Miniature environment field intensity early warning device capable of being worn on human body

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 [0001] The invention belongs to the technical field of radio frequency and magnetic field detection, and relates to a field strength early warning device, in particular to a human body wearable miniature environmental field strength early warning device. Background technique [0002] At present, such products are used by laboratories or measurement and measurement institutions. They are bulky and can only be used in laboratories or corresponding test pre-measurement units, which cannot meet the functions of mobile and portable fingers; The requirements are strict; it is impossible to use the wearable method for personal detection and early warning of the degree of magnetic field pollution in the environment. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a miniature environmental field strength early warning device that can be worn by the human body. [0004] The present in...
