The non-scanning state refers to a state that the wireless ultrasonic probe is not in ultrasonic scanning operation. The scanning state refers to a state that the wireless ultrasonic probe is in ultrasonic scanning operation, and can be understood as a state that human tissues are scanned by ultrasonic waves.
As an example, the first control chip 1 is connected to the ultrasound scanning module 5 and the first communication module 3, the first control chip 1 can be powered on after the wireless ultrasound probe is started, when the wireless ultrasound probe is in a non-scanning state, that is, when the user does not control the wireless ultrasound probe to perform the ultrasound scanning operation on the human tissue, the power of the ultrasound scanning module 5 can be controlled, that is, the FPGA chip 51 in the ultrasound scanning module 5 and the front-end circuit 52 connected with the FPGA chip are controlled to be powered off, so as to achieve the purpose of saving power consumption; and the second control chip 2 and the second communication module 4 connected with the second control chip are controlled to be powered off, so that the purpose of saving power consumption is achieved; the first communication module 3 is also controlled to establish communication connection with the mobile terminal, so that the first control chip 1 can perform low-power data transmission with the mobile terminal through the first communication module 3, namely, the first control chip 1 can receive a control instruction sent by the mobile terminal through the first communication module 3, and the control instruction is used for controlling the power on and off of the ultrasonic scanning module 5, the second control chip 2 and the second communication module 4 so as to achieve the purpose of saving power consumption.
As an example, the second control chip 2 is connected to the ultrasonic scanning module 5 and the second communication module 4, where the second control chip 2 can receive a thawing instruction triggered by a user when the wireless ultrasonic probe is in a scanning state, and control the state of the wireless ultrasonic probe to perform ultrasonic scanning operation. The defrosting instruction can be an instruction formed by a control switch in the wireless ultrasonic probe operated by a user; the instruction triggered by the APP of the mobile terminal may also be transmitted to the first control chip 1 through the first communication module 3 and to the second control chip 2 through the first control chip 1. In this example, when the wireless ultrasonic probe is in the scanning state, the ultrasonic scanning module 5, the second control chip 2 and the second communication module 4 are all powered on to work, the second control chip 2 controls the ultrasonic scanning module 5 to perform scanning operation, ultrasonic image data is obtained, and the ultrasonic image data is sent to the mobile terminal through the second control chip 2 and the second communication module 4, so that the transmission efficiency of the ultrasonic image data is improved, and the requirement of real-time imaging is ensured.
In this embodiment, when the wireless ultrasonic probe is in a non-scanning state, the first control chip 1 controls the ultrasonic scanning module 5, the second control chip 2 and the second communication module 4 to be powered off so as to achieve the purpose of saving power consumption, and controls the first communication module 3 to establish communication with the mobile terminal, so that the first control chip 1 can communicate with the mobile terminal through the first communication module 3, and power consumption in the communication process can be saved; when the wireless ultrasonic probe is in a scanning state, the second control chip 2 controls the ultrasonic scanning module 5 to perform scanning operation, and ultrasonic image data is transmitted to the mobile terminal in real time through the second communication module 4, so that the transmission efficiency of the ultrasonic image data is improved, and the requirement of real-time imaging is ensured.
In an embodiment, as shown in fig. 2, the first control chip 1 is further configured to control the first communication module 3 to enter a pairing state after receiving a power-on instruction, and maintain the second control chip 2, the second communication module 4, and the ultrasound scanning module 5 powered off.
As an example, when the user operates the power-on key of the wireless ultrasonic probe, the first control chip 1 may receive a corresponding power-on instruction, so that the first control chip 1 is powered on; when the first control chip 1 is electrified and the second control chip 2, the first communication module 3, the second communication module 4 and the ultrasonic scanning module 5 are not electrified, the first communication module 3 can be controlled to be electrified, so that the first communication module 3 enters a pairing state, and the first communication module 3 is connected and paired with the mobile terminal; after the first communication module 3 enters the pairing state, the ultrasonic scanning module 5, the second control chip 2 and the second communication module 4 are required to be maintained in the power-off state, and whether the pairing is successful or not is detected in a first preset time, so that subsequent operation is executed according to the pairing result, the step-by-step power-up of the functional modules such as the ultrasonic scanning module 5, the second control chip 2 and the second communication module 4 is controlled, and a better control strategy is provided for the system power consumption through the grading function.
