Description
Technical field
The present invention relates to a kind of controllers, are specifically realized to PD equipment timing power supplies based on low-frequency time-code Service of Timing
Controller.
Background technology
PD equipment is installed in often to be inconvenient to touch, and is inconvenient to the position safeguarded, such as wireless aps, the IP prisons of POE
Control camera, the POS of wall embedded type, humiture collection device of installation of ceiling etc..
And when PSE device (such as POE switch or routers of feeder ear) it is non-we can be transformed and enter from the background
When management, some troubles are brought to the PD equipment time controls work of dispersion to us, such as：
For time purpose that is energy saving or needing setting that need not work, we need timing to close the camera that POE powers
Power supply only wants to it in next period, such as evening 18:It just works after 00；
There is operation irregularity, when needing power-off restoration that could restore normal work, needs maintenance personnel and find simultaneously
It shows up, cable connection manually is disconnected to PD equipment, then reinsert cable and be attached to restore.
Wish that the phone simply to POE, the printer regulation working time configuration of the wireless routing AP, POE of POE are kept away
Exempt from these equipment, is abused on one's own time.
Thus needing us to be arranged between PSE device and PD equipment can be according to the control of our setting time power supplies
Device, we are referred to as " PD equipment timing controller ", but after we set the time on the timing controller of PD equipment, how
The accuracy of timekeeping of controller throughout has been installed/has been distributed in guarantee, is avoided the time deviation generated when walking for a long time accumulation, is
The difficulty that we encounter, the main object of the present invention are to realize a kind of timing controller for the PD equipment not needing artificial clock synchronization.
Existing technical solution one is the work(for needing the hardware and software of PSE device itself to be intended to support to provide time reference
Can, and need to know about this PSE device, while there are the personnel into the backstages PSE permission PD equipment timing controllers are arranged, from
PSE device obtains time reference, and the data service of last layer PSE device is LAN service, and user equipment cannot access interconnection
Net, cloud platform cannot realize remote control and maintenance function by the data connection of PSE device itself, support PD for fulgurite
The PSE device of reason is higher to the requested knowledge of operating personnel；Due to management etc., there is no upper one by PD user or maintenance personnel
The operation of layer PSE device and administration authority；When last layer PSE device is not the assets of PD user, PD user cannot access and control
System cannot obtain time reference by the last layer network of PSE.
For existing technical solution second is that using " POE middle power supplyings equipment ", its main function is not support POE to power
The network equipment and terminal between, increase the equipment of a power supply -48V, will not support device network that POE powers becomes can be with
Support the network of PD equipment, " POE middle power supplyings equipment " can not achieve period control, PD equipment that can not be external to each port
Correct time section control is carried out, the required electric power of POE equipment is only to provide.
Invention content
The purpose of the present invention is to provide being realized to the controllers of PD equipment timing power supplies based on low-frequency time-code Service of Timing,
To solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides the following technical solutions：
The controller to PD equipment timing power supplies is realized based on low-frequency time-code Service of Timing, including POE takes electric unit, time service
Long wave is received to be connected with microprocessor unit and relay group control unit, the time service long wave reception with microprocessor unit respectively
Meeting POE takes electric unit and relay group control unit, POE that electric unit is taken to be also respectively connected with relay group control unit and PSE friendships
Exchange device, relay group control unit are also connected with PD equipment.
Further technical solution as the present invention：The time service long wave is received passes through national time service with microprocessor unit
The time service platform at center obtains the standard time.
Further technical solution as the present invention：The POE takes electric unit by inputting Ethernet network interface from upper layer
PSE conversion equipments obtain working power.
Further technical solution as the present invention：The PD equipment include printer, IP cameras, IP phone and
WLANAP, movable attendance checking machine, optic communication lighting apparatus.
Compared with prior art, the beneficial effects of the invention are as follows：1. by this PD timed power-supplying controller, do not needing pair
In the case that PSE device is operated and configured, the work of PD equipment on demand on time may be implemented, and need not manually proofread
Time reference；
2.PD timed power-supplying controllers obtain power for operation from existing POE networks, it is not necessary in addition re-lay power cord；
3.PD timed power-supplying controllers receive low-frequency time-code self by long wave receiver, do not influence the data of PSE device
In addition business need not also be laid with the communications cable；
4.PD timed power-supplying controllers can make more PD controls of distributed single PD control or centralization on demand,
Such as in the 24 PD equipment connect at PSE, it is only necessary to carry out working time section control to 2 PD equipment therein, be conducive to section
The about cost of control program.
