Problems solved by technology

[0005] The purpose of the present invention is to provide a reconnection method and monitoring equipment to solve the problem that when the IP address of the remote equipment changes, the monitoring equipment reconnects with the remote equipment, and the administrator must log in to the background of the monitoring equipment to modify the saved records. The IP address of the remote device in the network, which consumes a long time and wastes manpower

Embodiment 1

[0050] Embodiment 1. Assuming that the monitoring device has two channels, respectively the first channel and the second channel, the first channel is connected to the first remote device, and the IP address of the first remote device connected to the first channel saved by the monitoring device is 192.168.1.101, the MAC address is 8A:47:01:54:89:11; the second channel is connected to the second remote device, and the IP address of the second remote device connected to the second channel saved by the monitoring device is 192.168.1.102 , the MAC address is 8A:47:01:54:89:22;

[0051] The first channel is disconnected from the first remote device, and the second channel is connected to the second remote device. The monitoring device obtains the IP address of the first remote device as 192.168.1.109 and the MAC address as 8A:47:01 :54:89:11; The obtained IP address of the second remote device is 192.168.1.102, and the MAC address is 8A:47:01:54:89:22;

[0052] The monitoring dev...

Embodiment 2

[0064] Embodiment 2. A reconnection connection process provided by the embodiment of the present invention, such as figure 2 Shown:

[0065] Step 201, the monitoring device sends a broadcast message to search for remote devices on the network;

[0066] Step 202, the monitoring device receives a remote device feedback message, the feedback message includes IP address, MAC address, port number, etc., the monitoring device records these information and generates a list of remote devices, as shown in Table 1:

Abstract

The invention discloses a reconnection method and a monitoring device, comprising: the monitoring device obtains the first IP address and the first MAC address recorded by the remote device, if the obtained first MAC address is the same as the second MAC address currently saved by itself The address is the same, and the obtained first IP address is different from the second IP address currently saved by itself, the monitoring device modifies the second IP address to the first IP address, and the monitoring device uses the first IP address to convert the reconnecting the channel of the monitoring device to the remote device. When the IP address of the remote device changes, the monitoring device actively modifies the second IP address saved by the monitoring device to the first IP address, which realizes automatic reconnection between the monitoring device and the remote device, thereby The administrator does not need to log in to the background of the monitoring device to modify the IP address of the remote device in the saved record, which avoids the waste of time and manpower.

Description

technical field [0001] The invention relates to the monitoring field, in particular to a reconnection method and monitoring equipment. Background technique [0002] The video surveillance system is an important part of the security system, and it is a comprehensive system with strong prevention capabilities, which is widely used in various occasions, such as airports and scenic spots. With the continuous development of modern science and technology, video surveillance has entered the network era and has been paid more and more attention by people. [0003] In the existing video monitoring system, the monitoring device uses the IP address to connect to the remote device. If the remote device connected to the monitoring device reassigns the IP address or the administrator If the IP address is manually modified, the monitoring device will be disconnected because it cannot connect to the IP address of the remote device. If you want to reconnect, the administrator must log in to...
