Problems solved by technology

Ordinary USB cables are convenient for data transmission, but the security does not meet the needs of special occasions. Intelligent terminals and equipment support all-in-one machines (host computers) lack identity detection and authentication processes, which cannot prevent server security risks caused by illegal terminal access to the host computer.

Embodiment Construction

[0028] A kind of communication method of improved USB interface is characterized in that comprising the following steps,

[0029] Step 1. Make an improved USB data line. The specific method is to use the 9-pin data line for USB signal transmission to form a special interface line, that is, set 4 pins of the 9-pin data line as 4 pins of the standard USB interface, and the rest The 5 pins are reserved on the data line only for grounding and not for signal and power transmission;

[0030] Step 2. Make the interface between the upper computer PC and the external interface of the required information transmission and the interface of the lower computer intelligent terminal as an interface corresponding to the improved USB data line, and match the 4 pins set in the improved USB data line 9 pins. one-to-one correspondence;

[0031] Step 3. Use the improved USB data cable to physically connect the upper computer PC with the external interface and the interface of the lower computer i...

Abstract

An improved USB interface communication method is characterized by comprising the following steps: 1, an improved USB data line is manufactured, specifically, a nine-pin data line is used for USB signal transmission, a special interface line is formed, that is, four pins in the nine-pin data line are set as four pins of a standard USB interface, and the other five pins are reserved on the data line and are only grounded without signal and power transmission; the method is simple and convenient to use, the communication safety of the equipment comprehensive guarantee and management all-in-one machine (upper computer) and the intelligent terminal (lower computer) is met, and the communication guarantee is achieved. And the confidentiality requirement of communication is met.

Description

technical field [0001] The invention is an improved communication method of the USB interface, which is used for a virtual network in which a comprehensive security management machine and an intelligent terminal communicate, so as to ensure the confidentiality of the communication. Background technique [0002] A certain type of equipment field maintenance support uses an intelligent mobile terminal for equipment comprehensive support management (smart terminal for short) as a data carrier. The field operation data is collected through the smart terminal, and the data is transmitted to the equipment support integrated machine (short for all-in-one machine) through a USB cable. Ordinary USB cables are convenient for data transmission, but the security does not meet the needs of special occasions. Intelligent terminals and equipment support all-in-one machines (host computers) lack identity detection and authentication processes, which cannot prevent server security risks cause...
