Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of community Central heating monitoring system, comprises the PLC module for data processing, is connected the controller being used for field control with PLC module, is connected the host computer being used for Long-distance Control with PLC module; Described PLC module input end be connected with temperature sensor for measuring water temperature, for measure hydraulic pressure pressure transducer, for measuring the water flow sensing unit of flow velocity and the transducer for calculating heat energy loss; Described PLC module output terminal be connected with alarm, GSM message module, for controlling the entering water electromagnetic valve of caliduct water inlet and dropping into the fuel solenoid valve of fuel for controlling boiler.
Wherein, what PLC module adopted is siemens PLC CPU226 type PLC module, S7-200 performance is remarkable, the scope of application can from simple industrial automatic control to the industrial automatic control of complexity, range of application widely, covers all relevant with robotization industry and civil area, comprises various civilian installation, central air conditioner, building automation, package packing machine, engineering machinery, junior machine equipment etc., and cost performance is higher, can meet design requirement.
What field controller adopted is TPC1162Hi type MCGS touch-screen, TPC1162Hi type MCGS touch-screen be the Kunlun, Beijing on-state robotization Science and Technology Ltd. produce towards a touch-screen with industrial automation, it is carry out for MCGS touch-screen a configuration software that configuration uses specially that MCGS embeds version configuration software;
Host computer is personal computer, complete the communication between PLC and computing machine, the computing machine with more than Windows2000 operating system must be used, and MCGS configuration software structure host computer model is installed, adopt PC/PPI cable PLC to be connected line correlation of going forward side by side with computing machine and set.
Temperature sensor adopts PT100 temperature sensor, be arranged on water inlet and the water outlet of Nei Gedong building, community caliduct respectively, gather the temperature feedback of caliduct turnover to PLC, obtain temperature difference, if Inlet and outlet water excessive temperature differentials, then illustrate that water velocity is partially slow, need to control corresponding entering water electromagnetic valve to high tap position work, otherwise then control corresponding entering water electromagnetic valve to low-grade location work; Water flow sensing unit is arranged on the inlet channel in Ge Dong building, records the water velocity of Ge Dong building caliduct; The input end of transducer is connected with the output terminal of temperature sensor and water flow sensing unit respectively, forms a heat energy meter, measures real-time heat loss.
The inlet valve that pressure transducer is arranged on Ge Dong building monitors hydraulic pressure, if caliduct leaks, then hydraulic pressure reduces, host computer correspondence position gives the alarm, prompting staff fixes a breakdown, if the unmanned response of time-out, then PLC transfers GSM message module toward activating alarm note on staff's mobile phone, to ensure that fault obtains the fastest solution.
Because the temperature, pressure, water velocity, the heat energy loss signal that gather in the utility model are analog quantitys, and the central processing unit of PLC can only process digital data, so the sensor will be connected with PLC module by EM231 analog input and output module with transducer, analog quantity is converted into digital quantity; Because solenoid valve feedback information is digital quantity, so can directly be connected with PLC module, be used for monitoring the duty of heating system each solenoid valve.
The I/O of PLC is allocated as follows shown in table:

During work, opening upper computer software can monitor community heating, can show Ge Dong building heating installation water temperature, hydraulic pressure, water velocity, heat energy loss, each caliduct water intaking valve state and heating boiler fuel valve state on computers in real time.
Automatically control if select, system program as shown in Figure 4 carries out work, first water temperature information is gathered, judge that whether temperature is lower than design temperature, then continues monitor water temperature if not, if then postpone again to judge that whether temperature is lower than design temperature after 3 seconds, to prevent from judging mistake, if water temperature is still lower than design temperature, then opens boiler fuel valve and heat, monitor water temperature change simultaneously.When monitor water temperature higher than design temperature after, postpone within 3 seconds, again to judge that whether temperature is higher than design temperature, to prevent from judging mistake, if water temperature is still higher than design temperature, then turn off the fuel door, stop heating.Simultaneously, the temperature difference of system-computed water inlet pipe and rising pipe, if temperature difference exceedes setting range, then illustrate that flow velocity is partially slow, chillout, system continues monitoring after entering water electromagnetic valve being heightened a gear, if temperature difference is lower than setting range, then illustrate that flow velocity is too fast, thermal waste, system continues monitoring after entering water electromagnetic valve being turned down a gear.Transducer, according to water inlet pipe temperature and water velocity, calculates heat energy loss, and the data such as heat energy loss value, conduit temperature, water velocity, hydraulic pressure, each valve state are shown on the remote computer in real time by PLC.
In automatic control process, if break down, then alarm equipment alarm, simultaneous computer shows abort situation and fault type, if the unmanned response of time-out, then PLC transfers GSM message module toward activating alarm note on staff's mobile phone, to ensure that fault obtains the fastest solution.
If selection Non-follow control, then can by the opening and closing of computing machine control Ge Dong building caliduct valve and boiler fuel valve, when valve is extremely closed or opens, the alarm lamp flicker of corresponding valve location on computing machine, alarm rings prompting staff handling failure simultaneously.The caliduct in Mei Dong building is all provided with independent touch screen controller, and touch screen controller is arranged in control box, and staff also directly can be controlled community Central heating monitoring system by touch screen controller at the scene.
