In creating the second command transmission channel, the control program 11 creates a third command transmission channel port, and the second control unit 222 creates a fourth command transmission channel port, with the virtual channel between the third command transmission channel port and the fourth command transmission channel port being the second command transmission channel. When the second command transmission channel is used to transmit the first parameter control command, if the terminal 1 receives the parameter control command based on the wireless network 3 between the terminal 1 and the second control unit 222, the parameter control command is analyzed to obtain the channel port information indicated by the parameter control command; if the port information indicates a third command transmission port, the parameter control command is a first parameter control command, and the first parameter control command is sent to the control program 11 through the third command transmission port.

Next, a description will be given of a process in which the ultrasound scanning apparatus 2 performs a scanning task based on the second parameter control command.

Referring to fig. 10, the process of the ultrasound scanning apparatus 2 performing the scanning task based on the second parameter control command includes at least steps 101-1012:

In step 101, the interface tool 12 displays an operation interface of the interface tool 12.

Step 102, when receiving a first trigger operation of the freeze control on the operation interface, the interface tool 12 sends a freeze instruction to the control program 11 based on the first trigger operation; and generates a call indication to the function expansion interface.

Optionally, the function expansion interface of the first trigger operation instruction may be selected from a plurality of function expansion interfaces through an operation interface by a user; alternatively, the default setting in the interface tool 12 is not limited in this embodiment to the manner in which the first trigger operation triggers the invocation of the function extension interface.

Optionally, before the interface tool 12 generates the call instruction, it is further required to detect whether the current ultrasound scanning device 2 and the control program 11 are in an active state, and if so, generate the call instruction; if not, a step of detecting again whether the current ultrasound scanning apparatus 2 and the control program 11 are in an active state.

Wherein detecting whether the current ultrasound scanning apparatus 2 is in an active state comprises: the ultrasonic scanning equipment 2 sends a first heartbeat packet to the terminal 1 every a first preset period; if the interface tool 12 does not detect the first heartbeat packet in the first detection period, determining that the ultrasonic scanning device 2 is not in an active state; if the interface tool 12 detects the first heartbeat packet within the first detection period, it is determined that the ultrasound scanning device 2 is in an active state. The first detection period is greater than a first preset period.

Optionally, the first heartbeat packet carries a probe code read when the second control unit 222 is powered on.

Detecting whether the current control program 11 is in an active state includes: the control program 11 sends a second heartbeat packet to the second control unit 222 every a second preset period; if the interface tool 12 does not detect the second heartbeat packet in the second detection period, determining that the control program 11 is not in an active state; if the interface tool 12 detects the second heartbeat packet within the second detection period, it is determined that the ultrasound scanning device 2 is in an active state. The second detection period is greater than a second preset period.

Optionally, the second heartbeat packet carries the probe code sent by the second control unit 222.

The second detection period is the same as or different from the first detection period, and the second preset period is the same as or different from the first preset period.

Step 103, generating a second parameter control command through the function expansion interface; the second parameter control command is sent to the ultrasound scanning device 2 based on the wireless network 3.

The interface tool 12 is further configured to create a first command transmission channel port with the ultrasound scanning device 2 before transmitting the second parameter control command; the ultrasound scanning device 2 is also arranged to create a second command transmission channel opening with the interface tool 12, between which a first command channel is formed. At this time, the interface tool 12 is further configured to send a second parameter control command to the ultrasound scanning apparatus 2 via the first command channel based on the wireless network 3.

Optionally, the control program 11 is configured to send a first parameter control command to the ultrasound scanning device 2 via a second command channel with the ultrasound scanning device 2 based on the wireless network 3; while the interface tool 12 transmits the second parameter control command through the first command channel, transmission of the first parameter control command to the ultrasound scanning apparatus 2 through the second command channel is suspended. In other embodiments, while the interface tool 12 transmits the second parameter control command through the first command channel, the control program 11 may also continue to transmit the first parameter control command to the ultrasound scanning apparatus 2 through the second command channel.

