Abstract
A kind of cell phone microwave radiation field measuring apparatus for capableing of quantitative measurment Mobile phone antiradiation accessory radiation-proof effect. It is the testing cassete that plug, receiving element, plug sequence electrical connection form in insulation crust. The testing cassete is inserted directly into the corresponding jack of multimeter, and quantitative detection uses microwave radiation value A2, A1 before and after Mobile phone antiradiation accessory, according to formula
Calculate the effect γ (percentage) that Mobile phone antiradiation accessory eliminates cell phone microwave radiation.
Description
Affiliated technical field
The utility model relates to the field measurement apparatus of a kind of detection by quantitative mobile telephone microwave radiation, especially can in-site measurement mobile phone radiation proof accessory eliminates the measurement mechanism of mobile telephone microwave radiation effect γ (number percent).
Background technology
At present, China does not still have the national standard (comprising radiation danger criterion and measurement standard) of mobile telephone microwave radiation, the SAR standard of the common employing of known European countries, be a kind of analog measurement method, the equipment complexity is tested numerous and diverse, the strictness of requirement test environment, the expense costliness, inconvenience is carried, and general being difficult to implemented.
Some adopts prod to measure the practice (non-patent technology) of mobile phone radiation proof accessory, and is both unreliable, inaccurate again because it just utilizes the bright dark qualitative indication of light emitting diode, can not do quantitative measurment at all.For research and development and the producer and the mobile phone holder that produce mobile phone radiation proof accessory, urgently expect a kind of simple and in situ quantitation measurement mechanism more accurately, with the effect of affirmation mobile phone radiation proof accessory.
Summary of the invention
Can not measure the deficiency that mobile phone radiation proof accessory is eliminated the mobile telephone microwave radiation effect quantitatively, exactly in order to overcome existing prod technology, the utility model provides a kind of mobile telephone microwave radiation field measurement apparatus, this device can not only be measured the mobile telephone microwave radiation value by in situ quantitation, and can accurately measure the effect γ (number percent) that mobile phone radiation proof accessory is eliminated microwave radiation.
The technical scheme that its technical matters that solves the utility model adopts is: in insulation crust, plug, receiving element, plug are electrically connected, and form testing cassete.This testing cassete directly inserts in the instrument connection of multimeter correspondence.Place testing cassete nearby and keep the measurement invariant position twice on hand unit machine antenna.Aerial radiation goes out microwave energy when mobile phone is launched.Produce voltage difference at the receiving element two ends, this voltage difference produces electric current by multimeter.Multimeter institute indicating value will be indicated the size of place, testing cassete place microwave radiation energy.As if the elimination radiation effect of measuring mobile phone radiation proof accessory, use the microwave radiation value A of mobile phone radiation proof accessory front and back as long as use the utility model to measure respectively
2, A
1, according to formula
Can calculate it and eliminate the effect γ (number percent) that the width of cloth is penetrated.
The beneficial effects of the utility model are more can measure the effect (number percent) that mobile phone radiation proof accessory is eliminated microwave radiation by in situ quantitation by in-site measurement mobile telephone microwave radiation value.Only use testing cassete and the multimeter formed by receiving element etc. to measure.Simple in structure, cheap, it is convenient, accurately quick to measure.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an electrical schematic diagram of the present utility model
Fig. 2 is the longitudinal profile structural map of testing cassete
Fig. 3 is the synoptic diagram of the utility model embodiment
1. receiving elements among the figure, 2. plug, 3. multimeter, 4. testing cassete insulation crust, 5. testing cassete, 6. mobile phone, 7. antenna for mobile phone, 8. securing member.
Concrete enforcement side
In Fig. 1, connect with plug (2) separately in the two ends of receiving element (1).Plug (2) is connected with multimeter (3).
In Fig. 2, each is fastened on two pins of receiving element (1) and two plugs (2) with securing member (8) on the base plate of insulation crust (4) of testing cassete, and with good being electrically connected of plug (2) formation.
In the embodiment shown in fig. 3, testing cassete (5) directly inserts in the corresponding instrument connection of multimeter (3), to avoid connecting the interference of lead to the receiving element received signal.The antenna (7) of mobile phone (6) places multimeter (3) and testing cassete (5) nearby.Start the mobile phone emission key, read multimeter (3) and show numerical value A
2Again the radiation proof accessory is contained on the antenna for mobile phone (7), starts emission key and read multimeter (3) numerical value A
1, then this radiation proof accessory is eliminated the effect (number percent) of mobile telephone microwave radiation
Claims (4)
1, a kind of mobile telephone microwave radiation field measurement apparatus, this measurement mechanism is made up of testing cassete and multimeter, it is characterized in that: plug, receiving element, plug are electrically connected and form testing cassete in the shell of insulation.
2, mobile telephone microwave radiation field measurement apparatus according to claim 1, it is characterized in that: testing cassete directly inserts in the instrument connection of multimeter correspondence by two plugs.
