Description

Technical Field

[0001] The invention relates to the technical field of mine start and stop sensors, in particular to a mine start and stop sensor timing control system and a control method thereof. Background Art

[0002] In the mining environment, the start-stop sensor is an important component for controlling the start-stop of mining equipment. Traditional mining start-stop sensor systems mostly rely on manual operation or simple automatic control methods, which cannot meet the precise needs of equipment start-stop in complex mining environments. These systems usually lack the ability to monitor and feedback the operating status of the equipment in real time, so that the sensor can only work under fixed conditions and is difficult to adapt to changing working conditions. In addition, the existing sensor system has a lag in the response speed to the equipment's operating time, inspection feedback, and equipment failures, and cannot effectively ensure the safety and efficiency of mining operations;

[0003] The existing mine start-stop sensors have exposed some problems in actual use.

[0004] First, since the start and stop time parameters cannot be adjusted in real time, the performance of the equipment in different working environments is not satisfactory, resulting in poor adaptability of the sensor to external changes;

[0005] Secondly, the fault detection and feedback mechanism of the traditional system is relatively lagging. Once the equipment is abnormal, it is often impossible to make adjustments in time, which poses a safety hazard.

[0006] Finally, the existing technology lacks the ability to process and analyze complex data, which makes it difficult for sensors to make precise control when dealing with complex mine conditions, further affecting the overall efficiency and safety of mine operations. Therefore, a timing control system and a control method of a mine start and stop sensor are proposed to address the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide a mining start and stop sensor timing control system and a control method thereof, so as to solve the problem that the start and stop time parameters cannot be adjusted in real time, the performance of the equipment in different working environments is not satisfactory, resulting in poor adaptability of the sensor to external changes and the fault detection and feedback mechanism of the traditional system is relatively lagging. Once the equipment is abnormal, it is often unable to make adjustments in time, posing a safety hazard. In addition, the existing technology lacks the ability to process and analyze complex data, resulting in sensors being difficult to make precise control when dealing with complex mine conditions, further affecting the overall efficiency and safety of mining operations.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A mine start-stop sensor timing control system and a control method thereof, comprising the following steps:

[0010] S1: Power-on self-test: After the system is powered on, the main control program automatically executes the self-test process. First, the memory chip is initialized to write and read. By comparing whether the written data is consistent with the read data, the memory status is judged. If a memory fault is detected, the system will record the fault status and stop subsequent operations.

[0011] S2: Initialize the timer and communication module: After the self-test passes, the system initializes the timer and communication module. The timer is used to generate a communication data stream at a baud rate of 2400 to ensure that the communication module can correctly process data within the timing period. The communication module is responsible for data transmission with external devices and receives and sends data through serial port interrupts.

[0012] S3: Preset time parameter control start and stop: After the timer is initialized, the system controls the start and stop operation of the mining start and stop sensor according to the preset time parameters. The timer periodically triggers the start and stop signal of the sensor through timed interruption, and adjusts the start and stop time in real time according to the operating status of the equipment to adapt to different working environments;

[0013] S4: Periodic inspection of the sensor power supply circuit: The system periodically sends inspection instructions through the COM1 port, specifies the target sensor address, and requires the sensor to return power supply status data.

[0017] S8: Data transmission and verification: The system receives the instructions and status data sent by the external device through the serial port interrupt of the communication module. After the data is received, it enters the data processing module for verification. The system uses the CRC verification algorithm to detect data integrity to ensure that the data is not disturbed during the transmission process;

[0018] S9: Automatic adjustment algorithm of timer parameters: The system dynamically adjusts the control parameters of the timer according to the feedback information of the inspection subroutine and the equipment status. The automatic adjustment algorithm formula is:

[0019]

[0020] Where f(t) is the sensor response time, T is the timing period, and R i is the response time of the ith sensor, n is the number of sensors;

[0021] This algorithm ensures the real-time response of the sensor and makes adaptive adjustments to different working environments;

[0022] S10: Host computer feedback and status monitoring: After the inspection and data processing are completed, the system sends the status information of the equipment to the host computer through the communication module for recording and monitoring. If the host computer detects that the equipment status is abnormal, it will automatically adjust the equipment control parameters and send new control instructions to the system.

[0030] As a further optimized content of the present invention, wherein: the communication module receives interface instructions through serial port interruption and I / O timer control, sends control commands and receives external sensor data.

[0031] As a further optimized content of the present invention, the data processing module performs regular inspection on the sensor power supply circuit, uses the COM1 port to send inspection address instructions, and receives data returned by the designated address sensor for verification.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1.
