Technical field

The utility model relates to a kind of corollary apparatus of water system, and in particular, the utility model relates generally to a kind of intelligent booster water management system.

Background technology

At present, it is the FPGA (Field Programmable Gate Array) controller that pressurized water supply industry majority has adopted PLC() as the constant pressure water supply controller, and technology is relatively ripe.This quasi-controller has been simplified much at the Control before relative on the electrical structure, but the expanded function of its all kinds of logical operation signal outputs lacks dirigibility, the dynamic property of system and stability still are not too high, be difficult to realize data communication with other supervisory system and configuration software, and then and limited load-carrying capacity, therefore will be restricted in actual use age scope.Especially control strategy and above the algorithm because therefore the restriction of hardware and software can't carry out larger technological improvement for supercharging water supply system based on programmable logic controller (PLC).

The utility model content

One of the purpose of this utility model is to solve above-mentioned deficiency, a kind of intelligent booster water management system is provided, solve in the prior art not high because of PLC controller dynamic property with expectation, and because its intrinsic example, in hardware has limited its control strategy and algorithm, so that can't the technical matters such as make further improvements to the intelligent functions of supercharging water supply system based on PLC.

For solving above-mentioned technical matters, the utility model by the following technical solutions:

A kind of intelligent booster water management system provided by the utility model, comprise the analog input module, analog output module and be used for carrying out switching signal, the control module of analog signals logical process, and analog input module and respectively Access Control module of analog output module, described control module is the ARM controller, also comprise switching value output module in the described water system, photoelectricity Isolation input module and driver module, and switching value output module, photoelectricity Isolation input module and driver module access the ARM controller respectively.

Further technical scheme is: described driver module also accesses touching display screen, and is provided with corresponding operation signal input interface between ARM controller and the driver module.

Further technical scheme is: described ARM controller also accesses the RS-485 communication module, and RS-485 communication module access RS-485 communication bus, comprises at least the MAX485 interface chip in the described RS-485 communication module.

Further technical scheme is: also be provided with the Ji tag interface for each class method input or debugging on the described ARM controller.

Further technical scheme is: described analog input module and analog output module also access respectively outside frequency converter and variable valve.

Further technical scheme is: export core take relay as it in the described switching value output module.

Further technical scheme is: described photoelectricity Isolation input module also accesses external pressurization equipment.

Compared with prior art, the beneficial effects of the utility model are: replace the PLC programmable logic controller (PLC) by adopting the ARM controller, because the ARM controller can be used for carrying out the logical program of most computer software algorithm, therefore can realize the high precision control of supercharging water supply system, and ARM controller and all kinds of program logic computers is better compatible, can make up the more intelligent functions of supercharging water supply system based on the ARM controller, and need not by peripheral interface unit by the RS-485 bus, can realize data remote control with other control system, be easier to other system integrated, and a kind of intelligent booster water management system provided by the utility model is simple in structure, can directly utilize existing PLC pressurized water supply control system to reequip in the necessary situation, range of application is wide.

Description of drawings

Fig. 1 is for being used for the system architecture diagram of explanation the utility model embodiment.

Embodiment

Below in conjunction with accompanying drawing the utility model is further elaborated.

ARM(Advanced RISC Machines) processor is that Acorn computing machine company limited is towards the first item risc microcontroller of low budget Market Design.

Fig. 1 shows structured flowchart of the present utility model, with reference to shown in Figure 1, an embodiment of the present utility model is a kind of intelligent booster water management system, comprise the analog input module, analog output module and be used for carrying out switching signal, the control module of analog signals logical process, and analog input module and respectively Access Control module of analog output module, described control module is the ARM controller, also comprise switching value output module in the described water system, photoelectricity Isolation input module and driver module, and switching value output module, photoelectricity Isolation input module and driver module access the ARM controller respectively, and the ARM controller of mentioning in the present embodiment is take the ARM9 chip as core.

The effect of above-mentioned analog input module is the pressure transducer with outside need control, input ARM controller operation after the conversion of the analog quantitys such as flow sensor.The effect of analog output module is the data after the computing of ARM controller to be passed to the external units such as frequency converter and variable valve control.The effect of switching value output module is that the logic of ARM controller calculation process is exported by relay.The effect of photoelectricity Isolation input module is that the state with external unit inputs to the ARM controller.

Again with reference to shown in Figure 1, the utility model is on above-mentioned basis for a kind of embodiment that the technical solution problem is more preferably, driver module is accessed touching display screen, and be provided with corresponding operation signal input interface between ARM controller and the driver module.And above-mentioned ARM controller can also access the RS-485 communication module, and RS-485 communication module access RS-485 communication bus, comprises at least the MAX485 interface chip in the described RS-485 communication module.

According to another embodiment of the present utility model, with the Jitag interface that also is provided with on the above-mentioned ARM controller for each class method input or debugging.And plan amount load module and analog output module also access respectively outside frequency converter and variable valve.

And above-mentionedly also mention, for so that switching value output module and the corresponding effect of photoelectricity Isolation input module performance should export core as it with relay in the switching value output module, and photoelectricity Isolation input module also access external pressurization equipment.

Use procedure of the present utility model is as follows: the effect that shows according to the implementation of touch display, the data of each collection are all regulated the ideal value that draws by PID, the control signal of PID control system output must in time be adjusted according to the state of control object, in order to keep the stable of control object state, so the status information of real-time grasp control object is very important, these information can be empirical values, it is the classical value of the net assessment of some control effects that put into operation, these value error rates are very low, can objectively respond out control system control effect, passing through classical PID adjustment module control algolithm, make value infinite approach ideal value, allow whole control system enter a desirable duty.Because these software systems need Real-time Collection, requirement of real-time is very high, carries out visual programming so used UC-OSII operating system, establishes the variation of system call task, in the cycle of each task scheduling, can allow CPU be in best working load state.Clock period is set in 10MS once, and like this, scheduling is got up, and the ideal that can allow system move can allow again CPU can not enter sleep state when having tasks carrying, reaches the effect of power and energy saving.
