Description

Technical Field

[0001] The present invention belongs to the technical field of coal supply and marketing, and relates to vehicle satellite positioning, rapid coal quality analysis, rapid coal dehydration, automatic control systems and intelligent management and control systems, and specifically relates to an intelligent management and control system for outgoing coal and a preparation method thereof. Background Art

[0002] As an important part of my country's energy structure, coal not only provides indispensable support for the daily production and life of Chinese people, but also makes great contributions to my country's metallurgy, power generation, chemical industry and national defense. However, coal resources are non-renewable resources. How to efficiently utilize coal resources is an urgent problem to be solved. Intelligent management and control of the entire process of coal production, selection, supply and sales is also the direction of future development. At present, when coal is sold or supplied in coal mines or coal preparation plants, it is impossible to quickly and accurately calibrate the coal industry analysis indicators when the coal leaves the factory, and the coal trucks cannot be reasonably and effectively controlled after leaving the factory. Sometimes, it will cause the lawless elements to add water to the coal during the transportation process to increase the weight of the transported coal, or even replace the original coal with inferior coal. In serious cases, it will cause the risk of coal-fired boiler shutdown of the coal-using unit, damage the economic benefits of the coal-using enterprise, and bring unnecessary economic losses and disputes to the coal-supplying enterprise, and damage the reputation of the coal-supplying enterprise.

[0003] At present, it is very difficult to take samples and conduct tests on every coal truck when it leaves the factory. Although the industrial indicators of the same batch of coal leaving the factory should be similar for coal mines or coal preparation plants, it is still a pain point for coal supply units to be unable to issue a coal quality inspection report for a single coal truck when faced with disputes. In addition, at present, the coal quality testing process is highly dependent on manual operation, and the testing process also has disadvantages such as poor timeliness and human interference. Summary of the invention

[0004] The purpose of the present invention is to address the defects and shortcomings of the above-mentioned prior art, and propose an intelligent management and control system for outgoing coal and its preparation method. By integrating the vehicle satellite positioning system, the vehicle operation status can be fed back in real time, the vehicle driving route can be preset, and when the vehicle does not drive according to the prescribed route or the vehicle stops in a non-rest area for too long, an early warning can be automatically triggered, the vehicle is marked, and the early warning information is sent to the management personnel, the vehicle driver, and the coal user unit, and the coal user unit cooperates with the coal user unit to prevent abnormal behavior during coal transportation. The present invention introduces microwave dehydration equipment in the coal sample preparation link, which can quickly dehydrate the coal sample and calibrate the total water index of the coal sample in the process; in terms of coal quality analysis, the laser coal quality analysis method is cited, and a major breakthrough has been made in the field of coal quality analysis. The laser coal quality analysis method only needs to use a high-energy laser to irradiate and scan the coal sample ground into 0.2 mm to obtain the industrial analysis index of the sample, which greatly improves the efficiency of coal quality analysis. .

[0005] The technical solution adopted by the present invention to solve the technical problem is: an intelligent control system for outgoing coal, the system comprising a lane gate management unit, a vehicle guidance unit, a weighing unit, a vehicle automatic sampling unit, a coal sample transport belt unit and a vehicle satellite positioning unit;

[0006] The lane gate management unit is used for license plate recognition, vehicle type recognition, and driver face recognition;

[0007] The vehicle guidance unit is used to dispatch and guide vehicles, and the road vehicle guidance lights regulate the vehicle driving lanes and guide vehicles to travel in an orderly manner in harsh environments;

[0008] The weighing unit of the scale is used to feed back the vehicle weight in real time and upload it to the management system for matching with the license plate;

[0009] The fully automatic sampling unit for the vehicle is used for random three-point sampling in the cargo box of the coal vehicle;

[0010] The coal sample transport belt unit is used to transport the coal sample to various devices or systems;

[0011] The vehicle satellite positioning unit is used to monitor the vehicle's driving route and driving conditions in real time, and trigger an early warning signal when the vehicle deviates from the preset route or stops abnormally for a long time.

[0012] Furthermore, the lane gate management unit includes a lane gate, related supporting gantries and cameras, so as to identify and record the coal car license plate and driver information, so as to achieve a one-to-one correspondence between the coal car and the driver.

[0013] Furthermore, the vehicle guidance system includes an outdoor loudspeaker, an LED screen and road vehicle guidance lights to provide voice guidance to the coal trucks. An LED screen is placed in the vehicle waiting area to display the license plate numbers of vehicles that can be released in real time on the screen, which complements the voice guidance.

[0014] The present invention also proposes a method for preparing factory coal, which comprises the following steps:

[0015] Step 1: Randomly sample three points in the coal car bed;

[0016] Step 2: The samples are automatically transferred to the mixer via a belt conveyor, and then transferred to the hammer primary crusher to crush the samples into 6 mm;

[0017] Step 3: Use microwave dehydration equipment in conjunction with the fully automatic sampling system to quickly dry the shrunken coal sample, obtain the total moisture data of the coal sample, prepare the coal sample into a dry basis coal sample, and transport it back to the sample preparation system;

[0018] Step 4: Perform subsequent grinding operation on the coal sample to make the received base coal sample into a general analytical experimental coal sample of 0.2 mm;

[0019] Step 5: Analyze the spectrum through a laser coal quality analyzer to map out the industrial analysis indicators of the coal.

