The circuit diagram of a kind of intelligent electric energy meter that Fig. 2 provides for the utility model embodiment 1 Sorry, your ticket has not enough value warning circuit.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.Further, following embodiment is possibility of the present utility model, embodiment put in order and embodiment numbering execution sequence preferred with it have nothing to do.
Embodiment
Intelligent electric power meter hardware structural representation shown in the present embodiment composition graphs 1, a kind of intelligent electric energy meter is provided Sorry, your ticket has not enough value warning circuit, this circuit is divided into intelligent electric energy meter main circuit and peripheral adapter circuit in the present embodiment, wherein, intelligent electric energy meter main circuit is the same with the main circuit of intelligent electric energy meter of the prior art, seldom describes in the present embodiment; Peripheral adapter circuit, as shown in square frame in Fig. 2, mainly comprises audible alarm circuit 10, preferably, also comprises light warning circuit 20.
As shown in Figure 1, what the single-chip microprocessor MCU in main circuit adopted is 80C51 single-chip microcomputer of the prior art, the communication module in left side contains PLC (Programmable Logic Controller, programmable logic controller (PLC)) carrier communication circuit and 485 telecommunication circuits, dissimilar intelligent electric energy meter can be adapted to, such as there is the electric energy meter PLC carrier communication circuit of carrier wave function to read data, do not have the electric energy meter of carrier wave function 485 telecommunication circuits to read data.Power circuit, RS232 communication interface, 485 telecommunication circuits be with PLC carrier communication circuit all with prior art in the same, do not repeat in the present embodiment.
With reference to the main circuit schematic diagram of the whole intelligent electric meter shown in Fig. 2, audible alarm circuit 10 (circuit in Fig. 2 in square frame) and the light warning circuit 20 as peripheral adapter circuit in figure, can also be seen.
Wherein, audible alarm circuit 10 comprises: power Vcc, triode Q200, the first diode D200, the second diode D201 and loudspeaker Sp200.Triode Q200 is PNP type triode; First diode D200 is light emitting diode, such as red LED.
Power Vcc is connected with the emitter of PNP type triode Q200; The base stage of PNP type triode Q200 is connected with the first diode D200, and the collector of PNP type triode Q200 is connected with the second diode D201; Ground connection after second diode D201 is in parallel with loudspeaker Sp200; First diode D200 is connected with the P15 pin of intelligent electric energy meter main circuit.Because intelligent electric energy meter main circuit of the prior art also can produce alerting signal when Sorry, your ticket has not enough value, therefore only need to be connected can to realize audible alarm with the P15 pin of main circuit.Namely, when Sorry, your ticket has not enough value, the alerting signal of generation is by after the second diode D200, and luminescences such as LED, and make triode Q200 conducting, the electric signal of generation makes its sounding alarm by loudspeaker Sp200.Preferably, a resistance R200 (resistance 1K) can also be connected to protect audible alarm circuit between D200 and P15.
The access of tut warning circuit solves the poor technical matters of warning reminding effect that electric energy meter in prior art causes by means of only light warning, and then can realize improving warning dynamics, no matter whether electric energy meter is placed in outdoor all can obtain that Sorry, your ticket has not enough value in time warning message, the obvious technique effect of type of alarm.
As shown in Figure 2, in preferred version, the present embodiment further comprises light warning circuit 20, and the special feature of the light warning circuit in the present embodiment is many light warning branch roads, and many light warning branch roads connect the light emitting diode of different colours respectively.So just, can different light colors be used to report to the police according to the different remaining sum stages, so that user identifies which stage is current electric energy meter remaining sum be in.Are three light warning branch roads with many light warning circuit branch, after three light warning branch circuit parallel connections, one end is connected with power supply, other end ground connection.In concrete connected mode light warning circuit as shown in Figure 2, one end of the resistance R13 (resistance 1K) of Article 1 light warning branch road is connected with power Vcc, after the other end is in parallel with intelligent electric meter main circuit by the P20 pin of intelligent electric meter main circuit, connect with the light emitting diode H2 of redness, red light emitting diode H2 ground connection.One end of the resistance R14 (resistance 1K) of Article 2 light warning branch road is connected with power Vcc, the other end is connected with green light emitting diode H3 with after the parallel connection of intelligent electric meter main circuit by the P21 pin of intelligent electric meter main circuit, green light emitting diode H3 ground connection.One end of the resistance R15 (resistance 1K) of Article 3 light warning branch road is connected with power Vcc, the other end is connected with yellow light emitting diode H3 with after the parallel connection of intelligent electric meter main circuit by the P22 pin of intelligent electric meter main circuit, yellow light emitting diode H2 ground connection.
The light of the same color in same circuit is all adopted to report to the police because which is intelligent electric energy meter main circuit remaining sum of the prior art be in stage, therefore user cannot be given remaining sum warning message accurately, the light warning circuit that the present embodiment provides, can according to the light warning of generation of different remaining sum stages different colours, be convenient to user distinguish, improve warning effect dynamics.Use with audible alarm circuit, warning effect is better simultaneously.
Above, be only embodiment of the present utility model, but the utility model can have multiple multi-form embodiment, by reference to the accompanying drawings the utility model is illustrated above, this does not also mean that the embodiment that the utility model is applied can only be confined in these specific embodiments, those skilled in the art should understand, embodiment provided above is some examples in multiple preferred implementation, the embodiment of any embodiment the utility model claim all should within the utility model claim scope required for protection, those skilled in the art can modify to technical scheme described in each embodiment above, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent to replace or improvement etc., within the protection domain that all should be included in the utility model claim.
