An electrical stimulation system and a method of controlling electrical stimulation. The electrical stimulation system comprises an electrical stimulation unit, a sensing unit for detecting one of the circuit signals of the electrical stimulation unit a signal receiving unit for receiving a plurality of loop signals of the sensing unit a signal identification unit, Converted to a time series signal, when the time series signal has a specific interrupt signal and a specific recovery signal, then trigger a mode adjustment signal in a control module control module at least a preset control database, the model control database Comprising a plurality of preset modes each including a preset interrupt signal and a preset resume signal, and when a specific interrupt signal and a specific recovery signal are respectively the same as the preset interrupt signal and the preset resume signal, a mode adjustment command is outputted Actuating the module and switching the electrical stimulation unit to its current output intensity according to the mode adjustment instruction.一種電刺激系統與電刺激模式的控制方法,電刺激系統包含一電刺激單元,一感測單元用以偵測電刺激單元之一迴路訊號;一訊號接收單元係用以接收感測單元之複數個迴路訊號;一訊號辨識單元,將迴路訊號轉換為一時間序列訊號,當時間序列訊號具有一特定中斷訊號與一特定恢復訊號,則觸發一模式調整訊號於一控制模組;控制模組至少預設有一模式對照資料庫,模式對照資料庫包含有複數個預設模式,各包含一預設中斷訊號與一預設恢復訊號,當特定中斷訊號與特定恢復訊號分別與預設中斷訊號及預設恢復訊號相同,則輸出一模式調整指令於致動模組,並依據模式調整指令使電刺激單元切換其電流輸出模式。100‧‧‧電刺激系統20‧‧‧電刺激單元20A‧‧‧第一電極20B‧‧‧第二電極10‧‧‧感測單元201‧‧‧迴路訊號30‧‧‧訊號接收單元40‧‧‧訊號辨識單元201’‧‧‧時間序列訊號T‧‧‧特定中斷訊號F‧‧‧特定恢復訊號M0‧‧‧模式調整訊號50‧‧‧控制模組60‧‧‧致動模組501‧‧‧模式對照資料庫SM1、SM2‧‧‧預設模式ST1、ST2‧‧‧預設中斷訊號SF1、SF2、SF2’‧‧‧預設恢復訊號M1‧‧‧模式調整指令70‧‧‧電流調整元件
