Background technique

Radiotherapy is a treatment method that uses radiation to treat tumors. Generally, radiation is irradiated to the tumor to cause tumor cell necrosis or apoptosis to achieve the purpose of treating tumors. However, during radiotherapy, if there is a deviation between the irradiation position of the radiation and the position of the tumor, the cells of the healthy organs may be killed by mistake, causing damage to the healthy organs. Therefore, it is very important to locate the tumor location when performing radiotherapy.

Generally, during radiotherapy, the patient's mismovement is an important factor that causes the radiation irradiation position to deviate from the tumor position. For this reason, during radiotherapy, a fixing device is generally used to fix a certain area of the patient, such as Fix the patient's head etc. through the mask.

Although the fixation device can avoid deviations caused by the patient's mismovement, the fixation device may bring other risks due to the inconvenience of the fixation device being detached by the patient and the possibility of blocking the patient. For example, after the patient’s head is fixed with a mask during radiotherapy, if the patient develops symptoms such as vomiting, the patient may not be able to get off the mask in time, so there may be a risk of suffocation due to the vomit; and the presence of the mask makes The treating physician may not be able to detect the symptoms of vomiting in the patient in time, which further increases the risk of suffocation due to the vomit.

Before radiotherapy, obtain the image data of the lower part of the normal state;

In radiotherapy, facial image data is obtained, and if the change in the facial image data is less than a preset threshold, the facial image data is taken as the lower image data in a normal state.

For example, if the preset area is a patient's face, the facial image data includes: entire facial image data or partial facial image data.

For example, the entire facial image data or part of the facial image data is directly collected or obtained by removing the mask.

For example, the partial facial image data obtained by direct collection is partial facial image data obtained through a facial mask incision or partial facial image data obtained through a face without a facial mask attached.

The solution provided by the embodiment of the application realizes the monitoring of the current state of the patient by acquiring the current preset area image data of the patient during the radiotherapy process, and then according to the current preset area image data and the normal state The image data of the preset area can be analyzed to determine the patient’s current state characteristic information, and then generate corresponding control instructions according to the current state characteristic information, and control the radiotherapy system for emergency treatment according to the control instructions, so that during the radiotherapy process, according to The current state of the patient controls the radiotherapy system for emergency treatment, reducing the risk of the radiotherapy process.

The following describes the specific process of the emergency control method in the above-mentioned radiotherapy system through a specific process.

Fig. 2 is a schematic flow chart of the emergency control method in the radiotherapy system in the second embodiment of the application; as shown in Fig. 2, it includes the following steps S201, S202, and S203:

S201: Acquire current preset area image data of the patient during the radiotherapy process.

Radiotherapy is a treatment method that uses radiation to irradiate tumor cells to cause tumor cell necrosis or apoptosis.

The preset area may be an area capable of determining the state of the patient, such as the patient's face, which is not limited in this embodiment.

The current preset area image data can be collected by an imaging device, such as a camera, an infrared imaging device, and so on.

In this embodiment, when the preset area is the patient's face, the distance between the imaging device and the patient's head is within the preset distance range, and can be set above the patient's head.

In the embodiment of the present application, the patient's current preset area image data during the radiotherapy process can be acquired at intervals of a preset time, or the patient's current preset area image data during the radiotherapy process can be acquired in real time. The embodiment of the present application may also perform mean difference calculation or select a better image method according to the obtained image data of multiple preset regions to determine the current preset region image data.

S202: Analyze according to the current preset area image data and the preset area image data in a normal state, and determine the current state characteristic information of the patient.

In this embodiment, the normal state may include the state before the patient undergoes radiotherapy, or the state of the patient normally undergoing radiotherapy.

The patient's current state characteristic information may indicate an emergency state and a non-emergency state, the emergency state includes states such as vomiting, discomfort, and fear, and the non-emergency state includes a calm state.

The image data of the preset area in the normal state may include multiple, and each image data of the preset area in the normal state may correspond to pre-marked state characteristic information, such as emergency state or non-emergency state, or each preset area in the normal state The image data respectively correspond to pre-marked patient states, such as vomiting, uncomfortable, fearful, calm, etc. The image data of the preset area in the normal state may be pre-stored or obtained before the step S202. Therefore, it is possible to analyze the current preset area image data and the preset area image data in a normal state to determine the current state characteristic information of the patient.

Of course, the foregoing is only an example, and other solutions for determining the characteristic information of the current state by analyzing the current preset area image data and the normal state preset area image data are also within the protection scope of this application.