In an embodiment, the first control chip 1 is further configured to determine that the first communication module 3 and the mobile terminal establish communication connection after the first communication module 3 enters the pairing state, if the pairing is successful within a first preset time, so that the first communication module 3 enters the paired state; and if the wireless ultrasonic probe is not successfully paired in the first preset time, controlling the wireless ultrasonic probe to enter a low-power consumption state.
The first preset time is a preset time for evaluating whether the long time is in the pairing state. The low power consumption state of the wireless ultrasonic probe refers to a working state of the wireless ultrasonic probe with lower power consumption, and is specifically a state that other functional modules are powered off except for the first control chip and the interaction sensing module 6 connected with the first control chip, namely, the first communication module 3, the second control chip 2, the second communication module 4 and the ultrasonic scanning module 5 are powered off.
As an example, after the first control chip 1 is powered on, the first communication module 3 may be controlled to be powered on, so that the first communication module 3 enters a pairing state, and the first communication module 3 and the mobile terminal are connected and paired; after the first communication module 3 enters the pairing state, whether the pairing is successful is detected within a first preset time, so that the subsequent operation is executed according to the pairing result. If the pairing is detected to be successful in the first preset time, it can be determined that the first communication module 3 and the mobile terminal establish communication connection, that is, the first communication module 3 enters a paired state, so that the first control chip 1 can perform low-power data transmission, that is, non-ultrasonic image data transmission, with the mobile terminal through the first communication module 3, so that the first control chip 1 can receive a control instruction sent by the mobile terminal through the first communication module 3, and the ultrasonic scanning module 5, the second control chip 2 and the second communication module 4 are controlled to be powered on and powered off based on the control instruction, thereby achieving the purpose of saving power consumption. In this example, after determining that the first communication module 3 and the mobile terminal establish communication connection, it may be determined that the first communication module 3 enters a paired state, and at this time, the first control chip 1 and the first communication module 3 need to be kept powered on, and still keep controlling the second control chip 2, the second communication module 4 and the ultrasound scanning module 5 to be powered off, so as to achieve the purpose of saving power consumption. Correspondingly, if the pairing is unsuccessful within the first preset time, the wireless ultrasonic probe is controlled to enter a low-power consumption state, and at the moment, the first control chip 1 with lower power consumption and the interaction sensing module 6 connected with the first control chip 1 are electrified, so that the interaction sensing module 6 can interact with a user or perform state detection to determine whether the next state needs to be entered; correspondingly, the second control chip 2, the first communication module 3, the second communication module 4 and the ultrasonic scanning module 5 are powered off, so that the purpose of saving power consumption can be limited to the maximum.
In an embodiment, the first control chip 1 is further configured to control the second control chip 2, the second communication module 4, and the ultrasound scanning module 5 to be powered off when the wireless ultrasound probe is in a non-scanning state, and send target connection information corresponding to the second communication module 4 to the mobile terminal through the first communication module 3 after controlling the first communication module 3 to establish communication connection with the mobile terminal, so that the mobile terminal establishes communication connection with the second communication module 4 based on the target connection information.
The target connection information is information required for recording connection of the second communication module 4, and specifically includes, but is not limited to, information such as SSID, password, encryption mode, etc. of the second communication module 4, so that the APP of the mobile terminal can quickly establish communication with the second communication module 4 based on the target connection information.
As an example, when the wireless ultrasonic probe is in a non-scanning state, the first control chip 1 controls the ultrasonic scanning module 5, the second control chip 2 and the second communication module 4 to be powered off, and after the first communication module 3 is controlled to establish communication connection with the mobile terminal, the mobile terminal can also send target connection information corresponding to the second communication module 4, so that when the mobile terminal needs to communicate with the second communication module 4, the mobile terminal can directly establish communication connection with the second communication module 4 based on the target connection information, so that the communication connection between the two is simpler and more convenient, the communication connection time can be saved, the user experience can be improved, the power consumption in the information transmission process can be saved, and the standby time of the wireless ultrasonic probe can be effectively improved.
