Description

Technical Field

[0001] This utility model relates to the field of wireless communication technology, specifically to a passive power indicator device. Background Technology

[0002] When a communication radio is in operation, the operator can only determine whether there is power output through the panel indicators, but cannot determine the actual signal power output. To determine whether the transmitter has malfunctioned, there are usually three testing methods: first, use a power meter to test whether there is signal output; second, use a spectrum analyzer to test the radio signal; and third, use another radio to receive and test.

[0003] The above three methods have limited effectiveness and poor operability in practical use. The instruments are not portable and cannot be assigned to each terminal; when using wireless, there is no suitable standard antenna; and in case of failure, there is no other radio to assist in the testing.

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Please see Figure 1 A passive power indicator device includes a receiving antenna for receiving electromagnetic waves, the receiving antenna being connected to a voltage doubler rectifier module for rectifying induced current and amplifying voltage, the voltage doubler rectifier module being connected to a control module for output control, and the control module being connected to a display module for outputting results.

[0025] In practical applications, when the radio is transmitting, the output signal is captured by the receiving antenna of the device, generating an induced current. The AC induced current is amplified by the voltage doubler rectifier module and rectified to output a doubled DC signal. The control module controls the display module to display the signal based on the received signal strength, thereby quickly and intuitively presenting the actual signal output and power range of the radio. This invention can quickly and intuitively present the actual signal output and power range of the radio, avoiding the use of large instruments and meters, and effectively improving applicability.

[0026] Please see Figure 1 and Figure 2The voltage doubler rectifier module includes a first diode D1 whose anode is connected to one end of the receiving antenna. The cathode of the first diode D1 is connected to a first capacitor C1 and a second diode D2. The first capacitor C1 is connected to the other end of the receiving antenna. The anode of the second diode D2 is connected to the first diode D1, and the cathode of the second diode D2 is connected to the control module.

[0027] In this embodiment, during the positive half-cycle of the induced current generated by the receiving antenna, the first diode D1 is turned on and the second diode D2 is turned off, and the induced current charges the first capacitor C1 through the first diode D1; during the negative half-cycle of the induced current, the first diode is turned off and the second diode D2 is turned on, and the induced current outputs the negative half-cycle peak voltage through the second diode D2, while the first capacitor C1 discharges, thereby enabling the voltage doubler rectifier module to output a DC signal with twice the peak voltage of the induced current to the control module.

[0028] Please see Figure 1 and Figure 2 The control module includes a third diode D3 and a fourth diode D4 connected in series at one end of the cathode of the second diode D2. The anode of the fourth diode D4 is connected to the cathode of the third diode D3. Both the third diode D3 and the fourth diode D4 are connected to the display module.

[0029] In this embodiment, when the voltage output by the second diode D2 reaches the sum of the driving voltage of the display module connected to the cathode of the third diode D3 and the forward voltage drop of the third diode D3, but does not reach the sum of the forward voltage drops of the third diode D3 and the fourth diode D4 and the driving voltage of the display module connected to the cathodes of the third diode D3 and the fourth diode D4, the display module connected to the cathode of the third diode D3 outputs a display; when the voltage output by the second diode D2 reaches the sum of the forward voltage drops of the third diode D3 and the fourth diode D4 and the driving voltage of the display modules connected to the cathodes of the third diode D3 and the fourth diode D4 respectively, the display modules connected to the cathodes of the third diode D3 and the fourth diode D4 respectively output a display; thereby realizing the control module to control the display module to display according to the received signal strength.

[0030] Please see Figure 1 and Figure 2 The display module includes a first light-emitting diode LED1 whose anode is connected to the anode of the third diode D3, a second light-emitting diode LED2 whose anode is connected to the cathode of the third diode D3, and a third light-emitting diode LED3 whose anode is connected to the cathode of the fourth diode D4. The cathodes of the first light-emitting diode LED1, the second light-emitting diode LED2, and the third light-emitting diode LED3 are all connected to the anode of the first diode D1.

[0031] In this embodiment, if the voltage output by the second diode D2 satisfies the driving voltage of the first light-emitting diode LED1, then the first light-emitting diode LED1 is lit.

[0032] If the voltage output by the second diode D2 satisfies the sum of the forward voltage drop of the third diode D3 and the driving voltage of the second light-emitting diode LED2, then both the first light-emitting diode LED1 and the second light-emitting diode LED2 will be lit.

[0033] If the voltage output of the second diode D2 satisfies the sum of the forward voltage drop of the third diode D3 and the fourth diode D4 and the driving voltage of the second light-emitting diode LED2 and the third light-emitting diode LED3, then the first light-emitting diode LED1, the second light-emitting diode LED2 and the third light-emitting diode LED3 will all be lit.

[0034] In other words, when the radio is transmitting, the stronger the signal it emits, the stronger the signal it receives, and the stronger the induced current generated by the receiving antenna. In this way, the voltage output by the second diode D2 will be stronger, and the more LEDs will be lit. This allows for a quick and intuitive presentation of the radio's actual signal output and power range.

[0035] Please see Figure 1 and Figure 2 Each of the first light-emitting diode LED1, the second light-emitting diode LED2, and the third light-emitting diode LED3 is connected in parallel with a protective capacitor.

[0036] In this embodiment, when the first LED1, the second LED2, or the third LED3 is lit, the corresponding parallel protection capacitors C2, C3, and C4 are charged. When the voltage doubler rectifier module outputs a large current, the protection capacitors, as a primary load, will charge first to lower the voltage, thus protecting the LEDs. When the transmitter instantly emits power, the protection capacitors are charged. When there is no current in the circuit, the protection capacitors discharge, causing the LEDs to turn off after a delay, thus displaying a delay effect and presenting the actual signal output and power range of the transmitter source more clearly and intuitively.

[0037] Please see Figure 1 A voltage amplifier circuit for amplifying the output voltage is connected between the voltage doubler rectifier module and the control module.

[0038] In this embodiment, the voltage output from the voltage doubler rectifier module is amplified by the voltage amplification circuit and then output to the control module, which can effectively increase the detection distance between the device and the transmitter.

[0039] Please see Figures 2 to 4The receiving antenna includes a first coil and a second coil arranged symmetrically. The first coil and the second coil have the same shape, both being spiral conical, and the smaller ends of the first coil and the second coil are arranged close to each other.

[0040] In this embodiment, the electromagnetic wave is generated by alternating electric and magnetic fields and propagates forward. The electric field drives the movement of free electrons inside the antenna, generating an induced current. Please refer to [link to previous text]. Figures 2 to 4 The A1 end of the first coil and the B1 end of the second coil serve as one end of the receiving antenna, and the B2 end of the first coil and the A2 end of the second coil serve as the other end of the receiving antenna. The first and second coils, both spirally conical, form a parabolic surface. The parabolic antenna can focus electromagnetic wave signals from space to a single point, thereby improving the sensitivity of signal reception. Furthermore, the first and second coils can receive electromagnetic waves from different directions, further enhancing the sensitivity of signal reception.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
