Road is respectively connected in the electric power loop of device with self preservation branch road, in addition, the normally-closed contact of relay is connected with ion pump power, is connect
In the electric power loop for entering accelerator.
Further, hull outside is additionally provided with fuse.
The implementation method of medical computerized linear accelerator monitoring and protecting device provided by the present invention, it is characterised in that bag
Include following steps：
First, the ionic pump surface mounting temperature sensor in accelerator, the display control of temperature sensor cut-in temperature are passed through
Device processed, temperature sensor detect the temperature of ionic pump in real time；
Secondly, the alarm temperature of temperature display controller setting ionic pump, the self preservation temperature of ionic pump, when temperature reaches report
During alert temperature, buzzer warning；If failure is not excluded manually during buzzer warning, the temperature of ionic pump continues to be increased to
After self preservation temperature, by relay, the power supply of ionic pump is cut off.
Further, by branch road where relay and reset switch, setting self-locking circuit, constituting ion pump temperature
With the duplicate protection of reset switch.
Medical computerized linear accelerator monitoring and protecting device provided by the present invention and its implementation, not only can be real-time
The operating temperature of accelerator ionic pump is shown, while by setting alarm temperature and power-off self preservation temperature, detection is with setting temperature
0 DEG C~800 DEG C of scope, when ionic pump operating temperature is raised to the alarm temperature of setting, buzzer sends alarm, reminds work
Personnel pay attention to, search reason in time；When temperature is raised to self preservation temperature, ion pump power can be automatically cut off, so as to serve
The effectively effect of protection ionic pump.And when being connected by relay with reset switch, by the effect of latching circuit, serve only
There is the protection effect for when fix a breakdown and the double condition of manual reset, ionic pump can just resume work, substantially increasing ionic pump
Power.The use of the present invention, not only can be with the operation irregularity of early detection ionic pump simultaneously timely processing, and in the hourly worker of ionic pump 24
Any time of work can realize automatically-monitored and effective protection.In summary, the present invention improves accelerator ionic pump
Service life, huge economic losses caused by effectively prevent damage, greatlys save the cost of medical equipment, improves medical
In the life-span of equipment, there is the good effect for the normal radiotherapy for ensureing patient.
