Description
Technical field
The present invention relates to a kind of street lamp Communication Monitoring protective switch electric appliance more particularly to a kind of street lamp intelligent monitoring devices.
Background technique
With the development of smart city, large quantities of intelligent road-lamp control monitoring devices are come into being, and have data monitoring, event
Barrier reports, GPS positioning, automatic control, remotely the multi-functional single-lamp controller such as control, Energy Saving Control, electrocution-proof protection obtains
Effective development and utilization.While product function is more and more, similarly there is drawback in some functions.
Existing street lamp intelligent monitoring device suffers from the drawback that
In city street lamp field, streetlight monitoring device is built using communication modes such as GPRS, LoRa, MB with street lamp background system
Vertical connection, background system can recruit reading, issue related data and control command, and streetlight monitoring device can also active reporting failure letter
Breath, can grasp the currently running state of street lamp, this makes road lamp management obtain comprehensive intelligence, gives city street lamp pipe in time in this way
Reason offers convenience.But often because communication signal is bad in reality, the reasons such as distribution system has a power failure cause communicating interrupt, backstage
System cannot obtain information in time, and the two is unable to get effective differentiation.In street lamp operation, because of distribution system power failure or street lamp
Monitor power supply breaks down, this makes communication module power loss, can not realize that failure reports and data communication in time, in this way
Background monitoring system can not also judge that communication signal disappears or streetlight monitoring device non-transformer causes.
It is complained when traditional street lamp fault and is found by management personnel's inspection or pedestrian, not only caused in this way
The maintenance workload of administrative department, and pedestrian complains and causes undesirable social influence, and simultaneous faults street lamp cannot be timely
Maintenance replacement, traffic lighting cannot get effective guarantee, and there are traffic safety hidden danger.
Novel street lamp control system solves the above problem substantially, and solution is to detect street lamp using single-lamp controller
Come what is judged, it is zero that main judgement, which is electric current, for the variation of electric current, or setting is compared by the percentage of each lamp actual current,
Lamp failure is thought lower than how much values, back-stage management center is then uploaded to by wireless network, is known at the first time by administrative staff
Know failure lamp stand, this obviously solves the artificial investigation failure problems in part, has saved cost.However in street lamp actual motion, tool
There is the phenomenon that Diversified Products such as Novel LED light, energy-saving lamp and traditional high-pressure sodium lamp coexist, watt level is irregular, always
For the actual motion electric current of street lamp can change that (energy-saving lamp is generally in 100mA~500mA, LED light in 100mA~8000mA
600mA~2000mA, high-pressure sodium lamp 2000mA~8000mA), need to set corresponding fault current benchmark in fault detection
Value carries out the discrimination of street lamp fault, very time-consuming and laborious in this way.And LED light can all reach energy conservation by dimming mostly now
Purpose mainly controls the input voltage of street lamp, adjusts the brightness of street lamp, local some departments are to light modulation power conservation requirement degree
Also different, in this way the control of setting fault current a reference value is difficult to accomplish, and will cause street lamp fault information wrong report feelings
Condition loses more than gain instead in this way.Wisdom street lamp development today, how more reasonable effective solution street lamp fault it is accurate
It distinguishes, improves working efficiency, save the cost is that today's society must solve the problems, such as.
Current all single-lamp controllers the open and close of control street lamp mainly use timing controlled, longitude and latitude control,
Light sensation controls, manually controls, long-range modes such as control, and wherein longitude and latitude control street lamp divide-shut brake is the most convenient, controls throughout the year

The open and close of street lamp；This control mode largely improves the management level of street lamp, unlike timing controlled needs
The time is manually adjusted according to seasonal variations, to intelligent management band convenience, improved work efficiency to a certain extent.But with
And the problem come is to need to input accurate latitude and longitude value to controller for road lamp for each area just can accurately be controlled
System, but because areal variation is very big, the day of the especially eastern and western regions sun rises sunset time and differs greatly, and needs for eachly
Area's matching longitude and latitude, which can be only achieved, to be precisely controlled, and is mainly achieved in that at present solid individually for certain area's setting when producer's production
Determine latitude and longitude value or scene and data are arranged by infrared, RS485 according to local latitude and longitude value, spends a large amount of manpower object in this way
Power.Each department stock is be easy to cause in the supply of material not in time, the phenomenon that misdelivery, and scene setting longitude and latitude numerical value is all easy
Error leads to the control street lamp branch wire time dislocation of local longitude and latitude, causes street lamp to malfunction in this way, should not bright light when bright light,
The or not when bright light.
With the development of wisdom street lamp, the single-lamp controller with communication function is used and is given birth to, to grasp each street lamp
Correlation circumstance, each single-lamp controller have a fixed address, and the upload of Lai Shixian data and receiving backstage are
The instruction that system is sent, this just needs product before factory, there is unified address number, the corresponding item of each product
Otherwise code will muddle things up in complicated street lamp communication system, and can not track the practical operation situation of specific lamp stand；Simultaneously in street lamp
Before system operation, the streetlight monitoring device address that power distribution station is administered need to be entered into system, be unable to repeat to address (RA) typing,
It can not leak and set address, mistake sets address, and otherwise part street lamp will be unable to establish communication channel.In all operation links, need
It largely manually goes to realize and implement, and be easy to cause address that mistake is set in the whole process, bar code is lost, and real feelings are waited
Condition, will lead to road lamp system reporting fault information errors in this way and information loss is not complete, have identical address failure not report.
