Title:
信号伝送システム
Document Type and Number:
Japanese Patent JP7351248
Kind Code:
B2
Abstract:
To enable the acquisition of tolerance to a noise influence, an influence due to a pulse width distortion, etc., so as to make it easy to exhibit transfer performance.SOLUTION: Among bus connectors 11 to 13 of a system bus 10 of a base board, the token frame transmission side of the bus connector 13 located on the most downstream side is connected to the token frame reception side of the bus connector 11 located on the most upstream side through a bypass transmission route C11. A most upstream side signal transmission circuit, which is located at the most upstream side in the base board system bus 10, starts to transmit the (N+1)-th token frame when receiving the N-th token frame through the bypass transmission route C11. A transmission buffer 14 sets a total time obtained by summing each token frame transmission time of each signal transmission circuit 11-13, as a threshold Th1, so as to control in a manner to approximate the token frame transmission time of a basic side transmission buffer 14 to the threshold Th1 in a range smaller than and including the threshold Th1.SELECTED DRAWING: Figure 1
