Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
According to the embodiment of the invention, the infrared code learning instruction sent by the gateway equipment is received, the infrared code sending equipment is activated to carry out infrared code learning and obtain the infrared signal, then the infrared code signal corresponding to the learning instruction is extracted from the infrared signal and stored, and further the corresponding serial number is set for the infrared code signal, so that the infrared code is convenient to call after learning, and the problems that the existing infrared code learning technology depends on manual learning, the learning efficiency is low, special infrared code learning equipment is needed for assistance, the learning difficulty is high, and the equipment is inconvenient to update are solved.
In the embodiment of the invention, the execution subject of the process is the infrared coded transmitting equipment. The transmitting equipment of the infrared codes is equipment with an infrared transmitting module, and other equipment is controlled through infrared signals. The infrared encoded transmitting device may be a stand-alone device including, but not limited to: an infrared transponder, an infrared remote control device; the infrared coded transmitting device can also be integrated into other devices to work as a functional module, such as a mobile terminal comprising an infrared transmitting module. Fig. 1 shows a flowchart of an implementation of a learning method for infrared codes according to an embodiment of the present invention, which is detailed as follows:
in S101, an infrared code learning instruction transmitted by the gateway device is received.
In this embodiment, after acquiring new infrared code information, the gateway device generates an infrared code learning instruction, where the infrared code learning instruction is used to inform the transmitting device of the infrared code that infrared code learning needs to be performed. It should be noted that the infrared code transmitting device may obtain the infrared code learning instruction through a radio frequency communication module, such as a WiFi communication module, a bluetooth communication module, a low power consumption bluetooth communication module, and other radio frequency network communication modules; the infrared code learning instruction can also be acquired by an infrared signal receiving module.
Optionally, in this embodiment, after the transmitting device of the infrared code is turned on, and/or during the working process, a code query instruction is sent to the gateway device at a preset time interval, and the gateway device determines whether the infrared code in the transmitting device of the infrared code needs to be updated according to the code query instruction. And if the gateway equipment determines that the infrared code transmitting equipment needs to perform infrared code learning, sending an infrared code learning instruction to the infrared code transmitting equipment, and executing the relevant operation of S101. Since the transmitting device of the infrared code may be in a closed state when the gateway device initiates the learning operation of the infrared code, and the learning opportunity of the infrared code will be missed, in order to solve the problem, the transmitting device of the infrared code may actively send a code query instruction to the gateway device, so that the gateway device determines whether the infrared code updating needs to be performed on the transmitting device of the infrared code according to the query instruction.
Optionally, in this embodiment, the infrared code learning instruction includes a device identifier. The gateway device can broadcast the infrared code learning instruction through the radio frequency communication network or the infrared communication network, the infrared code transmitting device extracts the device identification contained in the instruction after receiving the infrared code learning instruction, matches the device identification with the local device identification, and if the matching is successful, the related operation of S102 is executed; otherwise, if the matching is unsuccessful, continuing to wait for receiving the infrared code learning instruction sent by the gateway equipment. Because a plurality of infrared code transmitting devices can belong to the same gateway device, the infrared code learning instruction sent by the same gateway device is received. Therefore, in order to determine whether the device corresponding to the infrared code learning instruction is the self device by each infrared code transmitting device, the device identification contained in the infrared code learning instruction needs to be matched.
Optionally, in this embodiment, the gateway device is to be connected to a server. The user can upload the new control strategy to the server, and the server sends the control strategy to the corresponding gateway equipment after receiving the control strategy, so that the gateway equipment can learn the infrared coding emission equipment associated with the control strategy. After receiving the control policy sent by the server, the gateway device will perform the relevant operation of S101.
In S102, acquiring an infrared signal, and extracting an infrared coding signal sent by the gateway device from the infrared signal; the infrared coding signal is generated by the gateway device according to a control strategy sent by the server and a preset infrared coding conversion algorithm.
