The remote control assembly 100 of the present invention is designed in a modular manner, and integrates the bluetooth BLE function and the infrared function, i.e., it can receive the bluetooth remote control signal and the infrared remote control signal. The remote control assembly 100 is applied to an electrical appliance, such as a television, an electric fan, etc., a controller and a remote control interface are generally disposed inside the electrical appliance, the controller may include a processor, an Application-Specific Integrated Circuit (ASIC) having a control processing function, a Field Programmable Gate Array (FPGA), a single chip microcomputer, etc., and the remote control assembly 100 is mounted on the electrical appliance and connected to the remote control interface thereof to transmit a received bluetooth remote control signal and an infrared remote control signal to the controller through the remote control interface, so that the electrical appliance executes a related command operation. The remote control interface of the adopted electric appliance is an infrared remote control interface widely existing on a circuit bottom plate of the electric appliance. The remote control assembly 100 mainly comprises a bluetooth BLE module 110, an infrared module 120 and a control signal pin 10, wherein the bluetooth BLE module 110 may be modified on any type of bluetooth chip with a signal output pin for receiving bluetooth remote control signals of the smart terminal. The intelligent terminal can be a mobile phone, a tablet personal computer and the like, and is connected with the electric appliance through the Bluetooth of the Bluetooth BLE module 110 of the remote control assembly 100 for wireless communication, and at present, except for a common intelligent terminal, the intelligent remote controller is also provided with a Bluetooth module so as to send a Bluetooth control signal to the electric appliance; the remote controller refers to a special infrared remote controller matched with the electric appliance, and the infrared module 120 can be a general infrared receiving head for receiving an infrared remote control signal of the remote controller; the control signal pin 10 is disposed outside the remote control assembly 100 to connect with a controller of the electrical appliance through a remote control interface, so as to realize signal interaction between the remote control assembly 100 and the controller. In addition, the remote control assembly 100 is further externally provided with a power pin and a ground pin, wherein the ground pin is connected with the remote control interface, and the power pin is connected with the remote control interface and can share a power supply with the electric appliance controller or be additionally connected with other power supplies. The configuration of each module in the remote control assembly 100 and the contention resolution rule manner for the control command issued by the bluetooth BLE module 110 and the infrared module 120 may be various, and will be described in the following embodiments, which are not described herein.

When a first control command sent by the bluetooth BLE module 110 and a second control command sent by the infrared module 120 are received at the same time, one of the first control command and the second control command is selected according to a competition arbitration rule, if the selected first control command is the first control command, the first control command is converted into a level signal according to an infrared coding model, so that the level signal is sent to the controller through the control signal pin 10, and the controller executes the first control command; if the second control command is selected, a signal of the received second control command is sent to the controller through the control signal pin 10, so that the controller executes the second control command.

In practical application, when the intelligent terminal and the remote controller simultaneously control an electric appliance (such as a television), for example, when the intelligent terminal sends a control command of 'brightness reduction', the remote controller sends a control command of 'volume increase', the remote control assembly 100 on the electric appliance simultaneously receives and selects one of the control commands according to a competition arbitration rule, and sends the one of the control commands to the controller through the control signal pin 10 in a preset infrared code form, so that the controller executes the control command of 'brightness reduction' or 'volume increase'.

In a preferred embodiment, referring to fig. 2, the remote control assembly 100 further comprises a power pin 20 and a ground pin 30, and the remote control interface comprises a first interface, a second interface, and a third interface;
the infrared module 120 is provided with a first VDD pin 121 connected to the power pin 20 and a first GND pin 122 connected to the ground pin 30, and the bluetooth BLE module 110 is provided with a second VDD pin 111 connected to the power pin 20 and a second GND pin 112 connected to the ground pin 30;
the power pin 20 is connected to the first interface, the ground pin 30 is connected to the second interface and grounded, and the control signal pin 10 is connected to the third interface.
