Embodiment
Be described in detail below in conjunction with the embodiment of accompanying drawing to intelligent electric meter of the present utility model.
As shown in Figure 1, be the structural representation of the intelligent electric meter of one of them embodiment, a kind of intelligent electric meter comprises:
Main control chip 101, IC-card sensor circuit 102, voltage processing circuitry 103, at least plural electric energy computation chip 104, storer 105;
The output terminal of described voltage processing circuitry 103, IC-card sensor circuit 102, each electric energy computation chip 104 and storer 105 are connected with described main control chip 101 respectively; The input end of described voltage processing circuitry 103 connects voltage signal; Each electric energy computation chip 101 is connected with described storer 104 respectively.Voltage processing circuitry 103 is connected on power transmission line, and main control chip 101 is mainly used to control cooperatively interacting of each element, jointly realizes the functions such as the calculating of information about power, storage and inquiry, and main control chip 101 adopts product ripe on the market at present; Information about power on subscriber card for responding to subscriber card, and is read on ammeter by IC-card sensor circuit 102; Electric energy computation chip 104 is for calculating the power consumption information of user and being stored to storer 105; Storer 105, for the power consumption information of user being stored, is convenient to user's inquiry.
Above-mentioned intelligent electric meter, a main control chip connects at least plural electric energy computation chip simultaneously, achieves single instrument to the control of multiple user power utilization amount and management, reduces the electric cost of user; And, because each user of same collective unit need not independent wiring, also reduce the difficulty of comprehensive wiring.
As shown in Figure 2, be the structural representation of the intelligent electric meter of another embodiment, a kind of intelligent electric meter can also comprise clock chip 106, for showing the current time.
Wherein in an embodiment, intelligent electric meter can also comprise back-up storage chip 107, for the power consumption information of the multiple users calculated with storage of electrical energy computation chip 104 that back up in realtime, is convenient to user's inquiry.
Wherein in an embodiment, intelligent electric meter can also comprise display 108, for showing power purchase information, the power information and dump energy information etc. of multiple user in turn.
Wherein in an embodiment, intelligent electric meter can also comprise button 109, for switching the display interface of the different user power consumption information on ammeter.
Wherein in an embodiment, intelligent electric meter can also comprise communication interface 110, for incoming communication equipment, realizes long-range function of checking information on multiple subscriber card; Wherein, communication interface 110 can be any one in infra red communication port, TCP/IP communication interface or RS485 communication interface.
Wherein in an embodiment, intelligent electric meter can also comprise power supply 111, for powering for intelligent electric meter; Wherein, power supply 111 is rechargeable batteries.
The electric energy computation chip of multiple user is accessed the mode on same control chip by intelligent electric meter employing of the present utility model simultaneously, realize the unified of multi-user power-driven amount to control and management, not only reduce the complexity of construction, more reduce the cost of consumer, and then reduce the electric cost of user.
Access the user of intelligent electric meter of the present utility model, single-phase number of users and three-phase number of users can independent assortments, such as, realize the management of power use of a road three-phase user and the single-phase user in 21 tunnels simultaneously, the instrument volume on 24 tunnels is only 450 × 160 × 100mm, this dramatically reduces the volume of ammeter, reduce the difficulty of comprehensive wiring.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this instructions is recorded.
Apply intelligent electric meter of the present utility model, after carrying out corresponding improvement, the loading condition of real-time supervisory user can also be used for, such as, when monitoring user and accessing bad load, the function cutting off the power supply of this user is immediately set, realizes power supply by keeper or user card punching afterwards, and this situation is recorded in ammeter, in order to inquiry later; Can realize forcing power-off and forcing power transmission simultaneously; Forced interruption, namely in order to avoid the accident that circuit during accident can bring, ignores the value of residue electric degree, forced interruption; Forced power transmission, namely ignores the value of residue electric degree, forced power transmission, but still carries out watt metering, if the value of residue electric degree is less than or equal to 0, so remaining electric degree will measure for negative value always, deduct when treating to pay the fees next time.Wherein, bad load recognition principle is: when change appears in user load, the power and power factor that increase part load is measured by ammeter, because the power factor of the resistive load of electric cup and so on is higher, reach more than 0.99, again by judging the power increased, namely the two identify bad load and carry out power-off control.
Apply intelligent electric meter of the present utility model, timesharing multi tariff function and step price function can also be realized.Timesharing multi tariff can be divided into several period by one day, and each period, step price, was set to several grade by the power consumption of month, and the part exceeding a certain grade carries out charging by the electricity price of correspondence by an electricity price charging; Thus realize the steps calculating of demand charge.
