Detailed Description
The invention aims to provide an air conditioner parameter reading method and an air conditioner, which can effectively solve the problem of abnormal data reading caused by short-circuit of an SDA data line to the ground.
In order to make the objects, technical solutions and effects of the present invention clearer and more specific, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1 and fig. 2 together, in the method for reading parameters of an air conditioner provided by the present invention, the air conditioner includes a controller 11 and a memory 12, wherein data communication is performed between the controller 11 and the memory 12 through an I2C bus 13. The communication principle is to generate signals required by the I2C bus 13 protocol for data transfer by controlling high-low level time sequences of the SCL clock line and the SDA data line in the I2C bus 13. In the idle state of the I2C bus 13, both lines are typically pulled high by the pull-up resistor connected above, holding a high level. I2C communication is divided into hardware I2C and software simulation I2C, wherein the hardware I2C corresponds to I2C peripheral equipment on a chip and is provided with a corresponding I2C driving circuit, and an I2C pin used by the I2C driving circuit is special; software I2C typically uses GPIO pins and uses software to control pin states to simulate I2C communication waveforms. The efficiency of the hardware I2C is far higher than that of the software, and the interface of the software I2C is flexible because the software I2C is not limited by pins. Analog I2C is the way software emulates registers through GPIO pins, while hardware (firmware) I2C directly invokes internal registers for configuration. Hardware I2C speeds are faster than analog and can be accessed with DMA (direct memory access), direct memory 12. The software I2C uses the program control SCL clock line and SDA data line to output high and low levels, simulating the timing of the I2C protocol.
With continued reference to fig. 2, in this embodiment, the controller 11 includes an SDA port, and the SDA port is connected to the memory 12 through an SDA data line, and the method for reading parameters of the air conditioner includes the following steps:
100. configuring an SDA port as a first GPIO port, and detecting a level signal of the first GPIO port;
200. judging whether the SDA data line is short-circuited or not according to the level signal of the first GPIO port;
300. when the SDA data line is not shorted, the GPIO port is reconfigured as the SDA port to read the air conditioner parameters stored in the memory 12.
In this embodiment, the SDA port in the controller 11 is first configured as a GPIO port before the air conditioner parameters are formally read. The SDA port herein refers to a pin in the controller 11, and the pin is configured by the controller 11 to perform a data transmission function corresponding to the SDA data line, respectively. Also, the controller 11 may configure the pin as a port that can perform other functions, for example, the controller 11 may configure the pin as a general GPIO port. In this embodiment, the controller 11 changes the SDA port to the first GPIO port between the SDA port and reading the air conditioner parameters in the memory 12, then detects the level signal of the first GPIO port, determines whether the SDA data line is shorted to the ground according to the level signal of the first GPIO port, and when determining that the SDA data line is not shorted, then configures the first GPIO port to the SDA port to read the air conditioner parameters stored in the memory 12, thereby effectively avoiding data anomaly caused by the SDA data line short-circuit anomaly.
Further, the step of determining whether the SDA data line is shorted according to the level signal of the first GPIO port includes: when the level signal of the first GPIO port is the first level signal, judging that the SDA data line is short-circuited; and when the level signal of the first GPIO port is the second level signal, judging that the SDA data line is not short-circuited. In this embodiment, the first level signal is a low level signal, and the second level signal is a high level signal. That is, after the SDA port is configured as the first GPIO port by the controller 11, since the first GPIO port is also connected to the SDA data line, if the SDA data line is shorted to ground, the corresponding first GPIO port is shorted to ground, and the level signal of the first GPIO port is a low level signal at this time. If the controller 11 detects that the first GPIO port is a low level signal at this time, then it is determined that the SDA data line is shorted to ground. If the controller 11 detects that the first GPIO port is a high level signal at this time, then it is determined that the SDA data line is not shorted, so as to effectively detect whether the SDA data line is shorted.
Further, the step of judging whether the SDA port is shorted according to the level signal of the first GPIO port further includes: and when the SDA data line is short-circuited, outputting short-circuit abnormal information. That is, when the controller 11 detects that the level signal of the first GPIO port is a low level signal, it determines that the SDA data line is shorted, and outputs the short-circuit abnormal information, so as to facilitate the subsequent targeted fault removal and ensure that the air conditioner parameter reading is normal.
