Detailed ways

In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

Please refer to FIG. 1. FIG. 1 is a schematic structural diagram of a medical system involved in a method for monitoring a communication connection provided by an embodiment of the present application. The medical system 100 may include: an upper computer 101 and a lower computer 102 . The upper computer 101 and the lower computer 102 can be communicatively connected.

In this embodiment of the present application, the medical system 100 may further include: a radiotherapy device 103 connected to the lower computer 102 . Wherein, the radiotherapy equipment 103 may include: a gamma knife or an executive accelerator.

For example, the host computer 101 may be a computer that directly sends control commands. For example, the host computer 101 may be a desktop computer or a notebook computer. The lower computer 102 usually refers to a computer that directly controls the operation state of the radiotherapy equipment. For example, the lower computer 102 may be a motion control component of the radiotherapy equipment. In this way, the lower computer 102 can control the movement of the treatment couch and/or the rotating gantry in the radiotherapy equipment.

The upper computer 101 is installed with upper computer software, and the lower computer 102 is installed with lower computer software. The upper computer 101 can send control commands to the upper computer 102 through the upper computer software. After receiving the control command, the lower computer 102 can control the operation state of the radiotherapy equipment 103 through the software of the lower computer, so that the radiotherapy equipment 103 can diagnose or treat the patient.

In the present application, the upper computer 101 may be connected to the lower computer 102 for communication through middleware. The middleware refers to software that connects two independent application programs (that is, the upper computer software and the lower computer software).

Please refer to FIG. 2 , which is a flowchart of a method for monitoring a communication connection provided by an embodiment of the present application. The communication connection monitoring method is applied to the host computer 101 in the treatment system 100 shown in FIG. 1 . The monitoring method of the communication connection includes:

Step 201: After the upper computer is connected to the lower computer for communication, periodically write the heartbeat number to the lower computer, and the heartbeat number written to the lower computer is different each time.

Step 202: If the upper computer fails to write numbers to the lower computer at least once, it is determined that the communication connection between the upper computer and the lower computer is abnormal.

The heartbeat number is used for periodic reading by the lower computer, so that the lower computer determines that the communication connection between the lower computer and the upper computer is abnormal after reading the same heartbeat number several times in a row.

To sum up, in the communication connection monitoring method provided by the embodiment of the present application, the host computer can periodically write the heartbeat number to the host computer, and after the host computer fails to write the heartbeat number to the host computer at least once, the host computer fails to write the heartbeat number to the host computer at least once. It can be determined that the communication connection between it and the lower computer is abnormal. Since the heartbeat number written by the host computer to the host computer is different each time, the host computer can periodically read the heartbeat number written by the host computer, and after the connection reads the same heartbeat number twice at least, the host computer can read the heartbeat number written by the host computer periodically. The computer can determine that the communication connection between it and the upper computer is abnormal. In this way, the monitoring method of the communication connection can ensure that when the medical system is working, the upper computer can monitor in real time whether the communication connection between it and the lower computer is normal, and the lower computer can also monitor in real time whether the communication connection between it and the upper computer is normal. It is normal to ensure that the medical system is used to diagnose or treat patients with high safety.

Please refer to FIG. 3 , which is a flowchart of another communication connection monitoring method provided by an embodiment of the present application. The communication connection monitoring method is applied to the lower computer 102 in the treatment system 100 shown in FIG. 1 . The monitoring method of the communication connection includes:

Step 301: After the lower computer establishes a communication connection with the upper computer, periodically read the heartbeat number written by the upper computer. The heartbeat number is periodically written by the host computer, and the heartbeat number written by the host computer to the host computer is different each time.

Step 302: If the heartbeat numbers read by the lower computer at least twice in a row are the same, it is determined that the communication connection between the upper computer and the lower computer is abnormal.

Please refer to FIG. 4 . FIG. 4 is a flowchart of another communication connection monitoring method provided by an embodiment of the present application. The monitoring method of the communication connection is applied to the treatment system 100 shown in FIG. 1 . The monitoring method of the communication connection includes:

Step 401: After the upper computer establishes a communication connection with the lower computer, the upper computer periodically writes heartbeat numbers to the lower computer, and the heartbeat numbers written to the lower computer are different each time.

For example, the heartbeat numbers periodically written by the host computer to the host computer are arranged in an arithmetic progression or an arithmetic progression. For example, assuming that the heartbeat numbers that the host computer periodically writes to the host computer are arithmetic progressions, then the heartbeat numbers that the host computer periodically writes to the host computer can be sequentially: n, n+1, n+2 Wait. Wherein, the n may be an integer greater than or equal to 0.

Optionally, the host computer periodically writes the heartbeat number to the host computer, including: the host computer periodically writes the heartbeat number to the controller in the host computer. For example, the controller may be a central processing unit (CPU), a microprocessor (MPU), a field programmable gate array (FPGA), or the like.

