Therefore, it is in variable resistance R2 and after being connected to sample circuit, different according to the resistance of resistance R2, three-terminal voltage-stabilizing switch U1 The voltage Vref value of sampling can change, thus, the corresponding relation of the resistance R2 resistances and functional circuit for prestoring is combined, Three-terminal voltage-stabilizing switch U1 can be made to can recognize that the voltage type of each plug-in module 3 of access.In addition, in order that three end Stabilized switch U1 more accurately recognizes the voltage type, can connect error ratio between the sample circuit and three-terminal voltage-stabilizing switch U1 Compared with device U2, when control board 22 is connected with different plug-in modules 3, due to the resistance difference of resistance R2 in plug-in module 3, Hence in so that the electric current in the series circuit of R1, R4 and R3 changes, and then the partial pressure value at node N1 is occurred Change, from figure 5 it can be seen that the node N1 at the same as comparator U2 input, therefore at node N1 partial pressure change Change meeting further such that comparator U2 points to three-terminal voltage-stabilizing switchs the output valve of U1 and change, sampling that will be in sample circuit Value feeds back to three-terminal voltage-stabilizing switch U1, completes the identification of plug-in module 3.In terms of comprehensive, the recognition unit includes comparator, steady Volt circuit, the comparator generate an output valve according to two input values, and transmit to the mu balanced circuit so that described steady Volt circuit identification is fitted to plug-in module in pedestal, two input values be respectively values that above-mentioned state machine sends to comparator with Partial pressure value at node N1.

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 Partial pressure value at the individual input value value that respectively state machine is sent to comparator and node N1.

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 be recognized by the first control unit exactly with the supply of 6V voltages).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 be recognized by first control unit exactly by way of the present embodiment.On the other hand, If being only supplied to 3 electric power of plug-in module 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.

For each plug-in module 3, variable resistance R2 is coupled to functional circuit therein, and coupling mode can be by Represent according to the node N3 and N4 shown in Fig. 5.Resistance R4 can be used as protective resistance, it is to avoid occur taking in grafting variable resistance R2 The short circuit of sample circuit.
