Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a lamp tube coding structure and an automatic identification method thereof as shown in figures 1-4, which mainly comprise a lamp head, a lamp post, a microcontroller and the like, and is shown in figure 1 below. The lamp holder can be directly connected with various lamps such as a common illuminating lamp, a laser lamp and the like, and the lamp post is connected with the lamp holder through a power line. The lamp post comprises a storage chip (W25Q128 or AT24C02 and other storage chips) and a coding circuit PCB, a signal line of the coding circuit is connected with a microcontroller, and the microcontroller (STM32) can read and modify data of the storage chip in the lamp post through a certain communication mode (SPI or IIC communication mode).

The lamp post is composed of four parts, namely a lamp shell, a radiating fin, a storage chip and a coding circuit PCB. The lamp shell is an outermost wrapping layer and is used for wrapping and fixing the lamp cap and the circuit board. Because the lamp can continuously generate heat if the lamp works for a long time or the power is high, the radiating fins are close to the position of the lamp, and the heat is conveniently and quickly radiated. The storage chip is used for storing parameters such as the model number, the color, the voltage, the current and the like of the lamp, and the microcontroller (STM32) can add and modify the corresponding parameters according to actual needs. The self-made coding circuit consists of a normal working circuit for driving the lamp, a storage chip driving circuit, a microcontroller control circuit and the like, and aims to enable the microcontroller to identify the type of the lamp and drive the lamp to work normally according to the working parameters of the type of the lamp.

As shown in figure 2 below: the left side is the lamp pins, the middle is the self-made circuit board, and the right side is a row of pins for connecting with the microcontroller. The lamp post and the lamp are integrated or separated, and the lamp post and the microcontroller are separated to support plug-in type. If the lamp is broken, the user can replace the lamp only by simple plugging and unplugging, and the lamps of different types can be replaced, because the lamp is provided with the storage chip, the microcontroller can drive the lamps of different types to normally work according to the parameters of the storage chip.

As shown in the system block diagram of fig. 3 below, the dashed line box is an integral and may not be separated, and the lamp head and the dashed line box may be an integral and may also be separated, and the lamp head and the dashed line box may be referred to as a lamp with code (coded lamp). The lamp with the code and the microcontroller are separable, and the connection mode of the lamp and the microcontroller is a plug-in mode, so that the lamp is convenient to replace. Firstly, the coded lamp is that the microcontroller writes the relevant operating parameters of the lamp into the memory chip of the lamppost in advance. The process of coding the lamp is generally finished when the lamp with the code leaves a factory, and the lamp is supported to be changed by a user in actual use after leaving the factory, but the user is generally not advised to change the parameters of the storage chip in the lamp post at will, so that each lamp has the relevant working parameters when leaving the factory. Then, the user inserts the coded lamp into a microcontroller with a lamp socket, the microcontroller reads the data of the lamp post memory chip once every certain time interval (such as 50 milliseconds) in the process of executing the program, and the microcontroller processes the data read from the memory chip to control the normal operation of the lamp. The microcontroller thus accomplishes the identification and control of the different types of lamps.

The microcontroller program executes the following system flowchart shown in fig. 4, and after the program initialization is completed, a time slice (for example, 50 milliseconds) is set, and the reading of the data of the lamp tube memory chip, the processing of the data to obtain the data of the control lamp tube, the driving of the lamp operating program and other user programs are respectively completed in the time slice. Because the program always reads the data stored in the lamp chip in a loop, hot plugging is supported, i.e. the power can not be cut off in the process of replacing the lamp. Thus, the flexibility is high, and the replacement operation is very convenient.

The light supplement lamp for plant growth is described as an example.

The plant growth light supplement lamp is formed by matching a plurality of blue laser lamps with the wavelength of 460 +/-40 nm and a plurality of red laser lamps with the wavelength of 680 +/-40 nm according to a certain proportion (such as 12 red lamps and 3 blue lamps, the proportion of the lamps is 4: 1). Because the illumination that different plants need all is different, so the proportion collocation of blue light red light, specific proportion can carry out reasonable selection according to actual conditions, and the selection with the power size also has the difference. Therefore, the plant growth light filling lamp needs to have a connection mode which supports convenient disassembly and replacement, and the pluggable connection mode needs to be physically firm and good in electrical contact. In addition, the microcontroller can automatically recognize and control the operation of the blue light and the red light. Thereby reach the collocation proportion that the user need adjust blue lamp and red light, only need pull down the red light and trade blue lamp or the blue light is pulled down and trades the red light and can accomplish the adjustment of collocation proportion, vegetation light filling lamp just can normally work, does not need the user to carry out too many loaded down with trivial details operations, also can reduce the error rate of changing simultaneously to raise the efficiency greatly, make vegetation light filling lamp become more nimble and intelligent.