Exemplarily, the controller has a storage address for storing the heartbeat number, and the host computer can write the heartbeat number into the storage address.

It should be noted that only one heartbeat number is stored in this storage address. Every time the host computer writes the heartbeat number to the storage address of the host computer, the storage address will erase the heartbeat number written by the host computer last time, and Store the heartbeat number that the host computer needs to write this time.

In the embodiment of the present application, the monitoring method for the communication connection may further include the step of: after the upper computer writes the heartbeat number to the lower computer each time, the upper computer receives the feedback identifier sent by the lower computer. The feedback flag is used to indicate whether the heartbeat number written by the host computer to the host computer is successful.

For example, the upper computer may be connected to the lower computer through middleware for communication. In this way, after the host computer writes the heartbeat number to the host computer each time, the host computer receives the feedback identification sent by the host computer may include: after the host computer writes the heartbeat number to the host computer through the middleware every time, receiving the middleware sent Feedback logo.

Wherein, the middleware is used to generate a feedback identifier after each heartbeat number is written to the lower computer. The feedback flag is used to indicate whether the upper computer successfully writes the heartbeat number to the lower computer.

For example, the feedback identification may include: writing success identification or writing failure identification. When the upper computer fails to work due to an abnormality, the middleware cannot write the heartbeat number to the lower computer. At this time, the middleware can generate a write failure flag and send it to the upper computer to inform the upper computer of this time. The computer fails to write the heartbeat number; when the lower computer can work normally, the middleware can write the heartbeat number to the lower computer. At this time, the middleware can generate a write success flag and send it to the upper computer to inform the upper computer. This time, the heartbeat number is successfully written to the lower computer.

It should be noted that the phenomenon that the lower computer is abnormal and cannot work usually means: the lower computer is down or stuck and other abnormal phenomena. At this time, the upper computer cannot send control commands to the lower computer. The upper computer and the lower computer The communication connection between them is abnormal.

In the embodiment of the present application, the monitoring method for the communication connection may further include the following steps:

Step A. Before the upper computer writes the heartbeat number to the lower computer each time, the upper computer checks whether the communication connection is successfully established with the lower computer.

For example, the upper computer can check whether the communication connection with the lower computer is successfully established through the middleware. If the upper computer detects that a communication connection with the lower computer is established through the middleware, step B is performed; if the upper computer detects that the communication connection is not established with the lower computer through the middleware, step C is performed.

Step B. If the upper computer detects that a communication connection is established with the lower computer, the operation of writing the heartbeat number to the lower computer is performed.

Step C. If the upper computer does not establish a communication connection with the lower computer, the upper computer determines that there is no communication connection between it and the lower computer, and determines that writing the heartbeat number to the lower computer this time fails.

In the embodiment of the present application, each time the upper computer writes the heartbeat number to the lower computer, the upper computer needs to determine whether there is a communication connection between the upper computer and the lower computer by calling a specified function in the middleware.

For example, if the upper computer calls the specified function from the middleware, the upper computer can determine that it has successfully established a communication connection with the lower computer, that is, the upper computer can determine that there is a communication connection between it and the lower computer, After that, the upper computer will perform the operation of writing the heartbeat number to the lower computer; if the upper computer does not call the specified function from the middleware, the upper computer can determine that it has not established a communication connection with the lower computer, that is, The upper computer can determine that there is no communication connection between it and the lower computer, the upper computer will not perform the operation of writing the heartbeat number to the lower computer, and it will determine that writing the heartbeat number to the lower computer this time fails. The host computer needs to repeatedly perform the operation of calling the specified function from the middleware.

Step 402: After the upper computer writes the heartbeat number to the lower computer each time, the upper computer determines whether the writing of the heartbeat number to the lower computer this time is successful.

In the embodiment of the present application, after the upper computer writes the heartbeat number to the lower computer each time, the upper computer can receive the feedback identifier sent by the middleware, and based on the feedback identifier, determine whether the writing of the heartbeat number to the lower computer is successful.

For example, after the host computer receives the feedback mark sent by the middleware, if the host computer determines that the feedback mark is the mark used to instruct the host computer to write the heartbeat number to the host computer, that is, the feedback mark is to write. Enter the success sign, then the host computer determines that writing the heartbeat number to the host computer this time is successful, and executes the following step 403; , that is, if the feedback sign is a write failure sign, the upper computer determines that writing the heartbeat number to the lower computer this time fails, and the communication connection between the upper computer and the lower computer may be abnormal, and the following step 404 is performed.

Step 403: If the upper computer determines that the heartbeat number is successfully written to the lower computer this time, the upper computer determines that the communication connection between the upper computer and the lower computer is normal.

