Heading machine vehicle-mounted network and testing method thereof

Abstract

The invention relates to a heading machine vehicle-mounted network and a testing method thereof. The heading machine vehicle-mounted network comprises a distributed communication system main body arranged on a heading machine and an optical fiber connected with an external dispatching room for signal transmission, and the optical fiber is wound and unwound along with the heading machine through an optical fiber coil capable of automatically winding and unwinding; the distributed communication system main body comprises an upper-layer main body and a lower-layer main body; the whole system moves forwards along with shield tunneling, and the problem of frequent disassembly in communication in the past is solved; the invention further provides a testing method of the heading machine vehicle-mounted network, and the field intensity coverage quality and the service quality under different vehicle-mounted network configuration modes can be accurately evaluated.

Description

technical field [0001] The invention relates to the field of roadheader communication devices, in particular to a roadheader vehicle-mounted network and a testing method thereof. Background technique [0002] With the development of large-scale underground rail transit, higher requirements are put forward for the management of the job site, such as video surveillance, vehicle management, and personnel management. It brings great convenience to management: accurate location information; through accurate location information, you can quickly check the working location of construction personnel and improve the efficiency of location management. The assignment of tasks is scientific; according to the location information of personnel, the assignment is more reasonable and scientific. Management visualization; personnel can know the specific location in real time during operation, item loading, and construction, track production progress, and visualize management. [0003] Exis...

Problems solved by technology

The typical application of RFID for personnel positioning comes from the expansion of the personnel attendance system. It mainly identifies whether personnel exist in a certain area, and it cannot be tracked in real time, and there is no standard network system for positioning applications. Therefore, the network establishment cost and establishment more difficult

[0004] Chinese invention patent CN212572979U discloses a smart tunnel safety construction management system based on UWB wireless technology, including a platform client, a server connected to the platform client through a network cable, and The first switch that is connected to the server through a network cable; the first switch is connected to a number of second switches through an optical fiber transceiver, and each second switch is connected to a corresponding UWB base station through a network cable; set on wristbands, safety helmets and vehicles There are positioning tags that match with the UWB base station; there is a management center in the server, and the management center is respectively connected to the platform client and the first switch; it uses UWB wireless technology to realize the positioning of personnel and vehicles during underground tunnel construction. Accurate positioning, and alarms for various risk sources, improve the safety of the construction site, can manage the tunnel construction site uniformly and efficiently, improve positioning accuracy, integrate system resources, simplify configuration, and improve management efficiency, but still There are the following disadvantages: the positioning module needs to be installed additionally, and with the forward movement of the shield tunneling, the positioning module and its matching communication module need to be moved synchronously; the existing network cable structure is single, once the fiber breaks, it will bring instability to the system etc.
