The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
The method of upgrading a home appliance through an infrared signal, the system of upgrading a home appliance through an infrared signal, and the home appliance according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method of upgrading a home appliance through an infrared signal according to an embodiment of the present invention. In the embodiment of the invention, the household appliance can be an air conditioner, a television or the like.
As shown in fig. 1, the method for upgrading a home appliance through an infrared signal includes:
s1, acquiring upgrade data.
S2, determining a high level time T1 and a low level time T2 of an infrared signal (shown by referring to FIG. 2) according to the upgrade data to convert the upgrade data into infrared emission data, wherein the emission data comprises a plurality of combinations of the high level time T1 and the low level time T2, and each combination of the high level time T1 and the low level time T2 forms 4Bit data.
S3, transmitting infrared emission data to the household appliance through the infrared emitter so as to upgrade the household appliance.
According to one embodiment of the present invention, if the first two bits of the upgrade data are 00, the high level time T1 is set as the first time; if the first two bits of the upgrade data are 01, setting the high level time T1 as a second time, wherein the second time is longer than the first time; if the first two bits of the upgrade data are 10, setting the high level time T1 as a third time, wherein the third time is greater than the second time; if the first two bits of the upgrade data are 11, the high level time T1 is set to a fourth time, wherein the fourth time is greater than the third time.
According to one embodiment of the present invention, if the last two bits of the upgrade data are 00, the low level time T2 is set as the first time; if the last two bits of the upgrade data are 01, setting the low level time T2 as a second time, wherein the second time is longer than the first time; if the last two bits of the upgrade data are 10, setting the low level time T2 as a third time, wherein the third time is greater than the second time; if the last two bits of the upgrade data are 11, the low level time T2 is set to a fourth time, wherein the fourth time is greater than the third time.
The first time, the second time, the third time and the fourth time can be set according to practical needs, for example, the range of the first time can be [500us,600 us), the range of the second time can be [600us,700 us), the range of the third time can be [700us,800 us), the range of the fourth time can be [800us,900 us), and preferably, the first time is 550us, the second time is 650us, the third time is 750us and the fourth time is 850us.
It should be noted that, the scheme of the invention is to upgrade the software of the household appliance through infrared signals. On the premise that the infrared receiving heads are required to be installed on the household appliances in advance, all household appliances are provided with the infrared receiving heads. Therefore, the invention can realize the software upgrade by considering the software.
Specifically, the present invention needs to improve the existing remote control communication protocol and increase the communication speed. The minimum time for the high and low levels of the common infrared signal before modification is 500us, wherein the high level of 500us and the low level of 500us represent 0;500us high and 1500us low represent 1, and the calculated average rate is (500 us+500us+500us+1500 us)/2=1500 us, i.e., 1500us emits one data.
The scheme of the invention is as follows: the low level times T2 are set to 550us,650us,750us,850us, respectively, and represent 00, 01, 10, 11, respectively, and two Bit byte data can be transferred. The high level time T2 is set to 550us,650us,750us,850us, respectively, and is expressed as 00, 01, 10, 11, and can be processed into two Bit byte data as well, which corresponds to processing of 4Bit data, and the calculated average rate is (550 us+650us+750us+850 us)/4=700 us, that is, 700us sends out two data, and one data needs 350us. By calculation, the average rate of the present invention is increased by approximately 5 times over conventional infrared signal protocols.
Taking 32K software as an example to calculate the upgrading time of the invention, the required upgrading time is 32 x 1024 x 8 x 350us, namely, the upgrading is completed in about 90 seconds, which is obvious compared with the original proposal. Even if the scheme of converting infrared into UART is used, the lifting rate is obvious, and the lifting rate is about 180 seconds.
In practical application, when the household appliance needs to be upgraded, a user can send an upgrade instruction through an upgrade key on a remote controller of the household appliance. After receiving the upgrade instruction, the main control board acquires upgrade data, determines high level time T1 and low level time T2 of the infrared signal according to the upgrade data, converts the upgrade data into infrared emission data, and sends the infrared emission data to the household appliance through the infrared emitter. The household appliance receives and stores infrared emission data according to the infrared communication protocol, and judges whether all the data are received. If yes, the receiving is successful; if not, whether the receiving time (such as 10 min) is over, if so, the receiving is failed, otherwise, the infrared transmitting data is continuously received and stored according to the infrared communication protocol address until the receiving time is over.
Further, according to an embodiment of the present invention, before determining the high level time T1 and the low level time T2 of the infrared signal according to the upgrade data to convert the upgrade data into the infrared emission data, further comprising: the upgrade data is segmented according to the address to divide the upgrade data into a plurality of upgrade data blocks.
Specifically, the infrared emission data sent by the infrared communication protocol of the present invention are separately processed according to the address module, for example, as shown in fig. 3, the remote control emission data module is divided into a remote control emission data module 1, a remote control emission data module 2, remote control emission data modules 3 and … …, and a remote control emission data module N; the data modules of the main control receiving module are divided into a remote control transmitting data module 1, a remote control transmitting data module 2, remote control transmitting data modules 3 and … … and a remote control transmitting data module N which are in one-to-one correspondence with the remote control transmitting data modules, so that part of signal interference does not receive infrared signals, the address can be continuously updated after being received, and the whole re-receiving processing is not needed.
Specifically, when the remote control starts to transmit data, each module of the remote control transmitting data sequentially and circularly transmits the remote control transmitting data to the corresponding main control receiving data module, when the main control receiving data module receives the data of the corresponding remote control transmitting data module successfully, the next module data is waited to be received until all module programs are received, the receiving is successful, then the program upgrading is stopped, and the upgrading is successful. Or if all the module upgrade data are not received within the receiving time (such as 10 min), the program upgrade is exited and the upgrade fails.
For example, 1 module is considered to be 1K capacity. All capacities 32K are sent with a remote control loop. If the intermediate 13K module fails to accept, the next time the 13K module is sent is waited for to update. Thus, even if some of the middle part fails, the second or third time is successful when the full reception is successful. This eliminates the need to re-accept each time an acceptance fails.
It should be noted that, this scheme transmits data through infrared remote control, under the condition that home appliance was circular telegram, can directly upgrade with infrared remote controller to an infrared remote controller can carry out the software upgrade to a single, also can carry out the software upgrade to a plurality of equipment simultaneously, convenient after-sale maintenance. The infrared communication protocol in the scheme also quickens the software upgrading time. The time and cost combination considerations of the present invention are optimal compared to network upgrades and conventional UART upgrades.
In summary, according to the method for upgrading a home appliance through an infrared signal in the embodiment of the present invention, upgrade data is acquired first, then high level time T1 and low level time T2 of the infrared signal are determined according to the upgrade data to convert the upgrade data into infrared emission data, wherein the emission data includes a plurality of combinations of the high level time T1 and the low level time T2, each combination of the high level time T1 and the low level time T2 forms a 4Bit data, and finally the infrared emission data is transmitted to the home appliance through an infrared emitter to upgrade the home appliance. Thus, the method can upgrade the software of the household appliance through the infrared transmitter, so that the upgrade cost is reduced as a whole.
