Description

Technical Field

[0001] The invention relates to the technical field of heating fault repair, and in particular to a heating fault rapid repair method based on a HVAC heating project. Background Art

[0002] The urban heating system is an important infrastructure in northern China. The system is large and complex, including: energy station, primary pipe network heat exchange station, secondary network heat exchange station and other multi-level systems. The system is equipped with independent primary heating circulation network and secondary heating circulation network, using air source heat pump or gas boiler unit as a stable heating source. The primary network supplies heat to the secondary network through the thermal heat exchange station, and the secondary network transfers the heat to the user. In the prior art, since the secondary network is a user-side pipeline, the number is large and the distribution is dense, the traditional manual regular fault detection of the heating pipeline in the secondary network can no longer meet the needs of modern secondary network fault detection. Summary of the invention

[0003] The present invention provides a rapid maintenance method for heating failures based on HVAC and heating engineering to solve the problems raised in the above background technology.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A rapid maintenance method for heating failure based on HVAC heating engineering, comprising the following steps:

[0006] The first step is to install a data acquisition module in each heating water pipe;

[0007] In the second step, each data acquisition module can remotely send the relevant data of the heating water pipe to the remote monitoring server through the wireless transmission module;

[0008] In the third step, the remote monitoring server is used to analyze whether there is a fault in the heating water pipe through the relevant data of the heating water pipe.

[0009] As a further improvement of the present technical solution: the data acquisition module includes a water flow velocity sensor and a locator, and each heating water pipe is installed with a water flow velocity sensor and a locator.

[0010] As a further improvement of the technical solution: the remote monitoring server is also used to control the power of the water delivery pump of the heating water pipe.

[0011] As a further improvement of the technical solution: the remote monitoring server includes an abnormal data monitoring unit, an anti-false alarm verification unit, and a normal water supply data storage unit;

[0012] The normal water supply data storage unit is used to store the normal water flow speed in all heating water pipes at different powers of the heating water pipe water delivery pump;

[0013] The abnormal data monitoring unit is used to monitor whether the heating water pipe has leakage;

[0014] The anti-false alarm verification unit is used to verify whether all heating water pipes are leaking.

[0015] As a further improvement of the present technical solution: the abnormal data monitoring unit is used to monitor whether the heating water pipe is leaking. Specifically, the abnormal data monitoring unit monitors the water flow velocity in the heating water pipe through a water flow velocity sensor, and compares the received water flow velocity value with the normal water flow velocity value in the heating water pipe under the same heating water pipe water pump power in the normal water supply data storage unit. If the difference exceeds 10%, it is preliminarily determined that the heating water pipe is leaking.

[0016] As a further improvement of the present technical solution: the anti-false alarm verification unit is used to verify whether the heating water pipe has leaked. Specifically: when the abnormal data monitoring unit preliminarily determines that the heating water pipe has leaked, the anti-false alarm verification unit can change the power of the heating water pipe water pump, and then compare the water flow velocity value received at this time with the normal water flow velocity value in the heating water pipe under the same heating water pipe water pump power. If the difference still exceeds 10%, it is finally determined that the heating water pipe has leaked.

[0017] As a further improvement of the present technical solution: the wireless transmission module is any one of a 5G communication module, a 4G communication module, a Bluetooth module, a WiFi module, a GSM module, a CDMA module, a CDMA2000 module, a WCDMA module, a TD-SCDMA module, a Zigbee module and a LoRa module, or a combination of any several of them.

[0018] As a further improvement of the technical solution: the locator is a GPS positioning terminal or a Beidou positioning terminal.

[0019] As a further improvement of the technical solution: it also includes that the remote monitoring server can send the location where the leakage failure of the heating water pipe is finally determined to be occurring to the terminal of the maintenance personnel, so as to remind the maintenance personnel to carry out timely maintenance.

[0020] As a further improvement of the technical solution: after the maintenance personnel complete the maintenance, they need to provide timely feedback to the remote monitoring server.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention has a reasonable design and ingenious conception, and can solve the inconvenience of traditional urban heating system monitoring. It also greatly reduces the false alarm situation through the anti-false alarm verification unit, and can efficiently collect operating status data in real time for real-time monitoring, thereby improving the effectiveness and reliability of heating water pipe monitoring.

[0030] See also Figure 1 In an embodiment of the present invention, a rapid maintenance method for heating failure based on a heating and ventilation engineering project includes the following steps:

[0031] The first step is to install a data acquisition module in each heating water pipe. The data acquisition module includes a water flow velocity sensor and a locator. Each heating water pipe is installed with a water flow velocity sensor and a locator. Among them, the wireless transmission module is any one or a combination of 5G communication module, 4G communication module, Bluetooth module, WiFi module, GSM module, CDMA module, CDMA2000 module, WCDMA module, TD-SCDMA module, Zigbee module and LoRa module, and the locator is a GPS positioning terminal or a Beidou positioning terminal.

[0032] In the second step, each data acquisition module can remotely send the relevant data of the heating water pipe to the remote monitoring server through the wireless transmission module. The remote monitoring server is also used to control the power of the water delivery pump of the heating water pipe;

[0033] The third step is to use the remote monitoring server to analyze whether there is a fault in the heating water pipe through the relevant data of the heating water pipe. The remote monitoring server includes an abnormal data monitoring unit, an anti-false alarm verification unit, and a normal water supply data storage unit;

[0034] The normal water supply data storage unit is used to store the normal water flow speed in all heating water pipes at different powers of the heating water pipe water delivery pump;

[0035] The abnormal data monitoring unit is used to monitor whether the heating water pipe is leaking. Specifically, the abnormal data monitoring unit monitors the water flow velocity in the heating water pipe through a water flow velocity sensor, and compares the received water flow velocity value with the normal water flow velocity value in the heating water pipe under the same heating water pipe water pump power in the normal water supply data storage unit. If the difference exceeds 10%, it is preliminarily determined that the heating water pipe is leaking.

[0036] The anti-false alarm verification unit is used to verify whether the heating water pipe has leaked. Specifically, when the abnormal data monitoring unit initially determines that the heating water pipe has leaked, the anti-false alarm verification unit can change the power of the heating water pipe water pump, and then compare the water flow velocity value received at this time with the normal water flow velocity value in the heating water pipe under the same heating water pipe water pump power. If the difference is still more than 10%, it is finally determined that the heating water pipe has leaked.

[0037] In the fourth step, the remote monitoring server can send the final location of the heating water pipe leakage fault to the maintenance personnel's terminal to remind the maintenance personnel to carry out timely maintenance. After the maintenance is completed, the maintenance personnel need to provide timely feedback to the remote monitoring server.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
