Title (EN) DISEQC DEVICE AND TRANSMITTING AND RECEIVING CIRCUIT THEREOF
(FR) DISPOSITIF DISEQC ET SON CIRCUIT DE TRANSMISSION ET DE RÉCEPTION
(ZH) 一种DiSEqC设备及其发送接收电路
Abstract:
(EN) A DiSEqC device and a transmitting and receiving circuit thereof. The transmitting and receiving circuit comprises: a switch control module, a switch module, an LC resonance module, a signal conversion module and a shaping module. When a set-top box sends a control signal, the switch control module controls the switch module so that same is turned off or on according to the control signal, and the set-top box outputs a control signal to an controlled end correspondingly through the LC resonance module or the switch module according to the switch module being turned off or on; and when the set-top box receives a feedback signal of the controlled end, current-voltage conversion is performed on the feedback signal via the signal conversion module after which a corresponding AC voltage signal is output to the shaping module, and the shaping module performs reverse shaping on the AC voltage signal and then outputs a square wave level signal to the set-top box, and the set-top box receives feedback information about the controlled end.
(FR) L'invention concerne un dispositif DiSEqC et son circuit de transmission et de réception. Le circuit de transmission et de réception comprend : un module de commande de commutation, un module de commutation, un module de résonance LC, un module de conversion de signal et un module de mise en forme. Lorsqu'un boîtier décodeur envoie un signal de commande, le module de commande de commutation commande le module de commutation de telle sorte que celui-ci est arrêté ou mis en marche en fonction du signal de commande, et le boîtier décodeur délivre un signal de commande à une extrémité commandée de manière correspondante à travers le module de résonance LC ou le module de commutation selon que le module de commutation est éteint ou mis en marche ; et lorsque le boîtier décodeur reçoit un signal de rétroaction de l'extrémité commandée, une conversion courant-tension est effectuée sur le signal de rétroaction par l'intermédiaire du module de conversion de signal après quoi un signal de tension alternative correspondant est délivré au module de mise en forme, et le module de mise en forme effectue une mise en forme inverse sur le signal de tension alternative et délivre ensuite un signal de niveau d'onde carrée au boîtier décodeur, et le boîtier décodeur reçoit des informations de rétroaction concernant l'extrémité commandée.
(ZH) 一种DiSEqC设备及其发送接收电路,包括:开关控制模块、开关模块、LC谐振模块、信号转换模块和整形模块;当机顶盒发送控制信号时,由开关控制模块根据所述控制信号控制开关模块关断或导通,机顶盒根据开关模块的关断或导通对应通过LC谐振模块或开关模块向被控端输出控制信号;当机顶盒接收被控端的反馈信号时,反馈信号经信号转换模块进行电流电压转换后输出相应的交流电压信号至整形模块,由整形模块对所述交流电压信号进行反向整形后输出方波电平信号至机顶盒,机顶盒接收被控端的反馈信息。
