[0054] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0055] Hospitals are usually deployed with medical communication systems for transmitting data of one side medical device to another side medical device. One specific structure of the medical communication system is shown in Figure 1 A portable monitoring device communicates with a remote monitoring center through a wireless communication device. One portable monitoring device can communicate with one or more wireless communication devices, and one wireless communication device can communicate with one or more portable monitoring devices. It should be noted that, Figure 1 The medical communication system shown in can also be called a telemetry system.

[0056] In the medical communication system, wireless medical devices and wireless communication devices use wireless communication resources for communication, such as telemetry dedicated frequency bands of 608-614 MHz, 1395-1400 MHz, 1427-1432 MHz, or ISM (Industrial Scientific Medical) frequency bands of 433 MHz, 2.4 GHz, 5.8 GHz.

[0057] It should be noted that in actual applications, when deploying a communication network, multiple different medical communication systems can be deployed in the same space, and different medical communication systems use different communication frequency bands, which can be completely non-overlapping or partially non-overlapping. For example, Figure 2A The 600 MHz spectrum distribution diagram shown in uses 36 channels of communication frequency band for UHF (Ultra High Frequency) system, and 37 channels of communication frequency band for RAS (Radio Astronomy Service) system or WMTS (Wireless Medical Telemetry Services) system. The communication frequency bands of the two channels are completely non-overlapping and adjacent, so the communication signals of the two medical communication systems will interfere with each other. For example, Figure 2B As shown in, the communication signals of the WMTS system can be interfered by the communication signals of the UHF system, so that an interference noise is superimposed in the communication signals of the WMTS system. Noise interference can affect communication quality, leading to a decrease in communication rate or even communication interruption, thereby affecting normal monitoring or treatment and other medical operations.

[0058] To solve the communication interference of different medical communication systems, the network layout can be changed, such as increasing the distance between wireless communication devices of different medical communication systems, but this requires overall planning and changes the deployment position of the wireless communication device, which has high engineering cost and takes a long time and is low in efficiency.

[0059] The present application provides a communication channel bandwidth setting method, which is applied to a wireless communication device, such asFigure 1 As shown, the wireless communication device is wirelessly connected with at least one wireless medical device, such as a portable monitoring device. See Figure 3 An embodiment of the method for setting the bandwidth of the communication channel is shown, which specifically includes S301-S303.

[0060] S301: When it is determined that the communication signal between the wireless communication device and the wireless medical device is interfered by the interference signal, the bandwidth of the communication signal is obtained and the bandwidth of the interference signal is determined.

[0061] The wireless communication device and the wireless medical device belong to the same medical communication system, which is referred to as the current medical communication system for distinguishing from other medical communication systems. The wireless communication device and the wireless medical device communicate with each other using the wireless communication signal, which can be interfered by the communication signal of other medical communication systems. The communication signal and the interference signal at least partially do not overlap in the communication frequency band, i.e., the communication frequency bands of the communication signal and the interference signal completely or partially do not overlap.

[0062] The wireless communication device detects whether the communication signal between the wireless communication device and the wireless medical device is interfered by the interference signal. The following detection methods can be used in combination.

[0063] One detection method can be to detect whether the interference power of the interference signal received by the wireless communication device reaches a preset interference power threshold.

[0064] Specifically, the wireless communication device performs frequency domain analysis on the received digital signal, which contains the communication signal of the medical communication system in which the wireless communication device is located and can also contain the interference signal of other medical communication signals. The frequency domain analysis can determine whether there is an interference signal. If there is an interference signal, the power of the interference signal is calculated, which is referred to as the interference power.

[0065] Since the interference of the current medical communication system can come from multiple aspects, for example, there can be interference between the wireless communication devices in the current medical communication system, in order to accurately determine the interference caused by other medical communication systems, the interference power threshold is set in advance according to the interference intensity that the other medical communication systems can cause to the wireless communication device. The calculated interference power is compared with the interference power threshold. If the interference power is greater than or equal to the interference power threshold, it is determined that the communication signal between the wireless communication device and the wireless medical device is interfered. It should be noted that the interference power threshold can be set to different values according to actual application, and the application does not limit the size of the specific value.