S203: Generate a corresponding control instruction according to the current state characteristic information, and control the radiotherapy system to perform emergency treatment according to the control instruction.

According to the characteristic information of the current state, a control instruction corresponding to the current state of the patient can be generated, and the radiotherapy system can be controlled to perform emergency treatment according to the control instruction, so that an emergency corresponding to the current state of the patient can be performed during the treatment process. Treatment reduces the risk of the radiotherapy process.

For example, if the current preset area image data corresponds to the patient's vomiting, the determined current state characteristic information may be an emergency state, and then a corresponding control instruction may be generated. According to the control instruction, the treatment irradiation of the radiotherapy system may be suspended and controlled. The radiotherapy system allows the patient to turn over so that the patient can easily eliminate the vomit and reduce the risk of suffocation due to the vomit.

The solution provided in this application realizes the monitoring of the patient’s current state by acquiring the patient’s current preset area image data during radiotherapy, and then according to the current preset area image data and the normal state preset The analysis of the regional image data can determine the patient’s current state characteristic information, and then generate corresponding control instructions according to the current state characteristic information, and control the radiotherapy system to perform emergency treatment according to the control instructions, so that during the radiotherapy process, according to the patient’s The current state controls the radiotherapy system for emergency treatment, reducing the risk of the radiotherapy process.

Fig. 3A is a schematic flow chart of the emergency control method in the radiotherapy system in the third embodiment of the application; as shown in Fig. 3A, it includes the following steps S301, S302, S303, and S304:

S301: Acquire image data of a preset area in a normal state.

For example, image data of a preset area under normal conditions can be collected before radiotherapy to form a database corresponding to the patient. Of course, other forms may also be used to store the image data of the preset area in the normal state, which is not limited in this embodiment.

For example, the image data of the preset area may be collected during radiotherapy. If the change of the image data of the preset area is less than the preset threshold, the image data of the preset area is regarded as the image data of the preset area in the normal state. The preset threshold is set by those skilled in the art according to needs or experience.

In addition, the image data of the preset area in the normal state is image data obtained by infrared imaging or a camera. Alternatively, the image data of the preset area in a normal state may be image data of the preset area obtained by analyzing and extracting the patient's life photos, etc., or may be the image data of the preset area determined through big data analysis; Not limited.

For example, the image data of the preset area in the normal state may be indexed, that is, the state of the patient corresponding to the image data of the preset area in the normal state may be marked. The state of the patient may be calm, happy, fearful, uncomfortable, vomiting, etc. Specific indexing can be performed by the treating physician.

For example, the image data of the preset area in the normal state may not be indexed, and in the subsequent steps, the difference between the image data of the current preset area and the image data of the preset area in the normal state may be analyzed to determine the current preset area image data. Set the patient's state corresponding to the regional image data to determine the patient's current state characteristic information. The patient's state can be, for example, calm, happy, fearful, uncomfortable, vomiting, etc.

For example, in this embodiment, the preset area may be the patient's face. Because facial expressions, especially micro-expressions, can more intuitively reflect the patient’s state, setting the preset area as the patient’s face can make the current state characteristic information determined in the subsequent steps correspond to the patient’s facial expressions. As a result, the current state characteristic information can more accurately reflect the current state of the patient, and the emergency treatment performed is more in line with the needs of the patient.

For example, if the preset area is the patient's face, step S301 may include at least one of the following:

In this embodiment, if the change of the facial image data is less than the preset value, it can be considered that the patient is relatively calm, and the facial image data can be used as the facial image data in a normal state.

In addition, in radiotherapy, multiple facial image data can be obtained. If the change of the multiple facial image data is less than a preset value, one of the multiple facial image data can be used as the lower image data in the normal state. For example, one of the plurality of facial image data with better quality may be used as the lower image data in the normal state.

The entire facial image data can be the image data corresponding to the entire face (such as all exposed skin in front of the head), or the image data corresponding to the face that can be collected by the image acquisition device; part of the facial image data can be facial muscles (also known as facial expressions). The facial image data corresponding to the position where the muscle is located, or may be partial facial image data that can effectively characterize the patient's expression obtained after screening the entire facial image data.

In addition, during radiotherapy, the patient is in a state of being fastened by a positioner to ensure the accuracy of radiotherapy. The positioner may include a facial mask or a body mask. That is, during radiation therapy, a mask may be attached to the patient's face. After attaching the mask, part of the patient's face may be blocked by the mask.

