For example, patent documents with patent grant publication numbers CN213393931 and IPC classification number F16L9/14 disclose a multilayer prefabricated insulating pipe with low thermal conductivity, and the purpose of reducing energy loss is achieved mainly by improving the thermal conductivity of the insulating pipe as can be seen from the insulating pipe structure.

The internet of things cloud database is used for storing all threshold parameters and all design parameter information related to the target multichannel management system and extracting all units from the cloud.

In any of the above aspects, it is preferable that the parameters related to the heat source water in the internal conveyance state of the target multichannel piping in the multichannel piping built-in heat source water parameter obtaining unit include: the conductivity of heat source water in the pipeline, the temperature of heat source water entering the pipeline at the starting end of the multi-channel pipeline system, the temperature of heat source water exiting the pipeline at the tail end of the multi-channel pipeline system, the effective length of an underground embedded pipeline and the effective length of an overhead pipeline in the whole multi-channel pipeline system.

Before parameter acquisition, pre-installing corresponding sensor elements and configuring corresponding solar cells for pipeline sampling points according to conventional means, wherein during construction, matching installation is completed by conventional installers in the field; the design parameters related to the original multi-path pipe system are stored in the Internet of things cloud database in advance, so that the follow-up extraction and use at any time are facilitated.

In any of the above schemes, preferably, the specific working process of the multi-path pipe system built-in heat source water parameter obtaining unit is as follows:

acquiring conductivity of heat source water inside a pipeline at each stage in a flowing stateWherein->Indicating the current firstA number of individual conductivities;

Using the formulaObtaining a water quality change coefficient in a pipeline of the multi-channel pipeline system;

it should be noted that, the water quality change coefficient can reflect the current resistance change condition of the heat source water in the pipeline by obtaining the change of the conductivity, and reflect the quality condition of the water quality at the same time, when the conductivity of the heat source water in the pipeline is along with that of the heat source water in the pipelineThe water quality is continuously deteriorated when the water quality is increased, which indicates that the internal impurities are increased, thereby reflecting the corresponding pipelines of the current multi-channel pipeline systemThe filtering system has hidden trouble, rust impurities and scale impurities affect the water quality, so that the health state of the pipeline can be effectively reacted.

When the heat source is in hydro-thermal delivery temperature loss deviation degreeWhen the water temperature is smaller than the set threshold value, the current heat source hydrothermal conveying heat preservation loss meets the requirement; otherwise, when the current heat source hydrothermal transportation heat preservation loss has excessive loss, an abnormal early warning signal is sent.

In the actual operation process of the hot water source in the relation pipeline, the conventional coefficients are obtained by acquiring the design parameter information of the pipeline in advance, meanwhile, the proper weight ratio is selected according to the common sense of industry in consideration of the difference of the influence weights of the underground embedded pipeline and the overhead pipeline, the current heat source hydrothermal conveying temperature loss deviation degree can be obtained after the heat preservation loss calculation formula and the pipeline heat preservation loss theoretical value obtained through conventional calculation or theory are compared, so that the problem that whether the heat source hydrothermal conveying temperature loss deviation degree of the current pipeline has excessive deviation in the operation process is accurately reflected, whether the operation state of the current pipeline reaches the standard is rapidly reflected, and judgment can be rapidly obtained according to the calculation result.

The calculation of the water flow change rate of the internal heat source water is realized through a multipoint monitoring and analyzing mode, and when leakage occurs in the flange connection part, the phenomenon of vortex or turbulence is caused, so that the current water flow speed of the leakage point position can change in direction and speed, and the supervision of the water flow speed of the leakage point position can be effectively ensured by controlling the supervision of the water flow speed of the leakage point position.

By analysis of formulasObtaining the abnormal risk coefficient of the flange connection of the current same flange connection part >。

It should be noted that, considering that the mechanical influence factor of leakage at the leakage position is caused by loosening of the connecting piece at the current flange connection position, the supervision of the nut washers at each flange connection position can be controlled to timely control the nut washer condition at the flange connection position when the leakage trend occurs, and the double-effect supervision is effectively matched with the change of the flow velocity of the heat source water, so that the occurrence of the condition that the leakage cannot be predicted or found due to small-range cavitation is avoided, the influence of the factors of the nut washer vibration caused by the flow velocity change of the heat source water matched with the leakage water flow impact, the influence of the factors of the nut washer vibration caused by the pressure, the water flow impact force and the like is avoided, and the supervision accuracy is improved.