[0066] Another detection manner is to determine whether the communication channel of the wireless communication device is a boundary communication channel in the communication frequency band, and if so, to detect whether the communication signal between the wireless communication device and the wireless medical device is interfered by the interference signal.

[0067] Specifically, the communication frequency band used by the present medical communication system can be divided into multiple communication channels, and the communication channel can be a boundary communication channel corresponding to the lowest or highest communication frequency band. It can be understood that there will be interference between adjacent communication channels, and the interference between non-adjacent communication channels does not necessarily occur. That is, the boundary communication channel of the present medical communication system is more likely to be interfered by other medical communication systems. Therefore, the wireless communication device can first determine whether its own communication channel is a boundary communication channel, and if so, detect whether the communication signal between the wireless communication device and the wireless medical device is interfered by the interference signal. The detection manner can refer to the first detection manner.

[0068] In this detection manner, not all wireless communication devices in the present medical communication system need to detect the interference signal, only the wireless communication devices using the boundary communication channel need to perform the detection, thereby avoiding waste of resources.

[0069] Of course, this detection manner can also be automatically implemented based on pre-configuration, that is, pre-configure which wireless communication devices use which communication channels, and start the detection process for the wireless communication devices using the boundary communication channel. Only the wireless communication devices starting the detection process will automatically detect whether the communication signal between the wireless communication device and the wireless medical device is interfered by the interference signal, while the wireless communication devices not starting the detection process will not perform the detection, thereby avoiding waste of resources.

[0070] Yet another detection manner is to detect whether the communication state between the wireless communication device and the wireless medical device is a preset suboptimal communication state, and if so, to detect whether the communication signal between the wireless communication device and the wireless medical device is interfered by the interference signal.

[0071] Specifically, the wireless communication device first detects whether the communication state between itself and the wireless medical device is poor, and if the communication state is poor, it indicates that it can be interfered, and then specifically detects whether the communication signal between the wireless communication device and the wireless medical device is interfered by the interference signal. The detection manner can refer to the first detection manner. It should be noted that the wireless communication device can obtain the communication state between the wireless communication device and the wireless medical device, and determine whether the communication state is a preset suboptimal communication state. Of course, the communication state can be detected by the wireless communication device itself, or sent to the wireless communication device by other devices such as the wireless medical device.

[0072] Or, in order to further reduce resource consumption, when the communication state is a preset poor communication state, it is directly determined that the communication signal between the wireless communication device and the wireless medical device is interfered by the interference signal.

[0073] Another detection method is that the notification information sent by the wireless medical device can be received, and when the notification information sent by the wireless medical device is received, it is detected whether the communication signal between the wireless communication device and the wireless medical device is interfered by the interference signal.

[0074] Specifically, the wireless medical device can send notification information to the wireless communication device, which is used to inform the wireless communication device that the communication state between the wireless communication device and the wireless medical device is a preset poor communication state. After receiving the notification message, the wireless communication device can directly determine that the communication state between the two devices is poor, so as to detect whether the communication signal between the wireless communication device and the wireless medical device is interfered by the interference signal. The detection method can refer to the first detection method. This detection method can avoid the wireless communication device to periodically detect whether the communication state is poor, thereby reducing the resource consumption of the wireless communication device.

[0075] Or, in order to further reduce resource consumption, when the wireless communication device receives the notification information sent by the wireless medical device, it is directly determined that the communication signal between the wireless communication device and the wireless medical device is interfered by the interference signal.

[0076] Another detection method is to periodically detect whether the communication signal between the wireless communication device and the wireless medical device is interfered by the interference signal. Specifically, the wireless communication device detects whether the communication signal between the wireless communication device and the wireless medical device is interfered according to a preset detection period. The detection method can refer to the first detection method.

