This ensures the reliability of the transmitted signal in complex electromagnetic environments and reduces the loss of control commands or video stuttering caused by wireless interference.

[0052] Optionally, 5G communication equipment includes: 5G CPE or 5G communication backpack.

[0053] Optionally, combined Figure 2 As shown, the local transmission network 60 includes a local 5G communication device 61 and a local 5G base station 62. The local 5G communication device 61 is connected to both the local 5G base station 62 and the local device 20, and is configured to transmit a second signal from the local device 20 to the local 5G base station 62, and to transmit a first signal from the local 5G base station 62 to the local device 20.

Furthermore, by adjusting network performance parameters such as bandwidth, latency, jitter, packet loss, and bit error rate, testing can be conducted under different network parameter configurations, fully covering network conditions that the surgical system may encounter at long distances and in various environments, such as external interference, network performance degradation, and network performance limitations. It also considers cross-carrier and cross-regional testing scenarios to achieve comprehensive and detailed verification and quantitative evaluation.

[0067] Combination Figure 4 As shown, based on the aforementioned test system for remote surgical systems, this disclosure provides a test method for remote surgical systems. The execution entity of this test method may be a processor, and the test method includes:

[0068] S401, the processor, based on the network performance adjustment device, adjusts the network performance parameters to determine the maximum network performance parameters that the remote surgical system can withstand.

[0069] S402, the processor configures the test network environment according to the extreme network performance parameters, and forms a communication network through the core transmission network, remote transmission network and local transmission network, so that remote end devices can connect with local end devices.

[0070] S403, the processor transmits the first signal generated by the remote terminal device to the local terminal device through the communication network, and transmits the second signal generated by the local terminal device to the remote terminal device through the communication network.

[0071] S404, the processor performs one or more of the following tests on the remote surgical system: functional testing, performance testing, and security testing, based on the transmission process and results of the first and second signals.

[0072] In this embodiment, a network performance tuning device simulates extreme conditions in a real network environment to determine the critical values ​​at which the remote surgical system can function normally. This identifies the limiting network performance parameters, reducing surgical risks caused by network degradation in actual deployments and ensuring system robustness. The testing system can fully reproduce the entire link environment from the doctor's console to the patient's surgical platform, making the test results more valuable for practical reference.

[0073] Optionally, the limiting network performance parameters that the remote surgical system can withstand are determined, including: measuring the original performance parameters of the remote surgical system without adding damage; gradually increasing the additional damage performance parameters added to the remote surgical system until the test system can establish a connection normally; and determining the limiting network performance parameters based on the original performance parameters and the additional damage performance parameters.

[0074] In this embodiment, by measuring the original performance parameters under no-damage conditions, the interference of device performance fluctuations on the test can be eliminated. Gradually increasing the additional performance parameters that cause damage to the remote surgical system, such as bandwidth, latency, jitter, packet loss, bit error rate, or one or more other network performance parameters, can simulate complex scenarios of multiple concurrent damages in a real network, accurately quantifying the system's ability to resist network degradation. Finally, the original performance parameters and the additional performance parameters are added together to determine the limiting network performance parameters.

[0075] In one specific embodiment, the original performance parameters without additional network impairment are monitored using a network monitoring device: bandwidth 0, latency 10 ms, jitter 5 ms, packet loss rate 0, and bit error rate 0. Then, additional impairment is added to the network performance using a network impairment instrument. The additional performance parameters with impairment, where the remote surgical system can establish a normal connection, are: bandwidth 100M, latency 90 ms, jitter 15 ms, packet loss rate 0.1%, and bit error rate 10%. -5 Finally, the original performance parameters are added to the additional impairment performance parameters to obtain the limiting network performance parameters: bandwidth 100 Mbps, latency 100 ms, jitter 20 ms, packet loss rate 0.1%, and bit error rate 10%. -5 This extreme network performance parameter represents the worst-case network condition for the remote surgical system while meeting the specified network configuration requirements. The remote surgical system is then tested under this network condition.

[0076] Optionally, the limit network performance parameters that the remote surgical system can withstand are determined, including: obtaining preset performance parameters provided by the equipment manufacturer; measuring the original performance parameters of the remote surgical system without adding damage; and determining the limit network performance parameters based on the preset performance parameters and the original performance parameters.

[0077] In this embodiment, the ultimate network performance parameters can be determined by removing the original performance parameters from the preset performance parameters provided by the device manufacturer. This reduces the clinical risks caused by relying solely on manufacturer data and supports dynamic adjustment of the ultimate network performance parameters based on the original performance, thereby obtaining more scientific and flexible ultimate network performance parameters.

[0097] The S502 processor configures the test network environment based on abnormal network performance parameters, and forms a communication network through the core transmission network, remote transmission network and local transmission network to connect remote end devices with local end devices.

[0098] S503, the processor transmits the first signal generated by the remote terminal device to the local terminal device through the communication network, and transmits the second signal generated by the local terminal device to the remote terminal device through the communication network.

[0099] The S504 processor performs anomaly environment testing on the remote surgical system based on the transmission process and results of the first and second signals.

[0100] In this embodiment, abnormal environment testing can prevent medical accidents caused by extreme network failures. For example, does the robotic arm immediately lock when the network is interrupted? Are unsent commands automatically cleared when an abnormal connection is lost? Is a "network unavailable" message displayed in real time? This allows for clear awareness of warning signs before system failure, exposes equipment design flaws, and drives product iteration.
