Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a medical system related to a communication connection monitoring method according to 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 may be connected in communication.
In an embodiment of the present application, the medical system 100 may further include: and a radiotherapy device 103 connected with the lower computer 102. Wherein the radiotherapy apparatus 103 may comprise: gamma knife or executive accelerator.
For example, the upper computer 101 may be a computer that directly transmits a control command, and for example, the upper computer 101 may be a desktop computer or a notebook computer. The lower computer 102 generally refers to a computer that directly controls the operation state of the radiotherapy apparatus, and for example, the lower computer 102 may be a motion control component of the radiotherapy apparatus. In this manner, the lower computer 102 may control the movement of the couch and/or the rotating gantry in the radiotherapy apparatus.
The upper computer 101 is provided with upper computer software, and the lower computer 102 is provided with lower computer software.

In the present application, the upper computer 101 may be communicatively connected to the lower computer 102 through middleware. The middleware refers to software that connects two independent applications (i.e., upper computer software and lower computer software).
Referring to fig. 2, fig. 2 is a flowchart of a method for monitoring communication connection according to an embodiment of the present application. The monitoring method of the communication connection is applied to the upper computer 101 in the treatment system 100 shown in fig. 1. The monitoring method of the communication connection comprises the following steps:
Step 201, after the upper computer is in communication connection with the lower computer, the heartbeat numbers are written into the lower computer periodically, and the heartbeat numbers written into the lower computer each time are different.
Step 202, if the upper computer fails to write the number into the lower computer at least once, determining that the communication connection between the upper computer and the lower computer is abnormal.

In summary, according to the method for monitoring communication connection provided by the embodiment of the application, the upper computer can periodically write the heartbeat number into the lower computer, and after the upper computer fails to write the heartbeat number into the lower computer at least once, the upper computer can determine that the communication connection between the upper computer and the lower computer is abnormal. Because the heartbeat numbers written into the lower computer by the upper computer are different every time, the lower computer can periodically read the heartbeat numbers written into the upper computer, and after the same heartbeat numbers are read at least twice, the lower computer can determine that the communication connection between the lower computer and the upper computer is abnormal. Therefore, the monitoring method of the communication connection can ensure that when the medical system works, the upper computer can monitor whether the communication connection between the upper computer and the lower computer is normal or not in real time, and the lower computer can monitor whether the communication connection between the lower computer and the upper computer is normal or not in real time, so that the safety of diagnosing or treating a patient by adopting the medical system is higher.
Referring to fig. 3, fig. 3 is a flowchart of another method for monitoring communication connection according to an embodiment of the present application. The monitoring method of the communication connection is applied to the lower computer 102 in the treatment system 100 shown in fig. 1. The monitoring method of the communication connection comprises the following steps:

The heartbeat numbers are written in periodically by the upper computer, and the heartbeat numbers written in by the upper computer to the lower computer are different each time.
Step 302, if the heartbeat numbers read by the lower computer at least twice are the same, determining that the communication connection between the upper computer and the lower computer is abnormal.
In summary, according to the method for monitoring communication connection provided by the embodiment of the application, the upper computer can periodically write the heartbeat number into the lower computer, and after the upper computer fails to write the heartbeat number into the lower computer at least once, the upper computer can determine that the communication connection between the upper computer and the lower computer is abnormal. Because the heartbeat numbers written into the lower computer by the upper computer are different every time, the lower computer can periodically read the heartbeat numbers written into the upper computer, and after the same heartbeat numbers are read at least twice, the lower computer can determine that the communication connection between the lower computer and the upper computer is abnormal. Therefore, the monitoring method of the communication connection can ensure that when the medical system works, the upper computer can monitor whether the communication connection between the upper computer and the lower computer is normal or not in real time, and the lower computer can monitor whether the communication connection between the lower computer and the upper computer is normal or not in real time, so that the safety of diagnosing or treating a patient by adopting the medical system is higher.
Referring to fig. 4, fig. 4 is a flowchart of a method for monitoring a communication connection according to another 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 comprises the following steps:
step 401, after the upper computer and the lower computer are in communication connection, the upper computer periodically writes heartbeat numbers into the lower computer, and each time the heartbeat numbers written into the lower computer are different.
For example, the heartbeat numbers written into the lower computer by the upper computer periodically are arranged in an arithmetic series or an arithmetic series. For example, assuming that the heartbeat numbers written into the lower computer by the upper computer periodically form an arithmetic progression, the heartbeat numbers written into the lower computer by the upper computer periodically may be in turn: n, n+1, n+2, etc. Wherein n may be an integer greater than or equal to 0.
Optionally, the writing of the heartbeat number to the lower computer by the upper computer periodically includes: and the upper computer periodically writes heartbeat numbers into a controller in the lower computer. For example, the controller may be a Central Processing Unit (CPU), a Microprocessor (MPU), a Field Programmable Gate Array (FPGA), or the like.
For example, the controller has a memory address for storing the heartbeat number, and the host computer can write the heartbeat number into the memory address.