[0077] No matter which detection method is used, if the detection result is to determine that the communication signal between the wireless communication device and the wireless medical device is interfered by the interference signal, the bandwidth of the communication signal and the bandwidth of the interference signal need to be determined. For example, after the wireless communication device receives the digital signal, the frequency domain analysis is performed on the data signal to determine the bandwidth of the interference signal.

[0078] S302: Based on the bandwidth of the communication signal and the bandwidth of the interference signal, the target bandwidth of the communication signal is calculated.

[0079] In order to reduce the interference of the interference signal, the overlapping part of the communication signal and the interference signal can be narrowed. For example, the bandwidth of the communication signal can be reduced by the total bandwidth of the interference signal to obtain the target bandwidth of the communication signal. For another example, the bandwidth of the communication signal can be reduced by the partial bandwidth of the interference signal to obtain the target bandwidth of the communication signal. For another example, the bandwidth of the interference signal can be multiplied by a multiple value greater than 1, and the bandwidth of the communication signal can be reduced by the product value to obtain the target bandwidth of the communication signal.

[0080] As shown in FIG. 3, when the wireless communication device of the WMTS system detects the interference signal of the UHF system, the default bandwidth of the communication channel is reduced by the bandwidth of the interference signal to obtain the target bandwidth of the communication channel. The frequency spectrums of the communication signals of the two systems are almost not overlapped, so that the communication interference between the two systems is reduced. Figure 4A

[0081] S303: Set the channel bandwidth of the wireless communication device as the target bandwidth.

[0082] When the channel bandwidth is set as the target bandwidth, the wireless communication device can transmit and / or receive the communication signal according to the target bandwidth. As shown in FIG. 4, the wireless communication device AP of the WMTS system detects the interference signal of the UHF system, and the default bandwidth of the communication channel is reduced by the bandwidth of the interference signal to obtain the target bandwidth of the communication channel. The frequency spectrums of the communication signals of the two systems are almost not overlapped, so that the communication interference between the two systems is reduced. Figure 4B As shown in FIG. 5, in a specific medical communication system deployment diagram, the wireless communication device APs are distributed near the patient rooms and the nurse stations, and can communicate with the wireless medical devices. Each wireless communication device AP is allocated to use a certain communication channel. Since the communication channel 1 is a boundary communication channel, it will be interfered by the communication signals of the adjacent frequency bands of the other medical communication channels. Therefore, the wireless communication device AP using the communication channel 1 shortens the channel bandwidth to reduce the interference of the other medical communication systems.

[0083] According to the above technical solution, in the case that the medical communication system is interfered by the other medical communication systems, the wireless communication device adjusts the bandwidth of the communication channel according to the bandwidth of the interference signal to reduce or even eliminate the interference received by the wireless communication device. Moreover, the scheme does not need to adjust the network deployment state of the wireless communication device, and does not need manual intervention to exclude the interference source.

[0084] In addition to setting the channel bandwidth of the wireless communication device as the target bandwidth, the wireless communication device can also send setting information to the wireless medical devices connected thereto. The setting information is used to inform the wireless medical devices to set the channel bandwidth as the target bandwidth. After the wireless medical devices set the channel bandwidth as the target bandwidth, the wireless medical devices can transmit and / or receive the communication signal according to the target bandwidth to reduce the interference of the communication signal of the wireless medical devices by the interference signal.

[0085] ​The communication channel bandwidth setting method described above is performed in the communication process between the wireless communication device and the wireless medical device. Of course, the wireless communication device can also adjust the communication channel bandwidth in the communication gap with the wireless medical device. Specifically, see Figure 5 which shows another embodiment of the communication channel bandwidth setting method applied to the wireless communication device, specifically including S501-S504.

[0086] S501: In the communication gap between the wireless communication device and the wireless medical device, it is determined that an interference signal is received, and the communication frequency band of the wireless communication device and the communication frequency band of the wireless medical device at least partially overlap.