In this embodiment, after receiving the infrared code learning instruction sent by the gateway device, the infrared code transmitting device monitors and acquires the infrared signals in the environment, extracts and stores the infrared code signals sent by the gateway device from the acquired infrared signals.
In this embodiment, after receiving a control policy sent by a server, a gateway device converts the control policy into an infrared encoded signal according to a preset infrared code conversion algorithm; wherein, different infrared code signals determine the corresponding control strategy by identifying the jump times of high and low levels of the infrared signals and the duration of each level.
Specifically, the control policy sent by the server may include a signal format of the infrared encoded signal, and the gateway device generates the corresponding infrared encoded signal according to the signal format corresponding to the control policy. If the control strategy sent by the server is as follows: and after the high level of the infrared signal lasts for 3s, jumping to the low level and lasting for 2s, then jumping to the high level and lasting for 1.3s, and ending. The gateway device can directly generate the corresponding infrared coding signal according to the control strategy.
Specifically, the control policy sent by the server may be operation instruction information, and the gateway device queries a corresponding infrared encoding mode according to the operation instruction information, and generates a corresponding infrared encoding instruction according to the operation instruction information included in the control policy and the sequence of each operation instruction information. If the server issues a combined control strategy: starting up, adjusting the volume to 50 percent and adjusting the brightness to 50 percent. After receiving the control strategy, the gateway device queries a corresponding relation table of the operation instructions and the infrared codes, determines that three operation instructions of starting up, adjusting the volume to 50% and adjusting the brightness to 50% correspond to obtain the infrared codes, and generates infrared code signals of the control strategy according to the three infrared codes and the corresponding sequence.
Optionally, in this embodiment, the server may adjust an infrared code corresponding to an existing control policy. Because some infrared coded signals are easily influenced by environmental factors in the using process, the controlled equipment is identified as another operation instruction after receiving the infrared coded signals and executes wrong operation, and therefore, in order to optimize the infrared coded signals, the infrared codes of the existing control strategy can be adjusted. Specifically, the adjusting process may be: and the server sends the control strategy number to be adjusted and the corresponding infrared coding rule to the controlled equipment and the gateway equipment. After receiving the information, the gateway device executes the relevant operations of S101 and S102, so that the transmitting device of the infrared code adjusts the infrared code signal corresponding to the infrared strategy; on the other hand, the controlled device updates the control strategy after receiving the information, so that after receiving the adjusted infrared coding signal, the controlled device executes the operation corresponding to the control strategy.
In S103, a number corresponding to the infrared encoding signal is set.
In this embodiment, after acquiring a complete ir encoded signal, the transmitting device of the ir code will identify the encoding rule of the ir encoded signal. For example, signal characteristic parameters and coding rules related to the ir-encoded signal, such as the number of transitions, the timing of the transitions, the values of the high and low levels, the duration of the levels, and the overall time of the signal of the ir-encoded signal, are stored, so as to reproduce the ir-encoded signal according to the above information.
In this embodiment, the ir-coded transmitting device will assign a number to each ir-coded signal to identify the ir-coded signal. When a user needs to send the infrared coding signal, the corresponding serial number is directly sent to the transmitting equipment of the infrared code, and then the corresponding infrared coding signal is sent.
As can be seen from the above, in the infrared code learning method provided in the embodiment of the present invention, the infrared code learning instruction sent by the gateway device is received, the infrared code sending device is activated to perform infrared code learning, then the infrared code signal corresponding to the learning instruction is extracted from the obtained infrared signal, and after the infrared code signal is extracted, the infrared code signal is stored and the corresponding number is set for the infrared code signal, so that the infrared code is called after learning. Therefore, the infrared code transmitting device does not need to be adjusted on site by a special infrared code learning device, and the infrared code transmitting device can automatically learn the infrared codes according to the learning instruction and the infrared code signals, so that the infrared code learning efficiency is improved, the learning difficulty of the infrared code transmitting device is reduced, and the equipment manufacturer can conveniently update the control strategy.
