Detailed Description
As described in the background art, at present, a remote control device is manually pressed to perform a key operation test on an electronic product such as a television, a set-top box, a network television, and the like, so as to check whether a device to be tested can normally respond. However, this approach is inefficient.
In order to solve the problems, the infrared remote control equipment comprises a switching module, a connecting module and a signal simulation module, wherein the switching module comprises a switching board, a first interface is arranged at the first end of the switching board and is coupled with a main control device, and the second end of the switching board is coupled with the signal learning module through the connecting module and can output a driving signal to the signal simulation module, and the signal simulation module can enter an infrared signal simulation mode, simulate a key value of a target remote control device and send the key value to an infrared controlled device.
In order that those skilled in the art will better understand and practice the present invention, the following detailed description is given by way of specific embodiments with reference to the accompanying drawings.
Referring to fig. 1, a schematic structural diagram of an infrared remote control device in the present invention is shown, in some embodiments of the present invention, the infrared remote control device 10 includes a switching module 11, a connection module 12, and a signal simulation module 13, where:
the adaptor module 11 includes an adaptor board 111, a first end of the adaptor board 111 is provided with a first interface 1111, the first interface 1111 is adapted to be coupled with a main control device 1A, a second end of the adaptor board 111 is coupled with the signal simulation module 13 through the connection module 12, and the adaptor module 11 is adapted to output a driving signal through the adaptor board 111 to drive the signal simulation module 13 to enter an infrared signal simulation mode;
the signal simulation module 13 is adapted to simulate a key value of the target remote control device 1B and send the key value to the infrared controlled device 1C.
In some embodiments of the present invention, the main control device 1A may be a PC.
The principle of infrared testing of the infrared remote control device 10 is described below with reference to fig. 1.
First, the first interface 1111 of the adapter board 111 is connected to the main control device 1A, and since the second end of the adapter board 111 is coupled to the signal simulation module 13 through the connection module 12, the main control device 1A may output a driving signal to the signal simulation module 13 through the adapter board 111.
After the signal simulation module 13 acquires the driving signal, under the action of the driving signal, the signal simulation module 13 may enter an infrared signal simulation mode to simulate a key value of the target remote control device 1B, and send the simulated key value to the infrared controlled device 1C, so as to perform a corresponding key value operation test on the infrared controlled device 1C.
Therefore, the switching module 11 outputs the driving signal to the signal simulation module 13 through the switching board 111, the signal simulation module 13 can enter an infrared signal simulation mode to simulate the key value of the target remote control device 1B and send the key value to the infrared controlled device 1C to be tested, and therefore, in the testing process, automatic testing can be achieved only by sending the key value to the infrared controlled device 1C, and testing efficiency can be improved.
For a better understanding and implementation by those skilled in the art, some realizable examples of the modules in the infrared remote control device testing apparatus of the present invention are shown below.
Referring to the schematic structural diagram of a signal simulation module in the present invention described in fig. 2, in some embodiments of the present invention, the signal simulation module 20 may include a main board 21, and a second interface 211, a controller 212, a signal sending end 213, and a signal sending end 214 disposed on the main board 21, where:
the second interface 211 is coupled to the second end of the adaptor module 2A through the connection module 2B, and is adapted to transmit the driving signal output by the adaptor module 2A;
the controller 212 is coupled to the second interface 211, the signal receiving terminal 213, and the signal transmitting terminal 214, and is adapted to trigger the signal receiving terminal 213 to simulate a key value and trigger the signal transmitting terminal 214 to transmit a key value in response to the driving signal;
the signal receiving terminal 213 is adapted to respond to an infrared signal sent by the target remote control device 2C and simulate a key value corresponding to the infrared signal;
the signal sending end 214 is adapted to send an infrared signal containing the key value to the infrared controlled device 2D.
The principle and process of the signal simulation module 20 simulating the target remote control device 2C will be described with reference to fig. 2 in conjunction with fig. 1.
In this embodiment of the present invention, when the signal simulation module 20 receives a driving signal from a main control device through the second interface 21, the controller 212 may respond to the driving signal, and under the action of the driving signal, the signal simulation module 20 enters an infrared signal simulation mode, the signal receiving end 213 may respond to an infrared signal sent by the target remote control device 2C and simulate a key value corresponding to the infrared signal, and the signal sending end 214 sends an infrared detection signal according to a preset key value sequence and sends the infrared signal containing the key value to the infrared controlled device 2D, and the infrared remote control device testing apparatus may detect the infrared controlled device 2D according to the key value.
In some embodiments of the present invention, the key value corresponding to the infrared signal may include a POWER key (POWER) adapted to perform a POWER on/off test on the infrared controlled device;
a return key (BACK) suitable for switching the page of the infrared controlled equipment, so that the infrared controlled equipment returns to the previous page from the current page;
a start menu key (HOME) to return the infrared controlled device to a start menu interface;
and a MUTE key (MUTE) suitable for carrying out MUTE operation on the infrared controlled equipment.
