According to understanding, typical search equipment delay is 30ms, and the time delay of dormancy activation is 15ms, and the time delay of vehicular equipment channel access is
15ms, it is very high to delay requirement due in Industry Control occasion, and Zigbee possesses the feature, and PLC FPGAs just
Controller does not just possess the short feature of time delay.
Fourth, network capacity is big:One Zigbee network of hub-and-spoke configuration can at most accommodate 254 secondary equipment and one
, can simultaneously there are most more than 100 Zigbee networks in main equipment, and composition between network can be with a network area
Flexibly set.
Fifth, reliability is high:Zigbee takes collision avoidance strategy, while to need the communication service of fixed-bandwidth pre-
Dedicated time slot has been stayed, the competition and conflict for sending data has been avoided.And media intervention key-course MAC employs fully validated number
According to transmission mode, any one packet for sending all has to wait for the confirmation of recipient.If going out during transmission
Existing problem, can also resend, and on the basis of simple structure, low cost, the characteristics of possess high reliability, and PLC can
Programmed logic controller, is that can just ensure reliability on the basis of cost is increased.
Sixth, safe:Zigbee provides the packet integrity checking function based on CRC, supports
Authentication and certification, and the AES of AES-128 is employed, each application is flexibly determined its security attribute, possess
Safe the characteristics of.
