Detailed Description

The embodiment of the application provides a light stimulation system, and solves the technical problems that in the prior art, a laser is expensive in manufacturing cost and complex in equipment, so that the equipment cost is high and the experimental purpose is not easy to achieve.

In order to solve the technical problems, the general idea of the embodiment of the application is as follows:

a light stimulation method applied to a controller, the controller being disposed in a light stimulation system, the light stimulation system further comprising: the LED light source is in communication connection with the controller, the LED light source is connected with a controlled object, photosensitive protein is arranged in the controlled object, and the method comprises the following steps: receiving control parameters for adjusting the motion state of the controlled object; acquiring a target value of a target instruction zone bit corresponding to the control parameter, wherein the target instruction zone bit is one or more of a plurality of instruction zone bits for driving the LED light source; and when the target value is a preset value, driving the LED light source to execute an operation corresponding to the control parameter according to the control parameter so as to stimulate photosensitive protein in the body of the controlled object and control the movement of the controlled object.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

Example one

The present embodiment provides a light stimulation method, as shown in fig. 1, which is a flowchart of the light stimulation method provided in the embodiments of the present specification, and is applied to a controller, where the controller is disposed in a light stimulation system, and the light stimulation system further includes: the LED light source is in communication connection with the controller, the LED light source is connected with a controlled object, photosensitive protein is arranged in the controlled object, and the method comprises the following steps:

step S101: receiving control parameters for adjusting the motion state of the controlled object;

step S102: acquiring a target value of a target instruction zone bit corresponding to the control parameter, wherein the target instruction zone bit is one or more of a plurality of instruction zone bits for driving the LED light source;

step S103: and when the target value is a preset value, driving the LED light source to execute an operation corresponding to the control parameter according to the control parameter so as to stimulate photosensitive protein in the body of the controlled object and control the movement of the controlled object.

In the specific implementation process, step S101 is first executed: and receiving control parameters for adjusting the motion state of the controlled object.

Specifically, the controlled object may be a small animal such as a pigeon, and the control parameters may include various parameters, such as: the starting control parameters of the LED light source, the pulse waveform adjusting parameters of the LED light source, the closing control parameters of the LED light source and the like. The LED light source can be controlled to perform different operations through the control parameters, so that the controlled object can be controlled to perform a series of movements, such as controlling a pigeon to perform running, jumping, spreading wings and the like.

As an alternative embodiment, after the receiving the control parameter for adjusting the motion state of the controlled object, step S101 further includes:

determining a target length of the control parameter;

determining a driving instruction corresponding to the target length based on the target length and a preset relation between the parameter length and the driving instruction;

and setting the value of the instruction zone bit corresponding to the driving instruction as the preset value.

In the specific implementation process, the preset relationship between the parameter length and the driving instruction may be preset, and the corresponding parameter lengths may be different for different driving instructions. In this embodiment, the driving instruction may include an instruction to start the LED light source, an instruction to turn off the LED light source, an instruction to adjust parameters of the LED light source, and the like. The parameter length corresponding to each driving command may be set according to actual needs, for example, the parameter length corresponding to the start command of the LED light source may be 35 bytes, and the parameter length corresponding to the off command of the LED light source may be 40 bytes.

And after receiving the control parameters, determining the target length of the control parameters, and determining the driving instructions corresponding to the received control parameters based on the preset relationship between the parameter length and the driving instructions. Still using the above example, if the target length of the received control parameter is 35 bytes, it can be determined that the driving instruction corresponding to the control parameter is the start instruction of the LED light source through the preset relationship, and further, the instruction flag bit corresponding to the start instruction of the LED light source is set to the preset value. Specifically, the preset value may be set according to actual needs, for example, the preset value is 1.

In addition, if the target length is not found in the preset relationship between the parameter length and the driving instruction, the control parameter may be cleared and information may be returned to the background controller, for example: the control terminal clears the control parameter and returns information such as 'the parameter length is illegal, please re-input' and the like to the background controller.

As an alternative embodiment, before the determining the target length of the control parameter, step S101 further includes: and detecting whether a tail frame of the control parameter is received, and if the tail frame is received, executing the step of determining the target length of the control parameter.

Specifically, the code end of each control parameter carries an end frame, and after receiving the control parameter, it needs to detect whether the control parameter carries the end frame, and then performs the next operation after detecting the end frame. For example: the tail frame of the control parameter is set to 0100, when a control parameter is received, the system detects the control parameter byte by byte, the control parameter is stopped to be received until 0100 is received, and then the target length of the received control parameter is judged.

Further, step S102 is executed: and acquiring a target value of a target instruction zone bit corresponding to the control parameter, wherein the target instruction zone bit is one or more of a plurality of instruction zone bits for driving the LED light source.

