Abstract
The invention relates to a miniature environment field intensity early warning device capable of being worn on a human body. The miniature environment field intensity early warning device comprises a miniature antenna connected with an amplifier through a wire. The amplifier is connected with a frequency counter and a CPU memorizer through wires respectively. The CPU memorizer and the frequency counter are connected with a CPU arithmetical unit through wires respectively. The CPU arithmetical unit is connected with an indicator and a power supply through wires respectively. A weak electromagnetic signal detected by the miniature antenna is divided into two routes after passing through the amplifier, wherein one route enters the CPU memorizer, and the other route enters the frequency counter. The frequency counter transmits a frequency signal generated by a magnetic field to the CPU arithmetical unit, and finally outputs the processing result through the indicator. The magnetic field and the frequency are detected at the same time, the defects that when electromagnetic pollution detection is conducted, the requirement for the antenna is too high, and convenience and wearability can not be achieved are overcome, an alarm is given for the magnetic field environment exceeding human safety, and therefore a user can be prompted that the user is in a standard-exceeding electromagnetic environment, safety measures of getting away or achieving isolation can be taken in time, and human health is ensured.
Description
Technical field
The invention belongs to radio frequency and detection techniques field, magnetic field, relate to a kind of field intensity precaution device, be specifically related to the miniature environment field intensity precaution device that a kind of human body is wearable.
Background technology
At present this type of product is laboratory or measurement and metrology mechanism is used, bulky, only can be used in laboratory or corresponding test estimate unit, cannot meet mobile and portable finger function; Antenna specialty becomes to uprise, and requires strict to environment for use; Detection and early warning can not be made for individual to magnetic pollution degree in environment in the mode of dressing.
Summary of the invention
The problems referred to above that the present invention exists to solve prior art, provide the miniature environment field intensity precaution device that a kind of human body is wearable.
The present invention adopts following technical scheme:
The miniature environment field intensity precaution device that a kind of human body is wearable, comprise miniature antenna, miniature antenna is connected with amplifier by wire, amplifier is connected with frequency counter, CPU storer respectively by wire, described CPU storer, frequency counter are connected with CPU arithmetical unit respectively by wire, and CPU arithmetical unit connects with indicator, power supply respectively by wire; The weak electromagnetic signal that described miniature antenna detects is by after amplifier point of two-way, and a road enters CPU storer, and another road enters frequency counter; The frequency signal transmission that magnetic field produces by frequency counter is to CPU arithmetical unit, and result is exported by indicator the most at last.
Described miniature antenna is the antenna of 2CM length.
Described CPU arithmetical unit is DSP arithmetical unit.
Described precaution device is installed in portable product.
The invention has the beneficial effects as follows: adopt magnetic field and frequency to detect to overcome the antenna requirement when doing electromagnetic pollution and detecting with the comparative approach of basic data excessive simultaneously, cannot portable with dress shortcoming, different to the absorptivity of different frequency according to human body, by data based on the absorptivity of each for human body frequency range, compare with secure data after examining detecting data compensated foundation data.A kind of magnetic field with microminiature wire pair surrounding environment becomes by force carries out freight volume detection, portablely can even give decoration and be worn on human body, propose to report to the police to the magnetic field environment exceeding human-body safety, when being in point out user the electromagnetic environment exceeded standard, in time away from or the safety practice such as isolation, to ensure health.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, miniature antenna; 2, amplifier; 3, frequency counter; 4, CPU storer; 5, CPU arithmetical unit; 6, CPU basic data and each frequency range absorption data of human body; 7, indicator; 8, power supply.
Embodiment
As shown in Figure 1, the invention provides the miniature environment field intensity precaution device that a kind of human body is wearable, comprise miniature antenna 1, miniature antenna 1 is connected with amplifier 2 by wire, amplifier 2 is connected with frequency counter 3, CPU storer 4 respectively by wire, described CPU storer 4, frequency counter 3 are connected with CPU arithmetical unit 5 respectively by wire, and CPU arithmetical unit 5 connects with indicator 7, power supply 8 respectively by wire; Described miniature antenna 1 is the small size antenna of 2CM length, the magnetic field intensity of miniature antenna 1 perception surrounding environment by the weak electromagnetic signal detected by being divided into two paths of signals after amplifier 2, one road signal enters CPU storer 4 and stores preservation, and another road enters the frequency that frequency counter 3 reads now magnetic field generation; The frequency signal transmission that magnetic field produces by frequency counter 3 is to CPU arithmetical unit 5, the basic data under corresponding frequencies is transferred from CPU basic data and each frequency range absorption data 6 of human body, offset data in basic data under this frequency and the actual detecting data be kept in CPU storer 4 carry out contrast and compensate, make comparisons with the magnetic field value compensated and safety value, result is exported by indicator 7 the most at last, when being greater than the prompting of safety value alarm.
Electromagnetic field signal in environment is detected by miniature antenna 1, due to environment use singularity (human body wearing) and antenna be small-sized, now signal can be very faint.The weak electromagnetic signal that miniature antenna 1 detects is amplified by amplifier 2, and the signal after amplifying is divided into two-way process, meter frequency circuit of leading up to enters frequency counter 3, the storer that one tunnel enters CPU in the mode of magnetic strength is preserved, CPU reads frequency counter 3 and transmits the frequency signal of coming, in CPU basic data and each frequency range absorption data 6 of human body, transfer the basic data under corresponding frequencies, described basic data comprises: the loss of miniature antenna 1 under A, this frequency simultaneously; The absorptivity of human body radio frequency electromagnetic signal under B, this frequency; The safety standard data in C, magnetic field; Offset data under D, this frequency.Offset data under this frequency and the actual detecting data be kept in CPU storer 4 are carried out contrast compensate, the safety standard data in the data after compensation and magnetic field are compared, result is relatively showed by indicator or display, allows user know to know the radiation level of electromagnetic field in residing environment.Because major part is data processing, so hard portion is less, so product is small, can be used as unit product, also can be integrated in portable product, as wrist-watch, mobile phone etc.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection scope of the present invention.
