[0025] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0026] In order to enable those skilled in the art to use the contents of this application, the following implementation is given in combination with the specific application scenario "identification of ultrasound probe". For those skilled in the art, the general principles defined here can be applied to other embodiments and application scenarios without departing from the spirit and scope of this application.

[0027] The following methods, devices, electronic devices, and computer-readable storage media of the embodiments of the present application can be applied to any scenario requiring identification of an ultrasound probe. The embodiments of the present application are not limited to specific application scenarios, and any solution using the probe identification method and device provided in the embodiments of the present application is within the protection scope of the present application.

[0028] The following will be combined Figure 1 as well as Figure 2 The implementation of the embodiment of the present application is described in detail; the embodiment of the present application provides a probe identification method, which is applied to a host computer of a probe system.

[0029] See also Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the structure of the probe system in the embodiment of the present application when the probe is not connected; Figure 2 Schematic diagram of the structure of the probe system in the embodiment of the present application when the probe is connected. The probe identification method provided in the embodiment of the present application can be applied to Figure 1 and Figure 2 The host computer 110 of the probe system shown in FIG. Figure 1 As shown, the probe system 100 includes a host computer 110 and at least one type of probe 120; a tag reader 111 is installed in the interface of the host computer 110, and an RFID tag 121 is installed on the connector of at least one type of probe 120. Figure 2As shown, the host computer 110 is communicatively connected with at least one model of probe 120 via an RFID tag 121 .

[0030] Here, in the embodiment of the present application, an RFID tag 121, i.e., a Radio Frequency Identification (RFID) tag, is installed on the connector of the probe 120, and a tag reader 111 is installed in the interface between the host computer 110 and the probe 120, so that the probe 120 has readable and writable information management functions.

[0031] The installation position of the tag reader 111 requires that when the interface of the host computer 110 is securely connected to the connector of the probe 120, the receiving antenna position on the interface must be able to communicate with the RFID tag 121 on the probe 120 and read and write correct tag information. Since the tag reader 111 is generally connected to the receiving antenna through a signal line, the tag reader 111 can be placed in different positions according to the space size requirements in the interface of the host computer 110.

[0032] Here, the tag reader 111 is mainly composed of a receiving antenna and a set of microcontroller circuit boards, which are usually placed separately during installation. Figure 2 As shown, the receiving antenna is installed at the position closest to the RFID tag 121 after the probe 120 is inserted, so as to achieve the best signal reception performance, and the microcontroller circuit board is generally placed at other positions of the host computer 110 and connected to the receiving antenna through a signal line.

[0033] Among them, the installation position of the RFID tag 121 can generally be at the end of the connector of the probe 120. The specific position needs to be coordinated with the mechanical structure design of the connector of the probe 120, but it is necessary that the connector is securely connected to the interface of the host computer 110 to communicate with the RFID tag 121 and read and write correct tag information.

[0034] Here, the RFID tag 121 adopts standard RFID technology, and the operating frequency can be a low frequency band of 125-148KHz, a high frequency band of 13-56MHz, an ultra-high frequency band of 860-950MHz, or other suitable frequencies. In the embodiment of the present application, the RFID tag 121 is a passive RFID tag, and does not need to be connected to an external power supply when working. When the RFID tag 121 and the receiving antenna of the tag reader 111 are close to the effective range, the tag reader 111 can use electromagnetic waves through the receiving antenna to provide the required power to the RFID tag 121 to operate, so when the tag reader 111 communicates with the RFID tag 121, it must remain within the effective range, otherwise the communication will be interrupted or the correct information cannot be read.

[0035] A probe identification method provided in an embodiment of the present application is described in detail below. The probe identification method can be applied to the host computer of the above-mentioned probe system.

[0036] See also Figure 3 , Figure 3 This is a flow chart of a probe identification method provided in an embodiment of the present application. Figure 3 As shown, the probe identification method provided in the embodiment of the present application includes the following steps:

[0037] S301, after the probe system starts to work, a first identification signal is sent through the tag reader based on a preset sending frequency.

[0038] Here, in combination with the application scenario of ultrasonic probe identification, the probe system in the embodiment of the present application is an ultrasonic imaging system, the host computer is an imaging host, and the probe is an ultrasonic probe. Specifically, after the ultrasonic imaging system starts working, the imaging host sends a first identification signal through a tag reader based on a preset transmission frequency to establish a communication connection with the RFID tag of the ultrasonic probe. Among them, the first identification signal is an electromagnetic wave signal. In this way, when the ultrasonic probe is connected to the imaging host, the imaging host can determine the model of the ultrasonic probe by reading the preset information in the RFID tag of the ultrasonic probe through the tag reader; and, if the connector of the ultrasonic probe is not correctly inserted into the interface of the imaging host, the tag reader cannot read the tag information returned by the RFID tag of the ultrasonic probe, so the model and connection status of the ultrasonic probe can be judged based on this.

