For the convenience of understanding the embodiment, a detailed description will be given to a safety control method of an irradiation device disclosed in the embodiment of the present invention.
The first embodiment is as follows:
the embodiment provides a safety control method of irradiation equipment, which is applied to a main control unit of an irradiation equipment control system, wherein the irradiation equipment control system comprises the main control unit, an X-ray generation unit, an X-ray detection unit, a door interlock switch, an electronic door lock and a power supply of the X-ray generation unit.
The X-ray generator uses high-speed electrons to impact a metal target to generate bremsstrahlung or characteristic radiation, so that whether X-rays are generated or not can be realized by switching on or off a voltage applied to a bulb accelerating the electrons, namely when the voltage of the bulb is switched on, the high-speed electrons impact the metal target to generate X-ray radiation, however, the X-rays have radiation damage to human tissues, so that the irradiation equipment needs to be safely controlled to prevent safety accidents of X-ray leakage.

The main control unit is used for controlling other units of the irradiation equipment control system, the X-ray generating unit is used for generating X-rays, the X-ray detecting unit is used for detecting the radiation quantity of the X-rays of the irradiation equipment control system, the door interlocking switch and the electronic door lock are used for closing the irradiation equipment control system, and the power supply of the X-ray generating unit supplies power to the X-ray generating unit.
Based on the above description, referring to the flowchart of the safety control method of the irradiation equipment shown in fig. 1, the safety control method of the irradiation equipment includes the following steps:
and S102, receiving a first signal sent by the door interlock switch, and determining whether a user sends a door opening request for the electronic door lock or not based on the first signal.
The user triggers the door interlock switch, the door interlock switch can send a first signal to the main control unit, and the main control unit can determine whether the user sends a door opening request for the electronic door lock after receiving the first signal.
The method provided in this embodiment may determine that the irradiation equipment control system is safe if a plurality of conditions are satisfied, and determine whether the user sends a door opening request for the electronic door lock, i.e., a first condition. In this embodiment, if it is determined that the user sends a door opening request for the electronic door lock, the first condition may be considered to be satisfied.
And step S104, acquiring a detection signal sent by the X-ray detection unit, and determining whether the radiation quantity of the X-ray is smaller than a preset threshold value or not based on the detection signal.
The X-ray detection unit can detect the radiant quantity of the X-rays and send a detection signal representing the radiant quantity of the X-rays to the main control unit. The main control unit may determine whether the radiation amount of the X-rays is less than a preset threshold value according to the received detection signal. Whether the radiation amount of the X-rays is smaller than the preset threshold value is the second condition of the present embodiment, and if the radiation amount of the X-rays is smaller than the threshold value, the second condition may be considered to be satisfied.
And step S106, determining whether the communication between the main control unit and the X-ray generating unit is normal.
Whether the communication between the main control unit and the X-ray generation unit is normal is the third condition of this embodiment, and if the communication between the main control unit and the X-ray generation unit is normal, the third condition may be considered to be satisfied.
Step S108, if the user sends a door opening request, the radiation quantity of the X-ray is less than a threshold value, and the communication between the main control unit and the X-ray generating unit is normal; and sending a command for representing the safety of the irradiation equipment to the electronic door lock.
If the first condition, the second condition and the third condition are all satisfied (namely, the user sends a door opening request, the radiation quantity of the X-ray is less than the threshold value, and the communication between the main control unit and the X-ray generating unit is normal), the irradiation equipment control system can be considered to be safe, a command representing the safety of the irradiation equipment can be sent to the electronic door lock, and the user can safely open the electronic door lock.
According to the safety control method of the irradiation equipment provided by the embodiment of the invention, if a user sends a door opening request, the radiation quantity of X rays is smaller than a threshold value, and the communication between the main control unit and the X ray generation unit is normal, the main control unit of the irradiation equipment control system sends a command to the electronic door lock, so that the user can safely open the electronic door lock. The mode can improve the safety and the reliability of the irradiation equipment and prevent the safety accident of X-ray leakage.
