Description

Technical Field

[0001] The utility model relates to the technical field of alarm assistance, in particular to a radar presence sensor with a voice recognition assistance function. Background Art

[0002] All radar presence sensors currently on the market are generally used in places with a certain degree of personal privacy, such as bathrooms and bedrooms, as vital sign monitoring equipment in the current space. When used in the elderly care and medical field, radar presence sensors are often used to detect whether the elderly or people with serious diseases stay in the bathroom. In this case, a set of help-seeking equipment is also needed to ensure that the elderly or patients can actively seek help in time when encountering emergencies.

[0003] However, relying solely on radar presence sensors may not be enough to deal with all situations. Especially when the elderly or patients encounter emergencies and need help, adding a set of help-seeking equipment seems necessary. But doing so not only increases the procurement cost, but also requires consideration of equipment installation and maintenance issues, and also takes up more space.

[0004] A radar presence sensor with voice recognition help-seeking function undoubtedly provides an innovative solution to the above problems. By adding a voice recognition module inside the original radar presence sensor, this sensor can not only continue to perform the vital signs monitoring task in the current space, but also respond and transmit help-seeking information in a timely manner through voice recognition technology when the elderly or patients need help.

[0005] This design not only saves the cost of adding a set of help-seeking equipment, but also simplifies the installation and maintenance process of the equipment, while saving valuable equipment installation space. More importantly, it improves the efficiency and convenience of elderly care medical services, so that the elderly or patients can get more timely and effective help when encountering emergencies. To this end, a radar presence sensor with voice recognition help-seeking function is proposed. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the utility model provides a radar presence sensor with a voice recognition help-seeking function, which solves the problem that the elderly care and medical fields need to use both radar presence sensors and help-seeking devices. This solution integrates vital sign monitoring and voice active help-seeking into the same device, saving multiple costs. At least it provides a beneficial choice.

[0007] The technical solution of the embodiment of the utility model is implemented as follows: a radar presence sensor with a voice recognition help-seeking function, comprising a radar sensing module, a communication circuit module, a power circuit module, a server processing terminal and a voice recognition module;

[0008] The voice recognition module is connected to the communication circuit module, the radar sensing module is electrically connected to the communication circuit module, the communication circuit module is wirelessly connected to the server processing terminal, and the power circuit module is respectively connected to the radar sensing module and the voice recognition module and provides power.

[0009] Further preferably, the speech recognition module includes a sound pickup microphone and a noise reduction microphone.

[0010] Further preferably, the communication circuit module includes a cellular network, WIFI, RF radio frequency and Bluetooth module.

[0011] Further preferably: the power circuit module is equipped with an external power socket.

[0012] Further preferably, the voice recognition module and the radar sensing module work relatively independently.

[0013] Further preferably, the radar sensing module includes a radar sensing chip.

[0014] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0015] 1. The radar presence sensor with voice recognition help function only needs to add a voice recognition module inside the traditional radar presence sensor, and the original radar presence sensor structure and circuit do not need to be changed. Voice recognition uses monitoring to pick up environmental sounds at any time, and through the screening and identification of entry instructions, it replaces the separate help device to perform the corresponding help processing, and can judge whether the help is successful through voice broadcast, flashing lights, etc. One machine has two uses, saving the cost of purchasing, installing and maintaining an additional set of help equipment, and saving equipment installation space.

[0016] 2. The voice recognition function of the utility model can work normally in online or offline situations. It does not need to be sent to the background server for remote recognition. It can be processed at the edge. When a large number of terminal users are concurrent, it can significantly reduce the computing power of the cloud server and reduce energy consumption. Once the voice recognition function program is written, the program and entry instructions will not be lost when the device is restarted or the power is off.

[0017] 3. The program of the speech recognition chip of the utility model can be preset before leaving the factory, and can also be upgraded online during user use, including upgrading functional programs and updating entry instructions, to achieve personalization of dialects in specific regions, solve the problem of satisfying the accuracy of regional dialects, and adapt to the personalized needs of users.

[0018] 4. The local voice recognition chip solution of the utility model fully meets the needs of alarm assistance equipment. Compared with the voice chip solution of the online retrieval background, it has the characteristics of low cost and stable operation, which is in line with the market positioning of alarm assistance equipment.

[0019] 5. It is only necessary to add a voice recognition module inside the traditional radar presence sensor. The original radar presence sensor structure and circuit do not need to be changed. The voice recognition module and the radar sensing module work relatively independently without mutual dependence and interference.

[0020] The above summary is for the purpose of description only and is not intended to be limiting in any way.

In this way, on the capacitor side, it is converted into the size of the capacitor charge and the charging speed. At the output end of MIC, it is represented as an electrical signal whose amplitude and frequency change with the sound input, which is related to the size of the MIC input current in the second point.

[0049] In one embodiment, specifically: the voice recognition module and the radar sensing module work relatively independently without mutual dependence and interference.

[0050] In one embodiment, specifically: the radar sensing module includes a radar sensing chip.

[0051] Among them, see Fig. 9 The radar sensing module includes a radar sensing chip U4. The radar sensing module is mainly used to monitor whether there are human vital signs within a certain range. When a vital sign changes within the current space or when a vital sign changes, the module sends an instant vital sign signal to the communication circuit module.

[0052] In this embodiment, specifically, the radar sensing module is mainly used to monitor whether there are human vital signs within a certain range. In the technical solution, this solution quotes the prior art, a known public authorized patent (publication number: CN110522413A), which discloses a vital sign monitoring system. The specific monitoring steps are as follows: (S1), entering the patient's standard vital sign data in the terminal, the data including standard body temperature, respiration, blood pressure, heart rate, pulse and blood oxygen concentration; (S2), placing the electronic thermometer, respiration monitor, blood pressure monitor, heart rate monitor, pulse monitor and blood oxygen monitor on the patient's body to collect data; (S3), the The electronic thermometer, respiratory monitor, blood pressure monitor, heart rate monitor, pulse monitor and blood oxygen monitor collect various vital signs data of the patient and transmit them to the terminal; (S4), the terminal displays various vital signs data of the patient in real time; (S5), the vital signs comparison and analysis module compares the monitored real-time vital signs data of the patient with the standard vital signs data of the patient.
