Description

Technical Field

[0001] This utility model belongs to the field of electronic timing technology, specifically a touch-based distributed node wireless timing system. Background Technology

[0002] In sports training, cooking, scientific experiments, or team-based games, precise timing of multiple task phases or parallel tasks is often required. Existing timing solutions mostly rely on a single timer, which requires manual recording of multiple time points or setting them separately on multiple devices. This is cumbersome and makes it difficult to intuitively establish a correlation between physical location and timing tasks.

[0003] For example, Chinese utility model patent CN207780515U discloses a timer capable of sequential or reverse timing, but it does not involve wireless communication or a multi-node distributed layout. Chinese invention patent CN118649406A discloses an intelligent swimming timing touchpad, but its function is limited and cannot adequately meet the needs of single-task segmented timing or multi-task parallel timing. Therefore, there is an urgent need for a low-cost, flexible, and intuitive multi-node wireless timing solution. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a touch-based distributed node wireless timing system, which realizes distributed node wireless timing based on specific hardware structure and signal interaction, so as to solve the problems that a single timer in the prior art cannot meet the needs of multi-task and distributed timing, as well as the problems that existing intelligent timing solutions rely on software methods, are costly, and have unintuitive interaction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A touch-based distributed node wireless timing system includes a mobile terminal, a master wireless timing node, and at least one slave wireless timing node; the mobile terminal interacts with the master wireless timing node via a first wireless communication link; the master wireless timing node communicates with each of the slave wireless timing nodes via a second wireless communication link. The master wireless timing node and the slave wireless timing node are wireless timing nodes with identical physical structures. Each wireless timing node includes a housing. The front of the housing has a touch-sensing layer for receiving touch operation commands. Inside the housing is a control circuit board and a visual feedback module for displaying the timing status. The control circuit board integrates a main control module, which is electrically connected to the visual feedback module. The main control module integrates a touch detection module and a node wireless communication module. The touch detection module is electrically connected to the touch-sensing layer, and the node wireless communication module is used to establish the first wireless communication link and the second wireless communication link. The main control module of the main wireless timing node is configured as follows: Receive timing task configuration signal from the mobile terminal through the first wireless communication link; A timing control signal is sent to the designated wireless timing node via the second wireless communication link; In response to a touch on its own touch-sensing layer, a timing start signal is generated; The timing status signals from each slave wireless timing node are received via the second wireless communication link; The timing result data generated based on the timing status signal is sent to the mobile terminal through the first wireless communication link.

[0006] Furthermore, the master control module of the wireless timing node is configured as follows: The timing control signal is received from the main wireless timing node via the second wireless communication link; In response to a touch on its own touch-sensing layer, a timing event signal is generated and recorded, and the visual feedback module is controlled to provide a status indication. The timing event signal is sent to the main wireless timing node as a timing status signal through the second wireless communication link.

[0007] Furthermore, the visual feedback module is a light strip composed of multiple independently addressable LED beads.

[0008] Furthermore, the light strip has a ring-shaped layout.

[0009] Furthermore, the node wireless communication module is a Bluetooth Low Energy module.

[0010] Furthermore, the touch sensing layer is an ITO touch film.

[0011] Furthermore, a cross mark is provided on the upper surface of the housing, with the intersection of the cross mark located at the center of the upper surface.

[0012] Furthermore, the control circuit board also integrates a power management module and a battery; the power management module is electrically connected to the battery, the main control module, and the visual feedback module, respectively.

[0013] Furthermore, the battery is a rechargeable lithium battery, and the control circuit board is equipped with a Type-C charging interface and its management chip.

[0014] Furthermore, a fixing structure is provided on the outer side of the bottom cover of the wireless timing node, which is a ring magnet or an anti-slip silicone pad.

[0015] The beneficial effects of this utility model are as follows: This invention's touch-based distributed node wireless timing system, based on its unique hardware structure and signal interaction logic, achieves the following technical effects: (1) Distributed timing bound to physical space is realized: Through a hardware network constructed by a master node and multiple slave nodes, the system materializes and spatializes the abstract timing task. Each node can be fixed in a specific location (such as a kitchen stove or a training track point), so that its timing status is strongly associated with the physical location, fundamentally solving the problem that a single timer cannot manage multiple time points at the same time. (2) Provides an extremely intuitive interactive experience: The touch sensing layer and visual feedback module integrated on the node allow users to complete node binding, task initiation and completion confirmation simply by the natural action of "touching". The visual feedback module can dynamically perceive the time status, which greatly improves the efficiency and security of operation in busy scenarios. (3) Achieving extremely low system cost and high reliability: The system adopts a highly integrated main control module and solidifies the core control logic in the main node hardware, eliminating the need for external touch chip, independent Bluetooth module and background server that relies on continuous operation; This hardware-based collaborative architecture not only significantly reduces material costs, but also reduces failures caused by too many software layers or network latency, making the system more stable and reliable.