[0039] S302, receiving a first feedback signal returned by an RFID tag of a target probe connected to the host computer, and determining a probe model of the target probe based on the first feedback signal.

[0040] Here, the imaging host receives a first feedback signal returned by the RFID tag of the target probe connected to the imaging host, and determines the probe model of the target probe based on the first feedback signal. Specifically, after receiving the first identification signal, the RFID tag of the target probe generates a corresponding feedback electromagnetic wave signal, i.e., a first feedback signal, according to the electromagnetic wave of the first identification signal. The first feedback signal carries preset information of the target probe pre-stored in the RFID tag. The preset information may be the operating frequency type information of the target probe. For example, the RFID tag of the ultrasonic probe of the first probe model may pre-write its 12MHz operating frequency type, and the RFID tag of the ultrasonic probe of the second probe model may pre-write its 20MHz operating frequency type, and then the imaging host may extract the operating frequency type information from the first feedback signal, and then determine the probe model of the target probe.

[0041] S303: Determine a connection status between the target probe and the host computer based on the first feedback signal and the received signal strength indicator value of the first feedback signal.

[0042] Here, when the connector of the target probe is inserted into the interface of the imaging host, the RFID tag of the ultrasound probe will move from a farther distance to the receiving antenna of the tag reader to a closer distance. As a result, the tag reader will go from not receiving the first feedback signal to correctly receiving the first feedback signal and correctly reading the feedback information, and the received signal strength indication (RSSI) value of the first feedback signal will change from weak to strong. Therefore, the connection status of the target probe and the imaging host can be determined by the first feedback signal and the received signal strength indication value of the first feedback signal.

[0043] Further, the determining the connection state between the target probe and the host computer based on the first feedback signal and the received signal strength indicator value of the first feedback signal includes:

[0044] Step a1, before sending the first identification signal of the preset first number of times, if the first feedback signal of the preset second number of times is continuously and correctly received, and the received signal strength indication value of each of the first feedback signals of the second number of times is greater than or equal to the preset target received signal strength indication value, it is determined that the target probe is correctly connected to the host computer.

[0045] Here, since the ultrasonic probe may cause unstable reading of the first feedback signal during the movement of the connection, it may happen that the first feedback signal can be read sometimes but then cannot be read, and if the ultrasonic probe is not completely connected to the imaging host, a virtual connection may occur, and the RSSI value of the first feedback signal is low at this time. Therefore, to identify whether the ultrasonic probe is correctly connected to the imaging host, the connection status can be judged by the reception of the first feedback signal when the tag reader communicates with the RFID tag and the RSSI reception value of the first feedback signal. That is, if the first feedback signal with a high RSSI value can be received continuously and correctly for a certain number of times, it can be determined that the ultrasonic probe is correctly connected to the imaging host. Specifically, before sending the first identification signal of the preset first number of times, if the first feedback signal of the preset second number of times is continuously and correctly received, and the received signal strength indication value of each second number of the first feedback signal is greater than or equal to the preset target received signal strength indication value, it is determined that the target probe is correctly connected to the imaging host. Among them, the first number is the preset upper limit value of the first identification signal sent, which avoids the waste of resources and affects the service life of the tag reader by continuously sending invalid first identification signals when the connection fails; the second number and the target received signal strength indication value can be set according to the actual application situation and are not limited here.

[0046] Step a2, after sending the first identification signal a preset first number of times, if the first feedback signal a second number of times is still not continuously and correctly received, or the received signal strength indication value of any of the first feedback signals a second number of times is less than the target received signal strength indication value, it is determined that the target probe has failed to connect with the host computer.

[0047] Here, after sending the first identification signal of the first number, if the first feedback signal of the second number is still not continuously and correctly received, or the RSSI value of any first feedback signal of the second number is less than the target RSSI value, it means that the connection between the target probe and the imaging host is unstable. At this time, in order to ensure the accuracy and safety of the ultrasonic imaging detection, it is determined that the connection between the target probe and the imaging host has failed. At this time, a prompt message indicating that the target probe connection has failed can be output to prompt the operator to adjust or replace the ultrasonic probe.

[0048] Further, after determining that the target probe is correctly connected to the host computer, the method further includes:

[0049] Step b1, sending a second identification signal through the tag reader.

[0050] In the embodiment of the present application, the writable function of the RFID tag can also be used to record the number of times each ultrasound probe is used. Here, each time the ultrasound probe is successfully connected to the imaging host, the imaging host first sends a second identification signal through the tag reader. Specifically, the second identification signal is an electromagnetic wave signal, which is used to read the number of times information written in the RFID tag.

