Referring to fig. 5 to 7, the control circuit board 22 in the first embodiment includes:

a power circuit configured to realize the power path conversion of the base 1 to the plug-in module 3. Generally, the power path conversion means the conversion of a power voltage, for example, the power voltage is reduced from 220V ac to 12V dc, and may also mean the conversion of an original path in the base 1 for the functional circuit of some plug-in modules 3, for example, the original path is shorted by adding a bypass to the power path in the base 1 in a plug-in manner;

an identification unit coupled to the power circuit and configured to identify said power path switching and adapt the corresponding dc voltage to the plug-in module 3.

The first control part may include a sampling circuit, which is a resistor R1, R3, R4 connected to the dc voltage VCC provided by the power supply circuit, wherein the sampling circuit is connected in parallel with a voltage stabilizing circuit, which may be a three-terminal regulator U1, and the other terminal of the three-terminal regulator U1 is grounded through a resistor R and a capacitor C. One terminal of the three-terminal regulator U1 is connected to the node N1 for sampling the voltage at the node N1. The nodes N1 and N2 represent the plug interfaces between each plug module 3 and the control circuit board 22.

In addition, the voltage of the sampling circuit will change with the plugging module 3 plugging the control circuit board 22. This can be achieved by using an impedance element, such as a variable resistor R2, which, when each plug-in module 3 is coupled to the first control part, detects the voltage value Vref at the node N1 through the three-terminal regulator U1, and it should satisfy:

when the resistor R2 is connected in parallel with the resistor R4, the voltage on the sampling circuit will change, and it should be understood that, when the plug-in module 3 is not plugged in, the voltage value Vref at the node N1 should satisfy:

therefore, after the variable resistor R2 is connected to the sampling circuit in parallel, the voltage Vref value sampled by the three-terminal regulator U1 may change according to the resistance value of the resistor R2, so that the three-terminal regulator U1 can identify the voltage type of each connected plug-in module 3 by combining the corresponding relationship between the resistance value of the resistor R2 and the function circuit stored in advance. In addition, in order to make the three-terminal regulator U1 recognize the voltage type more accurately, an error comparator U2 may be connected between the sampling circuit and the three-terminal regulator U1, when the control circuit board 22 is connected to different plug-in modules 3, because the resistances of the resistors R2 in the plug-in modules 3 are different, the current in the series circuit of R1, R4, and R3 changes, and further the divided voltage value at the node N1 changes, as can be seen from fig. 5, the node N1 serves as the input end of the comparator U2, so the change of the divided voltage at the node N1 further changes the output value of the comparator U2 pointing to the three-terminal regulator U1, that is, the sampled value in the sampling circuit is fed back to the three-terminal regulator U1, and the recognition of the plug-in module 3 is completed. In summary, the identification unit includes a comparator and a voltage regulator circuit, the comparator generates an output value according to two input values, and transmits the output value to the voltage regulator circuit, so that the voltage regulator circuit identifies the plug-in module embedded in the base, and the two input values are respectively a value sent to the comparator by the state machine and a voltage division value at a node N1.

In summary, the identification unit includes a comparator and a voltage regulator circuit, the comparator generates an output value according to two input values, and transmits the output value to the voltage regulator circuit, so that the voltage regulator circuit identifies the plug-in module embedded in the base, and the two input values are a value sent to the comparator by the state machine and a voltage division value at the node N1, respectively.

So that the recognition characteristics of the three-terminal regulator U1 are increased in the case where the difference in the voltage types is not significant (such as the supply of 5V and 6V voltages cannot be accurately recognized by the first control section). It should be understood that the identification of the voltage type for each plug-in module 3 is mainly determined by the variable resistor R2, and as can be seen from the above-mentioned relation, the identification of the voltage type is also influenced by the distribution of the resistances of the resistors R1, R4 and R3, so that it is difficult for the skilled person to select the appropriate resistance value or resistance value level, which can be accurately identified by the first control unit in the manner of this embodiment. On the other hand, if power is supplied to the plug-in module 3 only through the voltage VCC of the power supply circuit, the voltage can be stabilized by the three-terminal regulator switch U1 by sampling the voltage at the nodes N1, N2 to ensure stable operation of the circuit.

In addition, the control circuit board 22 also includes a state machine U3 configured to vary the power circuit voltage VCC according to the sampled voltage Vref of the regulator circuit. In some embodiments, the sampled voltage Vref is sampled by the three-terminal regulator U1 and then transmitted to the state machine U3, so that the state machine U3 can adjust the voltage VCC by selectively switching on and off some circuit elements in the circuit in the second control portion, such as voltage division/transformation.

For each jack module 3, the variable resistor R2 is coupled to the functional circuitry therein in a manner that may be represented by nodes N3 and N4 as shown in fig. 5. The resistor R4 can be used as a protection resistor to prevent the short circuit of the sampling circuit when the variable resistor R2 is plugged.

The main circuit diagram of the second control part can refer to fig. 6. The second control unit is provided with a capacitor C1 for setting the current from the nodes N3 and N4 and a current limiting resistor R1 connected in series thereto, and supplies the functional circuits with, for example, direct current + VCC and-VCC. Wherein the current limiting resistor R1 is connected in parallel with a bidirectional switch TR1, e.g. a triac, the switch TR1 is further connected to a state machine U4, the state machine U4 is configured to generate a corresponding threshold value VTHD based on the voltage Vref for short-circuiting the switch TR1 to switch off the current limiting function when the threshold value is met.

In addition, for the dc circuit, rectifier diodes D2 and D3 with opposite polarities are provided on the paths for supplying dc + VCC and-VCC, respectively, and rectifier diodes D2 and D3 are connected to filter capacitors C3 and C4, respectively, and further grounded. A capacitor C2 is connected between nodes N3 and N4 for connecting capacitors C3, C4 and switch TR1 to ground, thereby allowing current to flow through switch TR1 to short circuit current limiting resistor R1. Thus, the voltage regulation of the functional circuit can be automatically realized. In addition, a clamping element Z4, which may be a zener diode designed in pairs, is connected to the capacitor C2 to stabilize the input current at the nodes N3 and N4.

The circuit schematic of the second control part can also refer to fig. 7, and similarly, the voltage supplied to the functional circuit can be adjusted by the capacitor C1 and the resistor R1. The rated current may be clamped by a clamping element Z4 and a resistor R2 coupled to the bidirectional switch TR 1. Preferably, a MOS switch Q1 and a state machine U5 coupled thereto are further provided, and the state machine U5 is configured to generate a corresponding threshold value VTHD according to the voltage Vref, so that the capacitor C2 is short-circuited after the voltage VCC output to the functional circuit reaches a threshold value, thereby short-circuiting and discharging the C2 through the MOS switch Q1. In addition, the on/off of the resistor R1 can be controlled by a loop formed by the switch TR1, the MOS switch Q1 and the rectifier diode D3.

In the above embodiments, the state machines U3, U4, and U5 may refer to the same device or device interface, or may be separate devices, as long as the functions of the above embodiments can be implemented, and the arrangement manner may be various. In addition, the first and second control portions may be provided in the control circuit board 22 at the same time.
