The inventor researches the radiation damage of the electronic component in the radiation environment, and finds that the radiation damage of the electronic component is reduced when the electronic component is in a non-working state in the radiation environment, so that the electronic component is protected. Referring therefore to fig. 1, the present application provides a system for increasing the radiation lifetime of electronic components. The system for improving the radiation life of electronic components includes a radiation therapy device 10, a power supply 20, a radiation dose monitoring device 30, and a power supply controller 40. The radiation therapy device 10 comprises a radiation source 11 and electronic components 12 located within an emission area of the radiation source. The electronic component 12 is located in the radiation area in this application, which means that the electronic component is located in a radiation range of the primary radiation emitted by the radiation source 11 and/or of scattered radiation generated in the system. The power source 20 is electrically connected to the electronic component 12 for supplying power to the electronic component 12. The radiation dose monitoring device 30 is disposed in the radiation area and adjacent to the electronic component 12, and is used for monitoring a radiation dose value of a position where the electronic component 12 is located. The adjacent arrangement may be such that the radiation dose monitoring device 30 is in contact with the electronic component 12, or may be spaced apart. The input end of the power controller 40 is connected with the radiation dose monitoring device 30 in a communication manner, the output end of the power controller 40 is electrically connected with the power source 20, and the power controller 40 is used for controlling the power supply state of the power source 20 according to the radiation dose value of the position of the electronic component 12.
It is understood that the electronic component 12 is a component including an electronic component. The type and number of the electronic components 12 are not particularly limited. The electronic component 12 may be a device that is greatly affected by a metal shielding case. In one of the possible implementations, the electronic component 12 is an electronic component 12 with a human-machine interaction function or an electronic component 12 with a motion control function.
It is understood that the arrangement position and number of the power supplies 20 are not limited in particular, as long as the power supply rails required by the electronic component are realized, such as converting the input +24V voltage into +12V for the specific circuit in the functional module. In one embodiment, the power source 20 may be located near the electronic component 12 to reduce the voltage drop caused by the power during transmission. In one possible implementation, the power source 20 is disposed in a position that is substantially non-radiated or radiated to a degree within what is considered acceptable in the industry. The power source 20 can be used to provide a relatively higher voltage than the electronic component 12, and the voltage conversion unit can be used to convert the power to the voltage value required by the electronic component 12 after the power is transmitted to the electronic component 12. One power supply 20 may supply power to a plurality of the electronic components through a plurality of power rails, respectively. In another implementable manner, the same number of power supplies 20 as the electronic components may be provided. One power supply 20 supplies power to only one electronic component.
It is to be understood that the structure and the specific position of the radiation dose monitoring device 30 are not particularly limited as long as the radiation dose value at the position of the electronic component 12 can be monitored. In one embodiment, the radiation dose monitoring device 30 is one or more of an ionization chamber type dose monitor, a scintillation detector, and a semiconductor detector.
It is to be understood that the structure and the arrangement position of the power controller 40 are not particularly limited. In one implementation, the power supply 20 and the radiation dose monitoring device 30 are disposed proximate to the electronic component 12, and the power supply controller 40 is disposed remote from the radiation source 11. The power controller 40 is disposed at a position far away from the radiation source 11 in this application, which means that the power controller 40 is disposed at a position out of the radiation range of the main radiation emitted by the radiation source 11 and/or scattered radiation generated in the system or at a position considered acceptable in the industry.
The power controller 40 may comprise a storage unit for storing a preset radiation dose value. It will be appreciated that different electronic components may be subjected to different radiation doses, and therefore different radiation dose preset values may be set for different electronic components. The radiation dose monitoring device 30 sends the monitored radiation dose value of the position of one of the electronic components 12 to the power controller 40. When the power controller 40 determines that the radiation dose value is greater than the preset radiation dose value, the power controller 40 controls the power supply 20 to cut off the power supply to the electronic component 12, so that the electronic component 12 is in a non-working state, and the radiation damage to the electronic component 12 is reduced. Compared with the traditional mode of arranging the metal shielding shell, the mode reduces the design cost and weight and improves the use convenience.
It is understood that the manner in which the power controller 40 controls the power source 20 to cut off the power supply to the electronic component 12 is not particularly limited. In one embodiment, the system for improving the radiation life of the electronic component further comprises an execution unit 41. Referring to fig. 2, a first end of the execution unit 41 is electrically connected to the power supply 20, and a second end of the execution unit 41 is electrically connected to the electronic component 12. The third terminal of the execution unit 41 is connected to the power controller 40. In this embodiment, the power controller 40 is connected to the power source 20 through the execution unit 41. When the radiation dose value of the position where the electronic component 12 is located is higher than the preset radiation dose value, the power supply of the power supply 20 to the electronic component 12 is cut off by the execution unit 41. That is, the execution unit 41 may be disposed on each power rail, and when the power controller 40 determines that the radiation dose value is greater than the radiation dose preset value, the power controller 40 controls the execution unit 41 to cut off the power supply of the power 20 to the electronic component 12.
In one implementation, the execution unit 41 is a switch circuit or other integrated circuit that controls the power supply 20 to be powered on and off. The switch tube in the switch circuit can be a relay or an MOS tube. The integrated circuit that controls the power on and off of the power supply 20 may be integrated in the power supply controller 40.
According to the method, the radiation dose value of the position of the electronic component 12 is monitored in real time by using the radiation dose monitoring device 30, and when the radiation dose value monitored by the radiation dose monitoring device 30 is higher than the preset radiation dose value, the power controller 40 controls the execution unit 41 to cut off the power supply of the power supply 20 to the electronic component 12, so that the electronic component 12 is in a non-working state, the radiation damage of the electronic component 12 is reduced, and the service life of the electronic component is prolonged.
In one embodiment, the system for improving the radiation life of the electronic component further comprises a communication unit 60.
Referring to fig. 3, the communication unit 60 is in communication connection with the electronic component 12, the power supply 20 and the radiation dose monitoring device 30, and is configured to transmit the operating state information of the electronic component 12, the operating state information of the power supply 20 and the radiation dose value information to the remote control terminal 200 and receive an operating instruction of the remote control terminal 200. The operating state information of the power supply 20 may include power-on state information, power-off state information, or other operating state information of the power supply. The remote control terminal 200 may be a computer monitor, a mobile phone or other devices capable of receiving and transmitting control commands. The communication unit 60 may also be in communication connection with the power controller 40, and is configured to send the radiation dose value information to the power controller 40.

