Energy consumption data relatively

$\mathrm{\Δ}{Q}_t=Q_a-\frac{\underset{t=1}{\overset{n}{\mathrm{\Σ}}}{Q}_t}{n}$(formula 1)

In the formula 1, Qa is a current time power consumption among the regional a, and Qt is historical same period of the power consumption of the same area synchronization, and n representes the number of historical same period of data.The Δ Qt that calculates thus is the difference of current power consumption and the history power consumption same period.This comes to confirm current power consumption state through this difference and the baseline threshold of presetting.The setting of threshold value can rule of thumb manually be provided with by the user, also can be default by software according to computes:

$K_t=\frac{\underset{t=1}{\overset{n}{\mathrm{\Σ}}}{\mathrm{\Δ\; Q}}_t}{n}$(formula 2)

In the formula 2, Δ Qt is the t current year and a prior year historical data variable quantity constantly.Therefore draw threshold k t, be t average energy consumption data variation amount over the years constantly.Simultaneously, can find out that when having new energy consumption data to be write down the historical energy consumption data of generation, this threshold value is all upgraded Automatic Optimal by formula 2.When | Δ Q_t|≤| K_t| the time, judge that the energy consumption of this zone current time is normal; When | Δ AQ_t|＞| K_t| the time, judge that then the energy consumption of this zone current time is unusual.

Normal lighting, emergency lighting, elevator etc. in air-conditioning, common socket power consumption, the zone, these equipment all use independently current supply circuit usually, and power consumption can be by independently transferring to the energy consumption acquisition module through serial ports or Ethernet after the ammeter metering.Controlled subsystem can be opened control interface and give the intelligent building integrated system.Common air-conditioning system, illuminator, elevator devices etc. have all been opened open/close control interface and have been given the intelligent building integrated system.Therefore the energy consumption of these subsystems source all belongs to controlled energy consumption.Simultaneously, also there is the not open control interface of some subsystems to give the intelligent building integrated system, like emergency lighting, daily socket power supply etc.These energy consumption sources belong to uncontrollable energy consumption.For controlled energy consumption, the suggestion user closes operational outfit, or equipment is switched to the low-power consumption energy saver mode.When for example not having the personnel activity in the office, can close air-conditioning, normal lighting etc.The energy-conservation knowledge base that presets through inquiry simultaneously, the device characteristics of originating according to energy consumption also can propose to optimize suggestion.For example air conditioner filter screen cleans, the aging need of motor are lubricated etc.For uncontrollable energy consumption, enumerate out all uncontrollable energy consumption sources, this zone, supply this uncontrollable energy consumption of customer inspection whether reasonable.If unreasonable, should give and eliminate the energy consumption source.Perhaps require subsystem to provide control interface, should uncontrollable energy consumption change controlled energy consumption into to the intelligent building integrated system.

As shown in Figure 3, control model comprises automatic mode, a key energy saver mode and subitem manual mode.Automatic mode need not to intervene manually, according to energy consumption control analysis result, automatically controlled energy consumption is implemented control by the real-time energy-conservation linkage control device of intelligent building.One key energy saver mode is enumerated out all controlled energy consumption source and control modes by the real-time energy-conservation linkage control device of intelligent building; Do not carry out concrete control operation; After user's affirmation and manually selecting a key power saving function, just all control operations of disposable execution of the real-time energy-conservation linkage control device of intelligent building.Subitem is control manually; The real-time energy-conservation linkage control device of intelligent building is enumerated out all controlled energy consumption source and control modes; The user can select whether to confirm to implement control item by item, and the user can carry out Combinatorial Optimization to specific a certain item or a few control modes thus.

As shown in Figure 4, the present invention's control strategy closing device of taking to delay time after energy consumption equipment Be Controlled system closing, still allows personnel's manual unlocking, to remedy issuable erroneous judgement when utilizing video monitoring system to carry out personnel activity's state analysis.If equipment is by manual unlocking, the real-time energy-conservation linkage control device of intelligent building will judge whether closing device once more behind preset delay time.After if time-delay finishes, system judges that these regional real time energy consumption data and historical data contrast no longer are in ERST, then cancel time-delay closing control.After if time-delay finishes, the real-time energy-conservation linkage control device of intelligent building judges that this regional energy consumption real time data still is in ERST, once more closing device.The equipment that is fit to this strategy includes but not limited to air-conditioning, normal lighting, elevator, projector, sound equipment etc.

Those skilled in the art do not break away from essence of the present invention and spirit; Can there be the various deformation scheme to realize the present invention; The above is merely the preferable feasible embodiment of the present invention; Be not so limit to interest field of the present invention, the equivalent structure that all utilizations instructions of the present invention and accompanying drawing content are done changes, and all is contained within the interest field of the present invention.