[0087] Wherein, the wireless communication device and the wireless medical device can communicate, and the communication process will generate a communication signal. The wireless communication device can determine whether there is interference to the wireless communication device by detecting whether the communication signal is interfered. Of course, the wireless communication device can also scan whether there is an interference signal in the communication gap with the wireless medical device. The interference signal comes from other medical communication systems, and the communication frequency band of the interference signal and the communication frequency band of the wireless communication device may partially overlap or completely overlap.

[0088] S502: Obtain the bandwidth of the communication signal and determine the bandwidth of the interference signal.

[0089] Wherein, in the case of determining that the interference signal is received, the bandwidth of the communication signal and the bandwidth of the interference signal are determined.

[0090] S503: Based on the bandwidth of the communication signal and the bandwidth of the interference signal, the target bandwidth of the communication signal is calculated;

[0091] S504: Set the channel bandwidth of the wireless communication device to the target bandwidth.

[0092] It should be noted that the description of steps S503-S504 of the present embodiment can refer to the description of steps S302-S303 in Figure 3 , which will not be described here. In addition, the wireless communication device can also send notification information to the wireless medical device to indicate the wireless medical device to set the channel bandwidth of the communication channel to the target bandwidth.

[0093] From the above technical solution, it can be seen that in the present embodiment, the wireless communication device can adjust the communication channel bandwidth in the communication gap, avoid the influence of channel bandwidth adjustment on the communication signal in the communication process, and improve the stability of the communication signal.

[0094] The communication channel bandwidth setting method described above is applied to a wireless communication device, which can be connected with one or more wireless medical devices. In the case that the wireless communication device is connected with only one wireless medical device, the method can also be applied to the wireless medical device. Specifically, when the wireless medical device determines that the communication signal between the wireless medical device and the wireless communication device is interfered by an interference signal, the bandwidth of the communication signal and the bandwidth of the interference signal are obtained; the communication signal and the interference signal do not overlap at least in part in the communication frequency band; the target bandwidth of the communication signal is calculated based on the bandwidth of the communication signal and the bandwidth of the interference signal; and the channel bandwidth of the wireless medical device is set as the target bandwidth. Alternatively, the wireless medical device sends notification information to the connected wireless communication device to instruct the wireless communication device to set the channel bandwidth as the target bandwidth.

[0095] Another situation encountered in actual application is that the wireless spectrum resource is very valuable, and the communication channel bandwidth used by the medical communication system needs to be compressed due to the need for sharing spectrum resource and the like. In this way, the number of channels that can be used by the wireless communication device of the medical communication system is reduced, the distance between the wireless communication devices using the same channel is reduced, the co-frequency interference is increased, the communication signal coverage is also poor, and the communication quality of the wireless medical device in the weak network coverage area is poor or even dropped, which has a greater impact on the real-time monitoring scene.

[0096] See Figure 6 which shows a layout scene of a wireless communication device AP in a medical communication system. Due to the adjustment of the communication channel bandwidth, the number of communication channels is changed from 4 to 2, and the communication channels used by the wireless communication device AP are also adjusted accordingly. After the adjustment, the distance between the wireless communication devices AP using the same communication channel is shortened, for example, the distance between two wireless communication devices AP using the same communication channel 1 is shortened from 45 meters to 15 meters, the co-frequency interference is increased, and if the medical communication system works in the frequency band of 1.4 GHz, the typical value of the communication loss caused by the co-frequency interference is 60 dB, which has a greater impact on the communication signal quality of the wireless communication device AP.

[0097] The present application provides a communication channel bandwidth setting method, which is applied to a medical communication system management device. The medical communication system management device can be connected with one or more wireless communication devices, and is used to uniformly manage the wireless communication devices, for example, to configure the network parameters of the wireless communication devices. See Figure 7 The communication channel bandwidth setting method specifically includes steps S701-S705.

[0098] S701: Obtain the total channel bandwidth that needs to be set by the medical communication system.