[0051] Step b2, receiving a second feedback signal returned by the RFID tag of the target probe, and determining the number of times the target probe is used based on the second feedback signal.

[0052] Here, the second feedback signal returned by the RFID tag of the target probe is received, and the number of times the target probe is used is determined based on the second feedback signal. Specifically, the RFID tag of the target probe has the number of times the target probe is used written in it. After receiving the second identification signal, the RFID tag of the target probe will generate a second feedback signal carrying the number of times information. After receiving the second feedback signal, the tag reader will extract the number of times information therein to determine the number of times the target probe is used.

[0053] Step b3: sending a first write signal through the tag reader, so that the RFID tag of the target probe increases the number of times the target probe is used by one after receiving the first write signal.

[0054] Here, each time the imaging host determines that the target probe is successfully connected, the usage count information in the RFID tag of the target probe is first read through the tag reader, and then the current usage count is updated and rewritten into the RFID tag of the target probe for storage, ensuring that the updated usage count can be saved after the target probe is pulled out, so that the target probe can accurately read and save the new usage count after it is successfully connected to the imaging host during the next ultrasonic detection. Specifically, a first write signal is sent through the tag reader so that the RFID tag of the target probe increases the usage count of the target probe once after receiving the first write signal. The first write signal is an electromagnetic wave signal, which is used to write and update the usage count of the target probe. In this way, the usage of the target probe can be further judged based on the usage count of the target probe.

[0055] Further, after determining that the target probe is correctly connected to the host computer, the method further includes:

[0056] If the number of times that the first feedback signal is not received continuously reaches a preset third number, it is determined that the target probe is disconnected from the host computer.

[0057] Here, if the number of times the first feedback signal has not been received continuously reaches the preset third number, it means that the target probe has been detached from the imaging host, and it is determined that the target probe is disconnected from the imaging host. At this time, a prompt message that the target probe is disconnected from the imaging host can be output to prompt the operator that the target probe has fallen off or the target probe has been successfully disconnected. Specifically, the target probe may be disconnected from the imaging host due to a fault or the operator actively disconnects it after the ultrasonic imaging test is completed. The corresponding prompt message output is selected according to the specific situation.

[0058] Further, after determining that the target probe is disconnected from the host computer, the method further includes:

[0059] Step c1: if it is determined again within a preset time interval that the target probe is correctly connected to the host computer, then after determining the number of times the target probe has been used based on the second feedback signal, the first write signal is no longer sent through the tag reader.

[0060] Here, if it is determined again within a preset time interval that the target probe is correctly connected to the imaging host, it means that this connection is a reconnection after the target probe falls off. Then, after determining the number of times the target probe has been used based on the second feedback signal, the first write signal is no longer sent through the tag reader to avoid repeated writing of the number of times used in one ultrasonic test. Specifically, since the ultrasonic probe requires a long time for disinfection after use, if the target probe is successfully connected again within a preset time interval that is less than the time required for the disinfection operation, it can be proved that this connection is a connection for the same ultrasonic test, not a connection for the second ultrasonic test after the ultrasonic test is completed.

[0061] Step c2: if it is determined again outside the preset time interval that the target probe is correctly connected to the host computer, the first write signal is sent again through the tag reader after determining the number of times the target probe has been used based on the second feedback signal.

[0062] Here, if it is determined again that the target probe is correctly connected to the imaging host outside the preset time interval, it means that this connection is the reconnection of the second ultrasonic imaging test after the target probe has completed the ultrasonic imaging test and undergone the disinfection operation. Then, after determining the number of times the target probe has been used based on the second feedback signal, the first write signal is sent again through the tag reader to update the number of times the target probe has been used.

[0063] Further, after determining the number of times the target probe is used based on the second feedback signal, the method further includes:

[0064] Step d1: If the usage count of the target probe is greater than a preset usage count threshold, it is determined that the target probe cannot be used any further.

[0065] Here, since each model of ultrasonic probe has a corresponding service life of a certain number of uses, if the number of uses exceeds the number of uses specified in the service life, various quality problems such as inaccurate detection may occur. Therefore, if the number of uses of the target probe is greater than the preset usage threshold, it is determined that the target probe cannot continue to be used.

[0066] Step d2, outputting a first prompt message; wherein the first prompt message is used to prompt that the probe needs to be replaced due to exceeding the usage limit.

[0067] Here, after determining that the target probe cannot be used any more, the first prompt information is outputted, wherein the first prompt information is used to prompt the operator that the target probe needs to be replaced because the number of times it has been used exceeds the limit of its service life.

