Description

Technical Field

[0001] The present invention relates to an operation management system and an early warning method for park transport vehicles, belonging to the technical field of park safety management. Background Art

[0002] With the continuous expansion of the scale of the park, it is difficult to maximize the efficiency of material allocation only by manpower in a short time. Under this background, the demand for transport vehicles is increasing continuously. However, accidents caused by drivers' non-standard driving, fatigue driving, etc. occur frequently, which not only disrupts the normal production order in the park, resulting in huge economic losses, but also poses a serious threat to the lives and safety of the staff.

[0003] Therefore, it is particularly important to be able to monitor the real-time situation of the operation and give timely reminders for situations such as drivers' non-standard driving. Scientifically and effectively detecting the vehicle operation status, discovering and disposing of situations such as non-standard driving has important significance for safe production.

[0004] At present, the monitoring of non-standard driving behaviors in the park mainly relies on manual real-time monitoring or daily patrol inspections, etc., which consume a large amount of manpower and material resources and have a poor monitoring effect. Summary of the Invention

[0005] The purpose of the present invention is to provide an operation management system and an early warning method for park transport vehicles, which can monitor the driving state of the driver and the vehicle operation state, achieve early warning in key areas, and enable the background monitoring personnel to actively intervene and dispatch to ensure driving safety.

[0006] To solve the above problems, the technical solution adopted by the present invention is: An operation management system for park transport vehicles, including

[0007] A vehicle behavior monitoring system, including a vehicle speed monitoring unit for monitoring the driving speed of the vehicle, a vehicle load monitoring unit for detecting the mass of the goods loaded on the vehicle, and a GPS high-precision positioning monitoring unit for monitoring the real-time position of the vehicle;

[0008] An operator monitoring system, including a first monitoring unit for detecting the number of vehicle operators and a second monitoring unit for monitoring whether the operators wear safety helmets and work clothes correctly;

[0009] A key equipment operation (key area) monitoring system, including a regional monitoring unit and an early warning unit for key areas, monitoring the road conditions in the vicinity and the vehicles entering the key area, and capturing the vehicle information of the vehicles driving in the key area;

[0010] A monitoring and alarm system is used to collect and analyze the detection data of a vehicle behavior monitoring system, an operator monitoring system, and a key equipment operation (key area) monitoring system, and give an alarm reminder when the detected data exceeds the set threshold.

[0011] A command system is used for communication between backstage monitoring personnel or professional safety rescue personnel and operators.

[0012] As a further improvement of the present invention, the operator monitoring system further includes a fatigue driving monitoring unit that monitors the driver's body movements, blink frequency, and eye opening and closing states to determine and analyze whether the driver is fatigued.

[0013] As a further improvement of the present invention, the monitoring and alarm system includes a display system composed of a vehicle behavior status indication unit, an operator status indication unit, and a key equipment operation (key area) status indication unit. The vehicle behavior status indication unit is used to display the running status of the vehicle, the operator status indication unit is used to display the status of the operator's proper dressing and the presence or absence of fatigue driving, and the key equipment operation (key area) status indication unit is used to display the safety status of vehicles and personnel in the key area and the presence or absence of illegal entry into the key area.

[0014] As a further improvement of the present invention, the vehicle running status displayed by the vehicle behavior status indication unit includes in motion, parked, malfunctioning, speeding, and overloading.

[0015] As a further improvement of the present invention, the key equipment operation (key area) monitoring system further includes a vehicle position detection unit and a warning sign unit;

[0016] The vehicle position detection unit includes a signal transmitter installed on the work vehicle and a signal receiver installed near the key area. The signal receiver receives the signal sent by the signal generator and controls the operation of the monitoring and alarm system;

[0017] The warning sign unit includes traffic indication signs set near the key area.

[0018] As a further improvement of the present invention, the signal receiver is installed 5 - 20 meters outside the key area.

[0019] As a further improvement of the present invention, there are two vehicle signal transmitters, which are respectively installed at the front and rear ends of the vehicle for quick signal pairing with the signal receiver.

