The receiving and transmitting are in opposite directions.

[0008] The second product uses the principle of object reflection. Black objects reflect very weakly. Two colors with large color difference are used to distinguish them at the place of use. Generally, black is used. The transmitting tube transmits all the time and the receiving tube receives all the time. If the receiving tube receives a signal, it proves that it is working in the effective area. When the receiving tube does not receive a signal, it proves that it is working in the invalid area. Different working areas are distinguished by these two states;

[0009] The third type of product has two working modes. One is like a remote control, where the transmitter and receiver are not in the same place. When there is an obstacle in the middle tone, the signal will be interrupted and a reaction will occur. The second is that the receiver and transmitter are in the same place, taking advantage of the reflective properties of the object, and there will be a reaction when an object is detected.

[0041] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] like Figure 1 The flowchart of the infrared target object tracking and detection method of the present invention is shown, comprising:

[0043] Step S101, sequentially controlling a plurality of infrared emitting tubes arranged side by side to emit infrared signals, wherein the infrared signals include identification information for identifying the infrared emitting tubes;

[0044] Step S102, parse the identification information from the infrared signal received by the infrared receiving tube, and determine the position of the target object according to the infrared signal emission direction of the infrared transmitting tube identified by the identification information.

[0045] Specifically, the identification information is preferably an address value, and each infrared transmitting tube has a fixed address value. Step S101 controls the infrared emission to sequentially transmit infrared signals containing fixed address values. Step S102 receives the infrared signal through the infrared receiving tube, and resolves the address value of the transmitted signal to know which direction the target object is, thereby realizing object recognition.

[0046] The present invention transmits an infrared signal containing identification information through an infrared transmitting tube, receives the infrared signal through an infrared receiving tube, determines in which infrared transmitting tube the target object is located in the infrared signal transmitting direction, and thus determines the position of the target object.

[0047] In one embodiment, the step of parsing the identification information from the infrared signal received by the infrared receiving tube and determining the position of the target object according to the infrared signal emission direction of the infrared transmitting tube identified by the identification information specifically includes:

[0048] A plurality of infrared signals are received from the infrared receiving tube within a preset time, a plurality of identification information are respectively parsed out from the plurality of infrared signals, the infrared signal emission direction of the infrared transmitting tube identified by the identification information of the infrared signal detected initially is taken as the starting direction, and the infrared signal emission direction of the infrared transmitting tube identified by the identification information of the infrared signal detected last is taken as the ending direction, to determine the movement of the target object, and the moving direction is: moving from the starting direction to the ending direction.

[0049] Specifically, when the address value of the transmitted signal is parsed from the infrared signal, it can be known that there is a target object in that direction. After obtaining a direction, it is detected whether there is an infrared signal in another direction. If so, it proves that the object has moved.

[0050] For example, for Figure 2 The arrangement of the infrared transmitting tube is shown in the figure. When an object appears at the R end in the effective area, it moves to the L end. The detection process is that the infrared receiving tube first receives the infrared signal at the R end, and then if the infrared signal at the L end is detected within a certain period of time, the target object moves to the L end.

[0051] This embodiment can achieve effective tracking of moving objects.

[0052] In one embodiment, the step of parsing the identification information from the infrared signal received by the infrared receiving tube and determining the position of the target object according to the infrared signal emission direction of the infrared transmitting tube identified by the identification information specifically includes:

[0053] Only one infrared signal is received from the infrared receiving tube within a preset time, the identification information is parsed from the infrared signal, and it is determined that the target object is stationary in the infrared signal emission direction of the infrared transmitting tube identified by the identification information.

[0054] For example, for Figure 2 The arrangement of the infrared transmitting tube is shown in the figure. When an object appears in the effective area and stays at the R end, the detection process is that the infrared receiving tube first receives the infrared signal at the R end, and then if no infrared signal is detected at the L end within a certain period of time, then the target object stays at the R end.

[0055] This embodiment can achieve effective detection of stationary objects.

[0056] In one embodiment, it also includes:

[0057] The fighting component of the fighting remote-controlled object is controlled to follow the position of the target object.

[0058] The present invention is preferably applied to fighting remote control cars or remote control toys. Both parties in the battle are moving toys or objects. In actual battles, since both parties are moving, it is difficult to aim at the fighting series of toys and it is difficult to hit the opponent. During the operation, the user must first control the direction and secondly observe the timing to attack the opponent, which is quite difficult for younger users.

[0059] The application of this technology will greatly reduce the difficulty of operation. By applying the present invention, an attack key is added to the product. The combat component automatically follows the position of the target object, which greatly reduces the difficulty of combat operation of the combat product, increases the number of attacks, and thus increases the playability and fun of the product.

[0060] The application of the present invention will have the following obvious improvements:

[0061] 1. It can detect moving objects, and then follow them through the cooperation of the signal point master control program. At this time, the user only needs to focus on the attack timing and launch the attack.

[0062] 2. Use more than three infrared transmitting tubes to transmit signals. The main program can cooperate with the operation to increase the prediction of moving objects. This will have a good tracking effect and greatly reduce the target tracking loss. This is difficult to achieve with general technology and algorithms.

[0063] 3. In the automatic follow mode, manual operation can also be performed, allowing users to experience the fun of intelligent control.

[0064] like Figure 3 FIG. 1 is a flowchart of an infrared target object tracking and detection method according to a preferred embodiment of the present invention. The infrared transmitting tube is set as follows: Figure 2 As shown, the method includes:

[0065] Step S301, power on and start;

[0066] Step S302, sequentially controlling a plurality of infrared emitting tubes arranged side by side to emit infrared signals, wherein the infrared signals include address values ​​for identifying the infrared emitting tubes;

[0067] Step S303, if the first infrared signal is detected, execute step S304, otherwise re-execute step S302;

[0068] Step S304, parsing the first address value from the first infrared signal, and determining that the target object is in the first infrared signal emission direction of the first infrared emitting tube indicated by the first address value;

[0069] Step S305, if the second infrared signal is detected within the preset time period, execute step S306, otherwise it is determined that the target object is stationary in the emission direction of the first infrared signal, and execute step S302;

[0070] Step S306, parse the second address value from the second infrared signal, determine that the target object moves to the second infrared signal emission direction of the second infrared emitting tube indicated by the second address value, and execute step S302.

[0092] In one embodiment, the infrared signal emission directions of the plurality of infrared emitting tubes 22 are fanned out toward both sides of the middle infrared emitting tube 22 with the middle infrared emitting tube 22 as a reference.
