Description
Technical Field

[0003] However, in the prior art, due to the huge amount of data collected, the large number of operating personnel, and even one person can bind multiple wearable devices, the total number of front-end wearable devices actually used at the production site is large. Each front-end wearable device needs to establish a data connection with the base station and frequently perform data sending and backhaul functions, resulting in a large power consumption of the front-end wearable device, making it impossible to achieve both thinness and long battery life, which greatly affects the user experience. At the same time, each front-end wearable device needs to have a long-distance data transmission function, a large battery capacity, and complex supporting functions, resulting in a high usage and management cost of the front-end wearable device. In addition, in the prior art, some data collection functions can use mobile devices such as mobile phones and smart bracelets as hardware carriers. However, when the operating personnel carry the mobile device out of the production site, it will still output the detection data in the current environment to the base station, resulting in poor privacy protection for the operating personnel and relatively cumbersome and inconvenient switching operations during actual use.

[0018] (1) In a data communication system based on wearable devices provided by the present utility model, there are several relay wearable devices and several front-end wearable devices. The front-end wearable devices are responsible for monitoring the data of the current working environment and / or the physical signs of the workers. Among them, several front-end wearable devices can choose to achieve short-range Bluetooth communication with a relay wearable device, and the relay wearable device can achieve long-range communication with the base station based on technologies such as radio frequency signals, mobile data, or WiFi.

