The scanning method is a circuit control method for controlling a plurality of LEDs by simultaneously lighting the ratio of the number of rows to the number of rows in the whole area, and is a commonly used LED control method in the art. Optionally, the LED scanning mode of the present application is dynamic scanning. In addition, the present application is related to a program for controlling a plurality of indicator lamps of the fire indicator lamp group 200 by an LED scanning method.

Optionally, the operation mode of the fire indicator lamp set 200 provided by the application is specifically as follows:

When the barbecue oven knob is electrified, the main control module U1 controls the first status indicator lamp LED1 to be lightened, and meanwhile, the main control module U1 sequentially lightens the first fire indicator lamp LED2, the second fire indicator lamp LEDs 3 and …, the twelfth fire indicator lamp LED14 and the third status indicator lamp LED15 according to the sequence. Then, the main control module U1 sequentially extinguishes the third status indicator LED15, the twelfth fire indicator LED14, …, the second fire indicator LED3, and the first fire indicator LED2. That is, the main control module U1 sequentially lights the first to third fire indicator LEDs 2 to 15 in the form of a ticker, and sequentially extinguishes the third to first fire indicator LEDs 15 to 2 in the form of a ticker. It should be noted that, the program related to the main control module controlling the indication lamp in the form of the horse race lamp is a common program in the field, and the program belongs to the prior art.

Under the condition that the rotating part 110 and the fixed part 120 do not rotate relatively, the rotation angle of the encoder U2 is 0 degrees, and the main control module U1 controls the first status indicator light LED1 to be turned on so as to indicate that the barbecue oven is not turned on.

When the rotating portion 110 and the fixing portion 120 rotate relatively, the rotation angle is a certain angle, and the direction is clockwise, that is, when the encoder U2 rotates clockwise, each rotation of one case extinguishes one indicator lamp, one case corresponds to one rotation angle, and the extinguishing sequence is arranged as follows: a third status indicator lamp LED15, a twelfth fire indicator lamp LED14, eleventh fire indicator lamp LEDs 13, …, a fourth fire indicator lamp LED5, a third fire indicator lamp LED4, a second fire indicator lamp LED3, and a first fire indicator lamp LED2.

When the rotating portion 110 and the fixing portion 120 rotate relatively, the rotation angle is a certain angle, and the direction is counterclockwise, that is, when the encoder U2 rotates in the counterclockwise direction, each rotation of one cell lights an indicator lamp, one cell corresponds to one rotation angle, and the lighting sequence is ordered as follows: a first fire indicator lamp LED2, a second fire indicator lamp LED3, a third fire indicator lamp LED4, …, an eleventh fire indicator lamp LED13, a twelfth fire indicator lamp LED14, and a third status indicator lamp LED15.

Based on the above embodiment, the working principle of the application for realizing fire synchronization indication is as follows:

after the fixing portion 120 of the knob body 100 is connected with an external barbecue oven, the user rotates the knob body 100 at a certain angle and direction, so that the rotating portion 110 and the fixing portion 120 rotate relatively, and the fire power of the barbecue oven can be increased or reduced, so that the barbecue oven is located in a fire gear required by the user. The mode of increasing or decreasing the fire power of the barbecue oven is the same as the control mode of the existing gas stove. The existing gas stove control mode is that when a knob is rotated anticlockwise and the rotation angle is between 0 and 90 degrees, the fire power of the gas stove is increased, and when the knob is rotated clockwise and the rotation angle is between 0 and 90 degrees, the fire power of the gas stove is reduced. When the rotation angle of the knob is 90 degrees, the fire power of the gas stove is maximum. When the knob is rotated counterclockwise and the rotation angle is an angle between 90 and 180 degrees, the fire power of the gas stove is reduced, and when the knob is rotated clockwise and the rotation angle is an angle between 90 and 180 degrees, the fire power of the gas stove is increased. When the rotation angle of the knob is 180 degrees, the fire power of the gas stove is minimum.