Referring to fig. 2, fig. 2 is a flowchart illustrating an implementation of an infrared code learning method S102 according to another embodiment of the present invention. Compared with the previous embodiment, the infrared code learning method S102 provided in this embodiment specifically includes S201 to S204.
In S201, it is monitored whether the infrared signal satisfies a preset signal start determination condition.
In this embodiment, after receiving an infrared code learning instruction sent by a gateway device, an infrared code transmitting device continuously monitors an infrared signal in an environment, matches the acquired infrared signal with a preset code start triggering condition, and determines whether to start recording the infrared signal.
In this embodiment, if the transmitting device of the infrared code determines that a certain infrared code signal meets a preset code start triggering condition, the transmitting device locks the infrared signal and performs the relevant operation of S202; otherwise, the infrared signal is continuously monitored and matched with the code starting triggering condition. Optionally, if none of the received infrared information satisfies the preset code start triggering condition within a preset time, the related operation of S201 is stopped. If the receiving time exceeds the waiting receiving time, the infrared coding signal returned by the gateway equipment is not received, the monitoring is stopped, and the normal working mode is returned.
Optionally, in this implementation, the start-of-encoding trigger condition is to determine whether the infrared signal is an infrared pulse signal with a preset frequency. Before sending the infrared code signal, the gateway device adds a high-frequency pulse signal in front of the infrared code signal as a start mark of the infrared code signal. The infrared coded transmitting device continuously monitors whether the received infrared signal has the infrared pulse signal with the preset frequency through the infrared signal receiving module. If a certain infrared signal contains the infrared pulse signal with the preset frequency, the infrared signal meets the preset code starting triggering condition.
Optionally, in this embodiment, the encoding start triggering condition is to determine whether the level of the infrared signal is greater than a preset level threshold. The gateway device may send an ir signal with a higher level as a start flag before sending the ir encoded signal. Since the general signal strength of the environmental noise is small, that is, the level value of the signal is relatively small, the gateway device may indicate that the transmitting device of the infrared code needs to start recording the infrared signal as the infrared code signal by transmitting a high-level infrared signal having a large difference from the environmental noise.
In S202, if the infrared signal satisfies a preset signal start determination condition, recording of the infrared signal is started.
In this embodiment, when the sending device of the infrared code determines that the infrared signal meets the preset code start triggering condition, the infrared signal is stored. Specifically, the infrared-coded transmitting device may record the infrared signal by means of a waveform map, a sequence of sampled data, or the like.
In S203, if it is detected that the infrared signal satisfies a preset signal end determination condition, recording of the infrared signal is stopped.
In this embodiment, when the infrared-coded transmitting device detects that the infrared signal satisfies the preset signal-end determination condition, it will stop recording the infrared signal, and perform the correlation operation of S204 on the infrared signal obtained in the time interval: and the time from the moment when the infrared signal meets the code starting triggering condition to the moment when the infrared signal meets the signal ending judging condition.
Optionally, in this embodiment, the preset signal ending determining condition may also be the same as the preset coding start triggering condition, and specifically, the preset signal ending determining condition may be: and judging whether the infrared signal is an infrared pulse signal with a preset frequency or not, or judging whether the level of the infrared signal is greater than a preset level threshold value or not. When the transmitting equipment of the infrared code monitors that the infrared signal meets the preset code starting triggering condition again, the infrared code signal is determined to be finished.
Optionally, in this embodiment, the preset encoding end condition may be: and judging whether the infrared signal reaches a preset signal length. Since the corresponding signal length of each ir-encoded signal may be the same, when the ir-encoded transmitting device records that the obtained ir signal has reached the preset signal length, it indicates that the ir signal has been recorded and belongs to a complete ir-encoded signal, and ends the recording, and performs the relevant operation of S203. It should be noted that the transmitting device of the infrared code may determine the signal length of the infrared code according to the time length of acquiring the infrared signal.
In S204, the recorded infrared signal is taken as the infrared encoding signal.
