Embodiment
Be illustrated in figure 3 as the present invention to the monitoring module schematic diagram of powering, solid line among the figure is represented power planes, as can be seen from the figure, a kind of communication equipment involved in the present invention comprises: main control board (or service processing board), slave control board (or service processing board), several do not have the monitoring module and the device power supply (DPS) of voltage transformation module; On described each master control borad (or service processing board), all be provided with a DC-to-DC voltage modular converter, the input of described voltage transformation module by backboard with provide-the galvanic device power supply (DPS) of 48V links to each other, after voltage transitions, its output is connected with the power interface of its place master control borad, the output of each voltage transformation module also links to each other with the positive pole of an isolating diode respectively simultaneously, and the negative pole of described isolating diode is connected a bit by backboard; The power interface of described each monitoring module links to each other with described tie point.All be provided with detection module in described each monitoring module, shown in chain-dotted line among Fig. 3, it can link to each other with the output of described each voltage transformation module, and whether the output voltage that is used to detect voltage transformation module is normal.
Utilize above-mentioned communication equipment, the present invention also provides the method for supplying power to of monitoring module in a kind of communication equipment.Be illustrated in figure 4 as the flow chart of steps that the present invention gives the monitoring module method of supplying power to, and in conjunction with Fig. 3, have two master control borads (or service processing board) with communication equipment, isolating components and parts is that isolating diode is an example, describes the concrete steps of this method:
At first, be arranged on the main control board voltage transformation module with device power supply (DPS) provide-the 48V voltage transitions becomes the operating voltage of described master control borad, and exports to main control board; Because the operating voltage of described master control borad is identical with the operating voltage of the monitoring module that does not have voltage transformation module, so extract this output voltage within the operating voltage range of described monitoring module; In like manner extract voltage through the conversion of the voltage transformation module on slave control board back output.
Secondly, the output voltage of the voltage transformation module on the main control board that extracts is carried out voltage isolation through an isolating diode, in like manner the output voltage of the voltage transformation module on the slave control board is isolated; Voltage after again two-way being isolated closes the road by backboard and handles, and obtains one the tunnel and closes road voltage.The described purpose that the output voltage of voltage transformation module is isolated is owing to need close the road processing to the voltage that extracts on two master control borads, cause that voltage pours in down a chimney when directly on backboard, connecting, so the output voltage of each road voltage transformation module is isolated closing Lu Qianxian for the output voltage of the voltage transformation module that prevents to be provided with on two master control borads.Because the operating voltage of described master control borad is identical with the operating voltage of the monitoring module that does not have voltage transformation module, can directly utilize, so should reduce to give the voltage drop that causes in the process of described monitoring module power supply as far as possible at the output voltage that extracts voltage transformation module; But isolating diode is that certain pressure drop is arranged, so the output voltage of the voltage transformation module that is provided with on two master control borads will inevitably cause certain voltage drop through behind the isolating diode, so need select the little isolating diode of conduction voltage drop for use.Though the output of the voltage transformation module that the present invention is provided with from master control borad is drawn the operating voltage of described monitoring module, but can the operating voltage of master control borad not impacted, this is because the monitoring module general circuit design is fairly simple, usually power is very little, be no more than 3W, so only needing to tell very little part from the power of voltage transformation module output powers to monitoring module, so this method can not influence the master control borad operate as normal, also need not to the voltage transformation module that is provided with on master control borad type selecting (promptly selecting the module of bigger power output for use) again, so can not increase the cost of master control borad power unit.
At last, the described road voltage that closes is outputed to each and do not have the monitoring module of voltage transformation module, make it can operate as normal.
The present invention is by isolating the output voltage of the voltage transformation module on two master control borads and closing the road and handle the back to described monitoring module power supply, it is the 1+1 backup that this method of supplying power to provides power supply, the voltage transformation module that is provided with on one of them master control borad lost efficacy, the voltage transformation module that is provided with on another master control borad can not be affected, still can power by the described monitoring module of bio-occlusion, so just improved the reliability of giving described monitoring module power supply.Simultaneously also save the voltage transformation module that is provided with in the monitoring module in the prior art, reduced cost.
For when the voltage transformation module that is provided with on the master control borad lost efficacy, can in time find and overhaul, thereby further improve the reliability of giving described monitoring module power supply, the present invention has also done further improvement.
Whether at first, extract the output voltage of the voltage transformation module that is provided with on each master control borad, it is normal to be used to detect voltage transformation module output.
Secondly, the voltage that extracts is outputed to arbitrary, perhaps a plurality of monitoring modules detect, and alarm when testing result is unusual.Why be to give monitoring module to detect, rather than detect by master control borad oneself, be because when voltage transformation module lost efficacy, the master control borad at its place may operate as normal, and owing to the power supply of monitoring module backs up, unaffected so work, as long as therefore there is the voltage transformation module that is provided with on the master control borad not lose efficacy, monitoring module just can detect the voltage transformation module of inefficacy.
