The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Example one
Fig. 1 is a schematic circuit connection diagram of a device for detecting leakage of a thermal pipeline according to an embodiment of the present invention. Referring to fig. 1, the apparatus for detecting leakage in a thermal pipe includes: the temperature sensor is buried along the thermal pipeline and used for collecting the soil temperature along the thermal pipeline; and the data transmission unit is electrically connected with the temperature sensor and is used for receiving the temperature data from the temperature sensor and sending the temperature data.
Illustratively, the temperature sensor can collect ambient temperature, and in this embodiment, the temperature sensor can be buried in the ground at a depth of 1-2 m and along the thermal pipeline as close as possible to the thermal pipeline. The temperature of the soil in the ambient environment adjacent the thermal pipeline may be collected. When a thermal pipeline is normal, the temperature of the soil around the thermal pipeline is usually within a certain temperature variation range. When the heat pipeline leaks, the temperature of the soil around the heat pipeline is increased sharply due to the hot water in the heat pipeline leaking into the soil. Therefore, whether the thermal pipeline leaks at the position where the temperature sensor is embedded can be judged according to the temperature of the soil of the surrounding environment near the thermal pipeline, which is acquired by the temperature sensor.
Because temperature sensor need bury underground, can't audio-visual obtain the temperature that temperature sensor gathered, consequently, in this embodiment, the detection device that heating power pipeline leaked still includes: and the data transmission unit is electrically connected with the temperature sensor and is used for receiving the temperature data from the temperature sensor and sending the temperature data.
Specifically, the data transmission unit may send the temperature data received from the temperature sensor to a remote server by using an existing mobile communication network, so that a user may check the temperature of soil near the thermal pipeline along which the detection device for detecting the leakage of the thermal pipeline is located through the remote server, and may determine whether the thermal pipeline is leaked at a change point through the temperature change of the soil.
Optionally, in this embodiment, the temperature sensor may be a Si7021 temperature and humidity sensor, and the Si7021 is a temperature and humidity sensor chip produced by Silicon Labs, and integrates a humidity and temperature sensor element, an analog-to-digital converter, signal processing, calibration data, and an I2C host interface. The method has the advantages of high precision, low power consumption, long-term stability and the like. The data transmission unit can adopt a BC95 chip, and BC95 is an NB-IoT wireless communication module with high performance and low power consumption. The requirement of terminal equipment on small-size module products can be met to the maximum extent. The BC95 is compatible with the M95 module of GSM/GPRS series in design, thereby facilitating the quick and flexible product design and upgrade of customers. The BC95 has high reliability due to the SMT patch technology, so that the application requirements under complex environments can be met. The ultra-low power consumption wireless sensor network has the advantages of compact size, ultra-low power consumption, ultra-wide working temperature range and the like, has stronger penetrability by adopting the NB-IoT technology, and can normally transmit and receive signals within the underground range of 1-2 meters. The method is particularly suitable for detecting the leakage condition of the heat distribution pipeline.
In this embodiment, an SDA pin of the Si7021 temperature and humidity sensor is electrically connected to an SWD _ DATA pin of the BC95 chip; and an SCL pin of the Si7021 temperature and humidity sensor is electrically connected with an SWD _ CLK pin of the BC95 chip. Wherein the SDA is used for transmitting temperature data and the SCL is used for sending clock signals. The reason why the above connection mode is adopted is that the Si7021 temperature and humidity sensor and the BC95 chip are both I2C bus devices, and on one hand, a clock signal is transmitted through an SCL output circuit, and on the other hand, the SCL level on the bus is detected to determine when to transmit the next clock pulse level.
Preferably, the device for detecting leakage of the heat distribution pipeline only adopts a heat distribution pipeline which is buried at the position along the line of the heat distribution pipeline which is easy to leak, so as to monitor whether the leakage occurs at the point. As a preferred embodiment, a plurality of thermal pipeline leakage detection devices can be embedded along the thermal pipeline at preset intervals. To enable leak detection along the entire thermal conduit.
The detection device for detecting leakage of the heat distribution pipeline provided by the embodiment can effectively measure temperature change of the heat distribution pipeline by using the temperature sensor embedded along the heat distribution pipeline, and can send the temperature to the remote server through the data transmission unit, so that a user can determine whether leakage occurs at the position where the current temperature sensor is located according to the temperature data received by the server. Compared with the traditional mode, the large-scale geotechnical work is not needed, meanwhile, the subsection is not needed to be pressed and the human eye observation is not needed, the detection workload is reduced, and compared with the subsection pressing and the human eye observation, the two modes for determining the leakage point are more direct and accurate.

And 3 capture \ compare register units are available for comparing the magnitude of the values. Therefore, the NRF53832 chip can obtain the current temperature from the Si7021 temperature and humidity sensor, store the obtained temperature value in the capture \ comparison register unit to be compared with the preset temperature value, transmit the obtained temperature value into the BC95 chip when the temperature exceeds the preset temperature, and transmit the temperature exceeding the preset temperature to the remote server through the BC95 chip. Specifically, a P0.02 pin of the NRF53832 chip is electrically connected with an SDA pin of the Si7021 temperature and humidity sensor, and a P0.03 pin of the NRF53832 chip is electrically connected with an SCL pin of the Si7021 temperature and humidity sensor; the NRF rx pin of the NRF53832 chip is electrically connected with the main tx pin of the BC95 chip, and the NRF tx pin of the NRF53832 chip is electrically connected with the main rx pin of the BC95 chip. The P0.02 pin of the NRF53832 chip is a GPIO port, the P0.02 pin of the NRF53832 chip is a clock synchronization port, and data transmission between the NRF53832 chip and the Si7021 temperature and humidity sensor in an I2C bus mode and data transmission between the NRF53832 chip and the BC95 chip in a serial port mode can be realized through the connection mode.
Since the NRF53832 chip can realize the function of storing and comparing data of detection device values of temperature heat distribution pipeline leakage, the data collected by the Si7021 temperature and humidity sensor at regular time can be pre-stored and screened by adding the NRF53832 chip, and the suspected leakage temperature data can be sent to a remote server through the BC95 chip. The temperature data volume that the staff looked over is reduced, the accuracy that thermal power pipeline leak testing can further be improved. Meanwhile, the data volume sent is reduced, so that the power consumption of the detection device for detecting the leakage of the thermal pipeline can be further reduced, and the service life of the detection device for detecting the leakage of the thermal pipeline are prolonged.
