specific Embodiment approach 1
[0032] Embodiment 1: Combining figure 1 Illustrating this embodiment, a control system for a matrix switch supporting four working modes of the present invention further includes a switch switching command packaging unit 1, a switch switching command buffer 2, a register group 3, a switch switching command control unit 4, switch switching command execution unit 5 and bus interface 6;
[0033] The matrix switch is a relay array with N rows and M columns;
[0034] The matrix switch switching command signal output terminal of the bus interface 6 is connected with the matrix switching switching command signal input terminal of the switching switching command packing unit 1, and the packing switching switching command signal output terminal of the switching switching command packing unit 1 is connected to the switch switching command buffer 2. Matrix switch command signal input terminal;
[0035] The switch switching command buffer 2 is a first-in-first-out memory with a depth of...
specific Embodiment approach 2
[0043] Specific embodiment 2: This embodiment is a matrix switch control method based on the control system of the matrix switch supporting four working modes, the process of the matrix switch control method includes two threads, and the two threads are executed in parallel , the two threads are:
[0044] First thread:
[0045] The switch switching command packaging unit 1 detects and reads the matrix switch command signal sent by the bus interface 6, and packs the matrix switch command signal and sends it to the switch switching command buffer 2,
[0046] Register group 3 stores and updates the number of switch commands stored in switch switching command buffer 2 in real time, and reads the number of switch commands stored in switch switching command buffer 2 stored in register group 3 through bus interface 6 , when the number of the switch commands is equal to 2N, stop sending the matrix switch command signal to the bus interface 6, and N is a positive integer;
[0047] Se...
specific Embodiment approach 3
[0052] Embodiment 3: The difference between this embodiment and Embodiment 1 is that when the working mode in the working mode signal is the immediate execution mode, the switch switching command control unit 4 controls the switch switching command execution unit 5 to control the matrix switch to execute corresponding actions The process is as follows:
[0053] The switch switching command control unit 4 reads all the command signals in the switch switching command buffer 2 one by one, and sequentially sends them to the switch switching command execution unit 5 to execute the corresponding commands, until all the command signals in the switch switching command buffer 2 are executed. until finished.
