Abstract
The utility model belongs to the radiation dose detection domain, in particular to a multi-interlocking dose monitoring device, which comprises a host machine, a detector connecting with the host machine by a data wire, as well as an alarm signal relay which controls the alarm signals, an instrument-testing relay which controls the passing of the check signals through the meter, an interlocking relay which controls the interlocking signals by the meter checking the signals, and a starting detector relay which controls the starting of the working signals of the detector. Compared with the prior survey-meter, the utility model ensures the radiation safety of the staff working in the irradiation station more reliably because of the multi-interlocking, what's more, as the adding of the starting detector relay and the interlocking relay, the function of the self-protecting of the survey-meter is improved evidently and the life-span is also prolonged effectively.
Description
Technical field
The utility model belongs to the radiation dose detection range, is specifically related to a kind of multi-joint lock dose monitor.
Background technology
In Dynarad, just need use dose monitor in the monitoring Co-60 gamma-rays dose equivalent rate.
Dose monitor is made up of a gamma ray probe and a main frame, and probe is installed in the radiation chamber, and sends monitor signal.Main frame is positioned at the pulpit, carries out the electronics processing behind the acknowledge(ment) signal and shows radiation dose.
Existing dose monitor only has the monitoring, alarming function, promptly when dose value surpasses predetermined warning level, only sends alerting signal, and can not realize multi-joint lock protection, thereby can't guarantee irradiation station staff's irradiation safety more reliably.
Summary of the invention
The utility model can not be realized the deficiency that multi-joint lock is protected at traditional dose monitor, and a kind of multi-joint lock dose monitor that can realize multi-joint lock defencive function is provided.
A kind of multi-joint lock dose monitor comprises main frame and the probe that is connected with main frame by data line, is provided with the alarm relay of control alerting signal in addition in main frame.
A kind of foregoing multi-joint lock dose monitor comprises that also control instrument is by the instrument verification relay of checking signal, the interlocking relay of control interlocking signal and the startup probe relay that control starts the probe working signal.
Advantage of the present utility model is to compare with existing detector, because of having increased multiple interlocking, has guaranteed irradiation station staff's radiation safety more reliably; And, obviously improved monitor autoprotection function owing to increased startup probe relay and interlocking relay, effectively prolonged its serviceable life.
Description of drawings
Fig. 1 is the synoptic diagram of multi-joint lock dose monitor.
Fig. 2 is the circuit block diagram of multi-joint lock dose monitor.
Among the figure:
Main frame, 2. the probe.
Embodiment
Below in conjunction with embodiment technical scheme of the present invention is further elaborated.
Embodiment
As shown in Figure 1, main frame 1 by data line be used for surveying gamma-ray probe 2 and be connected, and be provided with the interface that is used for sending alerting signal.On main frame 1, also be provided with the warning memory interface that is connected with probe 2 by data line equally.In addition, on main frame 1, also be provided with the check interface that is connected with interlocking signal and startup probe.On the main frame 1 of multi-joint lock dose monitor, also be provided with checkout button.In the inside of main frame 1 by two relays control output signals promptly by the alerting signal of alerting signal interface output and the instrument that shows on the display on by main frame 1 by the check signal; Promptly pass through the startup probe working signal and the interlocking signal of the input of check interface by two relay control input signals.
The effect of above-mentioned four kinds of signals is described below respectively:
Alerting signal: this monitor is monitored the radiation level in the radiation chamber in real time, the phenomenon of reporting to the police can not occur usually, is positioned at the detection lantern festival flicker on main frame 1 panel this moment, and the numerical value that shows on the display is background level.When having an accident (source do not put down or have radiation source), displayed value surpasses warning level, and then instrument is sent sound and light alarm, reminds the staff wouldn't enter radiation chamber, prevents to be subjected to high-dose irradiation.
Instrument is by checking signal: main frame 1 panel of detector is provided with checkout button, and when pressing this button, displayed value increases on the display, sets up a simulation alert if, surpasses warning level until displayed value and enters alarm condition.Thereby the staff can know whether operate as normal of monitor.Prevent monitor and damage, and source staff when working position misses by high-dose irradiation.
Start the probe working signal: this input signal is that probe 2 just begins to enter duty when the external world imports a signal to instrument (the source frame arrives original position).Cancel this signal (the source frame arrives working position), probe 2 quits work.2 interior elements have been prevented to pop one's head in because of the excessive problem of damaging of radiation dose value.
Interlocking signal: it is an extraneous signal giving multi-joint lock dose monitor input, and during only active arrival original position, instrument just can be connected by the check signal, and checkout button works.Prevent that the source frame from connecting probe working signal and damage probe when working position.
The circuit block diagram of multi-joint lock dose monitor as shown in Figure 2, J wherein
1Alarm relay for the control alerting signal; J
2Be the instrument verification relay of control instrument by the check signal; J
3Interlocking relay for the control interlocking signal; J
4Start the startup probe relay of probe working signal for control.
Compare with traditional dose, " instrument is by the check signal ", " starting the probe working signal " and " interlocking signal " that this instrument is newly-increased, the forced working personnel want check gauge before entering radiation chamber at every turn technically, and improve the functional reliability of instrument, thereby guaranteed irradiation station staff's radiation safety more reliably.
Claims (2)