For example, if the host computer determines that the heartbeat number is successfully written to the host computer this time based on the feedback identifier sent by the middleware, for example, when the host computer receives the write success identifier sent by the middleware, the host computer can determine that this time. The next time the heartbeat number is written to the lower computer successfully. Then, the upper computer can determine that the communication connection between it and the lower computer is normal.

Step 404: If the upper computer determines that writing the heartbeat number to the lower computer fails at least once, the upper computer determines that the communication connection between the upper computer and the lower computer is abnormal.

In the first possible implementation manner, as long as the upper computer determines that writing the heartbeat number to the lower computer fails once, the upper computer can determine that the communication connection between it and the lower computer is abnormal.

For example, if the host computer determines based on the feedback identifier sent by the middleware that the heartbeat number has failed to be written to the host computer this time, for example, when the host computer receives the write failure identifier sent by the middleware, the host computer can determine that this time. The next time to write the heartbeat number to the lower computer failed. Then, the upper computer can determine that the communication connection between it and the lower computer is abnormal.

In the second possible implementation manner, the upper computer needs to determine the failure to write the heartbeat number to the lower computer several times in a row, and then the upper computer can determine that the communication connection between it and the lower computer is abnormal.

Exemplarily, according to the above-mentioned embodiment, it can be known that the upper computer determines that it fails to write the heartbeat number to the lower computer in the following two situations:

In the first case, before the upper computer writes the heartbeat number to the lower computer each time, when the upper computer determines that the communication connection between the upper computer and the lower computer does not exist by calling the specified function in the middleware, the The host computer can determine that writing the heartbeat number to the host computer this time fails.

In the second case, after the upper computer writes the heartbeat number to the lower computer each time, if the upper computer determines that writing the heartbeat number to the lower computer fails based on the feedback identifier sent by the middleware, for example, when the upper computer receives the message sent by the middleware. When writing the failure flag, the host computer can determine that the heartbeat number is failed to be written to the host computer this time.

Combining the above two situations, each time the upper computer determines that it fails to write the heartbeat number to the lower computer, the upper computer can record the failure once. In this way, the upper computer can determine whether the number of heartbeats written to the lower computer by the upper computer has failed several times in a row through the number of consecutive failures recorded, and after the upper computer determines that the number of heartbeats written to the lower computer has failed for many times in a row, Confirm that the traffic connection between it and the lower computer is abnormal.

For example, if the upper computer determines that the heartbeat number is written to the lower computer three times in a row, the upper computer can determine that the communication connection between the upper computer and the lower computer is abnormal.

Step 405, the upper computer outputs prompt information.

In the embodiment of the present application, after the upper computer determines that the communication connection between it and the lower computer is abnormal, the upper computer can output prompt information.

For example, the prompt information may be text message information, and the host computer may display the prompt information output by the host computer on the display interface of the host computer to prompt the staff that the communication connection between the host computer and the lower computer is abnormal.

Step 406: The lower computer periodically reads the heartbeat number written by the upper computer.

In the embodiment of the present application, after the upper computer periodically writes the heartbeat number to the lower computer, the lower computer can periodically read the stored heartbeat number.

Optionally, since the upper computer can periodically write the heartbeat number into the controller in the lower computer, the lower computer periodically reads the heartbeat number written by the upper computer, including: the lower computer periodically reads the heartbeat number from the lower computer. The controller of the lower computer reads the heartbeat number written by the upper computer.

In the present application, the cycle duration of the upper computer writing the heartbeat numbers to the lower computer is less than or equal to the cycle duration of the lower computer reading the heartbeat numbers. That is, if the upper computer periodically writes the heartbeat number to the lower computer with the first duration as the period, and the lower computer periodically reads the heartbeat number stored by the reader with the second duration as the period, then the first The duration is less than or equal to the second duration. For example, the first duration may be 200 milliseconds, and the second duration may be 2 seconds.

It should be noted that when the cycle duration of the upper computer writing the heartbeat number to the lower computer is less than or equal to the cycle duration of the lower computer reading the heartbeat number, the subsequent lower computer can use the read heartbeat number to determine its relationship with the upper computer. Whether the communication connection between them is normal.

Step 407: After the lower computer reads the heartbeat number each time, the lower computer compares whether the currently read heartbeat number is the same as the last read heartbeat number.

Example, if the lower computer determines that the currently read heartbeat number is different from the last read heartbeat number, then execute step 408; if the lower computer determines that the currently read heartbeat number is the same as the last read heartbeat number , the communication connection between the lower computer and the upper computer may be abnormal, and step 409 is executed.

Step 408: If the lower computer determines that the heartbeat number currently read is different from the heartbeat number read last time, the lower computer determines that the communication connection between it and the upper computer is normal.

