Technical field
The utility model relates to a kind of portable dosemeter, particularly a kind of portable dosemeter of protection level that is used for the health disease control.
Background technology
The portable dosemeter of the protection level of existing health disease control adopts the pointer header indication, measurement function is only arranged, can not data storage, the no record query function, the alarm free prompt facility, especially carry out the tractor parameter timing signal in the standard source storehouse, need the indication gauge outfit is pulled down, connect the signal private cable that has screen layer, gauge outfit is caused the data that observation is measured outside the barrier shield of storehouse, source, very inconvenience.The pointer header instrument exists data to beat greatly on measuring technique, even the phenomenon of negative bias occurs.In addition, 6F22 type 9V dry cell is adopted in the power supply of system, changes inconvenience.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the purpose of this utility model is to provide a kind of portable dosemeter of protection level that is used for the health disease control, have highly sensitive, energy response wide ranges, digital display, data are preserved, record data are derived characteristics, adopt rechargeable battery simultaneously, avoided the frequent replacing of battery.Wherein the advantage of one of core component ionization chamber is simple in structure, and long-term working stability is good, and the life-span is long, need not keep in repair in the use, can be at steady operation under the rugged surroundings.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of portable dosemeter of protection level that is used for the health disease control, it is characterized in that, comprise ionization high potential assembly 1, ionization high potential assembly 1 links to each other with the high-field electrode of ionization chamber assembly 2, the passive electrode output terminal of ionization chamber assembly 2 links to each other with the current input terminal of preceding unwrapping wire road assembly 3, putting group line member 4 in the current output terminal warp of preceding unwrapping wire road assembly 3 links to each other with the signal input part of display module 5, the power output end of rechargeable battery assembly 7 links to each other with the power input of power circuit assembly 6, and the power output end of power circuit assembly 6 links to each other respectively and preceding unwrapping wire road assembly 3, in put group line member 4 and display module 5 and be electrically connected.
The RS-232 signal output part of putting group line member 4 in described links to each other with communicating circuit 8.
Come measuring radiation dosage because the utility model adopts ionization chamber assembly 2 to collect the electric charge principles, can long-term working stability good, the life-span be long, need not keep in repair in the use, can be at steady operation under the rugged surroundings; Because unwrapping wire road assembly 4 and display module 5 in being provided with are so have functions such as data storage, record, warning, communication, demonstration; Owing to be provided with communicating circuit 8, so can realize communication with PC.
Description of drawings
Accompanying drawing is a structure principle chart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are described in detail.
With reference to accompanying drawing, a kind of portable dosemeter of protection level that is used for the health disease control, comprise ionization high potential assembly 1, ionization high potential assembly 1 links to each other with the high-field electrode of ionization chamber assembly 2, ionization high potential assembly 1 provides direct current 40V ionization high pressure, be applied to the high-field electrode of ionization chamber assembly 2, the passive electrode output terminal of ionization chamber assembly 2 links to each other with the current input terminal of preceding unwrapping wire road assembly 3, preceding unwrapping wire road assembly 3 belongs to high-sensitivity amplifier, putting group line member 4 in the current output terminal warp of preceding unwrapping wire road assembly 3 links to each other with the signal input part of display module 5, in put amplification of electric current secondary and the conversion process that group line member 4 will be faint, conversion of signals is become the numerical value of demonstration, show by display module 5, the power output end of rechargeable battery assembly 7 links to each other with the power input of power circuit assembly 6, the power output end of power circuit assembly 6 links to each other respectively and preceding unwrapping wire road assembly 3, in put group line member 4 and display module 5 and be electrically connected. rechargeable battery assembly 7 is rechargeable battery, for power circuit assembly 6 provides power supply energy, power circuit assembly 6 is preceding unwrapping wire road assembly 3 with the power supply voltage stabilizing of rechargeable battery assembly 7, middle unwrapping wire road assembly 4, display module 5 provides working power. and communicating circuit 8 can be realized the communication of this dosemeter and PC.
Principle of work of the present utility model is: the operate as normal of ionization chamber assembly 2 is to utilize electric field to be collected in whole electric charges that direct ionization produced in the gas.Ionization chamber is made up of two primary electrodes, and one is high-field electrode, and another is a passive electrode.When the gamma ray of incident is mapped in the ionization chamber sensitive volume, on electrode or locular wall, get electronic secondary, electronic secondary makes gas produce ionization, and it is right to generate negative ions.When two electrodes add polarizing voltage, the positive charge that ion and electron institute present constitutes electric current to the drift and the drift of negative charge anode direction of negative electrode.The electric current of output amplifies through preceding unwrapping wire road assembly 3, and unwrapping wire road assembly 4 converts analog signals to digital information in inputing to once more in middle unwrapping wire road assembly 4, stores, processing such as alarm decision, and numerical value is shown by display module 5.Rechargeable battery assembly 7 comprises two groups of rechargeable battery set, and output voltage is 12V, for power circuit assembly 6 provides power supply energy.Power circuit assembly 6 becomes positive 5V, negative 5V and positive 3V with the battery supply voltage stabilizing, for preceding unwrapping wire road assembly 3, middle unwrapping wire road assembly 4, display module 5 provide working power.Communicating circuit 8 is a typical R S-232 change-over circuits, can realize the communication of this dosemeter and PC.
