Embodiment
As shown in Figure 1, the utility model comprises control module, Zigbee wireless communication module, buzzer warning module, light regulation and control module and relay module.Control module and Zigbee wireless communication module are realized by single-chip microcomputer CC2530.Relay module provides four control relay circuits, is respectively used to control electrically driven curtain front wheel driving motor, electric rolling rear drive motor, air exhauster and electromagnetic water valve.Light regulation and control module comprises zero-detection circuit and brightness regulating circuit.Can be applicable in Smart Home or reading intelligent agriculture system, by Zigbee wireless communication protocol, receive the data from multiple sensors, gather the real time environment parameter in agricultural greenhouse, and regulate and control plurality of devices, thereby realize the adjusting to crop growth environment in booth.
Electric rolling, electromagnetic water valve, air exhauster are all to pass through Control.Control relay circuit of the present utility model as shown in Figure 2, because the port current of CC2530 is too small, cannot drive relay, thus use ULN2803 as driving chip, with respect to using triode to drive, more stable and easy with chip.When control port (the I/O port P04~P07 on single-chip microcomputer) is high level, ULN2803 delivery outlet is low level, and relay conducting and LED lamp are bright; Otherwise relay disconnects.By the break-make of two relays, control the switch of 220v electric rolling motor, air exhauster and electromagnetic water valve.
As shown in Figure 3 and Figure 4, incandescent lamp light regulation and control module comprises zero-detection circuit and brightness regulating circuit.Use bidirectional triode thyristor to carry out brightness control, by detecting the zero point of alternating current, thereby different opening time-delaying brightness adjustings is set.Civil power is the sine wave of 50HZ, and zero-detection circuit is used the conducting of triode Q1 and off-state to produce a level variation.When alternating current approaches null position, because resistance R 2, very little by the electric current in TPL1 optocoupler left side, optocoupler disconnects, and makes triode Q1 base voltage for high, triode Q1 conducting, and the P20 port of single-chip microcomputer produces a low level; Otherwise, optocoupler conducting, triode Q1 base earth, triode disconnects, and the P20 of single-chip microcomputer is high level.By a rising edge is set, interrupt, the zero point of alternating current can be detected.[note: T0.6-03 is the transformer that 220v turns 12v.The selection of resistance R 2 is very important, if excessive, electric current is less, and when alternating current does not approach zero point, optocoupler just disconnects, and causes detect zero point inaccurate; If too small, electric current is bigger than normal, and the interval at zero point of alternating current is too narrow, causes the P20 low level state retention time too short, cannot detect.】
As shown in Figure 4, when control port (the I/O port P01 on single-chip microcomputer) is low level, triode Q2 conducting, the collector of triode has electric current, optocoupler MOC3021 left side trigger circuit turn-on, the anode of bidirectional triode thyristor is communicated with base stage, if there is trigger current, controlled silicon conducting is until the electric current at negative and positive the two poles of the earth is 0, and controllable silicon just disconnects.If P01 is high level, controllable silicon disconnects.So can the time delay of trigger current be set by the alternating current zero point detecting, regulate the ON time length in a sine wave period, thereby regulate incandescent lamp brightness.[the low level retention time of note: P01 can not surpass the cycle (0.02s) of alternating current, otherwise controllable silicon conducting always.】
By the functional universal controller based on Zigbee of the present utility model, based on Zigbee wireless communication technology, networking flexibility, favorable expandability, low in energy consumption, can pass through neatly computing machine, smart mobile phone or ARM controller equiment, realize the control to a plurality of equipment, can be widely used in the Internet of Things application systems such as Smart Home, reading intelligent agriculture.