If the patient does not attach the mask during radiotherapy, the normal lower face image data may include: the normal face image data without the mask attached; if the patient attaches the face mask during radiotherapy, the normal lower face image data includes : Facial image data with a mask attached in a normal state, or facial image data without a mask attached in a normal state.

In addition, the facial image data may include: entire facial image data or partial facial image data. The entire facial image data or part of the facial image data is directly collected or obtained by removing the mask.

The mask removal process can specifically include: virtual calculation of the facial image data when the mask is attached to remove the mask; using light-permeable materials to make the mask, and irradiating the patient with light that can pass through the mask to collect the facial image after the mask is removed Data; or, obtain the entire facial image data, then identify the facial mask in the facial image data, and perform the mask removal process according to the recognition result.

For example, the partial facial image data obtained by direct collection is partial facial image data obtained through facial mask cuts and/or facial mask gaps, or partial facial image data obtained through a face without a facial mask attached.

For example, in this embodiment, the facial mask may be a facial mask with cuts and/or voids.

When the mask is a mask with incisions, the number of incisions on the mask can be 5, which can correspond to 5 areas of the face for judging expressions. For example, the incisions of the mask can correspond to the patient’s mouth, eyes or nose . A mask with cuts can be as shown in Figure 3B.

For example, in this embodiment, the facial mask with voids may be a facial mask with voids exposing the face after covering the face of the patient.

For example, the facial image data attached to the mask may be directly collected, and the facial image data can be filtered according to the mask incisions and/or mask gaps, so as to obtain partial facial image data through the mask incisions and/or mask gaps.

In addition, in actual use, since the patient's vomiting is the case with a high probability of occurrence, for this reason, in the embodiment of the present application, the incision of the mask preferably corresponds to the mouth, and part of the facial image data includes: the patient's mouth image data, so In the subsequent steps, the patient's mouth movement can be determined based on the patient's mouth image data, and predict whether the patient will experience vomiting in advance, so as to avoid hypoxia caused by vomiting as much as possible in advance.

Similarly, the patient’s eyes can clearly reflect the patient’s expression. For example, in some cases, the patient’s eyes will change before vomiting, such as squinting. For this reason, the incision of the mask can be further combined with If the patient’s eyes correspond, part of the facial image data also includes: the patient’s eye image data, so that in the subsequent steps the patient’s eye movement can be determined based on the patient’s eye image data, and the eye movement assistance can be used to determine more accurately The patient's expression.

Of course, the facial mask attached by the patient can also be a common facial mask, etc., which is not limited in this embodiment.

An ordinary facial mask can be a facial mask that basically covers the patient's face, for example, as shown in FIG. 3C.

It should be noted that, in order to improve the accuracy of facial image data, it is preferable to obtain facial image data based on the principle of structured light.

In addition, because part of the light cannot pass through the mask, etc., the accuracy of the facial image data obtained after the mask removal process is low. Therefore, in this embodiment, when the patient attaches the facial mask, it may be preferable to use a facial mask with gaps and/or incisions, so that partial facial image data obtained through the gaps and/or incisions of the mask can further improve the amount of facial image data obtained. accuracy. Of course, in order to save costs, the principle of light reflection can also be used to collect facial image data.

For example, a mask made of light-permeable materials can also be used, such as materials that can transmit infrared light, and light (for example, infrared light) corresponding to the mask made of light-permeable materials can be used to illuminate the patient's face to obtain Facial image data based on infrared light, since infrared light will be interfered by the patient’s blood vessels, etc., facial image data collected based on infrared light can be used as an auxiliary to correct the data collected based on the structured light principle or collected by the light reflection principle Facial image data to further improve the accuracy of the determined facial image data.

S302: Acquire current preset area image data during the radiotherapy process.

The current preset area image data in the radiotherapy process may be image data obtained by infrared imaging or a camera.

The preset area may specifically be the patient's face.

For example, in this embodiment, the preset area is the patient's face. Since the facial expression of the patient can more intuitively reflect the state of the patient, setting the preset area as the face of the patient can make the current state feature information determined in the subsequent steps correspond to the patient's facial expression, thereby making the current state feature The information can more accurately reflect the current state of the patient, so that emergency treatment is more in line with the needs of the patient.

In radiotherapy, multiple facial image data can be obtained. If the change of the multiple facial image data is greater than a preset value, one of the multiple facial image data can be used as the facial image data in the radiotherapy process. For example, one of the multiple facial image data with better quality or the one with larger difference may be used as the facial image data in the radiotherapy process.