It should be noted that, only one heartbeat number is stored in the storage address, when the upper computer writes the heartbeat number into the storage address of the lower computer every time, the storage address erases the heartbeat number written by the upper computer last time, and stores the heartbeat number to be written by the upper computer this time.
In the embodiment of the present application, the method for monitoring communication connection may further include the steps of: after the upper computer writes the heartbeat number into the lower computer each time, the upper computer receives the feedback identification sent by the lower computer. The feedback mark is used for indicating whether the heartbeat number written by the upper computer to the lower computer is successful or not.
By way of example, the upper computer may be communicatively coupled to the lower computer via middleware. Thus, after the upper computer writes the heartbeat number into the lower computer each time, the upper computer receiving the feedback identifier sent by the lower computer may include: and after the upper computer writes the heartbeat number into the lower computer through the middleware each time, receiving a feedback identification sent by the middleware.
The middleware is used for generating a feedback identifier after writing the heartbeat number into the lower computer each time. The feedback mark is used for indicating whether the upper computer writes the heartbeat number into the lower computer successfully or not.
For example, the feedback identification may include: a write success identification or a write failure identification. When the lower computer is abnormal and cannot work, the middleware cannot write the heartbeat number into the lower computer, and at the moment, the middleware can generate a writing failure identifier and send the writing failure identifier to the upper computer so as to inform the upper computer that the writing of the heartbeat number into the lower computer fails; when the lower computer can normally work, the middleware can write the heartbeat number into the lower computer, at the moment, the middleware can generate a successful writing identification and send the successful writing identification to the upper computer so as to inform the upper computer that the heartbeat number is successfully written into the lower computer.
It should be noted that, the phenomenon that the lower computer is abnormal and cannot work generally means that: the lower computer is in abnormal phenomena such as downtime or jamming, at the moment, the upper computer cannot send a control command to the lower computer, and the communication connection between the upper computer and the lower computer is abnormal.
In the embodiment of the present application, the method for monitoring communication connection may further include the following steps:
and step A, before the upper computer writes the heartbeat number into the lower computer each time, the upper computer checks whether the communication connection with the lower computer is successfully established.
For example, the upper computer may check through the middleware whether the communication connection with the lower computer is successfully established. If the upper computer checks that communication connection is established with the lower computer through the middleware, executing the step B; and C, if the upper computer detects that communication connection is not established with the lower computer through the middleware, executing the step C.
And step B, if the upper computer checks that communication connection is established with the lower computer, executing the operation of writing the heartbeat number into the lower computer.
And step C, if the upper computer is not in communication connection with the lower computer, the upper computer determines that the upper computer is not in communication connection with the lower computer, and determines that the writing of the heartbeat number to the lower computer fails.
In the embodiment of the application, before the upper computer writes the heartbeat number into the lower computer each time, the upper computer needs to determine whether communication connection between the upper computer and the lower computer exists by taking the specified function in the middleware.
For example, if the upper computer invokes the specified function from the middleware, the upper computer can determine that the upper computer and the lower computer are successfully connected to establish communication, that is, the upper computer can determine that the upper computer and the lower computer are connected to each other, and then the upper computer can execute the operation of writing the heartbeat number into the lower computer; if the upper computer does not call the appointed function from the middleware, the upper computer can determine that the upper computer does not establish communication connection with the lower computer, that is, the upper computer can determine that the upper computer does not have communication connection with the lower computer, the upper computer does not execute the operation of writing the heartbeat number into the lower computer, and the upper computer can determine that the writing of the heartbeat number into the lower computer fails, and then the upper computer needs to repeatedly execute the operation of calling the appointed function from the middleware.
Step 402, after the upper computer writes the heartbeat number into the lower computer each time, the upper computer determines whether the heartbeat number is successfully written into the lower computer.
In the embodiment of the application, after the upper computer writes the heartbeat number into the lower computer each time, the upper computer can receive the feedback identification sent by the middleware and determine whether the heartbeat number is successfully written into the lower computer based on the feedback identification.
For example, after receiving the feedback identifier sent by the middleware, if the upper computer determines that the feedback identifier is an identifier for indicating that the upper computer writes the heartbeat number to the lower computer successfully, that is, the feedback identifier is a writing success identifier, the upper computer determines that the writing of the heartbeat number to the lower computer is successful, and then the following step 403 is executed; if the upper computer determines that the feedback identifier is an identifier for indicating that the upper computer fails to write the heartbeat number to the lower computer, that is, the feedback identifier is a writing failure identifier, the upper computer determines that the writing of the heartbeat number to the lower computer fails, and the upper computer may be in abnormal communication connection with the lower computer, so as to execute the following step 404.
And step 403, if the upper computer determines that the heartbeat number written into the lower computer is successful, the upper computer determines that the communication connection between the upper computer and the lower computer is normal.
For example, if the upper computer determines that the current writing of the heartbeat number to the lower computer is successful based on the feedback identifier sent by the middleware, for example, when the upper computer receives the writing success identifier sent by the middleware, the upper computer may determine that the current writing of the heartbeat number to the lower computer is successful. And the upper computer can determine that the communication connection between the upper computer and the lower computer is normal.
And 404, if the upper computer determines that the writing of 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 a 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 the upper computer and the lower computer is abnormal.
