Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for powering on an outdoor wireless Access Point (AP).
Background
The wireless APs may be divided into indoor wireless APs and outdoor wireless APs according to usage scenarios. The outdoor wireless AP is also called an outdoor wireless AP and is commonly used for outdoor wireless network deployment and construction. Outdoor wireless APs are typically mounted in a pole-clasping fashion at the height of a light pole, trunk, etc., and then when a mounting point is selected, a sturdy mounting point is selected. The installation point is required firmly, can not have the condition such as rock, simultaneously, also need keep away from facilities such as forceful electric power high-voltage line, fire control pipeline and building lightning rod as far as possible to avoid the interference of forceful electric power, strong magnetism.
The outdoor wireless AP power supply mode can be divided into: power Over Ethernet (POE), Direct Current (DC) adapter. In contrast, the DC adapter power supply needs to arrange a circuit to the outdoor AP separately, which is troublesome to operate and has a large risk; and POE power supply is relatively simple, easy to deploy and safe.
A complete POE system includes two parts, a Power Sourcing Equipment (PSE) terminal and a Power receiving Device (PD) terminal. The PSE is a device that supplies power to the ethernet client device and is also a manager of the entire POE ethernet power supply process. And the PD is the PSE load of accepting the power supply, the customer end equipment of POE system promptly, and outdoor wireless AP is PD equipment promptly, supplies power for outdoor wireless AP through the POE system then only need increase a PSE, and outdoor AP is as PD equipment, utilizes the net twine can realize the power supply to outdoor wireless AP.
In the current power supply of the PSE, two capacitors are used for Electromagnetic Compatibility (EMC) filtering, and interference of an input Alternating Current (AC)220V power supply end of the PSE is discharged to the ground through the capacitors. Generally speaking, without the PSE being grounded, the power ground is theoretically equipotential with the earth ground in the environment (PGND), but because of the two capacitive division filtering, the power ground of the PSE becomes AC 110V. Therefore, the AC220V power supply is AC110V with respect to power ground and AC220V with respect to PGND. In this case, there is a voltage difference between the casing of the PSE device and PGND, that is, an unequal potential between the ground of the PSE device and PGND; and outdoor wireless AP needs lightning protection measures, so that the outdoor wireless AP needs to be accessed to the ground PGND. This results in different reference planes for the grounds of the outdoor wireless AP and the PSE device.
Before the POE supplies power, the PSE and the PD reference level are required to be ensured to be on the same plane, and once a voltage difference exists between the PSE and the AP, POE detection failure can be caused, so that the AP cannot be powered on or the POE is powered on to forcibly supply power to the outdoor wireless AP in a strong power supply mode, and the outdoor AP is unstable.
