Moreover, with the construction and development of cities, the demand for street lights is still increasing, and the power loss is also increasing year by year, requiring more power supply.
目前，对于路灯电能损耗问题，较广泛的解决方式是改造路灯结构，利用太阳能对路灯供电，但现有供电技术中，通常只能利用强光来供电，有效地解决了晴天时路灯的供电情况，但在阴天、太阳光较微弱的情况下，不能很好地利用光能，使得阴天只能依赖市电供电，在阴天较多时依然会产生较大电能损耗，当城市停电时，路灯的照明便无法很地的保证，不利于城市管理。At present, for the power loss problem of street lamps, a wider solution is to transform the structure of street lamps and use solar energy to supply power to street lamps. However, in the existing power supply technology, usually only strong light can be used for power supply, which effectively solves the power supply situation of street lamps in sunny days. , but in the case of cloudy days and weak sunlight, light energy cannot be used well, so that cloudy days can only rely on mains power supply, and there will still be a large power loss when there are many cloudy days. When the city has a power outage, The lighting of street lamps cannot be guaranteed very well, which is not conducive to urban management.

The voltage detection device is respectively connected with the solar controller 105, the control device 103, and the photovoltaic cell 104; the voltage detection device is used to detect the voltage of the photovoltaic cell 104, and send the voltage to the The control device 103 and the solar controller 105 are described above.
所述节能路灯头的具体工作原理如下：The specific working principle of the energy-saving street lamp head is as follows:
通过所述光伏电池104在晴天的强光下电压较大，阴雨天的微弱光下电压较小，当天气云层太厚层，其电压更小，根据该规律采用电压检测装置实时检测光伏电池104的电压，并将测得的电压值传输至控制装置103和太阳能控制器105，以激发其开启相应功能。The voltage of the photovoltaic cell 104 is relatively large under strong light on a sunny day, and the voltage is relatively small under weak light on a rainy day. When the cloud layer is too thick, the voltage is even smaller. According to this rule, a voltage detection device is used to detect the photovoltaic cell 104 in real time. and transmit the measured voltage value to the control device 103 and the solar controller 105, so as to stimulate them to start corresponding functions.
当所述电压检测装置检测到的电压值大于或等于第一设定值时，所述控制装置103控制所述太阳能控制器105进行工作，启动强光下的太阳能充电模式。When the voltage value detected by the voltage detection device is greater than or equal to the first set value, the control device 103 controls the solar controller 105 to work, and starts the solar charging mode under strong light.
作为具体实施例，当所述太阳能控制器105选用MPPT控制器时，所述MPPT控制器自动跟踪并利用最大功率跟踪点对所述储能装置102时行充电，以确保储能装置102从光伏电池104中获取最大的能量，保证强光下的储能，进而由充电后的储能装置102对所述光源101供电。As a specific embodiment, when the solar controller 105 selects an MPPT controller, the MPPT controller automatically tracks and uses the maximum power tracking point to charge the energy storage device 102 in real time, so as to ensure that the energy storage device 102 The maximum energy is obtained from the battery 104 to ensure energy storage under strong light, and then the light source 101 is powered by the charged energy storage device 102 .
当所述电压检测装置检测到的电压值小于所述第一设定值时，由于充电电压较小，无法直接对所述储能装置102进行充电，因此所述控制装置103控制所述太阳能控制器105停止工作，并控制所述组态开关106开始工作，启动间歇脉冲微弱光充电模式。When the voltage value detected by the voltage detection device is lower than the first set value, the energy storage device 102 cannot be directly charged due to the small charging voltage, so the control device 103 controls the solar energy control The device 105 stops working, and controls the configuration switch 106 to start working, and starts the intermittent pulse weak light charging mode.
具体地，通过组态开关106的通断所形成的脉冲高幅度电压来对所述储能装置102进行充电，保证微弱光下的储能，进而由充电后的储能装置102对所述光源101供电，保证微弱光下光源101的正常照明。Specifically, the energy storage device 102 is charged by the pulse high-amplitude voltage formed by the on-off of the configuration switch 106 to ensure the energy storage under weak light, and then the charged energy storage device 102 charges the light source. 101 is powered to ensure the normal illumination of the light source 101 under weak light.
