Detailed Description
A detailed description will be given below of a specific embodiment of a control device for an electric apparatus according to an embodiment of the present invention with reference to the drawings. It should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a control apparatus for an electric device, as shown in fig. 1, which may include: a control module 10, a first power supply 41, a processing module 20, a second power supply 42, and a transmission module 30;
the first power supply 41 is connected to the control module 10, and is configured to supply power to the control module 10, where a power supply voltage of the first power supply 41 is a first voltage V1;
the second power supply 42 is connected to the processing module 20, and is configured to supply power to the processing module 20, where a power supply voltage of the second power supply 42 is a second voltage V2; wherein the second voltage V2 is greater than the first voltage V1;
the transmission module 30 is connected to the signal input ki of the control module 10 through a first interface j 1;
the transmission module 30 is connected to the signal output end do of the processing module 20 through a second interface j2, and is configured to receive a first signal S1 which is sent by the processing module 20 and carries the second voltage V2;
the transmission module 30 is connected to a ground GND through a third interface j 3;
the transmission module 30 is further configured to: when the first signal S1 is a low level signal, transmitting a ground signal provided by the ground GND to the control module 10; when the first signal S1 is a high-level signal and the voltage corresponding to the high-level signal is the second voltage V2, the voltage of the first interface j1 is converted into the first voltage V1, so that the control module 10 determines a signal (e.g., S1') corresponding to the first signal S1 according to the ground signal GND and the first voltage V1.
In fig. 1, "S1 (V2)" indicates a first signal carrying the second voltage, and "S1' (V1)" indicates a signal carrying the first voltage and corresponding to the first signal.
Therefore, through the arrangement of the transmission module, even if the control module and the processing module adopt different driving voltages, normal work of the control module and the processing module can still be ensured, and the selection range is effectively widened on the selection of the processing module and the control module.
It should be emphasized that, when the first voltage is less than the second voltage and the processing module sends a signal to the control module, the transmission module converts the high-voltage signal into a low-voltage signal, so as to prevent the high-voltage signal from burning out the interface of the signal input end of the control module, thereby preventing the control module from being damaged and improving the safety and reliability of the control device.
In practical applications, the first voltage may be greater than the second voltage, and the low-voltage signal received by the control module does not need to be converted, but is directly transmitted to the control module.
Therefore, the role of the transmission module can be understood as:
but simply converts the voltage carried in the received signal while leaving the other information carried in the signal unchanged.
In the embodiments of the present invention, the following description is made based on the first voltage being smaller than the second voltage.
It should also be noted that, alternatively, the driving voltages of the transmission module and the processing module (i.e., the power supply voltages provided by the first power supply and the second power supply) may be different (not shown) in addition to being the same (as shown in fig. 1), as long as the control module and the processing module can normally operate under the driving of different voltages through the transmission module, and whether the transmission module and the processing module use the same driving voltage is not limited in the embodiment of the present invention.

In fig. 1, S2(V1) "indicates a second signal carrying a first voltage, and" S2' (V2) "indicates a signal carrying a second voltage and corresponding to the second signal.
Therefore, through the transmission module, the second signal transmitted by the control module can be transmitted to the processing module, and meanwhile, the voltage carried by the signal received by the processing module can be the second voltage, so that the requirement of a voltage platform corresponding to the processing module is met, the processing module can process the received signal, and the information interaction is favorably realized.
Optionally, in this embodiment of the present invention, as shown in fig. 2, the transmission module 30 includes: a first conversion unit 31 and a second conversion unit 32;

the second conversion unit 32 is connected to the signal input terminal ki of the control module 10 through the first interface j1, connected to the signal output terminal do of the processing module 20 through the second interface j2, and connected to the ground terminal GND through the third interface j3, where the second conversion unit 32 is configured to:
when the first signal S1 is a low level signal, transmitting a ground signal provided by the ground GND to the control module 10; when the first signal S1 is a high-level signal and the voltage corresponding to the high-level signal is the second voltage V2, the voltage of the first interface j1 is converted into the first voltage V1, so that the control module 10 determines the signal S1' corresponding to the first signal S1 according to the ground signal GND and the first voltage V1.
