Description

The radioactive radiation detection of handset

Technical field

The utility model relates to a kind of radioactive radiation detection of handset.

Background technology

The radiation detection transducer: the nuclear radiation transducer that present volume can be done very for a short time has Geiger tube, semiconductor detector etc.And use maximum in individual field is exactly Geiger tube, and little Geiger tube can be accomplished diameter 6mm at present, length 25mm, in addition littler, possessed the possibility that is incorporated in the mobile phone.

The Geiger tube principle: Geiger counter is designed to ionisation of gas character according to ray.The common structure of Geiger tube is to charge into low density gas (normally to have mixed the rare gas of halogen in the metal tube airtight with megohmite insulant of two ends, as helium, neon, argon etc.), along an one metal wire electrode is installed on the axis of pipe, and between metal pipe-wall and wire electrode, add voltage a little less than gas breakdown voltage in the pipe.So in the normal state, gas does not discharge in the pipe; And in high-velocity particles is injected pipe the time, the energy of particle makes that gas ionization conducts electricity in the pipe, produces gas discharge phenomenon rapidly between filament and tube wall, thereby exports a pulsed current signal.Pulse signal becomes the square-wave signal of standard, then enter counter after high pressure isolation, amplification, smith trigger etc. are handled.Discharge when counter is automatically noted each particle and flown in the pipe can detect the number of particle thus.By adjusting the voltage between tube wall and the wire, can detect dissimilar radiation as can be known.For the human body safety in the daily life, to detect gamma-rays.

As shown in Figure 1, be Geiger tube detector concept block diagram: Geiger tube provides bias voltage by high-voltage driving circuit, and institute's making alive difference is then to different radiation-sensitive degree differences.The operating state of high-voltage driving circuit is controlled by control circuit, and control signal is provided by main control chip.The pulse output signals of Geiger tube can the output square-wave signal after high pressure isolation, signal arrangement amplifying circuit are handled.Wherein counter and data outputting module can be used chip microcontroller separately, pass through the serial ports Data transmission with main frame; Also can use the counter on the main control chip to realize.Specific implementation is decided on the quantity of mobile phone base band chip counter.Cell phone platform: current most of cell phone platforms, not only integrated powerful processor, and also the device peripheral hardware is numerous, rich interface, and autgmentability is strong.Integrated in addition equipment such as GPS, wifi, bt, cam, mass storage.Mobile phone is the maximum personal terminal of the present volume of holding.

Though it is very portable that common in the market personal dosimeter also can accomplish, general interface is simple and crude, only can show numerical value, and uncomprehending people is difficult to understand its implication to radiation standard.The operation interface of this kind equipment is not directly perceived in addition, and is too complicated for ordinary consumer.So a kind of novel radioactive radiation detection of handset is badly in need of being developed.

Summary of the invention

The utility model is at the proposition of above problem, and development radioactive radiation detection of handset.The technological means that the utility model adopts is as follows:

A kind of radioactive radiation detection of handset comprises baseband chip, radio frequency and input module, and described radio frequency is connected with baseband chip by data wire respectively with input module; It is characterized in that also comprising radiation sensing module, data-interface and memory; Described radiation sensing module sends to the signal of sensing in the baseband chip and handles, and the storage after handling through baseband chip sends on the external equipment in memory and/or by data-interface.Described radiation sensing module is made of the Geiger tube testing circuit.Also comprise audio output unit and LCD; Described audio output unit and LCD report to the police and show be connected signal strength signal intensity that the radiation sensing module is passed back of baseband chip respectively.

It is conspicuous that the utility model is compared its advantage with prior art, this mobile phone is by the powerful data-handling capacity of current phone platform, network connecting function, not only testing result can be shown intuitively, and can compare the detection data of immediate inquiring professional institution easily with various countries, international standard.In addition, can detect radioactive radiation intensity and reservation record in the living environment at any time.When radiation intensity exceeds standard, can remind the user, and data can be uploaded by network, also can conveniently inquire about the data that professional mechanism for monitoring is announced simultaneously.The present invention is integrated into the personal dosimeter on the mobile phone, has increased portability, has made full use of the data-handling capacity of mobile phone.Be applicable to indoor and outdoor surroundings detection, building materials radiation detection in the home, radioactive source unit: as the early warning of hospital, steel mill's surrounding environment.