In this embodiment, if the preset area is the patient's face, the facial image data may include: entire facial image data or partial facial image data.

The facial image data includes: entire facial image data or partial facial image data. The entire facial image data or part of the facial image data is directly collected or obtained by removing the mask.

The partial facial image data obtained by direct collection is partial facial image data obtained through a facial mask incision, or partial facial image data obtained through a face without a facial mask attached.

For example, in this embodiment, when the facial mask is a facial mask with incisions, the specific facial mask with incisions may be as described above, which will not be repeated in this embodiment.

Similarly, the patient’s eyes can clearly reflect the patient’s expression. For example, in some cases, the patient’s eyes will change before vomiting, such as squinting. For this reason, the incision of the mask can be further combined with If the patient’s eyes correspond, part of the facial image data also includes: the patient’s eye image data, so that in the subsequent steps, the patient’s eye movements can be determined based on the patient’s eye image data, and the eye movements can be assisted to determine more accurately The patient's expression.

Of course, the facial mask can also be a normal facial mask, a facial mask with voids, etc., which is not limited in this embodiment.

S303: Analyze according to the current preset area image data and the preset area image data in a normal state, and determine the current state characteristic information of the patient.

In this embodiment, the current preset area image data can be compared with the preset area image data in the normal state to analyze the difference between the current preset area image data and the preset area image data in the normal state. Determine the patient's current state characteristic information.

S304. Generate a corresponding control instruction according to the current state characteristic information, and control the radiotherapy system to perform emergency treatment according to the control instruction.

The current state characteristic information can be divided into emergency state and non-emergency state. For example, if the patient is currently relatively calm, the current state characteristic information is an emergency state; if the patient is currently panicked or vomiting, the emergency state is an emergency state.

For example, step S304 includes: if the current state characteristic information is a non-emergency state, a control instruction may not be generated, or a control instruction for maintaining the radiation treatment of the radiotherapy system may be generated so as to maintain the radiotherapy system Irradiation therapy. This embodiment does not limit this.

For example, step S304 includes: if the current state characteristic information is an emergency state, generating a first control instruction, and suspending the radiation treatment of the radiotherapy system according to the first control instruction.

If the patient is in a fastened state by the positioner, step S304 may include: if the current state characteristic information is an emergency state, generating a second control instruction, and release the fastened state of the positioner according to the second control instruction.

For example, the positioner may include a facial mask or a body mask. Correspondingly, releasing the fixed state of the retainer can be opening the facial mask or body mask.

For example, in this embodiment, before step S304, the method may further include: analyzing the acquired current motion data and preset motion data to determine the current state characteristic information of the patient.

In this embodiment, the motion data can be used to determine the patient's motion, such as waving a hand, blinking, and making gestures.

The preset action data can be determined according to the agreement between the patient and the doctor. For example, a fixed gesture or action corresponding to the emergency state can be pre-appointed. Actions can be blinking, continuous left and right eye movements, etc., and the preset action data can be determined accordingly.

Collect current motion data during radiotherapy, and if the current motion data and preset motion data are analyzed, it can be determined that the user has performed the agreed action, and the patient's current state characteristic information can be determined to be an emergency state. As a result, the accuracy of the determined current state characteristic information can be improved.

In addition, because the patient may forget the pre-appointed action when in an emergency state, in this embodiment, the above-mentioned "based on the current preset area image data and the preset area image data in the normal state can be analyzed, Determining the current state characteristic information of the patient" and “determining the current state characteristic information of the patient by analyzing the acquired current movement data and preset movement data” are used at the same time to determine the current state characteristic information. Further ensure the accuracy of the determined current state characteristic information.

In addition, by way of example, in this embodiment, before step S304, the method may further include: determining the current state characteristic information of the patient according to the information communication data with the patient. As a result, the accuracy of the determined current state characteristic information can be further improved.

The information communication data with the patient may specifically include: voice played to the patient and feedback data of the patient.

The content of the voice played to the patient through the microphone may include "whether there is discomfort", "whether treatment is terminated", and so on. Then the patient's feedback can be obtained, and the patient's feedback can be "um", "stop treatment", etc. sent by the patient, and thus the patient's current state characteristic information can be determined.

In addition, the voice played to the patient can be automatically generated or played automatically to achieve automatic voice reminders.

In addition, the patient's feedback data can be collected by a sound collection device, and the sound collection device can be set at a preset position in the radiotherapy system, and the preset position is within a preset distance range from the patient's head. For example, the sound collection device may be set on a treatment bed, a positioner, or a radiotherapy equipment in a radiotherapy system.

