[0002] Ports are key energy transportation enterprises, which can transport energy such as coal. When storing energy such as coal in transit, the temperature monitoring of coal piles is an important measure to ensure the safe storage of coal and prevent spontaneous combustion. Traditional temperature monitoring means include manual inspection, using wired sensor networks, etc. Since port yards are usually vast in area, coal piles are large in volume and unevenly distributed, manual inspection is inefficient and it is difficult to ensure the accuracy and timeliness of real-time monitoring; while wired sensor networks require a large number of cables and wiring work, which not only increases the initial investment cost, but also increases the difficulty and cost of later maintenance, and there are problems such as complex wiring, high cost, and difficult maintenance. In addition, the wired monitoring system is limited by the cable length and layout, and it is difficult to achieve full coverage and real-time monitoring of the temperature of all corners of the coal pile, resulting in the existence of monitoring blind spots and the inability to comprehensively grasp the temperature status of the coal pile. When expanding new monitoring points, re-wiring is required, with poor flexibility and inconvenience for quick adjustment according to coal pile changes or new demands.

[0003] Through the above analysis, the problems and defects existing in the prior art are: the temperature monitoring method for traditional port yard coal piles has limited monitoring range, high cost, difficult maintenance, poor real-time performance, and poor scalability. Summary of the Utility Model

[0004] To overcome the problems existing in the related art, the utility model provides a real-time monitoring device for the temperature of coal piles in port yards.

[0005] The technical solution of the utility model is as follows: A real-time monitoring device for the temperature of coal piles in port yards is provided with a plurality of temperature sensors arranged at different positions of the coal pile. The outer end of the temperature sensor is connected with a LoRa wireless signal transmitter. The LoRa wireless signal transmitter is connected with a data transfer station through a wireless signal. The data transfer station is connected with a host computer through the Internet. The host computer is connected with an audible and visual alarm through a connection line;

[0006] The data transfer station includes a housing. A wireless signal receiver and a data processor are fixed inside the housing. A wireless / wired communication interface and a power supply interface are embedded on the outside of the housing. The wireless / wired communication interface and the power supply interface are respectively connected with the data processor through connection lines.

[0007] In one embodiment, the temperature sensor adopts an NTC thermistor plug-in thermometer, and a connection belt is used for series connection between a plurality of temperature sensors.

[0008] In one embodiment, fixed collars are connected at equal intervals in the middle of the connecting belt, and the temperature measuring rod of the NTC thermistor plug-in temperature measuring instrument passes through the middle of the fixed collars.

[0009] In one embodiment, a backup power supply is fixed inside the housing, and the backup power supply is connected to the power supply interface and the data processor respectively through connection lines.

[0010] In one embodiment, a storage hard disk is fixed inside the housing, and the storage hard disk is connected to the data processor through a connection line.

[0011] In one embodiment, the upper computer is connected to a remote mobile terminal through a wireless signal.

[0012] Combined with the above technical solutions, the beneficial effects of the present utility model are as follows: Through the temperature sensors arranged at different positions of the coal pile and combined with the LoRa wireless signal transmission technology, the present utility model realizes the full coverage and real-time monitoring of the coal pile temperature, eliminates the monitoring blind spots existing in the traditional wired monitoring system, and ensures the comprehensive and accurate monitoring of the coal pile temperature. The wireless transmission method eliminates a large number of cables and wiring work, significantly reducing the initial investment cost and the later maintenance cost of the system. At the same time, the flexibility and scalability of the wireless system also make maintenance and upgrade simpler and more convenient. By connecting to the upper computer, the temperature data can be transmitted to the remote monitoring center in real time, and the management personnel can centrally manage and analyze the temperature data through the upper computer, realizing the intelligent management of the coal pile temperature, which helps to improve the management efficiency and reduce the errors and omissions caused by human factors. The real-time monitoring and timely alarm functions help to prevent safety accidents such as spontaneous combustion of the coal pile, thus ensuring the safe production of the port yard. At the same time, the intelligent management also improves the emergency response speed, reduces the accident losses, and enhances the safety performance.

[0013] The monitoring system of the present utility model based on the LoRa wireless signal transmission technology has good scalability. When new monitoring points need to be added, only temperature sensors and LoRa wireless signal transmitters need to be installed at the corresponding positions, and the system can be easily expanded, providing convenience for users to flexibly adjust according to actual needs.

Specific embodiments

[0020] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0021] As Figure 1 As shown, the real-time coal pile temperature monitoring device provided by an embodiment of the present utility model includes a plurality of temperature sensors 1 arranged at different positions of the coal pile. The outer end of the temperature sensor 1 is connected to a LoRa wireless signal transmitter 2. The LoRa wireless signal transmitter 2 is wirelessly connected to a data transfer station 3. The data transfer station 3 is connected to a host computer 4 through the Internet. The host computer 4 is connected to an audible and visual alarm 5 through a connection line.

