Description
Technical field the utility model belongs to the electromagenetic wave radiation detection range, a kind of specifically electronic installation that relates to the strong and weak demonstration of electromagenetic wave radiation under the commercial environment.
Technical background is present, and along with the development of personal mobile communication, more wireless network electromagnetic radiation equipment appears in people's the public environment; In the family, micro-wave oven, electromagnetic oven are also universal day by day; In the working environment, WLAN (wireless local area network), high-power mobile phone signal block device, Internet of Things radio frequency identification equipment also emerge in large numbers day by day; These trend are exposed among the more electromagnetic radiation people.Electromagnetic radiation is the hot issue of extensively being paid close attention to the influence of human body always.To the carry-on monitoring everywhere of the carrying out of electromagnetic radiation power in the environment, make the pregnant woman, Susceptible population such as weakling are important means that reduces electromagnetic radiation away from the high-intensity electromagnetic radiation source.Yet what use at present all is the electromagnetic measurement equipment of expensive, large-scale desk-top specialty, is not suitable for universal use among the people.
Summary of the invention is in order to remedy above-mentioned defective, and the purpose of this utility model provides a kind of low cost, low-power consumption, miniaturization, the electromagnetic radiation intensity display device that is fit to carry.
The utility model is realized by following technical scheme: comprise Anneta module, filtration module, detection module, central control module, keyboard load module, display module, audio frequency output module.Anneta module links to each other with filtration module by rf signal line, filtration module links to each other with the detection module by rf signal line, the detection module inserts central control module by the analog voltage signal line, keyboard input module inserts central control module by the level signal line, and central control module connects display module and audio frequency output module by digital signal line respectively.
Anneta module directly is printed on the printed circuit board (PCB), becomes built-in aerial, is easy to carry; Adopt two branch-breakages to close the monopole structure, realize the effect of the receiving electromagnetic radiation ripple of multiband.Adopt filtration module to select to need to survey the electromagnetic wave signal of frequency range.Adopt the detection module to convert the power magnitude of the current radio frequency electromagnetic that receives to level signal, and export to central control module.At central control module power-level detector is sampled and to obtain magnitude of voltage, there is the strong and weak grade point table of comparisons of electromagnetic radiance corresponding under the different magnitudes of voltage in the central control module storer in advance, by obtaining the strong and weak grade point of current electromagnetic power with this table contrast.The central controller controls display module shows the strong and weak grade point of electromagnetic power.When the power grade value surpasses setting threshold, central controller can send alarm sound by the control audio output module.Can control this device by the keyboard input and be operated in monitor state and search condition: under monitor state, this device is in the periodic duty state, promptly every certain dormancy period ability detecting electromagnetic radiation once, can effectively reduce power supply power consumption like this; Under search condition, this device then is in the state of surveying and showing the electromagnetic radiation power always, and is near more apart from electromagnetic radiation source, and this device shows that electromagnetic radiation intensity is strong more, and vice versa, therefore can be used for searching for the position of electromagnetic radiation source.
The utility model product has low cost, little, the portable characteristic of size, is specially adapted to the usefulness of electromagnetic radiation intensity demonstration under the commercial environment.
