Abstract
A radiation chamber safety control device comprises a power supply, a production control system and a safety interlocking system which are connected into a loop. Besides, a fingerprint reader is in series connection inside the loop. By the aid of a fingerprint identification system, the radiation chamber safety control device can effectively prevent non-work people from mistakenly entering a radiation chamber and illegally starting a radiation device so as to prevent accidents, and has the advantages of simple structure, high positioning precision, fine safety and capability of ensuring normal radiation production.
Description
Technical field
The utility model relates to irradiation safety technique field, is specifically related to a kind of radiation chamber safety control.
Background technology
Radiation processing technology is used widely, and plays more and more important effect in national life in the sterilization of food fresh keeping, medical supplies and medicine, synthesize and the fields such as modification, elimination insect pest of polymkeric substance.
General irradiation devices are to utilize
60Co produces gamma-rays object is carried out irradiation processing, can produce very high dose rate when irradiation, when accident takes place, is in the interior people of radiation chamber and can accepts lethal dose in several minutes or several seconds.In case the accident of meeting accident will cause serious casualties, great economic loss and bad social influence.
For guaranteeing the sound development of irradiation technique, the radiation safety problem is the operating matters of utmost importance of irradiation devices all the time, because it is directly connected to environment, staff and public personnel's health and safety.For addressing this problem, it is outside the pale of civilization that irradiation processing enterprise removes the safety management rules of setting up the turnover radiation chamber, at radiation chamber maltilevel security interlock mechanism is installed and is very important, and has only after all safety interlockings satisfy condition, and the staff just can enter radiation chamber.And still there is the defective of no Intelligent Recognition function in present irradiation devices safety interlock system, amateur staff is strayed into radiation chamber or the inoperative personnel illegally open irradiation devices, production causes great potential safety hazard to irradiation, therefore, the irradiation devices safety control system of setting up personal identification is very important.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of radiation chamber safety control, it can prevent effectively that the inoperative personnel are strayed into radiation chamber, and the inoperative personnel illegally open irradiation devices, thereby guarantee the safe operation that irradiation is produced, avoid the generation of major accident.
For achieving the above object, the utility model adopts following technical scheme:
A kind of radiation chamber safety control comprises power supply, production control system, safety interlocking system, and described power supply, production control system, safety interlocking system connect into a loop, and also are connected in series with a Fingerprint Identification Unit in this loop.
Described safety interlocking system includes dose monitoring system, radiation chamber illuminator, carrier chain motor overload protection system, water quality monitoring system, personnel's mistake and stays pullswitch, optoelectronic switch.
The radiation chamber safety control that the utility model is set forth, its beneficial effect is:
1, the utility model can prevent effectively that by adopting fingerprint recognition system the inoperative personnel are strayed into radiation chamber, and the inoperative personnel illegally open irradiation devices, prevents the generation of accident;
2, it is simple in structure, bearing accuracy is high, security is good, can guarantee normally carrying out of irradiation production.
Description of drawings
Fig. 1 is the structural representation of a kind of radiation chamber safety control of the utility model.
Embodiment
Below, in conjunction with the accompanying drawings and embodiment, radiation chamber safety control of the present utility model is described further, so that clearerly understand the utility model technological thought required for protection.
As shown in Figure 1, be a kind of radiation chamber safety control of the present utility model, it comprises power supply, safety door, Fingerprint Identification Unit, production control system, the safety interlocking system that connects into a loop; Dose monitoring system, radiation chamber illuminator, carrier chain motor overload protection system, water quality monitoring system, personnel's mistake are stayed pullswitch, optoelectronic switch.As long as any one building block of safety interlocking system is received bad production information, the safety interlocking system will disconnect, just can be with the loop cut-out at itself and power supply place, thus make production control system out of service.
Above-mentioned radiation chamber safety control is in use:
Before entering radiation chamber, the staff enters production control system with fingerprint, falls the source after sourse instruction falls in input, falling after the source puts in place, mechanical key cuts out and rises source current, pulls up the key of band radiation monitor, with this key operated safety door mechanical switch, pull up key, with the fingerprint opening safety door; Safety door fingerprint control section is cold under the situation of key not having, so also can't open safety protective door; Simultaneously, safety door and dose monitoring system interlocking have only radiation dose to be lower than limit value, could be with the fingerprint opening safety door.Radiation chamber illuminator and irradiation devices working power, dose monitor interlocking have only when radiation dose is lower than limit value, and the radiation chamber illumination is opened, and personnel just can enter radiation chamber.
When rising source preparation, the staff makes an inspection tour radiation chamber, presses all pushbutton switches of clearing out a gathering place of radiation chamber, closes the radiation chamber safety door, behind key operated power supply, enters production control system with fingerprint, and the lifting origin system could normally come into operation; Utilize effectively control radiation chamber personnel's turnover of fingerprint intelligent identification, prevent the operation of unexpected personnel production control system.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to technical scheme described above and design.