When the controller 11 and the memory 12 communicate through the I2C, the controller 11 acts as a master device, the memory 12 acts as a slave device, and the master device reset may cause a problem that the I2C bus 13 is locked, which is represented by the SCL port being a high level signal and the SDA port being a low level signal all the time. Specifically, during the process of the master device performing the read/write operation, the master device controls the SCL clock line to transmit 8 clock pulses after the start signal, and then pulls down the level signal of the SCL clock line to be low, and at this time, the slave device outputs a response signal to pull down the level signal of the SDA data line to be low. If the master is abnormally reset at this time, the SCL clock line is released to a high level. At this time, if the slave device is not reset, the I2C response is continued, and the level signal of the SDA data line is pulled low until the level signal of the SCL clock line becomes low, and the response signal is terminated. In contrast, for the I2C master device, the level signal of the SCL clock line and the level signal of the SDA data line are detected after reset, and if the level signal of the SDA data line is found to be low, the I2C bus 13 is considered to be occupied, and the level signal of the SCL clock line and the level signal of the SDA data line wait for all the time to become high. Thus, the I2C master waits for the slave to release the SDA signal to pull the level signal of the SDA data line low while the I2C slave waits for the master to pull the level signal of the SCL clock line low to release the reply signal, and the two wait for each other, and the I2C bus 13 enters a locked state.
Referring to fig. 3, further, the controller 11 further includes an SCL port connected to the memory 12 through an SCL clock line. The step of reconfiguring the first GPIO port to an SDA port may further be preceded by:
10. configuring the SCL port as a second GPIO port;
20. setting the level signals of the first GPIO port and the second GPIO port as second level signals;
30. detecting whether the level signals of the first GPIO port and the second GPIO port are set second level signals or not;
40. and when the level signals of the first GPIO port and the second GPIO port are both second level signals, the second GPIO port is reconfigured to be an SCL port.
That is, in order to avoid the problem of the I2C bus 13 being locked after confirming that the SDA data line is not shorted, the level signals of the I2C bus 13 are pulled up to be high, and then whether the level signals of the I2C bus 13 are all high is read, and after confirming that the level signals of the I2C bus 13 are all high, the data is read, so that the situation of the I2C bus 13 being locked can be effectively avoided. Specifically, while configuring the SDA port with a normal GPIO port, the controller 11 may also configure the SCL port as a normal port, in this embodiment, the controller 11 configures the SCL port as a second GPIO port, and then after confirming that the SDA data line is not shorted, sets the level signals of the first GPIO port and the second GPIO port to be the second level signals; and detecting whether the level signals of the first GPIO port and the second GPIO port are set second level signals, if the level signals of the first GPIO port and the second GPIO port are the second level signals, respectively configuring the first GPIO port and the second GPIO port as an SDA port and an SCL port so as to facilitate subsequent I2C communication with the memory 12, thereby avoiding the problem of locking of the I2C bus 13. Otherwise, when any one of the level signals of the first GPIO port and the second GPIO port is the first level signal, the communication fault information is output so as to facilitate the subsequent fault elimination.
Further, referring to fig. 4, the step of reading the air conditioner parameters stored in the memory 12 includes: and checking the parameters of the air conditioner. The controller 11 checks the air conditioner parameters after reading the air conditioner parameters of the memory 12 to improve accuracy of data acquisition.
Specifically, the air conditioner parameters include effective parameters and verification parameters, wherein the step of verifying the air conditioner parameters specifically includes:
50. calculating a check value of the effective parameters according to a preset check rule;
60. and comparing the check value with the check parameter, and when the check value is equal to the check parameter, indicating that the air conditioner parameter is successfully read.
After the controller 11 reads the air conditioner parameters in the memory 12, calculates a check value for the effective parameters in the air conditioner parameters according to a preset check rule, for example, accumulates the effective parameters to obtain the check value, and then compares the check value with the check parameter, if the check value is equal to the check parameter, it indicates that the acquired air conditioner parameters are the required accurate data, so that the accuracy of parameter acquisition is improved by checking the acquired air conditioner parameters.
Further, the invention also provides an air conditioner, which comprises a controller, a memory and an I2C bus, wherein the controller comprises an SDA port and an SCL port, the I2C bus comprises an SDA data line and an SCL clock line, the SDA port is connected with the memory through the SDA data line, and the SCL port is connected with the memory through the SCL clock line; the controller is used for executing the air conditioner parameter reading method; the memory is used for storing parameters of the air conditioner, and the memory in this embodiment is an electrified erasable programmable read-only memory, and since the method for reading parameters of the air conditioner is described in detail above, the details are not repeated here.
In summary, the invention provides a method for reading parameters of an air conditioner and the air conditioner, wherein the air conditioner comprises a controller and a memory, the controller comprises an SDA port, and the SDA port is connected with the memory through an SDA data line; the method for reading the parameters of the air conditioner comprises the steps of configuring an SDA port as a first GPIO port and detecting a level signal of the first GPIO port; judging whether the SDA data line is short-circuited or not according to the level signal of the first GPIO port; and when the SDA data line is not short-circuited, the GPIO port is reconfigured to be the SDA port so as to read the air conditioner parameters stored in the memory. According to the method and the device, whether the SDA data line is short-circuited to the ground is detected before the parameter of the air conditioner is read, so that the data parameter reading abnormality caused by the short-circuited SDA data line to the ground can be effectively avoided.
