Be applied to the intelligent energy supply system of elevator

Technical field

The present invention relates to a kind of elevator energy supplying system that utilizes regenerative resource, relate in particular to a kind of intelligent energy supply system that can automatically configure energy-storage module charge and discharge process, all kinds of energy unit of flexible utilization and simplify elevator energy supply hardware configuration cost.

Background technology

Development along with human society, the construction in city is being updated, and high buildings and large mansions are signifying growth momentum and the flourishing sign in city, and wherein elevator is the important composition unit of high buildings and large mansions, also be the walking-replacing tool that the mankind rely on, it is convenient that the life that elevator is the mankind has brought.In energy resource consumption, elevator is energy resource consumption equipment most important and maximum in public domain, building simultaneously, is also the important goal equipment that regenerative resource is applied under construction.

The lifting of elevator need to consume a large amount of energy, and its ratio is occupied maximum ratio in whole corridor system.But the regenerative resource supply of elevator in prior art is all the interchange energy supplies that adopt after inversion.Specifically as shown in Figure 1, regenerative resource B elevator technology adopts direct current system (comprising wind-powered electricity generation assembly B1 and/or solar-electricity assembly B2), after energy conversion, by charge controller C, deposit in storage batteries D, and be converted to alternating current by inverter E, for elevator power supply, A provides AC power.And by one group of diverter switch, switch to civil power F when the storage battery quantity not sufficient and power.

Such technology, because the discharging current of storage battery is less, need to configure jumbo storage battery, the electric current supply when guaranteeing that elevator starts.Inverter needs continuous service simultaneously, and with the needs that guarantee that elevator starts at any time, its loss is very big, thereby has further aggravated the configuration of storage battery.Because the useful life of storage battery is limited, thereby prior art is higher for changing the use cost of battery, and produces considerable pollutant sources.Further, its cost is very high, poor reliability, thereby it is quoted seldom.In view of the feature of elevator gap sex work, exchange continued power and can produce a large amount of unnecessary energy resource consumptions; And the interchange conversion that existing elevator adopts is except meeting produces a certain amount of loss, the device that exchanges conversion for civil power is relative complex also, with high costs.These have all limited the application of regenerative resource on elevator, and have further reduced the using value of regenerative resource in corridor, thereby have limited the application of regenerative resource.

Summary of the invention

In view of the defect that above-mentioned prior art exists, the object of the invention is to propose a kind of intelligent energy supply system that elevator adopts regenerative resource that is applied to, solve the comparatively serious problem of elevator loss electric energy in prior art.

Above-mentioned purpose of the present invention, the technical solution of its realization is: the intelligent energy supply system that is applied to elevator, it is characterized in that comprising: administration module, energy unit and energy-storage units, serve as reasons mutually independently super capacitor and storage battery of described energy-storage units forms, and in the connection line of administration module output and the positive interpolar of super capacitor, be provided with in the connection line of super capacitor charging module, administration module output and accumulator positive interpolar and be provided with charge in batteries module, described administration module is for the break-make of program control switching two charging modules; Two anodal being connected formed the energy-storage units discharge path joining with elevator power supply interface module, and two positive interpolars are provided with isolation inductance.

Further, described energy unit is direct current framework, comprises solar energy equipment and wind energy plant, and wherein said wind energy plant is for to be comprised of AC-DC power supply conditioning module and wind-driven generator.

Further, described charge in batteries module is pulse output type charge control module.

Further, the power storage of described energy-storage units has certain redundancy electric weight, and when supplementing without outside energy supply, described redundancy electric weight meets the tram that elevator rests on contiguous floors.

Further, described intelligent energy supply system is also provided with the civil power compensating module of access energy-storage units discharge path, and the control end of described civil power compensating module is connected with administration module.

Further, the protection diode that be equipped with forward conduction between described civil power compensating module and battery positive voltage, oppositely ends.

Apply intelligent energy supply scheme of the present invention, adopt direct current framework to greatly reduce the energy loss causing due to intermediate conversion, super capacitor can provide the instantaneous power of elevator, reduced the demand to storage battery, regenerative resource is carried out accumulation of energy to energy-storage units simultaneously, can guarantee the continual and steady work of elevator, city's electronic compensating has improved elevator and has continued running stability and security performance in addition.

Embodiment

The present invention is directed to the comparatively serious phenomenon of elevator energy loss in the application of prior art regenerative resource, innovation has proposed a kind of intelligent energy supply system that is applied to elevator, adopt the little direct current framework of energy loss to carry out intelligent management to elevator energy supply, solved the problem that in prior art, elevator loss electric energy is comparatively serious, system configuration is complicated and cost is higher.

While generally specifically implementing, by wind energy plant and or solar energy equipment gather natural energy and change into electric energy, by administration module, be that super capacitor and storage battery carry out electric power storage, when elevator starts, the High-current output feature of super capacitor meets the instantaneous power demand of elevator, storage battery is elevator continuous service supplementary power, meets elevator and continues power consumption demand.When energy-storage units energy storage is not enough (when battery tension is reduced to certain threshold values), civil power compensating module can directly provide electric energy by discharge path to elevator.Especially, the protection diode that be equipped with forward conduction between this civil power compensating module and battery positive voltage, oppositely ends.

In addition, this intelligent energy supply system also possesses certain surplus and controls, when energy-storage units closes on, exhaust, civil power when disappearance, the redundancy electric weight of energy-storage units can guarantee that elevator is when operation, rest on the correct floor position of contiguous floors, avoid elevator to hover between floor, improved the fail safe of elevator.

By above-mentioned character express, can find out, apply intelligent energy supply system of the present invention, adopt direct current framework to greatly reduce the energy loss of elevator, super capacitor can provide the instantaneous power of elevator, reduced the demand to storage battery, regenerative resource is carried out accumulation of energy to energy-storage units simultaneously, can guarantee the continual and steady work of elevator, and city's electronic compensating has improved elevator and continued running stability and security performance in addition.

In addition to the implementation, the present invention can also have other execution mode, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the present invention's scope required for protection.
