Description

System and method for recharging remote control mobile unit automatically using magnetic material}

The present invention relates to an automatic charging technology of a remote control mobile unit, and more particularly, to easily position the remote control mobile unit on a charging platform and to automatically charge the remote control mobile unit without a separate charging connector connection operation as well as a battery replacement. The present invention relates to an automatic charging system and method for a remote control mobile unit using a magnetic material.

Recently, many studies have been conducted in the field of remote control technology.

Remote control technology is a technology that allows mobile units operating on the ground or in the air to freely control various types of operations such as progress, stop, and rotation through a remote control device at a remote location.

Indeed, numerous models with this remote control technology have been manufactured and marketed. In particular, the scope of application of remote control technology, such as toys, field surveys, military use, and space exploration, has become very large.

On the other hand, the RC mobile unit (Remote Control mobile unit) is a mobile device to which such a remote control technology is applied. RC mobile units are implemented in various forms such as vehicles, ships, airplanes, helicopters, etc., and are used not only for simple hobbies, but also for exploring places that humans cannot actually access or for obtaining military information. Is extensive.

Such RC mobile units, in particular RC helicopters and the like, generally use lithium polymer batteries as power sources. Lithium polymer battery is a next-generation secondary battery with high stability, light weight, and simple manufacturing process because it uses a polymer (polymer) in solid or gel state as an electrolyte. Such lithium polymer batteries are mainly used in MP3s, mobile phones, and laptops.

However, lithium polymer batteries in general electronic products have a PCM (protective circuit) inside the pack to control charging / discharging. However, a typical lithium polymer battery applied to an RC mobile unit has no PCM. This is because when the PCM is mounted in an RC mobile unit requiring a high discharge rate, high discharge is inhibited.

Therefore, the RC mobile unit requires extra care to charge the battery so that it is not completely discharged.

There is a problem. In particular, when the volume of the RC mobile unit becomes large or the size of the rechargeable battery used is large, it is cumbersome to replace the battery because a large number of personnel are required to replace the battery. In the case of charging the mobile unit, the connection of the charging connector is not easy, which causes a problem of time and cost inefficiency for charging. In addition, if the RC mobile unit is not correctly positioned to a predetermined position that can perform charging under the control of the user, there is a problem that the user needs to move directly.

Prior to the description of the specific contents of the present invention, for the sake of understanding, an outline of the technical problem to be solved by the present invention is first presented.

The RC mobile unit automatic charging system can be charged and the platform can be expanded regardless of the position of the RC mobile unit.

The RC mobile unit automatic charging system includes a master unit (MASTER) and N slave charging cells (charging cell).

The master unit connects a charger with the charging cells and also synchronizes the operation of the charging cells.

The charging cell provides a reference voltage to the other charging cells and connects its terminal to the appropriate charger terminal.

First, the system scans the terminal location and voltage by assigning one of the charging cells as a reference voltage and recording its terminal voltage for the remaining charging cells. Accurate positioning can be determined by applying the process sequentially to all charging cells.

The RC mobile unit then becomes operational again and the RC mobile unit automatic charging system returns to standby mode.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings in order to clarify the solutions of the technical problems of the present invention. However, in describing the present invention, when it is determined that the detailed description of the related known technology or configuration may make the gist of the present invention unclear, the detailed description thereof will be omitted. In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to intention or custom of a user, an operator, or the like. Therefore, the definition should be made based on the contents throughout the specification.

1 shows an example of a remote control mobile unit automatic charging system using a magnetic material according to the present invention.

As shown in FIG. 1, a remote control mobile unit automatic charging system using a magnetic material according to the present invention includes charging cells constituting a charging platform and a master unit controlling the charging cells. unit).

Charging cell charging cell )

Each charging cell is a semi-independent system and includes a terminal array, a switch (e.g., relay or CMOS analog switch, etc.) array, a cell control unit, an IR communication device set (e.g., an IR LED and an optical And a flat conductive area serving as a contact terminal with the RC mobile unit.

2 shows the maximum width of the charging cell.

Referring to Figure 2, the maximum width of the conductive plane (HexTerm) of each charging cell is designed to be less than half of the distance between the two nearest terminals of the target RC helicopter. If the model is designed to be used for two or more helicopters, it should be based on the closest distance of all models.

For example, if helicopter A has three terminals (a, b, c), and the distances are ab = 80 mm, ac = 60 mm, and bc = 100 mm, respectively, the maximum width of the conductive plane is 30 mm (30 mm = ac / 2). Should be smaller than The reason is to avoid short circuits by the terminals of the RC helicopter.

3 shows an example of a charging cell used in the present invention.

4 shows a switching array of charging cells used in the present invention.

The cell control unit HexMCU of each charging cell has an identifier, for example, a unique number (UN). The unique number is used in the scanning process and has a range limit, for example, from 0 to 63. Actually, the range limit can be arbitrarily set, but it must be set in advance so that the master unit MASTER can operate efficiently. The range of the unique number (UN) determines the maximum size of the platform. In addition, the cell controller HexMCU must be able to identify the voltage difference and store information about the voltage difference. For example, the function may be performed by an internal analog to digital converter (ADC) and an internal memory.