[0020] Furthermore, step 3 includes: packaging the coal samples to be stored through the sample intelligent storage and checking equipment, attaching RFID tags to the sample bags after packaging, saving vehicle information and time information, and then randomly placing the sample bags on the sample storage racks. When needed in the future, the required coal samples can be automatically extracted by entering the license plate number and the storage time. The automatic sample storage equipment has a built-in automatic sample discarding function, and the coal sample expiration time can be set as needed, and the expired coal samples can be automatically discarded to the discarded sample recovery area.

[0021] Furthermore, step 5 includes: the laser coal quality analyzer has a built-in laser, which irradiates the sample surface with high-energy laser rays to make the atoms in the coal sample react, and uses a detector to collect spectral information reflected by the sample. Since the reflection spectra of atoms of different elements are different, the spectrum is analyzed, and the types and contents of all elements in the sample are calibrated at the same time, and brought into the mathematical model for analysis.

[0022] Beneficial effects:

[0023] 1. The development of an intelligent control system for factory coal in the present invention is an integration and cross-fusion of multiple systems, and a breakthrough in the field of coal supply and marketing control. In order to achieve intelligent control of the coal quality and coal vehicles of the factory coal, the vehicle satellite positioning system is integrated to provide real-time feedback on the vehicle operation status and preset the vehicle driving route. When the vehicle does not travel along the prescribed route or the vehicle stops in a non-rest area for too long, an early warning can be automatically triggered, the vehicle will be marked, and early warning information will be sent to management personnel, vehicle drivers, and coal-using units, so as to cooperate with the coal-using units to prevent abnormal behavior in the coal transportation process.

[0024] 2. The present invention introduces microwave dehydration equipment in the coal sample preparation process, which can quickly dehydrate the coal sample and calibrate the total water index of the coal sample in the process; in terms of coal quality analysis, the laser coal quality analysis method is used, which has made a major breakthrough in the field of coal quality analysis. The laser coal quality analysis method only needs to grind the coal sample into 0.2mm and use a high-energy laser to irradiate and scan it to obtain the industrial analysis index of the sample, which greatly improves the efficiency of coal quality analysis.

[0025] 3. In terms of the process, the present invention adopts unmanned fully automatic control throughout the process, which is more efficient and reliable. The application of this system can implement control and early warning of coal trucks leaving the factory, and can quickly generate a separate coal quality report for each coal truck leaving the factory. After the coal truck leaves the factory after sampling, it can receive the coal quality report within 20 minutes, which greatly improves efficiency and reduces the possibility of disputes between coal-using enterprises, coal-supplying enterprises, and transportation drivers. At the same time, it can also efficiently control the coal transportation process, which is a major breakthrough in the coal production, supply, and sales industry chain.

[0027] Figure 2 The present invention is a flow chart of a method for preparing coal for factory delivery. DETAILED DESCRIPTION

[0028] The invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1 As shown, the present invention proposes an intelligent control system for outgoing coal, which specifically includes a lane gate management unit, a vehicle guidance unit, a weighing unit, a vehicle automatic sampling unit, a coal sample transfer belt unit and a vehicle satellite positioning unit, wherein:

[0030] The lane gate management unit is used for license plate recognition, vehicle type recognition, and driver face recognition. It includes a lane gate, related supporting gantry, and camera to identify and record the coal truck license plate and driver information, so that the coal truck and driver are one-to-one corresponding.

[0031] The vehicle guidance unit is used to dispatch and guide vehicles. The road vehicle guidance lights regulate the vehicle driving lanes and guide vehicles to drive in an orderly manner in harsh environments. It includes outdoor loudspeakers, LED screens and road vehicle guidance lights. It provides voice guidance to coal cars. An LED screen is placed in the vehicle waiting area to display the license plate numbers that can be released on the screen in real time, which complements the voice guidance.

[0032] The weighing unit of the scale is used to feed back the vehicle weight in real time and upload it to the management system to match it with the license plate;

[0033] The fully automatic sampling unit of the car is used to carry out random three-point sampling in the coal car bed;

[0034] The coal sample transfer belt unit is used to transfer the coal sample to various equipment or systems;

[0035] The vehicle satellite positioning unit is used to monitor the vehicle's route and driving conditions in real time, and trigger a warning signal when the vehicle deviates from the preset route or stops abnormally for a long time.

