[0072] The real-time capacity of the plant area refers to: at this time, the ratio of the number of coal-carrying vehicles accommodated in a certain designated area within the plant (thermal power plant) to the maximum capacity standard number in the designated area.

[0073] In a specific implementation of this embodiment, two partition positions are pre-demarcated in the factory area, and accordingly, the partition entrance monitoring components 4 are provided at the partition entrances of the two partition positions.

[0085] The first broadcast unit 24 , the first license plate recognizer 21 , the factory entry gate 22 , and the in-factory vehicle storage total display unit 23 are all electrically connected to the intelligent control terminal 1 .

[0086] In the present invention, by providing the in-plant vehicle total display unit 23 and the first broadcast unit 24, information guidance is provided to the driver, so that the driver can perform standardized operations.

[0087] In a specific implementation of this embodiment, every time a vehicle enters the factory through the entry gate 22, the number of vehicles entering the factory is accumulated by one; every time a vehicle leaves the factory through the exit gate (not shown in the figure), the number of vehicles leaving the factory is accumulated by one; the real-time number of vehicles in the factory is the difference between the number of vehicles entering the factory and the number of vehicles leaving the factory.

[0088] In a specific implementation of this embodiment, the entry gate 22 and the exit gate respectively record the number of vehicles entering the plant and the number of vehicles leaving the plant, that is, the entrance and exit of the thermal power plant are different road entrances.

[0089] In another specific implementation of this embodiment, the exit gate and the entry gate 22 are the same component, that is, the inlet of the thermal power plant is also the outlet.

[0090] The intelligent control terminal 1 periodically checks and updates the real-time vehicle capacity within the plant and the real-time capacity within the plant according to the position information of the coal transport vehicle detected by the vehicle position identification component 3 .

[0093] When it is determined that the vehicle to be entered into the factory is an external vehicle, the intelligent control terminal 1 sends a first warning reminder instruction (which is information to be broadcast or carries information to be broadcast) to the factory entrance monitoring component 2. The total display unit 23 for accommodating vehicles in the factory and the first broadcast unit 24 display and broadcast according to the first warning instruction, for example: display and broadcast the sentence, "You are an unregistered vehicle and are temporarily prohibited from entering the factory. Please verify the registration information. Thank you."

[0094] In a specific implementation of this embodiment, after determining that the vehicle to be admitted into the plant is a coal transport vehicle, the real-time capacity of the plant is also detected;

[0095] When it is detected that the real-time capacity of the factory is lower than the (preset) maximum capacity standard of the factory, the intelligent control terminal 1 sends a first control instruction to the factory entrance monitoring component 2 to control the factory entrance gate 22 to open;

[0096] When it is detected that the real-time capacity of the factory is equal to or higher than the (preset) maximum capacity standard of the factory, the intelligent control terminal 1 sends a third warning reminder instruction (which is information to be broadcast or carries information to be broadcast) to the factory entrance monitoring component 2, and the total display unit 23 of the vehicles accommodated in the factory and the first broadcast unit 24 display and broadcast according to the third warning instruction, for example: display and broadcast the sentence "There are many vehicles in the factory, please wait for a while."

[0097] In a specific implementation of this embodiment, the (preset) maximum capacity standard within the factory is a capacity standard for maintaining stable two-way movement of vehicles within the factory without interfering with each other. In principle, it is much smaller than the capacity for stationary vehicles within the factory.

[0098] It should be noted that the electrical connection described in this embodiment refers to: a network cable connection, a network connection, or a combination of the two to achieve information transmission.

[0099] Please refer to the attached Figure 1 In a specific implementation of this embodiment, the vehicle position identification component 3 includes:

[0103] It should be pointed out that the location information of the coal transport vehicles includes: the location information of all coal transport vehicles in the plant area (or within the plant area), that is: the number of coal transport vehicles is also reflected in the data information.

[0104] In a specific implementation of this embodiment, the on-board electronic tag 31 stores the unique identification information of the coal transport vehicle, such as license plate information, vehicle model, vehicle data information (model, size, load, etc.), etc.

[0105] In a specific implementation of this embodiment, the vehicle-mounted electronic tag 31 continuously sends a radio signal of a specific frequency to the surroundings, and the identification base station 32 receives the radio signal at the frequency, or,

[0106] The identification base station 32 continuously sends an excitation signal to the surroundings. After receiving the excitation signal, the vehicle-mounted electronic tag 31 sends a radio signal of a specific frequency, and the signal base station 32 receives the radio signal at the frequency.

[0107] There are multiple identification base stations 32. When multiple identification base stations 32 receive the radio signal sent by the vehicle-mounted electronic tag 31 (of one of the coal transport vehicles), they use triangulation or other positioning algorithms to calculate and determine the location information of the coal transport vehicle.

[0108] Specifically, the vehicle position identification component 3 also includes: a position information processing unit (not shown in the figure), which determines the position relationship of the coal transport vehicle relative to each base station based on parameters such as the time difference and signal strength of the signals received by different identification base stations 32, and then obtains the position information (coordinate information) of the coal transport vehicle through mathematical calculation.

[0113] In another specific implementation of this embodiment, after the vehicle to be transported into the factory is determined to be a coal transport vehicle, it is checked whether the coal transport vehicle is affixed with the vehicle-mounted electronic tag 31;

[0114] If it is detected that there is no on-board electronic tag 31 affixed to the coal transport vehicle, the on-board electronic tag 31 will be affixed to the coal transport vehicle when or after the coal transport vehicle enters the factory (this is not limited to manual affixment or mechanical affixment).

[0115] In a specific implementation of this embodiment, a plurality of identification base stations 32 are arranged on the sides of the factory roads and / or sub-district roads, and the interval distance between any two adjacent identification base stations 32 of the plurality of identification base stations 32 is equal.

[0134] When it is determined that the coal-carrying vehicle to be entered into the zone does not have the authority to enter the designated area, the intelligent control terminal 1 sends a second warning reminder instruction (which is information to be broadcast or carries information to be broadcast) to the partition entrance monitoring component 4. The vehicle display unit 43 and the second broadcast unit 44 in the zone accommodate vehicles, and display and broadcast according to the second warning instruction, for example: display and broadcast the sentence, "You are an unauthorized vehicle and are temporarily prohibited from entering the zone.