In addition, the patient’s voice can also be collected through the sound collection device, and the patient’s current state characteristic information can be determined based on the collected voice. The state characteristic information is an emergency state.

In addition, any of the above-mentioned steps or implementations in this embodiment, such as "during radiotherapy, obtain the current audio data of the patient; determine the current state characteristic information according to the current audio data", etc., can also be applied In other embodiments, this application does not limit this.

4A is a schematic flow chart of an emergency control method in a radiotherapy system according to Embodiment 4 of the application. In this embodiment, the preset area includes the patient's face and the patient attaches a mask during radiotherapy as an example. illustrate. As shown in FIG. 4A, it includes the following steps S401, S402, S403, and S404:

S401: Acquire facial image data of a patient with a mask attached in a normal state.

In an implementation manner, step S401 may include collecting facial image data of a patient with a mask attached in a normal state, for example, as shown in FIG. 4B.

The facial mask attached by the patient may include a facial mask having openings.

The mask attached under normal conditions is the same as the mask attached by the patient during radiotherapy.

In another implementation manner, step S401 may further include: performing a virtual calculation according to the facial image data of the patient who is not attached with the facial mask in a normal state to determine the facial image data of the patient who is attached with the facial mask. In this way, the modeling file of the mask can be determined, and there is no need to make an attached mask in advance, which improves the efficiency of radiotherapy.

According to the facial image data of the patient without the mask in the normal state, the virtual calculation can be based on the modeling file of the mask and the facial image data without the mask attached to the simulation to determine the face of the patient with the mask attached Image data.

The facial image data corresponding to the facial image data before and after the virtual calculation does not change. Therefore, after the virtual calculation, the facial image data of the patient with the mask attached to the facial mask corresponding to the facial expression can be directly determined. And only the facial image data of patients who are not attached to the mask under the normal state before radiotherapy can be collected, which reduces the difficulty of collecting facial image data. Of course, the above is only an example and not a limitation of this application.

S402. Acquire current facial image data during the radiotherapy process.

In this step, the current facial image data during the radiotherapy process can be acquired. In addition, the current facial image data may be image data obtained by infrared imaging or a camera.

Compared with the unprocessed facial image data, by comparing the facial feature data, the determined current state feature information can be made more accurate.

The facial feature data of the patient with the mask attached in the normal state may specifically include the facial feature data corresponding to the patient with the mask attached in the normal state when they are calm, uncomfortable, and fearful.

For example, the facial feature data of a patient with a mask attached in a normal state can be determined in advance. For example, after step S401, the face of the patient with a mask attached can be determined based on the comparison of the same expression of the patient with the mask attached to the mask without the mask in the normal state. Characteristic data. Alternatively, during radiotherapy, facial image data can be obtained. If the change in the facial image data is less than a preset threshold, the facial image data is used as the facial image data attached to the mask in the normal state, and the facial feature data is determined accordingly .

Of course, the above is only an example, as long as the facial feature data of the patient with the mask attached in the normal state is determined before step S403, which is not limited in this embodiment.

In addition, the comparison of the mask with the same expression and the mask without the mask may specifically be a comparison of the facial image data with the mask attached and the facial image data without the mask under the same expression.

In an implementation manner, in a normal state, the facial image data corresponding to the same expression, with and without the mask attached, can be collected, and comparison is performed after the collection to determine the facial feature data of the patient with the mask attached.

In another implementation, the facial image data without the mask attached can be collected in a normal state, and virtual calculations can be performed based on the facial image data without the mask attached to determine the facial image data of the patient with the mask attached, and then compare the unattached facial image data The facial image data of the facial mask and the facial image data of the patient with the facial mask obtained by virtual calculation are determined to determine the facial feature data of the patient with the facial mask. The specific virtual calculation process and the related content in the above step S401 will not be repeated here.

By comparing the attached and unattached masks under the same expression, the recognition position corresponding to the expression when the mask is attached can be determined, that is, the expression can be more accurately recognized through the image data corresponding to the recognition position. Then, according to the recognition position, the facial feature data of the patient with the mask attached in the normal state can be determined, that is, the facial feature data corresponding to the patient when the patient is calm, uncomfortable, and fearful, so as to improve the accuracy of the current state feature information determined in the subsequent steps.

Of course, the above is only an example and is not a limitation of this application. Other methods of determining facial feature data of a patient with a mask attached in a normal state are also within the protection scope of this application.

