And step 33, when the current value output by the Beidou shipborne terminal under the condition that the value of the loaded second voltage is reduced is zero, determining the current voltage value loaded on the shipborne terminal as an undervoltage protection threshold value.
For example, the value of the second voltage is controlled to gradually decrease from 12V in step 31, in the process, the magnitude of the current value output by the Beidou shipborne terminal is checked at regular time, when the current value output by the Beidou shipborne terminal is zero, the value of the voltage loaded on the Beidou shipborne terminal is detected by using a universal meter, and the voltage value is determined as the undervoltage protection threshold value.

For example, the second preset initial value may be 36V, and when the value of the third voltage applied to the beidou shipborne terminal by the dc regulated power supply is 36V, the current value output by the beidou shipborne terminal should be 80mA, that is, the first current value is 80 mA.
And 42, controlling to increase the value of the third voltage, and acquiring a current value output by the Beidou ship-mounted terminal under the condition that the value of the loaded third voltage is increased.
And 43, when the current value output by the Beidou ship-mounted terminal under the condition that the value of the loaded third voltage is increased is zero, determining the current voltage value loaded on the ship-mounted terminal as an overvoltage protection threshold value.
For example, the value of the third voltage is controlled to gradually increase from 36V in step 41, in the process, the magnitude of the current value output by the beidou shipborne terminal is checked at regular time, when the current value output by the beidou shipborne terminal is zero, the value of the voltage loaded on the beidou shipborne terminal is detected by using a universal meter, and the voltage value is determined as the overvoltage protection threshold value.
And step 44, controlling to reduce the value of the third voltage, and acquiring a current value output by the Beidou ship-mounted terminal under the condition that the value of the loaded third voltage is reduced.
And step 45, when the current value output by the Beidou onboard terminal under the condition that the value of the loaded third voltage is reduced is equal to the second current value, determining the current voltage value loaded on the onboard terminal as overvoltage protection recovery voltage.
After the overvoltage protection threshold value is obtained in the step 43, the value of the third voltage is controlled to be gradually reduced, in the process, the magnitude of the current value output by the Beidou shipborne terminal is checked at regular time, when the current value output by the Beidou shipborne terminal is recovered to 80mA in the step 41, the value of the voltage loaded at the two ends of the Beidou shipborne terminal is detected by using a universal meter, and the voltage value is determined to be the overvoltage protection recovery voltage.
According to the electrical performance detection method of the Beidou onboard terminal, the value of the third voltage loaded on the Beidou onboard terminal is adjusted, and meanwhile the magnitude of the current value output by the Beidou onboard terminal is checked at regular time, so that the overvoltage protection threshold value and the overvoltage protection recovery voltage can be obtained.

The surge signal is used for simulating influence of sea waves on power adaptability of the Beidou shipborne terminal in the navigation process.
And step 53, after the first preset time, controlling the surge generator to stop inputting the surge signal to the Beidou shipborne terminal.
The length of the first preset time can be set according to the requirement of the user, for example, the first preset time can be set to 1 minute.
And step 54, judging whether the RNSS positioning function and the RDSS receiving function are normal.
If the RNSS positioning function and the RDSS receiving function are both normal, the Beidou shipborne terminal is considered to be slightly influenced by sea waves, and if one of the RNSS positioning function and the RDSS receiving function is abnormal, the Beidou shipborne terminal is considered to be greatly influenced by the sea waves, so that the surge interference resistance of the Beidou shipborne terminal needs to be enhanced.

the initial value of the fifth voltage can be set according to user requirements, and the initial value of the fifth voltage needs to be larger than a voltage value loaded on the Beidou shipborne terminal when the Beidou shipborne terminal normally works. For example, the initial value of the fifth voltage may be set to 70V.
And step 56, after a second preset time, adjusting the value of the fifth voltage to a preset value, and judging whether the RNSS positioning function and the RDSS receiving function are normal.
The length of the second preset time can be set according to the requirement of the user, for example, the first preset time can be set to 1 minute.
The preset value is a voltage value loaded on the Beidou shipborne terminal when the Beidou shipborne terminal works normally, and for example, the preset value can be 24V.
If the RNSS positioning function and the RDSS receiving function are both normal, the Beidou shipborne terminal is considered to have the protection capability of positive and negative reverse connection, and if one of the RNSS positioning function and the RDSS receiving function is abnormal, the Beidou shipborne terminal is considered to have no protection capability of positive and negative reverse connection.

According to the electrical performance detection method of the Beidou shipborne terminal, the surge generator is controlled to input the surge signal into the Beidou shipborne terminal, and then whether the RNSS positioning function and the RDSS receiving function are normal or not is judged, so that whether the Beidou shipborne terminal has the surge interference resistance or not can be detected. Meanwhile, after the voltage loaded on the Beidou shipborne terminal is a normal value from an initial value, whether the RNSS positioning function and the RDSS receiving function are normal or not is detected, and whether the Beidou shipborne terminal has the protection capability of positive and negative reverse connection or not is detected.
