It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
The method for detecting the reason of the disconnection of the monitoring terminal comprises the following steps: the detection terminal monitors the power supply condition of a first power supply of the detection terminal, sends fault test data to the monitoring terminal at a first preset frequency, and sends network disconnection test data to the server at a second preset frequency in a first network connection mode.

Because the invention adopts the detection terminal to detect the reason of the disconnection of the monitoring terminal on the basis of the existing monitoring system, the configuration related to the detection terminal is needed before the detection of the reason of the disconnection of the monitoring terminal. The configuration related to the detection terminal can be completed by adopting a special configuration client in the monitoring system, and the main configuration part is as follows: 1. and configuring all monitoring terminals associated with the detection terminal, such as a fixed camera, a PTZ (pan/tilt/zoom) camera, a DVR/NVR (analog/digital recording) and other monitoring terminals by using the configuration client. 2. And configuring network parameters of the detection terminal, such as network IP, a subnet, a gateway, a port and the like by using the configuration client, and configuring a second network connection mode with the server.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Example 1
Fig. 1 is a system architecture diagram illustrating a method for detecting a reason for a dropped connection of a monitoring terminal according to embodiment 1 of the present invention, which only shows relevant parts related to this embodiment for convenience of description, and the following details are described below:
referring to fig. 1, the system is composed of a server 11, a detection terminal 12 and a monitoring terminal 13.
The detection terminal 12 is configured to monitor a power supply condition of a first power supply of the detection terminal, send fault test data to the monitoring terminal 13 at a first preset frequency, and send network disconnection test data to the server 11 at a second preset frequency through a first network connection manner.
The first power supply is a power supply for the detection terminal 12 during normal operation, and in practical situations, the detection terminal 12 is generally powered by commercial power. The second power supply corresponding to the first power supply is a standby power supply which is started when the first power supply is powered off, so that the detection terminal 12 cannot be immediately stopped due to the power off of the first power supply, and power supplies such as a super capacitor can be used as the second power supply. The first preset frequency and the second preset frequency can be set by a technician according to actual conditions, and if the first preset frequency and the second preset frequency are both set to be 10hz, the fault test data and the network disconnection test data are sent once by the detection terminal 12 every 0.1 second.
The first network connection mode is a network connection mode of the detection terminal 12 and the server 11 when the monitoring system is operating normally.
In order to ensure the accuracy of detecting the reason of the disconnection of the monitoring terminal 13, the detection terminal 12 and the monitoring terminal 13 are arranged in the same local area network and the same power supply network, the same power supply network means that the detection terminal 12 and the monitoring terminal 13 both adopt a first power supply source for supplying power, and at the moment, when the disconnection of the monitoring terminal 13 is detected due to the power failure of the monitoring terminal 13, the detection terminal 12 detects the power supply condition of the detection terminal 12. And the first preset frequency and the second preset frequency are respectively used for sending fault test data and network disconnection test data to the monitoring terminal 13 and the server 11, so that the monitoring terminal 13 and the server 11 can generate corresponding fault loopback data and network disconnection test data according to the received test data and send the fault loopback data and the network disconnection test data to the detection terminal 12 in real time, and the purpose of detecting the network connection states of the detection terminal 12 and the monitoring terminal 13 as well as the detection terminal 12 and the server 11 is achieved.
Further, if the power supply condition of the first power supply is power off, the second power supply is started to supply power to the detection terminal 12, so that the detection terminal 12 can normally send the power off information of the monitoring terminal 13.
In this embodiment, the detecting terminal 12 has a standby second power supply, and performs emergency power supply on the detecting terminal 12 when the detecting terminal 12 is powered off, so as to ensure that the detecting terminal 12 can normally send information of the power failure of the monitoring terminal 13 to the server 11.
In the system, the monitoring terminal 13 is configured to receive fault test data, generate corresponding fault loopback data according to the fault test data, and send the fault loopback data to the detection terminal 12, where the detection terminal 12 and the monitoring terminal 13 are in the same local area network and the same power supply network.
The corresponding fault loopback data is generated according to the fault test data, and various generation modes can be adopted, for example, the fault loopback data can be generated by adding a fixed verification code after the fault test data.
In the system, the server 11 is configured to receive the network disconnection test data, generate corresponding network disconnection packet data according to the network disconnection test data, and send the network disconnection packet data to the detection terminal 12.
The same method can be adopted to generate corresponding network-breaking packet data according to the network-breaking test data, and fixed verification codes are added after the network-breaking test data to generate the network-breaking packet data.
In the system, the detection terminal 12 is further configured to determine a reason for the disconnection of the monitoring terminal 13 according to a power supply condition of the first power supply, a reception condition of the fault packet data and the network disconnection packet data, and send the reason to the server 11.
Judging the reason for the disconnection of the monitoring terminal 13, and sending the reason to the server 11, wherein the method comprises the following steps:
if the power supply condition of the first power supply is power failure, judging that the reason for the disconnection of the monitoring terminal 13 is power failure of the monitoring terminal 13;
if the fault return packet data is not received within the first preset time, judging that the reason of the disconnection of the monitoring terminal 13 is the fault of the monitoring terminal 13;
if the network disconnection return packet data is not received within the second preset time, it is determined that the reason for the disconnection of the monitoring terminal 13 is that the network of the monitoring terminal 13 is disconnected.