[0016] In summary, the touch-based distributed node wireless timing system of this utility model realizes distributed node wireless timing based on specific hardware structure and signal interaction, so as to solve the problems that a single timer in the prior art cannot meet the needs of multi-task and distributed timing, as well as the problems that existing intelligent timing solutions rely on software methods, are costly, and have unintuitive interaction.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0020] like Figure 1 As shown, the touch-based distributed node wireless timing system of this invention includes a mobile terminal, a master wireless timing node, and at least one slave wireless timing node. The mobile terminal establishes a Bluetooth Low Energy connection with the master wireless timing node through a first wireless communication link and performs data exchange; the master wireless timing node establishes a Bluetooth Low Energy network with each slave wireless timing node through a second wireless communication link for wireless communication.

[0021] The master and slave wireless timing nodes are wireless timing nodes with the same physical structure. For example... Figure 2 As shown, the wireless timing node is a disc-shaped device, comprising, from top to bottom: an upper cover 1, an ITO touch film 2, an LED strip 3, a control circuit board 4, a battery 5, and a bottom cover 6. The upper cover 1 and bottom cover 6 together form a disc-shaped housing, fixedly connected by screws 7. The control circuit board 4 is located inside the housing. The ITO touch film 2 is located on the front of the housing and forms a touch sensing layer for receiving touch operation commands. The LED strip 3 consists of multiple independently addressable WS2812B LED beads, forming a visual feedback module for displaying the timing status; in this embodiment, the LED strip has a ring-shaped layout. A fixing structure, either a ring magnet or an anti-slip silicone pad, is provided on the outer side of the bottom cover 6 of the wireless timing node. In this embodiment, a ring magnet is provided at the bottom of the bottom cover 6 to attract and fix the node to a metal surface. A cross mark 8 is provided at the center of the upper surface of the upper cover 1, providing a precise ranging reference point for the mobile terminal, facilitating quick and accurate measurement and determination of the relative positions between nodes during deployment, improving the convenience and accuracy of system deployment.

[0022] In terms of circuit structure, the control circuit board 4 is housed inside the casing. For example... Figure 3 As shown, the control circuit board 4 integrates a main control module, a power management module, and a battery 5. The main control module and the visual feedback module are electrically connected. In this embodiment, the main control module uses the TCA31A chip (U1) from Taisi Microelectronics. This single-chip system integrates a touch detection module, a processor core, and a node wireless communication module. The touch detection module is electrically connected to the touch sensing layer, and the node wireless communication module is used to establish the first wireless communication link and the second wireless communication link. Specifically, the node wireless communication module uses a Bluetooth Low Energy module; in this embodiment, a Bluetooth 5.1 LE RF unit is used. The touch detection module is directly connected to the ITO touch film 2 via an FPC connector. The GPIO port of the processor core controls the visual feedback module. The node wireless communication module transmits and receives wireless signals through an onboard PCB antenna.

[0023] The power management module uses an IP5306 chip (U2), which is electrically connected to battery 5, the main control module, and LED strip 3. It is responsible for battery charging and voltage conversion, providing a stable 3.3V operating voltage to all components of the system. Battery 5 is a rechargeable lithium battery, and the control circuit board 4 also has a Type-C charging interface and its management chip for charging battery 5.

[0024] In this embodiment, the main control module of the main wireless timing node is configured as follows: Receive timing task configuration signal from the mobile terminal through the first wireless communication link; A timing control signal is sent to the designated wireless timing node via the second wireless communication link; In response to a touch on its own touch-sensing layer, a timing start signal is generated; The timing status signals from each slave wireless timing node are received via the second wireless communication link; The timing result data generated based on the timing status signal is sent to the mobile terminal through the first wireless communication link.

[0025] In this embodiment, the master control module of the wireless timing node is configured as follows: The timing control signal is received from the main wireless timing node via the second wireless communication link; In response to a touch on its own touch-sensing layer, a timing event signal is generated and recorded, and the visual feedback module is controlled to provide a status indication. The timing event signal is sent to the main wireless timing node as a timing status signal through the second wireless communication link.

[0026] The working process of this novel touch-based distributed node wireless timing system is as follows: During the configuration phase, the mobile terminal generates a timing task configuration signal and sends it to the main wireless timing node via the first wireless communication link. When a user touches any wireless timing node, the touch sensing layer of that node detects the operation, and its main control module then controls the visual feedback module to generate a specific light change as a status indication. The main control module of the main wireless timing node records the association between this touch event and the configuration signal.

[0027] During operation, when a user touches the touch-sensitive layer of the main wireless timing node, its main control module generates a timing start signal and sends a timing control signal to the designated slave wireless timing node via a second wireless communication link. Each node starts timing or counts down according to preset logic, and the ring-shaped LED light strip 3 dynamically displays the current timing status.

[0028] When a user touches any of the slave wireless timing nodes, its main control module responds to the touch operation, generates and records a timing event signal, controls the visual feedback module to provide a status indication, and sends the timing event signal as a timing status signal to the main wireless timing node through the second wireless communication link.

[0029] During the data aggregation phase, the master control module of the master wireless timing node receives and aggregates the timing status signals from each slave wireless timing node, generates the final timing result data based on these signals, and sends the timing result data to the mobile terminal for display via the first wireless communication link.

[0030] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
