The weighing module comprises a weighing platform 21, a second infrared detector 22 and a second recognizer 23. Wherein the weighing platform 21 is disposed in the platform 20, and the carrying vehicle is weighed when the carrying vehicle is stopped on the weighing platform 21. The transmitting end and the receiving end of the second infrared detector 22 are respectively arranged at two sides of the weighing wagon balance 21, the working principle of the second infrared detector 22 is similar to that of the first infrared detector 14, and when the receiving end of the second infrared detector 22 cannot receive the infrared rays transmitted by the transmitting end, a carrying vehicle is confirmed to be on the wagon balance. The second recognizer 23 is arranged at an entrance of the weight house 20, the working principle of the second recognizer is similar to that of the first recognizer 15, when the carrying vehicle enters the weight house 20, the second recognizer 23 recognizes the identity information of the vehicle, and when the carrying vehicle is weighed by the weighing wagon balance 21, the weight of the carrying vehicle is bound with the identity information of the vehicle and is recorded into the system.

In the process of carrying mineral aggregate by a carrying vehicle, the situation that the carrying vehicle is overweight in order to reduce the transportation cost or steal the mineral aggregate by part of vehicles not only can cause the loss of the mineral aggregate, but also more importantly, the potential safety hazard in the driving process of the vehicle can be greatly increased by the overweight transportation of the vehicle, and traffic safety accidents are caused. To prevent this, in a further embodiment the monitoring system further comprises a pouring module, which, in connection with fig. 4, comprises a mineral site 40 and a third identifier 41, wherein the third identifier 41 is arranged at the entrance of the mineral site 40. When the weighing wagon balance 21 detects that the carrying vehicle is overweight, the service analysis module confirms that the carrying vehicle is in an illegal service state, and indicates the overweight vehicle to go to the mineral aggregate site 40 for unloading so as to ensure the driving safety. The overweight vehicle goes to the mineral aggregate site 40, the third recognizer 41 recognizes the identity of the vehicle entering the mineral aggregate site 40, and the information record of the overweight vehicle entering the mineral aggregate site 40 is further stored in the storage unit for subsequent inquiry. Through such setting guarantee that the vehicle that gets into mineral aggregate place 40 is the overweight vehicle of violation, prevent that other no-load vehicles or not overweight vehicle from getting into mineral aggregate place 40 and feed, avoid the mineral aggregate loss in mineral aggregate place 40.
At present, some vehicle carrying systems generally adopt an OCR (Optical Character Recognition) scanning device to scan a license plate to confirm vehicle identity information. However, the number plates of a plurality of carrying vehicles are covered by sludge to be difficult to identify due to more sludge in the process of carrying mineral aggregates, and the number plates are maliciously shielded, so that the number plates need to be cleaned, the travelling speed of the carrying vehicles is greatly reduced in the cleaning process, and the vehicles are blocked. Meanwhile, in the process of scanning the license plate by using the OCR equipment, the vehicle needs to be scanned after being stopped stably so as to improve the accuracy of license plate recognition, and in the process of recognizing the license plate, the carrying vehicle needs to be stopped and restarted, so that the traveling speed of the vehicle is greatly reduced, and the condition of vehicle blockage is easy to occur. To solve this problem, in a further embodiment, the first identifier 15, the second identifier 23, and the third identifier 41 each employ an RFID (Radio frequency identification) reader. In order to facilitate the identification of the RFID reader, each carrier vehicle is provided with a unique RFID electronic tag so that the RFID electronic tag is matched with information such as a license plate of the carrier vehicle, and the matching information is stored in the storage unit. The RFID technology is a technology for carrying out contactless automatic identification by utilizing a wireless radio frequency mode, and the basic principle is to realize automatic identification on an object to be identified in a static state or a moving state by utilizing a radio frequency signal. When the carrying vehicle passes by, the RFID reader identifies the RFID electronic tags, and each vehicle is provided with the unique RFID electronic tag, so that the identification information of the transport vehicle is known. In the process, the carrying vehicle does not need to be stopped for identification, so that the transportation efficiency of the vehicle is improved.
Due to the supervision difficulty, the situation that the evidence is difficult to obtain and the situation that the mineral aggregate is difficult to correct is common in the process of carrying the mineral aggregate by a vehicle at present. How to solve the problem becomes a problem which needs to be solved urgently. To address this issue, in a further embodiment, the monitoring system further comprises a human-machine interaction module. The man-machine interaction module comprises a plurality of camera devices, an alarm device and a display screen. Wherein, the camera device is respectively arranged at the oblique side of the loading station 12 of the ore bin 10, in the pound room 20 and in the ore material field 40. The alarm device adopts a buzzer which is arranged on the wall of the side surface of the ore bin 10, the wall of the weight house 20 and the mineral aggregate field 40. The display screen is arranged in the main control room 30 of the monitoring system, when the carrier vehicle executes the violation business, the business module analyzes and confirms the violation state of the carrier vehicle and issues an early warning instruction by adopting a display capable of displaying in a split screen mode, and the camera device shoots and obtains evidence and displays the evidence through the display screen, so that later-stage responsibility tracing is facilitated; meanwhile, the buzzer alarms and buzzes to remind vehicles of illegal execution services, and the illegal execution services are reminded and corrected in time, so that the advance correction is realized, the post-processing is reduced, and the quick processing of the illegal execution services is realized. Meanwhile, the arrangement also promotes the visualization of the system and the human-computer interaction of the system.