In this embodiment, the infrared encoded transmitting device takes the infrared signal acquired in S202 as the infrared encoded signal and stores it. Optionally, the transmitting device of the infrared code may also extract a signal characteristic parameter of the infrared signal, use the signal characteristic parameter as the signal characteristic parameter of the infrared code, and then generate a corresponding infrared code signal through the signal characteristic parameter.
In the embodiment of the invention, the infrared coded transmitting equipment extracts the corresponding interval signal in the infrared signal as the infrared coded signal by detecting whether the infrared signal meets the coding start triggering condition and the signal end judging condition, so that the identification efficiency and the identification accuracy of the infrared coded signal are improved.
Referring to fig. 3, fig. 3 is a flowchart illustrating an implementation of the infrared code learning method S201 to S203 according to another embodiment of the present invention. With respect to the embodiment shown in fig. 2, the method S201 to S203 for learning the infrared code provided in this embodiment includes the following steps:
further, as another embodiment of the present invention, the S201 includes S301 and S302:
in S301, if it is monitored that the level value of the infrared signal has jumped, the holding time of the level value is determined.
In this embodiment, the ir encoded transmitting device will monitor whether the level of the received ir signal is changed, for example, from low to high or from high to low. If the transmitting device of the infrared code detects that the level value of the infrared signal jumps, the step S301 is executed.
In this embodiment, the ir-coded transmitting device recognizes whether the ir signal has a transition by capturing the falling and/or rising edge of the ir signal. Optionally, the ir encoded transmitting device will determine whether the ir signal has jumped or not based on the falling time of the falling edge and the difference between the falling levels and/or the rising time of the rising edge and the difference between the rising levels of the level values of the ir signal. The standard level jump is equivalent to a pulse signal, and in an ideal environment, the duration of the level jump should be 0, but due to the influence of environmental noise in the environment, the level jump has a certain fall time and rise time, so that whether the level change belongs to the level jump can be determined according to the comparison between the fall time and the rise time of the level jump and a preset time threshold.
In this embodiment, the ir encoded transmitting device will obtain the duration of the level value after determining that the ir signal has hopped. Specifically, the IR coded transmitting device may detect whether the second transition of the IR signal occurs and use the time interval between the first and second transitions as the duration of the level value.
Optionally, in this embodiment, if the second jump of the infrared signal is detected within a preset maximum level holding time, that is, the holding time of the level value is greater than the preset maximum level holding time, the maximum level holding time is taken as the holding time of the level value, and the recording of the duration time of the infrared signal is stopped.
In S302, it is determined whether the infrared signal includes a signal start identifier according to the retention time of the level value and a preset encoding format recognition algorithm.
In the present embodiment, since the partial infrared coded signal will use a low level or a high level lasting for a fixed time as the signal start indicator, for example, a National Electrical Code (NEC Code) uses a high level lasting for 9ms as the start indicator. Therefore, the infrared coded transmitting device can match with a preset coding format recognition algorithm according to the duration time of the level value, determine whether the level value is the signal starting identifier in the preset coding rule, and then determine whether the infrared signal contains the signal starting identifier.
In this embodiment, the preset encoding format recognition algorithm may include a plurality of encoding format rules, and the infrared encoding transmitting device matches the holding time of the level value with each encoding format rule, and then determines whether there is a matching encoding format rule in the holding time of the level value. If the infrared signal does not conform to any infrared coding rule, the infrared signal does not contain the infrared coding signal.
In this embodiment, the S202 specifically includes:
in S303, if the infrared signal includes a signal start identifier, recording of the infrared signal is started.
In this embodiment, when the transmitting device of the infrared code determines that the infrared signal includes the signal start identifier, it indicates that the infrared signal satisfies the preset signal start determination condition, and then starts to record the infrared signal.
In the embodiment of the invention, when monitoring the infrared signal level to jump, the infrared coded transmitting equipment determines the duration of the level after jumping, then determines whether the duration of the level is matched with the signal start identifier of the infrared code, and then determines to start recording the infrared signal, so that the recording start time of the infrared coded signal is identified, and the accuracy of acquiring the infrared coded signal is improved.
