Abstract
The utility model discloses an intelligent energy-saving electric control device for a street lamp, which comprises a driving circuit, an executive circuit and a high-voltage sodium lamp which are connected in sequence, wherein a controller and a feedback device are connected between the driving circuit and the high-voltage sodium lamp, and the controller and the feedback device comprise a shared digital processor DSP (digital signal processor). The intelligent energy-saving electric control device for street lamp has the advantages that the energy is saved, the output voltage can be self-adjusted, and the service life of the gas discharge lamp is prolonged.
Description
Technical field
The utility model relates to street lamp, specifically is meant a kind of device that street lamp is carried out the electric control of intelligent economize on electricityization.
Background technology
Present domestic road lighting switch lamp generally adopts timing controlled, and the switch lamp time needs frequent manual adjustment with seasonal variations.For energy-conservation, often adopt evening lamp, on-off mode is to light at interval or the street lamp of positioned opposite is extinguished on one side.In fact this control mode is a science not, and breakneck, because can greatly reduce the uniformity of road brightness like this, greatly is increased in and is extinguished the possibility that traffic accident takes place in the dark area that street lamp contains.
For traditional control mode, because these power save modes exist comparatively significantly shortcoming, the control of the ON/OFF lamp of domestic most of city street lamps is by each transformer (distribution box) decentralized control, although the city street lamp operation has special control line, has only controlled function and can't realize monitoring.Owing to can not control in strict accordance with outdoor natural light illumination, not only real-time is poor, the failure rate height, and also waste is serious.In addition, traditional control method will be asked for help and do not left the post, and in time controls the opening and closing of light, is very much surprising owing to the Artificial Control error causes waste of energy.During such as employing timer control mode, because the time difference throughout the year will often manually be adjusted timer, from the Summer Solstice to Winter Solstice, sunrise time retardation, sunset time are in advance; From Winter Solstice to the Summer Solstice, at sunrise between in advance, sunset time postpones, weather phenomenon requires the road lamp switch time to adjust according to sun set/raise time in view of the above].So not only consume a large amount of human resources, also may be owing to adjusting the untimely waste that causes.
The utility model content
The problem that the utility model need solve provide a kind of energy-conservation, can the self-control output voltage, prolong the gaseous discharge lamp street lamp intelligent energy-saving control device in useful life.
For realize above-mentioned from, the utility model is designed a kind of street lamp intelligent energy-saving control device, comprises the order drive circuit, executive circuit and the high pressure sodium lamp that are connected, is connected with controller and feedback device between drive circuit and the high pressure sodium lamp.
Described controller and feedback device comprise shared digital processing unit DSP.
Described digital processing unit DSP is connected with voltage-phase input circuit, voltage, current amplitude testing circuit, jtag interface, RS232 serial ports, and digital processing unit DSP outputs a control signal to drive circuit.
The utility model street lamp intelligent energy-saving control device has the following advantages:
(1). lamplit luminous flux is not less than minimum limit value, keeps street lamp voltage steady, reaches the needs of energy-conservation and satisfied illumination, so still be that low ebb is stabilized in supply power voltage in the prescribed limit all the time on the peak of electricity consumption no matter;
(2). can guarantee the high lamplit energy conversion efficiency of trying one's best, make it to have higher service efficiency;
(3). do not influence the useful life of gaseous discharge lamp.

Fig. 2 is the controller of the utility model street lamp intelligent energy-saving control device and the functional-block diagram of feedback device.
Embodiment
For the ease of those skilled in the art's understanding, structural principle of the present utility model is described in further detail below in conjunction with specific embodiment and accompanying drawing:
As shown in Figure 1, a kind of street lamp intelligent energy-saving control device, street lamp intelligent energy-saving control device comprises drive circuit, executive circuit and high pressure sodium lamp that order is connected, is connected with controller and feedback device between drive circuit and the high pressure sodium lamp.Whole as seen from Figure 1 road lamp energy-saving control device is closed-loop control, the setting voltage at high-pressure sodium lamp two ends and feedback signal enter the A/D change-over circuit in the intelligent controller simultaneously, controller with the two through comparison, computing, control the control signal of device entirely by changing executive circuit, thereby change the supply power voltage at high-pressure sodium lamp two ends, the brightness of control high-pressure sodium lamp, thus be able to the switching time that device is controlled in continuous control entirely, realize self-regulating purpose.Drive circuit in the utility model, executive circuit, controller and feedback device can adopt existing ripe circuit or building block technique.
As shown in Figure 2, described controller and feedback device comprise shared digital processing unit DSP.Digital processing unit DSP is connected with power supply, sheet outer RAM, LED, keyboard, voltage-phase input circuit, voltage, current amplitude testing circuit, jtag interface, RS232 serial ports, digital processing unit DSP outputs a control signal to drive circuit, is connected with GPRS by the RS232 serial ports.The model of digital processing unit DSP can be TMS320LF2407A, and it is used for finishing the functions such as detection processing of voltage intelligent control algorithm, PWM generation, associated voltage, electric current.TMS320LF2407A DSP is the Electric Machine Control dedicated digital signal processor of TI company exploitation, it can provide advanced signal processing and control reliably for the high-performance transmission with the operational capability of Digital Signal Processing and the one of being eager towards the high-effect control ability of motor.Control circuit also comprises the signal conditioning circuit and the input/output interface circuit of voltage detecting and current detecting simultaneously, to finish various functions
Foregoing is preferred embodiment of the present utility model only, is not to be used to limit embodiment of the present utility model, and those skilled in the art are according to design of the present utility model, and appropriate adaptation of having done or modification all should be within protection ranges of the present utility model.
