A multidrop network system includes N network devices. The N network devices include a master device and multiple slave devices, and each network device has an identification code as its own identification in the multidrop network system. The N network devices have N identification codes and obtain transmission opportunities in turn according to the N identification codes in each round of data transmission. Each network device performs a count operation to generate a current count value, and when the identification code of a network device is the same as the current count value, this network device obtains a transmission opportunity. After a device obtains the transmission opportunity, it determines whether a cut-in signal from another network device is observed in a front duration of a predetermined time slot, and then determines whether to abandon/defer the right to start transmitting in the remaining duration of the predetermined time slot.

Multidrop network system and network device

A multidrop network system includes N network devices. The N network devices includes M transmission-permissible devices including a master device and at least one slave device, wherein M is not greater than N. Each transmission-permissible device has at least one identification code as its identification in the multidrop network system, and the M transmission-permissible devices have at least N identification codes. The M transmission-permissible devices obtain transmission opportunities in turn according to their respective identification codes in each round of data transmission. A Kdevice among the M transmission-permissible devices has multiple identification codes, and thus obtains multiple transmission opportunities in one round of data transmission. Each of the M transmission-permissible devices performs a count operation and generates a current count value; and when the current count value is the same as the identification code of a device of the M transmission-permissible devices, this device earns one transmission opportunity.