Wherein the function of the first conversion unit can be understood as: the function of the second conversion unit, which converts low voltage to high voltage, can be understood as: conversion of high pressure to low pressure.
Therefore, through the arrangement of the first conversion unit and the second conversion unit, the conversion of the voltage of the signal can be realized, and the control module and the processing module can normally work under different driving voltages.
Optionally, in an embodiment of the present invention, as shown in fig. 2, the first conversion unit 31 includes: a voltage conversion circuit 311.

the first interface j1 and the first power supply 41 are both electrically connected to the anode of the diode D, and the cathode of the diode D is electrically connected to the source of the transistor MOS.
Therefore, the function and the effect of the second conversion unit can be realized through the arrangement of the transistor and the diode, and the structure of the control device is prevented from being complicated while voltage conversion and signal transmission are realized, so that the structure of the control device is simplified and the manufacturing cost of the control device is reduced on the basis that the control module and the processing module adopt different driving voltages.
Of course, in the embodiment of the present invention, the specific structure of the second conversion unit is not limited to that shown in fig. 2, and other structures capable of implementing the function of the second conversion unit may also be adopted, and is not limited herein.
Optionally, in an embodiment of the present invention, as shown in fig. 2, the second converting unit 32 further includes: a first pull-up resistor R1 and a second pull-up resistor R2;

By arranging the second pull-up resistor, when the transistor is conducted, the second power supply can be prevented from being directly grounded and short-circuited, so that the second power supply is protected; when the transistor is turned off, the second voltage can be transmitted to the cathode of the diode, so that the control module can acquire a signal corresponding to the first signal.
Optionally, in an embodiment of the present invention, as shown in fig. 2, the second converting unit 32 includes: a second capacitance C2;
the second capacitor C2 is located between the second interface j2 and the gate of the transistor MOS.
The capacitance value of the second capacitor may be, but is not limited to, a picofarad level.
Therefore, the signal output by the processing module can be filtered through the second capacitor, the interference of the signal is reduced, and the effectiveness of the transmitted signal is improved.
It should be noted that, optionally, in the embodiment of the present invention, a signal transmitted between the processing module and the control module may be a high-frequency signal, and at this time, the first capacitor and the second capacitor may also be used to filter a low-frequency signal, so as to improve accuracy and effectiveness of the signal.
The operation of the first conversion unit and the second conversion unit is exemplified below.
As shown in fig. 2, it is assumed that the first voltage supplied by the first power supply 41 is 3.3V and the second voltage supplied by the second power supply 42 is 5V.
1. For the first conversion unit:
when the control module 10 outputs the second signal S2 of 3.3V, the first converting unit 31 increases the voltage to 5V through the voltage converting circuit 311, obtains and outputs a signal S2 'of 5V corresponding to the second signal S2, so that the processing module 20 receives the signal S2' of 5V.
