Description

Technical Field

[0001] The present invention relates to the technical field of coal mine vehicle charging, and more specifically to an intelligent charging and discharging Internet of Things cloud integrated platform. Background Art

[0002] Electric coal mining vehicles are now used in existing mines or coal mining areas. By building multiple charging areas, the cost of vehicle power energy can be effectively saved. Compared with oil vehicles, the economic benefits are higher. However, electric coal mining vehicles need to be charged after the battery is low, which takes a long time. When you want to charge the vehicle, you cannot directly find a charging location, which takes a long time and delays the efficiency of the operation.

[0003] Therefore, it is necessary to propose an intelligent charging and discharging IoT cloud integrated platform to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problems mentioned in the background technology.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] An intelligent charging and discharging Internet of Things cloud integrated platform, comprising a vehicle machine module that is communicatively connected to a cloud processing module and installed on an electric coal mining vehicle, a plurality of charging modules arranged in a mining area, and a vehicle owner's mobile phone terminal;

[0007] The vehicle module includes:

[0008] The pressure monitoring module is used to monitor whether the coal mine car is empty or loaded. When the coal mine car is loaded, the weight of the load needs to be calculated;

[0009] The power monitoring module is used to monitor the mileage that the coal mine car can travel with the remaining power when it is unloaded and loaded. The monitoring is based on the current state of the coal mine car. When the coal mine car is now in an unloaded state, the remaining power is calculated based on the mileage that the coal mine car can travel with the remaining power in the unloaded state. Until the pressure monitoring module detects that the coal mine car is in a loaded state, the remaining power is calculated based on the mileage that the coal mine car can travel with the remaining power in the loaded state, and the mileage of the same model of coal mine cars under different load weights is recorded;

[0010] Voice reminder module, when the remaining power reaches a certain limit, is used to remind the owner of the remaining mileage that can be traveled, and remind the owner to navigate to the nearest location where the charging unit can be quickly connected;

[0011] Coal mine car unlocking module, used to enter a random password to unlock the coal mine car;

[0012] Charging module, each charging module includes multiple charging units, each charging unit has a unique code, is used to charge the coal mine car, and can automatically cut off the power, issue voice and light prompts;

[0013] The charging module also includes:

[0014] A visual recognition device is used to monitor the number of coal mine cars entering the charging area and the model of the coal mine cars; by identifying the model of the coal mine car, searching for the capacity of its battery and calculating the remaining power and the time from the remaining power to full power through the power monitoring module;

[0015] A charge and discharge monitoring device is used to monitor the stored power of the coal mine car. When all charging units are charging, the visual recognition device monitors the charging unit of the coal mine car with the highest power when the next coal mine car arrives at the charging module. The position of the charging unit is a position where the charging unit can be quickly connected.

[0016] The limiting module is used to limit the position of the coal mine car when it reaches the position where the charging unit can be quickly connected. The position is on the road corresponding to the charging unit adjacent to the charging unit of the coal mine car with the highest power storage and facing the side of the charging module entrance. When all the charging units are charging, the limiting module receives the position of the charging unit that can be quickly connected monitored by the charge and discharge monitoring device to prevent the coal mine car from blocking the pick-up path of the coal mine car with the highest power storage;

[0017] The cloud processing modules include:

[0018] A route planning module is used to plan a route and display it on the vehicle computer module according to the vehicle owner's selection of the prompt content of the voice reminder module;

[0019] A password distribution module is used to distribute a password to the owner of a coal mine car that is being charged. When the visual recognition device detects a coal mine car that has navigated to the nearest location where the charging unit can be quickly connected, the password distribution module distributes a mobile password to the owner of the coal mine car to unlock the corresponding coal mine car. At this time, the charging unit automatically powers off and issues a voice and light prompt.

