Abstract

POE equipment power gathers and wisdom management system based on distributing type, PC passes through the net twine and connects the POE switch, the POE switch passes through net twine linkage unit and monitors always to control, the unit passes through net twine and connects PD, through the resistance of cluster in POE equipment power supply line, convert the required electric current of POE equipment into voltage, through analog-to-digital conversion, calculate the current value of POE equipment under the current state, and calculate the actual consumption of current POE equipment or directly obtain the consumption of POE equipment with the voltage value of gathering together, then compare with actual consumption again, in case the consumption of POE equipment exceeds the time limit with the deviation of normal consumption + -20%, think that POE equipment has been in abnormal state promptly, the microcontroller who is responsible for the control at this moment breaks off the power supply of POE equipment promptly, force it. At present, no such products exist in the market, so that the POE fault problem is mostly treated in the actual use by a manual intervention mode. Therefore, compared with manual intervention, the method has the characteristics of intelligence and timeliness, and reduces the labor cost.

Description

Distributed POE equipment power acquisition and intelligent management system

Technical Field

The invention relates to the field of POE equipment management systems, in particular to a distributed POE equipment power acquisition and intelligent management system.

Background

With the development of ethernet technology and the promulgation of the IEEE 802.3af standard, more and more POE devices are emerging in our lives. Taking video surveillance (POE monitoring equipment) as an example, in a large enterprise, hundreds, even thousands of devices are needed if video surveillance is to be installed to monitor every corner of the enterprise. So numerous POE equipment, its quantity that breaks down also increases thereupon, and the simple personnel that rely on manage, not only occupy a large amount of manpower resources, but also can cause manpower resources's waste (POE can both normally work under the majority condition, and it breaks down unpredictably, needs personnel to pay close attention to in real time again).

At present, aiming at the problem of faults of POE equipment in the using process, the POE equipment is restarted by mostly adopting an operation method of manual power-off of personnel. The method not only wastes more manpower and material resources (because large POE equipment is arranged at high places outdoors), but also cannot find the POE equipment in the first time. Therefore, some unnecessary troubles are brought to the popularization and the use of the POE equipment.

Disclosure of Invention

In order to overcome the defects in the prior art, the invention provides a distributed POE equipment power acquisition and intelligent management system, which judges whether POE equipment normally works or not by monitoring power parameters (power, voltage and current) of the POE equipment, and once the POE equipment is abnormal, the equipment is forced to restart in a short time (millisecond level), so that the POE equipment intelligently operates, and the state of the POE can be recorded in real time to provide data support for tracking afterwards.

In order to achieve the purpose of the invention, the invention adopts the technical scheme that:

POE equipment power gathers and wisdom management system based on distributing type, PC passes through the net twine and connects the POE switch, the POE switch passes through net twine linkage unit and monitors always to control, the unit passes through net twine and connects PD, through the resistance of cluster in POE equipment power supply line, convert the required electric current of POE equipment into voltage, through analog-to-digital conversion, calculate the current value of POE equipment under the current state, and calculate the actual consumption of current POE equipment or directly obtain the consumption of POE equipment with the voltage value of gathering together, then compare with actual consumption again, in case the consumption of POE equipment exceeds the time limit with the deviation of normal consumption + -20%, think that POE equipment has been in abnormal state promptly, the microcontroller who is responsible for the control at this moment breaks off the power supply of POE equipment promptly, force it.

Further, the unit and the monitoring master controller are respectively power acquisition and intelligent management equipment of the POE equipment; the PD is POE equipment; the POE switch is a POE power supply.

The invention has the beneficial effects that:

it judges whether POE equipment normally works through the power parameter (power, voltage and the electric current) of monitoring POE equipment, in case appear unusually, equipment restarts in will very short time (millisecond level) by force to make POE equipment wisdom operation, and the state that can real-time recording POE tracks provides data support for the affairs later. At present, no such products exist in the market, so that the POE fault problem is mostly treated in the actual use by a manual intervention mode. Therefore, compared with manual intervention, the method has the characteristics of intelligence and timeliness, and reduces the labor cost.

Detailed Description

In order to make the content of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

As shown in fig. 1, POE device power collection and intelligent management system based on distributing type, the PC passes through the net twine and connects the POE switch, the POE switch passes through net twine linkage unit and monitors always to control, the unit passes through net twine and connects PD, through the resistance of cluster in POE device power supply line, convert the required electric current of POE device into voltage, through analog-to-digital conversion, calculate the current value of POE device under the current state, and calculate the actual consumption of current POE device or directly obtain the consumption of POE device together with the voltage value of gathering, then compare with actual consumption, in case the consumption of POE device is when exceeding with the deviation of normal consumption + -20%, think that POE device has been in abnormal state promptly, the microcontroller who is responsible for the control at this moment breaks off the power supply of POE device promptly, force its restart.

The unit and the monitoring master controller are respectively power acquisition and intelligent management equipment of POE equipment; the PD is POE equipment; the POE switch is a POE power supply.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