The selection-type key value may include: an ENTER key (ENTER) adapted to select a corresponding item on the menu interface;
channel selection keys, which are suitable for switching different channels, may include a last channel selection key (LEFT) and a next channel selection key (RIGHT);
volume adjusting keys, which are suitable for adjusting the volume, can comprise a volume increasing key (UP) and a volume decreasing key (DOWN);
and the function selection key (MENU) is suitable for carrying out corresponding setting on the infrared controlled equipment.
It should be noted that, in addition to the above common key values, in some other embodiments of the present invention, more key values may be included. For example, a help key, a favorites key, a pause key/play key, and a fast forward/rewind key, etc. may be included.
With reference to fig. 2, in a specific implementation, on one hand, under the action of the controller 212, the signal receiving terminal 213 may simulate a key value of the target remote control device 2C, and meanwhile, the signal sending terminal 214 may directly send an infrared signal containing the key value to the infrared controlled device 2D, so as to detect whether the infrared controlled device 2D can respond to a key operation; on the other hand, under the action of the controller 212, the signal simulation module 20 may store the key value simulated by the signal receiving terminal 213 from the target remote control device 2C, and after all the key values of the target remote control device 2C are simulated and stored, the signal transmitting terminal 214 transmits the infrared signal including the key value to the infrared controlled device 2D to detect the infrared controlled device 2D, so that the signal simulation module 20 may further include a storage unit 215, where the storage unit 214 is disposed on the main board 21, is coupled to the controller 212, and is adapted to write the operation control signal based on the key value of the controller 212 to store the key value corresponding to the infrared signal.
In a specific implementation, the controller 212 may be a single chip microcomputer, and the storage unit 215 may be built in the single chip microcomputer as a part of the single chip microcomputer.
In some embodiments of the present invention, the storage unit 215 may be an EEROM.
Because the storage unit 215 is an EEROM, the key value is learned and stored in the EEROM, and the key value can still be stored when the power is off, the key value only needs to be learned once, and repeated learning is avoided.
For the key values simulated by the signal receiving terminal 213, the controller 212 may store the key values in the storage unit 215 according to the corresponding numbers, and directly send the corresponding numbers to the infrared controlled device 2D to be tested through the signal sending terminal 214 during the testing process.
For example, the number of the power key stored in the storage unit 215 may be set to 1, the number of the mute key may be set to 2, and when the on-off test of the infrared controlled device 2D is required, 1 may be directly sent; when the mute operation needs to be performed on the infrared controlled device 2D, the step 2 is directly transmitted.
In a specific implementation, before testing a large number of infrared remote control devices 2D, one of the infrared remote control devices may be tested to check whether all key values that need to be simulated are simulated. If the key value which is not simulated exists, the corresponding key value can be simulated again in at least one of the following modes: 1) formatting the key values stored in the storage unit 215, and re-simulating all the key values to be simulated; 2) only key values that are not simulated are simulated.
When the signal receiving terminal 213 simulates all required key values and stores the key values into the storage unit 215, under the control of the controller 212, the signal simulation module 20 may sequentially and cyclically send the key values corresponding to the infrared signals to the infrared controlled device 2D by the signal sending terminal 214 according to a first-in first-out principle or a first-in last-out principle at regular intervals, until receiving an end instruction, stop sending the key values to the infrared controlled device 2D, so as to detect the infrared controlled device 2D.
It should be noted that, in a specific implementation, the simulated key values may be sent to the infrared controlled device according to any sequence until the detection of the infrared controlled device is completed.
It should be noted that before the signal simulation module 20 simulates the key value of the target remote control device 2C, the infrared transceiver of the signal simulation module 20 needs to be arranged opposite to the infrared transmitter of the target remote control device 2C, so that the two devices can communicate the infrared signal.
With reference to fig. 2, in a specific implementation, the signal sending end 214 sends the infrared signal including the key value to the infrared controlled device 2D, and when performing corresponding key value operation detection on the infrared controlled device 2D, if the infrared controlled device 2D fails and cannot respond to the infrared signal, on one hand, an alarm signal may be output to remind a tester to check the infrared controlled device in time; on the other hand, a fault feedback signal may be output and recorded by the master control device, and therefore, the signal simulation module may further include a fault alarm unit 22 and a fault feedback unit 23, where:
the fault alarm unit 22, coupled to the controller 212, is adapted to output a fault alarm signal when the infrared controlled device 2D does not respond to the infrared signal transmitted by the signal transmitting end 214.
The fault feedback unit 23, coupled to the controller 212, is adapted to output a fault feedback signal to the controller 212 when the infrared controlled device 2D does not respond to the infrared signal sent by the signal sending end 214.