The sending of the information of the network disconnection of the monitoring terminal 13 to the server 11 includes:
the detection terminal 12 starts a second network connection mode to send the information of the network disconnection of the monitoring terminal to the server 11.
The relationship between the first preset time and the first preset frequency and the relationship between the second preset time and the second preset frequency must satisfy:
the first preset time is greater than or equal to a period corresponding to the first preset frequency;
the second preset time is greater than or equal to a period corresponding to the second preset frequency.
Since the server 11 and the monitoring terminal 13 both return the corresponding network disconnection test data and the corresponding network disconnection return packet data to the detection terminal 12 in real time after receiving the network disconnection test data and the fault test data, the detection terminal 12 receives the fault return packet data at the first preset frequency and receives the network disconnection return packet data at the second preset frequency under the condition that the network connection state is normal, but when the network connection with the server 11 and the monitoring terminal 13 is disconnected, the detection terminal 12 cannot normally receive the fault return packet data and the network disconnection return packet data. In this case, in the present embodiment, it is preferable to determine the network connection state between the detection terminal 12 and the server 11 and between the detection terminal 13 by using a method of determining disconnection if the packet data is not received within a predetermined time. The first preset time and the second preset time can be selected by technicians according to actual needs, but the first preset time and the second preset time are necessarily greater than a period corresponding to the first preset frequency and a period corresponding to the second preset frequency, if the first preset time and the second preset time are less than one period, the packet data are not normally sent to the detection terminal 12, the detection terminal 12 cannot normally judge the network connection state, if the first preset time and the second preset time are 10 hertz, the first preset time and the second preset time can be selected to be 1 second, namely, when the packet data of the disconnected network and the packet data of the failed network are not received within 1 second, the detection terminal 12, the server 11 and the monitoring terminal 13 are judged to be disconnected.
In practical situations, when the monitoring system is constructed, the first network connection mode of the detection terminal 12 and the server 11 when the monitoring system is operating normally is predetermined, so that the detection terminal 12 and the server 11 can communicate when operating normally. Since the detecting terminal 12 and the monitoring terminal 13 are in the same lan, the first network connection mode is the network connection mode between the monitoring terminal 13 and the server 11 when the monitoring terminal operates normally. In order to enable the detection terminal 12 to normally send the information of the network disconnection of the monitoring terminal 13 to the server 11 under the condition that the first network connection mode cannot be used, when the detection terminal 12 is disconnected from the server 11, a standby second network connection mode is started to transmit the information of the network disconnection of the monitoring terminal 13, wherein the second network connection mode can select any network connection mode different from the first network connection mode.
In this embodiment, since the detection terminal 12 and the monitoring terminal 13 are in the same lan, and when the detection terminal 12 and the server 11 are disconnected, the monitoring terminal 13 and the server 11 are also in the disconnected state at the same time, so that when it is detected that the detection terminal 12 does not receive the network disconnection packet data within the second preset time, and it is determined that the detection terminal 12 and the server 11 are disconnected, it may be determined that the network disconnection between the monitoring terminal 13 and the server 11 is caused, that is, the reason for the line disconnection of the monitoring terminal 13 is the network disconnection of the monitoring terminal 13. Because the detection terminal 12 and the server 11 are in the disconnected state at this time, the disconnected information of the monitoring terminal 13 cannot be sent to the server 11 through the normal first network connection mode, and when the wireless network is selected as the second network connection mode, the wireless network communication mode that wifi and the like can be accessed to the wide area network can be preferably used. When the monitoring terminal 13 fails, the network connection cannot be normally performed, so that when it is detected that the network disconnection return packet data is not received within the second preset time, it can be determined that the reason for the disconnection of the monitoring terminal 13 is the failure of the monitoring terminal 13.
In the system, the server 11 sends the reason for the disconnection of the monitoring terminal to the video operation and maintenance terminal for displaying after receiving the reason for the disconnection of the monitoring terminal. The user can inquire the reason of the disconnection of the monitoring terminal at the video operation and maintenance terminal and display and view the reason through the video operation and maintenance terminal.

If the Internet of things detection equipment does not receive the network disconnection packet data within 1 second continuously, the reason that the video monitoring terminal is disconnected is judged.
In S206, the internet of things detection device sends the reason for the disconnection of the video monitoring terminal to the central management server.
The internet of things detection equipment sends the reason of the video monitoring terminal that the video monitoring terminal is disconnected to the central management server after judging the reason of the video monitoring terminal that the video monitoring terminal is disconnected, if the reason of the video monitoring terminal that the video monitoring terminal is disconnected is the reason of the internet of things detection equipment, the internet of things detection equipment is also disconnected from the central management server, the information of the monitoring terminal that the internet of things detection equipment is disconnected cannot be sent through the optical fiber, and at the moment, the standby wifi wireless network is started to send the information of the video monitoring terminal that the internet of things is disconnected to the central. When the video monitoring terminal is powered off due to the reason that the video monitoring terminal is disconnected, the super capacitor supplies power to the Internet of things detection equipment, so that the Internet of things detection equipment can work for a period of time and can send power-off information to the central management server.
And after receiving the reason of the disconnection of the video monitoring terminal, the central management server sends the reason of the disconnection of the video monitoring terminal to the video operation and maintenance terminal for displaying.
