Fig. 2 is microcontroller circuit figure of the present utility model；
Fig. 3 is regulator circuit diagram of the present utility model；
Fig. 4 is driving relay circuit figure of the present utility model；
Fig. 5 is that USB of the present utility model turns serial ports download circuit figure.
Embodiment
A kind of zigbee control device of wireless as shown in Figures 1 to 5, it is characterised in that：Including zigbee communication modules,
Microprocessor, USB turn serial ports download circuit, serial ports switching switch, regulator, driving relay circuit and relay
Device；Described microprocessor turns serial ports download circuit with zigbee communication modules and USB respectively by serial ports switching switch and is connected,
Described microprocessor is connected with regulator and driving relay circuit；Described driving relay circuit and relay
Device is connected.
Described microprocessor uses STC89C52 type single-chip microcomputers.
Described regulator is using LM2596 step down supplies management monolithic integrated optical circuit.
Described driving relay circuit is using high withstand voltage, high current Darlington ULN2003.
Described zigbee wireless communication modules select SZ05-ADV-SMA modules.
Described USB turns serial ports download circuit and turns serial port chip using CH340G USB.
Wherein zigbee communication modules are connected with microprocessor using serial ports, and USB turns serial ports download circuit and microprocessor
It is connected using serial ports, system switches switch by serial ports and realizes both time-sharing multiplexs to serial ports using row's pin switching.During download
USB turns download circuit work, and zigbee communications stop；Zigbee works during radio communication, and USB turns serial ports stopping.STC89C52
Minimum system is the core of the reception order carry out system control of system, and USB turns serial ports download circuit, can be by compiled journey
Sequence direct burning on the chip of system board, select along boat science and technology SZ05-ADV-SMA modules, should by zigbee wireless communication modules
Module provides serial interface, and single-chip microcomputer only needs to connect the module by serial ports, it is possible to realizes and the data of the module communicate.
Single-chip microcomputer passes through the direct control that drives ULN2003 to complete to relay.The electricity needed due to relay adhesive
Stream single-chip microcomputer can not meet, therefore control in this way, and the mode of non-traditional triode, the discrete member of traditional mode
Device is more, the stability and poor reliability of system.Electric power management circuit is inputted using Width funtion（Input voltage 5V-40V）, output
Voltage 5V, Width funtion input can be readily Systematic selection adapter, and the onboard CH340G USB of system turn serial port chip, convenient
Renewal of the engineering staff scene to system, using ULN2003 drive circuits, allow the operation that system can be reliable and stable, use
Zigbee controlled in wireless because zigbee support networking, belong to industrial general radio band and with single chip communication interface letter
It is single.
System uses the power management chip LM2596 of Width funtion input, and the power management chip disclosure satisfy that system to electricity
The parameter request in source, and workmen can be allowed and quickly find suitable adapter for system.LM2596 circuits use
Typical circuit on LM2596 databooks, the circuit can provide the operating voltage and peak that ripple factor is less than 200mV for system
It is worth the electric current for 3A.The control core of system is from the preferable STC89C52 single chip of STC Corporation's compatibility；Due to
STC89C52 single chip can not directly drive relay, therefore system drives relay circuit using ULN2003, ULN2003's
Single pin can drive 500mA electric current, and the download circuit requirement that USB turns serial ports is realized using CH340G chips, convenient
Engineering staff carries out sassafras to chip on circuit boards and write, in order to realize that system is capable of the reliability of networking and radio communication, this reality
With the new zigbee modules using along boat science and technology, single-chip microcomputer and the module use serial ports transparent transmission.
