Embodiments of the present application will be further described below with reference to the accompanying drawings.

As shown in fig. 1, fig. 1 is an optional flowchart of an update method of an intelligent home system according to an embodiment of the present application, where the intelligent home system includes a central control screen and a micro control unit, the central control screen is provided with a screen main board and a backlight module, the backlight module is electrically connected with a switch unit, the screen main board and the micro control unit are respectively electrically connected with the switch unit, the update method of the intelligent home system may be executed by the micro control unit, and the update method of the intelligent home system includes, but is not limited to, steps S110 to S130 below:

Step S110, receiving a notification signal from the screen motherboard.

The central control screen can be regarded as a mobile terminal which performs man-machine interaction with a customer, is usually deployed at an entrance of a living room or an entrance of a room, is convenient for the customer to operate, and can be LCM, so that a screen of the central control screen can be a liquid crystal display, and a screen main board of the central control screen can be provided with an android or iOS and other operating systems.

The notification signal includes an update advance signal and a keep-alive signal, where the update advance signal may be used to indicate that the central control screen is in an update ready state, i.e., the central control screen is ready to be updated.

The screen main board of the central control screen may analyze the update data packet and predict a time required for analysis, for example, the time required for analysis is 10 seconds, the screen main board may send an update advance notice signal to the micro control unit within 10 seconds of analyzing the update data packet, and may wait for a preset preparation time period when the update data packet is not needed to be analyzed, which is equivalent to that when the central control screen enters the update ready state, the screen main board may wait for a preparation time period to update the central control screen, and send the update advance notice signal to the micro control unit within the preparation time period, so that the micro control unit may disconnect a communication loop between the screen main board and the backlight module in advance.

The keep-alive signal can be used for indicating that the central control screen is in a normal running state, which is equivalent to that the central control screen does not need to be updated, the screen main board of the central control screen can send the keep-alive signal to the micro control unit at regular time, or the screen main board can also send a small number of keep-alive signals to the micro control unit, the micro control unit determines that the central control screen is in the normal running state after receiving the keep-alive signal, and the subsequent micro control unit can determine that the central control screen is kept in the normal running state when not receiving other signals from the screen main board.

Specifically, among notification signals transmitted from the screen main board to the micro control unit, the notification signal may be provided with a status flag bit that may be used to distinguish the notification signal as an update advance notice signal or a keep-alive signal, for example, when the status flag bit is 0, the notification signal is an update advance notice signal, and when the status flag bit is 1, the notification signal is a keep-alive signal.

In one possible implementation manner, the central control screen can update firmware or software in an OTA manner, that is, receive an update data packet in an OTA manner, and also receive the update data packet in a serial port communication manner.

The update of the central control screen may specifically be upgrading the firmware or software version of the central control screen or degrading the firmware or software version of the central control screen, so the update advance notice signal may include an upgrade advance notice signal and a degradation advance notice signal.

Specifically, communication connection can be established between the screen main board of the central control screen and the micro control unit through communication modes such as UART, I2C or GPIO, and based on the established communication connection, the screen main board can send a notification signal to the micro control unit.

Step S120, when the notification signal is an update advance notice signal, a first control signal is generated in response to the update advance notice signal, and the first control signal is sent to the switch unit to control the switch unit to disconnect the communication loop between the screen motherboard and the backlight module, so that the backlight module is in an off state.

The backlight module is used for providing illumination for a display of the central control screen.

After the central control screen enters the update ready state, the screen main board can send an update advance notice signal to the micro control unit, the micro control unit can generate a first control signal after receiving the update advance notice signal and send the first control signal to the switch unit, and the switch unit can disconnect a communication loop between the screen main board and the backlight module after receiving the first control signal.

Specifically, the enabling end of the backlight module may be connected to the first end of the switch unit, the first control end of the screen motherboard may also be connected to the first end of the switch unit, the second control end of the micro control unit may be connected to the second end of the switch unit, when the enabling end of the backlight module is at a high level, the backlight module may be in a lit state, and when the enabling end of the backlight module is at a low level, the backlight module may be in a extinguished state.

Based on this, the micro control unit generates the first control signal, which may mean that the second control end of the micro control unit outputs a high level signal, and the micro control unit sends the first control signal to the switch unit, which may mean that the micro control unit outputs the high level signal to the second end of the switch unit through the second control end, and the switch unit may control the first end of the switch unit to be at a low level after receiving the high level signal, so that the enabling end of the backlight module may be at a low level, at this time, the level state of the enabling end of the backlight module is not controlled by the level signal output by the first control end, which is equivalent to that the communication loop between the screen motherboard and the backlight module is disconnected, the backlight module may be in an off state, and when the central control screen is updated, the micro control unit may continuously output the high level signal to the second end of the switch unit, so that the backlight module maintains the off state.

