The electric ballast terminal monitor of street lamp
Affiliated technical field
The present invention is applied to the city illumination street lamp, at the electric ballast street lamp, carries out the monitor terminal list lamp network monitoring device of wireless monitor, control, antitheft and administration of energy conservation.
Under the propelling that urban modernization is built, street lighting equipment is promoted city image and important function has been played in the urban modernization development.Electric ballast is compared with traditional electric ballast, and the power of autophage is little, and the starter conditional request is low, and is little to the influence of lamp tube service life, so electric ballast is constantly enlarging occupation rate, and capturing the market of electric ballast step by step.Existing control method to the electric ballast street lamp is exactly to set the ON/OFF lamp time in the control cabinet at the scene to disperse time control, by the scene action of control light is set.This method can not in time be adjusted the time of ON/OFF lamp, more can't in time reflect the ruuning situation of lighting installation, cause problems such as failure rate height, maintenance difficult, simultaneously, equipment such as cable and ballast also faces more and more serious pilferage to be threatened, and presses for timely burglar alarm.While is along with the continuous expansion of city size, the scope of street lamp application also enlarges thereupon, make maintenance overhaul work very complicated more, past, artificial monitoring, inspection was difficult to solve a problem promptly, equipment theft simultaneously can only be waited for civic phone reflection usually passively, is difficult to accomplish timely maintenance.
Summary of the invention
For monitoring, control and the management mode of strengthening city electric ballast street lamp, increase burglary insurance measure to it.Through further investigation for a long time, to sum up situation is invented out the terminal monitoring equipment at the electric ballast street lamp.Use this equipment to carry out data sampling, analysis and storage, and send electrical quantity report, Trouble Report and alarm report, and carry out the order that the streetlight monitoring network is assigned to the streetlight monitoring network to street lamp.
The present invention is solved over the technical scheme that electric ballast street lamp existing problems are taked and is: a terminal monitor equipment is installed on every street lamp.One end is connected with power supply, and an end is connected with electric ballast.When electric current by the time provide collection electric power through power module for equipment, electric current connects the acquisition chip group through the voltage transformer summation current transformer simultaneously.The acquisition chip group is made up of AD, CPU and Acquisition Circuit, and automatic collection analysis and store voltage, electric current and power and power factor through instrument transformer conveys to the Communication Control group with the result that draws with the form of digital signal.The Communication Control group is made up of filter circuit, crystal oscillator, CPU, clock chip and communicating circuit, receives data after CPU handles, and data are gathered, analyzed and store.The Communication Control group is connected with antenna (gain 2.5dB-4.5dB frequency, employing 2.4G-2.5G common channel) with relay, by antenna the data (alarm or Trouble Report) of gathering is sent to electric ballast street lamp Control Network.The Communication Control group is analyzed, is stored by the data of being sent by the street lamp Control Network that antenna is received, and carries out the control command of being assigned by the street lamp Control Network by control relay then, control electric ballast road lamp switch.The Communication Control group is connected with digital regulation resistance simultaneously, thereby the resistance of control figure potentiometer realizes the adjusting of power output, and the power of control electric ballast reaches the purpose of controlling street lamp brightness.
The invention has the beneficial effects as follows, running by the electric ballast terminal monitor of street lamp, accurately carry out the ballast switch, regulate street lamp brightness, the street lamp running status is carried out data sampling, carry out sampling analysis again, Trouble Report and burglar alarm report are sent to electric ballast street lamp Control Network by antenna.Thereby the demands such as monitoring, control, security and maintenance of single lamp have been satisfied.Solved the problem of street lamp Control Network, improved monitoring promptness, accuracy and control convenience the monitoring, control and security of electric ballast street lamp.

In Fig. 1, terminal monitor 3 one ends are connected with 220V input supply terminal 4, and the other end is that power output end 8 is connected with electric ballast 1, and the power control output end links to each other with electric ballast 1 simultaneously.
Electric current enters terminal monitor 3 and provides the collection power supply by power supply 15 for terminal monitor 3.Electric current enters terminal monitor 3 and directly connects acquisition chip group 14 via voltage transformer 5 summation current transformers 6.Acquisition chip group 14 is made up of AD, CPU and Acquisition Circuit, and the data that 6 transmission come to voltage transformer 5 summation current transformers are carried out collection, analysis and the storage of voltage, electric current, power and the power factor of single lamp.Pass to the Communication Control group 10 that connects acquisition chip group 14 with digital signal again, Communication Control group 10 is made of clock chip, communicating circuit, filter circuit, crystal oscillator and CPU.Communication Control group 10 is collected the data of acquisition chip group 14 after draw data after the CPU Treatment Analysis, sends image data by antenna 7, and Trouble Report and burglar alarm signal are uploaded to electric ballast street lamp Control Network.The data that transmitted by Communication Control group 10 are analyzed, stored to relay 9 simultaneously, and carry out the switch motion of electric ballast 1.The resistance of Communication Control group 10 control figure potentiometers 11, the size of control power output, the brightness of control street lamp.Relay 9, Communication Control group 10, digital regulation resistance 11, acquisition chip group 14, power supply 15 all need ground connection, earthy 13 expressions among the figure.
