Abstract

The invention discloses a digital duplex remote networking wired interphone and relates to the technical field of interphones. The digital duplex remote networking wired interphone comprises master equipment (11), a controller area network (CAN) bus line concentration controller (22) and slave equipment (33), wherein the master equipment (11) is connected with the CAN bus line concentration controller (22); the slave equipment (33) is connected with intelligent nodes which are distributed at all logging well holes; and the intelligent nodes are connected with the CAN bus line concentration controller (22) through CAN bus communication interfaces and cables. By adoption of the digital duplex remote networking wired interphone, real-time voice communication between an operator in a well logging vehicle and staff on a well can be realized. The digital duplex remote networking wired interphone has a voice communication protocol at a security level, can stably operate under the severe working condition, and has the characteristics of water-proof, moisture-proof and dust-proof performance, wide working temperature range, and the like.

Description

Technical field: [0001] The invention relates to the technical field of communication equipment, in particular to a digital duplex remote networking wired walkie-talkie. Background technique: [0002] There are various electrical appliances, machinery, and hydraulic equipment in the well testing vehicle, so the electromagnetic environment is complex and the operating space is limited. When the oil field well testing vehicle is performing measurement operations, the operator on the well logging vehicle and the wellhead staff need to communicate with each other in real time to obtain the status of the well operation at any time to ensure the safety of the operation. When the analog wired walkie-talkie is used in this environment, it is easy to have a tail sound and generate harsh noise after the call is over. Therefore, high requirements are put forward for the safety and reliability of the voice communication system. Invention content: [0003] The object of the present in...