At step 104, the control program 11, upon receiving the freeze instruction, transmits a suspension scanning instruction to the ultrasound scanning apparatus 2 based on the wireless network 3.

Step 105, when the ultrasonic scanning device 2 receives a scanning suspension instruction, controlling a probe in the ultrasonic scanning device 2 to stop scanning; and receives a second parameter control command.

At step 106, when receiving the second trigger operation for the freeze control, the interface tool 12 transmits a thawing instruction to the control program 11 based on the second trigger operation.

In step 107, the control program 11, upon receiving the defrosting instruction, transmits a resume scanning instruction to the ultrasound scanning apparatus 2 based on the wireless network 3.

At this point, the control program 11 continues to transmit the first parameter control command between the ultrasound scanning apparatus 2 using the second command channel.

In step 108, when the ultrasonic scanning device 2 receives the scanning restoration instruction, the probe in the ultrasonic scanning device 2 is controlled to continue scanning based on the second parameter control instruction.

Alternatively, the ultrasound scanning apparatus 2 stores the scanned data obtained by the scanning to the third storage unit 225.

Optionally, after step 107, the interface tool 12 may also generate a data acquisition command through the function expansion interface to acquire the corresponding target data. The target data is data acquired when the second parameter control command is executed. At this time, after step 107, steps 109-1012 are also included:

step 109, after the interface tool 12 generates the second parameter control command through the function expansion interface, if a first trigger operation of the freeze control in the operation interface of the interface tool 12 is received, sending a freeze instruction to the control program 11 based on the first trigger operation; and generates a data acquisition command based on the first trigger operation, and transmits the data acquisition command to the ultrasound scanning apparatus 2 based on the wireless network 3.

At step 1010, the control program 11, upon receiving the freeze instruction, transmits a suspension scan instruction to the ultrasound scanning apparatus 2 based on the wireless network 3.

In step 1011, the ultrasound scanning apparatus 2 transmits the target data to the function expansion interface upon receiving the suspension scanning instruction and the data acquisition command.

Illustratively, the interface tool 12 is also used to create a first data transmission channel port with the ultrasound scanning device 2; the ultrasound scanning device 2 is also used to create a second data transmission channel opening with the interface tool 12, between which a first data transmission channel is formed. At this time, the ultrasound scanning apparatus 2 is configured to transmit the target data to the expansion interface through the first data transmission channel.

In step 1012, the interface tool 12 receives the target data through the function expansion interface.

The type of the target data is determined based on the type indicated by the second parameter control command. Such as: the type indicated by the second parameter control command is an ADC type, and the ultrasonic scanning equipment 2 sends scanning data of the ADC type to the interface data; and, for example: the type indicated by the second parameter control command is an RF type, and the ultrasound scanning apparatus 2 transmits scanning data of the RF type to the interface data.

In one example, the extended function interface is described as including a data acquisition function interface:

The data acquisition function interface judges whether the current ultrasonic scanning equipment 2 and the control program 11 are in an active state; if yes, determining the type of data (ADC data or RF data) to be acquired; if not, continuing to wait. If the ADC data is acquired, at this time, a freeze instruction is sent to the control program 11 to stop the scanning by the ultrasonic scanning apparatus 2. Then, a first command transmission channel is created between the interface tool 12 and the second control unit 222, the interface tool 12 and the second control unit 222 are connected in a network, after the connection is successful, the interface tool 12 stops issuing a normal command through the second command transmission channel between the control program 11 and the second control unit 222, and sends a second control parameter command to the second control unit 222 through the first command transmission channel, wherein the second control parameter command indicates acquisition of ADC data; the second control unit 222 forwards the second control parameter command to the first control unit 221. After that, the interface tool 12 sends a defrosting instruction to the control program 11, so that the first control unit 221 starts to collect ADC data, stores the collected ADC data into the RF/ADC data space in the LPDDR4, and sends a freezing instruction to the control program 11 again after the ADC data with the corresponding byte length is collected, so that the ultrasound scanning apparatus 2 stops collecting ADC data. Thereafter, the interface tool 12 sends a data acquisition command to acquire ADC data; the second control unit 222, upon receiving the data acquisition command via the wireless network 3, transmits the ADC data of the required byte length to the interface means 12.

