Abstract
Description
Technical Field
[0001] This utility model relates to the field of network BYPASS detection, and more specifically, to a low-cost and high-efficiency application circuit for detecting the continuity of network BYPASS. Background Technology
[0002] The BYPASS function needs to maintain network physical layer connectivity by directly connecting the two network interfaces through hardware circuitry in abnormal states such as power failure or system crash. Therefore, manufacturers need to test the BYPASS connectivity of the network before the product leaves the factory.
[0003] Existing BYPASS testing methods use integrated circuits or MCUs to write programs and add some complex logic circuits. The circuits are complex, and the integrated circuit chips or MCUs make the electronic components less substitutable, resulting in high costs and limited material versatility. Utility Model Content
[0004] To address the aforementioned shortcomings of existing technologies, a low-cost, high-efficiency BYPASS on / off detection network application circuit is provided.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a low-cost and high-efficiency detection network BYPASS connection / disconnection application circuit, including a first interface module and a second interface module. The first interface module is connected to a power module, and the negative terminal of the power module is connected to the first interface module. The second interface module includes an interface LAN2 and eight second signal lines connected to the interface LAN2. Each second signal line is connected to a corresponding light-emitting diode. The second signal line is connected to the negative terminal of the corresponding light-emitting diode, and the positive terminals of the eight light-emitting diodes are all connected to the positive terminal of the power module.
[0006] Preferably, a resistor is connected in series between the positive terminal of each light-emitting diode and the positive terminal of the power module.
[0007] Preferably, the first interface module includes an interface LAN1 and eight first signal lines connected to LAN1, wherein the interface LAN1 is connected to the negative terminal of the power module through the eight first signal lines.
[0008] Preferably, both LAN1 and LAN2 are RJ45 interfaces.
[0009] Preferably, the power supply module is a 3V DC power supply.
[0010] The beneficial effects of this utility model are as follows: By inserting the two ends of the network cable into the corresponding interfaces LAN1 and LAN2, the detection circuit forms a loop. At this time, all eight LEDs light up, indicating that the network BYPASS is normal. If any LED does not light up, it indicates that there is an abnormality in the signal line of the other lit LEDs, which needs to be checked. This detection circuit is simple, does not require integrated circuit chips or MCUs, has low cost, and the electronic components are easy to replace. It is highly versatile and can quickly detect whether there is an abnormality in the network BYPASS. It is suitable for testing whether the network BYPASSes are interconnected in batches of products in factories. Attached Figure Description

[0013] Examples of embodiments of this utility model Figure 1 As shown, a low-cost, high-efficiency BYPASS network continuity application circuit includes a first interface module and a second interface module. The first interface module is connected to a power module, and the negative terminal of the power module is connected to the first interface module. The second interface module includes an interface LAN2 and eight second signal lines connected to the interface LAN2. Each second signal line is connected to a corresponding light-emitting diode (LED). The second signal line is connected to the negative terminal of the corresponding LED, and the positive terminals of the eight LEDs are connected to the positive terminal of the power module. Preferably, the eight second signal lines are shorted through PCB wiring and connected to the positive terminal of the power supply via a series resistor in a copper foil area to achieve a low-impedance connection.
[0014] Insert the two ends of the network cable into LAN1 and LAN2 respectively, thus forming a loop in this detection circuit. If all eight LEDs light up, the network BYPASS is functioning correctly. If any LED fails to light up, it indicates an abnormality in the signal line of the other lit LEDs, requiring troubleshooting.

It can quickly detect network BYPASS abnormalities and is suitable for batch production testing in factories to ensure interoperability between network BYPASS devices.

The interface LAN1 is connected to the negative terminal of the power module through the eight first signal lines. Preferably, the eight first signal lines are also shorted through PCB wiring and connected to the negative terminal of the power supply through a copper foil area to achieve low impedance connection.