In step S102, each control parameter has a corresponding instruction flag bit, and there may be a plurality of control parameters, such as: the starting control parameters of the LED light source, the pulse waveform adjustment parameters of the LED light source, the closing control parameters of the LED light source and the like, and the corresponding instruction zone bits can be respectively as follows: a start flag, a light source adjustment flag, a shut down flag, etc. For each instruction flag bit, the instruction flag bit may have a plurality of state values, and taking the instruction flag bit having two state values as an example, if the value of the instruction flag bit is 1, the representation needs to execute the corresponding instruction according to the control parameter, and if the value of the instruction flag bit is 0, the corresponding instruction is not executed.

In the embodiment of the present specification, after the control parameter is acquired, the target value of the target instruction flag corresponding to the control parameter is determined, for example, when the start control parameter of the LED light source is acquired, the current value of the start flag is read as the target value.

Further, step S103 is performed: and when the target value is a preset value, driving the LED light source to execute an operation corresponding to the control parameter according to the control parameter so as to stimulate photosensitive protein in the body of the controlled object and control the movement of the controlled object.

In a specific implementation process, a preset value of the instruction flag bit may be set according to actual needs, where the preset value may be any one of state values included in the instruction flag bit, and in this embodiment of the present specification, a state value used for representing an instruction corresponding to an execution control parameter is used as a target value. Taking the target value as 1 as an example, the control parameter is a parameter for controlling the controlled object to run, and when the value of the corresponding instruction flag bit is 1, the LED light source is driven to emit a light signal corresponding to the control parameter, and the light signal stimulates the photosensitive protein implanted in the controlled object, so as to control the controlled object to run.

The photosensitive protein is a protein, and a photosensitive ion channel expressed on a nerve cell can respond to a light signal with specific wavelength and intensity, so that specific ions pass through the photosensitive protein, the potential on two sides of a cell membrane is changed, the nerve cell is accurately activated or inhibited, and the effect of controlling a controlled object to perform various motions is further realized.

As an alternative embodiment, in step S103, driving the LED light source to perform an operation corresponding to the control parameter according to the control parameter includes: detecting whether the parameter value of the control parameter is within a preset parameter range; and if so, driving the LED light source to execute the operation corresponding to the control parameter according to the control parameter.

Specifically, the control parameters have a preset parameter range for protecting the system and the device. Before the LED light source is driven according to the control parameters, whether the control parameters are within a preset parameter range or not is detected, and the control parameters which accord with the preset parameter range can be used for driving the light source. For example: the control time of the preset driving parameter is 0-20s, and when the control time of the received driving control parameter is 15s, the driving parameter accords with the preset parameter range.

In order to better understand the scheme of the embodiment of the present invention, as shown in fig. 2 and fig. 3, the present invention provides a flowchart of setting the command flag by the controller and a flowchart of driving the LED light source according to the target value of the command flag by the controller.

Fig. 2 is a flowchart of setting the instruction flag bit by the controller, and the main process is as follows:

301: whether a tail frame is received;

judging whether the end frame of the control parameter is received, for example: if the parameter end frame is 0100, detecting whether a control parameter ending at 0100 is received.

If the control parameter end frame is received, execute 302: checking the length of the parameter;

if no end frame is received, perform 3012: and judging whether the buffer area overflows or not.

Checking the length of the parameter, that is, determining whether the length of the parameter matches a preset length, which is described in detail in this embodiment and is not described herein again; the controller is internally provided with a buffer area, the maximum parameter length is preset in the buffer area, and when the controller does not receive the parameter tail frame, the received parameters are stored in the buffer area.

When the parameter length stored in the buffer area exceeds the preset maximum parameter length, the buffer area overflows, and the following steps are executed 3013: receiving error, and clearing received parameters.

When the parameter length in the buffer does not exceed the maximum parameter length, which means that the buffer does not overflow, 3014: and continuously receiving the parameters and storing the parameters into the buffer area until the tail frame is received.

Executing 303: and judging whether the parameter length meets the preset length.

When the parameter length satisfies the preset length, executing 304: setting the flag bit of the control parameter corresponding to the instruction as a target value;

if the parameter length does not meet the preset length, executing 3031: receiving errors and clearing parameters.

Finally, 305 is executed: the instruction flag is cleared.

Namely, the instruction flag bit set to the target value is cleared.

Fig. 3 is a flowchart of driving the LED light source by the controller according to the target value of the command flag, and the main process is as follows:

first, 401 is executed: the controller is initialized.

Then 402 is executed: detecting an instruction flag bit; 403: whether there is an instruction flag bit set to the target value.

If there is an instruction flag set to the target value, execute 404: and judging the reason why the target instruction flag bit is the instruction.

That is, when the instruction flag is set to the target value, the instruction flag is confirmed as the target instruction flag, and it is further determined which instruction the target instruction flag is, for example: a start instruction, a time control instruction, an end instruction, etc.

If there is no instruction flag set to the target value, then 402 is repeated.

After judging which kind of instruction the target instruction flag bit is, execute 405, 406: checking a parameter range; performing 4051, 4061: whether it passes the check.

Namely, whether the control parameter meets the preset parameter range is judged.

If yes, executing 4052, 4062: and returning an acknowledgement frame.

That is, sending acknowledgement information to the background controller, and then executing 4053: clearing the target value of the instruction zone bit; 4063: the LED starts to be driven.