[0020] As a further improvement of the present invention, the monitoring and alarm system further includes a background operator management system and an IC card management system. The IC card management system includes a reading device installed on the transport vehicle and an IC card matched with the operator. The IC card records the operator information and the continuous driving duration. The background operator management system includes the basic operator information and the cumulative driving duration.

[0021] The operation warning method for the park transport vehicle of the present invention includes the following steps:

[0022] S1: Obtain the driving speed and the quality of the loaded goods of the vehicle through the vehicle speed monitoring unit and the vehicle load monitoring unit of the vehicle behavior monitoring system, and transmit them to the monitoring and alarm system. The monitoring and alarm system compares the obtained data with the pre-set thresholds of the vehicle speed and the load. If the monitored value exceeds the threshold, it will be displayed on the vehicle behavior status indicating unit according to the corresponding status. The background monitoring personnel will contact the corresponding staff through the command system in the first time and report the relevant problems to them;

[0023] S2: During the vehicle operation, collect the images in the cab and the driver status data through the fatigue driving monitoring unit of the operator monitoring system. Display the images in the cab on the display system, and collect and extract the features of the driver's image through the fatigue driving monitoring unit. Judge the working status of the driver according to the blink frequency and the eye opening and closing status. If it is determined as fatigue driving, the image in the operation cab will be enlarged and displayed in the monitoring and alarm system. The background monitoring personnel will view the real-time picture for manual confirmation. If it is confirmed as fatigue driving, the background monitoring personnel will communicate with the operator through the command system;

[0024] S3: During the vehicle operation, use the GPS high-precision positioning monitoring unit of the vehicle behavior monitoring system to monitor the position and driving route of the vehicle. When the vehicle drives near the signal receiver, the signal emitted by the signal transmitter on the work vehicle is received and recognized by the signal receiver, and then the monitoring and alarm system warns the information of this key area and guides the driver to pass through this area correctly;

[0025] S4: The key equipment operation (key area) monitoring system monitors the actual situation near the key area and displays it on the display system. If the vehicle position detection unit detects that a vehicle needs to enter this key area, the display system will enlarge and display its picture. The background monitoring personnel will view the vehicle information through the enlarged picture and track and judge the vehicle speed and vehicle position information, and timely conduct command and dispatch through the command system;

[0026] S5: If the continuous driving duration of the driver exceeds the set duration, give a warning reminder to the driver, and feedback this information to the background monitoring and alarm system. The background monitoring personnel will conduct dispatch through the command system.

[0027] In summary, the beneficial effects of the present invention are as follows: By setting up a vehicle load monitoring unit, the present invention can prevent the vehicle from operating in an overloaded state, reducing the driving risk. By setting up a vehicle speed monitoring unit to monitor the vehicle speed, it can prevent the vehicle from speeding, further reducing the driving risk, and ensuring that the vehicle operates under the good conditions of not being overloaded and not speeding. Through the manual intervention of the background monitoring personnel, it can effectively stop and pre-intervene in the irregular behaviors of the driver to avoid accidents. By setting up a key equipment operation (key area) monitoring system, when the vehicle drives near the corresponding area, it can receive corresponding warning reminders and correct operation reminders, ensuring that the vehicle can smoothly pass through this key area. The present application combines multiple warning means to assist the driver in driving safely and regularly, thereby realizing the safe operation of the transport vehicle.

[0038] As Figure 4 and Figure 6 shown in the figure, the key equipment operation (key area) monitoring system includes a regional monitoring unit and an early warning unit for the key area, which monitors the road conditions in the vicinity and the vehicles entering the key area, and captures the vehicle information of the vehicles driving in this key area. In the present invention, the regional monitoring unit is at least two key area monitoring cameras installed on the vehicle roof, and the early warning unit is an audible and visual alarm light installed in the vehicle cab.

[0039] As Figure 5 shown in the figure, the monitoring and alarm system is used to collect and analyze the detection data of the vehicle behavior monitoring system, the operator monitoring system, and the key equipment operation (key area) monitoring system, and gives an alarm reminder when the detected data exceeds the set threshold.

[0040] The command system is used for communication between the background monitoring personnel or the professional safety rescue personnel and the operators. In the present invention, an intercom is installed in the vehicle cab to facilitate communication between the operators and the background monitoring personnel or the professional safety rescue personnel, as Figure 6 shown in the figure.