2. For the second conversion unit:
assuming that the first signal S1 is a digital signal and is 10, when the processing module 20 outputs the first signal S1 of 5V:
if "1" is input to the gate of the transistor MOS (i.e. high level, the voltage corresponding to the high level may be 5V):
since the transistor MOS is a P-type transistor, the transistor MOS is in an off state at this time, and under the condition that a loop is not formed, a current passes through the second pull-up resistor R2, so that the potential of the cathode of the diode D is 5V; because the electric potential of the anode of the diode D is 3.3V, the electric potential of the anode of the diode D is smaller than that of the cathode at the moment, so that the diode D is cut off; moreover, since the first power supply 41, the first pull-up resistor R1 and the signal input terminal ki do not form a loop, the potential of the signal input terminal ki of the control module 10 is 3.3V, and therefore the signal input terminal ki of the control module 10 detects a high level (1);
if "0" (i.e., low level) is input to the gate of the transistor MOS:
since the transistor MOS is a P-type transistor, the transistor MOS is in a conducting state at this time, the second power supply 42 can be prevented from being directly grounded by the second pull-up resistor R2, and the voltage of 5V can act on the second pull-up resistor R2, and the ground signal provided by the ground terminal GND is transmitted to the cathode of the diode D, so that the potential of the cathode of the diode D is close to 0V; the potential of the anode of the diode D is 3.3V, and the potential of the anode of the diode D is larger than that of the cathode at the moment, so that the diode D is conducted; moreover, since a voltage of 3.3V acts on the first pull-up resistor R1, the potential of the signal input terminal ki of the control module 10 is pulled down to a low level (noted as 0), and since there is a small voltage drop in the diode D, and the voltage drop is generally 0.3V to 0.7V, the potential of the signal input terminal ki of the control module 10 is about 0.3V to 0.7V;
therefore, the signal input terminal ki of the control module 10 receives the digital signal 10, which is different from the voltage of the first signal before processing, so that the information interaction between the control module 10 and the processing module 20 is realized.
Optionally, in an embodiment of the present invention, N1 signal output ends, N2 signal input ends, N1 and N2 are all integers greater than 1, and N1 is greater than or equal to N2, the signal output ends, the fourth interfaces, and the fifth interfaces of the control module are arranged in a one-to-one correspondence with the first conversion units, and the signal input ends of the processing module are arranged in a one-to-one correspondence with at least some of the fifth interfaces;
of the N1 signal outputs of the control module: at least part of the output second signals are of different kinds.
For example, taking fig. 3 as an example, the signal output terminals of the control module 10 have three signals, which are respectively denoted as ko1, ko2 and ko3, wherein the signal output terminal ko1 is used for outputting the data signal sd1, the signal output terminal ko2 is used for outputting the clock signal ck, and the signal output terminal ko3 is used for outputting the chip selection signal cs;
the signal input terminals of the processing module 20 have three signal input terminals, which are denoted as di1, di2 and di3, respectively, the signal input terminal di1 is configured to receive the data signal sd1 subjected to the voltage conversion processing, the signal input terminal di2 is configured to receive the clock signal ck subjected to the voltage conversion processing, and the signal input terminal di3 is configured to receive the chip selection signal cs' subjected to the voltage conversion processing;
at this time, the number of the first conversion units is three, and the first conversion unit positioned at the uppermost position in the drawing is denoted as 31a, the first conversion unit positioned at the middle position in the drawing is denoted as 31b, and the first conversion unit positioned at the lowermost position in the drawing is denoted as 31 c; the uppermost first switch unit 31a is electrically connected to the signal output terminal ko1 through the corresponding fourth interface j4, and is electrically connected to the signal input terminal di1 through the corresponding fifth interface j5, the middle first switch unit 31b is electrically connected to the signal output terminal ko2 through the corresponding fourth interface j4, and is electrically connected to the signal input terminal di2 through the corresponding fifth interface j5, and the lowermost first switch unit 31c is electrically connected to the signal output terminal ko3 through the corresponding fourth interface j4, and is electrically connected to the signal input terminal di3 through the corresponding fifth interface j 5.
That is, in fig. 3, the signal output terminal of the control module 10, the fourth interface, the fifth interface, the first conversion unit, and the signal input terminal of the processing module 20 are disposed in a one-to-one correspondence.
Of course, in practical situations, the arrangement of the control module, the fourth interface, the fifth interface, the first conversion unit and the processing module is not limited to that shown in fig. 3, and the description is only given by taking the example shown in fig. 3 as an example.