Wherein, the low level may refer to a voltage less than 30% of the power supply voltage of the micro control unit, the high level may refer to a voltage greater than 70% of the power supply voltage of the micro control unit, for example, the power supply voltage is 5V, the voltage judgment threshold of the low level may be determined to be 1.5V, and the voltage judgment threshold of the high level may be determined to be 3.5V, the low level may be determined when the voltage is less than 1.5V, and the high level may be determined when the voltage is greater than 3.5V; the embodiment of the application does not limit the voltage judgment threshold values of the low level and the high level, and can be set according to actual conditions.

Step S130, when the notification signal is the keep-alive signal, a second control signal is generated in response to the keep-alive signal, and the second control signal is sent to the switch unit to control the switch unit to conduct the communication loop between the screen main board and the backlight module, so that the screen main board controls the working state of the backlight module.

Before the screen main board receives the update data packet, the screen main board can be kept in a normal running state, the state of the central control screen update process can include that the central control screen is in an update ready state, the central control screen is in an update state and the central control screen is in a restart state after update, and the central control screen can be in a normal running state again after the central control screen is restarted.

Based on this, according to the connection relationship, the micro control unit generates the second control signal, which may mean that the second control end of the micro control unit outputs the low level signal, the micro control unit sends the second control signal to the switch unit, which may mean that the micro control unit outputs the low level signal to the second end of the switch unit through the second control end, after the switch unit receives the low level signal, the level state of the first end of the switch unit is controlled by the level signal output by the first control end of the screen motherboard, at this time, the level state of the enabling end of the backlight module is controlled by the level signal output by the first control end, which corresponds to that the communication loop between the screen motherboard and the backlight module is conductive, when the first control end outputs the high level signal, the enabling end is in the high level state, the backlight module may be in the on state, and when the first control end outputs the low level signal, the enabling end is in the low level state, and the backlight module may be in the off state, so that the working state of the screen motherboard control module can be realized, i.e. the working state of the backlight module is controlled by the central control screen.

Specifically, when the central control screen is in a normal running state, the screen main board can output a PWM control signal through the first control end, and the driving voltage of the backlight source in the backlight module is adjusted based on the PWM control signal, so that the brightness of the backlight module can be accurately adjusted.

Based on the method, when the central control screen is ready to be updated, the screen main board can send an update forenotice signal to the micro control unit, the micro control unit can generate a first control signal and send the first control signal to the switch unit after receiving the update forenotice signal so as to control the switch unit to disconnect a communication loop between the screen main board and the backlight module, the central control screen can not control the brightness of the backlight module, when the central control screen is updated, the screen main board can send a keep-alive signal to the micro control unit, the micro control unit can generate a second control signal and send the second control signal to the switch unit after receiving the keep-alive signal so as to control the switch unit to conduct the communication loop between the screen main board and the backlight module, and the central control screen can control the brightness of the backlight module again.

In addition, referring to fig. 2, in an embodiment, after step S120 in the embodiment shown in fig. 1, the following steps are included, but not limited to:

Step S210, continuously detecting whether a keep-alive signal is received;

step S220, if the detection result indicates that the keep-alive signal is not received, a first control signal is sent to the switch unit again;

in step S230, if the detection result indicates that the keep-alive signal is received, a second control signal is generated in response to the keep-alive signal, and the second control signal is sent to the switch unit.

After the micro control unit receives the update advance notice signal, the micro control unit can determine that the central control screen is in an update process, the screen main board does not send a keep-alive signal to the micro control unit, when the update process of the central control screen is finished, namely, when the central control screen is restarted, the central control screen is in a normal running state, so that the screen main board can send the keep-alive signal to the micro control unit, after the micro control unit receives the update advance notice signal, the micro control unit can continuously detect whether the keep-alive signal is received, when a detection result indicates that the micro control unit does not receive the keep-alive signal, the micro control unit can determine that the central control screen is still in the update process, and continuously send a first control signal to the switch unit, so that the backlight module is kept in an off state, energy consumption of an intelligent home system can be reduced, non-inductive upgrading of the central control screen can be realized, sleeping of a customer is avoided, and use experience of the customer is improved.

