Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
It will be understood that when an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Referring to fig. 1, an embodiment of the present application provides a temperature control method for an ultrasound system, including the following steps:
s100: the status of an input device of the ultrasound system is detected to determine whether the ultrasound system is in an idle state or an operational state.
In this embodiment, the input device is a device for performing information interaction between a user and the ultrasound system, and 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 a working state, the temperature of the ultrasonic system is detected, and the gear of the fan is adjusted according to the pre-stored temperature-gear relation.
The ultrasound system includes a temperature detection device for detecting the temperature of the ultrasound system in real time. When the ultrasonic system is in a working state, the gear of the fan is adjusted according to the detected temperature and the pre-stored temperature-gear relation. The gear of the fan is positively correlated with the rotating speed of the fan, namely the higher the gear is, the larger the rotating speed is, and the stronger the heat dissipation capacity is. 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 ultrasonic system is in an idle state, the temperature of the ultrasonic system is detected and whether the temperature is greater than or equal to a preset temperature is judged.
When the input device is not in operation, the ultrasonic device is in an idle state, and the ultrasonic system firstly judges whether the received temperature is greater than or equal to a preset temperature so as to judge whether heat dissipation needs to be started.
S400: and if the temperature of the ultrasonic system is greater than or equal to the preset temperature, adjusting the fan to the highest gear.
If the temperature of the ultrasonic system is greater than or equal to the preset temperature and heat dissipation needs to be started, the fan is adjusted to the highest gear, so that the fan runs at the maximum rotating speed, and heat dissipation is performed quickly when the ultrasonic system is in an idle state. And the ultrasound system can enter the operating state from the idle state at a lower temperature each time.
If the temperature of the ultrasonic system is lower than the preset temperature, the heat dissipation does not need to be started, and a fan does not need to be started.
The temperature control method of the ultrasonic system provided by the embodiment judges whether the ultrasonic system is in the idle state by detecting the state of the input device, and adjusts the fan to the highest gear when the ultrasonic system is in the idle state, so that the fan radiates heat at the maximum rotating speed, thereby the idle state gap of the ultrasonic device can be utilized to cool at full speed, the ultrasonic device is ensured to enter the working state from the idle state at a lower temperature every time, and the stability of the system and the service life of hardware are improved. In addition, the temperature is reduced at full speed in the idle state, and the fan is controlled to operate according to the temperature-gear corresponding relation in the working state, so that the noise generated by the ultrasonic system in the working state can be reduced.
In one embodiment, the input devices of the ultrasound system include a keyboard, a touch screen, and at least one ultrasound probe. The ultrasonic system also comprises a main control device, and the main control device comprises an upper computer and a control module. The upper computer is connected with the keyboard and the touch screen, and can judge whether the keyboard or the touch screen is in an idle state or a working state by detecting whether an input signal of the keyboard or the touch screen is received or not. The control module is connected with each ultrasonic probe and used for detecting whether each ultrasonic probe is positioned on the probe hanging rack or not and judging whether the ultrasonic probe is in a working state or an idle state or not. Referring to fig. 2, in the present embodiment, detecting the state of the input device of the ultrasound system to determine whether the ultrasound system is in the idle state or the working state specifically includes the following steps:
s110: when the ultrasonic system is powered on, whether each ultrasonic probe is in an idle state is detected.
When the ultrasound system is powered on, the ultrasound system enters a working state by default. At the moment, the control device firstly detects whether each ultrasonic probe is in an idle state, namely whether each ultrasonic probe is arranged on the probe hanging frame. If each ultrasonic probe is positioned on the probe hanging rack, each ultrasonic probe is in an idle state, and if at least one ultrasonic probe leaves the hanging rack, at least one ultrasonic probe is in a working state.
S120: and if each ultrasonic probe is in an idle state, detecting the state of each ultrasonic probe, the keyboard and the touch screen within a preset time interval.
If each ultrasonic probe is in an idle state, which indicates that no ultrasonic probe is in use, the timer of the ultrasonic system starts to time. The timer is set with a preset time interval, and the upper computer and the control module detect the states of the keyboard, the touch screen and each ultrasonic probe in the preset time interval and judge whether the ultrasonic system enters an idle state or not.
S130: and if the keyboard, the touch screen and each ultrasonic probe are in the idle state within the preset time interval, the ultrasonic system is in the idle state.
In a preset time interval, the upper computer does not detect input signals of the keyboard and the touch screen, and the control module detects that each ultrasonic probe is located on the probe hanging rack, so that the keyboard, the touch screen and each ultrasonic probe are in an idle state, namely the ultrasonic system enters the idle state. And the upper computer adjusts the fan to the highest gear so that the fan is cooled at full speed in the idle time of the ultrasonic system.