[0036] The present invention also proposes a method for preparing coal for delivery, which specifically comprises the following steps:

[0037] Step 1: Randomly sample three points in the coal car bed;

[0038] Step 2: The samples are automatically transferred to the mixer via a belt conveyor, and then transferred to the hammer primary crusher to crush the samples into 6 mm;

[0039] Step 3: Use microwave dehydration equipment in conjunction with the fully automatic sampling system to quickly dry the shrunken coal sample, obtain the total moisture data of the coal sample, prepare the coal sample into a dry basis coal sample, and transport it back to the sample preparation system;

[0040] Step 4: Perform subsequent grinding operation on the coal sample to make the received base coal sample into a general analytical experimental coal sample of 0.2 mm;

[0041] Step 5: Analyze the spectrum through a laser coal quality analyzer to map out the industrial analysis indicators of the coal.

[0042] The above step 3 of the present invention includes: packaging the coal samples to be stored through the sample intelligent storage and inspection equipment, attaching RFID tags to the sample bags after packaging, saving vehicle information and time information, and then randomly placing the sample bags on the sample storage racks. When needed in the future, the required coal samples can be automatically extracted by inputting the license plate number and the storage time. The automatic sample storage equipment has a built-in automatic sample discarding function, and the coal sample expiration time can be set as needed, and the expired coal samples can be automatically discarded to the discarded sample recovery area.

[0043] The above step 5 of the present invention includes: the laser coal quality analyzer has a built-in laser, which irradiates the sample surface with high-energy laser rays to make the atoms in the coal sample react, and uses a detector to collect spectral information reflected by the sample. Since the reflection spectra of atoms of different elements are different, the spectrum is analyzed, and the types and contents of all elements in the sample are calibrated at the same time, and brought into the mathematical model for analysis.

[0044] Before the coal truck enters the coal bunker for loading, the vehicle guidance system will guide it to the gate. At this time, the driver needs to get off the car for facial recognition and confirmation. At the same time, the license plate recognition system automatically recognizes the license plate and the weighbridge system records the vehicle's tare weight information. The coal loading operation can then be carried out. The entire loading process is recorded by the industrial camera in the coal bunker.

[0045] After the coal loading process is completed, the coal car is guided to the factory gate by the vehicle guidance system. At this time, the weighing system records the total weight of the vehicle and subtracts the vehicle's tare weight to get the weight of the coal. Then the automobile sampling machine randomly takes samples from three points of the coal car and transfers the sampled samples to the coal sample processing unit. The coal can be mixed, initially broken, and reduced. The sample is crushed to 6mm and two 500g samples are reduced on average. One is used for sample storage and inspection, and the other is used for coal quality analysis. The remaining samples are transported to the abandoned coal bunker for abandoned material recovery.

[0046] Details for two 500g samples:

[0047] The 500g sample for storage is packaged and packed. The automatic packaging machine can mark it with an RFID tag, and then it is transferred to the sample storage cabinet and stored in a random location to avoid interference from human factors. When a dispute arises or coal quality arbitration is required, the license plate information can be entered, and the sample storage cabinet will automatically retrieve and take out the sample for coal quality testing. The stored samples can be recycled as needed.

[0048] The 500g sample used for coal quality testing is first transferred to the coal quality rapid dehydration equipment. According to the needs, infrared dehydration or microwave dehydration equipment can be selected to quickly dehydrate the coal sample, and the total moisture index of the coal sample is calibrated by recording the weight change information of the coal sample. The dehydrated dry base coal sample is then ground into powder. The general analysis experimental coal sample ground to 0.2mm is then transferred to the laser coal quality analyzer for rapid coal quality analysis. The type and content of elements contained in the coal sample are calibrated through laser spectral information. Further, the industrial analysis indicators such as ash content, calorific value, volatile matter, total sulfur, etc. of the coal sample can be obtained through mathematical models.

[0049] The coal quality analysis indicators will be issued by the coal quality control system within 20 minutes, and a coal quality report will be generated in combination with relevant information, including license plate number, vehicle model, driver information, coal type information, net weight of the coal transported, coal moisture information, coal industry analysis indicator information, coal loading time, departure time, destination and other information. The report will be sent by the system to coal truck drivers and coal-using units.

[0050] After the sampling of the coal truck is completed, it will be guided to the exit area, where the waterproof tarpaulin can be unfolded or the truck can leave the factory directly. After leaving the factory, the satellite positioning system of the corresponding coal truck can be retrieved through the coal quality control platform to monitor the coal truck's route and real-time speed, and issue warnings for illegal operations based on actual conditions. For example, if the truck fails to drive according to the prescribed route or stops continuously for more than 10 minutes in a non-rest area, the system will mark the coal truck as a warning vehicle. The system can retrieve the driver's contact information to confirm the vehicle status and send the warning information to the coal-using unit. After the vehicle arrives at the coal-using unit, sampling and coal quality testing should be carried out on the vehicle.

[0051] The specific implementation scheme described above further describes in detail the purpose, technical scheme and beneficial effects of the present invention. It should be understood that the above is only a specific implementation scheme of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the present invention should fall within the scope of protection of the present invention.