For example, 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 writing failure identifier sent by the middleware, the upper computer may determine that writing the heartbeat number to the lower computer fails. And the upper computer can determine that the communication connection between the upper computer and the lower computer is abnormal.
In a second possible implementation manner, the upper computer needs to determine that writing of the heartbeat number to the lower computer fails a plurality of times continuously, and the upper computer can determine that the communication connection between the upper computer and the lower computer is abnormal.
For example, according to the above embodiment, the upper computer determines that the writing of the heartbeat number to the lower computer fails in the following two cases:
in the first case, before the upper computer writes the heartbeat number into the lower computer every time, when the upper computer determines that the communication connection between the upper computer and the lower computer does not exist in a mode of calling the specified function in the middleware, the upper computer can determine that the writing of the heartbeat number into the lower computer fails.
In the second case, after the upper computer writes the heartbeat number into the lower computer each time, if the upper computer determines that the heartbeat number is failed to be written into the lower computer based on the feedback identifier sent by the middleware, for example, when the upper computer receives the writing failure identifier sent by the middleware, the upper computer can determine that the heartbeat number is failed to be written into the lower computer this time.
And combining the two cases, after determining that the writing of the heartbeat number to the lower computer fails, the upper computer can record the failure once. Therefore, the upper computer can determine whether the heartbeat number written into the lower computer by the upper computer is failed continuously for a plurality of times through the recorded continuous failure times, and determine that the passing connection between the upper computer and the lower computer is abnormal after the upper computer continuously determines that the heartbeat number written into the lower computer is failed for a plurality of times.
For example, if the upper computer determines to write the heartbeat number to the lower computer 3 times in succession, the upper computer may 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 application, after the upper computer determines that the communication connection between the upper computer and the lower computer is abnormal, the upper computer can output prompt information.
For example, the prompt information may be a text message, and the upper computer may display the output prompt information on a display interface of the upper computer, so as to prompt the staff that the communication connection between the upper computer and the lower computer is abnormal.
Step 406, the lower computer periodically reads the heartbeat numbers written by the upper computer.
In the embodiment of the application, after the upper computer periodically writes the heartbeat number into the lower computer, the lower computer can periodically read the heartbeat number stored in the lower computer.
Optionally, because 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 numbers written by the upper computer from the controller of the lower computer.
In the application, the period duration of the heartbeat number written into the lower computer by the upper computer is smaller than or equal to the period duration of the heartbeat number read by the lower computer. That is, if the upper computer takes the first duration as the period, the heartbeat number is written into the lower computer periodically, and the lower computer takes the second duration as the period, and the heartbeat number is stored by the periodic reader, the first duration is smaller than or equal to the second duration. For example, the first duration may be 200 milliseconds and the second duration may be 2 seconds.
When the period duration of the heartbeat number written into the lower computer by the upper computer is smaller than or equal to the period duration of the heartbeat number read by the lower computer, the subsequent lower computer can determine whether the communication connection between the lower computer and the upper computer is normal or not through the read heartbeat number.
Step 407, after the lower computer reads the heartbeat number each time, the lower computer compares whether the heartbeat number read currently is the same as the heartbeat number read last time.
For example, if the lower computer determines that the current read heartbeat number is not the same as the last read heartbeat number, then step 408 is performed; if the lower computer determines that the current 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 current read heartbeat number is different from the last read heartbeat number, the lower computer determines that the communication connection between the lower computer and the upper computer is normal.
In the embodiment of the application, the period duration of the upper computer writing the heartbeat number into the lower computer is smaller than or equal to the period 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 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 are different each time. Therefore, if the lower computer determines that the current read heartbeat number is different from the last read heartbeat number, the lower computer can determine that the communication connection between the lower computer and the upper computer is normal.
And 409, if the heartbeat numbers read by the lower computer at least twice continuously are the same, determining that the communication connection between the lower computer and the upper computer is abnormal by the lower computer.
In the first exemplary implementation manner, as long as the heartbeat numbers read by the lower computer are the same in two consecutive times, 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 current read heartbeat number is the same as the last read heartbeat number, the lower computer determines that the communication connection between the lower computer and the upper computer is abnormal.
In a second exemplary implementation, the lower computer needs to determine that writing the heartbeat number to the lower computer fails multiple times (three times or more) in succession, and the lower computer can determine that the communication connection between the lower computer and the upper computer is abnormal.
If the lower computer determines that the current read heartbeat number is the same as the last read heartbeat number, at least one heartbeat number is continuously read, and when the heartbeat number read each time is the same as the last read heartbeat number, the lower computer determines that the communication connection between the lower computer and the upper computer is abnormal.
In the embodiment of the application, when the communication connection between the upper computer and the lower computer is abnormal, the upper computer can not write the new heartbeat number into the lower computer, and the lower computer always stores the heartbeat number which is written into the upper computer for the last time when the communication connection between the upper computer and 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 are the same each time. Therefore, if the heartbeat numbers read by the lower computer for a plurality of 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 is the same for 3 consecutive times, 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 send out an alarm signal and controls the radiotherapy equipment to stop working.