In an embodiment, as shown in fig. 2, the first control chip 1 is further configured to, after the first communication module 3 enters the paired state, send, by the first communication module 3, target connection information corresponding to the second communication module 4 to the mobile terminal if a thawing instruction triggered by a user operating the mobile terminal is received within a second preset time, so that the mobile terminal establishes communication connection with the second communication module 4 based on the target connection information; and if the thawing instruction triggered by the user operating the mobile terminal is not received within the second preset time, controlling the wireless ultrasonic probe to enter a low-power consumption state.
The second preset time is preset for evaluating whether the two pieces of equipment are in the paired state or not. The defrosting instruction refers to an instruction for controlling the wireless ultrasonic probe to switch from a non-scanning state to a scanning state so that the wireless ultrasonic probe can realize real-time scanning. Generally, after the wireless ultrasonic probe is powered on, the initial state is set to be a non-scanning state by default so as to achieve the purpose of saving power consumption, therefore, when the first communication module 3 enters the paired state, it can be determined that the wireless ultrasonic probe has established communication connection with the mobile terminal, so that the wireless ultrasonic probe can communicate with the mobile terminal through the first communication module 3 to transmit a defrosting instruction, and the wireless ultrasonic probe can be switched from the non-scanning state to the scanning state.
As an example, after the first control chip 1 is powered on and controls the first communication module 3 to be successfully paired with the mobile terminal, that is, when the first communication module 3 is determined to enter the paired state, it may be determined that the first communication module 3 and the mobile terminal are in communication connection, and at this time, whether to receive a thawing instruction triggered by the APP that operates the mobile terminal by the user needs to be detected within a second preset time; if a thawing instruction triggered by a user is received in the second preset time, it may be determined that the user wants to operate the APP thawing wireless ultrasonic probe so that the APP thawing wireless ultrasonic probe can be scanned in real time, at this time, the target connection information corresponding to the second communication module 4 may be sent to the mobile terminal through a communication link between the first communication module 3 and the mobile terminal, so that when the mobile terminal needs to communicate with the second communication module 4, communication connection may be directly established between the mobile terminal and the second communication module 4 based on the target connection information, so that communication connection between the mobile terminal and the second communication module 4 is simpler and more convenient, communication connection time may be saved, user experience may be improved, and the target connection information is transmitted through the first communication module 3, power consumption in an information transmission process may be saved, and standby time of the wireless ultrasonic probe may be effectively improved. Correspondingly, if the thawing instruction triggered by the user is not received within the second preset time, it can be determined that the user does not want to operate the APP thawing wireless ultrasonic probe, that is, the real-time scanning function of the wireless ultrasonic probe needs to be frozen, the wireless ultrasonic probe needs to be controlled to enter a low-power-consumption state, so that the second control chip 2, the second communication module 4 and the ultrasonic scanning module 5 are powered off, and the first control chip 1 with lower power consumption and the interaction sensing module 6 connected with the first control chip 1 are powered on, so that the interaction sensing module 6 can interact with the user or perform state detection to determine whether the next state needs to be entered, and the purpose of saving power consumption is achieved.
In an embodiment, the first control chip 1 is further configured to obtain a terminal attribute of the mobile terminal when the wireless ultrasound probe is in a scanning state and receives a freeze instruction triggered by a user operating the mobile terminal; if the terminal attribute is that the second communication module 4 is supported to be automatically connected, the ultrasonic scanning module 5, the second control chip 2 and the second communication module 4 are controlled to be powered off; if the terminal attribute is that the second communication module 4 is not supported to be automatically connected, the ultrasonic scanning module 5 is controlled to be powered off, and the second communication module 4 is controlled to enter a low-power consumption mode through the second control chip 2, so that the connection with the mobile terminal is maintained.
The freezing instruction refers to an instruction for controlling the wireless ultrasonic probe to be switched from a scanning state to a non-scanning state so that the wireless ultrasonic probe does not perform real-time scanning.
