Description

Radar monitoring device and monitoring equipment

This creation relates to a monitoring system, especially a radar monitoring device and monitoring equipment.

Most of the existing surveillance systems set up one or more cameras in an indoor or outdoor environment, and rely on manpower to actively monitor the surveillance pictures from time to time to achieve the purpose of security surveillance. However, if the watcher does not watch the monitoring screen at all times, it is easy to cause monitoring loopholes. Take a monitoring system installed in a long-term care service agency as an example. It is necessary to rely on the caregiver to actively monitor the images from time to time to ensure the safety of the elderly. If the caregiver is busy and cannot actively monitor it, it is easy It was a long time after the accident that caused the elderly to fall and was only discovered, delaying the opportunity to get rescue.

In this regard, another surveillance system with image recognition capabilities has been proposed to solve the pressure and burden of the watcher's active surveillance work. However, the camera-based surveillance system needs to sacrifice the privacy of the monitored person, and image recognition also requires the surveillance system to have huge computing power to perform. In order to take into account the privacy of the monitored person, cameras can only be installed in public spaces or places with low privacy requirements, such as outside buildings, roadsides, offices or living rooms, etc., but not in locations where cameras are installed (such as toilets, Locker rooms, etc.) will also become a blind spot for security monitoring.

Therefore, wearable devices with a fall detection function (such as smart watches, detection necklaces, etc.) have been proposed to solve the problem of infringement of the privacy of the monitored person. However, once the monitored person forgets to put on the wearable device, or forgets to charge or replace the battery of the wearable device, or has to take off the wearable device for some reason (such as taking a bath), the wearable device will not be able to perform its functions. Some monitoring functions.

To this end, the main purpose of this creation is to provide a radar monitoring device and monitoring equipment that is not easily affected by the environment, can quickly detect accidents and prevent privacy infringement.

The radar monitoring device 10 can be installed, for example, on the ceiling, wall, partition, or cabinet height of the room 1, so that the detection range 11 of the radar monitoring device 10 (for example, a 120-degree sector field of view, a maximum detectable distance of 6 km) The ruler can cover a certain predetermined area in the room 1, for example, the entire shower room. This creation can also be installed outdoors for personnel entry and exit control, or installed on moving objects such as vehicles for blind spot monitoring to prevent large trucks from turning and dead corners, and can also be installed on bicycles or parking equipment to monitor billing.

In this embodiment, the radar monitoring device 10 at least includes a control unit 110, a signal transceiver 120, and a communication unit 130. The control unit 110 is electrically connected to the signal transceiver 120 and the communication unit 130. The signal transceiver 120 may include at least one transmitting antenna, at least one receiving antenna, and a signal processing circuit. The transmitting antenna is used to transmit an output electronic signal in the form of an output wave (ie, a detection wave) to a specific direction. The receiving antenna is used to receive an input wave (ie, an echo) from a specific direction, mix the output wave with the input wave, and convert the mixed wave into an input electronic signal. The signal processing circuit is used to convert an output signal from the control unit 110 through the process of digital conversion, amplification, and phase modulation into the above-mentioned output electronic signal, and to filter, amplify and compare the above-mentioned input electronic signal. The process of digital conversion is converted into an echo signal. The signal transceiver 120 of the present invention can be designed according to the actual needs of the number of antennas, the detection range, the direction of receiving and transmitting, and the signal processing method of the signal processing circuit.

After the radar monitoring device 10 is installed and activated, the radar monitoring device 10 can perform the task of accident detection. In order to clearly and briefly explain the spirit of this creation, the following will take as an example to detect whether a toilet in the bathroom is falling down.

Please also refer to FIG. 3. First, the control unit 110 can periodically output an output signal to the signal transceiver 120, so that the signal transceiver 120 sends a detection wave in a specific direction according to the output signal, as in step S101 Show. This detection wave will be projected on the object 2 (ie the toilet) within the detection range 11 of the radar monitoring device 10, and the object 2 will also reflect the detection wave back to the signal transceiver 120 of the radar monitoring device 10 as a return. Wave. At this time, the signal transceiver 120 receives the echo, mixes the echo with the detection wave, and generates an echo signal to the control unit 110, as shown in step S102.

Then, the control unit 110 compares the output signal with the echo signal corresponding to the output signal to estimate the moving speed of the object 2, as shown in step S103. For example, the radar monitoring device 10 is a detection device using Doppler radar. When the object 2 deviates from the wave source, the return wavelength will increase and the echo frequency will decrease; on the contrary, when the object 2 When moving toward the wave source, the return wavelength decreases and the return frequency increases; therefore, the velocity of the object 2 can be calculated based on the detected Doppler frequency shift. In this embodiment or other embodiments, the acceleration of the object 2 can be further estimated from the estimated speed.

After obtaining the current speed (or acceleration) of the object 2, the control unit 110 further determines whether a duration of the speed (or acceleration) is within a threshold range (for example, 0.1 second to 0.5 second) to determine whether the object 2 An accident occurs, as shown in step S104. The threshold range may be, for example, 0.01 second to 0.5 second, or 0.1 second to 0.5 second, or 0.01 second to 0.3 second, depending on the detected event. For example, to detect whether the object 2 falls down, the threshold range can be 0.1 second to 0.5 second. When the duration of the speed (or acceleration) of the object 2 is not within the threshold range, the control unit 110 returns to step S101 and continues to repeatedly execute steps S101 to S104. When the duration of the speed (or acceleration) of the object 2 is within the threshold range, the control unit 110 determines that the toilet has a fall accident, and therefore generates a warning signal, as shown in step S105. The frequency corresponding to the speed within the threshold range of this duration is approximately 100 Hz to 5000 Hz or 100 Hz to 500 Hz, depending on the detected event. For example, to detect whether the object 2 falls down, a frequency corresponding to the speed within the threshold range of this duration is approximately between 100 Hz and 500 Hz.

By using the radar monitoring device 10 provided by this creation to detect the occurrence of an accident, it can not only quickly detect the occurrence of the accident anytime and anywhere, so as to strive for the opportunity for rescue and assistance as much as possible, but also ensure that the privacy of the detected person is not affected.
