Description

Technical Field

[0001] The present invention relates to the field of Internet of Things device configuration, and in particular to a remote monitoring method and system. Background Art

[0002] The Internet of Things technology has been widely used in various fields, realizing the interconnection between things and things, people and things, etc., facilitating user management and control, and allowing users to fully experience the convenience and speed brought by the Internet of Things technology. With the increase in smart sensor modules, the Internet of Things has higher and higher requirements for communication stability.

[0003] With the advent of the 5G era, China's 5G network is developing rapidly. 5G has the characteristics of high transmission rate and low latency, and WiFi6 and MU-MIMO technologies are mature.

[0004] In the past, video surveillance equipment needed to be connected to the Internet through network cables, which needed to be laid out and then connected to the Internet. Alternatively, LTE cellular networks could be used, but due to the low speed of LTE networks, it could only meet the needs of ordinary data transmission and was somewhat incapable of high-definition video transmission.

[0005] Currently, the general CPE or 5G module does not support monitoring equipment. This solution can realize remote monitoring of CPE equipment and monitoring camera online status, and for faults caused by external reasons, such as telecommunications operator network failure, arrears shutdown, equipment failure, etc. Under these faults, the device will not be able to connect to the Internet, so it cannot receive instructions from the outside. This solution has designed a retry and recovery solution for CPE in the event of a fault. At the same time, the server detects offline devices and makes corresponding processing. For faults that can be solved automatically, they will be automatically processed. For those that cannot be processed, the relevant personnel will be alerted. After the relevant personnel handle it, the device will resume connection. After the network connection is restored, data can be reported normally, equipment can be remotely controlled, and videos can be uploaded to the cloud server. This solution will bring great convenience to relevant management personnel and reduce the frequency of relevant personnel having to go to the site to solve problems.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0034] CPE, the full name of which is Customer Premise Equipment, is actually a mobile signal access device that receives mobile signals and forwards them as wireless WIFI signals. It is also a device that converts high-speed 4G or 5G signals into WiFi signals, and can support a large number of mobile terminals accessing the Internet at the same time. CPE can be widely used in wireless network access in rural areas, towns, hospitals, units, factories, communities, etc., which can save the cost of laying wired networks.

[0035] See also Figure 1 , Figure 1 The present invention is a flowchart of a remote monitoring method according to an embodiment of the present invention. The remote monitoring method comprises the following steps:

[0036] Step S100: receiving data and periodically checking the CPE device to find the offline CPE device and the monitoring device connected to the CPE device;

[0037] The CPE reports data regularly, and the cloud server determines whether the CPE device is offline based on the reported data. For example, the user list of the monitoring devices connected to the CPE is uploaded to the cloud server. The cloud server can detect the cellular network connection status of the CPE and the monitoring device information connected to the CPE.

[0038] Step S200: Check whether the offline CPE device belongs to one of the preset situations, wherein the preset situation includes insufficient CPE device tariff, offline monitoring device, and server failure;

[0039] Generally, there are two reasons for CPE device offline: software and hardware. Software reasons can be solved by restarting, and hardware reasons can be solved by manual processing. However, if the offline caused by software reasons is also handled manually, it will cost a lot of manpower, and the execution efficiency and recovery rate will be low.

[0040] Therefore, remote monitoring can be achieved through software judgment and control, thereby improving monitoring efficiency and reducing labor costs.

[0041] Specifically, check whether the CPE device fails to report for N consecutive cycles, then restart the CPE device to connect to the network, and terminate if the CPE device is successfully connected to the network. If the CPE device fails to connect to the network, determine whether the number of restarts of the CPE device meets the preset number, and if so, take a variable period to retry the network connection; where N≥1.

[0042] For example, if the CPE device fails to report for N consecutive cycles and the cloud server does not receive the data reported by the CPE device for N cycles, the failure may be caused by network reasons. If it is determined that the cellular network cannot be connected and the restart number is less than the maximum restart number, the modem module is restarted.

[0043] If the CPE device still cannot connect to the network after restarting, the CPE device connects to another high-availability server. If the network connection is successful, it is determined that the server is faulty and a fault alarm notification is issued. For example, the CPE device detects the cellular network connection status, sends an ICMP packet to another high-availability server, and successfully connects to the high-availability server, then it is determined that the original server is faulty.

[0044] If the number of restarts reaches the maximum number of restarts, the device will retry the cellular connection in a variable period, such as 5s, 10s, 30s, 1min, 3min, and 5min. After reaching the maximum step length of the cellular connection, the cellular connection will be retried periodically according to the maximum step length. If the network failure is caused by external reasons, the CPE device can successfully connect to the network after the external reasons are resolved.

[0045] Step S300: If the CPE device fee is insufficient, the CPE device is automatically recharged, or if the monitoring device is offline, a fault alarm notification is issued.

