firstly, medical equipment and an AP are required to approach and establish NFC communication, and if the medical equipment is large in size, implementation is difficult;
second, the function of establishing NFC communication is simply to transfer network information, which increases cost and yields limited benefits;
thirdly, once the AP replaces the password, the medical equipment needs to be re-close to the AP to establish NFC connection to update the password information, and new inconvenience is brought to the user.
Thus, a new mechanism is needed to address the automatic WLAN connection of medical devices.

Also, various steps or acts in the method descriptions may be interchanged or modified in a manner apparent to those of ordinary skill in the art. Thus, the various orders in the description and drawings are for clarity of description of only certain embodiments, and are not meant to be required orders unless otherwise indicated.
The numbering of the components itself, e.g. "first", "second", etc., is used herein merely to distinguish between the described objects and does not have any sequential or technical meaning. The terms "coupled" and "connected," as used herein, are intended to encompass both direct and indirect coupling (coupling), unless otherwise indicated.
The wireless power supply technology is a non-contact wireless energy transmission mode, and comprises a transmitting end and a receiving end, wherein the transmitting end and the receiving end transmit energy from the transmitting end to the receiving end through an energy transmission medium such as an electromagnetic field to charge a battery or supply power to equipment, and the wireless power supply is also called wireless power supply in some occasions. With the development of wireless charging technology, more and more medical devices are simultaneously configured with wireless charging and WLAN functions, but in these medical devices, the wireless charging and WLAN functions are not directly connected, and the functions are independent of each other. Based on the above, and in combination with the problems of the existing medical equipment in the automatic WLAN connection, the inventor of the present application proposes an automatic WLAN connection method and related system based on wireless power supply connection.
As shown in fig. 1, the medical device automatic networking system 10 of an embodiment of the present application includes a gateway 100, a medical device 200, and a wireless power transmitting terminal 301.
Gateway 100 has wireless and/or wired connectivity to connect devices connected thereto. In one embodiment, the gateway 100 may include a processor, a memory, a wireless communication module (such as a WIFI module), a USB interface, a power module, and the like, where the processor of the gateway 100 may use an embedded operating system Linux, iOS, or Android OS, may process protocols and data of different communication modules, run various application programs, and the like, and the WIFI module of the gateway 100 may enable a wireless local area network where the gateway 100 is currently located to access another WIFI network, and the USB interface of the gateway 100 may be used to extend other wireless communication modules, such as a 2.4GHz wireless module, a ZigBee module, a Z-wave module, and the like.
The medical device 200 may be, for example, an ultrasound imaging device, a mobile DR (Digital Radiography ) device, or the like, which includes a wireless power supply receiving end 201, a host 202, a wireless communication interface 203, and a network communication interface (not shown), and has a WLAN function and a wireless power supply function. In one embodiment, the wireless charging receiver 201 mainly includes a wireless power receiving circuit and a wireless power receiving coil, which are used to supply the received electric energy to the rest components of the medical device 200.
In the embodiment shown in fig. 1, the wireless power transmitting terminal 301 is already connected to the access gateway 100 by a wired or wireless means.
In one example, the wireless power supply transmitting end 301 joins the lan by connecting to the gateway 100 in a wired manner, where a DHCP module in the lan allocates an IP address to the wireless power supply transmitting end 301 and obtains its MAC address, and then establishes a network connection, so that the wireless power supply transmitting end 301 can learn information such as a password required for WLAN connection. This may be accomplished with reference to existing related network technology, which is not limiting in this application.
In another example, the wireless power transmitting terminal 301 is connected to the gateway 100 by wireless connection to join the lan, and may access the lan through, for example, the information terminal 400 shown in fig. 3. For example, a pre-programmed special management program exists in the wireless power supply transmitting end 301 to realize a network connection function, when the wireless power supply transmitting end 301 is not connected to a network, the wireless power supply transmitting end 301 can be automatically converted into a wireless hot spot for connection, the wireless power supply transmitting end 301 can be directly found and used as a router to be connected by using the information terminal 400, a connection password of the wireless power supply transmitting end 301 needs to be input in the connection process, then the special management program on the information terminal 400 finds the wireless power supply transmitting end 301 and configures a real router, a router connection password and other information (such as a user name) needed to be connected for the wireless power supply transmitting end 301, and the wireless power supply transmitting end 301 can join a local area network through the real router. Here, each specific hypervisor may be written with reference to the prior art, as long as it can realize the functions described above, which the present application does not limit.