S140: if the keyboard or the touch screen is in a working state or at least one ultrasonic probe is in a working state within a preset time interval, the ultrasonic system is in a working state.
If the upper computer detects an input signal of the keyboard or the touch screen within a preset time interval, namely the keyboard or the touch screen is in a working state, or the control module detects that at least one ultrasonic probe leaves the probe hanging frame, namely the at least one ultrasonic probe is in the working state, the ultrasonic system is in the working state. At the moment, the upper computer controls the fan to adjust the gear of the fan according to the received temperature of the ultrasonic system and the pre-stored temperature-gear relation.
Further, if the control module detects that at least one ultrasonic probe leaves the probe rack within the timing period, the timer is reset and kept to be zero until the control module detects that each ultrasonic probe is located on the probe rack, and the timer restarts to count.
If each ultrasonic probe is positioned on the probe hanging frame in the timing period, but the upper computer detects an input signal of the touch screen or the keyboard, the timer is used for timing, resetting and re-timing. If the preset time is reached after the timing is restarted, the system is in an idle state in the timing period.
In one embodiment, the temperature-gear relationship includes a correspondence between threshold values and gears.
Specifically, the fan is provided with a first gear, a second gear and a third gear, and the rotating speeds of the fan corresponding to the first gear, the second gear and the third gear are sequentially increased. A first threshold value, a second threshold value and a third threshold value which are respectively corresponding to the first gear, the second gear and the third gear are prestored in the upper computer, and the temperatures corresponding to the first threshold value, the second threshold value and the third threshold value are sequentially increased. When the ultrasonic system is in a working state, the upper computer receives the temperature of the ultrasonic system and judges the size relationship between the temperature and the first threshold value, the second threshold value and the third threshold value. When the temperature is larger than or equal to the first threshold value and smaller than the second threshold value, the upper computer controls the fan to work according to the first gear. And 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 according to the second gear. And when the temperature is greater than or equal to a third threshold value, the upper computer controls the fan to work according to a third gear. When the temperature is lower than the first threshold value, the temperature of the ultrasonic system is low, and heat dissipation can be omitted.
If the ultrasonic system is in an idle state, the upper computer judges the temperature of the ultrasonic system and the first threshold value, if the temperature of the ultrasonic system is larger than or equal to the first threshold value, the fan is controlled to carry out full-speed cooling according to the third gear until the temperature of the ultrasonic system is smaller than the preset temperature and keeps the preset time interval, and then the fan is operated at the first gear, so that the ultrasonic system can rapidly dissipate heat in the idle state, and can enter a working state at a lower temperature. The preset temperature may be a temperature corresponding to the first threshold. Of course, the range of the gear of the fan and the temperature threshold value in the upper computer can be multiple, and can be set according to the requirement of a user.
The method provided by the embodiment judges whether the ultrasonic system is in the idle state or not by detecting the state of the input device, and adjusts the fan to the highest gear when the ultrasonic system is in the idle state, so that the fan radiates heat at the maximum rotating speed, the idle state gap of the ultrasonic device can be utilized for full-speed cooling, the ultrasonic device is ensured to enter the working state from the idle state at a lower temperature every time, and the system stability and the service life of hardware are improved. In addition, the temperature is reduced at full speed in the idle state, and the fan is controlled to operate according to the temperature-gear corresponding relation in the working state, so that the noise generated by the ultrasonic system in the working state can be reduced.
Referring to fig. 3, another embodiment of the present application provides an ultrasound system including a main control device 100 and a fan 200. The main control device 100 is used for detecting the state of the input device 300 of the ultrasound system to determine whether the ultrasound system is in a contributing state or an operating state. The fan 200 is connected to the main control device 100, and when the ultrasound system is in a working state, the main control device 100 adjusts the gear of the fan 200 according to the temperature of the ultrasound system and a pre-stored temperature-gear relationship. If the ultrasound system is in an idle state, the main control device 100 determines whether the temperature of the ultrasound system is greater than or equal to a preset temperature, and when the temperature of the ultrasound system is greater than or equal to the preset temperature, the main control device 100 adjusts the fan 200 to a highest gear, so that the fan 200 dissipates heat at a maximum rotation speed.
