Description
Technical field
The present invention relates to the data communication field, specifically, relate to a kind of system and method for remote startup control.
Background technology
The continuous growth of communication service demand requires communication apparatus to possess area coverage rate widely, and many terminal equipments just are installed in corridor or the open air near user side.Simultaneously, the user makes broadband access and networking mode become main flow to the demand of message transmission bandwidth, a large amount of access devices need be placed near the user side away from communication office station central machine room (be commonly referred to as local side in the industry, for simplicity, below all be called local side).The Remote Power Supply system utilizes twisted-pair feeder to come a kind of scheme to the power terminal equipment of far-end, can certainly adopt other far to power to the terminal equipment of far-end to coming for line, and the Remote Power Supply system comprises local supply, twisted-pair feeder and far end supply.At local side, the local supply of Remote Power Supply system is raised to (according to different requirements, the value of boosting is also different) behind the high pressure with this ground voltage, utilizes twisted-pair feeder that high pressure is sent to far-end, far-end carries out the DC/DC conversion by far end supply then, is converted into the far-end required voltage.Local side is the general preferred a kind of far-end power supply plan of industry by twisted-pair feeder for far-end provides the method for power supply, adopt Remote Power Supply, but improved the reliability and the ability of maintenance of far end supply, made the far-end power supply technique in increasing networking products, obtain to use.
Remote Power Supply international standard regulation, every pair far away all restricted to the power of transmission for line, far away from the right through-put power difference of line according to different demands to every pair, because usually need in actual use many to far away for line to jointly to the power supply of remote equipment, for security consideration, every pair of line that supplies far away is to all there being current limit function, promptly when remote equipment opens machine work, far away for line centering set up high pressure far away when not reaching the quantity of predetermined demand for the demand pairs amount, remote equipment will far exceed standard and cisco unity malfunction for the right electric current of line owing to flowing through.
At local supply and far end supply one to one the time, the time basically identical that local supply voltage is started working, can realize that far end supply opens machine simultaneously, yet, when local side power supply and far end supply one-to-many, the machine that the opens time demand difference of different far end supplies, and local supply can only be started working simultaneously, make the machine that the opens time unanimity of different far end supplies, can not satisfy the demand of the machine that the opens asynchronism(-nization) of different far end supplies.
Prior art provides a solution, local supply adopts a plurality of local supply modules in this scheme, far end supply also adopts a plurality of far end supply modules, each local supply module links to each other with a far end supply module by a pair of twisted-pair feeder, in actual applications, each local supply module also may link to each other with a far end supply module to twisted-pair feeder by many, make the local supply module corresponding one by one with the far end supply module, parallel operation between the local supply module, all local side power modules open machine work simultaneously, have guaranteed that the far end supply module powers on simultaneously.And for the situation of the corresponding a plurality of far end supplies of local supply, as shown in Figure 1, local supply has increased CPU and has controlled packet synchronization and open machine, the local supply module of a corresponding far end supply is divided into one group, the electricity order is sent/is descended in the CPU grouping, has satisfied the demand that different far end supplies open the machine asynchronism(-nization).
