Referring to fig. 1, fig. 1 is a schematic structural diagram of a detection mode control circuit according to an embodiment of the present invention.
As shown in fig. 1, a detection mode control circuit includes: a composite probe 300, and a parameter detection control circuit 100 and an imaging control circuit 200 respectively connected to the composite probe 300, wherein: the parameter detection control circuit 100 is configured to control the composite probe 300 to perform parameter detection according to a control signal input by a user; the imaging control circuit 200 is configured to control the composite probe 300 to perform imaging according to a control signal input by a user; the control signal is used to control the composite probe 300 to be conducted with the parameter detection control circuit 100 or the imaging control circuit 200.
Specifically, the composite probe 300 is capable of parameter detection and imaging; the parameter detection control circuit 100 is connected to the composite probe 300, and is configured to receive a control signal input by a user, and control the composite probe 300 to complete parameter detection based on the control signal; the imaging control circuit 200 and the composite probe 300 are configured to receive a control signal input by a user, and control the composite probe 300 or complete imaging based on the control signal; the control signal is used to control the composite probe 300 to be conducted with the parameter detection control circuit 100 or the imaging control circuit 200.

The parameter detection comprises the following steps: elastic parameter detection and viscosity parameter detection. The composite probe 300 may be provided in plurality. Wherein the parameter detection control signal includes: the parameter detection ultrasonic wave generation signal and the pressure sensing signal. When the composite probe 300 receives the parameter detection ultrasonic wave generation signal and the pressure sensing signal, firstly, the pressure between the composite probe 300 and a substance to be detected is collected, and when the collected pressure value is greater than the pressure value of the pressure sensing signal, the parameter detection ultrasonic wave generation signal controls the composite probe 300 to generate the parameter detection ultrasonic wave to complete parameter detection; when the collected pressure value is less than or equal to the pressure value of the pressure sensing signal, the composite probe 300 does not work.

The imaging control signal includes: the imaging ultrasound generates a signal. The imaging ultrasonic wave generation signal controls the composite probe 300 to generate the imaging ultrasonic wave to complete imaging. Because the control signal input by the user at the same time can only be generated by the parameter detection control circuit or the imaging control circuit, the parameter detection control circuit 100 is not conducted when imaging detection signal is generated; when the parameter detection signal is generated, the parameter detection is performed, and the imaging control circuit 200 is not turned on. I.e., to ensure that the composite probe 300 can only be in one test mode at a time.
Preferably, the parameter detection control module includes: a parameter detection signal generation circuit 110 and a first switch circuit 120; a parameter detection signal generation circuit 110, connected to the first switch circuit 120, for receiving a control signal input by a user, generating a parameter detection control signal, a first control signal, a second control signal, a third control signal, and a fourth control signal based on the control signal, and transmitting the parameter detection control signal, the first control signal, the second control signal, the third control signal, and the fourth control signal to the first switch circuit 120; the first switch circuit 120 is connected to the composite probe 300, and is configured to control the switches to be turned on or off according to the first control signal, the second control signal, the third control signal, and the fourth control signal, and transmit the parameter detection control signal to the composite probe 300 based on the turned-on high-voltage electronic switches.

Specifically, the switch control circuit 220 includes three input interfaces and four output interfaces, wherein the three input interfaces are connected to the imaging signal generation circuit 210, and receive the fifth control signal, the sixth control signal and the seventh control signal generated by the imaging signal generation circuit 210. The switch control circuit 220 generates a second switch control signal according to the received fifth control signal, sixth control signal and seventh control signal.

When the seventh control signal is at a high level, the second switch control signal is four high level signals output by the four output interfaces, and the four high level signals control the four switches in the second switch circuit 230 to be turned off. When the seventh control signal is at a low level, the sixth control signal is at a low level, and the fifth control signal is at a low level, the second switch control signal is that the first output interface of the four output interfaces outputs a low level, and the other three output interfaces output a high level; when the seventh control signal is at a low level, the sixth control signal is at a low level, and the fifth control signal is at a high level, the second switch control signal is that the second output interface of the four output interfaces outputs a low level, and the other three output interfaces output high levels; when the seventh control signal is at a low level, the sixth control signal is at a high level, and the fifth control signal is at a low level, the second switch control signal is that the third output interface of the four output interfaces outputs a low level, and the other three output interfaces output a high level; when the seventh control signal is at a low level, the sixth control signal is at a high level, and the fifth control signal is at a high level, the second switch control signal is at a low level output by the fourth output interface of the four output interfaces, and at a high level output by the remaining three output interfaces. Wherein the low level control switch is turned on and the high level control switch is turned off. The second switch circuit 230 includes four switches, and the four switches include four switch input interfaces, four switch output interfaces, and four control interfaces, wherein the four control interfaces are respectively connected with the four output interfaces of the switch control circuit 220, and the four switches are controlled to be turned on or off by the second switch control signals output by the four output interfaces of the switch control circuit 220.

Only one of the composite probes 300 can be in the imaging detection mode at a time.
Preferably, the first control signal and the seventh control signal have opposite phases. When a user inputs a control signal to perform parameter detection, the first control signal CLR is at a low level, the first switch circuit 120 controls the 16 switches to turn on the composite probe 300 for parameter detection according to the fourth control signal DIN, at this time, the seventh control signal is at a high level, the second switch control signals are four high level signals output by the four output interfaces, and the four high level signals control the four switches in the second switch circuit 230 to turn off. When a user inputs a control signal for imaging, and the first control signal CLR is at a high level, all 16 switches of the first switch circuit 120 are turned off; the seventh control signal is at a low level, and the second switch control signal controls one of the four switches of the fourth control second switch circuit 230 to be turned on, that is, one of the composite probes 300 performs imaging. Therefore, it can be ensured that the second switch circuit 230 is in the off state while the first switch circuit 120 is in the on state; when the first switch circuit 120 is in the off state, the second switch circuit 230 is in the on state. That is to say, the composite probe 300 can only be in the imaging detection state or the parameter detection state at the same time, and the imaging control module and the parameter detection control module do not interfere with each other, so as to avoid the problem of signal interference caused by simultaneous signal conduction. Only one of the multiple composite probes 300 can be in the imaging detection mode at a time.
