In the following description, many specific details are explained in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

It should be noted that when an element is referred to as being "disposed on" another element, it can be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only, and are not meant to be the only embodiments.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of the present invention. The terminology used in the specification of the present invention herein is only for the purpose of describing specific embodiments, and is not intended to limit the present invention.

Please refer to FIG. 1. An embodiment of the present application provides a temperature control method of an ultrasonic system, which includes the following steps:

S100: Detect the state of the input device of the ultrasound system to determine whether the ultrasound system is in an idle state or a working state.

In this embodiment, the input device is a device for information interaction between the user and the ultrasound system. If the input device is working, it represents that the ultrasound system is in a working state, and if the input device is not working, it represents that the ultrasound system is in an idle state.

S200: When the ultrasonic system is in working state, detect the temperature of the ultrasonic system and adjust the fan's gear according to the pre-stored temperature-gear relationship.

The ultrasound system includes a temperature detection device for real-time detection of the temperature of the ultrasound system. When the ultrasonic system is in working state, the fan's gear is adjusted according to the detected temperature and the pre-stored temperature-gear relationship. The fan gear is positively correlated with the fan speed, that is, the higher the gear, the higher the speed and the stronger the heat dissipation capacity. In this embodiment, when the detected temperature is higher, the corresponding fan gear is also higher, that is, the temperature is positively correlated with the gear.

S300: When the ultrasound system is in an idle state, detect the temperature of the ultrasound system and determine whether the temperature is greater than or equal to a preset temperature.

When the input device is not working and the ultrasound device is in an idle state, the ultrasound system first determines whether the received temperature is greater than or equal to the preset temperature to determine whether the heat dissipation needs to be turned on.

S400: If the temperature of the ultrasonic system is greater than or equal to the preset temperature, adjust the fan to the highest gear.

If the temperature of the ultrasound system is greater than or equal to the preset temperature, and heat dissipation needs to be turned on, adjust the fan to the highest gear to make the fan run at the maximum speed to quickly dissipate heat when the ultrasound system is idle. Furthermore, the ultrasound system can enter the working state from the idle state at a lower temperature every time.

If the temperature of the ultrasound system is lower than the preset temperature, there is no need to turn on the heat dissipation, and there is no need to turn on the fan.

The temperature control method of the ultrasound system provided in the above embodiment judges whether the ultrasound system is in an idle state by detecting the state of the input device. When the ultrasound system is in the idle state, the fan is adjusted to the highest gear to make the fan dissipate heat at the maximum speed, so that it can be used The idle state of the ultrasonic equipment cools down at full speed to ensure that the ultrasonic equipment enters the working state from the idle state at a lower temperature every time, which improves the system stability and the service life of the hardware. In addition, by cooling the temperature at full speed in the idle state, and controlling the operation of the fan according to the temperature-gear correspondence relationship in the working state, the noise generated by the ultrasonic system in the working state can be reduced.

In one of the embodiments, the input device of the ultrasound system includes a keyboard, a touch screen, and at least one ultrasound probe. The ultrasound system also includes a main control device, which includes an upper computer and a control module. The host computer is connected to the keyboard and the touch screen, and can judge whether the keyboard or the touch screen is in an idle state or working state by detecting whether it receives an input signal from the keyboard or the touch screen. The control module is connected to each ultrasonic probe, and is used to detect whether each ultrasonic probe is on the probe hanger to determine whether the ultrasonic probe is in a working state or an idle state. Referring to FIG. 2, in this embodiment, detecting the state of the input device of the ultrasound system to determine whether the ultrasound system is in an idle state or working state specifically includes the following steps:

S110: When the ultrasound system is powered on, first check whether each ultrasound probe is in an idle state.

When the ultrasound system is powered on, the ultrasound system enters the working state by default. At this time, the control device first detects whether each ultrasound probe is in an idle state, that is, whether each ultrasound probe is set on the probe hanger. If each ultrasound probe is located on the probe hanger, each ultrasound probe is in an idle state, and if at least one ultrasound probe leaves the hanger, at least one ultrasound probe is in a working state.

S120: If each ultrasound probe is in an idle state, detect the state of each ultrasound probe, keyboard and touch screen within a preset time interval.

