Problems solved by technology

[0002] At present, GNSS receiver (Global Navigation Satellite System, global satellite navigation system), CORS system (Continuous Operational Reference System, continuous operation reference station system) and deformation monitoring system are widely used in the field of navigation and positioning. Both CORS system and deformation monitoring system Data transmission needs to be based on the network, but in the actual situation, at least one of the following problems exists: the network fault detection and repair cannot be performed automatically, and once the network communication is interrupted, it cannot be repaired in time, which will affect the CORS system and deformation monitoring system based on the network. The proper functioning of the data transmission system

Embodiment Construction

[0052] At present, GNSS (Global Navigation Satellite System), CORS system (Continuous Operational Reference System, continuous operation reference station system) and deformation monitoring system are widely used in the field of navigation and positioning.

[0053] The CORS system has many advantages such as wide operating range, high precision, and field stand-alone operation. Usually, the CORS system consists of five reference station networks (including GNSS receivers), data centers, data transmission systems, positioning and navigation data dissemination systems, and user application systems. Each reference station is connected with the data center through the data transmission system to form a dedicated network.

[0054]The deformation monitoring system is generally composed of GNSS receiver monitoring station (including GNSS receiver), data transmission system, data monitoring center and other parts. The data of the monitoring station is transmitted to the data monitoring...

Abstract

The invention provides a GNSS receiver for executing network fault detection and restoration comprising a system control module comprising a control unit, a fault detecting unit and a reset unit; a wired network transmission module connected to the system control module, wherein the wired network transmission module is connected to a routing gateway via a network cable; a wireless network transmission module connected to the system control module; and a fault log module connected to the system control module; the fault detection unit is connected to the wired network transmission module and the wireless network transmission module, the control unit is connected to the fault detection unit and a reset unit, the reset unit is connected to the wired network transmission module, and the faultdetecting unit detects a connection state of the network cable, a communication link between the wired network transmission module and a data center, and a communication link between the wireless network transmission module and the data center, and the control unit controls the fault log module to generate reminding information according to the detection result of the fault detecting unit, and sends the reminding information to the data center.

Description

technical field [0001] The invention relates to the field of navigation and positioning, in particular to a network fault detection and repair method, a GNSS receiver and a computer-readable medium. Background technique [0002] At present, GNSS receiver (Global Navigation Satellite System, global satellite navigation system), CORS system (Continuous Operational Reference System, continuous operation reference station system) and deformation monitoring system are widely used in the field of navigation and positioning. Both CORS system and deformation monitoring system Data transmission needs to be based on the network, but in the actual situation, at least one of the following problems exists: the network fault detection and repair cannot be performed automatically, and once the network communication is interrupted, it cannot be repaired in time, which will affect the CORS system and deformation monitoring system based on the network. The normal operation of the data transmi...
