In the invention, the detector comprises a detection module consisting of a receiving sensor detection probe and a receiving detection circuit, and also comprises a detection module consisting of a transmitting sensor detection probe and a transmitting detection circuit, as shown in figure 2, the two detection probes can be physically combined into one. The receiving detection circuit judges whether the target equipment emits infrared rays or not by using a receiving detection probe, gives a detection result according to a received signal, and prompts a user in an acoustic and optical form, such as the content of a rounded rectangle on the left side of the figure 2. The other is a transmission detection circuit, which outputs a set frequency signal, and the transmission probe transmits an infrared light signal according to a specified frequency for the receiving tube of the target device to be tested to receive, after the target device receives the infrared light, the target device generates a frequency pulse level signal which changes along with the detector, and according to the electromagnetic principle, the changed level signal generates a very weak electric field and magnetic field signal near the wire connected with the circuit board of the tested device, as shown in fig. 3. The probe head transmits the signal to a preamplifier composed of a triode and the like for amplification. And amplifying by a later stage, selecting the frequency of the specific frequency signal, judging by a singlechip, determining whether the specific frequency signal is consistent with the actively transmitted specific frequency signal, and finally obtaining a judgment result.
In the invention, the receiving detection module judges whether the target equipment emits infrared rays by using a receiving detection probe, gives a detection result according to a received signal and prompts a user in an acoustic and optical mode. The emitting module is controlled by the singlechip to output a specific frequency signal, the specific frequency signal is converted into an infrared light signal with specified frequency through the emitting detection probe to be received by a receiving circuit of target equipment, the target equipment generates a frequency pulse level signal emitted along with the detector after receiving infrared rays under the intact condition, and the changed level signal generates a very weak electromagnetic signal near a lead according to an electromagnetic principle.
The non-contact detection probe is placed near a transmission line of a detected sensor of target equipment to receive extremely weak electromagnetic signals with specific frequency, if the extremely weak electromagnetic signals can be obtained, the detection is normal, otherwise, the detection is abnormal.
In addition, in the invention, the transmitting module adopts a pre-amplifying circuit and a frequency-selecting amplifying circuit which are preferably a high-impedance low-noise triode pre-amplifier, an LM324 and the like (without being limited to using an amplifying chip with the same characteristics), amplifies the received signal, performs frequency-selecting amplification, outputs the amplified signal and feeds the amplified signal back to the single chip for processing and judgment. The single chip microcomputer compares the input frequency-selecting amplified signals according to the counting of a counter (counting the number of pulses sending out signals and the number of received signals) of the single chip microcomputer, and outputs a judgment result.
Further, the single chip microcomputer is connected with a detection state selection switching module (for example, a state switching button is adopted) and is used for selecting to switch to use the receiving detection module or the transmitting module.
In addition, the timer of the single chip controls the emission detection probe to emit infrared light signals with fixed frequency in a timed mode to carry out emission detection work.

The design principle is that the extremely weak electromagnetic signal is detected by a detection probe, amplified by hundreds of thousands of times and frequency-selected, then the signal is transmitted to a single chip microcomputer to be discriminated by a logic judgment module, and finally a detection result is given.
When the device is used, the working states are alternated through the state switching button 4, wherein the singlechip is connected with the detection state indicator lamp 7 and used for indicating the working state of the current detection module, and the working state of the current device is realized by a logic judgment module connected with the singlechip and a state detection circuit module of a transmitting/receiving detection probe interface.
And in the working state A, the state indicator lamp is a receiving sensor for detecting the target equipment when being turned on, and otherwise, the state indicator lamp is a transmitting sensor for detecting the target equipment when being turned on. When in the working state a, only the transmitting/receiving probe installed at the transmitting/receiving detection probe interface 1 is used, and when in the working state 2, the non-contact detection probe installed at the non-contact detection probe interface 2 is also used, as shown in fig. 6.
