The wireless remote monitering and the control system that are used for tap water supply system
The utility model relates to secondary water-supply pressurized equipment field, relates in particular to a kind of wireless remote monitering and control system that is used for tap water supply system.
Traditional non-negative pressure water-supply installation control system adopts frequency converter, PLC, touch-screen, compositions such as driving circuit.There is failure logging but and the non-fault feedback function on the composition; Even have feedback function; Can not let device operator and user know anywhere or anytime, often not have good forewarning function for important water system with for unattended water system.And traditional network service cost of investment is big, installs complicatedly, and operation is difficult for, can not carry out whenever and wherever possible controlled with check.
The utility model content
The purpose of the utility model is that to solve traditional network service cost of investment big, installs complicatedly, and operation is difficult for, and control singlely, can not carry out controlled whenever and wherever possible and problem that check; And a kind of wireless remote monitering and the control system that is used for tap water supply system that provides.
For realizing above purpose; The technical scheme that the utility model adopts: a kind of wireless remote monitering and control system that is used for tap water supply system; It is characterized in that: this wireless remote monitering mainly is made up of three parts with control system; First is a mechanical floor, and second portion is a key-course, and third part is administration and supervision authorities; Described mechanical floor connects key-course through communication cable, and key-course is through wireless network connection management layer.
In the present invention, described mechanical floor comprises the water stop that a plurality of Hardware configuration are identical, and described single water stop comprises a plurality of centrifugal pumps, a frequency converter, a pressure transducer.
In the present invention; Described key-course comprises the main frame that a plurality of Hardware configuration are identical; Described individual host comprises PLC controller, touch-screen, SMS module; The PLC controller connects touch-screen through the RS232 communication link, and the PLC controller connects SMS module through RS485 communication, and the mobile phone card is installed on the SMS module.
In the present invention, described administration and supervision authorities comprise mobile GPRS network and cell phone.
The beneficial effect of the utility model: it is big that the utility model solves traditional network service cost of investment effectively, installs complicatedly, and operation is difficult for, and control singlely, can not carry out controlled whenever and wherever possible and problem that check.
The utility model utilizes China Mobile's GPRS network communication, can cover widely in the whole nation by means of China Mobile's signal, makes remote control technology relatively stable; Its bigger advantage is the restriction that does not receive geographical environment, can cross over mountain after mountain, and need not wiring; Need not manual work and keep an eye on, cost reduces greatly.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model.
As shown in Figure 1, the utility model mainly is made up of three parts, and first is a mechanical floor, and second portion is a key-course, and third part is administration and supervision authorities.Mechanical floor comprises the identical water stop of a plurality of Hardware configuration (always rising to N# water supply pumping plant like 1# water supply pumping plant, 2# water supply pumping plant), and described single water stop comprises a plurality of centrifugal pumps (always rising to centrifugal pump N like centrifugal pump 1), a frequency converter, a pressure transducer.Described key-course comprises the identical main frame of a plurality of Hardware configuration (always rising to main frame N like main frame 1, main frame 2); Gather the data of each corresponding water supply pumping plant that connects by the PLC controller of administration and supervision authorities; Discharge pressure for example, water flow, pump operation state; The pump operation electric current, frequency conversion frequency etc.After carrying out data processing and analyze through the PLC internal controller, divide two paths of signals to transmit, the RS232 of leading up to sends data to touch-screen; Touch-screen figure and luxuriant running status is displayed; Another road sends data to SMS module through RS485, and SMS module carries out will not timing being sent to through China Mobile's GPRS network signal of communication after the data processing and is provided with in the mobile phone, can check each road output current in the mobile phone; Voltage, information such as frequency.Can also write code through mobile phone then information is sent to the scene of water supply, the start and stop of the corresponding centrifugal pump of opertaing device layer.The realization of its work is with the mobile phone card of loading onto a China Mobile on each field erected SMS module that supplies water respectively; Be provided with through program one group of telephone number is provided with into; The user couples together these phone numbers then; Give each on-the-spot cell-phone number through sending fixed code, cell-phone number can be sent to the current device running status on the mobile phone after receiving signal.
More than a kind of wireless remote monitering and control system that is used for tap water supply system that the utility model provided carried out detailed introduction; Principle and embodiment to the utility model among this paper are set forth, and the explanation of above embodiment just is used to help to understand the method and the core concept thereof of the utility model; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
