BeiDou-2 still inherits this system and service, and is currently in service. Compared with BeiDou-2, the service performance of BeiDou-3 has been greatly improved, and it can provide better services to users in my country and its surrounding areas. On the basis of compatibility with the RDSS system, BeiDou-3 uses three GEO satellites, innovatively adopts the generalized RDSS system and the RNSS+ short message communication system, refines the service type design, optimizes the operation mode design, greatly improves the system performance and user experience, and develops in the direction of scale, internationalization and high quality.

[0003] When working in the field, workers usually wear vital signs monitoring tools with Beidou positioning function, which can find the location of workers in the first time in case of accidents. At present, there are no mature and finalized products with integrated positioning, vital signs detection and satellite communication functions in China, as well as monitoring and rescue systems based on such products. Some R&D products have partial functions of type products, such as wireless portable helmets, wireless telemedicine equipment based on GSM networks, wireless sensor networks, GPS navigators, satellite phones, personal medical rescue equipment, etc., which are not designed for applications in special environments and lack an effective background support system. They all have the following problems: lack of integration of positioning, vital signs monitoring and communication within the system, poor anti-interference ability of communication, poor environmental adaptability, and due to the characteristics of Beidou short message communication, it will affect the transmission of signals in densely wooded jungles, and lack of communication guarantee capabilities in disaster environments.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0026] Figure 1 It is a schematic diagram of a vital signs monitoring system based on Beidou communication according to an embodiment of the utility model.

[0027] like Figure 1 As shown, the vital signs monitoring system based on Beidou communication includes a Beidou short message communication device and a wearable device, wherein the Beidou short message communication device is wirelessly connected to the Beidou satellite and the wearable device respectively, wherein:

[0028] The wearable device can be detachably fixed on the human body to obtain the vital signs information and positioning information of the personnel; the wearable device collects the vital signs data of the operating personnel in real time, and the vital signs data is sent to the Beidou short message communication equipment via wireless communication, and then the data is transmitted to the background control center via the Beidou satellite through the data modulation circuit and the power amplifier circuit.

[0029] The Beidou short message communication device is a portable device that can be detachably fixed on the surface and is used to receive vital signs information sent by the wearable device within a preset range. The Beidou short message communication device is suitable for emergency communication and command scenarios in scenarios such as mobile communication interruption, power outage or mobile communication coverage failure, and has reliable security encryption performance. Beidou short messages can be used for communication, positioning, scheduling and other operations.

[0030] Specifically, the Beidou short message communication device includes a first microcontroller, and a first Beidou positioning module, a first Beidou navigation module, a first Bluetooth module and a data storage module connected to the first microcontroller, and also includes a noise amplifier, a power amplifier circuit, and a first radio frequency transceiver chip. The first radio frequency transceiver chip is respectively connected to the first Beidou positioning module and the first Beidou navigation module, and is wirelessly connected to the Beidou satellite.

[0031] Beidou short message communication equipment integrates low noise amplifier, RF transceiver chip, power amplifier circuit, Beidou-3 dedicated baseband circuit, positioning module, Bluetooth circuit, etc., and can realize Beidou communication positioning function through external SIM card and passive antenna. The low noise amplifier circuit can filter and amplify the RF signal input from the input port, so that we don't need to connect an external low noise amplifier. The baseband processing capability can process 21 wave speeds at the same time, the power consumption is less than 0.7W, and the transmission power is ≥37dBm.

[0032] The wearable device includes a second microcontroller, and a second Beidou positioning module, a second Beidou navigation module, a second Bluetooth module and a second radio frequency transceiver chip connected to the second microcontroller. The second Beidou positioning module and the second Beidou navigation module are wirelessly connected to the first Bluetooth module through the second Bluetooth module, and are wirelessly connected to the Beidou satellite through the second radio frequency transceiver chip.

[0033] Beidou short message communication equipment and wearable devices are two separate devices. The intermediate data link relies on Bluetooth transmission, and the transmission distance can reach 100m in open areas. Therefore, in an operating area with a radius of 100m, operators do not need to carry two devices at the same time. They only need to carry wearable devices to complete the return of vital signs data. Beidou short message communication equipment can be placed in a relatively open place to avoid signal obstruction by human bodies or other obstacles, which may affect data transmission.

[0034] Preferably, the Beidou short message communication equipment also includes a first voice communication module connected to the first Bluetooth module, and the wearable device also includes a second voice communication module connected to the second Bluetooth module. Within the connection range of Bluetooth, the operator can make a voice call with the operator stationed at the Beidou short message communication equipment through the wearable device.

[0035] Figure 2 This is a schematic diagram of the structure of a vital signs monitoring device based on Beidou communication in one embodiment of the utility model. Figure 2 As shown, a vital signs monitoring device based on Beidou communication includes a housing, a display and the above-mentioned Beidou short message communication equipment, and the display displays current signal information, time information, and power information.

[0036] In addition, the housing is also provided with a confirmation button, an emergency call button, a power switch button, a Bluetooth switch button and a voice call button, each of which is provided with a circuit for realizing the function, and is connected to the first microcontroller. The button functions are shown in Table 1:

[0039]

[0040] Preferably, the vital signs monitoring device based on Beidou communication is provided with leading hardware equipment in the prior art for communicating with passive satellites, and the specific technical parameters are shown in Table 2:

[0041] Table 2: Technical parameters

[0042]

[0043] When working, the vital signs monitoring device is fixedly placed in an open area in the wild. Field workers wear wearable devices to work. The vital signs monitoring device and the wearable device are wirelessly connected via Bluetooth. The wearable device can display the distance to the vital signs monitoring device in real time. Within 100 meters, the wearable device obtains the vital signs information of the field workers in real time, and sends the vital signs information and location information to the Beidou satellite and the vital signs monitoring device respectively. When the signal in the environment where the field workers are located is poor, such as working in a dense forest, the wearable device cannot communicate directly with the Beidou satellite. At this time, the vital signs information and location information can be sent to the vital signs monitoring device via Bluetooth, and indirectly communicate with the Beidou satellite. The staff can also send work instructions to the workers wearing the wearable device in real time through the vital signs monitoring device.

[0044] The vital signs monitoring device is compact and easy to carry. Its fixed position can be changed as needed and it is suitable for working in environments with poor communication signals.

[0045] The utility model places Beidou short message communication equipment in an open area outdoors, and has outdoor workers wear wearable equipment to obtain vital sign information, and wirelessly sends the vital sign information and positioning information to the Beidou short message communication equipment through the wearable equipment. The Beidou short message communication equipment is wirelessly connected to the Beidou satellite to achieve positioning and communication. The workers only need to carry the wearable equipment to complete the return of vital sign data through the Beidou short message communication equipment. When in a special environment with poor signal and when there are obstacles blocking the signal, data transmission is efficiently completed to ensure the life safety of the workers.

[0046] In summary, the present invention can be implemented in hardware, or in software modules running on one or more processors, or in a combination thereof. Those skilled in the art should understand that a general data processing device such as a microprocessor or a digital signal processor (DSP) can be used in practice to implement some or all functions of some or all components in the embodiments of the present invention.