其中，所述组态开关106是以一定的预设频率进行通断的，该预设频率由所述控制装置103根据所述电压值进行设定。Wherein, the configuration switch 106 is turned on and off at a certain preset frequency, and the preset frequency is set by the control device 103 according to the voltage value.
在晴天和一般阴雨天气下，通过上述太阳能充电模式和微弱光充电模式的结合，无论在晴天还是阴雨天都能持续对储能装置102进行充电，且微弱光充电效率比传统方式提高了20％以上，增加了储能装置102的充电量，以及对光源101的持续能量供给，使城市路灯头的光源101能够最大程度地利用自然光的能量，免于对市电电能的浪费，同时还具有高精度温度补偿功能。In sunny and generally rainy weather, through the combination of the above solar charging mode and weak light charging mode, the energy storage device 102 can be continuously charged no matter in sunny or rainy days, and the charging efficiency of weak light is 20% higher than that of traditional methods As mentioned above, the charging capacity of the energy storage device 102 and the continuous energy supply to the light source 101 are increased, so that the light source 101 of the urban street lamp head can utilize the energy of natural light to the greatest extent, avoiding the waste of mains power, and at the same time has high Precision temperature compensation function.
当云层过厚，所述电压检测装置检测到的电压值小于第二设定值(第二设定值小于第一设定值)时，所述储能装置102可能充电不足，此时由所述控制装置103控制所述电源转换器107引入市电，使市电和储能装置102共同对所述光源101供电，且市电和储能装置102均通过所述太阳能控制器105对所述光源101供电，其中，经过所述太阳能控制器105的调节，此时引入的市电仅用于对光源101进行供电，而不用于对储能装置102进行充电，最大程度地节约了市电电能。When the cloud layer is too thick and the voltage value detected by the voltage detection device is less than the second set value (the second set value is less than the first set value), the energy storage device 102 may be insufficiently charged. The control device 103 controls the power converter 107 to introduce commercial power, so that the commercial power and the energy storage device 102 jointly supply power to the light source 101, and the commercial power and the energy storage device 102 are both connected to the solar controller 105 by the solar controller 105. The light source 101 supplies power, wherein, after the adjustment of the solar controller 105, the mains power introduced at this time is only used to power the light source 101, not to charge the energy storage device 102, which saves the power of the mains to the greatest extent. .
在极端天气云层过厚的情况下，即使用微弱光充电也难以满足充电要求时，采用上述市电与储能装置102共同供电，能够结合两种供电方式的优势，保证光源101的持续使用；同时市电仅供电不充电的模式，能够减少对市电电能的浪费。In the case of extreme weather where the cloud cover is too thick and it is difficult to meet the charging requirements even with weak light charging, the above-mentioned mains power and the energy storage device 102 are used for power supply, which can combine the advantages of the two power supply methods to ensure the continuous use of the light source 101; At the same time, the mode of only supplying electricity without charging can reduce the waste of electric energy of the mains.
通过本发明实施例所述的一种混合供电的节能路灯头，可以实现的技术效果为：采用用储能装置102和市电进行双模式供电，并针对太阳能的强光、弱光以及储能装置102的充放电特性，采用太阳能充电和微弱光(微光能)充电进行双模式充电，能够增加阴雨天气的充电量，保证阴雨天气时路灯的正常照明，且即使城市停电也能保证点亮城市路灯。Through the energy-saving street lamp head with mixed power supply described in the embodiment of the present invention, the technical effect that can be realized is: adopt dual-mode power supply with energy storage device 102 and mains power, and aim at the strong light, weak light and energy storage of solar energy The charging and discharging characteristics of the device 102, using solar charging and weak light (twilight energy) charging for dual-mode charging, can increase the charging capacity in rainy weather, ensure normal lighting of street lights in rainy weather, and ensure lighting even if the city's power is cut off City street lights.
