In order to be applicable to other occasions, the utility model also is provided with the circuit of RS232 communication interface 8 and RS485 communication interface 9, can adapt to on-the-spot various signal access and can make things convenient for and various instrument and equipment forming control system.
As Fig. 2～shown in Figure 3, the central control unit of intelligence control circuit is selected the MSP430 microcontroller for use in the present embodiment, is the core of entire circuit, and FLASH program storage that it is inner and E2PROM storage are used for program code stored respectively and the Control Parameter variable; Adopt the GSM/GPRS module SIM300C of the embedded ICP/IP protocol stack of SIMCOM company, this functions of modules is powerful, simple to operate, cost performance is high.MSP430 links to each other with sim card socket with SIM300C with mother daughter board connector by P2.5～P2.7, P3.0～P3.4, and wherein P2.6 is connecting the PWRKEY pin of SIM300C, with the switching on and shutting down of control SIM300C.The MSP430 microcontroller is according to program-code executable operations in the program storage, with GPRS transceiver communication module SIM300C, the next feedback data calculation process of position sensor of valve, and the signal that will export is put into and carries out motor and button, display operation on the I/O of chip, and the data that will preserve are saved in the specified memory goes.The SIM300C module is that the physical layer of carrying out the tcp/ip communication agreement guarantees, its main task is that the digital signal with MSP430 microcontroller serial form becomes GPRS wireless signal and output, or wireless signal is become MSP430 microcontroller serial form digital signal is input to the MSP430 microcontroller.
As Fig. 4～the Figure 5 shows that relay circuit of the utility model driver element and the connecting circuit of bidirectional triode thyristor and motor, the P4 mouth of MSP430 microcontroller is connected with in turn by photo coupler (by A1～A8 mouth), relay (DO1A～DO8A) and bidirectional triode thyristor, resistance, the electric-motor drive unit circuit that electric capacity is formed, described electric-motor drive unit just comprises, reverse two group relay driver modules and just, reverse two groups of controllable silicon driver modules, just, the output terminal correspondence of reverse two group relay driver modules just is connected in, the control end of reverse two groups of controllable silicon driver modules; Described forward and reverse two group relay driver modules include three relays for every group, with every group of included three controllable silicons corresponding connection respectively of described forward and reverse two groups of controllable silicon driver modules, corresponding with the three phase terminals of the motor respectively connection of three controllable silicons of described forward controllable silicon driver module, three controllable silicons of described reverse controllable silicon driver module correspondence in parallel is connected in the three phase terminals of motor.The drive signal of motor-drive circuit output is linked into AC induction motor 2, drive speed reducer 3 to output shaft 4, simultaneously feedback signal 7 is fed back to the MSP430 microcontroller by analog amount input 11 and switching value input 10, and control valve action after controller inside is to its signal processing.
Concrete working procedure of the present utility model is as follows: the digital quantity of the position feed back signal that given analog amount of 4～20mA valve location that actuator is given with the GPRS controller of upper attitude or switching value and actuator itself produce after by the A/D converter digitizing of MSP430 microcontroller inside all is input to the MSP430 microcontroller, and with two digital quantity computings, relatively, whether error in judgement is within the accuracy rating of setting, if in the switching signal of then not exporting the control motor rotation, if not then will be according to being that positive error or negative error decide the positive turn-off of output to close signal or reversal switch signal.Two optocouplers of switching signal control of motor, whether the conducting of optocoupler output terminal determines the relay conducting of back still to close, reaching the control motor is running or the purpose that shuts down, thereby realizes the action control to valve.
SCM program of the present utility model uses the C51 language compilation, adopt top-down modular design method, whole procedure comprises that system initialization, serial ports send, serial ports interrupts function sub-modules such as reception, GPRS communication, LCD demonstration, button reception, warning.In the application program, communicate by letter by the establishment and the decomposition of communication submodule realization tcp/ip message frame with the SIM300C module protocol.
The utility model has been owing to adopted the GPRS communication system, the degree of regulation height, and intelligent degree height, thereby have following outstanding advantage than original actuator: (1) on-the-spot supplementary equipment of using is lacked.After adopting the GPRS communication modes, do not need communication cable, and need not any isolation and conversion and input/output module, reduced a large amount of signal cables, saved hardware such as corresponding wire way, electric closet, reduced expense, but also convenient field connection; (2) reliability height.Adopt the GPRS communication, it is output as digital signal.This comes than just having made a world of difference with traditional final controlling element that is output as analogue signal, has not only reduced the loss in the signal conversion process, increased antijamming capability, and the quality of signals of transmitting also is very reliable and stable.Use GPRS intelligence actuator to reduce a large amount of wiring work and a large amount of middle transition devices, therefore also reduced a large amount of mistakes and the system failure; (3) convenient operating maintenance.Adopted the GPRS communication, has bidirectional communication function, operator both can demarcate on-the-spot actuator in the control room, parameter setting, function configuration, but the working condition of on-Line Monitor Device also, row fault diagnosis and accident forecast, enforcement state maintenance no longer need picture must go to the scene in the past.Because actuator is in monitored state constantly, so operation and maintenance is very convenient; (4) can realize remote programmable, operation and diagnosis.When some insoluble problems have appearred in actuator at the scene, just can utilize the ethernet communication network to carry out remote medical consultation with specialists, producer needn't arrive on-the-spot; (5) town water supply, air feed, heating, effluent discharge, industry water seedbed, geographical position such as petroleum pipeline disperse to use, distance between automation equipment and the electric valve can reach tens of kilometer, the cabling difficulty greatly in addition cannot, single the utility model has just solved this class difficult problem.
Above content description basic principle, working procedure and the advantage of the utility model preferred implementation; be for the ease of understanding; under the prerequisite that does not break away from the utility model spirit and scope; similar changes and improvements all fall in the claimed scope of the utility model, but are not limited to the restriction of present embodiment.