[0026] The following further details a data communication system based on wearable devices proposed by the present utility model in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present utility model will be clearer according to the following description and the claims.
[0027] Refer to Figures 1 to 4 , this embodiment provides a data communication system based on wearable devices, which realizes the simplification of wearable devices and optimizes the user experience while ensuring normal data communication.
[0028] In the data communication system, it includes a base station 3, several relay wearable devices 1 and several front-end wearable devices 2. Wearable devices can be understood as portable electronic devices that can be directly worn on the operator's body or integrated into clothing or accessories. It is set that both the relay wearable device 1 and the front-end wearable device 2 can be selectively assembled on the operator's body surface and move dynamically with the operator's movement, or can be selectively placed at a fixed position within the production site area. Among them, the relay wearable device 1 is limited to only move within the demarcated production site area, while the front-end wearable device 2 is not restricted by the area.
[0029] The relay wearable device 1 is provided with a first MCU and a first communication module. The first MCU is electrically connected to the first communication module. The first communication module is provided with a Bluetooth chip, a LoRa chip, a cellular network chip, a WiFi chip, and an NFC chip. A plurality of relay wearable devices 1 can simultaneously realize long-distance two-way data communication with the base station 3 based on any one of radio frequency signals, mobile data, or WiFi.
[0030] The front-end wearable device 2 is provided with a data acquisition module, a second MCU, and a second communication module. The data acquisition module is based on various sensors and is used to monitor various data of the current working environment and / or the physical signs of the operator in real time. The type of sensor can be specifically configured according to the type of detection item required, and will not be specifically limited in this embodiment. The second MCU is electrically connected to the data acquisition module and the second communication module respectively. The second communication module includes a Bluetooth chip. The front-end wearable device 2 can select to realize short-distance two-way data communication with any one of the relay wearable devices 1 based on Bluetooth technology. It is worth noting that in this embodiment, according to the actual area size of the production site, at least one group of relay wearable devices 1 can be selectively configured. If there are multiple groups of relay wearable devices 1 in the production site, and all the multiple groups of relay wearable devices 1 are within the Bluetooth connection range of a front-end wearable device 2, then the front-end wearable device 2 selects to communicate with a relay wearable device 1 with the best Bluetooth signal strength based on the Bluetooth signal strength.
[0031] The base station 3 is used to receive the data uploaded by the relay wearable device 1 and further send back a feedback signal to the relay wearable device 1.
[0032] In summary, in this embodiment, several front-end wearable devices 2 within the production area can freely capture the relay wearable device 1 within their Bluetooth radiation range and establish a Bluetooth connection with it. Since the number of front-end wearable devices 2 is generally more than that of the relay wearable device 1, a situation where multiple front-end wearable devices 2 are simultaneously Bluetooth-connected to a single relay wearable device 1 is formed. When the dynamically moving front-end wearable device 2 and the dynamically moving relay wearable device 1 maintain a Bluetooth-connectable distance, two-way data communication can be achieved between them. The relay wearable device 1 and the base station 3 achieve long-distance two-way data communication through any one of radio frequency signals, mobile data, or WiFi. Specifically, when the front-end wearable device 2 detects various data of the current working environment and / or the physical signs of the operator through the data acquisition module, it will first transmit the data to the relay wearable device 1 over a short distance via Bluetooth technology. The relay wearable device 1 will perform a preliminary screening process on the repeatedly collected data, and then the relay wearable device 1 will further transmit the data to the base station 3 over a long distance through any one of radio frequency signals, mobile data, or WiFi. Similarly, the feedback signal output by the base station 3 is first transmitted to the relay wearable device 1 over a long distance, and then the relay wearable device 1 further uses Bluetooth technology to split and transmit the feedback signal back to the corresponding front-end wearable device 2. Through the relay transmission function of the relay wearable device 1, an efficient communication between the front-end wearable device 2 and the base station 3 is established.
[0033] Based on the above technical solution, in this embodiment, the second communication module of the front-end wearable device 2 only needs to retain the Bluetooth chip. Due to the low-power consumption characteristics of Bluetooth transmission, the energy consumption of the front-end wearable device 2 is reduced, and the battery life is improved. Its product structure can achieve a more lightweight design, and the production and maintenance costs of the front-end wearable device 2 are lower. At the same time, since the relay wearable device 1 mainly realizes the relay transmission function of the signal, some or all of the functions of the data acquisition module can also be disabled, and a lightweight design can also be achieved, improving the battery life of the relay wearable device 1.
[0034] In addition, in this embodiment, the front-end wearable device 2 does not directly communicate with the base station 3. When the front-end wearable device 2 leaves the production site area, due to the distance limitation of Bluetooth technology, the front-end wearable device 2 and the relay wearable device 1 will automatically disconnect, that is, the communication between the front-end wearable device 2 and the base station 3 is interrupted, ensuring that data cannot be uploaded in the non-working state and protecting the privacy and security of the users in the non-working state.
[0035] Preferably, in one embodiment, the relay wearable device 1 is provided with a first power module, and the front-end wearable device 2 is provided with a second power module. The first power module and the second power module respectively include a first rechargeable battery and a second rechargeable battery. Electric energy is stored in the first rechargeable battery and the second rechargeable battery, which are respectively used to supply energy to the relay wearable device 1 and the front-end wearable device 2, ensuring that the relay wearable device 1 and the front-end wearable device 2 can be portably carried by the operator and can maintain functions such as long-term parameter detection and data communication.
[0036] Furthermore, in one embodiment, the first power module is further provided with a reverse power supply module, and the second power module is further provided with a power receiving module matching the reverse power supply module. When the first rechargeable battery and the second rechargeable battery are electrically connected, such as when the relay wearable device 1 and the front-end wearable device 2 are connected to each other through a charging cable, the relay wearable device 1 can temporarily serve as a power supply end and charge the front-end wearable device 2 reversely. Through the flexible charging method setting of the front-end wearable device 2, the battery capacity requirement of the front-end wearable device 2 is smaller, and a thinner and lighter design of the front-end wearable device 2 can be realized.
[0037] Preferably, in one embodiment, the relay wearable device 1 is further provided with a positioning module. The positioning module is electrically connected to the first MCU. The positioning module includes any one or more of a GPS chip, a Beidou chip, a GLONASS chip, a UWB chip, and an RTK module, which is used to realize the real-time positioning function of the relay wearable device 1. The positioning data of the relay wearable device 1 can be uploaded to the base station 3 or sent to the front-end wearable device 2. More specifically, since the front-end wearable device 2 and the relay wearable device 1 are connected through Bluetooth technology, the Bluetooth transmission distance is short, and the front-end wearable device 2 will only be Bluetooth-connected to one relay wearable device 1 at the same time. Therefore, by determining the accurate position of the relay wearable device 1, the approximate position range of the front-end wearable device 2 connected to the relay wearable device 1 can be determined. In this embodiment, the front-end wearable device 2 is not provided with a positioning module, that is, on the premise of realizing the rough positioning function of the front-end wearable device 2, the daily energy consumption and volume occupation of the front-end wearable device 2 are further reduced.
[0038] Preferably, in one embodiment, the relay wearable device 1 is provided with an indicator light, a buzzer, and a first SOS button. The indicator light, the buzzer, and the first SOS button are respectively electrically connected to the first MCU. When the operator carrying the relay wearable device 1 discovers a special situation or receives special situation information uploaded by the front-end wearable device 2, the first SOS button can be pressed to send an alarm message to the base station 3, and the indicator light and the buzzer can be further used as audible and visual alarms.
[0039] Further, in one embodiment, a second SOS button is provided in the front-end wearable device 2. The second SOS button is electrically connected to the second MCU. When the operator wearing the front-end wearable device 2 discovers a special situation, the second SOS button can be pressed to send an alarm message to the relay wearable device 1.
[0040] Preferably, in one embodiment, touch display screens are respectively provided in the relay wearable device 1 and the front-end wearable device 2. The touch display screens are used to implement data visualization and information interaction functions.
[0041] Preferably, in one embodiment, in addition to the Bluetooth technology, the first communication module of the relay wearable device 1 and the second communication module of the front-end wearable device 2 may further include a Zigbee chip, a UWB chip, an ANT / ANT chip, and an RFID chip. Since the front-end wearable device 2 does not need to perform long-distance data communication with the base station 3, any third-party device only needs to be adapted with any one of the above communication protocols to achieve data transfer communication with the relay wearable device 1, solving the problem of difficult access of third-party devices and making the present utility model have better applicability.
[0042] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the above embodiments. Even if various changes are made to the present utility model, provided that these changes fall within the scope of the claims of the present utility model and its equivalent technologies, they still fall within the protection scope of the present utility model.