Further, as another embodiment of the present invention, the S203 specifically includes:
in S304, if the level value of the infrared signal does not jump within a preset time, the recording of the infrared signal is stopped.
In this embodiment, when the infrared encoding transmitting device detects that the level value of the infrared signal does not change within the preset time during the recording process, it is determined that the infrared encoding signal has been transmitted. Since the infrared signal with the level jump belongs to the unnatural waveform signal, when the infrared signal does not jump any more within the preset time, it indicates that the infrared signal in the environment is no longer the infrared coded signal sent by the gateway device.
In the embodiment of the invention, the infrared coded transmitting equipment takes the fact that whether the level of the infrared signal is overtime or not and does not jump as a signal ending judgment condition. When the transmitting equipment of the infrared code judges that the infrared signal jumps within the preset time, the recording is continued, and the timing is performed again; when the transmitting equipment of the infrared code determines that the infrared signal does not jump after the preset time is exceeded, the recording is finished, so that the recording finishing time of the infrared code signal is identified, and the accuracy of acquiring the infrared code signal is improved.
Referring to fig. 4, fig. 4 is a flowchart illustrating an implementation of a method for learning infrared codes according to another embodiment of the present invention. The infrared code learning method provided in this embodiment includes the following steps, which are detailed as follows:
since the specific implementation processes of S401 to S403 are completely the same as those of S101 to S103, the detailed description is please refer to the related descriptions of S101 to S103, and will not be described herein again.
Further, as another embodiment of the present invention, after the step S103, the method further includes:
in S404, an ir code transmission instruction is received, where the ir code transmission instruction includes the number.
In this embodiment, the infrared code transmitting device may obtain the infrared code transmitting instruction sent by the gateway device or other terminals through the radio frequency network receiving module, and may also obtain the infrared code transmitting instruction sent by other terminals through the infrared signal receiving module.
In this embodiment, the infrared code sending instruction will include the number of the infrared code signal to be sent, and the gateway device or other control terminal determines the control policy indicated by each number by obtaining the correspondence table between the control policy and the number, and then encapsulates the number in the infrared code sending instruction.
In S405, according to the number included in the infrared code transmission instruction, an infrared code signal corresponding to the number is generated and transmitted.
In this embodiment, after receiving the infrared code sending instruction, the infrared code sending device extracts the number included in the infrared code sending instruction, and queries the infrared code signal corresponding to the number according to a preset correspondence list between the number and the infrared code signal.
Optionally, in this embodiment, if the transmitting device of the infrared code does not inquire the infrared code signal corresponding to the number, a wrong number instruction is returned to notify the transmitting end of the infrared code transmitting instruction to re-determine the correct number.
In this embodiment, after the transmitting device of the infrared code inquires the infrared code signal corresponding to the serial number, the transmitting device of the infrared code reproduces the infrared code signal according to the stored infrared code signal and sends the infrared code signal to the controlled device corresponding to the transmitting device of the infrared code, so that the controlled device executes the operation of the control strategy corresponding to the controlled device according to the infrared code.
Optionally, in this embodiment, the transmitting device of the infrared code will generate a corresponding infrared code signal according to the characteristic parameter of the infrared code signal. The characteristic parameters of the infrared code are the duration and the jump time of each high and low level in the infrared code signal. The infrared encoding transmitting device will generate a corresponding infrared encoding signal through a Pulse Width Modulation (PWM) module.
Specifically, in the present embodiment, the infrared-coded transmitting device determines the duration of each high-low level by a timer. When the value of the timer reaches the duration time corresponding to the high level, simulating the high level to jump to the low level by closing the PWM module, and resetting the timer; and when the value of the timer reaches the duration time corresponding to the low level, the PWM module is started to simulate the low level to jump to the high level, and the timer is reset. By repeating the above two steps, the corresponding infrared code signal is produced.
In the embodiment of the invention, the corresponding infrared coding signal is generated by sending the infrared coding sending instruction to the infrared coding sending device, so that the aim of controlling other controlled devices is fulfilled.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
