[0025] The embodiments of the application will be described in detail below with reference to the drawings and examples.

[0026] The maze competition interactive experience device, also known as the maze competition device, has a mechanical part as shown in Figure 1 The figure shows two different maze patterns, and the mechanical part includes a bottom plate 1. In actual application, the circuit part can also be hidden under the lower part of the bottom plate 1, and the circuit part mainly includes a power supply, which generally adopts 24V DC power supply.

[0027] The bottom plate 1 is used to bear the three-dimensional track path, that is, track one 51 and track two 52 in the figure. The two tracks can be the same pattern to provide different players to compete at the same time, or can be different patterns to provide a player to play a “dungeon game”. The track one 51 and the track two 52 are respectively sleeved with a sleeve ring one 21 and a sleeve ring two 22, the sleeve ring one 21 is connected with a handle one 61, the sleeve ring two 22 is connected with a handle two 62, and the floor 1 is installed with an indicator light one 41 and an indicator light two 42. The above-mentioned tracks, sleeve rings, and handles are all good conductors, wherein the sleeve ring is integrally connected with the handle, a lead wire is led out on the handle, and one pole of the power supply is connected, and the other pole of the power supply is connected with the track.

[0028] Figure 2The circuit principle of a traditional maze competition interactive experience device is shown, wherein the sleeve ring 2 is sleeved on the track 5, the wire led out from the sleeve ring 2 is connected to the negative pole of the power supply, the track 5 is connected to the positive pole of the power supply through the intermediate relay coil 7, and the indicating lamp circuit controlled by the relay switch is led out between the positive pole and the negative pole, and the indicating lamp 4 is connected in the indicating lamp circuit. Meanwhile, the mechanical arm connection terminal 8 controlled by the relay switch can also be led out at the output end of the power supply, which is used for connecting the power supply to the input end of the mechanical arm, and the purpose is to provide a robot demonstration scheme. For example, when the player walks through the maze pattern with the sleeve ring 2 in hand; the robot end completes the competition in the same hardware environment, and who completes the competition in the shortest time is the winner.

[0029] Thus, in the structure shown, Figure 2 In the structure shown, the function is realized by using the working principle of the intermediate relay, the intermediate relay coil 7 is powered, the normally open point of the intermediate relay switch is closed, and the indicating lamp 4 is lit, so as to judge whether the sleeve ring and the guide rail are in contact. Specifically, the track 5 and the sleeve ring 2 are disconnected when there is no contact, and the circuit is closed when there is contact, the intermediate relay coil 7 is powered, and the judgment function is realized. The indicating lamp 4 can be lit based on the judgment of the intermediate relay switch control point, which is the basic circuit knowledge in the field, and will not be described here.

[0030] According to the above structure, the wire at the tail of the handle will inevitably bring inconvenience in use, especially when facing large and complex patterns, longer wires are needed, and the pulling and winding phenomenon will greatly reduce the experience and there is a certain risk.

[0031] Therefore, the present application provides a maze competition interactive experience device based on wireless induction, which provides three improvements that are mutually coordinated on the basis of the traditional maze competition interactive experience device. Firstly, a metal touch electrode sheet is connected at one end of the track, secondly, the wire connected on the handle is removed, and thirdly, a signal processing unit is introduced to judge whether the sleeve ring and the track are in contact based on wireless induction.

[0032] Referring again to Figure 1 The present application specifically installs a metal touch electrode sheet one 31 and a metal touch electrode sheet two 32 at one end of the track one 51 and one end of the track two 52 respectively, and the input end of the metal touch electrode sheet is a field effect tube structure, and the field effect tube is a voltage control element with extremely high input impedance, about tens of megohms, and the input end hardly consumes current, so that the weak induction voltage generated by the human body is enough to make the circuit flip by touching with hand.

[0033] Figure 3The circuit principle of the maze-based interactive experience device of the present invention is shown. A ring 2 is fitted onto a track 5. The ring 2 has no lead wires and forms an independent wireless handheld terminal with the handle. The track 5 is electrically connected to the metal touch electrode 3 and connected to the signal trigger terminal of the signal processing unit. The intermediate relay coil 7 is connected to the power supply terminal of the signal processing unit, and an indicator light circuit controlled by a relay switch is led out between the positive and negative terminals of the power supply. The indicator light 4 is connected in the indicator light circuit. Simultaneously, a robotic arm connection terminal 8 controlled by a relay switch can be led out from the power output terminal to connect the power supply to the input terminal of the robotic arm, aiming to provide a robot demonstration scheme. For example, when a player holds the ring 2 and navigates through a maze pattern, the robot, using the same hardware environment, completes a competition; whoever completes the competition in the shortest time wins.