The cell control unit HexMCU does not need to have a data output port, but a data input port must be provided. In addition, the cell controller HexMCU should include a port for controlling the switch array.

The terminal array (HexT-Hub) of each charging cell must include at least a power supply (Vcc) terminal, a ground terminal, each charger terminal, a clock input terminal, a data input terminal and two IR communication terminals. Additional pins may be included for structural purposes.

The IR communication unit IR-Set of each charging cell is connected to the master unit MASTER, not the cell control unit HexMCU. Terminals may be provided in the terminal array HexT-Hub.

The switch array HexMatrix of each charging cell allows the conductive plane HexTerm to be connected to the pins of the terminal array HexT-Hub which are connected to the appropriate charger terminals. The switches of the switch array HexMatrix are electronically controlled by the cell controller HexMCU. The switch array HexMatrix performs a switching operation between as many terminals as the number of cells of the battery plus one.

For example, E-sky helicopters have two or three cell batteries. A design for widespread use in both types is to allow the conductive plane (HexTerm) to toggle on four pins of the terminal array (HexT-Hub). Preferably, by connecting as many switches as possible to minimize the information from the cell control unit HexMCU, the amount of required pins is reduced and the size of the cell control unit HexMCU is reduced.

Master unit master unit )

The master unit MASTER includes at least one charger, a terminal array, a switch array, and a charging controller. The switches of the switch array may be implemented as relays or CMOS analog switches.

The terminal array MasterT-Hub of the master unit includes at least a power supply (Vcc) terminal, a ground terminal, a terminal corresponding to each charger terminal, a clock output terminal, a data output terminal and two IR communication terminals. do. Additional pins may be included for structural use.

The switch array MasterMatrix of the master unit MASTER provides a toggle operation between the “charger terminal” or “safe reference voltage” and the pins of the terminal array MasterT-Hub. Re-arrangement of terminal order does not occur in the master unit MASTER (this function is performed by the charging cells). Thus, the switch array MasterMatrix can be a combined array of toggle switches controlled by only one port (on = "connect to charger, off =" connect to reference voltage ").

5 shows charging cells connected to a master unit.

The charging control unit of the master unit (MASTER) synchronizes the operation of all charging cells. The charging control unit should be aware of the unique number range of the charging cell. The charging control unit includes two IR communication terminals directly connected to the terminal array MasterT-Hub, a clock output terminal connected to the terminal array MasterT-Hub, a terminal for controlling the switch array MasterMaster, and a charger state. It may include the number of terminals needed for reading (eg, E-sky charger: 2) and a terminal for a separate user interface.

The master unit MASTER may provide a safe and stable voltage to the entire charging cell through the power supply Vcc and the ground pin of the terminal array MasterT-Hub.

Scanning process ( scanning process )

An embodiment will be described for understanding the scanning process of the present invention.

6 shows an RC helicopter landing on a remote control mobile unit automatic charging system using a magnetic material according to the present invention.

First, it is assumed that the unique number (UN) range of the charging cell is 0 to 15.

Referring to FIG. 6, there is shown a honeycomb-type charging platform composed of charging cells assigned unique numbers 1 to 12. The conductive planes (HexTerm) of the charging cells may each have a regular hexagonal shape. There may be a gap between each conductive plane (HexTerm) or an insulating material may be used to prevent short circuit between charging cells.

Assuming that the RC helicopter uses a three cell battery, the charger has four terminals (the number of cells in the battery +1). The terminals of the RC helicopter are ground (yellow: 0V), V1 (magenta: 3.6V), V2 (blue: 7.2v) and V3 (red: 10.8V).

The terminals of the RC helicopter are arranged on the skid, for example, in the form of a rectangle of 80 mm x 120 mm. The maximum width of the hexagonal conductive plane (HexTerm) should be less than 40 mm to prevent short circuits.

The RC helicopter provides information that it has landed via an IR set. The master unit MASTER transmits a control signal through an IR set to cause the RC helicopter to stop the electronic driving circuit operation of the RC helicopter. The master unit MASTER then starts the scanning process.

First, the master unit MASTER transmits a control signal through the data output pin of the terminal array MasterT-Hub to cause the charging cell 0 assigned with the unique number 0 to set its conductive plane HexTerm to the reference voltage. Connect and check its HexTerm voltage on all other charging cells.

Note that all charging cells are connected in parallel to the master unit (MASTER), so there must be a number addressing order.

A certain amount of time is given to ensure the minimum time for accurate reading record.

Since there is no charge cell 0, all other charge cells cannot get any value this round. Then, the master unit MASTER transmits a control signal to cause the charging cell 1 to connect its conductive plane (HexTerm) to a reference voltage, and checks its conductive plane (HexTerm) voltage for all other charging cells. Do it. Since the charging cell 1 is not in contact with the terminals of the RC helicopter, all other charging cells get no value this round. Repeat the above process for the charging cell 2. However, in the charging cell 3, read information is generated. This scanning routine can be continued until the charging cell 15 can be obtained with the following summary information.