As a specific example, the malfunction warning unit 22 may include an LED lamp, when the color of the LED changes from green to red when the LED emits light, it indicates that the infrared controlled device malfunctions, and it needs to be checked in time.
In some other embodiments of the present invention, the signal simulation module 20 may further include a protection circuit unit.
In some embodiments of the present invention, referring to a schematic connection relationship diagram of modules of an infrared remote control device in the present invention shown in fig. 3, where fig. 3 shows a connection relationship of a main board 33 in a transit module 31, a connection module 32, and a signal simulation module, where:
the main board 33 may be an infrared learning board, and the infrared learning board may simulate an infrared signal in two ways, where the first infrared simulation way is to collect and store infrared signals of different types of target remote control devices by corresponding infrared communication devices, and then identify and store a required type of the infrared signal; the second method is to completely copy the infrared remote control signal sent by the target remote control device, then store the infrared remote control signal in a storage unit, such as an EEROM, and remove the stored waveform data when sending the infrared remote control signal, so as to restore the original infrared remote control signal.
Since the second infrared signal simulation mode can simulate the key value corresponding to the infrared signal of any one target remote control device, and thus can perform corresponding key operation detection on more infrared controlled devices, in some embodiments of the present invention, the second infrared signal simulation mode is adopted.
With reference to fig. 3, the second interface 331 of the infrared learning board may be a 4-pin interface, the controller 332 may be a single chip microcomputer, the signal receiving terminal may be an infrared signal receiving head 333, the signal sending terminal may be an infrared signal sending head 334, the storage unit may be an EEROM, and the storage unit is embedded in the single chip microcomputer 332 and is adapted to store a key value simulated by the infrared receiving head 333.
In some embodiments of the present invention, the 4 pins of the second interface 331 are a power supply (VDD) pin, a receive data (RXD) pin, a transmit data (TXD) pin, and a Ground (GND) pin, respectively.
As a specific example, as shown in fig. 3, the level of the power supply pin may be 5V.
In a specific implementation, in order to implement the omnidirectional control, the number of the infrared signal transmitting heads 334 may be expanded, for example, the infrared signal transmitting heads 334 of the signal simulation module 33 may be expanded to be connected in parallel by 6.
In a specific example, the working principle of the infrared learning board is as follows: when the TXD terminal is at a high level 1, at this time, the infrared signal receiving head 333 is at a high level 1, and the infrared signal receiving head 333 cannot receive an infrared signal sent by the target remote control device, that is, cannot simulate a key value; once the infrared signal receiving head 333 receives the infrared signal sent by the target remote control device, according to the NEC protocol, a change of a falling edge is generated, the infrared signal receiving head 333 may simulate a key value corresponding to the infrared signal, store the key value into the EEROM, and send the stored key value to the infrared controlled device by the infrared signal sending head 334 when the TXD terminal is at a low level of 0.
In a specific implementation, in order to shorten the time for the infrared learning board to simulate the key value of the target remote control device and the time for detecting the infrared controlled device, the baud rate (bps) of the infrared learning board may be adjusted. For example, 4800bps is adjusted to 9600 bps.
Since the level of the communication interface of the infrared learning board is TTL level and the level of the communication interface of the main control device (not shown in fig. 3) is USB level, the level logics between the two are not consistent, and if the infrared learning board and the main control device are directly connected, the two cannot communicate with each other, and therefore, the level needs to be converted into a communication level that both sides can identify, and in some embodiments of the present invention, the infrared learning board and the PC terminal need to be coupled by a corresponding transfer serial port.
Therefore, in a specific implementation, the first interface of the transit module 31 may include a USB interface 311, and the second end of the transit module is provided with a 4-wire TTL serial port 312, where:
the USB interface 311 may be coupled to the PC terminal;
the pins of the 4-pin TTL serial port 312 are the same as the pins of the 4-pin port of the second interface 331, and are a power pin, a data receiving pin, a data sending pin and a ground pin, wherein the power pin of the 4-pin TTL serial port 312 is coupled to the power pin of the signal simulation module 33; a receive data pin thereof is coupled to a receive data pin of the signal simulation module 33; a data transmission pin of the signal simulation module 33 and a data transmission pin of the signal simulation module; the ground pin of which is coupled to the ground pin of the signal simulation module 33.
In the embodiment of the present invention, the infrared learning board may be coupled to the PC terminal through the USB interface 311 and the 4-wire TTL serial port 312, and a driving signal (a signal having a USB level) from the PC terminal is converted into a TTL signal that can be identified by the infrared learning board, so that the infrared learning board enters an infrared signal simulation mode.
In other embodiments, different devices can control the same infrared controlled device through different connection serial ports and infrared learning boards.
For example, the mobile devices such as a mobile phone and a tablet can control the infrared controlled device through the bluetooth serial port module and the infrared learning board; or, the infrared controlled equipment is remotely controlled through the WiFi serial port module and the infrared learning board.