[0068] Further, after determining that the target probe is correctly connected to the host computer, the method further includes:

[0069] Step e1, sending a third identification signal through the tag reader.

[0070] Here, the RFID tag of the target probe can also carry the first use date information of the target probe. Since each model of ultrasonic probe has a corresponding shelf life limit after unpacking, even if the number of uses of the target probe is within the limit, the target probe will be placed for a period of time exceeding the corresponding shelf life after unpacking, which will also cause various quality problems. Therefore, when the target probe is successfully connected to the imaging host for the first time, the first use date information of the target probe will be written to the RFID tag of the target probe through the tag reader. This writing is a one-time writing, and the first use date information cannot be changed after writing. After confirming that the target probe is correctly connected to the imaging host again after the first connection, a third identification signal is sent through the tag reader. Among them, the third identification signal is an electromagnetic wave signal, which is used to identify the first use date information in the RFID tag of the target probe.

[0071] Step e2, receiving a third feedback signal returned by the RFID tag of the target probe, and determining the first use date of the target probe based on the third feedback signal.

[0072] Here, the third feedback signal returned by the RFID tag of the target probe is received, and the first use date of the target probe is determined based on the third feedback signal. Specifically, the first use date information of the target probe is written in the RFID tag of the target probe. After receiving the third identification signal, the RFID tag of the target probe will generate a third feedback signal carrying the first use date information. After receiving the third feedback signal, the tag reader will extract the first use date information therein to determine the first use date of the target probe.

[0073] Step e3, determining whether the usage time of the target probe exceeds a preset shelf life according to the first usage date of the target probe.

[0074] Here, the usage time of the target probe is calculated according to the first usage date of the target probe and the usage date when the connection is successful, and it is determined whether the usage time of the target probe exceeds the preset shelf life.

[0075] Step e4: If yes, it is determined that the target probe cannot be used any further.

[0076] Here, if the shelf life has expired, it is determined that the target probe cannot be used any more.

[0077] Step e5, outputting a second prompt message; wherein the second prompt message is used to prompt that the probe needs to be replaced due to expiration of the shelf life.

[0078] Here, after determining that the target probe cannot be used any more, the second prompt information is outputted, wherein the second prompt information is used to prompt the operator that the target probe needs to be replaced due to the expiration of the shelf life.

[0079] The embodiment of the present application provides a method for identifying a probe, which is applied to a host computer of a probe system; the probe system includes a host computer and at least one type of probe; a label reader is installed in the interface of the host computer, and an RFID label is installed on the connector of at least one type of probe; the host computer is connected to the at least one type of probe through an RFID label communication; the method includes: after the probe system starts working, based on a preset transmission frequency, a first identification signal is sent through the label reader; a first feedback signal returned by an RFID label of a target probe connected to the host computer is received, and based on the first feedback signal, the probe model of the target probe is determined; based on the first feedback signal and the received signal strength indicator value of the first feedback signal, the connection state of the target probe and the host computer is determined. In this way, the probe model and connection state of the probe are determined by the feedback signal of the RFID label and the received signal strength indicator value of the feedback signal, thereby improving the accuracy of the probe connection identification.

[0080] Based on the same application concept, the embodiments of the present application also provide a probe identification device corresponding to the probe identification method provided in the above embodiments. Since the principle of solving the problem by the device in the embodiments of the present application is similar to the probe identification method in the above embodiments of the present application, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be repeated.

[0082] The sending module 410 is used to send a first identification signal through the tag reader based on a preset sending frequency after the probe system starts working.

[0083] The receiving module 420 is used to receive a first feedback signal returned by the RFID tag of the target probe connected to the host computer, and determine the probe model of the target probe based on the first feedback signal.

[0084] The determination module 430 is used to determine the connection status between the target probe and the host computer based on the first feedback signal and the received signal strength indicator value of the first feedback signal.

[0085] Further, when the determination module 430 is used to determine the connection state between the target probe and the host computer based on the first feedback signal and the received signal strength indicator value of the first feedback signal, the determination module 430 is specifically used to:

[0086] Before sending the first identification signal of the preset first number of times, if the first feedback signal of the preset second number of times is continuously and correctly received, and the received signal strength indicator value of each of the first feedback signals of the second number of times is greater than or equal to the preset target received signal strength indicator value, it is determined that the target probe is correctly connected to the host computer;

[0087] After sending the first identification signal a preset first number of times, if the first feedback signal a second number of times is still not continuously and correctly received, or the received signal strength indication value of any of the first feedback signals a second number of times is less than the target received signal strength indication value, it is determined that the connection between the target probe and the host computer has failed.

[0088] For further information, see Figure 5 , Figure 5 This is a second functional module diagram of a probe identification device provided in an embodiment of the present application.