Round 3: Cell 5 = 0v, Cell 7 = 10.8v, Cell 10 = 7.2v, Cell 11 = 3.6v.

Round 5: Cell 3 = 0v, Cell 7 = 10,8v, Cell 10 = 7.2v, Cell 11 = 3.6v

Round 7: Cell 3 = 0v, Cell 5 = 0, Cell 10 = 0v, Cell 11 = 0v

Round 10: Cell 3 = 0v, Cell 5 = 0, Cell 7 = 3.6v, Cell 11 = 0v

Round 11: Cell 3 = 0v, Cell 5 = 0, Cell 7 = 7.2v, Cell 10 = 3.6v

Note that the negative reading results are interpreted as 0v. This is an ADC setting, but can also be implemented programmatically. #noReff changes based on the ADC, so use it as a full-scale value.

After round 15 is performed, the master unit MASTER stops scanning because round 16 does not exist due to the unique number range. The master unit MASTER then transmits a control signal to cause all charging cells to connect their conductive plane (HexTerm) to the charger pin equivalent to the highest reading read.

Then, the charging cells 3 and 5 are connected to the 0v line, the charging cell 11 is connected to the 3.6v line, the charging cell 10 is connected to the 7.2v line, and the charging cell 7 is 10.8v line Is connected to.

When enough time is allowed for the cell control unit HexMCU to respond, the master unit MASTER toggles its switch array MasterMatrix from " reference voltage " to " charger ". And charging starts.

The master unit MASTER continuously monitors the error of the charger or the end of charging. If any error occurs or charging ends, the master unit MATO toggles the switch array MasterMatrix back to the " reference voltage " and stops IR communication. The RC helicopter then recognizes the interruption of the IR communication as a "end of charge" message and prepares for takeoff by allowing its electronic drive circuit to operate again.

According to an embodiment of the present invention, auto-assignment of a unique number (UN) is possible (trade off: a data output channel is required for the cell control unit HexMCU, and complexity and price increase).

In addition, if the cell control unit HexMCU can respond to the master unit MASTER, a unique number (UN) assignment routine can be executed by power up, which is added to the modularity. . This facilitates the update of the automatic charging system according to the invention. For example, when a user wants a larger area, the user can operate by simply purchasing a separate charging cell and connecting power.

In addition, IR over-excitement deafening (IROD) for outdoor use may be considered. This is basically a system that prevents IR receivers from being constantly excited by other light sources (ie, the sun or heat source). Given that shadows are created when the RC helicopter lands, only the IR sets just below the RC helicopter need to operate. The defening system may be a high pass filter (HPF) or a simple series capacitor that adjusts the pulse stream frequency between the IR set and its terminals.

Simultaneous multiple charging is also possible (Tradeoff: Cell Control Channel (HexMCU) requires data output channels, more chargers and unique number assignments for each mobile unit, switch array of master unit and charging cell Complexity and number of terminals increase, and overall complexity and price increase). That is, due to the modular nature of the charging cell, it is possible to charge a larger number of mobile units at the same time.

Figure 7 shows another example of the remote control mobile unit automatic charging system using a magnetic material according to the present invention.

As shown in FIG. 7, the present invention may use circular or other types of charging cells.

According to one embodiment of the invention, the charging cell can supply power to the RC helicopter using a magnetic material.

8A to 8C show an example of a remote control mobile unit automatic charging system using a magnetic material according to the present invention.

8A-8C, the RC helicopter has a magnetic material terminal located on a skid. Each unit charging cell constituting the platform includes a magnetic material connected to a charger terminal. In this case, the conductive plane (HexTerm) is made of nonmagnetic material such as aluminum. In addition, the skid of the RC helicopter may be made of a nonmagnetic material.

As shown in Fig. 8a, the remote control mobile unit automatic charging system using the magnetic material according to the present invention is in a standby state, for example, before the RC helicopter lands. As shown in FIG. 8C, after the RC helicopter lands, the magnetic material of the charging cell comes into contact with the magnetic terminal of the RC helicopter by the attraction force between the magnetic terminal of the RC helicopter and the magnetic material of the charging cell.

In one embodiment, the charging cell is a flat conductive area in contact with the battery terminal of the RC mobile unit and the magnetic material of the charging cell, and the conductive plane is a battery terminal and the charging cell of the RC mobile unit And a cell controller for controlling the switching element so as to contact the magnetic material of the magnetic material so that the magnetic material of the charging cell is connected to the charger terminal.

As described above, the remote control mobile unit automatic charging system and method using the magnetic material according to the present invention, the RC mobile unit is easily located on the charging platform, and also replaces the battery automatically as well as the RC mobile unit without a separate charging connector connection operation Allowing the unit to charge provides the advantage of improving user convenience. Furthermore, when the battery is replaced or recharged, it prevents a fire or an electric shock due to user's carelessness and provides the advantage of improving the expandability.