The power pin 20 is used for connecting a power supply, the ground pin 30 is used for grounding, the first interface, the second interface and the third interface of the infrared interface can be welding points or insertion holes, when the remote control assembly 100 is connected to the infrared interface, the power pin 20 is connected with the first interface, the ground pin 30 is connected with the second interface, the second interface is grounded, and the control signal pin 10 is connected with the third interface, so that the remote control assembly 100 transmits a level signal to the third interface through the control signal pin 10, and transmits the level signal to the controller, and the controller executes a control command.
Further, referring to fig. 2, the infrared module 120 is provided with a first signal pin 123, the bluetooth BLE module 110 is provided with a second signal pin 113, the first signal pin 123 is connected with the second signal pin 113, and a common end of the first signal pin 123 connected with the second signal pin 113 is connected with the control signal pin 10. That is, in the embodiment, the infrared module 120 and the bluetooth BLE module 110 are designed by using a "wired and" logic circuit, and besides the connection relationship, the common terminal of the first signal pin 123 connected to the second signal pin 113 is connected to the power supply pin 20 through the pull-up first resistor R1. At this time, both the bluetooth remote control signal and the infrared remote control signal are output as OD/OC signals, and when the bluetooth remote control signal or the infrared remote control signal outputs a "1" signal, a high level is formed by pulling up the first resistor R1, so that the control signal pin 10 outputs a logic level "1"; when one of the bluetooth remote control signal and the infrared remote control signal is output as a "0" signal, and the result is "0", the control signal pin 10 outputs a logic level "0". Namely, when infrared and Bluetooth are simultaneously controlled remotely, although logic conflict is caused by two control signals, physical conflict does not exist, and the device cannot be damaged under the condition.
Further, referring to fig. 3, the infrared module 120 is provided with a first signal pin 123, the bluetooth BLE module 110 is provided with a second signal pin 113, and the remote control assembly 100 further includes a multiplexer 130, wherein the multiplexer 130 is connected to the first signal pin 123, the second signal pin 113 and the control signal pin 10 respectively. The multiplexer 130, i.e. a multi-way switch, can conduct one of the infrared module 120 and the bluetooth BLE module 110 through the multiplexer 130 according to the requirement, so that the infrared remote control signal output by the infrared module 120 or the bluetooth remote control signal output by the bluetooth BLE module 110 is transmitted to the infrared interface through the control signal pin 10, and then transmitted to the controller, so that the controller executes the control command. The bluetooth BLE module 110 further includes an arbitration control signal pin 114, and the multiplexer 130 is connected to the arbitration control signal pin 114 to select one of the infrared remote control signal and the bluetooth remote control signal through the arbitration control signal pin 114.
Preferably, the multiplexer 130 may be an NPN-type transistor Q or a MOS (metal-oxide-semiconductor) field-effect transistor, in this embodiment, taking the NPN-type transistor Q as an example, when the multiplexer 130 employs the NPN-type transistor Q, referring to fig. 4, a specific connection form of the multiplexer is that the first signal pin 123 of the infrared module 120 is connected to an emitter of the NPN-type transistor Q, the first signal pin 113 of the bluetooth BLE module 110 is connected to a collector of the NPN-type transistor Q, the arbitration control signal pin 114 of the bluetooth BLE module 110 is connected to a base of the NPN-type transistor Q, and a pull-up second resistor R2 is disposed therebetween, a common end of the first signal pin 113 of the bluetooth BLE module 110 connected to the collector of the NPN-type transistor Q is connected to the control signal pin 10, and is further connected to the power supply pin 20, and a pull-up third resistor R3 is disposed therebetween.
