A kind of implementation method for heat death theory and the fast-selling control system sold, the implementation method include the following steps：
Mobile heat supply vehicle takes prepayment IC-card to buy hot mode, that is, moves heat supply vehicle driver hall of going to pay dues and need to buy according to it
Heat carry out pre-paying, staff's amount of money that can will be paid dues by the dedicated prepayment IC-card management software of this system is charged to IC
In card；
IC card is inserted into front-end control box by purchase heat side, and the hot water amount for wanting purchase is set on the touch screen of control cabinet；
Heat death theory control cabinet deducts the purchase corresponding amount of money of hot water amount out of card, while controlling motor-driven valve and putting hot water.
Further, the implementation method for heat death theory and the fast-selling control system sold includes prepayment IC-card management
Method, prepayment IC-card management method include the following steps：
Step S101 is logged in, and user distinguishes behaviour in the login interface of control software by inputting different account name and password
Make grade, user operates according to the permission authorized, and realizes differentiated control, enters step S102 and step S103 after the completion；
Step S102 carries out system setting, hair fastener company, client company, measurement unit, unit price etc. can be arranged according to actual conditions
Parameter；
Step S103, inquiry, can inquire IC card and supplement the reports such as record, usage record with money.
Further, the prepayment IC-card management method is further comprising the steps of：
IC card is placed into card reader and is identified by step S104, Card Reader, the IC card ability only Jing Guo control system mandate
It identifies successfully, otherwise IC card None- identified, enters step S105, step S106, step S107 after the completion；
Step S105 mends card, when user loses card, blank card can be read, then searching user's information, and write information into
Neocaine enters step S108 after the completion；
Step S106, hair fastener read blank card, and by user's name, card number, contact person, the write-ins card such as address information, just
Just it inquires and operates in the future, enter step S108 after the completion；
Step S107, cancellation eliminate the card image of client to the timely cancellation of the card of loss.
Further, the prepayment IC-card management method is further comprising the steps of：
Step S108, is supplemented with money, after hair fastener and benefit card, should be supplemented with money to card according to actual conditions, user-friendly, is completed
After enter step S109；
Step S109, card taking after end of operation, fetch card, can arrive heat death theory at any time and fast sale sells control cabinet and carries out plug-in card and disappears
Take.
Further, the implementation method for heat death theory and the fast-selling control system sold further includes heat death theory and fast sale
Control cabinet management method is sold, the heat death theory and fast sale are sold control cabinet management method and included the following steps：
Step S201, initialization system parameter, setting room temperature, hot water temperature's alarming value, amount of money coefficient, lead, offset, flow
The parameters such as the upper limit, flux lower limit, temperature upper limit, lowest temperature, enter step S202 after the completion；
Step S202, water temperature judgement, set water temperature are entered step when actual water temperature is less than setting hot water temperature's alarming value
S203 enters step S204 if water temperature is normal；
Water, and alert are sold in step S203, stopping；
Step S204, Card Reader read the card image of prepayment IC-card, and the information of reading is displayed on control cabinet man-machine interface
On, including customer name, remaining sum etc., and these information can be recorded in real time, facilitate the later stage to inquire.
Further, it is further comprising the steps of to sell control cabinet management method for the heat death theory and fast sale：
Step S205, setting purchase water information, sets purchase water, enters step S206 after the completion；
Step S206, remaining sum judgement, if setting purchase water enters step S207, remaining sum abundance then enters beyond remaining sum in card
Step S208；
Step S207, Sorry, your ticket has not enough value alarm, balance amount prompting deficiency, and release card；
Step S208, hot water amount's judgement, if setting purchase water enters step S209, if hot beyond surplus water in water tank
Water is sufficient, then enters step S210；
Step S209, water amount alarm prompt water shortage, and return to step S205 is needed to reset purchase water；
Step S210, amount deducted deduct the amount of money corresponding to purchase water from IC card.
Further, it is further comprising the steps of to sell control cabinet management method for the heat death theory and fast sale：
Step S211, valve opening discharge water, and PLC controls motor-driven valve and opens, and discharge hot water, if drainage procedure midway manual termination reaches water,
S212 is then entered step, if reaching intended procurement water, enters step S213；
Step S212, motor-driven valve are closed, and the amount of money of remaining purchase water is refilled in card again, are entered step after the completion
S213；
Step S213, PLC control motor-driven valve is closed, and enters step S2014 after the completion；
Step S214, receipt can be printed as needed in man-machine interface, enter step after the completion after valve is closed by printing receipt
S215；
Step S215 clicks " moving back card ", card then automatic spring in man-machine interface.
Further, step S207, Sorry, your ticket has not enough value alarm, balance amount prompting deficiency, and release card；
When Sorry, your ticket has not enough value in card, client is reminded to change setting value or supplement with money in time；
It sells in thermal process, when remaining sum is relatively low in card, motor-driven valve is gradually reversely closed, and when card remaining sum is zero, motor-driven valve is whole
It closes, heat is sold in stopping.
Further, motor-driven valve closing includes following two situations in the step S213：
When soon reaching the tonnage of setting purchase, electrically operated valve is reversed in advance to close, and lead can be set in touch screen picture
It sets, is adjusted at any time according to on-site actual situations；
When reaching the purchase water tonnage of setting, electrically operated valve completely closes, and in order to realize that metering is accurate, heat death theory control cabinet is automatic
The difference for actually selling heat and setting value is corrected, and this difference is adapted in the remaining sum of prepaid card.
The present invention is had the following technical effect that compared with prior art using above technical scheme：
Heat can be accurately measured, and is sold by way of swiping the card, every control cabinet can work independently, can be with
Printing simply sells bill, and can form detailed sales figure, inquires and refers to for staff.

9. a kind of implementation method for heat death theory and the fast-selling control system sold as claimed in claim 7, it is characterised in that：
Step S207, Sorry, your ticket has not enough value alarm, balance amount prompting deficiency, and release card；
When Sorry, your ticket has not enough value in card, client is reminded to change setting value or supplement with money in time；
It sells in thermal process, when remaining sum is relatively low in card, motor-driven valve is gradually reversely closed, and when card remaining sum is zero, motor-driven valve is whole
It closes, heat is sold in stopping.
10. a kind of implementation method for heat death theory and the fast-selling control system sold as claimed in claim 8, feature exist
In：Motor-driven valve closing includes following two situations in the step S213：
When soon reaching the tonnage of setting purchase, electrically operated valve is reversed in advance to close, and lead can be set in touch screen picture
It sets, is adjusted at any time according to on-site actual situations；
When reaching the purchase water tonnage of setting, electrically operated valve completely closes, and in order to realize that metering is accurate, heat death theory control cabinet is automatic
The difference for actually selling heat and setting value is corrected, and this difference is adapted in the remaining sum of prepaid card.