[0034] Therefore, in Figure 3 In the structure shown, when not powered on, the guide rail 5 is connected to the metal touch electrode 3, which is a capacitive touch sensing chip. When the metal electrode approaches a human body or a metal part, a slight capacitance change occurs. This change is detected by the chip and converted into an electrical signal. This electrical signal serves as the trigger signal for the signal processing unit, controlling the circuit to turn on or off. The intermediate relay coil 7 is connected to the output terminal of the signal processing unit. The output voltage depends on the input voltage; in this embodiment, a 24V DC voltage is used, so the output voltage is 24V. When the metal collar 2 touches the metal guide rail 5, the output terminal of the signal processing unit outputs a 24V voltage, thereby controlling the intermediate relay coil 7 to be energized or de-energized, thus controlling the illumination of the indicator light 4.

[0035] The signal processing unit of this invention is based on a bistable trigger and a relay. When the collar 2 contacts the guide rail 5, the metal touch electrode 3 transmits the human body sensing signal to the bistable trigger, causing it to flip from a stable state to a transient state, outputting a high level. This activates the relay switching circuit, providing a stable DC power supply, which in turn energizes the intermediate relay coil 7, causing it to close. Furthermore, the relay switching circuit inside the signal processing unit has a charging / discharging capacitor at its input. Therefore, when the metal touch electrode 3 is connected to the guide rail 5 with an input voltage, the metal touch function is disabled. It only works when the metal touch electrode 3 is connected without an input voltage.

[0036] refer to Figure 4The bistable trigger specifically adopts NE555 time base integrated circuit. NE555 has 8 pins, which are defined as follows: pin 1, ground terminal; pin 2, trigger terminal, which gives high potential when the voltage of the pin drops to 1 / 3Vcc (or threshold voltage determined by the control terminal); pin 3, output terminal, which outputs high level or low potential; pin 4, reset terminal, which makes the timer work when the pin is connected to high potential, and resets the chip and outputs low potential when the pin is connected to ground; pin 5, control terminal, which controls the threshold voltage of the chip, and the default threshold voltage is 1 / 3Vcc and 2 / 3Vcc when the pin is connected to nothing; pin 6, threshold, which outputs low potential to the output terminal when the voltage of the pin rises to 2 / 3Vcc (or threshold voltage determined by the control terminal); pin 7, discharge terminal, which is connected to an OC gate for discharging the capacitor; and pin 8, power supply terminal, which provides high potential and supplies power to the chip.

[0037] In the embodiment, 24V DC power from the power supply is regulated through the series connection of diode VD1 and resistor R1, wherein R1 is a voltage dividing resistor, the input voltage of the chip is 4.5V-16V, and R1 plays a voltage dividing role in the circuit; diode VD1 uses its unidirectional conduction to play a circuit protection role in the circuit; the regulated voltage is connected to the reset terminal and the power supply terminal of NE555. Metal touch electrode sheet 3 is connected to the trigger terminal of NE555, and is connected to ground through capacitor C1 to ensure stable operation of the circuit. C1 is a stone capacitor, which plays a role of filtering high-frequency interference signals in the circuit, and can effectively improve the sensitivity of metal touch electrode sheet 3.

[0038] The output terminal of NE555 is connected to ground through the parallel connection of capacitor C2 and DC relay K. DC relay K is an internal relay of the signal processing unit, intermediate relay coil 7 is an externally controlled part, and serves as a DC load of the signal processing unit, and is connected to 24V DC power through a switch, which is a switch of DC relay K or a switch controlled by the energization and de-energization of the coil of DC relay K. C2 is an electrolytic capacitor, which plays a role of charging and discharging in the circuit; and DC relay K outputs a DC voltage signal through the energization of its coil.

[0039] When track 5 is in contact with metal touch electrode sheet 3, the generated induction signal is input to the trigger terminal of NE555, so that the trigger is flipped, the output terminal of NE555 outputs high level, the coil of DC relay K is energized, 24V DC power is output, intermediate relay coil 7 is energized, and indicator lamp 4 is lit. When track 5 is out of contact with metal touch electrode sheet 3, the input signal of the trigger terminal is 0, the trigger is flipped again, the output terminal of NE555 outputs low level, the coil of DC relay K is de-energized, the output power is disconnected, and intermediate relay coil 7 is also in a de-energized state.
