The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The present application is described in detail below with reference to the accompanying drawings and implementation methods.

[0025] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of the first embodiment of the cooperative control circuit board of the present application. In this embodiment, the cooperative control circuit board 10 includes: a circuit substrate 11, a first communication interface 12 and a second communication interface 13.

[0026] Among them, a cooperative control circuit board 10 provided in the present application is specifically used in electronic devices that need to expand the functions of the main control circuit board 101 to meet new functional requirements, such as any reasonable household appliances such as air conditioners, washing machines or refrigerators. By adding a cooperative control circuit board 10 to the old version or the household appliances that have been installed and used, it is connected to the original main control circuit board 101, so that the cooperative control circuit board 10 can be effectively used to expand the functions of the main control circuit board 101, and there is no need to change the original design and circuit structure of the main control circuit board 101. Of course, in other embodiments, the cooperative control circuit board 10 can also be specifically used in any other reasonable electronic devices such as CNC machine tools, electronic mechanical arms or electric toys to add functions to the electronic equipment, and this embodiment does not limit this.

[0027] Specifically, the circuit substrate 11 can be understood as a circuit core board that integrates various circuit elements, conductive circuits and insulating packaging layers to achieve designed electrical functions.

[0028] Furthermore, at least a portion of circuit elements and conductive lines for realizing the newly added functions are correspondingly embedded or attached in the circuit substrate 11 to form a first functional circuit 111 .

[0029] Furthermore, the first communication interface 12 is arranged on the circuit substrate 11 for coupling to the external main control circuit board 101, that is, a signal processing central circuit board for realizing the originally designed electrical function; and the second communication interface 13 is also correspondingly arranged on the circuit substrate 11, and is used to couple to the controlled circuit 102 of the main control circuit board 101, that is, the controlled circuit 102 elements and conductive lines for realizing the originally designed electrical function of the main control circuit board 101.

[0030] Among them, the first communication interface 12 is specifically communicated with the second communication interface 13, so that the main control circuit board 101 is coupled to the controlled circuit 102 through the cooperative control circuit board 10 to ensure that the realization of the original design electrical function is not affected, and the first functional circuit 111 in the cooperative control circuit board 10 can also be used to add and expand the electrical function.

[0031] In addition, the term "coupled" herein refers to any direct and indirect connection means. Therefore, if the first circuit is described as being coupled to the second circuit, it means that the first circuit can be directly connected to the second circuit through electrical connection or signal connection methods such as wireless transmission, optical transmission, etc., or can be indirectly connected to the second circuit through other circuits or connection means.

[0032] According to the above scheme, when the main control circuit board 101 has insufficient resources such as interfaces, connection pins and wiring, the first functional circuit 111 can be set in the auxiliary control circuit board 10 without changing the original design and circuit structure of the main control circuit board 101, so as to effectively expand the circuit of the main control circuit board 101 without affecting the original function and installation and use of the main control circuit board 101, so that functions can be added to the corresponding electronic equipment more conveniently and time-savingly, and the implementation cost is also relatively low.

[0033] In one embodiment, some circuit elements are specifically buried or attached in the circuit substrate 11, such as a chip, an MCU (Micro Control Unit) circuit or a single-chip microcomputer, or any other reasonable circuit and conductive line with a signal processing function, to form a signal processing circuit 112, so that the signal processing circuit 112 can be used to perform partial signal processing, thereby effectively reducing the control calculation load of the main control circuit board 101.

[0034] The signal processing circuit 112 is coupled to the first functional circuit 111, the first communication interface 12 and the second communication interface 13, so that the controlled circuit 102 is connected to the main control circuit board 101 through the second communication interface 13, the signal processing circuit 112 and the first functional circuit 111.

[0035] In one embodiment, the main control circuit board 101 is specifically connected to the controlled circuit 102 through a set communication interface, and the first communication interface 12 and the second communication interface 13 are of the same interface type and are the same as the set communication interface, so that when the function of the main control circuit board 101 needs to be expanded, the original controlled circuit 102 can be directly removed from the main control circuit board 101, and after the first functional circuit 111 is added to the auxiliary control circuit board 10, the first communication interface 12 of the auxiliary control circuit board 10 is connected to the set communication interface, and the second communication interface 13 is connected to the controlled circuit 102, so that the main The control circuit board 101 controls or collects data for the first functional circuit 111 on the auxiliary control circuit board 10 by communicating with the auxiliary control circuit board 10, and the original controlled circuit 102 can also communicate with the main control circuit board 101 with the help of the forwarding of the auxiliary control circuit board 10 without affecting the control and function realization of the controlled circuit 102; and compared with updating the design of the main control circuit board 101, or welding circuit elements and conductive lines corresponding to the new functions on the main control circuit board 101, it is obviously more convenient and time-saving to implement through the interface plug-in method, and the implementation cost is also lower, and the risk of damage to the corresponding electronic equipment is avoided.

[0036] Optionally, the first communication interface 12 and the second communication interface 13 have the same interface type, and specifically can be any reasonable interface type such as a UART (Universal Asynchronous Receiver Transmitter) interface or a SPI (Serial Peripheral Interface) interface, and this application does not limit this.

[0037] See also Figure 2 , Figure 2 The difference between the cooperative control circuit board in this embodiment and the first embodiment of the cooperative control circuit board provided in this application is that the cooperative control circuit board 20 further includes a third communication interface 24 .

[0038] Specifically, the third communication interface 24 is arranged on the circuit substrate 21 and coupled to the signal processing circuit 212, and the third communication interface 24 is used to connect to an external program burning circuit, and the signal processing circuit 212 also specifically corresponds to a programmable control circuit, so that the signal processing circuit 212 and / or the main control circuit board 101 can be updated and iterated through the program burning circuit to meet the program control needs of the new functions.

