Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] Existing data transmission method, when testing, the traditional data flow inside the test equipment and the airborne suspension is as follows: figure 1 Shown:

[0024] The test equipment and the airborne hanging objects communicate with the task machine through the separation port 1 on the 1553B bus. Its basic working mode is that the test equipment sends commands to the task machine through the 1553B communication bus, and the task machine returns the status to the test equipment through the 1553B communication bus.

[0025] The mission machine and each subsystem perform signal cross-linking through the RS 422 communication bus 3; each subsystem sends its respective working status to the telemetry system in real time through the RS 422 communication bus 3; the telemetry system groups the data of each subsystem into telemetry data, and then It is se...

Abstract

The invention provides a transmission method for uploading airborne suspender test telemetry data. The transmission method comprises the steps that the telemetry data of multiple subsystems are sent to a task machine through an RS422 communication bus; the task machine and the test equipment send and receive data according to the communication period of the test communication protocol; and the task machine performs sub-address allocation and data length processing on the received telemetry data according to a test communication protocol, converts the telemetry data into a 1553B transmission format, and sends the telemetry data to test equipment through a 1553B communication bus.

Description

technical field [0001] The invention belongs to the field of testing of airborne suspended objects, and in particular relates to a transmission method for uploading test telemetry data of airborne suspended objects. Background technique [0002] As one of the means of daily maintenance, the test of airborne suspended objects is expected to have fewer test connecting cables, less equipment and short test time. And the development unit hopes to obtain as much test data of each subsystem as possible during the test, so as to facilitate the analysis of the working status of each subsystem. [0003] During the technical field test, the test equipment is only connected to the airborne suspension through the separation port, and according to the requirements of the national military standard, the separation port only has the communication function of 1553B bus, that is, the test equipment can only communicate with the task machine, and cannot communicate with other subsystems . T...
