Description

Technical Field

[0001] This utility model relates to a heating pipeline diagnostic system, a diagnostic terminal, and an operating terminal. Background Technology

[0002] A heating system refers to the general term encompassing boilers in boiler rooms, heat exchange units, outdoor heating pipe networks, and radiators. Heating systems are beginning to shift towards intelligent and low-carbon development.

[0003] In older urban areas, directly buried heating pipes often leak due to corrosion and other reasons, leading to a decline in heating quality during winter. Outdoor heating pipes are buried several meters below the surface, making it difficult to locate leaks visually or by sound in their early stages.

[0004] In existing technologies, leak location through excavation is quite difficult. Leak detection is usually carried out by listening or using robots inside the pipeline. However, both of these methods have drawbacks. The accuracy of leak location by listening is low, and the long pipeline makes the location efficiency low, making it impossible to achieve large-scale real-time monitoring. Locating leaks using robots inside the pipeline has the problem of high usage and maintenance costs. If a large number of robots inside the pipeline are needed to quickly locate a large area of ​​thermal pipelines, a large number of robots are required.

[0005] With the advancement of technology, existing heating and water supply wells are becoming increasingly intelligent (see CN2023200415998 and CN2023100311442), which can solve the problem of underground power supply.

[0006] Existing heating pipeline diagnostic systems are all installed in maintenance wells. Due to power supply limitations, they cannot operate for extended periods and have limited functionality, failing to provide more detailed and accurate heating pipeline inspection data. Utility Model Content

[0036] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0037] Example 1

[0038] See Figures 1 to 4 This embodiment provides a heating pipeline diagnostic system.

[0039] The heating pipeline diagnostic system includes at least one diagnostic terminal 11, at least one accelerometer 12, an operation terminal 13, and an audio playback terminal 14.

[0040] The audio playback terminal is a Bluetooth headset.

[0041] Accelerometers can be two, such as Figure 1 As shown, it can also be one as shown. Figure 5 As shown.

[0042] The acceleration sensor is installed on the heating pipe 15, which includes a water supply pipe and a return pipe. The acceleration sensor transmits vibration signals to the diagnostic terminal.

[0043] The diagnostic terminal 11 includes a communication module 111, a battery module, and a sensor interface. The sensor interface is connected to an accelerometer, and the communication module transmits the vibration signal to the operating terminal.

[0044] The operating terminal transmits vibration sound signals to the audio playback terminal.

[0045] The audio playback terminal outputs the vibration sound signal.

[0046] The diagnostic terminal includes a housing 112, a handle 113 and an antenna 114 on the side of the housing, a charging interface for the battery module, a switch and a sensor interface on the front of the housing, a protective cover on the outside of the antenna, and the communication module connected to the antenna.

[0047] The number of diagnostic terminals is two. The acceleration sensors connected to the two diagnostic terminals are respectively installed on the heating pipes of two adjacent maintenance wells 21. The two diagnostic terminals transmit vibration signals to the same operating terminal through the antenna.

[0048] Using existing programming techniques, the heating pipeline diagnostic system of this embodiment can achieve the following effects:

[0049] Listening Mode: The host terminal selects one of the diagnostic terminal devices for listening. Upon receiving a command from the host, the slave diagnostic terminal activates the headset function on the host terminal interface. The operator then clicks "Listen" to begin the listening test, playing audio through the headset (or speaker) connected to the host. The operator can then perform further analysis based on the listening results or continue to the next listening test. During the listening process, the listening data is stored in the database for data storage and management.

[0050] Data Acquisition Mode: After the host operating terminal and slave diagnostic terminal are powered on, the host selects the listening mode and communicates with the slaves to confirm the current status of each slave. Then, the slave that has successfully communicated is selected for subsequent data acquisition testing. Before the acquisition test, the slaves participating in the acquisition are selected for data collection. The start time for acquisition is then agreed upon. There are two methods for agreeing on the acquisition time: a) One method involves having the slave and host devices together. A countdown time is set, such as 5:00 or 10:00, allowing the slave to count down according to its own clock. During this time, the slave's accelerometer sensor is placed on the pipe, and the slave is placed on the ground, using a horseshoe-shaped magnetic attachment to the pipe to be acquired. When the time reaches 0:00, each slave begins acquiring data and promptly uploads the data, thus achieving data acquisition. b) Another method involves pre-positioning the slave device's sensor on the pipe to be tested, then placing the slave on the ground. Master-slave communication is achieved via Bluetooth or LoRa, and the slave's acquired data is uploaded to the host.

[0051] Data collection enables subsequent diagnostic analysis and data uploading. Other functional modules, such as the homepage, system settings, data transmission, and case analysis, require application analysis based on specific scenarios.

[0052] The communication module is either a LoRa module or a Bluetooth module.

[0053] The operating terminal includes a storage module for storing the vibration signals.

[0054] The operating terminal includes a touch screen display.

[0055] The heating pipeline diagnostic system also includes a pipeline leak detection device 31, which comprises a satellite positioning module 311, a thermoelectric power generation module 312, a battery module 313, and a wireless communication module 314.

[0056] The pipeline leak detection device is connected to two acceleration sensors, which are respectively installed on the water supply pipe and the water return pipe of the heating pipeline. The two acceleration sensors transmit vibration signals to the pipeline leak detection device.

[0057] The thermoelectric power generation module is connected to the battery module and transmits electrical energy to the battery module;

[0058] The battery module is connected to the pipeline leak detection device and transmits electrical energy to the pipeline leak detection device.

[0059] The pipeline leak detection device transmits vibration signals to the operating terminal via a wireless communication module.

[0060] The satellite positioning module sends positioning data to the pipeline leak detection device.

[0061] The acceleration sensor interface of the pipeline leak detection device is the same as the acceleration sensor interface 115 of the diagnostic terminal.

[0062] The pipeline leak detection device is normally placed in the maintenance well. When the data obtained by the pipeline leak detection device is abnormal, the heating pipeline diagnostic system is used for on-site confirmation. The acceleration sensor can be shared, which saves costs.