Referring to fig. 4, specifically, when the base of the NPN type triode Q (or the gate of the MOS transistor) is "1", the NPN type triode Q (or the MOS transistor) is turned on, and the infrared remote control signal of the infrared module 120 affects the output of the control signal and is output to the control signal pin 10; when the base of the NPN type triode Q (or the gate of the MOS transistor) is "0", the NPN type triode Q (or the MOS transistor) is turned off, the infrared remote control signal of the infrared module 120 does not affect the output of the control signal, and the bluetooth remote control signal of the bluetooth BLE module 110 is output to the control signal pin 10. The above proposed asymmetric signal arbitration circuit implies the design of bluetooth remote control signal priority processing of the bluetooth BLE module 110, and the signal processing flow is as shown in fig. 4-a, after receiving a bluetooth remote control signal, the circuit (i.e., NPN-type triode Q) for transmitting an infrared remote control signal to the control signal pin 10 is closed, and then the bluetooth remote control signal is transmitted, and after finishing transmitting the bluetooth remote control signal, the circuit (i.e., NPN-type triode Q) for transmitting an infrared remote control signal to the control signal pin 10 is opened. It is easily understood that the bluetooth BLE module 110 is usually an intelligent device with a built-in software program, and the infrared module 120 is a relatively non-intelligent device, that is, the bluetooth BLE module 110 can control when its bluetooth remote control signal is output by its software program, but cannot control when the infrared remote control signal of the infrared module 120 is output, so that the signal arbitration circuit can prevent the suddenly received infrared remote control signal from interfering with the output bluetooth remote control signal.
In order to further optimize the signal control, on the basis of the above connection form, as shown in fig. 5, an infrared remote control signal detection pin 115 is further disposed on the bluetooth BLE module 110, and the infrared remote control signal detection pin 115 is connected to the first signal pin 123 of the infrared module 120 so as to detect an infrared remote control signal. Correspondingly, the signal processing flow is as shown in fig. 5-a, after receiving the bluetooth remote control signal, judging whether the infrared remote control signal is being sent, if so, caching the bluetooth remote control signal, and judging again after waiting for the infrared remote control signal to be output; if not, the multiplexer is switched to a Bluetooth remote control signal transmission path, and then a Bluetooth remote control signal is sent. That is, when detecting that there is an infrared remote control signal, bluetooth BLE module 110 may suspend output of its bluetooth remote control signal, avoid interfering with output of the infrared remote control signal.
After receiving the infrared remote control signal, judging whether the Bluetooth remote control signal is being sent, if so, continuing to send the Bluetooth remote control signal, and discarding the infrared remote control signal; if not, the multi-path selector is switched to an infrared remote control signal transmission channel, and then an infrared remote control signal is sent.
The asymmetrical alternative decision output of the Bluetooth remote control signal and the infrared remote control signal is realized in a mode of combining software and hardware.
In addition, as shown in fig. 6, an internal software program of the bluetooth BLE module 110 may be further designed to determine whether another remote control signal is being transmitted when one of the infrared remote control signal and the bluetooth remote control signal is received, if so, preferentially process the remote control signal being transmitted, and buffer the received remote control signal; if not, the received remote control signal can be sent. For the remote control signal processing flow, reference is made to fig. 6-a specifically, which will not be described herein too much. By implementing the above, it can avoid the interference to the output bluetooth remote control signal or infrared remote control signal, and can realize the delayed transmission to another infrared remote control signal or bluetooth remote control signal received midway.
Further, referring to fig. 7, a first signal pin 123 is disposed on the infrared module 120, a second signal pin 113 is disposed on the bluetooth BLE module 110, the infrared module 120 is connected to the bluetooth BLE module 110 through the first signal pin 123, and the bluetooth BLE module 110 is connected to the control signal pin 10 through the second signal pin 113. Specifically, a pin is provided on the bluetooth BLE module 110 to connect with the first signal pin 123 of the infrared module 120, and the second signal pin 113 of the bluetooth BLE module 110 is connected with the control signal pin 10. In addition, referring to fig. 7, the first VDD pin 121 and the first GND pin 122 of the infrared module 120 may also be directly connected to the bluetooth BLE module 110. In this embodiment, as shown in fig. 7-a, to implement further optimization, an internal software program and a circuit of the bluetooth BLE module 110 may be designed, so as to integrate the multiplexer in the foregoing embodiment into the bluetooth BLE chip, which may reduce the manufacturing cost. When the infrared module 120 receives the infrared remote control signal and transmits the infrared remote control signal to the bluetooth BLE module 110, the bluetooth BLE module may select the infrared remote control signal and the bluetooth remote control signal, select one of the infrared remote control signal and the bluetooth remote control signal to be output through the signal output pin of the bluetooth BLE module 110, and further transmit the selected signal to the remote control interface through the control signal pin 10, and simultaneously buffer another remote control signal that is not selected to be delayed and transmitted. Moreover, in order to further reduce the manufacturing cost, as shown in fig. 7-B, the infrared module employs an infrared diode, and the anode and the cathode of the infrared diode are connected with the bluetooth BLE module 110, and the amplification/filtering circuit thereof is correspondingly integrated inside the bluetooth BLE chip, which is a mature application technology at present and therefore will not be described in detail.
