Background
In the coal mine production accidents in China, the mine flood is the second largest mine disaster next to the gas accident. Generally, casualties caused by water disasters are heavy, and the economic loss caused by water disasters is also very large. Since 1949, thousands of people died from nearly 30 accidents in coal mines, which died more than 30 people due to flood disasters. Economic loss and casualties caused by flood in coal mines can be called eye-catching and surprise. It is therefore entirely necessary to design a well-designed water level monitoring system. At present, most mine water level monitoring systems are complex in structure and cannot monitor water levels remotely.

Detailed Description
In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples thereof.
The technical solutions of the embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in fig. 1, the invention provides a computer-based remote mine water level monitoring system, which comprises an upper computer, a computer, an a/D converter, a system bus, a keyboard, a display unit, an alarm control unit and a water pump control unit; the upper computer is in wireless connection with the computer; the computer takes a singlechip AT89C52 as a core; the computer is respectively connected with the display unit, the alarm control unit and the water pump control unit; the A/D converter, the system bus and the keyboard are electrically connected with a computer respectively; the water level sensor is connected with the A/D converter.
According to one aspect of the invention, the system bus is a CAN bus.
According to one aspect of the invention, the display unit is a liquid crystal display.
According to one aspect of the invention, a CAN bus comprises a CAN/PCI card and a communication node; the communication node comprises a photoelectric isolator, 28C250, SJA1000 and an MCU; the photoelectric isolator, the 28C250, the SJA1000 and the MCU are electrically connected in sequence.
The system adopts LabVIEW as an upper computer control program, and monitors and controls the water pump on site by utilizing the single chip microcomputer. In the hardware control part, the water level is monitored by using an AT89C52 singlechip. Signals measured by the field sensor are transmitted to the single chip microcomputer, the single chip microcomputer is compared with a low limit value, if the signals are higher than the low limit value, part of the water pumps are started to pump water, and meanwhile, an alarm is given; and if the field water level exceeds the high limit value, all the water pumps are started to drain water, and meanwhile, the alarm is continued.
The system adopts a photoelectric coupler to form a switch circuit to drive the relay to be opened and closed, a relay control circuit diagram is shown in figure 2, and the circuit mainly comprises the photoelectric coupler, a relay switch and a water pump. When the water level is higher than the upper limit, the single chip microcomputer sends a high level, the photoelectric coupler is conducted, the Q3 is driven through the photoelectric coupler to enable the relay to be closed, and therefore 380V alternating current is conducted to enable the water pump to pump water.
The monitoring system can monitor the field water level, and meanwhile, the upper computer software adopts LabVIEW, so that more control interfaces can be developed according to the field reagent condition, the hardware investment is reduced, the stability and the reliability of the system are ensured, and the remote monitoring of the mine water level is realized.
The invention is not limited to the above-described examples, and various modifications or alterations without inventive work may be made by those skilled in the art within the scope of the invention defined by the claims appended hereto.