As an example, when the wireless ultrasound probe is in the scanning state, the first communication module 3 is in communication connection with the mobile terminal, and can receive a freeze instruction triggered by the user operating the mobile terminal, so that the wireless ultrasound probe finishes the scanning operation, and at this time, the first control chip 1 needs to communicate with the mobile terminal through the first communication module 3 to determine the terminal attribute of the mobile terminal. When the terminal attribute is that the second communication module 4 is supported to be automatically connected, the ultrasonic scanning module 5, the second control chip 2 and the second communication module 4 can be controlled to be powered off, and at the moment, only the first control chip 1 and the first communication module 3 connected with the first control chip are kept to be powered on so as to achieve the purpose of saving power consumption; correspondingly, when the first control chip 1 receives the defrosting instruction again, the mobile terminal supports the second communication module 4 to be automatically connected, so that the mobile terminal can be quickly connected with the second communication module 4 without induction or slight intervention of a user, and the real-time transmission of the ultrasonic image data is recovered, so that the optimal standby time is reached. When the terminal attribute is that the second communication module 4 is not supported to be automatically connected, the ultrasonic scanning module 5 can be controlled to be powered off, the second communication module 4 is controlled to enter a low-power consumption mode through the second control chip 2, the terminal is connected with the mobile terminal, and accordingly, when the first control chip 1 receives a defrosting instruction again, the real-time transmission of ultrasonic image data can be directly carried out, so that the purpose of saving power consumption is achieved. In this example, the second communication module 4 entering the low power consumption mode refers to a mode in which the second communication module 4 remains connected to the mobile terminal, but the operation power consumption is low, and the real-time transmission of the ultrasound image data is not supported. Understandably, when the terminal attribute does not support the automatic connection of the second communication module 4, and when the wireless ultrasonic probe is in a scanning state and receives a freezing instruction, if the second communication module 4 is controlled to be powered off, the process of powering on the second communication module and establishing connection with the mobile terminal needs to be repeated, so that the time consumption is long; if the second communication module 4 is controlled to still maintain the scanning power consumption in the scanning state, the power consumption is larger; therefore, when the ultrasonic scanning module is controlled to be powered off when the freezing instruction is received in the scanning state, the second communication module 4 is controlled to enter the low-power mode through the second control chip to be connected with the mobile terminal, so that the time for establishing connection with the mobile terminal next time can be saved, and the power consumption can be reduced.
In one embodiment, as shown in fig. 2, the wireless ultrasonic probe further comprises an interaction sensing module 6 connected with the first control chip 1; the first control chip 1 is further configured to control the interaction sensing module 6 to work after the wireless ultrasonic probe enters a low power consumption state, and if an interaction sensing signal triggered by the interaction sensing module 6 is received within a third preset time, control the first communication module 3 to enter a pairing state; and if the interaction sensing signal triggered by the interaction sensing module 6 is not received within the third preset time, controlling the wireless ultrasonic probe to be powered off.
The interaction sensing module 6 is a module which is arranged on the wireless ultrasonic probe and used for realizing man-machine interaction or sensing. The third preset time is a time preset for evaluating whether or not the longer time is in the low power consumption state.
As an example, after the first control chip 1 enters the low power consumption state, the ultrasonic scanning module 5, the first communication module 3, the second control chip 2 and the second communication module 4 are required to be controlled to be powered off, only the first control chip 1 and the interaction sensing module 6 with low power consumption are kept to be powered on, the interaction sensing module 6 is controlled to work, and whether an interaction sensing signal triggered by the interaction sensing module 6 is received within a third preset time for entering the low power consumption state is judged. If the interaction sensing signal is received within the third preset time, the user is further indicated to operate the wireless ultrasonic probe, at this time, the condition of triggering to exit the low power consumption state can be determined to be met, at this time, the first communication module 3 needs to be controlled to enter the pairing state, so that the first communication module 3 is in communication connection with the mobile terminal and performs subsequent operations. Correspondingly, if the interaction induction signal is not received within the third preset time, the fact that the user does not further operate the wireless ultrasonic probe is indicated, and the condition that the low-power-consumption state is triggered to exit is determined to be unsatisfied, at this time, the first control chip 1 is in the low-power-consumption state within a longer time, and it can be determined that the user cannot use the wireless ultrasonic probe temporarily, so that the wireless ultrasonic probe can be controlled to be turned off, and the purpose of saving power consumption is achieved.
