Description
Technical field
The utility model belongs to energy-conserving road lamp control technology field, specifically a kind of outdoor independent streetlight control box.
Background technology
Existing outdoor solar energy, wind powered street lamp charge to the storage battery in the street lamp through solar energy and wind energy, give street lamp power supply, road lamp power supply through the discharge of storage battery then.The design of present outdoor solar energy, wind powered street lamp charging and discharge is too simple, does not have overvoltage protection and under-voltage protection function, makes storage battery can not be operated under the normal operating voltage, has influenced the life-span and the service behaviour of storage battery.
Summary of the invention
The purpose of the utility model is to above-mentioned deficiency a kind of outdoor independent streetlight control box that can improve the life of storage battery and service behaviour to be provided.
The utility model is achieved in that and comprises the single-chip microcomputer with inverter signal interface and city's electric signal interface; It is characterized in that: it also comprises overvoltage protection detection module, under-voltage protection detection module and PWM (Pulse Width Modulation; Pulse width modulation) off-load module; Wherein, First signal output part of said overvoltage protection detection module connects PWM off-load module, and the secondary signal output of overvoltage protection detection module connects the signal input part of under-voltage protection detection module, and first signal output part of under-voltage protection detection module connects an inverter signal interface of single-chip microcomputer.
Be connected with the overload protection detection module between another inverter signal interface of the secondary signal output of said under-voltage protection detection module and single-chip microcomputer.
The overvoltage protection detection module of the utility model setting, under-voltage protection detection module, overload protection detection module, PWM off-load module match with single-chip microcomputer; Can control battery-operated under normal operating voltage, the service behaviour of the life-span of prolongation storage battery, raising storage battery.
Description of drawings
Fig. 1 is the user mode theory diagram of the utility model.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Embodiment: comprise single-chip microcomputer, overvoltage protection detection module, under-voltage protection detection module and PWM off-load module with inverter signal interface and city's electric signal interface; Wherein, First signal output part of overvoltage protection detection module connects PWM off-load module; The secondary signal output of overvoltage protection detection module connects the signal input part of under-voltage protection detection module; First signal output part of under-voltage protection detection module connects an inverter signal interface of single-chip microcomputer, is connected with the overload protection detection module between another inverter signal interface of the secondary signal output of under-voltage protection detection module and single-chip microcomputer, promptly becomes the utility model.
When the utility model used, the signal input part of overvoltage protection detection module connected storage battery, and city's electric signal interface of single-chip microcomputer connects civil power, and the signal output of single-chip microcomputer connects street lamp.
The AC energy of wind-driven generator output converts direct current energy earlier to, then with solar cell together to charge in batteries.When overvoltage protection detection module detects electric energy that solar panel and wind-driven generator the send needs (promptly greater than 28V) above storage battery and inversion energy, PWM off-load module is carried out stepless unloading with unnecessary energy.Under normal unloading situation, can guarantee the battery tension all-the-time stable at the floating charge pressure point, just unnecessary electric energy is discharged in the off-load.Thereby guaranteed best charge in batteries characteristic, made electric energy be fully used, and guaranteed the useful life of storage battery.
Signal after above-mentioned process overvoltage protection detects carries out under-voltage protection and detects again through the under-voltage protection detection module, when battery tension is lower than " under-voltage point (being 23V) ", damages storage battery for fear of overdischarge, and control single chip computer cuts off inversion output.When treating that voltage rises to " under-voltage recovery point ", control single chip computer recovers inversion output.
Signal after the under-voltage protection of above-mentioned process detects carries out overload protection and detects again through the overload protection detection module, when detected interchange power output surpasses rated power, and control single chip computer cut-out inversion output.
Under or the state that inversion is broken down under-voltage when storage battery, single-chip microcomputer can be with load automatic switch to mains-supplied, thereby has ensured the power supply stability of system.After the inversion operate as normal, can automatically switch to the inversion power supply again.