If each ultrasound probe is in an idle state, indicating that no ultrasound probe is in use, the timer of the ultrasound system starts timing. The timer is set with a preset time interval, and the host computer and the control module detect the state of the keyboard, touch screen and each ultrasound probe within the preset time interval to determine whether the ultrasound system enters an idle state.

S130: If the keyboard, the touch screen, and each ultrasound probe are in an idle state within the preset time interval, the ultrasound system is in an idle state.

In the preset time interval, if the upper computer does not detect the input signal of the keyboard and touch screen, and the control module detects that each ultrasound probe is located on the probe hanger, the keyboard, touch screen and each ultrasound probe are in an idle state. That is, the ultrasound system enters an idle state. The host computer adjusts the fan to the highest position, so that the fan cools down at full speed during the idle time of the ultrasonic system.

S140: If the keyboard or the touch screen is in the working state within the preset time interval, or at least one ultrasound probe is in the working state, the ultrasound system is in the working state.

If within the preset time interval, the upper computer detects the input signal of the keyboard or touch screen, that is, the keyboard or touch screen is in working state, or the control module detects that at least one ultrasound probe has left the probe hanger, that is, at least one ultrasound probe is in Working state, the ultrasound system is in working state. At this time, the host computer controls the fan according to the received temperature of the ultrasonic system to adjust the fan's gear according to the pre-stored temperature-gear relationship.

Further, if during the timing period, the control module detects that at least one ultrasound probe has left the probe hanger, the timer is cleared and kept at zero until the control module detects that each ultrasound probe is located on the probe hanger. Restart timing.

If during the timing period, each ultrasound probe is located on the probe hanger, but the upper computer detects the input signal of the touch screen or keyboard, the timer will be cleared and timed again. If the preset time is reached after re-timing, it indicates that the system is in an idle state during the timing period.

In one of the embodiments, the temperature-gear position relationship includes the corresponding relationship between the threshold value and the gear position.

Specifically, the fan is provided with a first gear position, a second gear position, and a third gear position, and the fan speeds corresponding to the first gear position, the second gear position and the third gear position are sequentially increased. The first, second, and third thresholds corresponding to the first, second, and third gears are pre-stored in the host computer. The temperature corresponding to the limit value and the third threshold value increases sequentially. When the ultrasound system is in the working state, the host computer receives the temperature of the ultrasound system and judges the relationship between the temperature and the first threshold value, the second threshold value, and the third threshold value. When the temperature is greater than or equal to the first threshold value and less than the second threshold value, the upper computer controls the fan to work in the first gear. When the temperature is greater than or equal to the second threshold value and less than the third threshold value, the upper computer controls the fan to work in the second gear. When the temperature is greater than or equal to the third threshold, the host computer controls the fan to work in the third gear. When the temperature is less than the first threshold value, it indicates that the temperature of the ultrasound system is low and heat dissipation is not required.

If the ultrasound system is in an idle state, the host computer judges the temperature of the ultrasound system and the first threshold value. If it is greater than or equal to the first threshold value, it controls the fan to cool down at full speed according to the third gear until the temperature of the ultrasound system is less than Preset the temperature and maintain the preset time interval, and then run the fan in the first gear, so that the ultrasonic system quickly dissipates heat in the idle state, so that it can enter the working state at a lower temperature. The preset temperature may be the temperature corresponding to the first threshold value. Of course, the range of the fan gear and the temperature threshold in the host computer can be multiple, which can be set according to user needs.

The method provided by the above embodiment judges whether the ultrasound system is in an idle state by detecting the state of the input device. When the ultrasound system is in the idle state, adjust the fan to the highest gear to make the fan dissipate heat at the maximum speed, so that the idle state of the ultrasound device can be used The gap is cooled at full speed to ensure that the ultrasonic equipment enters the working state from the idle state at a lower temperature every time, improving the system stability and the service life of the hardware. In addition, by cooling the temperature at full speed in the idle state, and controlling the operation of the fan according to the temperature-gear correspondence relationship in the working state, the noise generated by the ultrasonic system in the working state can be reduced.
