Description

Technical Field

[0001] This utility model belongs to the field of measurement and transmission technology, and in particular relates to a data measurement and transmission device. Background Technology

[0002] In applications requiring the collection of multiple types of data, such as physiological parameters like electrocardiogram, blood oxygen saturation, blood pressure, and pulse, different sensors are needed because these data cannot be collected using a single sensor. However, different sensors use different data transmission protocols, making it impossible to transmit data through a unified interface.

[0003] Therefore, existing data measurement and transmission devices of this type generally lack intelligent recognition capabilities, requiring users to manually configure the device's operating mode. This not only increases operational complexity but also makes it easier for operational errors to affect monitoring results in emergency medical scenarios. Secondly, regarding connection reliability, the lack of precise positioning design in existing technologies makes them prone to misalignment, leading to signal interruptions. Furthermore, in terms of modular expansion, existing technologies employ a fixed, integrated design, failing to allow for free switching between multiple physiological parameter modules. This necessitates users purchasing multiple single-function host devices, increasing operating costs and limiting the flexibility of monitoring functions. When sensors are damaged or require upgrades, the entire system often needs to be discarded, resulting in resource waste and failing to meet environmental protection requirements.

[0024] Example 1

[0025] Please see Figures 1-3 The figure shows a data measurement and transmission device in Embodiment 1 of this utility model, including a transmission control module 10 and at least one sensor front-end module 20 that can be connected to the transmission control module 10. In this embodiment, the transmission control module 10 can be shared with multiple sensor front-end modules 20, so that data collected by multiple sensor front-end modules 20 can be uploaded uniformly through one transmission control module 10.

[0026] Specifically, the sensor front-end module 20 and the transmission control module 10 are electrically connected via a connector and also connected via a magnetic structure. The connector specifically adopts an AFE universal interface, which can be a Pogo Pin connector 30. The sensor front-end module 20 includes an ID recognition circuit 21 and a sensor 22 for data measurement. The ID recognition circuit 21 identifies the ID identity information of the sensor 22 and transmits it to the transmission control module 10, so that the transmission control module 10 calls and loads the data transmission protocol corresponding to the ID identity information of the sensor 22, and realizes the transmission of information collected by the sensor 22. In specific implementation, the ID identities of different sensors and their corresponding data transmission protocols can be pre-established and preset in the transmission control module. The specific circuit structure of the ID recognition circuit 21 is not limited. For example, an existing coded resistor value recognition circuit can be used to identify the sensor identity by recognizing the coded resistor value (accuracy ±1%).

[0027] The transmission control module 10 includes a microcontroller 11, a power supply circuit 12 electrically connected to the microcontroller 11, and a data transmission module 13 electrically connected to the microcontroller 11. A connector is electrically connected to the microcontroller 11. Specifically, the ID information of the sensor 22 is transmitted to the microcontroller 11 through the connector. The microcontroller 11 then calls and loads the data transmission protocol corresponding to the ID information of the sensor. The microcontroller 11 is specifically an MCU (Microcontroller Unit), and its specific circuit structure is as follows: Figure 2 As shown. Furthermore, the data collected by sensor 22, after passing through the corresponding data transmission protocol, is transmitted externally via data transmission module 13.

[0028] Among them, such as Figure 1As shown, the power supply circuit 12 includes a charging interface, a charging management chip 122 electrically connected to the charging interface, an energy storage device 123 electrically connected to the charging management chip 122, and a voltage conversion circuit 124 connected between the charging management chip 122 and the microcontroller 11. The charging management chip 122 is specifically a TP5400, the energy storage device 123 is a battery (e.g., a size 7 battery), and the voltage conversion circuit 124 is a DC-DC converter, specifically a 5V to 3.3V DC-DC converter, depending on the system power supply voltage. In this embodiment, the data measurement and transmission device supports two power supply methods. The first method involves connecting to a 5V power supply through the charging interface, charging the battery while simultaneously supplying 5V to the system, and then converting the 5V to 3.3V via the DC-DC converter to power the system. The second method, when no power is connected to the charging interface, generates 5V from the battery to power the system, and then converts the 5V to 3.3V via the DC-DC converter to power the system. The data transmission module 13 includes a data interface and a data conversion circuit 131 connected between the data interface and the microcontroller 11, wherein the data conversion circuit 131 is specifically a USB to UART circuit. Specifically, the data interface and the charging interface are the same universal interface, which can be a USB Type-C interface 14.

[0029] In addition, to prevent reverse connection errors, this embodiment also features a special design for the magnetic attraction structure, specifically, as follows: Figure 3 As shown, the magnetic attraction structure includes a first magnetic attraction component group 41 disposed on the transmission control module 10 and a second magnetic attraction component group 42 disposed on the sensor front-end module 20. The first magnetic attraction component group 41 and the second magnetic attraction component group 42 are magnetically attracted to each other. Specifically, the first magnetic attraction component group 41 is disposed on the side of the transmission control module 10 near the connector, and the first magnetic attraction component group 41 includes two first magnetic attraction components 411 disposed at opposite ends on the corresponding side. The second magnetic attraction component group 42 is disposed on the side of the sensor front-end module 20 near the connector, and the second magnetic attraction component group 42 includes two second magnetic attraction components 421 disposed at opposite ends on the corresponding side. Preferably, the two first magnetic attraction components 411 have opposite magnetic properties, and the two first magnetic attraction components 411 and the two second magnetic attraction components 412 are magnetically attracted one-to-one, thereby avoiding the two modules being connected opposite each other. Of course, in other embodiments, the two first magnetic attraction components 411 can also have the same magnetic properties.

[0030] In addition, the magnetic attraction structure also includes a third magnetic attraction group 43 disposed on the transmission control module 10 and a fourth magnetic attraction group 44 disposed on the sensor front-end module 20. The third magnetic attraction group 43 and the second magnetic attraction group 42 repel each other, and the fourth magnetic attraction group 44 and the first magnetic attraction group 41 repel each other. The third magnetic attraction group 43 is disposed on the side of the transmission control module 10 away from the connector, and the fourth magnetic attraction group 44 is disposed on the side of the sensor front-end module 20 away from the connector, thereby avoiding docking on the non-connector side. The third magnetic attraction group 43 includes two third magnetic attraction elements 431 disposed at opposite ends on the corresponding side, and the fourth magnetic attraction group 44 includes two fourth magnetic attraction elements 441 disposed at opposite ends on the corresponding side. That is, magnetic attraction elements are provided at all four corners of the transmission control module 10 and the sensor front-end module 20.

[0031] In some alternative embodiments, sensor 22 can be a measurement sensor for measuring human physiological parameters, such as electrocardiogram, blood oxygen, blood pressure, pulse and other physiological parameters.

[0032] In summary, the data measurement and transmission device in this embodiment, by integrating an ID recognition circuit at the sensor's front end, can identify the sensor's identity information and transmit it to the transmission control module. This allows the transmission control module to automatically invoke the transmission protocol corresponding to the sensor to achieve data transmission, thus enabling the sharing of the transmission control module and eliminating the need for manual configuration of the device's operating mode. Furthermore, the connection between the sensor front end module and the transmission control module, using a magnetic and PogoPin connector, ensures precise positioning and prevents signal interruption.
