AI Technical Summary

Technical Problem

The traditional RDSS communication device does not self-test the communication link that sends information, and it is impossible to determine whether the RDSS communication link is faultless every time the signal is sent, resulting in the inability to ensure the integrity of the signal transmission.

Method used

Through a closed-loop monitoring method for RDSS short message sending, combining software and hardware, the original data to be sent are obtained and packaged into short messages, the transmission time is determined, and the time interval and feedback signal are recorded by monitoring the enable pulses and current values ​​in the Beidou RDSS module, and the difference is calculated to determine the fault and the transmission is successful.

Benefits of technology

Real-time monitoring of the short message sending link sent by RDSS is realized, fault detection efficiency is improved, closed-loop detection of short message sending is completed, and data transmission reliability is improved.

Abstract

The present application discloses a closed-loop monitoring method, device and storage medium for sending RDSS short messages, which relates to the technical field of short message monitoring and solves the problem of RDSS communication link detection. The method includes obtaining raw data, encapsulating the raw data in the CPU, determining the waiting time to be sent according to the data length of the short message; sending a short message to trigger the monitoring of the enable pulse in the Beidou RDSS module, and the CPU records the time interval between the rising edge and the falling edge to determine the monitoring time interval; the rising edge triggers the multiplexer, the current value is greater than the current threshold, the multiplexer sends a short message, and the falling edge multiplexer does not send a short message; the CPU records the time interval between the high level and the low level and the difference between the waiting time to be sent, and compares it with the preset threshold to determine whether a fault occurs, and realizes the combination of software and hardware, and can monitor the short message sending link sent by RDSS in real time, improve the efficiency of fault detection, complete the closed-loop detection of short message sending, and improve the reliability of data transmission.