In the case where the wireless power transmitting terminal 301 has joined the lan, it is obvious that the wireless power transmitting terminal 301 can learn information such as the password of the gateway 100.
In the embodiment shown in fig. 1, a wireless power transmitting terminal 301 is paired with a wireless power receiving terminal 201. In one example, the wireless power transmitting terminal 301 is connected to the wireless power receiving terminal 201 through wireless power private communication, and the wireless power private communication connection mode is a wireless power communication link, which can implement information transmission to enable the wireless power transmitting terminal 301 and the wireless power receiving terminal 201 to establish a wireless pairing connection, besides being capable of transmitting electric energy. For example, the wireless power supply receiving terminal 201 broadcasts a power supply requirement to surrounding wireless power supply transmitting terminals 301, and the wireless power supply transmitting terminals 301 may receive the power supply requirement to respond to complete pairing. In another example, the wireless power supply transmitting end and the wireless power supply receiving end are respectively provided with a wireless communication unit for realizing high-speed transmission of a large amount of data; in some embodiments of the present application, the transmission of networking information is accomplished through a wireless power supply communication link, i.e., a dedicated communication path that the wireless power supply has, without going through the wireless communication unit.
In one embodiment, the wireless power transmitting terminal 301 mainly includes a wireless power transmitting circuit and a wireless power transmitting coil, so as to transmit electric energy to the wireless power receiving terminal 201 according to requirements.
In another embodiment, the medical device automatic networking system 10 has a plurality of wireless power supply transmitting terminals, where each wireless power supply transmitting terminal corresponds to a wireless power supply receiving terminal of a different medical device and is paired for use, for example, before the wireless power supply receiving terminal 201 of the medical device 200 and the wireless power supply transmitting terminal 301 implement wireless power supply, whether the medical device is an authorized device or not may be confirmed through a wireless power supply private communication connection, if the medical device is the authorized device, power is provided to implement wireless power supply, and if the medical device is not the authorized device (the authorized device refers to the medical device 200 corresponding to the wireless power supply receiving terminal 201 to which the wireless power supply transmitting terminal 301 prestores, which is paired), power is not provided. For example, the wireless power supply transmitting end transmits the identification signal, and the wireless power supply receiving end senses and distinguishes the identification signal; or the wireless power supply receiving end sends out the identification signal, and the wireless power supply transmitting end receives and distinguishes the identification signal to determine whether the opposite side authorizes the equipment, thereby realizing the mutual pairing of the two. The pairing between the wireless power supply transmitting end and the wireless power supply receiving end, power transmission and the like can be realized by referring to the prior art, and the application is not limited to the pairing. In one embodiment, the wireless power transmitting end is typically fixedly mounted to a wall or other object.
After the wireless power transmitting terminal 301 and the wireless power receiving terminal 201 are paired, a wireless power communication path exists between the two terminals, which is used for transmitting electric energy, and is used for transmitting information such as a password and the like required by the WLAN connection. When the medical device 200 approaches to the wireless power supply transmitting end 301, the wireless power supply module of the wireless power supply transmitting end 301 will determine whether the medical device 200 is an authorized device, if so, start wireless power supply and send information such as a gateway password to the host 202 of the medical device 200, so that a management program (which is burned in the medical device in advance to realize a network connection function) running in the host 202 of the medical device 200 connects with the gateway AP according to the gateway AP information and establishes WLAN connection; if the device is not authorized, the wireless power module of the wireless power transmitting terminal 301 will not provide wireless power and will not send gateway AP information. Here, the management program running in the host 202 of the medical device 200 may refer to the related art as long as it can realize the functions described previously, which the present application does not limit. In addition, the communication protocol between the wireless power transmitting terminal 301 and the gateway 100, and the communication protocol between the medical device 200 and the gateway 100 may be any available communication protocol known in the art, which is not limited in this application.