So, when control module need export multiple signal, can export respectively through each signal output part to transmit to each first conversion unit through the fourth interface that corresponds, so that each first conversion unit handles the back to various signals, and the corresponding fifth interface of rethread transmits respectively, thereby can realize the simultaneous transmission of multiple signal, can also avoid appearing disturbing between the multiple signal of simultaneous transmission.
Optionally, in the embodiment of the present invention, M processing modules are provided, where M is an integer greater than 1;
the signal output end of each processing module is connected with the second conversion unit;
the kind of the second signal includes: chip selection signals and non-chip selection signals, wherein the number of the chip selection signals is M, and M is less than N1;
the N2 signal inputs of each processing module include: a chip select input and a non-chip select input;
the chip selection input end of each processing module corresponds to and is connected with each first conversion unit used for processing the chip selection signal;
the first conversion unit for processing the non-chip selection signal is connected with the non-chip selection input end of each processing module.
For the control module, when the processing module needing data interaction is selected from the processing modules, a chip selection signal can be sent to the selected processing module, and no chip selection signal is sent to other processing modules.
Therefore, through the arrangement of the structure, when the control module needs to perform information interaction with a certain processing module, the control module can perform information interaction with the processing module through controlling the chip selection signal, and meanwhile, other processing modules are guaranteed to temporarily stop performing information interaction with the control module at the moment, so that the control module can perform information interaction with the processing modules in sequence to achieve the purpose of polling the processing modules.
Moreover, when one processing module is abnormal, the abnormal processing module does not influence the interaction process of the control module and other processing modules through the arrangement of the structure, so that the safety and the reliability of the control device are improved.
For example, as shown in fig. 4, the types of the second signal output by the control module 10 may include: taking two processing modules as p1 and p2 as an example, the data signal (denoted as sd1), the clock signal (denoted as ck), and the chip select signal (denoted as cs) may have two, denoted as cs1 and cs 2;
accordingly, four signal output terminals of the control module 10 may be provided, which are respectively denoted as ko1, ko2, ko3 and ko 4; the first conversion unit is provided with four, which are respectively denoted as 31a, 31b, 31c and 31d, the signal input terminal of the processing module may be provided with three, the signal input terminal for receiving the processed data signal sd1 'is denoted as di1, the signal input terminal for receiving the processed clock signal ck' is denoted as di2, and the signal input terminal for receiving the processed chip select signal (such as cs1 'or cs 2') is denoted as di 3; then:
the signal output end ko1 is configured to output a data signal sd1, where the data signal sd1 is transmitted to the first conversion unit 31a through the corresponding fourth interface j4, and after the first conversion unit 31a performs conversion processing on the data signal sd1, the processed data signal sd 1' is transmitted to the signal input ends di1 of the processing module p1 and the processing module p2 through the corresponding fifth interface j5, respectively;
the signal output end ko2 is configured to output a clock signal ck, where the clock signal ck is transmitted to the first conversion unit 31b through the corresponding fourth interface j4, and after the first conversion unit 31b performs conversion processing on the clock signal ck, the processed clock signal ck' is transmitted to the signal input ends di2 of the processing module p1 and the processing module p2 through the corresponding fifth interface j5, respectively;
the signal output end ko3 is configured to output a chip selection signal cs1, the chip selection signal cs1 is transmitted to the first conversion unit 31c through the corresponding fourth interface j4, and after the first conversion unit 31c performs conversion processing on the chip selection signal cs1, the processed chip selection signal cs 1' is transmitted to the signal input end di3 of the processing module p1 through the corresponding fifth interface j 5;

Thus, when the control module 10 needs to send data to the processing module p1, the chip selection signal cs1 is turned on, and the chip selection signal cs2 is turned off, and when the processing module p1 receives the processed chip selection signal cs1 ', the processed data signal sd1 ' and the clock signal ck ' are received;

also, the control module may receive a data output signal (e.g., 00100110, represented by sd 2) from the processing module.
Therefore, information interaction between the control module and the processing module can be realized in the valid period of the chip selection signal.