Example two:
the present embodiment provides another safety control method for irradiation equipment, which is implemented on the basis of the above embodiments. Referring to a flow chart of another safety control method of an irradiation facility shown in fig. 2, the safety control method of the irradiation facility in the embodiment includes the following steps:
and S202, receiving a first signal sent by the door interlock switch, and determining whether a user sends a door opening request for the electronic door lock or not based on the first signal.
Referring to the schematic diagram of an irradiation equipment system shown in fig. 3, power supplies of the X-ray generation unit, the X-ray detection unit, the door interlock switch, the electronic door lock and the X-ray generation unit are all connected with the main control unit, and the X-ray generation unit is connected with the door interlock switch.
Specifically, the main control Unit may be a general-purpose Processor, including a Central Processing Unit (CPU), a Network Processor (NP), and the like, and may also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), or other Programmable logic devices.
Specifically, the X-ray detection unit may be a scintillation crystal coupled to a photosensitive element (e.g., a Csl scintillator + Si photodiode or a photoresistor), the X-ray generation unit may be an X-ray tube (e.g., a stationary anode X-ray tube NDI-161), and the power supply of the X-ray generation unit may be an XRV high voltage generator. The door interlock switch is used for receiving user instructions, and the electronic door lock can be an electromagnet or an electromagnetic bolt lock.
The control process of the system can be seen in a schematic diagram of a control mode of the irradiation equipment system shown in fig. 4. As shown in fig. 4, when a user needs to open the shield door, a door interlock switch (which may be a mechanical button, a button virtually on the display screen, or a switch with a sound or image recognition function, etc.) is triggered, and this embodiment does not limit the specific manner thereof, as long as it can receive a door opening instruction required by the user and send the instruction signal to the main control unit), at this time, the door interlock switch sends a first signal to the main control unit, and simultaneously sends a second signal to the X-ray generating unit, and the X-ray generating unit receives the second signal sent by the door interlock switch.
The main control unit may determine whether the user sends a door opening request for the electronic door lock by: acquiring a second signal received by the X-ray generating unit; matching the first signal with the second signal to obtain a matching result; if the matching result represents that the matching is successful, the user sends a door opening request aiming at the electronic door lock; and if the matching result represents that the matching is unsuccessful, the user does not send a door opening request aiming at the electronic door lock.
As shown in fig. 4, after receiving the first signal, the main control unit queries the X-ray generation unit whether to receive the second signal, compares the first signal with the second signal after confirming that the second signal is received, and if the two signals are successfully matched, the main control unit considers that the user has sent a door opening request and the door opening request meets the first condition.
Preferably, the first signal and the second signal are both digital signals, and the first signal and the second signal can be directly matched by the arrangement without analog-to-digital conversion or comparison after signal processing, so that signal distortion caused by signal processing is reduced, and accuracy is improved.
Step S204, acquiring a detection signal sent by the X-ray detection unit, and determining whether the radiation quantity of the X-ray is smaller than a preset threshold value or not based on the detection signal.
And then, the main control unit can inquire the detection signal of the X-ray detection unit, and if the radiation quantity detected by the X-ray detection unit is lower than a threshold value, the main control unit considers that the second condition of opening the door is met.
Preferably, when detecting the amount of radiation, a plurality of groups of combinations of the scintillation crystal and the photosensitive element of the X-ray detection unit may be set, and the main control unit may acquire a detection signal containing a plurality of groups of measurement values sent by the X-ray detection unit; if the plurality of groups of measured values are smaller than the preset threshold value, the radiation quantity of the X-ray is smaller than the threshold value; if any one of the sets of measured values is greater than or equal to the threshold value, the amount of X-ray radiation is not less than the threshold value. That is, the measured value of each combination is compared with the threshold value, and if the detected value of any combination is higher than or equal to the threshold value, the second condition for opening the door is not met.
Preferably, the detection result of a specific position and the irradiation cumulative dose value preset in the main control unit and at the specific position can also be matched during the radiation amount detection, for example: determining whether the detection signal of the designated position is matched with a prestored irradiation cumulative dose value of the designated position; if so, a step of determining whether the amount of radiation of the X-rays is less than a preset threshold value based on the detection signal is performed.