If the control parameter does not meet the preset parameter range, executing 4053 and 4067: the instruction flag target value is cleared.

After the LED light source starts to be driven, 4064: it is checked whether there is a abort parameter.

I.e. detecting whether there is a parameter suspending the operation of the LED light source.

If not, perform 4065: normally driving the light source until the driving is finished;

if the abort parameter is detected, execute 4066: the driving is suspended.

After the driving is finished, 4067 is executed: the target value on the target instruction flag bit is cleared.

Finally, the process is repeated.

During specific operation, the power supply module of the control terminal supplies power to the controller and the controllable constant current source circuit, and after the controller receives the control parameters, the controller controls the controllable constant current source circuit to supply current to the LED light source according to the control parameters so as to drive the LED light source. The LED light source is driven to generate a light stimulation signal to stimulate the photosensitive protein, and the photosensitive protein receives the light stimulation signal and controls the controlled object to move according to the light stimulation signal.

Further, the background controller is further configured to detect whether the control parameter meets a preset parameter range of the system, and if so, send the control parameter to the control terminal.

Specifically, the background controller packages and sends out the control parameters, judges whether the acquired control parameters are in a preset parameter range or not before the control parameters are packaged, and packages and sends out the control parameters if the acquired control parameters are in the preset parameter range; if not, a message is returned to the user. For example, the preset light power is 0-30 mW, the time is 20s, if the control parameter input by the user is '24 mW, 15 s', the preset parameter range is met, and the background controller packages and sends out the control parameter; if the control parameter input by the user is 34mW and 10s, the control parameter is not in accordance with the preset parameter range, the background controller does not pack the control parameter, and sends information to the user, such as 'input error, please re-input', and the like.

Further, the background controller and the control terminal perform wireless data transmission through Bluetooth.

Specifically, the background controller and the control terminal each include a bluetooth communication module, and the background controller receives the control parameters and then sends the control parameters to the bluetooth communication module of the control terminal through the bluetooth communication module on the background controller.

As an alternative embodiment, the controller 1021 is further configured to: determining a target length of a control parameter; determining a driving instruction corresponding to the target length based on the target length and a preset relation between the parameter length and the driving instruction; and setting the value of the instruction zone bit corresponding to the driving instruction as a preset value.

With regard to the above-mentioned apparatus, the specific functions of the respective units have been described in detail in the embodiments of the optical stimulation method provided in the embodiments of the present specification, and will not be elaborated herein.

As an alternative embodiment, the output light power of the LED light source is 3-10 mW.

Specifically, in the art, optical power of 3mW or more is generally required to open the photosensitive ion channel. When the light power exceeds 10mW, the LED light source will be heated and the body of the controlled object will be damaged if the output power is too large. Therefore, the output light power of the LED light source is set to be 3-10 mW.

As an optional embodiment, the control terminal further includes a driving device, and the driving device is connected to the controller in a pin-row and hole-row manner.

Specifically, in order to minimize the size of the control terminal, the control terminal is divided into a controller and a driving device at the time of design. The controller and the driving device are connected by using pin header holes, namely the controller and the driving device are overlapped up and down, a pin header is arranged on the controller or the driving device, a hole header is arranged on the other device, and then the two devices are connected by using a pin header hole plugging mode.

As an alternative embodiment, the controller is further configured to:

and when the LED light source is driven according to the control parameters, sending the state information of the LED light source to the background controller.

Specifically, the control terminal is wirelessly connected with the background controller, so that a user can know the running state of the control terminal in real time conveniently, and the running state of the LED light source can be sent to the background controller every time the control terminal drives the LED light source. For example: when the control terminal drives the LED light source to start, the background controller is required to send information of the started LED light source.

Further, a stm32f103c8t6 processor is used as the processor of the control device.

In particular, the stm32f103c8t6 processor is the smallest in size, and meets the requirement that the hardware part is designed to be small in size. The function of the system is to receive, check and analyze instructions from a background control program, and then drive a power part to output an optical signal waveform meeting the requirements.

Further, an LM3402 switch chip is adopted as a main power chip of the power device.

Specifically, in order to achieve the dimming effect and take the problem of chromatic aberration into consideration, the power device may adopt an LM3402 switch chip as a main power chip, receive a PWM signal from a microprocessor, and achieve the dimming effect by means of PWM dimming.

With regard to the above-described system, the specific functions of the respective structures and devices have been described in detail in the embodiments of the optical stimulation method provided in the embodiments of the present specification, and will not be elaborated herein.

The technical scheme in the embodiment of the application at least has the following technical effects or advantages:

1. through changing the laser into the LED light source, the technical problems that the laser is expensive in manufacturing cost and complex in equipment in the prior art, so that the experiment cost is high and the experiment purpose is not easy to achieve are solved, and the simplification and the low cost of the animal robot experiment are realized.

4. The output light power of the LED light source is set to be 3-10mW, the LED light source is arranged outside the controlled object body, and the photosensitive ion channel can be opened, and meanwhile, the brain of the controlled object can be prevented from being burned by overlarge output power.