The plant growth fill light can be composed of 3 460nm blue laser lamps and 12 660nm red laser lamps arranged according to 5 x 3. The rated voltage of the blue lamp is 6V, and the rated power is 80 mW; rated voltage is 5V and rated power is 120mW when the lamp is at red. The blue light and the red light can all pass through the self-control circuit as shown in 2, namely the memory chip and the peripheral circuit thereof, and the microcontroller controls the brightness of the blue light and the red light in a PWM mode. The ratio of the blue light to the red light is not limited to the above ratio.

According to the requirement of the attached drawings of the invention, the self-made lamp tube comprises: the lamp holder is connected with a blue lamp (red lamp), and the lamp post comprises an AT24C02 memory chip, a self-made circuit board, a heat sink and a lamp shell. The self-made lamps are integrated into a whole, and are hereinafter referred to as lamps.

According to the requirements of the drawing, the microcontroller can select STM32, and the communication mode can select IIC protocol. This part and self-control vegetation light filling lamp PCB as an organic whole, hereinafter called the mainboard. The main board is provided with 15 sockets for the lamp tubes, and the sockets can be connected with the red lamp tubes or the blue lamp tubes.

The lamp tube and the main board are two mutually independent bodies. The mounting, dismounting and replacing modes only need to insert the lamp tube on the main board, and the adjustment of the matching proportion of the red lamp and the blue lamp can be completed only by pulling the lamp on the lamp tube and inserting the lamp in the lamp tube. If the fluorescent tube on the mainboard has burnt or has bad, only need to dismantle the fluorescent tube that bad get off install again go can, STM32 reads fluorescent tube memory chip's data automatically through the IIC agreement to carry out automatic control to the lamp, need not too much loaded down with trivial details operation, it is very convenient to the maintenance in later stage.

The method for automatically identifying the lamp tube of the plant light supplement lamp main board is that STM32 reads information of a coding chip in the lamp tube through an IIC communication protocol in each program operation period, and then controls the state, the brightness and the color and brightness matching proportion of the lamp. The brightness of the lamp is that STM32 changes the power of the lamp by adjusting the size of the PWM duty cycle, the PWM duty cycle of 100% represents the full power operation of the lamp, the PWM duty cycle of 0% represents the lamp to go out, and the brightness change of the lamp is realized by adjusting the PWM duty cycle from 1% -100%. The lamp color and brightness matching proportion is adjusted in such a way that the numbers of the red lamps and the blue lamps on the main board of the plant light supplementing lamp are fixed, and the brightness proportion of each red lamp and each blue lamp is changed, so that the color and brightness proportion of the red lamps and the blue lamps of the whole plant light supplementing lamp is changed. If the number proportion of the red lamps and the blue lamps on the plant light supplementing lamps needs to be changed, the lamp tubes need to be replaced manually.

For example, there are 15 lamps on a plant light supplement lamp mainboard, wherein 12 red lamps are provided, 3 blue lamps are provided, that is, the ratio of the number of the red lamps to the number of the blue lamps is 4:1, if the ratio needs to be changed to 2:1, 2 red lamps need to be manually changed to the blue lamps, and thus 10 red lamps and 5 blue lamps are changed. The light color and brightness matching proportion is that the number ratio (such as 4:1) of red light and blue light is fixed on the main board of the plant light supplement lamp, and if the current red light duty ratio is 60% and the current blue light duty ratio is 30%, the light color and brightness matching proportion is 2: 1. If the ratio of the brightness is to be changed to 3:1, the duty ratio of the red light can be adjusted to 90% or the duty ratio of the blue light can be adjusted to 20%, so as to change the ratio of the color and brightness matching of the light. The data of this example is only one proportion data of the plant fill light, and is also applicable to other proportion data.

The method comprises the following steps:

the lamp tube is programmed into relevant information of the lamp in the storage chip in the lamp tube when the lamp tube leaves a factory, and a user can modify corresponding data of the storage chip through corresponding operation before the lamp tube is installed on the plant growth light supplement lamp or the user can properly increase some required parameters according to needs. If the work is set from 6 pm to 5 am on monday weekly, this is just a simple explanation, and the user actually sets the work.

After the blue light and red light tubes are matched according to a certain ratio, the STM32 can automatically execute a corresponding program to control the plant growth light supplementing lamp after power is on. The STM32 can be adjusted by reading data of AT24C02 memory chip in the lamp tube by IIC to identify whether the lamp is red or blue, and the working voltage and current are needed, and according to user adjustment, when the blue lamp and the red lamp are on or off, and the brightness is needed. The intelligent control lamp has the characteristics of simple operation, flexible matching proportion and intelligent control.

After long-time operation, the blue lamp or the red lamp possibly has the service life, and is very convenient to replace. The user only needs simple dismantlement vegetation light filling lamp's shell screw, then directly pulls out bad fluorescent tube, inserts good fluorescent tube, then can accomplish the maintenance to the tight shell screw of turning round of light filling lamp. The plant growth light supplement lamp can continue to work normally.