Because the rotating part 110 is connected with the main shaft of the encoder U2, and the main shaft of the encoder U2 is connected with the valve rod, and the valve rod is connected with the gas valve of the barbecue oven, the rotation of the rotating part 110, the rotation of the encoder U2 and the rotation of the valve rod are all synchronous rotation. The rotation direction and the rotation angle of the encoder U2 map the fire power of the current barbecue oven, and the main control module U1 controls the fire power indication lamp group 200 to synchronously indicate according to the rotation angle of the encoder U2.

Alternatively, the fire power gear of the barbecue oven may be divided into seven gears. Under the condition that the rotating part 110 and the fixed part 120 do not rotate relatively, the rotation angle of the encoder U2 is 0 degrees, and the main control module U1 controls the first status indicator light LED1 to be turned on so as to indicate that the barbecue oven is not turned on.

When the rotation portion 110 and the fixed portion relatively rotate, the following is classified as follows:

when the rotation angle of the encoder U2 is smaller than 90 ° and larger than 0 °, the barbecue oven is already turned on and its fire corresponds to the rotation angle of the encoder U2. Wherein, when the user rotates the knob counterclockwise, the encoder U2 rotates counterclockwise in synchronization, and the rotation angle of the encoder U2 increases. According to the principle of the existing gas stove control mode, when the rotation angle of the knob is smaller than 90 degrees and larger than 0 degrees, the firepower of the barbecue stove is increased when the knob rotates anticlockwise. Under the control of the main control module U1, the first status indicator light LED1 keeps on, and when the rotation angle of the encoder U2 increases, the number of the on lights of the first indicator light group 210 increases, and the fire power of the barbecue oven increases.

When the user rotates the knob clockwise, the encoder U2 rotates clockwise, and the rotation angle of the encoder U2 decreases. According to the principle of the existing gas stove control mode, when the rotation angle of the knob is smaller than 90 degrees and larger than 0 degrees, the firepower of the barbecue oven is reduced when the knob rotates clockwise. Under the control of the main control module U1, the first status indicator light LED1 keeps on, and when the rotation angle of the encoder U2 is reduced, the number of the on lights of the first indicator light group 210 is reduced, and the fire power of the barbecue oven is reduced.

It should be emphasized that the greater the number of lights of the first light set 210, the greater the fire of the barbecue grill.

More specifically, when the rotation angle of the encoder U2 is the first angle, the barbecue oven is turned on and the fire gear thereof is the first gear, and the main control module U1 controls the first status indicator light LED1 and the first fire indicator light LED2 to be turned on to indicate that the fire gear of the barbecue oven is the first gear.

When the rotation angle of the encoder U2 is the second angle, the barbecue oven is started, the fire gear of the barbecue oven is the second gear, and the main control module U1 controls the first status indicator lamp LED1, the first fire indicator lamp LED2 and the second fire indicator lamp LED3 to be lightened so as to indicate that the fire gear of the barbecue oven is the second gear.

When the rotation angle of the encoder U2 is the third angle, the barbecue oven is started, the fire gear is the third gear, and the main control module U1 controls the first status indicator lamp LED1, the first fire indicator lamp LED2, the second fire indicator lamp LED3 and the third fire indicator lamp LED4 to be lighted so as to indicate that the fire gear of the barbecue oven is the third gear.

When the rotation angle of the encoder U2 is the fourth angle, the barbecue oven is started, the fire gear of the barbecue oven is the fourth gear, and the main control module U1 controls the first status indicator lamp LED1, the first fire indicator lamp LED2, the second fire indicator lamp LED3, the third fire indicator lamp LED4 and the fourth fire indicator lamp LED5 to be lighted, so that the fire gear of the barbecue oven is indicated to be the fourth gear.

When the rotation angle of the encoder U2 is the fifth angle, the barbecue oven is started and the fire gear is the fifth gear, and the main control module U1 controls the first status indicator lamp LED1, the first fire indicator lamp LED2, the second fire indicator lamp LED3, the third fire indicator lamp LED4, the fourth fire indicator lamp LED5 and the fifth fire indicator lamp LED6 to be lighted so as to indicate that the fire gear of the barbecue oven is the fifth gear.

