Embodiment
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
As shown in Figure 1, the hardware configuration of a kind of greenhouse controlled in wireless box of the utility model comprises single-chip microcomputer, voltage detecting circuit, current detection circuit, parallel port expansion module, drives amplifying circuit, wireless communication module, LCD MODULE, power module and button.Single-chip microcomputer is the STC12C5A60S2 single-chip microcomputer, and integrated 10 8 road AD converters possess dual serial equipment interface, house dog and function of keeping secret, satisfy the greenhouse demand for control; Voltage detection module is by exchanging bleeder circuit; Filter rectifier, dc voltage divider circuit is formed, and accomplishes AC-input voltage, DC input voitage and the monitoring of system power supply module voltage; Voltage detection module is to rely on Chip Microcomputer A conversion mouth; And combine self circuit, and converting system's supply voltage value to data, the input single-chip microcomputer is handled; Current detection circuit is to detect interchange or the DC current that flows into control enclosure through Hall element; Mouthful link to each other with the AD of single-chip microcomputer conversion, and port expansion circuit is meant 16 I/O mouths through the expansion of single-chip microcomputer second serial that said driving amplifying circuit is meant through photoelectricity isolation, ULN2803 chip and pull-up resistor etc.; The I/0 of single-chip microcomputer parallel port expansion is put low ABSORPTION CURRENT to be expanded to about 500mA; The wireless communication module of being selected for use is the SZ05 series zigbee wireless communication module that produces along boat scientific & technical corporation, and long transmission distance realizes each control enclosure wireless networking; Guaranteed communicating by letter of each control enclosure and PC; Power module is to convert alternating current or direct current the power supply of single-chip microcomputer and the use of 24V relay into, and guarantees that enough power, button are meant the alternate function key of isolating the access single-chip microcomputer through photoelectricity.
The unit of existing control can be divided into two types, and one type only needs a switching value control like fan, sprinkling irrigation pump, light filling lamp etc., and an object only needs an I/O control port to drive corresponding relay switches to get final product.One type like screen-roller, power sunroof etc., and the control motor needs forward and backward, and such motor can stop when forwarding extreme position to automatically.The special-purpose driver that is equipped with of this type of performance element choosing.Control for first kind switching value; Control enclosure of the present invention provides one to drive mouth; Select a relay that matees with this control enclosure according to voltage, the current conditions of controlling object simultaneously; Relay coil one termination is gone into this control enclosure power module, and an end seals in an I/O control port, forms the relay coil closed-loop path.The controlled device power supply is drawn in control enclosure, is connected in series this relay normally open contact.For second type of motor type controlling object, the driver of selection and control enclosure and driven object motor coupling, and two control lines of controller are inserted the I/O control ports, drive power supply draws and sets the associated drives parameter of control enclosure from control enclosure.
Because all controlling object power supplys of control enclosure all are in control enclosure, to go out, so all object work films, electric current summation are monitored by this control enclosure.When starting a controlling object, the control enclosure electric current can change, and single-chip microcomputer judges according to the size that electric current changes whether this performance element work is normal.For the controlling object like screen-roller or power sunroof, its position that reaches capacity can stop automatically, and control enclosure can be discerned the extreme position whether it arrives motion according to change in current, and all feedback of status are analyzed in the master controller PC.This control enclosure also can to judge that controlling object work has no abnormal according to voltage, the current conditions of self work, reports after can be by oneself for faults such as sudden short circuits again, improves system stability greatly.
The utility model can be used for controlling any one or a plurality of greenhouse performance element; Like screen-roller, fan etc.; Can be according to the difference of controlling object; The scene is set, and need not to carry out before use the change of program, is concrete operations flow process and principle that controlling object details the utility model below with the screen-roller.
Step 1: select corresponding drivers according to controlling object, and the connection hardware circuit, consider that controlling object is a screen-roller; The rotating of motor demand; The 24V driving voltage, thus a H driver that matees with this motor and control enclosure need be chosen, and the control enclosure supply voltage is selected direct current 24V.Control enclosure is installed near the screen-roller motor two power lead access controllers of motor, power supply that wouldn't be driver connected.
Step 2: according to controlling object, the control enclosure parameter is set, energized, start-up control box; Through modifier key on the control enclosure and liquid crystal display prompting, get into driven object and set, at first select screen-roller; After confirming, again according to the recommendation driving I/O port of prompting, before the access with the control line access of two controls of driver; Need further clear and definite port identity, comprising: distinguishing motor is just changeing control line and counter-rotating control line, and puts height and still put basic skill or training's work.
Step 3: after configuring; Press definite key, the parameter of this driving mouth will be stored among the EEPROM of single-chip microcomputer, not lose with the single-chip microcomputer power down; It is each after system powers on; Single-chip microcomputer is all given tacit consent to screen-roller and is in halted state, breaks off the control enclosure power supply, with electric machine controller power supply Access Control box dc power output end.
Step 4: restart control enclosure; Get into this screen-roller control option, can pass through button debugging control motor rotation, whether primary part observation screen-roller open and-shut mode is consistent with the demonstration of control enclosure display screen; Note simultaneously reaching the limit of the position when stopping when screen-roller; Whether the control enclosure display screen shows the screen-roller state, if having difference, Selected Inspection to look into the setting of line and control enclosure.
Step 5: through the option on the liquid crystal display, select to start controlled in wireless, and this state is preserved, so far, this screen-roller control is set and is accomplished.
The PC end telechiric device of a kind of greenhouse controlled in wireless box of the utility model is as shown in Figure 2, is merely a wireless communication module and adaptive working power thereof, and it is connected on the PC through serial ports.This wireless communication module is made as host node, the arbitrary module communication in can the zigbee cordless communication network.PC receives the status information and the transmitting control commands of each control module through this network.
