[0021] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] Refer to Figures 1 to 4 , the present utility model provides a deep hole ground temperature data collector, including a collector housing 1, a measurement channel port 3, a measurement common port 4, a measurement main board 7 and a control main board 8;

[0023] Inside the collector housing 1, the control main board 8 and multiple measurement main boards 7 are stacked and installed from front to back; the number of measurement main boards 7 in this application is not limited. In the accompanying drawings, a total of 4 measurement main boards 7 are configured. To enhance the connection stability between the control main board 8 and each measurement main board 7, the control main board 8 and each measurement main board 7 are connected and fixed through connection posts 11 located at the four corners.

[0024] Each measurement main board 7 is used to transmit the collected deep hole ground temperature data to the control main board 8. Therefore, each measurement main board 7 is electrically connected to the control main board 8; as a specific connection and assembly method, as Figure 3 shown, on the front and back sides of the bottom of the control main board 8 and each measurement main board 7, pin headers 9 and female headers 10 are assembled and installed; the pin headers 9 on the rear side of the bottom of the control main board 8 are inserted into the female headers 10 on the front side of the bottom of the adjacent first measurement main board 7; the pin headers 9 on the rear side of the bottom of the first measurement main board 7 are inserted into the female headers 10 on the front side of the bottom of the adjacent second measurement main board 7; and so on, to achieve the front and back plug-in connection between the control main board 8 and each measurement main board 7. The pin header 9 is a component with a closely arranged pin hole structure at the bottom of the control main board 8 and the measurement main board 7. Through the pin header 9 and the female header 10, the connection between the control main board 8 and the measurement main board 7 is realized, effectively reducing the number of cables and simplifying the system structure.

[0025] At the top of the collector housing 1, a measurement channel port 3 and a measurement common port 4 are installed corresponding to the position of each measurement main board 7; the measurement channel port 3 and the measurement common port 4 are electrically connected to a corresponding measurement main board 7; each measurement channel port 3 has multiple connection points, and each connection point is a collection channel. For example, in the attached drawing, each measurement channel port 3 has 32 collection points. Therefore, when 4 measurement channel ports 3 are configured, up to 128 deep-hole ground temperature sensor measurement data can be collected. The measurement common port 4 is used to connect the common line 14 of the temperature chain sensor to form a measurement loop.

[0026] As Figure 4 shown, each measurement channel port 3 is a female metal connector; for the group of measurement channel ports 3 and measurement common ports 4, the connection lines between them and multiple deep-hole ground temperature sensors are as follows: the signal lines 12 of multiple deep-hole ground temperature sensors are connected to the corresponding points on the male metal connector 13; the male metal connector 13 is plugged into the female metal connector; the common lines 14 of multiple deep-hole ground temperature sensors are uniformly connected to the measurement common port 4, thus forming a measurement loop.

[0027] Therefore, the deep-hole ground temperature sensor is connected to the female metal head of the measurement channel port 3 through the male metal connector 13. Before use, first connect the signal lines 12 of each deep-hole ground temperature sensor to the corresponding points on the male metal connector 13, then plug the male metal connector 13 onto the female metal head, and the common lines 14 of each deep-hole ground temperature sensor are uniformly connected to the measurement common port 4. After power-on, a measurement loop can be formed to complete data measurement and collection. This design can simplify wiring and reduce the complexity of installation.

[0028] In this application, the deep-hole ground temperature data collected by multiple deep-hole ground temperature sensors is first transmitted to the measurement channel port 3 through the male metal connector 13; the measurement channel port 3 then transmits the deep-hole ground temperature data to the connected measurement main board 7; the measurement main board 7 then transmits the deep-hole ground temperature data to the control main board 8. Thus, the control main board 8 can collect the deep-hole ground temperature data.

[0029] In this utility model, the deep-hole ground temperature data passes through the measurement channel port 3, the measurement main board 7, the pin header 9 and the female header 10 in sequence, and finally reaches the control main board 8. This connection method has the following advantages:

[0030] The data transmission from the measurement channel port 3 to the control main board 8 adopts the connection method of the measurement main board 7 and the pin header 9, which can effectively reduce the number of cables, simplify the system structure, and control the volume of the device; the motherboard wiring and the pin header connection can minimize the signal path, reduce the delay and attenuation in signal transmission, and the short path also helps to reduce electromagnetic interference and improve signal integrity and quality.

[0031] As a specific implementation, the control main board 8 is connected with a power supply port 2, a USB communication port 5 and a main board operation indicator light 6; the power supply port 2, the USB communication port 5 and the main board operation indicator light 6 are all assembled on the top of the collector housing 1. The detailed introduction of each component is as follows:

[0032] (1) Power supply port 2

[0033] The power supply port 2 includes two circuit interfaces, "12V" and "G", which can be respectively connected to the positive and negative poles of the power supply to supply power to the collector. The collector does not need to be separately adapted to a charger, solving the problem of difficult charging and ensuring its stable power supply under harsh field conditions.

[0034] (2) USB communication port 5

[0035] The USB communication port 5 is a communication interface for local connection with the host computer. Based on the USB Type-C interface, a serial port will be generated by the host computer after connection, and data can be transmitted and downloaded. Combined with the supporting software, the data collector can be configured.

[0036] (3) Main board operation indicator light 6

[0037] The main board operation indicator light 6 is used to indicate the operation status of the data collector. When the data collector is started, the indicator light flashes twice and lights up once every 10 seconds; when the collector measures, the USB port is connected to the host computer or the corresponding serial port is in the open state, the indicator light is on constantly.

[0038] In this application, the control main board 8 integrates multiple functional modules, including parts such as a CPU, a storage module, and a wireless communication module, and is responsible for the functions of collecting, processing, storing, and uploading data. It is the control center of the data collector. The CPU transmits the measurement instruction to the A / D conversion chip, and after being processed by the A / D conversion chip, it controls the deep hole ground temperature sensor to measure; after the measurement is completed, the deep hole ground temperature sensor transmits the measurement result back to the front-end modulation circuit in the form of an analog signal for signal filtering and noise reduction; then the analog signal is amplified by a multi-range signal amplifier module, and finally converted into a digital signal by the A / D conversion chip and transmitted to the central processing unit CPU for further processing, so as to obtain accurate and reliable data.
