Problems solved by technology

In this way, the copyright of the upper computer software is not well protected, and the interests of the manufacturer of the upper computer software have been affected.
Some manufacturers also use their own customized protocol, which increases the burden of software modification
Moreover, the upper computer software and the lower computer software need to be modified at the same time, and it is not universal
Different types of host computer software correspond to different protocols, which is a heavy burden on R&D personnel and is not conducive to code maintenance

Embodiment Construction

[0031] It should be noted that, in the case of no conflict, the following technical solutions and technical features can be combined with each other.

[0032] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0033] A receiver detection method, such as figure 1 shown, including:

[0034] Step S1, connecting the upper computer software to the receiver through communication, and the upper computer software sends a request command to the receiver;

[0035] Step S2, the receiver receives and sends the encryption protocol to the host computer software according to the request instruction;

[0036] Step S3, the host computer software receives and analyzes the encrypted protocol, and outputs the analysis result.

[0037] This embodiment takes the receiver as a GNSS receiver for specific description. This embodiment is applied to the field of GNSS navigation, especially when it is necessary to avoid pirated ...

Abstract

The invention relates to the pirate detection field, especially to a detection method of a receiver. Therefore, while modification on authorized-edition receiver software and upper computer software is reduced, the cracking difficulty for authorized-edition upper computer software usage by the pirate receiver increases, so that the copyright of the upper computer software can be protected well and the piracy behavior can be cracked down and thus the legal rights of the manufacturer can be protected.

Description

technical field [0001] The invention relates to the field of piracy detection, in particular to a receiver detection method. Background technique [0002] With the development of modern science and technology, receivers are widely used in detection integration, aerial remote sensing, mobile 3D and so on. Many product forms are produced in the form of combined use of receivers and host computer software. For example, GNSS receivers generally follow the NMEA0183 protocol, Novatek protocol, RTCM protocol, etc. Therefore, receivers from different manufacturers can use the same host computer software without any processing. In this way, the copyright of the upper computer software is not well protected, and the interests of the manufacturer of the upper computer software have been affected. Some manufacturers also use their own customized protocols, which increases the burden of software modification. Moreover, the software of the upper computer and the software of the lower c...
