Abstract
The utility model relates to a long range power supplying system for monitoring a highway. The utility model solves the technical problem that the utility model provides the long range power supplying system for monitoring a highway for supplying electricity from a long range for a whole range monitoring system of a highway. The utility model solves the difficulty that because a route of the highway is far, electricity can not be used on site. The utility model provides a power supply system which has the advantages of high reliability, and simple and convenient accomplishment for the whole range monitoring system of the highway. The utility model has the technical scheme to solve the problem that the long range power supplying system for monitoring a highway is characterized in that the utility model is composed of a long range power supplying sending part, a long range power supplying receiving part and an electric cable transmission line, wherein the long range power supplying sending part comprises an AC/DC inverter, and a direct current power supply produced by the long range power supplying sending part is transmitted to the long range power supplying receiving part through the electric cable transmission line; the long range power supplying receiving part comprises a DC/AC or DC/DC inverter connected with a corresponding monitoring device. The utility model can be used in a whole range monitoring device of a highway.
Description
Technical field
The utility model relates to power supply, especially a kind of freeway surveillance and control remote electric power system.Be applicable to express highway all-way watch-dog such as video camera, atmospherium, Vehicle analyzer etc.
Background technology
Highway is compared with ordinary highway, has characteristics such as line style is good, the big road speed of the magnitude of traffic flow is fast, as not adopting advanced monitoring management measure, under the situation of, awful weather big at the volume of traffic, traffic accident and traffic jam takes place very easily.
The monitoring scheme of highway mainly is made of realtime graphic situation, vehicle flowrate and flow rate detection, emergency call and subsystems such as environmental monitoring, variable information board at present, as shown in Figure 1, mark 11 is that outfield rig camera, mark 12 is large-scale changeable-message sign for visibility detector, mark 14 for small-sized changeable-message sign, mark 15 for wagon detector, mark 13 among the figure, these checkout equipments in order to information that high-grade highway is provided as the situation of the vehicle flowrate on the whole piece circuit, weather conditions, black spot.As can be seen from Figure 1, the characteristics of the system-wide of high-grade highway monitoring are that the control point is many, long transmission distance, power taking difficulty on the spot.
In complete monitoring, because transmission line great distance, video monitoring, the power supply of instruments such as weather environment detector and vehicle flowrate survey meter becomes a great problem, what generally adopt at present is the form of powering to remote equipment by the power cable of laying from the set electric substation's AC power of highway, as shown in Figure 2, in this scheme, power devices adopts the remote power feeding form that exchanges, the AC energy that is positioned at communication power supply chamber or electric substation uses for complete monitoring equipment by the power cable long-distance transmissions, because distance, line drop is big, therefore also need increase necessary stabilized voltage power supply on the line.And because what adopt is that AC power is by the mode of cable to the apparatus remote power supply, if use the original pipeline parallel with telecommunication cable, because long transmission distance, certainly will bring interference to communication, therefore, highway both sides ditching laying form is separately changed in the laying of power cable, causes the increase of construction cost.The solar cell for supplying power of employing form is also arranged in addition, but be subjected to weather effect bigger, can not guarantee the normal power supply under long-time rainy weather.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of freeway surveillance and control remote electric power system that aims at the remote power-feeding of express highway all-way supervisory control system is provided.Be intended to solve highway because of the distance difficulty of power taking on the spot far away, the electric power system that a kind of reliability height is provided, is easy to implement for the express highway all-way supervisory control system.
The technical scheme that the utility model adopted is: the freeway surveillance and control remote electric power system, it is characterized in that it sends part, remote power feeding receiving unit, cable transmission line by remote power feeding and forms, remote power feeding sends part and contains the AC/DC converter, the DC power supply of its generation is transferred to the remote power feeding receiving unit through cable transmission line, the remote power feeding receiving unit contains DC/AC or DC/DC converter, and described converter is connected with pairing watch-dog.
The output that described remote power feeding sends AC/DC converter in the part is mounted with the standby battery group.
Described AC/DC converter is " N+X " redundant combining form.
The beneficial effects of the utility model are: the present invention is owing to adopt the direct current transportation form, the cable of electric energy transmitting can be laid in the original communication pipe of highway, avoided excavating separately necessity that raceway groove is laid, solved highway because of the distance difficulty of power taking on the spot far away, the method of supplying power to that a kind of reliability height is provided, has been easy to implement for the complete monitoring system, make equipment operation more reliable, maintenance workload reduces.

Fig. 2 is the form of the utility model prior art to the remote equipment power supply.
Fig. 3 is a systematic schematic diagram of the present utility model.
Embodiment
As shown in Figure 3, present embodiment is made up of remote power feeding transmission part 1, remote power feeding receiving unit 2, cable transmission line 3.Remote power feeding sends part 1 and mainly finishes the AC/DC conversion, and it contains AC/DC converter 1-1, and AC power is transformed into required DC power supply, and remote power feeding sends part 1 can be arranged on nearby highway with electric substation or charge station communication power supply chamber.For system can normally be used when electric substation's appearance has a power failure, DC UPS system configuration form is adopted in suggestion, promptly the output at AC/DC converter 1-1 articulates standby battery group 4, when civil power just often, provide the remote equipment electric energy and to battery charging by civil power, when city's electrical anomaly, then continue power supply by batteries.The DC power supply that remote power feeding sends part 1 generation is transferred to remote power feeding receiving unit 2 through cable transmission line 3, remote power feeding receiving unit 2 contains DC/AC or DC/DC converter 2-1, converter 2-1 again with pairing complete monitoring equipment 2-2 such as: video camera, atmospherium, Vehicle analyzer etc. are connected.Need use the watch-dog of AC power like this for video camera, can adopt the DC/AC converter, direct current energy is converted to required AC energy; Galvanic equipment can be used for some, then the DC/DC converter can be adopted.
Be the reliability of raising system power supply, described AC/DC converter 1-1 can adopt " N+X " redundant combining form.
For reducing line loss, direct current energy is transferred to remote equipment to be used, need to adopt the cable transmission line 3 in the suitable line footpath that is fit to transmission range and bearing power, this example adopts two core power cables, this cable transmission line can not exert an influence to signal of communication, therefore owing to the direct current energy that is that is transmitted, in wiring the time can be arranged in the galvanic cable transmission line of this transmission the pipeline that is in the center, road that cable such as communication grade uses, and need not lay in the roadside ditching separately.
