Description
Technical field
This utility model relates to a kind of traffic flow detecting device.
Background technology
Along with China's expanding economy and the continuous expansion of city size, automobile quantity increases day by day, traffic administration and road
The pressure that road is built is increasing.Wherein, vehicle flowrate is detected as traffic administration and road construction provides propping up in data
Hold.Currently, the mode generally used is to detect wagon flow by being embedded in the traffic flow detecting device under track and add up.But, if traffic flow detecting device is embedded in underground, it is necessary to provide supply line and data transmission link, add the workload of track laying and maintenance simultaneously.
POE(Power Over Ethernet) refer in the case of existing Ethernet Cat.5 wiring architecture does not makes any changes, while for some IP-based terminals (such as IP telephone machine, wireless local network connecting point AP, web camera etc.) transmission data signal, moreover it is possible to the technology of direct current supply is provided for this kind equipment.POE technology can ensure the normal operation of existing network while guaranteeing existing structureization wiring safety, reduces cost to greatest extent.
Utility model content
The problem that this utility model solves is to provide the traffic flow detecting device that a kind of POE of employing powers.
For solving the problems referred to above, the traffic flow detecting device that this utility model provides, it is characterized in that: include casing and the control module being located in casing, vehicle Flow Detection module, Ethernet transport module and POE power management module, the rear end face of casing is provided with RJ45 interface, the incoming end of RJ45 interface is connected to the Ethernet with POE function of supplying power, the end that picks out of RJ45 interface is respectively connecting to input and the Ethernet transport module of POE power management module, and control module connects vehicle Flow Detection module and Ethernet transport module respectively.
Based on above-mentioned, described POE power management module includes current rectifying and wave filtering circuit and decompression voltage regulator, current rectifying and wave filtering circuit is delivered to the input of decompression voltage regulator after the voltage signal that RJ45 interface inputs is carried out rectifying and wave-filtering, the outfan of decompression voltage regulator is that control module, vehicle Flow Detection module and Ethernet transport module are powered.
Based on above-mentioned, described vehicle Flow Detection module is geomagnetic sensor.
Pass through such scheme, this utility model uses POE power supply technique, the incoming end of RJ45 interface is connected to the Ethernet with POE function of supplying power, only need a netting twine can realize power supply and networking simultaneously, this utility model is made to eliminate the trouble laying power line, make easy for installation, and reduce cost.
Accompanying drawing explanation
Fig. 1 is the circuit structure block diagram of this utility model traffic flow detecting device.
Detailed description of the invention
As shown in Figure 1, traffic flow detecting device, it is characterized in that: include casing and the control module being located in casing, vehicle Flow Detection module, Ethernet transport module and POE power management module, the rear end face of casing is provided with RJ45 interface, the incoming end of RJ45 interface is connected to the Ethernet with POE function of supplying power, the end that picks out of RJ45 interface is respectively connecting to input and the Ethernet transport module of POE power management module, and control module connects vehicle Flow Detection module and Ethernet transport module respectively.
Based on above-mentioned, described POE power management module includes current rectifying and wave filtering circuit and decompression voltage regulator, current rectifying and wave filtering circuit is delivered to the input of decompression voltage regulator after the voltage signal that RJ45 interface inputs is carried out rectifying and wave-filtering, the outfan of decompression voltage regulator is that control module, vehicle Flow Detection module and Ethernet transport module are powered.
Based on above-mentioned, described vehicle Flow Detection module uses geomagnetic sensor HMC5883, and described control module uses single-chip microcomputer MSP430, and described Ethernet transport module uses ethernet transceiver DM9161.
During use, only RJ45 interface need to be linked into the Ethernet with POE function of supplying power.The voltage signal that RJ45 interface inputs first is carried out rectifying and wave-filtering by POE power management module, powers then to after carrying out lowering and stabilizing blood pressure control module, vehicle Flow Detection module and Ethernet transport module.The signals of vehicles detected is sent to control module by vehicle Flow Detection module, and control module carries out statistical analysis to signals of vehicles, and the signals of vehicles quantity according to detecting in the unit interval is calculated vehicle flowrate data.Vehicle flowrate data are passed to Ethernet transport module by control module, Ethernet transport module vehicle flowrate data are sent to the Ethernet that RJ45 interface is accessed.