And matching the detection result of the specific position with the irradiation cumulative dose value preset in the main control unit and at the specific position, if the detection result can be correctly matched, considering that the detection result at the position is credible, and further comparing the detection result with a threshold value, and if the detection result can not be correctly matched, considering that the detection result at the position is not credible, and not comparing the detection result with the threshold value. The irradiation cumulative dose value can be determined according to the power of the X-ray generating unit, the distance between the specific position and the X-ray generating unit and the irradiation time and is pre-arranged in the memory of the main control unit.
Step S206, determining whether the communication between the main control unit and the X-ray generating unit is normal.
The main control unit can confirm whether the communication with the X-ray generating unit is interrupted, and if the communication is not interrupted, the main control unit considers that the third condition of opening the door is met.
Step S208, if the user sends a door opening request, the radiation quantity of the X-ray is less than a threshold value, and the communication between the main control unit and the X-ray generating unit is normal; and sending a command for representing the safety of the irradiation equipment to the electronic door lock.
The main control unit can send a command to the electronic door lock so that a user can safely open the electronic door lock, and under the condition that the communication between the main control unit and the X-ray generating unit is normal, the power supply of the X-ray generating unit does not need to be cut off, because frequent switching on/off of the power supply can cause premature fatigue and damage of the power supply, especially under the condition that the power supply is a high-voltage generator.
Step S210, if the user does not send a door opening request, or the radiation quantity of the X-ray is greater than or equal to a threshold value; a command indicating that the generation of X-rays is stopped is transmitted to the X-ray generation unit, and a command indicating that the power supply is turned off is transmitted to the power supply.
If the user does not send a door opening request, or the amount of X-ray radiation is greater than or equal to the threshold, the main control unit may first send a command to the X-ray generation unit to stop generating X-rays, and then send a command to the X-ray generation unit to turn off the power supply. If the communication between the main control unit and the X-ray generating unit is interrupted, the power supply of the X-ray generating unit can be directly cut off, for example: and if the communication between the main control unit and the X-ray generating unit is interrupted, sending a command for indicating to disconnect the power supply to the power supply.
According to the method provided by the embodiment of the invention, when the conformity of the first condition is judged, the door interlocking signals (the first signal and the second signal) are subjected to cross verification, so that the accuracy of the door opening request of a user can be effectively ensured. When the safety is failed, the radiation detection unit in the electric door detects whether the internal radiation quantity is higher than a safety threshold value, when the internal radiation quantity is higher than the safety threshold value, the electric door lock continuously acts, and a user cannot open the shielding door. The power supply of the X-ray generating unit is directly controlled by the main control unit, and the power supply can be directly cut off after the communication interruption between the main control unit and the X-ray generating unit is detected, so that the safety is further improved.
In addition, the irradiation equipment control system further includes a display unit, and after the step of the user not sending a door opening request, the radiation amount of the X-ray is greater than or equal to the threshold, or the communication between the main control unit and the X-ray generation unit is interrupted, as shown in fig. 4, the method further includes: and sending an alarm signal to a display unit.
In addition, the method further comprises: confirming whether the electronic door lock really needs to be opened by a user; if so, a command is sent to the X-ray generation unit indicating that the generation of X-rays is stopped, and a command is sent to the power supply indicating that the power supply is disconnected. Referring to fig. 5, another schematic diagram of a control method of an irradiation equipment system is shown, as a preferred scheme, after an alarm signal is sent, a display unit may remind a user whether to confirm to open a shielding door, if the opening is confirmed, the X-ray generation unit is controlled to stop generating X-rays, then the power supply of the X-ray generation unit is controlled to be disconnected, but under the condition that the communication between the main control unit and the X-ray generation unit is interrupted, the power supply of the X-ray generation unit is directly controlled to be disconnected, and if the shielding door is not confirmed to be opened, the operation is ended.