The remote control assembly 100 according to the above embodiment is connected to the remote control interface by welding or detachable connection. Specifically, when the remote control interface is a welding point, the connection between the remote control assembly 100 and the remote control interface is welding, that is, the power pin 20, the ground pin 30, and the control signal pin 10 of the remote control assembly 100 are welded to the first interface, the second interface, and the third interface, so that the connection is stable and the signal transmission is stable; when the remote control interface is the spliced eye, remote control subassembly 100 is connected for dismantling the connection with the remote control interface, can take off the infrared receiving head that originally sets up at the remote control interface to change remote control subassembly 100 cartridge to the remote control interface in, it is convenient to change.
The invention also provides a remote control method integrating Bluetooth BLE and infrared, which is used for a remote control assembly 100 integrating Bluetooth BLE and infrared, the remote control assembly 100 integrating Bluetooth BLE and infrared is applied to an electric appliance, the electric appliance is provided with a controller and a remote control interface connected with the controller, the remote control assembly 100 comprises a Bluetooth BLE module 110, an infrared module 120 and a control signal pin 10, the control signal pin 10 is connected with the controller through the remote control interface, and referring to fig. 8, the remote control method comprises the following steps:
step S100: receiving a first control command sent by the intelligent terminal and a second control command sent by the remote controller;
step S200: when the first control command or the second control command is received independently, the first control command or the second control command is sent to the controller through the control signal pin 10 in a preset infrared code mode, so that the controller executes the first control command or the second control command;
step S300: when the first control command and the second control command are received simultaneously, one of the first control command and the second control command is selected according to a competition arbitration rule and is sent to the controller through the control signal pin 10 in a preset infrared code form, so that the controller executes the first control command or the second control command.
The related remote control assembly 100 is designed in a modular mode, integrates the Bluetooth BLE function and the infrared function, and can receive Bluetooth remote control signals and infrared remote control signals. The remote control assembly 100 is applied to an electrical appliance, such as a television, an electric fan, etc., a controller and a remote control interface are generally disposed inside the electrical appliance, the controller may include a processor, an Application-Specific Integrated Circuit (ASIC) having a control processing function, a Field Programmable Gate Array (FPGA), a single chip microcomputer, etc., and the remote control assembly 100 is mounted on the electrical appliance and connected to the remote control interface thereof to transmit a received bluetooth remote control signal and an infrared remote control signal to the controller through the infrared interface, so that the electrical appliance executes a related command operation. The remote control interface of the adopted electric appliance is an infrared remote control interface widely existing on a circuit bottom plate of the electric appliance.
In this implementation step, the remote control assembly 100 receives a first control command sent by the intelligent terminal through the bluetooth BLE module 110 thereof, and receives a second control command sent by the remote controller through the infrared module 120 thereof; the intelligent terminal can be a mobile phone, a tablet personal computer and the like, and is connected with the electric appliance through the bluetooth of the bluetooth BLE module 110 of the remote control assembly 100 to perform wireless communication, and at present, except for a general intelligent terminal, the intelligent remote controller is also provided with a bluetooth module to send a bluetooth control signal to the electric appliance; the remote controller refers to a special infrared remote controller matched with the electric appliance.