If the RF data is acquired, the acquisition flow is the same as the ADC data, but the ADC data is replaced by the RF data. Alternatively, the RF data may be acquired directly from the control program 11 after the freeze command is sent to the control program 11 for the first time. When the ADC or RF data is acquired by the interface tool 12, extended functionality of image data or post data analysis (or remote sharing) may be implemented.

In yet another example, the extended functionality interface is illustrated as including an online debug functionality interface:

the online debugging function interface judges whether the current ultrasonic scanning equipment 2 and the control program 11 are in an active state; if yes, a freezing instruction is sent to the control program 11 so that the ultrasonic scanning device 2 stops scanning; thereafter, a first command transmission channel is established between the interface tool 12 and the second control unit 222. Then, the interface tool 12 establishes a network connection with the second control unit 222, and pauses a second command transmission channel between the second control unit 222 and the control program 11; the interface tool 12 sends a second parameter control command indicating a parameter (e.g., a parameter table) that needs to be updated based on the first command transmission channel. After that, the interface tool 12 sends a defrosting instruction to the control program 11 to cause the ultrasound scanning apparatus 2 to start performing the scanning task, restoring the second command transmission channel. Thus, the expansion function of executing the corresponding image optimization work according to the actual needs can be realized.

In yet another example, the extended function interface is described as including a storage medium detection function interface:

the storage medium detection function interface judges whether the current ultrasonic scanning equipment 2 and the control program 11 are in an active state; if yes, a freeze instruction is sent to the control program 11 to stop the scanning by the ultrasonic scanning apparatus 2. Thereafter, a first command transmission channel is established between the interface tool 12 and the second control unit 222. Then, the interface tool 12 establishes a network connection with the second control unit 222, and pauses a second command transmission channel between the second control unit 222 and the control program 11; the interface tool 12 transmits a second parameter control command for indicating the DDR detection parameter and a check body for indicating check by the second control unit 222 or check by the interface tool 12 based on the first command transmission channel. After that, the interface tool 12 sends a defrosting instruction to the control program 11 to cause the ultrasound scanning apparatus 2 to start performing the scanning task, restoring the second command transmission channel. When the verification subject is the second control unit 222, a freeze instruction is again sent to the control program 11 to stop the scanning by the ultrasonic scanning apparatus 2. The interface tool 12 then sends a data acquisition command, and the second control unit 222 will transmit the result of the verification to the tool side via the network. When the verification subject is the interface tool 12, a freeze instruction is sent again to the control program 11 to stop the scanning by the ultrasonic scanning apparatus 2. The interface tool 12 then sends a data acquisition command, and the second control unit 222 transmits the DDR content to the interface tool 12 for the interface tool 12 to verify and store the data.

The operation flow of the other extended function interfaces is similar to the flow of the above 3 examples, and indicates that the content of the second parameter control command is different, which is not listed here.

In one example, after the first control unit 221 receives the resume scan instruction, the scan starts, at which time the FPGA (first control unit 221) parameter table command will write to the FPGA, the scan table command will write to the 0X2C000000 position of LPDDR4, the control program 11 will read the FPGA current state command, the control program 11 will read back the state being scanned, and the ARM (second control unit 222) will forward RF data or ADC data as needed according to the current scan state. The FPGA will put the acquired RF or ADC data at the base address of 0x2C400000 for LPDDR 4. The LPDDR4 memory allocation is shown in fig. 11. After the FPGA receives the scanning suspension instruction, the ARM can empty the RF/ADC data space in the LPDDR4, and the FPGA can empty the data FIFO.