[0020] The mobile terminal is used to receive the password assigned by the password assignment module for the vehicle owner to memorize, and the assigned password is used to enter the corresponding coal mine vehicle unlocking module to start the coal mine vehicle;

[0021] The password lasts until the coal mine car is connected to the charging unit for charging next time and the visual recognition device detects that the mobile terminal or the coal mine car driven by the mobile terminal leaves the charging module.

[0022] Furthermore, the calculation of the limits of the two states is divided into:

[0023] When unloaded, the remaining power must be sufficient to cover the distance from the current position of the coal mine vehicle to the position where the charging unit can be quickly connected;

[0024] When in load state, the remaining power must meet the mileage from the current position of the coal mine car to the unloading position, and from the unloading position to the position where the charging unit can be quickly connected.

[0025] Furthermore, the priority of the position where the charging unit can be quickly connected is:

[0026] First priority: There is an idle charging unit and the charging module to which the charging unit belongs has a coal mine car of the same model, and the charging storage capacity of the coal mine car is within 80-100% and is the highest;

[0027] Second priority: There are no idle charging units, and the charging module to which the charging unit belongs has a coal mine car of the same model being charged, and the charging storage capacity of the coal mine car is within 80-100% and is the highest;

[0028] The third priority: there are idle charging units and the charging module to which the charging unit belongs has coal mine cars of different models, and the charging storage capacity of the coal mine car is within 80-100% and is the highest;

[0029] Fourth priority: There are no idle charging units, and there are coal mine cars of different models being charged in the charging module to which the charging unit belongs, and the charging storage capacity of the coal mine cars is within 80-100% and is the highest.

[0030] Furthermore, the reminder rule is: when there is an idle charging unit and the coal mine car has a certain remaining power limit, the vehicle computer module of the coal mine car owner closest to the specific location is given priority.

[0031] Furthermore, the charging module includes two rows of charging units arranged side by side, and a two-way road is provided between the two rows of charging units.

[0032] Furthermore, the positioning module includes a drone provided with a parking sign, the parking sign is provided under the drone, and the positioning method of the drone is as follows:

[0033] The charging units are arranged in sequence with the center of the road corresponding to each charging unit as the base point. The drone moves in a straight line along the base point, and falls vertically after moving to the corresponding base point, so that the parking sign is close to the ground or a certain distance from the ground.

[0034] Furthermore, the limiting module includes an N-shaped frame fixed at both ends of the road, a mounting rod fixedly connected to the two corners of the upper end of the N-shaped frame, a threaded shaft rotatably connected to the middle part of the upper end of the N-shaped frame, a connecting plate slidably connected to the mounting rod, a motor fixedly connected to the N-shaped frame, an electric push rod fixedly connected to the lower end of the connecting plate, and a parking sign fixedly connected to the lower end of the electric push rod, the output shaft of the motor is fixedly connected to the end of the threaded shaft, and the middle part of the connecting plate is threadedly connected to the outer side surface of the threaded shaft.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] See also Figure 1-3, an intelligent charging and discharging IoT cloud integrated platform, including a vehicle module that is connected to a cloud processing module and installed on an electric coal mine vehicle, multiple charging modules set up in a mining area, and a mobile phone terminal of a vehicle owner. The electric coal mine vehicle is started by a password.

[0045] The vehicle module includes:

[0046] The pressure monitoring module is used to monitor whether the coal mine car is unloaded or loaded. The future mileage is different in the two states. When the coal mine car is loaded, the weight of the load needs to be calculated, so that the power loss can be calculated more accurately, and the mileage that can be traveled by the power can also be calculated by monitoring a certain amount of parameters. The service life of the power and the curve coefficient of the power loss can also be obtained;

