls the browsing window to load the playing content before the network break.
Specifically, the disconnected network content is preset in a memory of the screen device, and the disconnected network content can be a disconnected network picture or a disconnected network video; or a complete picture or video played before the network is disconnected. The main process monitors the network state through the design of the main process and the sub-process, and the sub-process is responsible for controlling the browsing window to load the preset disconnected network content into the H5, so that the coupling of the H5 to the network is reduced. When the screen device is judged to be in the off-line state, the default off-line content is played, blue screens and white screens are reduced, and experience is improved.
After the network is disconnected, the main process can wait for the recovery of the network, when the network can be recovered (4G and 5G can have flash break and can be automatically connected or connected by means), and after the screen device is judged to be in the network disconnection recovery, the playing content before the network is disconnected is played again, so that the experience feeling is improved.
In some embodiments, the method for monitoring a screen device for a network outage further includes:
and when the main process monitors that the duration of the disconnected state is longer than the preset waiting time, sending a restart message to the router through the main process so as to restart the router according to the restart message.
Specifically, the preset waiting time is calculated as follows:
the last waiting automatic recovery time = | the host process receives the network disconnection time-the network recovery time |;
the last time of router restart recovery time = | event of restarting message sent by main process-network recovery time | after router restart;
this time wait time = Min (last wait automatic recovery time, last route restart recovery time).
And after the router is restarted according to the restart message, judging the network disconnection state of the screen equipment so as to carry out corresponding processing steps. Since most network problems can be solved by router reboots. The router is restarted to attempt to recover the network by a restart message, thereby solving most network problems.