[0099] The medical communication system management device can obtain a channel total bandwidth input by a user, the channel total bandwidth being a channel total bandwidth that the medical communication system needs to be set to, the channel total bandwidth being smaller than a current channel total bandwidth of the medical communication system. It can be understood that the channel total bandwidth that needs to be set to is an adjusted channel total bandwidth, and the current channel total bandwidth is a channel total bandwidth before adjustment.

[0100] S702: According to the channel total bandwidth, a target channel bandwidth that the wireless communication device needs to be set to is determined.

[0101] The medical communication system includes one or more wireless communication devices, and the channel bandwidth that each wireless communication device needs to be adjusted to needs to be determined. For ease of description, the channel bandwidth that needs to be adjusted to is referred to as a target channel bandwidth. One determination manner is to respectively assign different target channel bandwidths to each wireless communication device, and the target channel bandwidths may or may not overlap. Another determination manner is to assign the same target channel bandwidth to each wireless communication device, and the target channel bandwidths do not overlap. Specifically, the channel total bandwidth is divided by the number of wireless communication devices to obtain the target channel bandwidth that each wireless communication device needs to be set to.

[0102] S703: Based on the target channel bandwidth that the wireless communication device needs to be set to, a first maximum number of wireless medical devices that the wireless communication device can connect to is determined.

[0103] After the target channel bandwidth of the wireless communication device is determined, the wireless communication device can determine the maximum number of wireless medical devices that can be connected under the bandwidth according to the communication bandwidth occupied by the wireless medical device. In an embodiment, the medical communication system can calculate the data size of each monitoring device according to the monitoring information, and can calculate the maximum data size that each wireless medical device needs to have by considering other interactive information overhead. The wireless communication device can calculate the maximum number of wireless medical devices that can be carried according to the total data size corresponding to the channel total bandwidth and the maximum data size that each wireless medical device needs to have. For ease of description, the maximum number can be referred to as a first maximum number. It can be understood that the first maximum number is the maximum number of wireless medical devices that the wireless communication device can connect to after the channel total bandwidth is adjusted. However, the maximum number can exceed the maximum number of wireless medical devices that the wireless communication device can connect to before the channel total bandwidth is adjusted, and if it exceeds, it means that the deployment strategy of the wireless communication device needs to be adjusted, so that step S704 is performed to determine the maximum number before the channel total bandwidth is adjusted, which is referred to as a second maximum number.

[0104] S704: A second maximum number of wireless medical devices that the wireless communication device can connect to under a current channel bandwidth is determined.

[0105] The wireless communication device determines the maximum number of wireless medical devices that can be connected under the current channel bandwidth according to the bandwidth occupied by the communication with the wireless medical devices. It should be noted that the maximum number is the maximum number of wireless medical devices that can be connected by the wireless communication device, not the number of wireless medical devices actually connected by the wireless communication device.

[0106] S705: When the first maximum number is less than or equal to the second maximum number, set the channel bandwidth of the wireless communication device to the target channel bandwidth.

[0107] The first maximum number is compared with the second maximum number. If the first maximum number does not exceed the second maximum number, it means that the target channel bandwidth set for the wireless communication device is appropriate, and the target channel bandwidth is sent to the wireless communication device so that the wireless communication device sets the channel bandwidth to the target channel bandwidth. See Figure 8 , still taking the wireless communication device AP layout scenario shown in Figure 6 As an example, after the total channel bandwidth is shortened, the layout strategy of the wireless communication device AP remains unchanged, but in order to avoid co-channel interference, the wireless communication device AP adjusts its own channel bandwidth. After comparison, it can be found that the adjusted channel bandwidth is narrower.

[0108] From the above technical solutions, it can be seen that the embodiment can adjust the channel bandwidth of the wireless communication device according to the total channel bandwidth and the number of wireless communication devices, and the capacity of the adjusted channel bandwidth meets the connection demand of the wireless medical device. Moreover, the embodiment does not need to adjust the layout strategy of the wireless communication device, thereby saving the network deployment cost.