[0047] The power monitoring module is used to monitor the mileage that the coal mine car can travel with the remaining power under no-load and load conditions. The monitoring is performed based on the current state of the coal mine car. When the coal mine car is now in an no-load state, the remaining power is calculated based on the mileage that the coal mine car can travel with the remaining power under the no-load state. Until the pressure monitoring module detects that the coal mine car is in a loaded state, the remaining power is calculated based on the mileage that the coal mine car can travel with the remaining power under the loaded state. The batteries of different models of vehicles are different, and the load capacity is also different. Therefore, it is necessary to record the mileage of the same model of coal mine car under different load weights for separate monitoring;

[0048] The voice reminder module is used to remind the owner of the remaining mileage when the remaining power reaches a certain limit, and remind the owner to navigate to the nearest location where the charging unit can be quickly connected. After receiving the user's feedback, the signal is sent to the cloud processing module, and the cloud processing module sends the corresponding command to the vehicle module;

[0049] Specifically, the reminder rule is: when there is an idle charging unit and the coal mine car has a certain remaining power limit, the vehicle computer module of the coal mine car owner closest to the location will be reminded first.

[0050] The calculation of the limits of the two states is divided into:

[0051] When unloaded, the remaining power must be sufficient to cover the distance from the current position of the coal mine vehicle to the position where the charging unit can be quickly connected;

[0052] When in load state, the remaining power must meet the mileage from the current position of the coal mine car to the unloading position, and from the unloading position to the position where the charging unit can be quickly connected.

[0053] The priority of locations where charging units can be quickly connected is:

[0054] First priority: There is an idle charging unit and the charging module to which the charging unit belongs has a coal mine car of the same model, and the charging storage capacity of the coal mine car is within 80-100% and is the highest;

[0055] Second priority: There are no idle charging units, and the charging module to which the charging unit belongs has a coal mine car of the same model being charged, and the charging storage capacity of the coal mine car is within 80-100% and is the highest;

[0056] The above can satisfy the requirement that the vehicle directly drives into the charging unit for charging.

[0057] The third priority: there are idle charging units and the charging module to which the charging unit belongs has coal mine cars of different models, and the charging storage capacity of the coal mine car is within 80-100% and is the highest;

[0058] Fourth priority: There are no idle charging units, and there are coal mine cars of different models being charged in the charging module to which the charging unit belongs, and the charging storage capacity of the coal mine cars is within 80-100% and is the highest.

[0059] The above can meet the needs of quickly finding a vehicle that can be put into work and work for a longer period of time, thereby improving work efficiency.

[0060] Coal mine car unlocking module, used to enter a random password to unlock the coal mine car;

[0061] The charging module is equivalent to the charging area. Each charging module includes multiple charging units. Each charging unit has a unique code and is used to charge the coal mine vehicle. The owner needs to plug and unplug the charging cable by himself, but the charging unit can automatically power off, issue voice and light prompts. In the future, the charging cable can also be plugged and unplugged by setting up an automatic plug-in robot;

[0062] The charging module also includes:

[0063] The visual recognition device is used to monitor the number of coal mine cars entering the charging area and the type of coal mine cars, so as to monitor the carrying capacity of the charging module and the number of vehicles waiting to be charged, so as to avoid too many vehicles that need to be charged from rushing into the charging module at the same time and blocking the normal road travel of the charging module; by identifying the type of coal mine car, searching for the capacity of its battery and calculating the remaining power and the time from the remaining power to full power through the power monitoring module;

[0064] A charge and discharge monitoring device is used to monitor the stored power of the coal mine car. When all charging units are charging, the visual recognition device monitors the charging unit of the coal mine car with the highest power when the next coal mine car arrives at the charging module. The position of the charging unit is a position where the charging unit can be quickly connected.