In the embodiment shown in fig. 1, after the wireless power supply transmitting end 301 passes through the wired/wireless connection gateway 100, when the medical device 200 approaches, the wireless power supply transmitting end 301 determines whether the medical device 200 authorizes the device, if so, the gateway AP information is transmitted through the wireless power supply communication path, so that the medical device 200 automatically establishes a connection with the gateway 100 according to the acquired gateway AP information; therefore, the network connection can be completed without manual operation of a user each time, and meanwhile, the NFC hardware cost is not required to be additionally increased.
Based on the medical device automatic networking system shown in fig. 1, an embodiment of the present application provides a method for automatically connecting a medical device to a WLAN, as shown in fig. 2, the method includes the following steps:
step S10: and enabling the wireless power supply transmitting terminal to be connected with the gateway, namely establishing connection between the wireless power supply transmitting terminal and the gateway. The specific connection is established as described above, and will not be described here again.
Step S11: and the wireless power supply transmitting terminal acquires networking information of the gateway from the gateway after being connected.
Step S20: the wireless power supply transmitting terminal is enabled to distinguish whether the medical equipment which enters the power supply range is authorized equipment or not. This is an authentication step, as previously described, and the pairing between a particular wireless power transmitting end and a wireless power receiving end of a medical device is not described in detail herein.
Step S30: after the wireless power supply transmitting end determines that the medical equipment is the authorized equipment, a wireless power supply communication link is established between the medical equipment and the wireless power supply transmitting end so as to wirelessly supply power to the medical equipment, and networking information is transmitted to a wireless power supply receiving end of the medical equipment through the wireless power supply communication link.
Step S40: the wireless communication interface of the medical equipment is automatically connected with the gateway according to the networking information received by the wireless power supply receiving end.
As described above, by the method for automatically connecting the medical device to the WLAN shown in fig. 2, the medical device can automatically connect to the gateway while realizing wireless power supply, and only authorized medical devices can supply power and network, thereby ensuring the security of network communication.
As shown in fig. 3, the medical device automatic networking system 10 according to another embodiment of the present application includes a gateway 100, a medical device 200, a wireless power supply transmitting terminal 301, and an information terminal 400. The functions of the gateway 100, the medical device 200, and the wireless power transmitting terminal 301 are the same as those of the embodiment shown in fig. 1, and will not be described herein. The information terminal 400 may be a personal computer, a server, a smart phone, or the like used by a user.
In the embodiment shown in fig. 3, the information terminal 400 is connected to the gateway 100, and the specific connection implementation is referred to in the prior art, which is not limited in this application. In the present embodiment, the information terminal 400, the wireless power supply transmitting terminal 301, and the medical device 200 each have a dedicated management program running therein, and the three are communicated with each other by the respective dedicated management programs.
The special management program running in the wireless power transmitting terminal 301 can realize not only the function of connection with the wireless power receiving terminal 201 and the gateway 100 (as described in the embodiment shown in fig. 1), but also the communication with the information terminal 400.
The specialized management program running in the medical device 200, like the embodiment shown in fig. 1, may perform its function of connection with the wireless power transmitting terminal 301 and the gateway 100.
The special management program running in the information terminal 400 may not only implement the wireless access gateway 100 for the wireless power transmitting terminal 301 described in the embodiment shown in fig. 1 (described in the embodiment shown in fig. 1), but also in this embodiment, the information such as the password for the gateway 100 may be manually or automatically set and modified by the user through the special management program running in the information terminal 400. In addition, the modified information can be stored in an encrypted manner by a special management program running in the information terminal 400, so that the information can be read only after being logged in by the management program.
Here, each specific hypervisor may be written with reference to the prior art, as long as it can realize the functions described above, which the present application does not limit.
In the embodiment shown in fig. 3, the wireless power transmitting terminal 301 communicates with the management program of the information terminal 400 through its management program, and obtains information such as the password of the gateway 100. Then, similar to the description of the embodiment shown in fig. 1, after the medical device 200 approaches to the wireless power supply transmitting end 301, the wireless power supply module of the wireless power supply transmitting end 301 determines whether the medical device 200 is an authorized device, if so, starts wireless power supply and sends information such as a gateway password to the host 202 of the medical device 200, and the management program running in the host 202 of the medical device 200 connects the gateway AP according to the AP information of the gateway 100 and establishes WLAN connection; if not an authorized device, wireless power transmitting end 301 does not provide wireless power and does not send gateway AP information.
