BEST MODE FOR CARRYING OUT THE INVENTION

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

1 and FIG. 2, FIG. 1 is a structural block diagram of a probe of a wireless fetal heart rate Doppler ultrasound system according to an embodiment of the present invention; and FIG. 2 is a structural block diagram of a host of a wireless fetal heart rate Doppler ultrasound system.

The invention provides a wireless fetal heart rate Doppler ultrasound system, which mainly comprises a server, a host and a plurality of probes; data transmission can be performed between the server and the host, and data transmission can also be performed between the server and each probe.

Multiple probes operate independently, and fetal heart monitoring can be performed separately for different pregnant women; each probe can be connected to the server and assigned different IP addresses by the server; after each probe acquires the IP address assigned by the server, generate two The dimension code; that is, the two-dimensional code generated by each probe is different, and the IP address information of the probe is hidden in the two-dimensional code; the host can scan each of the two-dimensional codes separately to distinguish each Probes; when the probes are operated independently, each probe acquires monitoring information and transmits the monitoring information to the server and transmits it to the host by the server; in this process, the monitoring information contains the IP address of the probe corresponding to it. After the information is transmitted to the host, the host can distinguish each probe according to the two-dimensional code that has been scanned before, that is, which probe belongs to which probe can be distinguished by the host.

At present, the wireless fetal heart rate Doppler ultrasound system often uses the Bluetooth protocol to communicate the mobile phone terminal, the upper computer and the wireless probe for information interaction, and the Bluetooth protocol can only perform one-to-one connection, which cannot simultaneously make the upper computer or the mobile terminal Multiple wireless probes can be connected, and multiple sets of fetal heart data cannot be acquired at the same time. In view of this, using the WIFI protocol will be the key technology to solve this problem. The WIFI protocol can ensure that one host corresponds to a wireless probe and simultaneously exchanges information. However, the connection process of the WIFI protocol is more complicated. The concept of the IP address and MAC address is very strange to the user. If the user does not understand, it is easy to be bound by this concept, and the wireless probe based on the WIFI protocol cannot be operated well. The system, together with the wireless fetal heart probe itself, omits the information input device, such as buttons, keyboards, etc., in order to reduce the size and weight. Therefore, the WIFI protocol is applied to the ultrasound Doppler wireless fetal heart probe system, if not To solve the problem of convenient connection between the probe and the host computer and the mobile terminal, the advantages brought by the WIFI protocol will be offset by the complicated operation process, which reduces the user's interest in use and limits the user's enthusiasm for use.

Furthermore, in the application scenario of multiple wireless probes, it is very difficult for the user to connect to a probe or interrupt the connection of a certain probe. The only difference between the wireless probes is their IP address, which is in the upper position. On the machine or mobile phone, the user can see the IP address or the information derived from the IP address. It is not clear that the information corresponds to the actual probe, because each wireless probe may be consistent in appearance. . Therefore, the operator may also need to find the corresponding probe, according to the specific display information on the probe, and then find the device information corresponding to the probe on the upper computer or the mobile phone end, and then connect, disconnect, communicate, etc. on the device. Operation is rather cumbersome.

In the wireless fetal heart rate Doppler ultrasound system provided by the present invention, during the user's use, the probe generates a two-dimensional code image according to the IP address provided by the server, and the user can use the mobile phone or the upper computer (ie, the host computer). The two-dimensional code scanning system scans the two-dimensional code generated by the probe to process the connection between the upper computer, the mobile phone and the wireless probe. In this way, the user does not need to know the IP address of the wireless probe when the user needs to connect, disconnect, or transmit data, and the connection between the probe and the upper computer and the mobile terminal can be completed by using a “sweep” method. operating.

Of course, the probe should be provided with a probe display 12 for displaying a two-dimensional code, and a probe WIFI module 11 for connecting to the server. That is, when the probe is powered on, the probe WIFI module 11 checks whether there is a server around. If it is detected that there is a host part (that is, a server) of the system, the probe is connected to the server according to the factory setting access to the hot spot generated by the server. Obtain the IP address information returned by the server. A two-dimensional code of the IP address is generated based on the IP address. The two-dimensional code is displayed on the probe display screen 12, and waits for the mobile phone or the upper computer (ie, the host computer) to perform a scan code connection.

In addition, the probe further includes an MCU 10, and the MCU 10 is sequentially connected to the ultrasonic pulse transmitting circuit 13, the ultrasonic transducer 14 and the fetal heart signal demodulating circuit 15, and the fetal heart signal demodulating circuit 15 is connected to the MCU 10; the battery power supply circuit 16 can The probe is powered, as shown in Figure 1 of the specification; the arrangement of the above various components can be referred to the prior art.

The host computer is provided with a host WIFI module 23 for connecting to the server, and a host display screen 22 capable of separately displaying monitoring information monitored by different probes; of course, in order to realize scanning of the two-dimensional code, two-dimensional code should also be provided. Code scanner 21.

That is, when the server is powered on, after establishing a hotspot, it waits for the surrounding probes to access the server and then assigns it to its corresponding IP address. When the user needs to connect the probe, the user waits for the user to use the mobile phone or the two-dimensional code scanner 21 of the upper computer (ie, the host computer) to scan the two-dimensional code generated on the single or multiple probes, thereby obtaining the IP address corresponding to the probe, and get in touch. The server sends instructions to the probe and receives the information detected by all probes via the WIFI protocol. When the user needs to disconnect the probe, first, the user waits for the QR code scanner 21 to scan the two-dimensional code on the wireless probe that needs to be disconnected, and then acquires the IP address of the probe, and then sends a stop command to the probe, and then Disconnect the probe.

As can be seen from the above, the host can be specifically a mobile terminal or a PC end, thereby facilitating connection and acquisition of monitoring information monitored by the probe.

The above monitoring information is specifically digital information and/or graphic information, and the host further has an external interface 24 for transmitting the monitoring information in hardware. The two-dimensional code scanner 21, the host display screen 22, the host WIFI module 23 and the external interface 24 are all connected to the embedded main board 20, as shown in FIG. 2 of the specification.

The above connection manner can refer to the prior art, and the embedded main board 20 can have various setting manners according to the specific form of the host; the host display screen 22 can respectively display the data monitored by each probe, and each probe is provided. The monitored data are separately displayed for convenient observation; at the same time, the monitoring information is specifically digital information and/or graphic information, which can be displayed in a digital form or in a graphical manner, so that the user can observe the monitoring information in real time according to his own habits; The external interface 24 can be inserted into a mobile storage setting such as a USB flash drive to copy all monitoring information.