The structures and the connection relations of the radiotherapy device 10, the power supply 20 and the power supply controller 40 are similar to those of the radiotherapy device 10, the power supply 20 and the power supply controller 40 in the above embodiments, for example, when the system for improving the radiation life of electronic components does not include the execution unit 41, the connection relations of the radiotherapy device 10, the power supply 20 and the power supply controller 40 are similar to those shown in fig. 1; when the system for improving the radiation life of the electronic components includes the execution unit 41, the radiation therapy apparatus 10, the power supply 20 and the power supply controller 40 are connected in a similar manner to the connection shown in fig. 2.

It is to be understood that the structure of the operation state judgment unit 50 is not particularly limited as long as it can judge whether the electronic component 12 needs to be operated. In an implementation manner, the operation state determination unit 50 may identify an operation state in which the radiotherapy apparatus is currently located, and may determine whether the electronic component 12 needs to operate at this time according to the identified operation state of the radiotherapy apparatus. The operating state determining unit 50 sends the monitored state of whether any one of the electronic components 12 needs to operate to the power controller 40. When the working state determining unit 50 detects that one of the electronic components 12 does not need to work, the power controller 40 controls the executing unit 41 or directly controls the power supply 20 to cut off all or part of the power supply 20 to the electronic component 12, so that the electronic component 12 is in a non-working state, and radiation damage to the electronic component 12 is reduced. Compared with the traditional mode of arranging the metal shielding shell, the mode reduces the design cost and weight and improves the use convenience.
When the working state judging unit 50 detects that one of the electronic components 12 needs to work, the power controller 40 controls the execution unit 41 or directly controls the power supply 20 to turn on the power supply of the power supply 20 to the electronic component 12. In addition, the working state information of the radiotherapy equipment can be synchronized through the electronic component communication interface and sent to the remote control terminal 200, or the electronic component communication interface automatically wakes up the remote control terminal 200, so that the remote control terminal 200 controls to turn on the power supply of the relevant components of the radiotherapy equipment, and enters a normal working mode, and meanwhile, the state information is synchronized.
In this embodiment, the working state determining unit 50 is used to monitor whether the electronic component 12 needs to work in real time, and when one of the electronic components 12 to be monitored by the working state determining unit 50 does not need to work, the power controller 40 controls the power supply to cut off the power supply to the electronic component 12, so that the electronic component 12 is in a non-working state, and further, the radiation damage to the electronic component 12 is reduced, thereby improving the service life of the electronic component. It can be understood that the working state determining unit 50 can directly monitor whether the electronic component 12 is currently in a working state, and if the electronic component 12 is not in the working state, the power controller 40 controls the power supply to cut off the power supply to the electronic component 12, so that the electronic component 12 is in a non-working state, and further, the radiation damage of the electronic component 12 is reduced, thereby improving the service life of the electronic component; if in the working state, the working state judgment unit 50 continuously monitors the working state of the electronic component 12. During operation of the electronic component 12, the radiation dose of its operating environment is continuously monitored simultaneously by means of the radiation dose monitoring device 30, avoiding damage.

The external device refers to other components directly or indirectly connected to the electronic component 12.
