Description

Technical Field

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

[0002] When operating in existing mines or coal mining areas, electric coal mining vehicles are now used. 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 IoT cloud integrated platform includes a vehicle-mounted module connected to a cloud processing module and mounted on an electric coal mining vehicle, multiple charging modules located in the 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 empty and loaded. The monitoring is based on the current state of the coal mine car. When the coal mine car is in an empty state, the remaining power is calculated based on the mileage that the coal mine car can travel with the remaining power when it is empty. 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 when it is loaded, and the mileage of the same model of coal mine car under different load weights is recorded;

[0010] A voice reminder module, which reminds the owner of the remaining range when the remaining battery power reaches a certain limit and reminds the owner to navigate to the nearest location where a quick charging unit can be 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 power off, issue voice and light prompts;

[0013] The charging module also includes:

[0014] A visual recognition device is used to monitor the number and model of coal mine cars entering the charging area; 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 where the charging unit can be quickly connected.

[0016] A limiting module is used to limit the position of the coal mine car when it reaches a position where a 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 charging units are charging, the limiting module receives the position of the quick-connect charging unit monitored by the charge and discharge monitoring device to prevent the coal mine car from blocking the access path of the coal mine car with the highest power storage;

[0017] The cloud processing modules include:

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

[0019] A password assignment module is used to assign 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 location closest to the charging unit for quick connection, the password assignment module assigns the owner's mobile phone password 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. 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 in an unloaded state, the remaining power must be sufficient to cover the distance from the current position of the coal mine car to a location where a 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 between 80-100% and the highest;

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

[0028] The third priority: There is an idle charging unit and the charging module to which the charging unit belongs has a coal mine car of different models, and the charging storage capacity of the coal mine car is between 80-100% and the highest;

[0029] Fourth priority: There are no idle charging units, and there are coal mining vehicles of different models being charged in the charging module to which the charging unit belongs. The charging storage capacity of the coal mining vehicles is between 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 location will be reminded first.

[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 equipped with a parking sign, the parking sign being set below the drone. The positioning method of the drone is as follows:

[0033] The parking signs 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 away 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.

[0035] Furthermore, a clearance opening is provided at the lower end of the connecting plate at the lower end of the mounting rod, and a support rod is fixedly connected to the lower end of the mounting rod in the clearance opening, and the support rod is fixed on both sides of the road.

[0036] Furthermore, the parking sign is an electronic display screen.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] The platform provided by the present invention can orderly plan the charging situation of electric coal mining vehicles when operating in the mining area, avoiding the time spent on searching for charging units, making the operation more standardized and more efficient.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts 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-mounted module connected to a cloud processing module and mounted on an electric coal mining vehicle, multiple charging modules located in the mining area, and a vehicle owner's mobile phone terminal. The electric coal mining vehicle is started using a password.

[0045] The vehicle module includes:

[0046] The pressure monitoring module is used to monitor whether the coal mine car is empty 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. This allows for more accurate calculation of power loss and the mileage that can be traveled with the power. By monitoring certain parameters, the service life of the power and the power loss curve coefficient 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 when it is empty and loaded. The monitoring is performed based on the current state of the coal mine car. When the coal mine car is in an empty state, the remaining power is calculated based on the mileage that the coal mine car can travel with the remaining power in the empty 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. 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, when the remaining battery power reaches a certain limit, is used to remind the owner of the remaining mileage and remind the owner to navigate to the nearest location where a quick charging unit can be connected. After receiving the user's feedback, the signal is sent to the cloud processing module, which then sends the corresponding instructions 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 in an unloaded state, the remaining power must be sufficient to cover the distance from the current position of the coal mine car to a location where a 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 between 80-100% and the highest;

[0055] Second priority: There are no idle charging units, and a coal mine car of the same model is charging in the charging module to which the charging unit belongs, and the coal mine car's charging storage capacity is between 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 is an idle charging unit and the charging module to which the charging unit belongs has a coal mine car of different models, and the charging storage capacity of the coal mine car is between 80-100% and the highest;

[0058] Fourth priority: There are no idle charging units, and there are coal mining vehicles of different models being charged in the charging module to which the charging unit belongs. The charging storage capacity of the coal mining vehicles is between 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 time, and the work efficiency is higher.

[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 mining 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, and the charging cable can be plugged and unplugged by setting an automatic plug-in robot later.

[0062] The charging module also includes:

[0063] The visual recognition device is used to monitor the number and model of coal mine cars entering the charging area, thereby monitoring the carrying capacity of the charging module and the number of vehicles waiting to be charged, to prevent the charging module from being blocked by too many vehicles that need to be charged at the same time. By identifying the model of the coal mine car, the capacity of its battery is searched and the remaining power and the time from the remaining power to full power are calculated 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 where the charging unit can be quickly connected.

[0065] 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, 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 entrance of the charging module. When all the charging units are charging, the limiting module receives the position of the quick-connectable charging unit 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;

[0066] The cloud processing modules include:

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

[0068] The password assignment module is used to assign a password to the owner of a coal mine car that comes to charge. When the visual recognition device detects that the coal mine car has navigated to the location closest to the charging unit where it can quickly connect, the password assignment module assigns the owner of the coal mine car a mobile password. The password format uses the charging pile code plus a random password, which makes it easy to quickly see the location of the charged vehicle and use it to unlock the corresponding coal mine car. At this time, the charging unit will also automatically power off 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 car unlocking module, and the coal mine car 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 set between the two rows of charging units. Under this, various limiting modes can be set by setting a limit module, for example:

[0072] like Figure 1 As shown, the limiting module includes a drone equipped with a parking sign, which is set under the drone. The positioning method of the drone is as follows: the drone is 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 in a straight line. After moving to the corresponding base point, it falls vertically so that the parking sign is close to the ground or a certain distance away from the ground.

[0073] Or use this method: Combine Figure 2As shown, some structural parts are required 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, the output shaft of the motor 4 is fixedly connected to the end of the threaded shaft 3, 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, 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. 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 request for vehicles that need to be charged to stop, 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 the owner to change vehicles.

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