[0031] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0032] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0033] Example 1

[0034] like Figure 1As shown, the present invention provides a remote control system for a medical device end, the system includes a remote control end and a medical device end connected to the remote control end through a network; the remote control end includes: an acquisition module, used to acquire remote control instruction sending parameter information, the sending parameter information includes network delay information and the health of an execution device, the network delay information includes multiple network delay evaluation indicators, and the execution device is a device on the medical device end for executing the remote control instruction; a calculation module, used to calculate a first delay based on the network delay information and the health; a sending module, used to refuse to send the remote control instruction to the medical device end when the first delay is greater than a first set value; and send the remote control instruction to the medical device end when the first delay is less than or equal to the first set value.

[0035] In an embodiment of the present invention, the healthiness is determined based on the usage time, fault response time, fault frequency and fault level of the execution device, wherein determining the healthiness based on the usage time, fault response time, fault frequency and fault level includes: calculating a first lifespan based on the usage time; calculating a lifespan penalty value based on the fault impact time, fault frequency and fault level; calculating an actual lifespan based on the first lifespan and the lifespan penalty value, and calculating the healthiness based on the actual lifespan.

[0036] Specifically, the formula for calculating the actual lifespan is:

[0037] Lactual=Dti=1∑n(Fi×(Tri-Tfi)×ΔTi1)

[0038] Among them, Lactual represents the actual life of the execution equipment, which is the remaining effective life of the equipment calculated after considering factors such as equipment usage time and failures. D represents the design life of the equipment. This is the total length of time the equipment is expected to work properly under ideal conditions. T represents the time the equipment has been in use. This is the time that has passed since the equipment was put into use. N represents the total number of times the equipment has failed. This is the number of times the equipment has failed during its use. Fi represents the level of the i-th failure. This is a numerical value that indicates the severity of the failure, and the higher the value, the more serious the failure. Tfi represents the time when the i-th failure occurred. This is the time point when the i-th failure of the equipment occurred. Tri represents the resolution time of the i-th failure. This is the time point when the i-th failure of the equipment was repaired or resolved. ΔTi represents the time interval between the i-th failure and the previous failure. For the first failure, this time interval can be the time from the start of use of the equipment to the occurrence of the first failure. For subsequent failures, it is the time from the resolution of the last failure to the occurrence of this failure.

[0039] The embodiment of the present invention takes into account the design life of the equipment, the time in use, the severity of each failure, the time of occurrence and resolution, and the time interval between failures, so as to provide a more accurate assessment of the actual life of the equipment.

[0040] In one embodiment, the health degree may be calculated based on the actual life span and the life constant coefficient. In order to further improve the calculation accuracy of the health degree, the difference between the last maintenance time and the current time may be added, the maintenance time coefficient may be determined based on the difference, and the health degree may be calculated based on the life constant coefficient and the maintenance time coefficient.

[0041] In an embodiment of the present invention, calculating the first delay based on the network delay information and the health includes: inputting the network delay information into a network delay evaluation model to obtain the network delay; determining the execution delay from a delay table based on the health, wherein the delay table is used to represent the association between the health and the execution delay of the execution device.

[0042] The network delay information includes multiple network delay evaluation indicators, such as data packet transmission time, network congestion level, network signal quality, etc. The network delay evaluation model is a prediction model based on machine learning, such as random forest, support vector machine or neural network, which is used to predict the actual network delay based on the input network delay information.

[0043] Calculating network delay and device delay at the remote terminal instead of at the medical device end can effectively improve local computing efficiency and reduce delay at the medical device end. At the same time, some unsafe or invalid instructions can be removed in advance, reducing network transmission pressure and further improving remote control efficiency at the medical device end.

[0044] In the embodiment of the present invention, the medical device end includes: a control module, which is used to receive the remote control instruction and control the action of the medical device end according to the remote control instruction.

[0045] In an embodiment of the present invention, the control module includes: a calculation unit, used to obtain a computing power evaluation index and calculate a second delay based on the computing power evaluation index; an execution unit, used to refuse to execute the remote control instruction when the second delay is greater than a second set value; and control the action of the medical device end when the second delay is less than or equal to the second set value.

[0046] In the embodiment of the present invention, the second set value changes dynamically according to the time difference between the first set value and the corrected first delay, and the first delay is corrected according to the actual network delay.

[0047] Each remote control instruction corresponds to a delay, which can be divided into network delay, execution device delay and local computing power delay (second delay). Since the remote terminal cannot obtain local computing power in real time, the second delay is calculated on the medical device side to further improve the security and effectiveness of the remote control instructions.

[0048] In summary, the present invention provides a remote control system for medical equipment, which ensures the safety and effectiveness of remote control by comprehensively considering network delay and equipment health. The system includes a remote control terminal and a medical equipment terminal. After the remote control terminal obtains the sending parameter information, it calculates the first delay and decides whether to send the instruction based on the comparison result between the delay and the set value. After receiving the instruction, the medical equipment terminal calculates the second delay and decides whether to execute the instruction based on the comparison result between the delay and another set value. The present invention can improve the stability and safety of remote control and is applicable to various network environments and equipment conditions.

[0052] Step 2, calculating a first delay according to the network delay information and the health level;

[0053] Step 3: When the first delay is greater than a first set value, refuse to send the remote control instruction to the medical device end; when the first delay is less than or equal to the first set value, send the remote control instruction to the medical device end.
