Embodiment 1

[0014] Such as figure 1 As shown, an IO multiplexing port includes a first driver amplifier U1 and a second driver amplifier U2. The first driver amplifier U1 and the second driver amplifier U2 are connected in parallel between the port and the internal circuit. The input end of the amplifier U1 is connected to the port, the output end is connected to the internal circuit, the input end of the second drive amplifier U2 is connected to the internal circuit, and the output end is connected to the port. In this circuit, the relay J2 is the main switch that controls the LED light control circuit. After the relay J2 controls the LED light control circuit to be disconnected, when the first drive amplifier U1 is activated and the second amplifier U2 is turned off, the port is connected to the internal circuit. The port is the input port; when the first driving amplifier U2 is turned off and the second driving amplifier U2 is turned on, the internal circuit is connected to the port, and...

Embodiment 2

[0016] Such as figure 2 As shown, in this embodiment, on the basis of embodiment 1, the power supply circuits of the first driving amplifier U1 and the second driving amplifier U2 are respectively provided with a PMOS tube Q1 and a PMOS tube Q2, namely, the first driving amplifier U1 and the second driving amplifier U1. The negative pole of the power supply of the driving amplifier U2 is grounded, the positive pole of the power supply of the first driving amplifier U1 is connected to the power supply through the PMOS tube Q1, and the positive pole of the power supply of the second driving amplifier U2 is connected to the power supply through the PMOS tube Q2. The first driving amplifier U1 is controlled by the PMOS tube Q1, and the second driving amplifier U2 is controlled by the PMOS tube Q2, which facilitates the conversion of port input and output.

[0017] The gates of the above-mentioned PMOS transistor Q1 and PMOS transistor Q2 are connected to a controller, and the PMOS tr...

Embodiment 3

[0019] Such as image 3 As shown, in this embodiment on the basis of embodiment 2, an NMOS tube Q3 is provided between the power negative pole of the first drive amplifier U1 and the ground, and an NMOS tube Q3 is provided between the power negative pole of the second drive amplifier U2 and the ground. The gates of tube Q4, NMOS tube Q3 and NMOS tube Q4 are also connected to the controller, and a field effect tube is set at the ground, that is, the power supply of the first driving amplifier U1 can be controlled by PMOS tubes Q1 and NMOS Q3, PMOS tubes Q1 and NMOS Q3 When one is damaged, it does not affect the use of the entire device. At the same time, the power supply of the second drive amplifier U2 can be controlled by the PMOS transistors Q2 and NMOS Q4. When one of Q2 and Q4 is damaged, it does not affect the use of the entire device.

Abstract

The invention discloses an IO multiplexing port comprising a first drive amplifier U1 and a second drive amplifier U2, wherein the first drive amplifier U1 and the second drive amplifier U2 are in parallel connection between a port and an internal circuit. The IO multiplexing port further comprises an LED lamp control circuit comprising an NMOS tube Q3 and an NMOS tube Q4. The IO multiplexing port has the advantages that an electric appliance port is converted into an input and output port, the size of an electric appliance is reduced, and use is facilitated. A control circuit is additionally arranged on the IO port, an LED lamp can be connected with the IO port, and the control circuit can control the brightness of the LED lamp, so that the IO port can be multiplex. The IO multiplexing port can serve as an input port and an output port of electronic equipment, and the LED lamp can be connected with the IO port for convenient overhaul when the electronic equipment breaks down.

Description

Technical field [0001] The present invention relates to a multiplexing port, in particular to an IO multiplexing port. Background technique [0002] The input and output of many existing devices are divided into two ports, which increases the volume of the device, and the two ports need to be inserted into the input and output respectively, which is inconvenient to use. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and deficiencies of the prior art, and provide an IO multiplexing port to solve the defects of the existing dual-port (that is, input and output ports) of devices that are too large and inconvenient to use. [0004] The object of the present invention is achieved through the following technical solutions: an IO multiplexing port, including a first drive amplifier U1 and a second drive amplifier U2, the first drive amplifier U1 and the second drive amplifier U2 are connected in parallel at the port an...
