Description

A kind of automatic transposition street lamp control system

Technical field

The utility model relates to the intelligent street lamp control system technical field.

Background technology

Street lamp is the important component part of urban construction, the regular or irregular maintenance street lamp of municipal sector's meeting; But because the making material difference of bulb, the operational environment difference, its, length differed in useful life, and is untimely because safeguarding unavoidably, causes certain difficulty to passerby's trip; In order to keep in repair street lamp, need to drop into a large amount of man power and materials, and most maintenance all is to change the bulb that breaks down simultaneously.

Prior art is around the research of street lamp, and a direction is exploitation low energy consumption street lamp, for example LED lamp; Other directions are research street lamp centralized control systems, also have some directions are how conveniently to change street lamp; These research directions have all reduced the street lamp maintenance cost to a certain extent, but how under the prerequisite that road lamp solidifies, reduce road lamp with the frequency of changing, prolong with changing the cycle, and be the important topic that we face.

Summary of the invention

The invention technical problem to be solved provides a kind of replacement cycle that can prolong bulb, reduces the automatic transposition street lamp control system of frequency of maintenance.

The invention is for solving the problems of the technologies described above, by the following technical solutions:

This novel street lamp is the many groups of device bulb in lampshade, cooperates automatic control system, when automatic control system detects one group of bulb cisco unity malfunction, then another is organized normal bulb and is indexed into working position, thereby avoid bulb once damaging the drawback that need change.Concrete, realize by following scheme:

The automatic transposition street lamp control system of the invention comprises the electronic control module whether mechanical Executive Module of implementing the street lamp transposition and detection, control street lamp replace and how to replace;

Described mechanical Executive Module comprises the lamp socket that connects several bulbs, with transmission of power to the transmission mechanism of lamp socket and power source that power is provided;

Whether described electronic control module comprises for detection of working position the bulb photo-sensitive cell, the controller that is used for reading the photo-sensitive cell signal and determines whether to send action command according to unlike signal of operate as normal, described power source is indexed into working position according to controller instruction action by spare bit bulb on the transmission mechanism drive lamp socket.

Further, described power source is set to stepping motor.

Further, to read signal be current signal to described controller.

Further, the zero line of described several bulbs links to each other, and is connected with zero-power line.

Further, the live wire contact electrode is installed on the base of described each bulb, when bulb was positioned at work site, this live wire contact electrode contacted automatically with the power firestreak fixed electrode circuit is connected.

Owing to adopted technique scheme, the invention to have following beneficial effect:

1, rotatable lamp socket of design in lampshade is passed through in the invention, and arranges a plurality of bulbs, replaces the street lamp of single bulb commonly used at present.By the spare bulb fault bulb operate as normal of in time substituting, it is short to solve single bulb life cycle, change frequent, problems such as maintenance cost height.

2, the automatic control system loop control that is made of power source-photo-sensitive cell of photo-sensitive cell-controller-reception controller instruction has reached and need not manual operation, and transmission combines with sensing function, the automatic control of realization system.

3, at the base of each bulb the live wire contact electrode is installed, the live wire contact electrode of the bulb by being positioned at the position, working point contacts automatically with the power firestreak fixed electrode and makes the circuit connection, has realized the circuit connection problem of bulb on the lamp socket.

4, the zero line with bulb links to each other, and is connected with zero-power line, draws zero line by the bearing inner race that is arranged in the lampshade, has well solved the problem that power line twines.

Embodiment

In conjunction with Fig. 1 and Fig. 2, the automatic transposition street lamp control system of present embodiment comprises the electronic control module whether mechanical Executive Module of implementing the street lamp transposition and detection, control street lamp replace and how to replace.Wherein, mechanical Executive Module is along the power transmission direction, is made of stepping motor 5, gear train assembly, lamp socket 2 and several bulbs 1 of being arranged on the lamp socket successively; For better controlling lamp socket 2 transposition precision, driving wheel 4 and the driven pulley 3 of gear train assembly are set to mitre gears; Bulb 1 arranges in lamp socket 2 circumference equal intervals.The zero line of bulb 1 links to each other, and is connected with zero-power line.Live wire contact electrode 7 is installed on the base of each bulb.Electronic control module comprises the whether photo resistance photo-sensitive cell of operate as normal of testing position bulb, reads the AT89S-51 single-chip microcomputer of photo resistance current signal.

When the transposition street lamp control system is worked automatically, being placed in the lampshade, specifically is that the driven pulley 3 of mechanical Executive Module is connected with Shade base by bearing 6, and bearing outer ring is fixed, and bearing inner race connects the bulb zero line 8 of drawing.The photo resistance of electronic control module places working position bulb below, and the IO port of single-chip microcomputer connects photo resistance and stepper motor driver by holding wire.

In conjunction with Fig. 3, work as bulb malfunction, the light that photo resistance is experienced by the signal that dies down by force after, resistance increases, electric current reduces in the circuit; Single-chip microcomputer receives this variable signal and deals with, and then stepper motor driver is sent the instruction of rotation.When stepper motor driver receives the single-chip microcomputer pulse signal, drive stepping motor and rotate a fixing angle by the direction of setting, control commutation order.Namely can the pilot angle displacement by the control impuls number, thus reach the purpose of accurate location.Angular displacement and rotation direction that stepping motor rotates can be by the program settings of single-chip microcomputer input.By gear driven lamp socket and bulb rotation, live wire contact electrode 7 contacted with being arranged on the interior power firestreak contact electrode of lampshade when standby bulb rotated to work site when stepping motor rotated, and bulb is just normally luminous, and stepping motor stops the rotation.
