Problems solved by technology

However, all the existing subglacial environment detectors can only detect and cannot obtain in-situ samples of the subglacial water body and recover the samples. The main problem is that after melting into the ice for a period of time, the ice hole will freeze again, so it cannot be recovered and detected equipment
In addition, since the subglacial lake detector needs to work under the ice for a long time, if the measurement and control system fails, the detector will not be able to complete the task, and may even be unable to recover, so improving the reliability of the detection and control system of the detector is also very important

Embodiment 1

[0056] see figure 1 Shown is the functional block diagram of the master-slave double-backup subglacial lake recoverable detector measurement and control system in the first embodiment. It includes a host computer 10, an above-ice carrier machine 20, an under-ice wave machine 30, an RS232 hub 416, a main control board 40 and a slave control board 50,

[0057] Among them, the above-ice wave machine 20 receives the instructions sent by the host computer 10, and communicates with the ice wave machine 30, and transmits data in two directions; The control board 50 is connected, the address of the main control board 40 is 0x01, and the address of the slave control board 50 is 0x02; the above-ice wave machine 20 sends the address data 0x01 to the RS232 hub 416 through the ice wave machine 30, and the main control board 40 returns the measured data ; The above-ice carrier wave machine 20 sends to the RS232 hub 416 address data 0x02 through the ice wave wave machine 30, and returns the...

Embodiment 2

[0063] see image 3 It is the principle block diagram of the heating control system in the master-slave double-backup subglacial lake retrievable detector measurement and control system in Example 2 of the present invention. Considering the need to carry out gradient heating on the subglacial lake detector, that is, it is necessary to adjust the drill bit and the side wall The different heating powers of the heating wire can only be adjusted according to several power levels if the relay switching method is adopted, which is not flexible enough. The present invention uses a thyristor power regulator 701 to adjust the power of the heating wire, and simultaneously connects a relay 703 in parallel for heating control. double backup. The high-voltage power supply on the ice surface is 2500VAC. Due to the transmission loss of the 2500-meter transmission cable, the input voltage reaching the detector end is 2200-2300VAC. Connected to the input terminal 1 and input terminal 2 of the...

Embodiment 3

[0066] see Figure 4 It is the principle block diagram of the observation system in the master-slave dual-backup type subglacial lake retrievable detector measurement and control system in Embodiment 3 of the present invention. The observation system 801 includes a control circuit board 803, a temperature sensor 804, a camera temperature control heating wire 805, an SD Memory card 806, embedded video recorder 807, high-definition camera 808, lighting 809, serial camera 810 and lake water parameter measurement sensor 811, wherein the lake water parameter measurement sensor 811 is used to measure the physical and chemical parameters of the subglacial lake water, such as temperature, conductivity, pH value, etc.; the serial port camera 810 is a camera with an integrated RS485 transmission interface, which can directly read the photos taken by the serial port camera 810 through the RS485 interface; in the self-capacitance camera system 801, when the detector enters the subglacial l...

Abstract

The present invention discloses a main-slave dual-standby subglacial lake recoverable detector measurement and control system and method. The system comprises an upper computer, an on-ice carrier machine, a subglacial carrier machine, a RS232 concentrator, a main control panel and a slave control panel. The main control panel and the slave control panel are a main-slave relation at normal work, the slave control panel assists in collection of data, the main control panel takes on a role of 'main control' and is configured to control a winch and a heating control system and send the data collected by itself of the main control panel and the data collected by the slave control panel to the upper computer; and when the main control panel has faults, it is automatically switched that the slavecontrol panel takes on a role of 'main control' and is configured to control the winch and the heating control system and send the collected data to the upper computer. The main-slave dual-standby subglacial lake recoverable detector measurement and control system and method employ a main-slave dual-standby mode to perform detection of detector state information such as a temperature, a pressureand posture and perform gradient heating control and winch control so as to improve the long-term work reliability of a subglacial lake detector.

Description

technical field [0001] The invention belongs to the field of electronic control systems, and in particular relates to a master-slave double-backup subglacial lake recoverable detector measurement and control system and method. Background technique [0002] There are subglacial lakes under the ice of Antarctica. The Antarctic subglacial lake has an important impact on the movement and stability of the Antarctic ice sheet, and its water environment may provide unique information on microbial evolution, Earth's paleoclimate, and the formation and evolution mechanism of the Antarctic ice sheet. Currently, scientists are trying to understand the formation and evolution process of the Antarctic subglacial lake and the impact of the Antarctic subglacial lake on the mass balance of the ice sheet. The solution to the problem requires a key—obtaining in-situ detection data of physical and chemical parameters of subglacial lake water, and directly obtaining non-polluting subglacial la...