During the loading of mineral material, it often happens that a plurality of carrier vehicles enter the ore bin 10 to be loaded together with the vehicle, and the main reasons for this are: 1. the waiting time is reduced, and the loading and carrying speed of the mineral aggregate is improved; 2. the malicious car tracking causes the recognition device to be difficult to recognize, so that the unidentified car steals the mineral aggregate. In the prior art, a shooting device is usually adopted for shooting in real time and a manager performs background observation, so that certain labor cost is required to be invested, and meanwhile, the shooting device does not have the function of identifying illegal services and needs the manager to perform real-time monitoring, so that the labor intensity of the manager is greatly increased. To address this issue, in a further embodiment, the monitoring system further comprises an automatic lift gate 50 and a third infrared detector 51. Referring to fig. 2, the automatic lifting door 50 is disposed at an entrance of the access passage 11, the third infrared detector 51 is also disposed at the entrance of the access passage 11, a transmitting end and a receiving end of the third infrared detector 51 are respectively disposed at two sides of the entrance of the access passage 11, and a vehicle that needs to enter the access passage 11 is monitored, the operating principle of the third infrared detector 51 is similar to that of the first infrared detector 14 and the second infrared detector 22, and when the receiving end cannot receive infrared rays transmitted by the transmitting end, it is determined that the vehicle to be charged waits; after the vehicles on the charging station 12 are completely charged, the automatic lifting door 50 is opened, so that the vehicles waiting at the inlet of the access passage 11 enter the ore bin 10 one by one for charging. However, in the actual operation process, in order to prevent a person from intentionally blocking the infrared ray emitted from the emission end of the third infrared detector 51, the monitoring system may make a false judgment. The monitoring system further comprises a gravity sensor 52, which gravity sensor 52 is provided below the ground at the entrance to the access shaft 11. When a vehicle to be loaded is waiting, the pressure of the vehicle against the ground is transmitted to the gravity sensor 52 and detected by the gravity sensor 52. The automatic lifting door 50 is arranged to isolate the vehicle which is loading from the vehicle waiting for loading, so that a plurality of vehicles are prevented from entering the loading station 12 with the vehicle, and the vehicle waiting for loading is ensured to wait at the entering channel 11 when the loading vehicle loads; the loading vehicle leaves the loading station 12 after loading is finished, the third infrared detector 51 detects the position of the vehicle to be loaded, the gravity sensor 52 detects the pressure of the vehicle to be loaded, the automatic lifting door 50 is opened after finishing the confirmation, the vehicle to be loaded enters the loading station 12 for loading, the third infrared detector and the gravity sensor 52 perform double detection on the vehicle to be loaded, and the situation that the third infrared detector 51 is blocked maliciously or the gravity sensor 52 is pressurized to force the automatic lifting door 50 to be opened is avoided.
During the process of carrying the mineral aggregate, the carrying efficiency of the carrying vehicle is extremely important, and if the carrying efficiency of the carrying vehicle is low, the mineral aggregate in the mineral silo 10 is accumulated in a large amount, and the risk of the expansion of the mineral silo 10 is easily caused. Therefore, it is important how to reduce the risk of bin expansion of the bin 10. To address this issue, in a further embodiment, the monitoring system further comprises a pull bin module. It should be noted that the process of pulling the bin refers to a process of pulling the discharge hole at the bottom of the ore bin 10 for discharging when the ore bin 10 expands. The bin pulling module in this embodiment includes a second control switch for controlling the ore bin 10 to discharge, and the second control switch is connected in parallel with the first control switch. When the ore bin 10 has the risk of bin expansion, the discharging time of the ore bin 10 is prolonged through the bin pulling module, and the loading capacity of a carrying vehicle is improved, so that the bin expansion of the ore bin 10 is avoided. The specific process is that when the carrying vehicle carries out charging, the first control switch is closed, the discharge hole at the bottom of the ore bin 10 is opened and discharges materials according to the set discharging time, and then the first control switch is disconnected to close the discharge hole at the bottom of the ore bin 10 and stop discharging; when the risk of expanding the storehouse, when first control switch disconnection, second control switch closed connection because first control switch and second control switch are parallelly connected for the drain hole of ore deposit 10 bottom keeps opening and lasts the blowing volume, thereby prolongs the blowing time of ore deposit 10. After the material transferring amount of the carrying vehicle is increased, the carrying vehicle is easy to bear overweight, after the carrying vehicle passes through the weighing wagon balance 21 of the weight room 20 for weighing, the overweight carrying vehicle enters the weight room 20 again for weighing after unloading in a waste material place, and the overweight carrying vehicle is timely shipped.
The working principle is as follows: with reference to fig. 5 and 6, when the intelligent monitoring system for mineral aggregate carried by a vehicle provided by the present application is used to monitor the carrying condition of the vehicle, firstly, the identity information (including license plate information, driver information, etc.) of the carrying vehicle, the carrying vehicle load limit M, and the emptying time T of the ore bin 10 need to be input through the input unit of the host module.
