Description

Technical Field

[0001] The present invention relates to the technical field of data monitoring equipment and application methods, and in particular to a data monitoring system and application method for remotely controlled lifting equipment at a port terminal. Background Art

[0002] Port terminal lifting equipment mainly includes portal cranes, bridge cranes, tire cranes, container cranes, gantry cranes running along fixed tracks (track-type lifting equipment), etc. In general, track-type lifting equipment is manually driven by drivers. With the development of technology, based on the data collected by on-site cameras, the technology of remote wireless control of lifting equipment by drivers in studios far away from the site has also developed rapidly. This control mode brings convenience to drivers and reduces production costs accordingly.

[0003] The existing technology usually uses the images sent back by the camera to perform the corresponding wireless remote control operation of the rail-type lifting equipment. In fact, due to the limitation of the camera's viewing angle and the fact that only the visible image data of the on-site staff and related equipment can be observed, the data obtained by the staff in the studio is relatively single, and there are still major deficiencies and safety hazards in the remote wireless remote control of the rail-type lifting equipment, etc., as shown below. The staff in the studio cannot intuitively understand the height data of the hoisted cargo, the speed data of the rail-type lifting equipment, the weight data of the hoisted cargo, whether the rail-type lifting equipment is reliably parked at the lifting or unloading station, the working temperature data of the motor, and whether the wire rope is broken, whether there are unrelated personnel approaching the front end of the lifting equipment wheels, etc. This will not only have an adverse effect on the work of the wireless control equipment, but also have certain safety hazards (for example, if the wire rope is broken, the relevant personnel do not replace it in time, the wire rope suddenly breaks during the subsequent hoisting, causing a safety accident, the motor temperature rises too high due to a fault or excessive load, and it is not maintained in time, resulting in the expansion of the fault, etc.). The following content of this article refers to the lifting equipment as the abbreviation of rail-type lifting equipment. Summary of the invention