[0041] The monitoring and alarm system in the present invention includes a display system composed of a vehicle behavior status indicating unit, an operator status indicating unit, and a key equipment operation (key area) status indicating unit. The vehicle behavior status indicating unit is used to display the operation status of the vehicle, including the vehicle being in driving, parking, malfunction, speeding, overloading, and the real-time position information of the vehicle. The operator status indicating unit is used to display the number of operators, the status information of the operators' standard dressing, and the status information of whether the operators are fatigued. The key equipment operation (key area) status indicating unit is used to display the safety status of the vehicles and personnel in the key area when the vehicle enters the key area, and display the status of whether there are vehicles and personnel illegally entering this key area.

[0042] The monitoring system for the operation of key equipment (key area) in the present invention further includes a vehicle position detection unit and a warning sign unit. The vehicle position detection unit includes a signal transmitter installed on the working vehicle and a signal receiver installed near the key area. The signal receiver receives the signal emitted by the signal generator and controls the operation of the monitoring and alarm system. The warning sign unit includes traffic indication signs set near the key area. The signal receiver in the present invention is installed 5 - 20 meters outside the key area. There are two vehicle signal transmitters in the present invention, which are respectively installed at the front and rear ends of the vehicle for quickly pairing with the signals of the signal receiver. For example, Figure 6 as shown.

[0043] For example, Figure 5 as shown, the monitoring and alarm system in the present invention further includes a background operator management system and an IC card management system. The IC card management system includes a reading device installed on the transport vehicle and an IC card matched with the operator. The IC card records the operator information and the continuous driving duration. The background operator management system includes the basic information of the operator and the cumulative driving duration.

[0044] The operation warning method for the park transport vehicle of the present invention uses the aforementioned operation management system for the park transport vehicle, and includes the following steps:

[0045] S1: Obtain the driving speed and the quality of the loaded goods of the vehicle through the vehicle speed monitoring unit and the vehicle load monitoring unit of the vehicle behavior monitoring system, and transmit them to the monitoring and alarm system. The monitoring and alarm system compares the obtained data with the preset thresholds of vehicle speed and load. If the monitored value exceeds the threshold, it will be displayed on the vehicle behavior status indication unit according to the corresponding status. The background monitoring personnel will contact the corresponding staff through the command system in the first time, report the relevant problems to them, and end the call after meeting the regulations.

[0046] S2: During the operation of the vehicle, collect the images in the cab and the driver status data through the fatigue driving monitoring unit of the operator monitoring system, display the images in the cab on the display system, and collect and extract the features of the driver's image through the fatigue driving monitoring unit. Judge the working status of the driver according to the blinking frequency and the opening and closing state of the eyes of the operator. If it is determined that the operator is in a fatigue driving state, the image in the cab will be enlarged and displayed in the monitoring and alarm system. The background monitoring personnel will view the real-time picture for manual confirmation. If it is confirmed by manual confirmation that the operator is indeed in a fatigue driving state, the background monitoring personnel will communicate with the operator through the command system.

[0047] S3: During the operation of the vehicle, use the high-precision GPS positioning and monitoring unit of the vehicle behavior monitoring system to monitor the vehicle's position and driving route. Cooperate with the key equipment operation (key area) monitoring system to ensure that the vehicle travels on a route that can safely pass through the key area. When the vehicle travels near the signal receiver, the signal emitted by the signal transmitter on the operating vehicle is received and recognized by the signal receiver, and then the monitoring and alarm system warns of the key area information and guides the driver on the safe operation method to correctly pass through the area.

[0048] S4: The key equipment operation (key area) monitoring system monitors the actual situation near the key area and displays it on the display system. If the vehicle position detection unit detects that a vehicle needs to enter the key area, the display system will magnify and display its picture. The background monitoring personnel view the vehicle information through the magnified picture and track and judge the vehicle speed and vehicle position information, and timely conduct command and dispatching through the command system.

[0049] S5: If the continuous driving duration of the driver exceeds the set duration, give a warning reminder to the driver and feedback this information to the background monitoring and alarm system, and the background monitoring personnel conduct dispatching through the command system.