In one embodiment, when the information terminal 400 changes the information such as the password of the gateway 100, the wireless power transmitting terminal 301 communicates with the management program of the information terminal 400 through the management program thereof, and obtains the changed information such as the password, and the WLAN connection between the medical device 200 and the gateway 100 is disconnected due to the password unpaired; thus, when wireless power is again applied, the management program of the wireless power transmitting terminal 301 will re-transmit information such as a new password to the host 202 of the medical device 200, so that the medical device 200 re-establishes a connection with the gateway 100.
In another embodiment, after the information terminal 400 changes the information such as the password of the gateway 100, the WLAN connection between the medical device 200 and the gateway 100 is disconnected due to the password mismatch, and when the wireless power is applied again, the management program of the wireless power transmitting terminal 301 will acquire the new information such as the password from the information terminal 400 again and send the new information to the host 202 of the medical device 200 to reestablish the connection.
Compared with the traditional mode of adopting NFC to transfer gateway AP information, the medical equipment automatic networking system of the embodiment shown in the figure 3 does not need to additionally increase NFC hardware cost, and can complete network information updating in normal use of a user without special operation. In particular, for medical devices, such as ultrasound images, mobile DR devices, etc., the volume and weight are usually relatively large, and if the conventional NFC method is used, alignment is difficult, operation is inconvenient, and in addition, when information such as passwords is changed, special operations are required to update the information; the medical equipment automatic networking system automatically completes information updating when the wireless power supply function is normally used.
Based on the medical device automatic networking system shown in fig. 3, an embodiment of the present application provides a method for automatically connecting a medical device to a WLAN, as shown in fig. 4, the method includes the following steps:
step S100: the information terminal is accessed to the network and is connected with the gateway;
step S101: the information terminal acquires networking information of the gateway;
step S110: the wireless power supply transmitting terminal is communicated with the information terminal, and the communication mode between the wireless power supply transmitting terminal and the information terminal is as described above and is not repeated;
step S111: the wireless power supply transmitting terminal acquires networking information from the information terminal;
step S120, step S130, and step S140: similar to the aforementioned step S20, step S30 and step S40, the description thereof is omitted.
In one embodiment, the wireless power supply transmitting end 301 may also directly obtain the networking information from the gateway 100, for example, send an access request for obtaining the networking information to the gateway 100, and the gateway 100 sends the networking information to the wireless power supply transmitting end 301 in response to the access request.
According to the embodiments of fig. 3 and 4, if the networking information is changed (e.g., the networking information is reconfigured by the information terminal), the wireless power transmitting terminal 301 may obtain the changed networking information through the information terminal 400.
Based on this, in one embodiment, as shown in fig. 5, the method for automatically connecting the medical device to the WLAN further includes:
step S201: enabling the wireless power supply transmitting terminal 301 to actively transmit handshake signals to the gateway 100 at preset time intervals;
step S202: if the handshake signal is failed to be sent, after the handshake signal is failed to be sent, the wireless power supply transmitting terminal 301 is caused to send a networking information request message to the information terminal 400;
step S203: causing the wireless power supply transmitting terminal 301 to receive updated networking information from the information terminal 400;
step S204: the wireless power supply transmitting terminal 301 is caused to transmit updated networking information to the wireless power supply receiving terminals 201 paired in the power supply range thereof, so that the corresponding medical device 200 reestablishes connection with the gateway 100 according to the updated networking information. In one implementation, the wireless power transmitting terminal 301 transmits updated networking information while power is being supplied; in another implementation, the wireless power supply transmitting terminal 301 can actively transmit updated networking information to the wireless power supply receiving terminals 201 paired within its power supply range after receiving the updated networking information even if power is not supplied to the medical device 200 at this time.
Based on the embodiment shown in fig. 5, in the automatic networking system of a medical device according to one embodiment, the wireless power supply transmitting end may be configured to actively send a handshake signal to the gateway at intervals of a preset time, and receive a response from the gateway, and after failure to send the handshake signal, send a networking information request message to the information terminal, receive updated networking information from the information terminal, and send the updated networking information to the wireless power supply receiving end paired in a power supply range.