[0046] Furthermore, if it is monitored that the CPE device is offline for more than 2N periods, it is actively queried whether the tariff of the CPE device is lower than a preset threshold, wherein N is greater than or equal to 1.

[0047] If the cloud server monitors that a CPE has been offline for more than N*2 cycles, it can proactively check whether the CPE's tariff is normal. If it is due to an accident (such as automatic recharge failure, etc.), it will immediately initiate automatic recharge and notify relevant personnel to pay attention to the situation. The cloud server should regularly check the equipment tariff. If it finds that the tariff is lower than the preset threshold, it should initiate an automatic renewal application, and the management personnel can process it after receiving the application.

[0048] In the technical solution provided by the present invention, data is received and periodic checks are performed on CPE devices to discover offline CPE devices and monitoring devices connected to the CPE devices; the offline CPE devices are checked to see if they fall into one of the preset situations, including insufficient charges for the CPE devices, offline monitoring devices, and server failures; if the charges for the CPE devices are insufficient, the CPE devices are automatically recharged, or if the monitoring devices are offline, a fault alarm notification is issued. This technical solution allows remote monitoring of the operating status of CPE devices and monitoring devices, and can achieve reconnection of offline devices through automatic monitoring, saving a lot of labor costs.

[0049] Furthermore, the remote monitoring method further includes the following contents:

[0050] When the monitoring device applies to connect to the CPE device, the cloud server queries the nearby CPE list based on the location information of the monitoring device, determines the appropriate CPE device, sends the SSID and password information to the CPE device, and writes the SSID and password to the monitoring device. The cloud server can control the format of the reported data, the target service address of the reported data, the reporting cycle and other parameters.

[0051] The cloud server can also control the users authorized to connect to the CPE. For example, if a monitoring device is connected to the CPE device via Wi-Fi / network cable, the relevant personnel should obtain authorization in the cloud and add the monitoring device to the Wi-Fi whitelist and cellular network whitelist. Only then can the user (such as a monitoring device) connect to the CPE and connect to the Internet through the CPE. The cloud server can also control the firewall of the CPE to only allow designated addresses and ports to be accessed, thereby enhancing security.

[0052] like Figure 2The flowchart of the monitoring method implemented on the CPE side. If a monitoring device goes offline, for example, the wrong version is used or the wrong configuration file is written when upgrading the version, it will lose contact with the cloud server. However, through the data reported by the CPE (user list), it is found that the device can be connected to the CPE normally (for example, the monitoring device reports that the service program is hung). Then the CPE can be used as an agent to control the faulty monitoring device to perform corresponding operations: such as resetting a module. The monitoring device can also be controlled to initiate self-test and complete self-repair. It is also possible to use the minimum system to complete the firmware update through the CPE when the monitoring device firmware is defective and cannot work normally. Specifically including the following steps:

[0053] Step S201: The cloud server finds that a monitoring device is offline;

[0054] Step S202: Check whether the device is connected from the data reported by the CPE;

[0055] If yes, execute step S203, if no, execute step S212;

[0056] Step S203: Sending a command to the CPE to enable it to start the proxy mode;

[0057] The CPE sends a command to the monitoring device to put it into a fault recovery mode;

[0058] Step S204: The cloud server uses the CPE as a proxy to check the configuration and status of the monitoring device;

[0059] Step S205: Determine whether the CPE is successfully connected to the monitoring device;

[0060] If yes, execute step S207, if no, execute step S212;

[0061] Step S208: After discovering the problem, the cloud server sends instructions or data to the CPE to modify the configuration of the monitoring device or upgrade the version;

[0062] Step S209: CPE forwards data and instructions to the monitoring device;

[0063] Step S210: monitoring device execution instructions and data;

[0064] Step S211: Determine whether the monitoring device is restored;

[0065] If yes, stop. If no, check the configuration and status of the monitoring device again through the cloud and CPE as a proxy.

[0066] Through the above method, the CPE device can be used as an intermediary, and the cloud server can control the monitoring device through the CPE device agent, which can help the monitoring device to resume monitoring, perform restart, version upgrade, etc. It has the advantages of low cost control and convenient control.

[0069] The CPE device includes a checking and judging module, which is used to check whether the CPE device fails to report for N consecutive cycles, then restart the CPE device to connect to the network, and terminate if the CPE device is successfully connected to the network. If the CPE device fails to connect to the network, it is judged whether the number of restarts of the CPE device meets the preset number, and if so, a variable period is adopted to retry the network connection; wherein N≥1.

[0070] The CPE device includes a line switching connection module, which is used for the CPE device to connect to another high-availability server. If the network is successfully connected, it is determined to be a server failure and a failure alarm notification is issued.