[0065] The limit module is used to limit the position of the coal mine car when it reaches the position where the charging unit can be quickly connected, so as to prevent the coal mine car that needs to be charged from blocking the charged coal mine car that needs to be replaced. In this way, it is more convenient for the car owner to replace the vehicle. He only needs to drive the charged coal mine car out first, then drive the coal mine car that needs to be charged in, and then drive the charged coal mine car away. The position is adjacent to the charging unit of the coal mine car with the highest power storage and on the road corresponding to the charging unit on the side facing the charging module entrance. When all the charging units are charging, the limit module receives the position of the charging unit that can be quickly connected monitored by the charge and discharge monitoring device, so as to prevent the coal mine car from blocking the pick-up path of the coal mine car with the highest power storage;

[0066] The cloud processing modules include:

[0067] A route planning module is used to plan a route and display it on the vehicle computer module according to the vehicle owner's selection of the prompt content of the voice reminder module;

[0068] The password allocation module is used to allocate a password to the owner of the coal mine car that is coming to charge. When the visual recognition device detects the coal mine car that has navigated to the nearest location where the charging unit can be quickly connected, the password allocation module allocates a mobile password to the owner of the coal mine car. The password format is composed of the encoding of the charging pile plus a random password, which is convenient for quickly seeing the location of the charged vehicle and is used to unlock the corresponding coal mine car. At this time, the charging unit will also automatically cut off the power and issue a voice and light prompt to further remind the owner;

[0069] The mobile terminal is used to receive the password assigned by the password assignment module for the vehicle owner to memorize. The assigned password is used to enter the corresponding coal mine vehicle unlocking module, and the coal mine vehicle can be started after unlocking;

[0070] The password lasts until the coal mine car is connected to the charging unit for charging next time and the visual recognition device detects that the mobile terminal or the coal mine car driven by the mobile terminal leaves the charging module.

[0071] Specifically, the charging module includes two rows of charging units arranged side by side, and a two-way road is provided between the two rows of charging units. Under this, a variety of limiting modes of limit modules can be set, for example:

[0072] like Figure 1 As shown, the limiting module includes a drone equipped with a parking sign, and the parking sign is set under the drone. The positioning method of the drone is as follows: the drones are arranged in sequence with the center of the road corresponding to each charging unit as the base point, and the drone moves along the base point straight line, and falls vertically after moving to the corresponding base point, so that the parking sign is close to the ground or a certain distance from the ground.

[0073] Or use this method: Combine Figure 2As shown, some structural parts are needed for installation, wherein the limit module includes an n-shaped frame 1 fixed at both ends of the road, a mounting rod 2 fixedly connected to the two corners of the upper end of the n-shaped frame 1, a threaded shaft 3 rotatably connected to the middle part of the upper end of the n-shaped frame 1, a connecting plate 5 slidably connected to the mounting rod 2, a motor 4 fixedly connected to the n-shaped frame 1, an electric push rod 6 fixedly connected to the lower end of the connecting plate 5, and a parking sign fixedly connected to the lower end of the electric push rod 6, wherein the output shaft of the motor 4 is fixedly connected to the end of the threaded shaft 3, and the middle part of the connecting plate 5 is threadedly connected to the outer side surface of the threaded shaft 3, wherein the motor 4 drives the threaded shaft 3 to rotate, thereby driving the connecting plate 5 to move, thereby driving the parking sign to move, and after moving to the position, the electric push rod 6 is controlled to extend, thereby driving the parking sign to move downward.

[0074] Specific, combined Figure 3 As shown, in order to enhance the stability and anti-deformation ability of the mounting rod 2, an avoidance opening 7 is opened at the lower end of the connecting plate 5 located at the lower end of the mounting rod 2, and the lower end of the mounting rod 2 located in the avoidance opening 7 is fixedly connected to a support rod 8, and the support rod 8 is fixed on both sides of the road and avoids the position of the charging unit so as not to affect the vehicle's entry and exit.

[0075] Both of the above methods can realize the parking requirement for vehicles that need to be charged, and can be freely selected during implementation. In addition, the parking sign uses an electronic display screen, which can display not only "Please stop" but also some steps to guide car owners to change vehicles.

[0076] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the contents of the description and drawings of the present invention should also be included in the protection scope of the present invention.