In one embodiment, as shown in fig. 1, the interaction sensing module 6 includes a switch key 61, an NFC module 62, and an attitude sensor 63.
As an example, the interaction sensing module 6 may include a switch key 61, an NFC module 62 and a gesture sensor 63, where after the first control chip 1 is connected to the low power consumption state, that is, when the first control chip 1 and the interaction sensing module 6 are powered on and all other functional modules are powered off, if any one of an interaction sensing signal triggered by the user operating the switch key 61, an interaction sensing signal triggered by the NFC module 62 and an interaction sensing signal triggered by the gesture sensor 63 sensing movement of the user operating the wireless ultrasonic probe is received within a third preset time, it is indicated that the user further operates the wireless ultrasonic probe, and the condition of exiting the low power consumption state is satisfied, at this time, the first control chip 1 needs to be made to exit the low power consumption state, and at this time, the first communication module 3 connected to the first control chip 1 is controlled to operate so that the first communication module 3 enters the pairing state and is connected to the mobile terminal in communication; if the interaction sensing signal triggered by the user operating the switch key 61 is not received within the third preset time, the interaction sensing signal triggered by the NFC module 62 is not received, and the interaction sensing signal triggered by the gesture sensor 63 to sense the movement of the wireless ultrasonic probe is not received, which indicates that the first control chip 1 is in a low power consumption state for a long time, it can be determined that the user cannot use the wireless ultrasonic probe temporarily, so that the wireless ultrasonic probe can be controlled to be turned off, and the purpose of saving power consumption is achieved.

After the Bluetooth module is in the paired state, if a thawing instruction triggered by a user operating the mobile terminal is received within a second preset time, the first control chip 1 sends target connection information (including SSID, password, encryption mode and the like) corresponding to the WiFi module to the mobile terminal through the Bluetooth module, so that when the follow-up requirement is scanned in real time, the mobile terminal can establish communication connection with the WiFi module based on the target connection information, the connection process of the mobile terminal and the WiFi module is simple and convenient, the mobile terminal can be quickly connected under the condition that the user does not feel or slightly intervenes, and the connection efficiency is improved.

When the mobile terminal does not support the automatic connection of the WiFi module, the ultrasonic scanning module 5 can be controlled to be powered off, and the WiFi module is controlled to be connected with the mobile terminal through the second control chip 2, so that when the wireless ultrasonic probe enters the scanning state again, the real-time transmission of ultrasonic image data can be directly carried out, and the purpose of saving power consumption is achieved.
After the first control chip 1 is connected into a low-power consumption state, the first control chip 1 and the interaction sensing module 6 connected with the first control chip 1 are required to be controlled to be powered on, and other functional modules are powered off, namely the second control chip 2, the Bluetooth module, the WiFi module and the ultrasonic scanning module 5 are powered off, so that the purpose of saving power consumption is achieved; after entering a low power consumption state, the interaction sensing signal triggered by the interaction sensing module 6 can be monitored within a third preset time; if any one of the switch key 61, the NFC module 62 and the gesture sensor 63 triggers an interaction sensing signal within a third preset time, the user is further instructed to operate the wireless ultrasonic probe, and at this time, the bluetooth module connected to the first control chip 1 is controlled to work, so that the bluetooth module enters a pairing state, and is in communication connection with the mobile terminal, so as to be controlled by transmitting a control instruction through the bluetooth module subsequently; if the interaction sensing signal triggered by the switch key 61, the NFC module 62 and the gesture sensor 63 is not received within the third preset time, it is indicated that the first control chip 1 is in a low power consumption state for a long time, and it can be determined that the user cannot use the wireless ultrasonic probe temporarily, so that the wireless ultrasonic probe can be controlled to be turned off, and the purpose of saving power consumption is achieved.

As an example, the first control chip 1 communicates with the mobile terminal through the first communication module 3, and may receive a thawing instruction triggered by the mobile terminal, so as to control the ultrasound scanning module 5 to be powered on based on the thawing instruction, so as to perform ultrasound scanning. The second control chip 2 is communicated with the mobile terminal through the second communication module 4, and can receive a thawing instruction triggered by the mobile terminal so as to control the ultrasonic scanning module 5 to be electrified based on the thawing instruction so as to carry out ultrasonic scanning.
