The antenna connection port 1 is used for connecting the antenna 20 to be detected, and the satellite navigation antenna detection device 10 can be used for setting a plurality of antenna connection ports 1 to simultaneously detect a plurality of antennas 20 to be detected, so that the detection efficiency is improved. In one practical application, the antenna connection port 1 may be a radio frequency connector port.
The acquisition and detection circuit 2 is configured to acquire an electrical signal output by the antenna 20 to be detected through the antenna connection port 1, and output the electrical signal to the control module 3. The electrical signal may be a working current of the antenna 20 to be detected, each acquisition and detection circuit 2 may be disposed corresponding to one antenna connection port 1, and at least the working current of the antenna 20 to be detected is directly acquired or equivalently acquired, for example, equivalently acquired by means of acquiring a voltage of the sampling resistor 202. The electrical signal may also be the operating frequency or power of the antenna 20 to be detected, and a corresponding acquisition and detection circuit is adopted according to the type of detection required in practice.
The control module 3 is configured to determine whether the magnitude of the electrical signal exceeds a preset standard range, so as to generate a detection result and output the detection result to the display module 4. For example, the control module 3 may include an MCU chip, a register of the MCU chip may register data corresponding to a preset standard range, such as an upper limit value and a lower limit value, and after receiving the electrical signal input by the acquisition and detection circuit 2, the comparator of the MCU chip may be used to compare the upper limit value with the lower limit value, so as to determine whether the electrical signal is normal, and the MCU chip may adopt a macrocrystalline STC8F2K16S2 model chip.

By using the gating module 7 and the external power supply port 6, the electric energy of an external power supply (such as the mobile power supply 30) is obtained through the external power supply port 6, and is used for supplying power to a back-end device, which may be a receiver or other device for signal processing.
The gating module 7 may include at least one relay for turning on or off the external power supply port 6 and the power supply interface 8 when triggered by the detection result. At least one relay forms a gating circuit, and the gating of the circuit is realized under the triggering of the control module 3. The gating module 7 may also be implemented by a manual switch, and the display module 4 is used to determine whether the working current of the antenna 20 to be tested is normal, and when the working current is determined to be normal, the external power supply port 6 is connected to the mobile power supply 30 by operating the manual switch. As shown in fig. 2, the output voltage of the external power supply port 6 can be detected by a detection tool such as a multimeter 40, and the output voltage is ensured to meet the power supply requirement of the back-end device.
In one possible implementation, as shown in fig. 5, the acquisition and detection circuit 2 may include an analog-to-digital converter 201 and a sampling resistor 202; the sampling resistor 202 is used for being connected with the antenna 20 to be tested in series; the analog-to-digital converter 201 collects the voltage of the sampling resistor 202, and is configured to convert the voltage of the sampling resistor 202 into a digital signal and output the digital signal to the control module 3, where the voltage of the sampling resistor 202 is used to reflect the working current of the antenna 20 to be tested. Since the analog-to-digital converter 201 needs to input a voltage value for conversion, the current value cannot be directly converted, and after sampling the working current of the antenna through the sampling resistor 202 with a standard resistance value, the analog-to-digital converter 201 performs analog-to-digital conversion on the voltage at two ends of the sampling resistor 202 to obtain a digital signal corresponding to the voltage of the sampling resistor 202. The digital signal can be output to the control module 3 for calculation or processing, and the control module 3 judges whether the working current of the antenna is abnormal or not.