[0039] In another embodiment, the signal processing circuit 212 may not be a programmable control circuit, and the third communication interface 24 may be used to connect to the second functional circuit, so as to further expand the function of the main control circuit board 101 to meet more functional requirements, or be reserved for subsequent direct functional expansion without the need to set up the auxiliary control circuit board 20 again, or be reserved for users to download and / or upload data information.

[0040] Furthermore, in one embodiment, the circuit substrate 21 is also specifically provided with a gating circuit, which couples the signal processing circuit 212, the second communication interface 23 and the third communication interface 24, that is, the second communication interface 23 and the third communication interface 24 are specifically connected to the signal processing circuit 212 through the gating circuit, and the gating circuit can trigger the connection between different internal paths thereof to selectively connect the second communication interface 23 with the signal processing circuit 212, or connect the third communication interface 24 with the signal processing circuit 212, so that the main control circuit board 101 and / or the signal processing circuit 212 can selectively control the controlled circuit 102, or realize signal interaction with the program burning circuit or the second functional circuit to realize the corresponding function.

[0041] Optionally, the number of the third communication interfaces 24 is any reasonable number such as 1, 2 or 5, and this application does not limit this.

[0042] Optionally, the signal processing circuit 212 supports at least two different communication protocols to facilitate signal interaction with different circuits to achieve more functions, which is not limited in the present application.

[0043] Optionally, the interface type of the first communication interface 22 is the same as that of the second communication interface 23 , and is the same as or different from that of the third communication interface 24 , which is not limited in the present application.

[0044] In one embodiment, the circuit substrate 21 is further provided with a wireless communication circuit, which is coupled to the signal processing circuit 212 and is used to realize communication connection with an external host computer so as to feedback data information in the main control circuit board 101 and / or the signal processing circuit 212 and upload it to the host computer, thereby facilitating data analysis and / or status monitoring in the background, and can also receive command control from the host computer to control the signal of the main control circuit board 101 and / or the auxiliary control circuit board 20.

[0045] Optionally, the first functional circuit 211 may specifically include one or more of any reasonable circuit elements or devices such as a light-emitting device, a temperature sensor, and a key reader, and one or more of any reasonable circuit elements or devices such as a light-emitting device, a temperature sensor, and a key reader are coupled to the signal processing circuit 212, and the present application does not limit this.

[0046] For ease of understanding, the main control circuit board 101 is specifically applied in air-conditioning equipment, and new functions such as temperature collection and button reading need to be added to the air-conditioning equipment. For example, it can be seen that in order to avoid directly replacing the main control circuit board 101, the WiFi (wireless network communication technology) module connected to the serial port of the main control circuit board 101 can be removed, and an auxiliary control circuit board 20 can be added, which is connected to the air-conditioning control board, that is, the main control circuit board 101, and a temperature sensor and an LED light are added to the auxiliary control circuit board 20, and connected to the auxiliary control circuit board 20, and the WiFi module removed before is also connected to the auxiliary control circuit board 20.

[0047] Among them, the auxiliary control circuit board 20 will periodically send temperature data to the main control circuit board 101. When the LED needs to be controlled, the main control circuit board 101 sends a command to the auxiliary control circuit board 20. After analysis, the LED is turned on or off; and the communication of the WiFi module will be directly forwarded to the main control circuit board 101 after being judged by the auxiliary control circuit board 20.

[0048] It can be seen that by installing a light-emitting device, a temperature sensor and a key reader on the circuit substrate 21 in the auxiliary control circuit board 20, the data is processed by the signal processing circuit 212 in the auxiliary control circuit board 20, and actively sent to the main control circuit board 101, and function control instructions are output, such as LED (Light Emitting Diode) control, motor control, etc., and the main control circuit board 101 sends commands to the auxiliary control circuit board 20, so that the auxiliary control circuit board 20 can control the output.

[0049] Among them, for the communication with the original controlled circuit 102, the cooperative control circuit board 20 does not need to perform any processing, but directly forwards the sent / received data to the main control circuit board 101, thereby being able to effectively expand the circuit function without changing the original electrical design of the main control circuit board 101, without affecting the original function, and also reducing the control calculation load of the main control circuit board 101.

[0050] It is understandable that, in this embodiment, the circuit substrate 21, the first communication interface 22, the first functional circuit 211, the signal processing circuit 212 and the second communication interface 23 are respectively the same as the circuit substrate 11, the first communication interface 12, the first functional circuit 111, the signal processing circuit 112 and the second communication interface 13.

[0054] Specifically, the signal processing circuit in the assistant control circuit board receives the instruction control data sent by the external main control circuit board.

[0055] S32: Sending the command control data to the first functional circuit or the controlled circuit of the main control circuit board in response to the data type of the command control data.

[0056] It is understandable that the data types of the instruction control data used by the main control circuit board to control the first functional circuit and the controlled circuit respectively can be different, or include different characteristic information, such as characters or additional information, so as to facilitate the control of different controlled targets.

[0057] Specifically, when the signal processing circuit receives the instruction control data sent by the main control circuit board, the instruction control data is first detected to determine the data type or characteristic information of the instruction control data, and the instruction control data is sent to the first functional circuit or the controlled circuit according to the data type or characteristic information, so as to more conveniently control the first functional circuit or the controlled circuit.

[0058] Similarly, when the signal processing circuit receives data information sent by the first functional circuit or the controlled circuit or any other reasonable circuit or the host computer, it can first detect the data information and directly parse it in response to the data type and / or characteristics of the data information, or forward the data information to the main control circuit board.
