Abstract
The invention discloses a method for achieving DC power supplying of an IP dispatching telephone through an Ethernet cable. According to the method, a junction box is utilized, a DC power source is connected into a fourth core, a fifth core, a seventh core and an eighth core of the Ethernet cable, and therefore power can be directly supplied to the IP dispatching telephone through the Ethernet cable, wherein the fourth core, the fifth core, the seventh core and the eighth core are idle. Through the method, installation and power management of the IP dispatching telephone are optimized, installation time is shortened, the application reliability of the telephone is improved, and the operation and maintenance costs of equipment are greatly reduced.
Description
Technical field
The present invention relates to ethernet technology field, particularly relate to one and utilize Ethernet netting twine to realize IP dispatching telephone direct current supply method.
Background technology
At present, the transformer station of newly-built and reorganization and expansion, generally to use IP dispatching telephone, replaces original traditional voice telephony.The application of IP dispatching telephone, except needs center IP scheduling switch and networking passage, also will carry out signal transmission for IP dispatcher telephone by netting twine and interface.Ensure its reliable communication, just need to realize reliable power supply, because rural power grids transformer station etc. just cannot ensure that phone obtains POE and powers in area far away.So IP dispatching telephone is usually placed in the master station of transformer station's night shift room, use the alternating current 220V wall power of closing on to power, its stability is low, can not ensure the communication reliability of IP dispatching telephone.
Summary of the invention
In order to overcome the problems referred to above, the invention provides one and utilizing Ethernet netting twine to realize IP dispatching telephone method of supplying power to.When existing Ethernet netting twine architecture does not do extensive change, while Ethernet netting twine is IP dispatching telephone transmission of data signals, direct current supply can also be provided for it.By the direct current supply of Ethernet netting twine, optimize installation and the power management of IP dispatching telephone, improve phone application reliability, greatly reduce equipment O&M cost.
The technical solution adopted in the present invention is:
Utilize Ethernet netting twine to realize IP dispatching telephone method of supplying power to, utilize terminal box, 4,5,7,8 cores idle by DC power supply access network based on ethernet line, realize by ethernet line directly for IP dispatching telephone is powered.
The positive pole negative pole of direct current supply line is connected with 7,8 cores with 4,5 cores of ethernet line by described terminal box respectively, and ethernet line 1,2,3,6 core is not cut off, and passes in terminal box.
Described ethernet line is CAT5 cable.
Described DC power supply is the-48V DC power supply that communication DC screen exports.
Utilizing terminal box, by DC power supply access network based on ethernet line, is that IP phone is powered by 4,5,7,8 pin of ethernet line.Only carry out transmission network signal with two pairs of lines of 1,2,3,6 pin in four pairs of lines of ethernet line, therefore can realize remote power feeding with unnecessary two pairs of netting twines, thus save power-supply wiring.Experiment proves, lower than the power supply of 60V and the signal of telecommunication parallel in netting twine time, power supply does not almost affect the signal of telecommunication.The operate power of IP dispatching telephone is generally between 10-30W, and operating voltage is direct current 48V, and the signal of telecommunication avoided in Ethernet netting twine affects the stable situation of Internet Transmission by DC power supply electromagnetic interference.Therefore can, according to IEEE 802.3at standard, be that IP dispatching telephone is powered by 4,5,7,8 pin of Ethernet netting twine.
Use the CAT5 cable of a standard, IP dispatching telephone is freed from the about intrafascicular of power line, the normal operation of network can be ensured while guaranteeing existing structureization wiring safety, reduce costs to the utmost.
Compared with prior art, the invention has the beneficial effects as follows:
1. reduce cost: without the need to carrying out loaded down with trivial details power-supply wiring again, the equipment that can not only save is powered and is built and maintenance cost, as power line, socket, pipeline and labour cost etc., also saves the time of arranging and installing needed for electric power system simultaneously;
2. safe and reliable: compared to alternating current 220V wall power, powered by communication DC switchboard, what can substantially increase IP dispatching telephone supplies electrical stability, ensures communication quality.
3. be widely used: be applicable to most transformer station.
4. be easy to promote: except being applied to IP dispatching telephone, the terminals such as communication machine room door, environmental monitoring data acquisition module, Ethernet switch all can apply this technology, and application prospect is extensive; Meanwhile, gate inhibition and environmental monitoring data acquisition module apply this technology, and terminal equipment can be arranged on ceiling neatly, cut off the optional positions such as top, reduces the constraint that power line is installed equipment.

In figure: 1, terminal box, 2, direct current supply line, 3, direct current supply line positive pole, 4, direct current supply line negative pole, 5, ethernet line, 6, ethernet line 4,5 core, 7, ethernet line 7,8 core.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.Fig. 1 is the 568B line sequence of Ethernet netting twine standard., 1-8 line sequence is respectively white tangerine, tangerine, Bai Lv, blue, and Bai Lan is green, Bai Zong, palm fibre.Fig. 2 is common machine room top plan view, can intuitive analysis be gone out by this figure, utilizes the Li Chu that ethernet line is powered.The ethernet line communicated by Fig. 2 in screen is through terminal box, and terminal box is placed on communication screen bottom surface; As shown in Figure 3, the ethernet line 5 in terminal box 1 is pushed aside protection overcoat about 5cm; Near transmission side place, four lines of blue race and brown race are cut off; Blue race two core long more than IP dispatching telephone side is connected on terminal box positive terminal, palm fibre race two core is connected on terminal box negative terminal, direct current supply line 2 is got suitable length and peels off oversheath, the positive and negative terminals of both positive and negative polarity difference thereto, the Lan Zuzong race of such ethernet line and ethernet line 4,5 core 6 and ethernet line 7, the 8 core 7 power line both positive and negative polarity of just drawing with DC distributor is respectively firm to be connected, wherein, blue two, race connects positive source 3, and two, brown race connects power cathode 4(IP dispatching telephone both positive and negative polarity and can not distinguish); Terminal box 1 is fixed; 568B line sequence pressure RJ45 connector is normally pressed in ethernet line both sides; Remain netting twine in transformer station's cable trough, by pipeline laying to IP dispatching telephone position.
At present, Dandong electric company has 9,220kV transformer station, 102,66kV transformer station, 1, agent maintenance 500kV transformer station of Xintong Co.Each transformer station all can implement according to this programme, and can use manpower and material resources sparingly millions of unit.