When the power supply controller U3 is connected, the power supply controller U3 supplies power to the main control module U1, and the main control module U1 is electrified.

In some embodiments of the present utility model, the surface of the rotating portion 110 is provided with a backlight 111, and the main control module U1 is provided with a first output end PA3, where the first output end PA3 is electrically connected to the backlight 111.

Further, referring to fig. 3, the integrated circuit on the control circuit board is further integrated with a first transistor Q1 and a first resistor R1. The base of the first triode Q1 is connected to the first output terminal PA3 through the first resistor R1, the emitter thereof is connected to the ground terminal, the collector thereof is connected to the negative electrode of the backlight 111, and the positive electrode of the backlight 111 is pulled to an external voltage. The main control module U1 controls the operation of the backlight 111 by configuring the first output terminal PA3 to an output mode.

The backlight 111 is a light emitting diode, and the first transistor Q1 is an NPN transistor.

The first resistor R1 is used for limiting current, so as to prevent the first triode Q1 from being burnt out due to overlarge current flowing into the first triode Q1. Alternatively, the external voltage is provided by the power supply controller U3.

In this embodiment, the purpose of the backlight 111 is to indicate the condition of the oven knob being powered on, and when the oven knob is powered on, the backlight 111 operates to indicate the oven knob is powered on. The main control module U1 is configured to control the operation of the backlight 111 when powered on. Specifically, the backlight 111 is a light emitting diode, and when the positive electrode thereof is at a high level and the negative electrode thereof is at a low level, the backlight 111 operates. When its positive electrode is high and its negative electrode is high, the backlight 111 does not operate. When the power controller U3 is connected to the main control module U1, the main control module U1 is powered on, the first output terminal PA3 outputs a low level signal, the base of the first triode Q1 is low level and turned off, the negative electrode of the backlight 111 is low level, and the backlight 111 is operated and kept normally on. When the power controller U3 is disconnected from the main control module U1, the main control module U1 is powered off and the backlight 111 does not operate.

In some embodiments of the present utility model, referring to fig. 3, the action of the rotating portion 110 further includes pressing a press KEY. Pressing KEY is the KEY of encoder U2. The pressing KEY is electrically connected with the pressing detection end PA4 of the main control module U1. The main control module U1 detects the pressing condition of the pressing KEY by configuring the pressing detection terminal PA4 as an input mode. When the KEY is pressed, it can be regarded that the KEY is closed; when the KEY is not pressed, it can be regarded as the KEY is disconnected.

Typically, when opening the barbecue oven, it is often necessary to press down and rotate the knob to open the barbecue oven to a certain working position. The present utility model also provides a backlight 111 for indicating the pressing of the knob body 100. When the knob body 100 is pressed, the barbecue oven is turned on, and the main control module U1 controls the backlight 111 to barbecue and flash to indicate that the barbecue oven body is pressed. There are two cases where the knob body 100 is not pressed: one is that after the barbecue oven is opened by pressing the barbecue oven knob, the barbecue oven knob is not pressed; the other is that when the barbecue oven is not opened, the barbecue oven knob is not pressed. Regardless of which barbecue grill is not pressed, when the main control module U1 detects that the barbecue grill is not pressed, it controls the backlight 111 to remain normally on to indicate that the barbecue grill body is not pressed.

When the knob body 100 is pressed, the main control module U1 changes the level signal output from the first output terminal PA3 thereof at a certain frequency according to the pressing of the KEY. The specific implementation process is as follows: the main control module U1 intermittently outputs a high-level signal and a low-level signal to the first triode Q1 through the first output end PA3 thereof, and the first triode Q1 is also turned on or off at a certain frequency, so that the negative electrode of the backlight 111 is changed between the high level and the low level at a certain frequency, and the effect of flickering of the backlight 111 is achieved.

It should be noted that, the intermittent output refers to that the main control module U1 outputs a high level signal to the first transistor Q1 for a period of time, then outputs a low level signal to the first transistor Q1 for another period of time, and then outputs a high level signal to the first transistor Q1 for a period of time, and so on.
