Device used to delay switching-on of network interface

Abstract

The invention discloses a device used to delay switching-on of a network interface. A control circuit comprises a USB power supply interface circuit; a power supply indicator lamp, a timer circuit, a signal relay circuit, a working indicator lamp, which are respectively connected with the USB power supply interface circuit. The timer circuit is connected with the signal relay circuit and the working indicator lamp, and the signal relay circuit is connected with a biconnected RJ45 network socket circuit. The network interface on-delay device is connected with a USB interface of equipment in a roll-packing workshop by a USB cable, after the equipment is electrified, the device starts to work, and a timer is used for timing, the working of the signal relay is controlled after certain time, and therefore the switching-on / off of the network interface is controlled. The device provided by the invention is advantageous in that no manual intervention is required, and after the equipment is electrified, the network is communicated automatically after the certain time, and then the own starting of the equipment and the connection of the control equipment are not affected, and at the same time, the network communication of the equipment and the normal acquisition of the data of the equipment are guaranteed.

Description

technical field [0001] The invention relates to a device for delayed connection of a network port. Background technique [0002] When there are many kinds of equipment in the packaging workshop, the industrial computer has requirements on the start-up time. For example, the industrial computer of the GD packaging machine needs to complete the startup (within 40 seconds) before the electric control cabinet sends a message. The industrial computer of some packaging machines Complete the connection of PLC and other control equipment before the HMI is started. Usually, the operating system will delay about 10 seconds to complete the startup after the network cable is plugged in, which may affect the operation of the equipment. In order to avoid situations such as unsuccessful startup of the industrial computer or unsuccessful connection of the PLC control equipment, the machine operator usually unplugs the network cable before powering on, and then plugs the network cable back i...

[0002] When there are many kinds of equipment in the packaging workshop, the industrial computer has requirements on the start-up time. For example, the industrial computer of the GD packaging machine needs to complete the startup (within 40 seconds) before the electric control cabinet sends a message. The industrial computer of some packaging machines Complete the connection of PLC and other control devices before the HMI is started. Usually, the operating system will be delayed for about 10 seconds to complete the startup after the network cable is plugged in, which may affect the operation of the device.

In order to avoid situations such as unsuccessful startup of the industrial computer or unsuccessful connection of the PLC control equipment, the machine operator usually unplugs the network cable before powering on, and then plugs the network cable back in after the equipment is fully started. A lot of work, it is easy to forget to restore the network, resulting in the loss of data collected by the machine, or abnormal program communication

At present, there is no similar product on the market to solve the above-mentioned problems in actual production. Therefore, it is very necessary to research and design a device for delayed connection of the network port to solve such problems in actual production.