Based on the above, after the micro control unit receives the update advance notice signal, when the micro control unit receives the keep-alive signal for the first time, the micro control unit can determine that the central control screen is updated, and the micro control unit can send a second control signal to the switch unit, so that the screen main board can control the working state of the backlight module.

In addition, referring to fig. 3, in an embodiment, after step S130 in the embodiment shown in fig. 1, the following steps are included, but not limited to:

step S310, detecting whether a keep-alive signal is received or not in a preset period;

step S320, if the detection result indicates that the keep-alive signal is not received within the preset period, a restart signal is generated, and the restart signal is sent to the screen motherboard, so that the screen motherboard is restarted.

It can be understood that after the micro control unit receives the keep-alive signal, the micro control unit can determine that the central control screen is in a normal operation state, when the central control screen can be configured to be in the normal operation state, the screen main board can send the keep-alive signal to the micro control unit at intervals, which is equivalent to that the screen main board can send the keep-alive signal to the micro control unit in a preset period, that is, the screen main board can send a dog feeding signal to the micro control unit at intervals, and the dog feeding signal can also be called a heartbeat signal; the micro control unit may be configured to determine that the central control screen is in a down state if the keep-alive signal sent by the screen main board is not received within a preset period after determining that the central control screen is in a normal operation state, that is, determining that the central control screen cannot work normally, and the micro control unit may generate a restart signal and send the restart signal to the screen main board, which is equivalent to sending a reset signal to the screen main board, where the screen main board may be reset and restarted, and the central control screen may reenter the normal operation state after restarting.

For example, the preset period is set to 60 seconds, when the central control screen is in a normal running state, the micro control unit can receive the keep-alive signal from the screen main board every 60 seconds, if the period exceeds 60 seconds, the micro control unit does not receive the keep-alive signal sent by the screen main board, determines that the central control screen is in a downtime state, generates a restart signal, and sends the restart signal to the screen main board to reset the screen main board.

Specifically, the screen main board is provided with a GPIO end and a reset end, the micro control unit is provided with a detection end and a reset control end, the GPIO end is electrically connected with the detection end, the reset end is electrically connected with the reset control end, the screen main board can send a keep-alive signal to the micro control unit through the GPIO end, the micro control unit can control the reset control end to output a restart signal to the reset end, and when the screen main board receives the restart signal, the screen main board can reset and restart.

Based on this, the micro control unit can effectively detect that the well accuse screen is in normal operating condition or downtime state, and when the well accuse screen was in downtime state, can in time send the restart signal to the screen mainboard for the screen mainboard can reset and restart, and well accuse screen resumes normal work, avoids influencing customer's normal use, thereby improves customer's use experience.

In addition, referring to fig. 4, in an embodiment, the update advance notice signal carries the update time of the central control screen, and the method for updating the smart home system further includes, but is not limited to, the following steps:

step S410, analyzing the update advance notice signal to obtain update time;

step S420, generating a first control signal when the current time reaches the update time;

step S430, a first control signal is sent to the switching unit.

After receiving the update data packet, the central control screen can select a proper update time to update, so that the use of a client is prevented from being influenced by the update of the central control screen, therefore, the screen main board can firstly determine the update time and then generate an update advance notice signal carrying the update time, the central control screen can be in a normal working state before the update time is reached, and the central control screen can enter the update state when the update time is reached.

For example, the central control screen may be configured to update at 2 a.m., the update time is two a.m. each day, and after the central control screen receives the update data packet during the day, the screen main board may use the update time closest to the current time as the current update time, i.e. 2 a.m. the next day, and then generate an update advance notice signal carrying the update time, and send the update advance notice signal to the micro control unit, where when the update data packet received during the day reaches 2 a.m. the next day, the central control screen updates based on the update data packet received during the day.

Based on the method, the micro control unit can receive the update advance notice signal carrying the update time, the update time determined by the screen main board can be determined by analyzing the update advance notice signal, when the update time is reached, the central control screen enters an update state, at the moment, the micro control unit needs to generate a first control signal and send the first control signal to the switch unit, so that the backlight module can be kept in an off state when the central control screen is updated, the energy consumption of the intelligent home system can be reduced, the noninductive upgrading of the central control screen can be realized, the sleeping of a customer is avoided, and the use experience of the customer is improved.

In addition, referring to fig. 5, in an embodiment, the smart home system further includes a smart home device electrically connected to the micro control unit, and the smart home system updating method further includes, but is not limited to, the following steps:

step S510, receiving a device control instruction from a screen main board;
