The simulation beam scheduling control platform realizes the simulation beam scheduling function by the cooperation of the radio frequency signal, the clock pulse, the beam control information and the mode switching signal provided by the cable access base station through the data processing module, the clock module and the control module in the main control board 2, wherein the mode switching signal is matched according to different radio frequency switches 3, the abnormal alarm module is arranged in the main control board 2, the alarm device can be started through the abnormal alarm module, the key operation information of the system can be monitored in real time, and when the abnormal condition occurs, the recording and the alarm are carried out.

The signal attenuator 4 is used for simulating signal attenuation at different distances to support a platform to perform long-distance service simulation test, and the platform adopts a fixed attenuation and step attenuation combination scheme to flexibly simulate signal attenuation conditions at different distances.
Specifically, the system in this embodiment includes a serial port interrupt, external interrupt, and timer interrupt operation module, and implements a corresponding terminal and a timing process through a corresponding interrupt service subroutine. The system is accessed to beam switching information issued by a base station through a 232-serial port, and a serial port interruption module is responsible for receiving and analyzing data and storing the analyzed data into a beam direction table; meanwhile, the timer generates 1ms timing interruption and is calibrated and synchronized with an externally accessed base station 10ms pulse signal, and then when the timer interruption module is started, the level state of a GPIO port connected with the radio frequency switch is controlled according to the beam direction table, so that beam direction switching is realized; in addition, the system judges whether the program is abnormal or not by monitoring the time from the start of timing by the timer to the completion of data receiving, and lights a red LED lamp and gives an alarm by a buzzer if the program is abnormal. Specifically, the system also comprises the following functional modules and a data processing module: the serial port receives and analyzes the wave beam control data frame of the base station; a clock module: the internal timer is synchronous with an external clock and generates a 1ms timing signal; a control module: the single-pole multi-throw radio frequency switch controls the beam direction switching according to the level state of the accessed IO port; an abnormality alarm module: a data processing timeout warning; a remote simulation module: and simulating the attenuation conditions of signals at different distances.
The feasible method for synchronous calibration adopts the following mode that an external 10ms pulse signal is connected to an edge detection pin of a chip, the edge transition situation of the 10ms pulse is monitored, if the detected edge is a rising edge, a rising edge interrupt event is entered, namely, a 10ms timer is initialized and started, the starting count Time _ CNT value of the 1ms timer is initialized to Nt (t is a natural number greater than 0 and represents the repeated execution times, wherein N1 is equal to 0) through the interruption of the 10ms timer, the 1ms timer is started, and the high level and the low level of the GPIO output pin are switched in the 1ms timer. And if the chip detects the 10 millisecond pulse falling edge, triggering the falling edge event of the edge detection interrupt, and reading the Time _ CNT value Qt corresponding to the current 1 millisecond clock. If Qt is equal to 0, then synchronization is completed; if Qt ≠ 0, the next 1-millisecond timer start count value Nt +1 ═ Nt + M-Qt; and simultaneously, the 10 millisecond pulse and the GPIO pin signal are connected into an oscilloscope to check the waveform synchronization condition of the 10 millisecond pulse and the GPIO pin signal. By the self-calibration synchronization method, the final synchronization error of the waveforms can be checked within 40 nanoseconds by an oscilloscope.
In the operation process, the radio frequency signal is transmitted to the signal attenuator, the attenuated signal passes through the radio frequency switch and then controls the radio frequency switch to switch and point, and the control of the radio frequency switch is also adjusted according to the adjustment result of the timer and the mode switching processing result. The clock pulse sent by the base station starts a timer through a clock module, and when the timer interruption module is started, the level state of a GPIO port connected with the radio frequency switch is controlled according to the beam direction table, so that the beam direction switching is realized.
