In terms of comprehensive, the recognition unit includes comparator, mu balanced circuit, and the comparator is generated according to two input values One output valve, and transmitting to the mu balanced circuit so that the mu balanced circuit identification is fitted to the plug-in module in pedestal, two Individual input value be respectively the value that state machine sends to comparator and node N1 at partial pressure value.

So that increasing the evident characteristics of three-terminal voltage-stabilizing switch U1 in the case of the difference of voltage type is inapparent (such as, 5V can not exactly be recognized with the supply of 6V voltages by the first control unit).It should be appreciated that for each plug-in module 3 The identification of voltage type mainly according to variable resistance R2 determining, according further to knowable to foregoing relationships, to voltage type Identification also receives the impact of the resistance distribution of resistance R1, R4 and R3, therefore for the technician, select suitable resistance or Resistance magnitude is difficult, can exactly be recognized by first control unit by way of the present embodiment.On the other hand, If being only supplied to the electric power of plug-in module 3 by the voltage VCC of power circuit, can be by taking to the voltage at node N1, N2 Sample carries out voltage stabilizing using three-terminal voltage-stabilizing switch U1, to guarantee that circuit stability works.

In addition, control board 22 further comprises state machine U3, sampling voltage Vref according to mu balanced circuit is configured to To change power circuit voltage VCC.In certain embodiments, pass after three-terminal voltage-stabilizing switch U1 samples sampling voltage Vref State machine U3 is passed, thus, state machine U3 can be by logical with selectivity to the partial circuit element in the second control unit internal circuit Disconnected mode is adjusted to voltage VCC, for example partial pressure/transformation.
