Description
Technical field
The utility model relates to technical field of micro communication, particularly one list cable combination switch system.
Background technology
At Europe and north America region, along with growing satellite television subscribers is to the requirement of content of multimedia and HDTV (High-Definition Television) ease for use, the digital video recorder of satellite high definition receiver and multi-tuner (DVR) is used widely in family.In traditional direct broadcasting satellite (DBS) is installed, in the face of being equipped with the satellite receiver of multiple high-frequency tuner or multiple satellite receiver, in order to make DBS outdoor unit (ODU, out-door Unit) be connected with these tuners, need many independently cables, this scheme considerably increases the complexity of installation, the cable laying cost that also cost is very high simultaneously.Therefore, start the peripheral device occurring so-called 22KHz ConvertBox, V/H switch enclosure, power splitter, circumscribed DC power supply, combination switch and digital satellite equipment control etc. on the market, object is all complexity in order to simplify installation and reduces cable laying cost.
Fig. 1 is the schematic diagram that traditional use combination switch carries out direct broadcasting satellite reception, and Fig. 2 is the schematic diagram that traditional use list cable switch carries out direct broadcasting satellite reception.Fig. 3 is the structural representation of traditional combination switch; Fig. 4 is the structural representation of traditional single cable switch; No matter use combination switch or single cable switch, it is all single satellite reception solution, and that is combination switch and the connected mode of single cable switch in traditional direct broadcasting satellite receives adhere to the different occupation mode of two classes separately.If pre-receiving direct broadcasting satellite signal, satellite receiver first sets satellite band wavestrip and the receiving parameter of pre-receiving, then by control signals such as DC power supply, satellite band wavestrip and receiving parameter via cable cochain to outdoor high-frequency tuner.Outdoor high-frequency tuner is set up in teledish, and according to uploading the control signals such as DC power supply, satellite band wavestrip and receiving parameter via cable, to complete the direct broadcasting satellite signal of frequency range wavestrip after frequency reducing via chain under cable to satellite receiver.
In traditional direct broadcasting satellite reception programme, user will receive direct broadcasting satellite signal at least needs outdoor unit and indoor unit, wherein outdoor unit comprises antenna, high-frequency tuner, cable, 22KHz switch or V/H switch and power splitter etc., and indoor unit comprises cable, satellite receiver and television set.More than can only be applicable to sole user, if when multiple user wants to use outdoor installation simultaneously, just need to add combination switch and power splitter etc. in addition, the object that multiple user uses outdoor high-frequency tuner simultaneously could be realized like this.
Existing combination switch product major part still uses multiple high-frequency tuner to share one group of power bus circuit, this design connects a combination switch only having a satellite receiver, when supplying again plural high-frequency tuner simultaneously, electric hypodynamic phenomenon will be there is, cause user to be connected to want the direct broadcasting satellite frequency range wavestrip received.Simultaneously owing to sharing one group of power bus circuit, if there is a user to have selected H.H (18V/22KHz) frequency range in multiple user, will make other user use L.V (13V/0KHz) or L.H (18V/0KHz) frequency range time cannot normal received signal.More there is the existing combination switch product of part, in order to eliminate above-mentioned interference problem, filtering 22KHz this Tone control signal on power bus circuit, although solve interference problem, but cause all users all cannot select the frequency range of H.V (13V/22KHz), H.H (18V/22KHz), create other problem.In addition, owing to being the circuit using resolution element design, except configuration complexity, between circuit, also easily produce that high-frequency signal disturbs mutually, isolation between frequency range is not enough, thus cause the signal that receives bad, to such an extent as to cannot rating.
In single cable switch, the same with combination switch have portioned product filtering 22KHz this Tone control signal in supply line, because DiSEqC control signal is also formed by 22KHz signal madulation, also be just equivalent to filter DiSEqC signal, cause digital satellite equipment to control cannot normally select frequency range wavestrip.Existing single cable switch is all combined by the digital satellite equipment control circuit in switch matrix circuit and product, therefore the port of serial connection function only can be left in the outside of product, for wanting to use combination switch to for the user selecting high-frequency tuner, they are the frequency ranges (L.V, L.H, H.V, H.H) that cannot receive, select via extra port high-frequency tuner.
The power circuit that modern satellite receiver inside uses all adopts switch mode power supply circuit, therefore on power bus except original 22KHz Tone and DiSEqC control signal, can seal in the continuation periodic signal that a switch mode power supply circuit produces, its frequency is about 50KHz-200KHz.If without good frequency range/polarization discriminator circuit, no matter be that the continuation periodic signal that combination switch or single cable switch all can produce because of this switch mode power supply circuit causes misoperation.
