Short-wave four-channel integrated channel machine

Abstract

The invention provides a short-wave four-channel integrated channel machine which comprises a receiving channel module, a photoelectric conversion module, a channel digital signal processing module, a business digital signal processing module, a frequency synthesizer module, a main control module, a front panel module, a power module, a CPCI bus, and a CPCI expansion slot. Four kinds of reception and a business control channel are integrated, so as to realize the advantages that: the quantity and the volume of equipment are reduced; the weight is saved; since the main control module employs the CPCI bus to communicate with eah CPCI module, the bus transmission rate is high and the anti interference performance is good; at the same time, since the data transmission between the short-wave four-channel integrated channel machine and the transmitter is carried out through the optical fiber, the transmission rate is high, and the broadband data is supported in addition to the original narrowband data; and the optical cable transmission is used so that the anti interference performance of the information transmission is good.

Description

technical field [0001] The invention relates to the field of short-wave communication systems, and in particular relates to a short-wave four-channel integrated channel machine. Background technique [0002] In the past, receivers and controllers could only realize the reception or service control function of a single channel. To realize the reception and service control functions of four channels, multiple receiver units and controller unit drawers are required, which are large in number and large in size. It is also heavy. At the same time, the controller and the transmitter are generally only connected by an audio cable, which has disadvantages such as low transmission rate and poor anti-interference effect. Contents of the invention [0003] The purpose of the present invention is to provide a short-wave four-channel integrated channel machine, which can be used as a multi-functional controller and receiver, realizes the integration of four receiving and service contr...