S404: Generate a corresponding control instruction according to the current state characteristic information, and control the radiotherapy system to perform emergency treatment according to the control instruction.

For the specific implementation of this step, reference may be made to the foregoing step S304, which will not be repeated here.

When the patient attaches the mask with voids and/or incisions, the mask voids and/or mask incisions will not cover the patient's face. Therefore, compared with the facial image data of patients who directly use the mask attached under normal conditions, the mask voids and/or Or the image data of the mask incision can improve the accuracy of the determined current state characteristic information.

For example, the facial image data of the patient with the mask attached in the normal state can be collected, and then the image data of the mask gap and/or the mask incision can be extracted from it, for example, as shown in FIG. 5B.

Alternatively, it is possible to collect facial image data without the mask attached in a normal state, and then perform virtual calculations to determine the facial image data of the patient with the mask attached, and then extract it to obtain the image data of the mask gap and/or the mask incision.

It should be understood that the above is only an example and not a limitation of the present application. Other schemes that can determine the image data of the mask gap and/or the mask cut are also within the protection scope of the present application.

After determining the current facial image data, according to the modeling file of the facial mask, the part of the facial image data corresponding to the facial mask can be removed to obtain the image data of the current facial mask gap and/or the current facial mask cut.

For example, as shown in FIG. 5B, after determining the image data of the current mask gap and/or the current mask cut, it can be analyzed with the image data of the mask gap and/or mask cut in the normal state to determine the current state characteristic information.

For example, the image data of the current mask gap and the image data of the mask gap in the normal state can be analyzed to determine the current state characteristic information; or, the image data of the current mask incision can be compared with the image data of the mask incision in the normal state. Perform analysis to determine the current state characteristic information; alternatively, you can also analyze the image data of the current mask gap and the image data of the mask cut in the normal state to determine the current state characteristic information; alternatively, you can also use the current mask cut image data Analyze the image data of the mask gap in the normal state to determine the characteristic information of the current state. This embodiment does not limit this.

S504: Generate a corresponding control instruction according to the current state characteristic information, and control the radiotherapy system to perform emergency treatment according to the control instruction.

So far, specific embodiments of the subject matter have been described. Other embodiments are within the scope of the appended claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve desired results. In addition, the processes depicted in the drawings do not necessarily require the specific order or sequential order shown in order to achieve the desired result. In certain embodiments, multitasking and parallel processing may be advantageous.

In the 1990s, the improvement of a technology can be clearly distinguished between hardware improvements (for example, improvements in circuit structures such as diodes, transistors, switches, etc.) or software improvements (improvements in method flow). However, with the development of technology, the improvement of many methods and processes of today can be regarded as a direct improvement of the hardware circuit structure. Designers almost always get the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be realized by the hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (for example, a Field Programmable Gate Array (Field Programmable Gate Array, FPGA)) is such an integrated circuit whose logic function is determined by the user's programming of the device. It is programmed by the designer to "integrate" a digital system on a piece of PLD, without requiring chip manufacturers to design and manufacture dedicated integrated circuit chips. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly realized by using "logic compiler" software, which is similar to the software compiler used in program development and writing, but before compilation The original code must also be written in a specific programming language, which is called Hardware Description Language (HDL), and there is not only one type of HDL, but many types, such as ABEL (Advanced Boolean Expression Language) , AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description), etc., currently most commonly used It is VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. It should also be clear to those skilled in the art that only a little logic programming of the method flow in the above-mentioned hardware description languages and programming into an integrated circuit can easily obtain the hardware circuit that implements the logic method flow.

The controller can be implemented in any suitable manner. For example, the controller can take the form of, for example, a microprocessor or a processor and a computer-readable medium storing computer-readable program codes (such as software or firmware) executable by the (micro)processor. , Logic gates, switches, application specific integrated circuits (ASICs), programmable logic controllers and embedded microcontrollers. Examples of controllers include but are not limited to the following microcontrollers: ARC625D, Atmel AT91SAM, Microchip PIC18F26K20 and Silicon Labs C8051F320, the memory controller can also be implemented as part of the memory control logic. Those skilled in the art also know that, in addition to implementing the controller in a purely computer-readable program code manner, it is entirely possible to program the method steps to make the controller use logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded logic. The same function can be realized in the form of a microcontroller or the like. Therefore, such a controller can be regarded as a hardware component, and the devices included in it for realizing various functions can also be regarded as a structure within the hardware component. Or even, the device for realizing various functions can be regarded as both a software module for realizing the method and a structure within a hardware component.
