Description

Monitoring system and method for mining inclined roadway transportation based on radio frequency technology

technical field

The present invention relates to a mining inclined roadway transportation monitoring system and method based on radio frequency technology. "Radio Frequency Technology-Based Mine Inclined Roadway Transportation Monitoring System and Method. the

Background technique

According to the requirements of "Code for Use and Management of Coal Mine Underground Workers Management System" (AQ1048-2007): All personnel entering the mine must carry identification cards (or wireless communication devices with positioning functions). Coal mine transportation management system requires: "Pedestrians must not drive, vehicles must not pass pedestrians" in the winch lane, that is, in winch transportation, vehicles and pedestrians are not allowed to drive at the same time. At present, the solutions for this situation in coal mines are as follows: the first is to manually check the personnel information in the roadway. The second is to detect personnel information in the roadway through infrared sensors.

Through artificial inspection of personnel information in the roadway, due to the dark light in the roadway, the long roadway with certain slopes, openings and inflection points, the inspectors’ sight is blocked, and the distance of sight is affected to a certain extent, so it is easy to be negligent during the inspection; during the inspection process, The entire roadway is always open. When inspectors inspect an area and go to the next area to inspect, personnel may enter the inspected area through the opening, so the real-time accuracy of the inspection of the entire roadway cannot be guaranteed. In addition, when the winch is running, the voice alarm is used to inform personnel not to enter the roadway, but for some people with weak safety awareness or fluke mentality, it is inevitable that they will enter the roadway. When a person enters the roadway, the winch driver cannot know that the person has entered the roadway, and it is difficult for winch transportation to meet the requirements of "pedestrians are not allowed to drive, and vehicles are not allowed to be pedestrians" in the roadway. At the same time, it not only consumes a lot of time and labor to check the personnel information in the roadway, but also cannot guarantee the accuracy of the inspection information, and it is difficult to avoid the problem of simultaneous driving and pedestrians in the roadway.

The infrared sensor detects personnel information in the roadway. The principle is shown in Figure 1. The infrared detection sensors are respectively placed at the mouth, nose, and tail of the machine. Leaving the lane, the controller calculates and knows the number of people in the lane. When the number of people in the roadway is greater than 0, it is considered that there are people in the roadway, and it is forbidden to start the winch; when the winch is running, touch sensor A and sensor B, it is judged that someone has entered the roadway, and the winch stops running, so that there are people in the roadway and the winch does not run. When the winch is running, someone enters and stops the operation. Due to the relatively random behavior of personnel, when multiple people pass by the sensor side by side and enter the roadway, the sensor will only record one person passing through after receiving a signal, and the controller will record the information of one person, so the recorded information will be inaccurate . When the goods pass through the sensor, the sensor will output a response, and the controller will receive the signal and count, but the count will also be inaccurate. Therefore, this method cannot accurately obtain the information status of personnel in the roadway, and cannot fundamentally realize "pedestrians must not drive, and vehicles must not pass pedestrians". the

Contents of the invention

In order to overcome the shortcomings of the above-mentioned technical problems, the present invention provides a monitoring system and method for mining inclined roadway transportation based on radio frequency technology.

The readers are evenly distributed in the coal mine roadway and communicate with the controller 1 through the communication cable 5. The reader 2 can identify and read the information in the personnel positioning card 8. The personnel positioning card 8 is an RFID radio frequency identification card, which is used by coal miners carry.

Both the shown display 4 and the voice broadcast unit 6 are connected to the output end of the controller 1, and the display 4 is used for displaying data information, such as the operation data of the winch and the like. The voice broadcast unit can send voice information to remind personnel to warn and guide the staff. The shown control input unit 7 is connected with the input end of the controller 1, and the control input unit 7 includes a stop button and an emergency stop button for controlling the winch; the output unit 3 is connected with the output end of the controller 1, and the output unit 3 is for controlling The circuit part of the winch operation, the controller 1 can control the start, operation and stop of the winch through the output unit 3 .

As shown in Fig. 3 and Fig. 4, provide the flow chart of the control method of the mining inclined roadway transportation monitoring system based on radio frequency technology of the present invention, it is realized through the following steps:

a). Judgment of positioning card information. The controller identifies and collects the positioning card information carried by the personnel through the reader, and judges the location of the personnel; If the conditions for winch operation are not met, record and send out a voice broadcast, and continue to detect; if it is detected that there is personnel positioning card information in the winch console area, but there is no personnel in the coal mine roadway, then perform step b);

When the winch is not started, through the reader's identification of the location card of the surrounding personnel, if it is detected that there are people in the roadway, it means that the conditions for starting the winch are not available at present. If there is no person in the roadway, but there is a person in the winch control area, the identity information of the person needs to be verified.

b). Determine whether the Trinity is valid. When it is detected that there are people around the winch console, determine whether it is necessary to confirm the shift monitor, security inspector and winch driver. If confirmation is required, perform step c); if no confirmation is required, perform step d);

In this step, the trinity refers to whether the monitor on duty, the security inspector and the winch driver confirm the current situation and whether it is conducive to the safe operation of the winch.

c). Judging whether all have been confirmed, and judging whether the detected personnel location card information contains the information of the monitor on duty, the security inspector and the winch driver. Confirm the safety with the winch driver, if you have the conditions for safe start of the winch, go to step e); if the information of one of the three persons is not included, it means that you do not have the conditions for safe start of the winch, skip to step a) ;

In the process of judging the Trinity, it is necessary for the monitor on duty, the security inspector and the winch driver to confirm it. If the safety confirmation of one person is missing, it is regarded as not having the conditions to start the winch safely.

d). Determine whether the winch driver exists, judge whether the information of the detected personnel positioning card contains the information of the winch driver near the console, if it exists, it indicates that there is a winch driver on the winch console, allow the winch to start, and perform step e );

If there is no need for trinity confirmation, it is only necessary to detect whether the winch driver is off his post.

e). The winch is started, and the winch driver starts the winch through the winch console, so that the winch drives the mine car for transportation;

f). Judgment of the prompt area. During the operation of the winch, the controller collects and judges the information of the surrounding personnel positioning cards through the reader. The voice broadcasting unit makes voice broadcasts to remind personnel to stay away from the driving roadway and not to execute parking; if there is no personnel present, the winch is kept in the running state;

During the operation of the winch, if a person appears at the mouth of the roadway, the nose or the tail of the machine, it is not regarded as a situation that must be stopped, and it is sufficient to issue a warning for the person to stay away from the driving roadway at this time.

g). Judgment of prohibited areas. During the operation of the winch, the controller collects and judges the information of the surrounding personnel positioning cards through the reader. If it is judged that there are people in the prohibited pedestrian area in the roadway, the controller automatically stops the winch The operation of the winch will record the parking information and send out a voice alarm signal; if there is no personnel present, the winch will remain in operation;

During the operation of the winch, if it is detected that there is a person in the pedestrian-prohibited area of the roadway, it is deemed necessary to stop, and the controller stops the winch through the output unit.

h). Judgment of the driver leaving the post. During the operation of the winch, the controller judges whether there is the driver's location card information in the winch console area through the reader. If there is no driver's personnel location card information, it indicates that the driver has left the post and stops the winch It will record the parking information and issue a voice alarm signal; if there is a winch driver, it will keep the winch running.

During the operation of the winch, if it is detected that the winch driver is off his post, it is also considered as a situation that must be stopped, and the controller stops the operation of the winch through the output unit.

After the winch driver learns that the traffic prohibition occurs in the roadway, he can stop the operation of the winch through the emergency stop button; when the normal parking conditions are met, he can stop the operation of the winch through the stop button. the