In the embodiment of the present application, because the cycle duration of the upper computer writing the heartbeat number to the lower computer is less than or equal to the cycle duration of the lower computer reading the heartbeat number, and when the communication connection between the upper computer and the lower computer is normal, the upper computer The computer can normally write the heartbeat number into the lower computer every time. Therefore, when the communication connection between the upper computer and the lower computer is normal, the heartbeat numbers read by the lower computer each time are different. In this way, if the lower computer determines that the currently read heartbeat number is different from the last read heartbeat number, the lower computer can determine that the communication connection between it and the upper computer is normal.

Step 409: If the heartbeat numbers read by the lower computer at least twice in a row are the same, the lower computer determines that the communication connection between the lower computer and the upper computer is abnormal.

In the first exemplary implementation manner, as long as the heartbeat numbers read by the lower computer for two consecutive times are the same, the lower computer can determine that the communication connection between the lower computer and the upper computer is abnormal.

For example, if the lower computer determines that the currently read heartbeat number is the same as the last read heartbeat number, the lower computer determines that the communication connection between it and the upper computer is abnormal.

In the second exemplary implementation manner, the lower computer needs to determine the failure to write the heartbeat number to the lower computer several times (three or more) consecutively, so that the lower computer can determine that the communication connection between it and the upper computer is abnormal. .

For example, if the lower computer determines that the currently read heartbeat number is the same as the last read heartbeat number, it continues to read the heartbeat number at least once, when the heartbeat number read each time is the same as the last read heartbeat number. When the numbers are the same, the lower computer determines that the communication connection between it and the upper computer is abnormal.

In the embodiment of the present application, when the communication connection between the upper computer and the lower computer is abnormal, the upper computer cannot write the new heartbeat number into the lower computer, and the lower computer has always stored the information that the upper computer has stored in the lower computer. The last heartbeat number written when the communication connection with the lower computer is normal. Therefore, when the communication connection between the upper computer and the lower computer is abnormal, the heartbeat numbers read by the lower computer each time are the same. In this way, if the heartbeat numbers read by the lower computer for many times are the same, the lower computer can determine that the communication connection between the lower computer and the upper computer is abnormal.

For example, if the number of heartbeats read by the lower computer for three consecutive times is the same, the lower computer can determine that the communication connection between the lower computer and the upper computer is abnormal.

Step 410 , the lower computer controls the radiotherapy equipment to issue an alarm signal, and controls the radiotherapy equipment to stop working.

In the embodiment of the present application, after the lower computer determines that the communication connection between the lower computer and the upper computer is abnormal, the lower computer can control the radiotherapy equipment to send an alarm signal, and control the radiotherapy equipment to stop working.

For example, the radiotherapy equipment has an alarm buzzer and a control panel. After the lower computer determines that the communication connection between it and the upper computer is abnormal, the lower computer can control the alarm buzzer of the radiotherapy equipment to emit an alarm sound and control the radiotherapy. The fault alarm light on the control panel of the equipment lights up to alert the staff and the patients on the radiotherapy equipment that the communication connection between the upper computer and the lower computer is abnormal.

After the communication connection between the upper computer and the lower computer is abnormal, the lower computer controls the radiotherapy equipment to stop working, so as to avoid the problem of medical accidents caused by the uncontrolled continuous operation of the radiotherapy equipment.

In the related art, the communication connection method between the upper computer and the lower computer in the medical system is usually as follows: the upper computer periodically sends the heartbeat packet from the lower computer; every time the lower computer receives the heartbeat packet sent by the upper computer , generate a heartbeat feedback packet based on the heartbeat packet, and send it to the upper computer. In this way, after the lower computer has not received the heartbeat packet sent by the upper computer for a period of time, the lower computer can determine that the communication connection between it and the upper computer is abnormal; the upper computer has not received the heartbeat feedback sent by the upper computer for a period of time. After the package, the upper computer determines that the communication connection between it and the lower computer is abnormal. However, through this communication connection detection method, it is necessary to ensure that the lower computer generates a heartbeat feedback packet according to the received heartbeat packet in real time, which will occupy the computing resources of the lower computer and cause the lower computer to control the radiotherapy equipment. The resources are reduced, and more data needs to be transmitted between the upper computer and the lower computer, which reduces the efficiency of the communication connection between the upper computer and the lower computer.

However, in the embodiment of the present application, the upper computer periodically writes the heartbeat number to the lower computer through the middleware, and the heartbeat value written each time is different. The upper computer only needs the feedback identification sent by the middleware, and can determine whether the communication connection between it and the lower computer is normal; and the lower computer only needs to read the heartbeat number stored in it to determine whether it is connected with the upper computer. Whether the communication connection between the machines is normal. In this process, the upper computer only performs the writing operation, and the lower computer only performs the reading operation, and the lower computer does not need to generate a feedback information according to the heartbeat number to feed back to the upper computer.
