Abstract

The present invention relates to a method for quickly switching monitoring equipment when changing lines. The method is to set a connection detection device on an Ethernet switch. When a device connected to the Ethernet switch is disconnected from the original connection port and connected to another connection port of the Ethernet switch, the connection detection device can clear the connection address of the original connection and restart the detection of the connection address of another connection port to apply to the device, so that the other connection port is connected to the device again. In this way, the Ethernet road does not need to pause for a period of time when the device position is changed.

Description

A method for quickly switching monitoring equipment when changing lines

technical field

The present invention provides a method for quickly switching monitoring equipment when changing lines, especially using a connection detection device that can clear the connection address, and can restart detecting the connection address of another connection port and is applied to the device , so that the Ethernet switch can continue to operate when the location of the device is changed, without stopping and waiting.

Background technique

The traditional equipment (such as: computer, generator, etc.) is changed in the way that the equipment needs to change the original connection position between the equipment and an Ethernet switch (or Ethernet router) due to its system reset or on-site maintenance. When connecting to another location, the switch must wait for a long time to confirm that the device is not in the original location, then clear the previously memorized address, and re-apply the connection address of another connection port.

However, when the Ethernet switch waits, the signal connected to the Ethernet switch will be interrupted. In this way, in addition to having to wait for the time for the Ethernet switch to reapply a new address, the work of the device will be caused. Pausing makes the user feel very inconvenient and increases the overall cost of use. Therefore, if a method that can quickly switch the Ethernet switch when changing lines can be invented, the Ethernet switch can be quickly switched without waiting for a period of time, so as to shorten the idle time of the equipment. It is the direction that the relevant industry needs to work on urgently.

Contents of the invention

In view of the fact that the known method of changing the line of the equipment will cause the Ethernet switch to stop for a long time, which will seriously affect the lack of work of the equipment, the present invention provides a method for quickly switching the monitoring equipment when changing the line. The method is to install a connection detection device on the Ethernet switch, so that a device connected to the Ethernet switch is switched from the original connection port to another connection port of the Ethernet switch. , the connection detection device can clear the connection address of the original connection, and re-detect the connection address of another connection port and apply it to the device, so that the other connection port can be connected to the device again, so that the device can Continuous operation, without the purpose of stopping for a period of time due to changing the position of the equipment.

Detailed ways

Based on the previous technology, the line change method of the equipment at the Ethernet switch must be stopped, which will cause the work of the equipment to stop and seriously affect the continuity of the equipment. The present invention provides a monitoring device when changing lines. The method of fast switching, please refer to Fig. 1, shown in Fig. 2, this method is to be provided with a connection detection device 11 in this Ethernet switch 10, make a device connected with this Ethernet switch 10 through Ethernet 30 20. When switching from the connection port 13 of the original connection to another connection port 15 of the Ethernet switch 10, use the connection detection device 11 to quickly clear the connection address of the original connection, and start to detect another connection again. The connection address of one connection port 15 is applied to the device 20, so that the other connection port 15 is connected to the device 20 again, so that when the Ethernet switch 10 changes the position of the device 20, it can continue to operate without stopping a period of time.

In the present invention, please refer to FIG. 1 and FIG. 2 , the Ethernet switch 10 is provided with a processor 16 so that the processor 16 can control the operation of the link detection device 11 .

In the present invention, as shown in FIG. 1, the Ethernet switch 10 is provided with a switch controller 17, and the switch controller 17 is connected to at least one communication interface 18, and the communication interfaces 18 are connected via the Ethernet network. 30 is connected with equipment 20 and electronic device 40 (such as: computer), so that the Ethernet switch 10 can transmit the data of monitoring equipment 20 to the electronic device 40 via Ethernet 30 .

In the present invention, referring to FIG. 1, the Ethernet switch 10 also includes a read-only memory 19 (ROM) (such as: flash read-only memory) and a random access memory 110 (RAM) (such as: synchronous dynamic random access memory), these read-only memories 19 and random access memory 110 are respectively connected to the processor 16, so that the processor 16 can temporarily store the processed data in the random access memory 110 to Time-sharing multitasking is used to process data, and the processed data to be stored can be stored in the read-only memory 19 .

In the present invention, please refer to FIG. 1, the Ethernet switch 10 has at least one communication interface 18, and the communication interface 18 can be a fiber converter or a twisted pair connector (RJ45).

In the present invention, as shown in FIG. 3, when the Ethernet switch 10 changes the position of the device 20, it will be processed according to the following steps:

Step 301: First, determine whether the device 20 is switched from the original connection port 13 to another connection port 15 of the Ethernet switch 10, (that is, the potential of the connection port 13 changes from High potential 1 to is LOW potential 0); if yes, perform the following steps; otherwise, repeat step 301;

Step 302: If the potential of the connection port 13 changes from High potential 1 to LOW potential, the processor 16 controls the connection detection device 11 to clear the original connection address of the connection port 13;

Step 303: If it is detected that the device 20 is switched to communicate with another connection port 15 of the Ethernet switch 10 (that is, the potential of the other connection port 15 changes from LOW potential 0 to High potential 1) , then the processor 16 controls the connection detection device 11 to apply the detected connection address of the other connection port 15 to the device 20, so that the other connection port 15 is connected to the device 20 again, so that the Ethernet When the network switch 10 changes the position of the device 20, it can continue to operate without stopping for a period of time.
