Embodiment Construction

[0028] refer to figure 1 , is a block diagram of a portable short-wave automatic test device of the present invention; wherein the portable short-wave automatic test device includes: a power management module, a control board, a FLSAH module, a key unit, a transceiver, an automatic antenna coordinator and a display, the Said control board contains FPGA module and ARM module; figure 1 The reason why the transceiver and the automatic antenna coordinator are all drawn as dashed boxes is because strictly speaking, the portable short-wave automatic test device does not include the transceiver and the automatic antenna coordinator, that is, it is regarded as a black box and the device of the present invention To interact, just receive the transceiver port data sent by the transceiver.

[0029] The ARM module includes a first bidirectional end, a second bidirectional end, a first input end, and a first output end, the FPGA module includes a third bidirectional end, a fourth bidirect...

Abstract

The invention discloses a portable short wave automatic test device. A FLSAH module is used to enable an FPGA module and an ARM module to work normally. A key unit is used to set a number of keys in advance, and at least comprises a frequency interval selection key, a time interval selection key, a start key and a pause key. The FPGA module is used to acquire the corresponding key value when the key unit is pressed. The ARM module controls a display to display the display content corresponding to the key value. After the key unit carries out a key start operation, the FPGA acquires the start key. After the ARM module recognizes the key value corresponding to the start key, the display is controlled to periodically display the frequency in frequency intervals. An automatic antenna coordinator is used to acquire a tuning result. A transceiver is used to set protocol communication data in advance and acquire protocol communication data. The ARM module is used to control the display to display the tuning result of the corresponding frequency according to the protocol communication data.

Description

technical field [0001] The invention belongs to the technical field of electronic applications, and in particular relates to a portable short-wave automatic test device, which is suitable for high-efficiency full-frequency band testing of main indicators of radio stations. Background technique [0002] When the short-wave radio station is debugged in the factory, when testing indicators, matching tests and electromagnetic compatibility tests, the test frequency point is about 2MHz. When testing at the airport, the test frequency points cover the entire shortwave band, and the workload of manual operation is quite large, and it is also prone to errors. [0003] The existing short-wave radio test equipment cannot be used for old products, and the cost is high and the volume is large, so it is not suitable for on-board testing and troubleshooting in the field. Contents of the invention [0004] For the problems existing in the above-mentioned prior art, the purpose of the pr...
