The central microprocessor is connected with the metering module, the clock chip, the memory, the display unit and the auxiliary terminal signal input circuit respectively. The auxiliary terminal signal input circuit can externally connect with two ways of transformable input signals, representing two different input modes respectively. Based on different input signals accessing to auxiliary terminals, accumulative run time, accumulative total electric quantity, average hourly electric quantity of two different working modes, and average power saving rate and accumulative saved electric quantity after the energy saving reconstruction are recorded respectively, and all the above mentioned data can be displayed and stored.
Description
Technical field
The utility model relates to a kind of instrument and meter, particularly relates to a kind of measuring instrument that is exclusively used in reducing energy consumption.
Background technology
According to " General Office of the State Council transmits the department such as State Development and Reform Commission about accelerating to carry out the notice that Energy Management Contract promotes energy conservation service industry development suggestion " (Office of the State Council is sent out [2010] No. 25) and " National Development and Reform Commission of the Ministry of Finance is about printing and distributing the notice of＜Energy Management Contract finance prize funds management tentative method〉" (wealth is built [2010] No. 249) relevant regulations: complete with the energy measuring apparatus, possess perfect energy statistics and management system, amount of energy saving is measurable, can monitor, verifiable.
Traditional electric energy meter metering method, behind equipment, to install an electric energy meter and a cumulative timer additional, with electric energy meter metering accumulative total electric weight, measure accumulated running time with cumulative timer, many instrument costs are high, and installation volume is large, need manually to calculate power saving rate behind the employing manual metering, the economize on electricity data such as accumulative total amount of energy saving produce the human factors such as the artificial error of calculation and artificial adjustment data easily.
Summary of the invention
Technical problem to be solved in the utility model is for the prior art deficiency, to provide a kind of metering safety, accurate, electric energy meter easy to operate, that can be used for measuring reducing energy consumption front and back energy-saving effect.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of measuring instrument that is exclusively used in reducing energy consumption, it is characterized in that, comprise central microprocessor, metering module, clock chip, storer, display unit and auxiliary terminal signal input circuit, described central microprocessor is connected with metering module, clock chip, storer, display unit, auxiliary terminal signal input circuit respectively; Described central microprocessor signal input part connects the input signal of auxiliary terminal; Described auxiliary terminal signal input circuit connects the input signal that two-way can be changed.
As preferred embodiment, described auxiliary terminal signal input circuit comprises two parallel connection input branch roads that structure is identical, described input branch road mainly is comprised of power supply, optic coupling element, and power supply is connected with optic coupling element, and described two input branch roads all are connected with central microprocessor; Two input branch roads respectively are connected to a pair of auxiliary terminal.
Compared with prior art, the beneficial effect that the utility model has is: the utility model is by accumulated running time, the accumulative total total electric weight of central microprocessor in the ammeter according to the automatic calculating of input signal and memory load, and can calculate and store on average per hour electric weight, by display unit result of calculation is shown.Be connected with the auxiliary terminal signal input circuit with the central microprocessor input end, auxiliary terminal can external two-way input signal, represent respectively two different input patterns (transforming front and improved mode of operation), difference according to auxiliary terminal access input signal, can record respectively under two kinds of different working modes accumulated running time, the total electric weight of accumulative total, mean hours electric weight, the average power saving rate after the reducing energy consumption and the accumulative total amount of electricity saving of (before transforming and after transforming).

Embodiment
As shown in Figure 1, the structural drawing of the utility model one embodiment is equipped with central microprocessor, metering module, clock chip, storer, display unit and auxiliary terminal signal input circuit in electric energy meter inside.Wherein, central microprocessor is connected with metering module, clock chip, storer, display unit, auxiliary terminal signal input circuit respectively.
As preferred embodiment, the auxiliary terminal signal input circuit comprises two parallel connection input branch roads that structure is identical, and described input branch road mainly is comprised of power supply, optic coupling element; Power supply is connected with optic coupling element.Described two input branch roads all are connected with central microprocessor; Two input branch roads respectively are connected to a pair of auxiliary terminal.The auxiliary terminal signal input circuit can external two-way input signal, represents respectively two different input patterns: pattern one signal and pattern binary signal (before namely transforming and improved mode of operation).
The auxiliary terminal signal input circuit of the utility model one embodiment provides the two-way input signal, represents respectively two kinds of different input patterns (namely transforming front and improved mode of operation).Use pattern one input signal before reducing energy consumption is carried out in load is automatically calculated according to input signal and memory load equipment accumulated running time, total electric weight totally by central microprocessor in the ammeter, and can calculate, stores and show on average per hour electric weight.After reducing energy consumption is carried out in load, with input signal manual switch two input signals that become the mode, at this moment, central microprocessor in ammeter automatically calculate according to input signal and the memory module two-state under load equipment accumulated running time, total electric weight totally, and can calculate, store and show on average electric weight per hour under this pattern.Auxiliary terminal is in case transfer pattern two to from pattern one, and the ammeter internal processes is the cancellation of pattern one running status, and ammeter pattern one state that can not rerun prevents artificial cheating.Last central microprocessor calculates, stores by the data under two kinds of different modes of storage and shows average power saving rate and accumulative total amount of electricity saving after the reducing energy consumption.Compare with traditional metering method, it is high that the utility model electric energy meter has overcome many instrument costs, installation volume is large, need to adopt manual metering, artificial calculating produces the defectives such as personal error easily, security and the accuracy of metering have been improved, Energy-saving Data just can show on measuring instrument, and is simple to operate, easy to use.