In the above embodiment, the main control device 100 includes an upper computer 110 and a control module 120. The upper computer 110 may be a Central Processing Unit (CPU), and the control module 120 may be a Field Programmable Gate Array (FPGA). The input device 300 includes a keypad 310, a touch screen 320, and at least one ultrasound probe 330. The upper computer 110 is connected with the keyboard 310 and the touch screen 320, and can judge the state of the keyboard 310 or the touch screen 320 by detecting whether an input signal of the keyboard 310 or the touch screen 320 is received. The control module 120 is connected to each ultrasonic probe 330, and is configured to detect whether each ultrasonic probe 330 is on the probe rack, and determine whether the ultrasonic probe 330 is in a working state or an idle state. The control module 120 is connected to the upper computer 110, and is configured to send the detected state of the ultrasonic probe 330 to the upper computer 110, so that the upper computer 110 determines the state of the ultrasonic system and controls the fan 200 to operate.
The ultrasound system further comprises a timer 400 for a preset time interval. The timer 400 is connected to the upper computer 110, and is configured to receive a control instruction of the upper computer 110. When the ultrasound system is powered on, the control module 120 first detects whether each ultrasound probe 330 is in an idle state, and when each ultrasound probe 330 is in the idle state, the upper computer 110 controls the timer 400 to start timing. Within a preset time interval, the control module 120 detects whether each ultrasonic probe 330 is in an idle state in real time, and the upper computer 110 detects the states of the keyboard 310 and the touch screen 320 in real time. When the control module 120 determines that each ultrasound probe 330 is in the idle state and the upper computer 110 determines that the keyboard 310 and the touch screen 320 are in the idle state, the ultrasound system is in the idle state. The upper computer 110 controls the fan 200 to work at the highest gear.
When the upper computer 110 determines that the keyboard 310 or the touch screen 320 is in the working state, or the control module 120 determines that the at least one ultrasonic probe 330 is in the working state, the ultrasonic system is in the working state. The upper computer 110 controls the fan 200 to work according to the temperature-gear relation according to the temperature of the ultrasonic system. The fan 200 is provided with a first gear, a second gear and a third gear, and the fan speeds corresponding to the first gear, the second gear and the third gear are sequentially increased. A first threshold value, a second threshold value and a third threshold value corresponding to the first gear, the second gear and the third gear are prestored in the upper computer 110, and the temperatures corresponding to the first threshold value, the second threshold value and the third threshold value are sequentially increased. When the ultrasound system is in the working state, the upper computer 110 receives the temperature of the ultrasound system and determines the relationship between the temperature and the first threshold, the second threshold and the third threshold. When the temperature is greater than or equal to the first threshold value and less than the second threshold value, the upper computer 110 controls the fan 200 to work according to 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 110 controls the fan 200 to work according to the second gear. When the temperature is greater than or equal to the third threshold value, the upper computer 110 controls the fan 200 to work according to the third gear. When the temperature is lower than the first threshold value, the temperature of the ultrasonic system is low, and heat dissipation can be omitted. When the ultrasonic system is in an idle state, the upper computer 110 judges whether the temperature of the ultrasonic system is greater than or equal to a preset temperature, if so, the fan 200 is controlled to work at a third gear until the temperature of the ultrasonic system is less than the preset temperature and keeps a preset time interval, and then the fan is operated at a first gear. The preset temperature may be a temperature corresponding to the first threshold. If the temperature of the ultrasonic system is less than the first threshold value, heat dissipation is not performed.
The condition that the ultrasonic system is switched from the working state to the idle state is that, during the timing period, if the control module 120 detects that one of the ultrasonic probes 330 is in the working state, the ultrasonic system is switched from the working state to the idle state, the timer 400 is cleared and kept to be zero, and the timer 400 is restarted until the control module 120 detects that each ultrasonic probe 330 is in the rack state again. When the control module 120 detects that each ultrasonic probe 330 is in the idle state and the upper computer 110 detects that the keyboard 310 or the touch screen 320 is in the working state, the ultrasonic system is switched from the working state to the idle state, and the timer 400 is cleared and re-timed.
The ultrasonic system judges whether the ultrasonic system is in an idle state or not by detecting the state of the input equipment, and when the ultrasonic system is in the idle state, the fan is adjusted to the highest gear to dissipate heat at the maximum rotating speed, so that the idle state gap of the ultrasonic equipment can be utilized to cool at full speed, the ultrasonic equipment is ensured to enter a working state from the idle state at a lower temperature every time, and the system stability and the service life of hardware are improved. In addition, the temperature is reduced at full speed in the idle state, and the fan is controlled to operate according to the temperature-gear corresponding relation in the working state, so that the noise generated by the ultrasonic system in the working state can be reduced.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