When a first control command sent by the bluetooth BLE module 110 is received separately, the first control command is converted into a level signal according to the infrared coding model, so that the level signal is sent to the controller through the control signal pin 10, and the controller executes the first control command; when the second control command sent by the infrared module 120 is separately received, a signal of the received second control command is sent to the controller through the control signal pin 10, so that the controller executes the second control command. When a first control command sent by the bluetooth BLE module 110 and a second control command sent by the infrared module 120 are received at the same time, one of the first control command and the second control command is selected according to a competition arbitration rule, if the selected first control command is the first control command, the first control command is converted into a level signal according to an infrared coding model, so that the level signal is sent to the controller through the control signal pin 10, and the controller executes the first control command; if the second control command is selected, a signal of the received second control command is sent to the controller through the control signal pin 10, so that the controller executes the second control command.
The preset infrared coding model is a preset algorithm model capable of converting the control command into a level signal conforming to the infrared protocol, and may include a plurality of infrared codes, such as NEC infrared codes. The selection of the first control command or the second control command may be implemented by storing a signal arbitration control program of the infrared remote control signal and the bluetooth remote control signal in the master control chip of the bluetooth BLE module 110, including but not limited to, that is, selecting the infrared remote control signal and the bluetooth remote control signal. In practical application, when the intelligent terminal and the remote controller simultaneously control an electric appliance (such as a television), for example, when the intelligent terminal sends a control command of 'brightness reduction', the remote controller sends a control command of 'volume increase', the remote control assembly 100 on the electric appliance simultaneously receives and selects one of the control commands according to a competition arbitration rule, and sends the one of the control commands to the controller through the control signal pin 10 in a preset infrared code form, so that the controller executes the control command of 'brightness reduction' or 'volume increase'. Of course, the remote control assembly 100 may also have other configurations of the modules and signal arbitration methods, and reference may be made to the above-mentioned embodiments of the remote control assembly integrating bluetooth BLE and infrared, which will not be repeated herein.
Further, when the first control command and the second control command are received simultaneously, one of the first control command and the second control command is selected according to a competition arbitration rule, and the selected one is sent to the controller through the control signal pin 10 in a preset infrared code form, and referring to fig. 9, the remote control method further includes:
step S400: caching the unselected first control command or the unselected second control command;
step S500: after the selected first control command or second control command is sent, the first control command or second control command cached before is selected and sent to the controller through the control signal pin 10 in the form of the preset infrared code, so that the controller continues to execute.
In this implementation step, when the remote control assembly 100 receives the first control command sent by the intelligent terminal and the second control command sent by the remote controller at the same time, if one of the control commands is selected, the other control command is cached, so that the controller executes the control commands one by one, and the electrical appliances are controlled in order. With reference to the foregoing embodiments, in practical applications, when the intelligent terminal and the remote controller simultaneously operate and control an electrical appliance (such as a television), for example, the intelligent terminal sends a control command of "turning down the brightness", the remote controller sends a control command of "increasing the volume", the remote control assembly 100 on the television simultaneously receives and selects one of the commands according to the competition arbitration rule, and sends the selected command to the controller through the control signal pin 10 in the form of a preset infrared code. If the control command of 'brightness reduction' sent by the intelligent terminal is selected, the control command of 'volume increase' sent by the remote controller is cached, and after the control command of 'brightness reduction' is sent, the control command of 'volume increase' sent by the remote controller which is cached before is selected and sent to the controller through the control signal pin 10 in the form of preset infrared codes, so that the controller continues to execute the control command of 'volume increase'.
Correspondingly, if the control command of 'volume up' sent by the remote controller is selected, the control command of 'brightness down' sent by the intelligent terminal is cached, and after the control command of 'volume up' is sent, the control command of 'brightness down' sent by the intelligent terminal which is cached before is selected to be sent to the controller through the control signal pin 10 in the form of preset infrared codes, so that the controller continues to execute the control command of 'brightness down'. The above implementation details (including remote control signal processing, etc.) of the sequential cache execution between the first control command and the second control command may refer to the above contents of some embodiments of the remote control assembly integrating bluetooth BLE and infrared, and will not be repeated here.