[0025] Figure 1 , 2As shown in Figures 3, 4, and 5, the application method of the data monitoring system for remotely controlling the lifting equipment of the port terminal is as follows. After the AC 220V power supply enters the power input terminal of the power module A1, the 3rd and 4th pins of the power module A1 will output a stable DC 12V power supply to enter the power input terminal of the hoisting cargo height monitoring circuit, the driving speed monitoring circuit, the hoisting cargo weight monitoring circuit, the hoisting equipment position monitoring circuit, the motor temperature monitoring circuit, the wire rope broken wire monitoring circuit, the personnel approach monitoring circuit and the data transmission circuit, and the above circuits are powered on. After the hoisting cargo height monitoring circuit is powered on, when the height of the hoisting cargo on the hook changes, the distance between the detection head of the laser ranging module A2 and the lower end of the hoisting motor 105 will change. The larger the distance between the cargo and the motor (the lower the height from the ground), the higher the voltage signal output by the laser ranging module A2. Conversely, the lower the voltage signal (the higher the height from the ground), the voltage signal is divided by the adjustable resistor RP1 and the resistor R1, and the resistor R2 steps down and limits the current to enter the 9th pin of the single-chip module A6. After the driving speed monitoring circuit is powered on, when the lifting device 10 moves forward or backward, its wheel shaft will drive the contact wheel 31 to drive the generator M2 to rotate, and then the generator M2 outputs a dynamically changing voltage signal that enters the power input end of the bridge pile A10. The bridge pile A10 converts the AC power into a DC power supply, which is divided by resistors R3 and R4, and the resistor R5 reduces the voltage and limits the current to enter the 5th pin of the single-chip module A6. The faster the driving speed, the higher the voltage signal, and vice versa. After the lifting cargo weight monitoring circuit is powered on, the greater the lifting weight, the higher the voltage signal output by the gravity sensor A5, and vice versa, the lower the output voltage signal. The voltage signal is divided by the adjustable resistor RP2 and the resistor R19, and the resistor R20 reduces the voltage and limits the current to enter the 3rd pin of the single-chip module A6. When the hoisting equipment position monitoring circuit is working, when the hoisting equipment moves forward to the operation point or moves backward to the unloading point, the magnetic force of a magnet CT at the front end or a magnet CT1 at the rear end will act on the reed switch GH or GH1, and the internal contacts of the reed switch GH or GH1 will close. In this way, the 12V voltage signal will enter the 8th pin of the single-chip module A6 through the voltage division of resistors R6 and R7, and the voltage reduction and current limiting of resistor R8, or the 12V power supply will enter the 7th pin of the single-chip module A6 through the voltage division of resistors R9 and R10, and the voltage reduction and current limiting of resistor R11. After the motor temperature monitoring circuit is powered on, the voltage signal output by the infrared thermometer A4 probe at pin 3 is relatively high when the motor housing temperature is high, and relatively low otherwise. The voltage signal enters the 7th pin of the single-chip module A6 through the voltage division of adjustable resistors R15 and R16, and the voltage reduction and current limiting of resistor R17.After the wire rope broken wire monitoring circuit is powered on, when the wire rope 106 is not broken, due to the relatively small outer diameter of the wire rope, even if one end of the wire rope contacts the contact pieces S1 or S2, S3, S4 (but will not contact S1 and S3 or S2 and S4 at the same time), the low level output from the 4th pin of the power module A1 enters the contact piece S3 or S4, but because the contact piece S1 is connected to the negative power input terminal of the relay K1, the contact piece S4 is connected to the negative power input terminal of the relay K2, the positive power input terminals of the two relays K1 and K2 are connected to the control power input terminal, the normally open contact terminals of the first relay K1 and the second relay K2 and the first resistor R12 are connected. The ends are connected, so the relay K1 or K2 will not be energized to close the control power input end and the normally open contact end, and will not cause the other end of the resistor R12 to be energized, and the 4th pin of the single-chip module A6 will not input a high-level signal; in actual circumstances, when the wire rope 106 is broken, due to the relatively larger outer diameter of the wire rope, the front and rear ends of the wire rope contact the contact pieces S2 or S4, or the left and right ends of the wire rope contact the contact pieces S1 or S3, the relay K1 or K2 will be energized to close the control power input end and the normally open contact end, so that the 12V power supply will enter the 4th pin of the single-chip module A6 through the voltage division of the resistors R12 and R13 and the voltage reduction and current limiting of the resistor R14. After the personnel approach monitoring circuit is energized and working, when no one approaches the range of about 10 meters in front of the lifting equipment, the 3rd pins of the four sets of millimeter wave detection modules A8 will not output a high level to the 10, 11, 12, and 13 pins of the single-chip module A8; when someone approaches the range of about 10 meters in front of the lifting equipment, the 3rd pins of one or more sets of the four sets of millimeter wave detection modules A8 will output a high level, which will be divided by resistors R21 and R22, and the resistor R23 will reduce the voltage and limit the current to enter the 10th pin or the 11, 12, and 13th pins of the single-chip module A8. Under the action of its internal circuit, the single-chip microcomputer module A6 converts the analog voltage signal inputted by its 3rd or 4th, 5th, 6th, 7th, 8th, 9th, 10th, 11th, 12th, 13th pin into a digital signal and outputs it to the 5G data transmission module A7, which transmits the input multi-channel digital signal wirelessly; the receiving module receives the data of the height of the hoisted cargo from the ground, the speed of the hoisting equipment, the weight of the hoisted cargo, the position of the hoisting equipment, the temperature of the motor, the broken wire of the wire rope, and the data of the wheel of the unrelated personnel approaching the hoisting equipment transmitted by the data transmission circuit, and transmits the above data to the analysis module after preliminary processing. The analysis module analyzes and processes the received data and displays it on the screen through the display module, and generates an alarm sound signal through the alarm prompt module to prompt the personnel in the studio when there is an abnormal data. In this way, the staff can observe the corresponding data in real time and coordinate the wireless control of the hoisting equipment, and because it can prompt the personnel in the studio in time when the relevant data is abnormal, it brings convenience to the staff and reduces the occurrence of safety accidents accordingly.

[0026] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in the embodiments can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