In some embodiments of the present invention, the 4-wire TTL serial port 312 may specifically be a CH430 serial port, where the CH430 is a serial port supporting a UART protocol, and since the CH430 serial port is coupled to the infrared learning board, the infrared learning board also needs to support the UART protocol to receive a driving signal from the PC, where the driving signal may be HEX data with a length of 5 characters, for example: the drive signal may be A1FD01 xxDF.
As another specific example, when the 4-wire TTL serial port 312 is a CH430 serial port, at this time, the serial port terminal pins may further include a power supply pin with a level of 3.3V, wherein if the CH430 serial port uses a 5V power supply voltage, the VCC pin terminal inputs an external 5V power supply, and the V3 pin is externally connected to a capacitor; if the CH430 serial port uses 3.3V power voltage, its VCC pin is connected to the V3 pin and is externally connected to an external 3.3V power supply.
Because the serial port module is the CH430 serial port, the controller in the learning module can be realized by adopting a universal single chip microcomputer, and other circuit units or terminals and the like can also be realized by adopting universal components, so that the realization cost can be reduced.
With continued reference to fig. 3, in some embodiments of the present invention, the connection module 32 may specifically include a 4-pin flat cable, and both ends of the 4-pin flat cable have 4 pin interfaces, wherein 4 pins of the first end of the 4-pin flat cable are respectively coupled to a power (5V) pin, a TXD pin, an RXD pin and a GND pin of the 4-wire TTL serial port 312, and 4 pins of the second end of the 4-pin flat cable are coupled to the power pin, the receive data pin, the transmit data pin and the ground pin of the signal simulation module 33 in the same manner as 4 pins of the first end of the 4-pin flat cable. For example, when the pin of the first end of the 4-pin flat cable is coupled to the TXD pin, the corresponding pin of the second end needs to be coupled to the TXD pin.
In some other embodiments of the present invention, the switch module and the signal simulation module may be coupled in a cross-bar manner. For example, the TXD pin of the patching module is coupled with the RXD pin of the signal emulation.
Therefore, the main control device can output the driving signal through the USB interface, and the driving signal with the USB level is converted into the driving signal with the TTL level through the 4-wire TTL serial port. Because the 4-wire pins of the 4-wire TTL serial port are respectively coupled with the corresponding pins of the first interface of the signal simulation module in a direct connection mode, the driving signal output by the PC end can be output to the infrared learning board and recognized by the infrared learning board, and the infrared learning board can enter an infrared signal simulation mode.
When the infrared learning board receives an infrared signal from a target remote control device, an infrared signal receiving head in the infrared learning board can simulate a key value corresponding to the infrared signal, and the key value corresponding to the infrared signal is sent to an infrared controlled device to be tested by an infrared signal sending head according to a preset key value sequence, or the key value corresponding to the infrared signal is stored by a storage unit firstly, and then the key value corresponding to the infrared signal is sent to the infrared controlled device to be tested by the infrared signal sending head according to the preset key value sequence until a finishing instruction is received, so that the detection of the infrared controlled device is finished.
In order to make the infrared remote control device of the present invention better understood and implemented by those skilled in the art, a specific application scenario is described as an example.
Referring to fig. 4, a schematic diagram of a testing principle of the infrared remote control device in a specific application scenario in the present invention is shown, wherein the infrared remote control device 40 is adapted to simulate a key value of the target remote control device 4A and send the key value to the infrared controlled device 4B to be tested.
In a specific implementation, the target remote control device 4A may be a television remote controller, and correspondingly, the infrared controlled device 4B may be a television.
As a specific example, in the first step of the test, a main control device (not shown in fig. 4) needs to output a driving signal, and under the action of the driving signal, the infrared remote control device may enter an infrared signal simulation mode, at this time, an internal simulation key may be pressed, and the infrared remote control device may simulate a key value of a television remote controller.
According to actual requirements, an infrared signal corresponding to a key required by testing the television can be sent to the infrared remote control device through the television remote controller. After the infrared signal transmitted by the television remote controller is received by the infrared remote control device, the infrared remote control device can simulate a key value corresponding to the infrared signal, store the key value, and transmit the key value to a television to be tested according to a preset key value sequence until an ending instruction is received, so as to complete the detection of the television.
It should be noted that if there is an un-simulated key value, the television remote controller needs to resend the infrared signal corresponding to the key, and the infrared remote control device may learn the key value again.
In some other embodiments of the present invention, the infrared controlled device 4B may be a set-top box, an air conditioner, a network television, a sweeping robot, a DVD, and other devices having an infrared function, and the target remote control device 4A may be a remote control apparatus corresponding to the electronic device.
Although the embodiments of the present invention are disclosed above, the embodiments of the present invention are not limited thereto.