[0022] Preferably, the temperature sensor 1 in the embodiment of the present utility model adopts an NTC thermistor insertion type temperature measuring instrument. A plurality of temperature sensors 1 are connected in series by a connecting belt 12. Connecting a plurality of temperature sensors 1 in series through the connecting belt 12 simplifies the installation process and reduces the installation cost. At the same time, the connecting belt 12 facilitates the search for the position of the temperature sensor 1 and also facilitates subsequent maintenance and replacement work, improving the maintainability of the system.

[0023] Preferably, the host computer 4 in the embodiment of the present utility model is connected to a remote mobile terminal through a wireless signal. The host computer 4 can use the wireless signal to transmit monitoring information and alarm signals to the remote mobile terminal, improving the information sharing range.

[0024] As shown Figure 2 in FIG. 3, the data transfer station 3 in the embodiment of the utility model includes a housing 6, a wireless signal receiver 9 and a data processor 10 are fixed inside the housing 6, a wireless / wired communication interface 7 and a power supply interface 8 are embedded on the outer side of the housing 6, and the wireless / wired communication interface 7 and the power supply interface 8 are respectively connected to the data processor 10 through connection lines.

[0025] Preferably, a backup power supply 11 is fixed inside the housing 6 in the embodiment of the utility model, and the backup power supply 11 is respectively connected to the power supply interface 8 and the data processor 10 through connection lines. The backup power supply 11 can be used for emergency when the external circuit is powered off, ensuring the stable operation of the monitoring device.

[0026] Preferably, a storage hard disk 14 is fixed inside the housing 6 in the embodiment of the utility model, and the storage hard disk 14 is connected to the data processor 10 through a connection line. The monitoring data can be locally cached through the storage hard disk 14, ensuring the security of the detection data.

[0027] As shown Figure 3 in FIG. 4, fixing collars 13 are connected at equal intervals in the middle of the connecting belt 12 in the embodiment of the utility model, and the temperature measuring rod of the NTC thermistor plug-in type temperature measuring instrument passes through the middle of the fixing collars 13. The fixing collars 13 can facilitate the installation and position limitation of the temperature sensor 1, so that when the connecting belt 12 is pulled, the two temperature sensors 1 at adjacent positions can be quickly found, avoiding the loss of the temperature sensor 1 covered by the coal pile.

[0028] The working principle of the utility model is as follows: when the utility model is in use, the temperature data inside the coal pile is collected in real time by the temperature sensors 1 distributed at different positions of the coal pile, and the data is transmitted to the data transfer station 3 by the LoRa wireless signal transmitter 2. The data transfer station 3 transmits the data to the upper computer 4 through the Internet for centralized processing and analysis. When the detected temperature exceeds the preset value, the upper computer 4 controls the sound and light alarm 5 to give an alarm, and the sound and light alarm mode is adopted for reminder to avoid the spontaneous combustion phenomenon of the coal pile. At the same time, the upper computer 4 is connected to the remote mobile terminal 15 through a wireless signal to realize the functions of remote monitoring and alarm. The data transfer station 3 is internally equipped with a backup power supply 11 and a storage hard disk 14 to ensure stable operation and data security when the external power supply is interrupted.

[0029] The NTC thermistor plug-in temperature measuring instruments arranged at different positions of the coal pile serve as temperature sensors 1, which can sense and collect the temperature data inside the coal pile in real time. The temperature measuring rods of each temperature sensor 1 pass through the fixed collar 13 and are connected in series through the connecting belt 12, which is convenient for installation, location search and maintenance. The temperature data collected by the temperature sensor 1 is sent to the data transfer station 3 through the LoRa wireless signal transmitter 2. The LoRa wireless signal transmitter 2 has the characteristics of long distance and low power consumption, and is suitable for use in complex environments such as port yards. The wireless signal receiver 9 inside the data transfer station 3 receives the data from the temperature sensor 1. The data processor 10 processes and analyzes the received data, extracts key information and prepares to upload it to the upper computer 4. The data transfer station 3 is connected to the Internet through the wireless / wired communication interface 7 to realize data transmission with the upper computer 4. The upper computer 4 receives the data from the data transfer station 3 and displays the temperature distribution of the coal pile through the display interface. When the upper computer 4 detects abnormal temperature (such as exceeding the preset threshold), it will automatically trigger the sound and light alarm 5 to give an alarm. The upper computer 4 is also connected to the remote mobile terminal through the wireless signal to realize the real-time transmission of remote monitoring and alarm information. A backup power supply 11 is equipped inside the data transfer station 3. When the external power supply is interrupted, the backup power supply 11 automatically starts to ensure the continuous operation of the data transfer station 3. The storage hard disk 14 locally caches the monitoring data to prevent data loss and ensure data security. Through the design of the connecting belt 12 and the fixed collar 13, it is convenient to search for and replace the temperature sensor 1, reducing the maintenance cost.
