Detection and control terminal 4 has adopted the GT50 detection and control terminal of Tianjin Development Co., Ltd of blue Shenzhen Science and Technology, this detection and control terminal is the industrial computer that directly applies to industry spot, it is the integration apparatus that comprises multiple template, the storage user's heat condition monitoring program same with the central computer control module in the machine, the various data of parameter such as the scaled value of the high limit of the corresponding heat supply flow of respective settings and lower bound and computational process, its function is directly to handle the flow signal of flowmeter 8, gather the instantaneous heat supply flow of user's feed pipe by flowmeter, when uploading, data on flows carries out this locality conversion and calculating, and by comparing with setting ceiling value and low limit value, the opening and closing of gauge tap control valve, realize local closed-loop control, while can be with instantaneous heat supply flow signal under the telecommunication normal condition, local overload alarm signal passes through concentrator, the GPRS communicator is uploaded to the central computer control module 1 of heating network administrative center.
The function of GPRS communicator is to realize the communication system of the data communication of detection and control terminal and central computer control module, adopt the communication modes of the conventional APN VPN that uses at present, selected the GPRS communicator of Tianjin Development Co., Ltd of blue Shenzhen Science and Technology in this example for use.
The function of concentrator is all users in the building to be concentrated with the signal of the detection and control terminal of thermal control units unusually upload.In this example, concentrator has adopted the concentrator of Qinhuangdao flourish wound development in science and technology Co., Ltd.
Below for adopting above-mentioned central heating pipe network user's heat abnormality monitoring system to carry out the method for user's heat abnormality monitoring, referring to Fig. 2.
The step of this method is as follows:
⑴ system brings into operation, and detection and control terminal 4 is gathered data and the execution in step ⑵ of instantaneous heat supply flow F; Inquire simultaneously whether telecommunication normal, when telecommunication just often, give central computer control module 1 with above-mentioned data upload, and execution in step ⑶, when telecommunication was interrupted, these data were overflowed, and continued maintenance inquiry state;
⑵ detection and control terminal 4 is converted into instantaneous velocity V with instantaneous heat supply flow F, and compares with the instantaneous velocity ceiling value V1 that sets and the low limit value V2 of instantaneous velocity, judges the user's heat state:
(2.1) as instantaneous velocity value V during greater than instantaneous velocity ceiling value V1, this moment, explanation may be that pipeline leakage accident or the indoor water privately of user have taken place, and must close switching control pilot 7, EP (end of program); Produce local superelevation limit alarm signal simultaneously and inquire whether telecommunication normal, when telecommunication just often, upload local superelevation limit alarm signal to the central computer control module, this moment execution in step ⑷; When telecommunication was interrupted, described local superelevation limit alarm signal data were overflowed, and continue to keep the inquiry state;
(2.2) as instantaneous velocity value V during smaller or equal to instantaneous velocity ceiling value V1, judge that further instantaneous velocity value V is whether less than the low limit value V2 of instantaneous velocity:
(2.2.1) when instantaneous velocity value V hangs down limit value V2 less than instantaneous velocity, this moment explanation may be that the heating user pipeline blockage or user have been taken place is drawn privately in the outdoor side of gauge table and connects water or the people is the valve of having closed on the indoor heating facility, produce local ultralow limit alarm signal and inquire whether telecommunication is normal this moment, when telecommunication just often, upload local ultralow limit alarm signal to the central computer control module, at this moment execution in step ⑸; When telecommunication was interrupted, above-mentioned this locality ultralow limit alarm signal data were overflowed, and continued to keep the inquiry state;
(2.2.2) when instantaneous velocity value V hangs down limit value V2 more than or equal to instantaneous velocity, illustrate that user's heat is normal, continue circulation;
⑶. the central computer control module receives the instantaneous heat supply flow F that detection and control terminal uploads and calculates and judge the hot state of using:
(3.1) instantaneous heat supply flow F is converted into instantaneous velocity V, and compares with the instantaneous velocity ceiling value V1 that sets and the low limit value V2 of instantaneous velocity, judge the user's heat state:
(3.1.1) whether judge instantaneous velocity value V greater than instantaneous velocity ceiling value V1, if instantaneous velocity value V, then sends long-range superelevation limit sound and light alarm signal greater than instantaneous velocity ceiling value V1, this moment, administrative center notified personnel on site fault clearing; Equal instantaneous velocity ceiling value V1 and then carry out following steps:
(3.1.2) whether judge instantaneous velocity value V less than the low limit value V2 of instantaneous velocity, if instantaneous velocity value V then sends long-range ultralow limit sound and light alarm signal less than the low limit value V2 of instantaneous velocity, this moment, administrative center notified personnel on site fault clearing; If instantaneous velocity value V illustrates that more than or equal to the low limit value V2 of instantaneous velocity user's heat is normal;
⑷ send local superelevation limit sound and light alarm signal when local superelevation limit alarm signal that central computer control unit 1 receives that detection and control terminal 4 uploads, at this moment, administrative center notifies personnel on site fault clearing;
⑸ send local ultralow limit sound and light alarm signal when local ultralow limit alarm signal that central computer control unit receives that detection and control terminal 4 uploads, at this moment, administrative center notifies personnel on site fault clearing.
Above-mentioned instantaneous velocity ceiling value V1=1.5-2m/s, instantaneous velocity hangs down limit value V2=0.1-0.3m/s.
In sum, the central heating pipe network user's heat abnormality monitoring system and the above-mentioned method for supervising that have adopted the utility model to provide, realized the user's heat abnormality reliable, judge also timely and can in time solve, when instantaneous heat supply flow increases and surpasses that to set ceiling value then may be that leakage accident or the indoor water privately of user have taken place, this moment can be by this locality control emergency cut-off switching control pilot 7 of detection and control terminal 4, and by uploading local alarm signal, send the related personnel to enter the scene by administrative center and carry out actual checking, fix a breakdown, eliminate the heat anomaly state of using.When instantaneous heat supply flow reduces and surpasses the determinated low limit value, then may be that pipeline blockage has taken place the user, or the user draws privately in the outdoor side of gauge table and connects water or the people is the valve of having closed on the indoor heating facility, this moment is by uploading local alarm signal, send the related personnel to enter the scene by administrative center and carry out actual checking, solve and eliminate and use hot state unusually.Simultaneously, the instantaneous heat supply data on flows of central computer control module by accepting calculated simultaneously, judged and the hot state of unusual usefulness is sent remote alarms, and gets rid of field failure.Guarantee the normal stable heating of heating system thus, prevent the wasting of resources, improve the security of heating system, improve comfortableness and the security of user's heat.
