Description

Portable personal environment parameter measuring device

Technical Field

The present invention relates to the field of health and/or environmental monitoring technologies, and more particularly to a portable personal environmental parameter measuring device.

Background

As the indoor air pollution problem becomes more serious, people begin to pay attention to the influence of the air quality in the living environment and the working environment, particularly the environment, on the personal health, meanwhile, various countries also make regulations on the indoor air quality control, and put forward a corresponding control strategy for the indoor air pollution problem. And thus the demand for air measuring instruments or devices is increasing.

In addition, the long-term/regular monitoring devices can help a user to understand and improve the physical health and strength, and the life span of the user is prolonged by reducing the risk of diseases and infections by observing abnormal symptoms of the body through long-term/regular monitoring after preventive measures or early healing.

The traditional air measurement and health condition instruments are of two major types, the first type is a research type instrument with large volume, and the second type is a portable monitor. The first type of measuring instrument has high measuring accuracy, but is expensive, complex to operate and only suitable for trained technicians. For the second kind of measuring instruments, the volume is small because the sensors are generally configured only for a single demand parameter, but the accuracy of the measurement result is often low because different parameters are correlated and influenced by each other, such as measurement only by the configured limited sensors.

For matching needs, there are also simple monitoring devices using different kinds and different sensors, because different sensors have different electronic circuit and voltage requirements, such as the electronic circuit requirements of analog signals, analog digital signals and digital signals, some require 3-volt regulated power supply, some require 5-volt regulated power supply, some require 12-volt regulated power supply, some sensors are affected by heat, and some need to be preheated for operation, for example, when organic compounds in air are equivalent, the sensor or sensor probe needs to be preheated for some time to enable the sensor to operate normally. Further, some sensors may be required to provide stable heat to enable the sensors to operate normally, for example, some sensors measuring dust level may utilize stable heat to cause air convection, and then utilize the light scattering principle to measure the dust concentration.

Generally, different types and different sensors are utilized, and when a heating type sensor which operates by using a thermodynamic principle is involved or monitoring equipment for storing data and analyzing the data is equipped, the heating type sensor is difficult to be matched with a light mobile power supply to operate. Because the sensors and data storage can be maintained for long-term measurement and analysis only by providing a mobile power supply with a large capacity, the user using the mobile power supply with the large capacity is difficult to carry conveniently, and on the contrary, the user using the mobile power supply with a light weight and a small capacity needs to frequently charge or replace the power supply, and no matter the mobile power supply with the large capacity or the mobile power supply with the small capacity is used, the user is inconvenient, and the user easily loses patience use, so that the significance of the monitoring equipment is lost, and the user can hardly talk about carrying the monitoring equipment to carry out personal data measurement.

For example, the portable personal environmental parameter measuring device further includes at least one central processing unit, for example, the central processing unit includes a processing chip, and specifically, the portable personal environmental parameter measuring device includes a central processing unit, and the central processing unit is configured to process the detection data of the heat-generating sensor and the detection data of the non-heat-generating sensor, and perform correlation processing on the detection data of the heat-generating sensor and the detection data of the non-heat-generating sensor, and output the correlation processing, so that a user can timely and accurately acquire the detection data.

For example, the portable personal environmental parameter measuring device further comprises a central processing unit for performing analysis; when the heat-generating sensor measures data, the operation mode of the heat-generating sensor is changed, so that the data in a partial interval is not measured; the analysis includes evaluating and/or predicting the unmeasured partial data based on a correlation between the plurality of environmental parameter level data and storing the evaluated and/or predicted unmeasured partial data in a data storage unit.

For example, the portable personal environmental parameter measuring device processes the detected data through the central processing unit, when the heat-generating sensor starts to work, the operation mode of the heat-generating sensor changes due to the operation mode of the heat-generating sensor being switched from off to on or from pause to on, so that part of the environmental parameters of the heat-generating sensor are not measured during the operation mode switching process, and therefore, the central processing unit is further used for processing the detected data according to the correlation among a plurality of detected data, calculating and obtaining the environmental parameters which are not detected by the heat-generating sensor during the operation mode switching process, and storing the environmental parameters into the storage unit. It should be understood that the environmental parameter is detection data, the detection data obtained through calculation is predicted detection data, and the data missing during the operation mode switching process of the heat-generating sensor is processed through the above process, so that the data is more complete.

In order to enable the user to obtain the detection data accurately in time, in one embodiment, the system further comprises a display unit, and the display unit displays a comprehensive real-time report for the user. For example, the display unit is a display screen, for example, the display screen is connected to the control main board, for example, the display screen is connected to the processing chip through the control main board, the display screen is used for displaying the detection data of the heat-generating sensor and the detection data of the non-heat-generating sensor, and the display screen is also used for displaying a result obtained by performing correlation processing on the detection data by the processing chip, so that the user can timely and accurately acquire the detection data through the display of the display unit on the detection data.

In one embodiment, the portable personal environment parameter measurement device further includes at least one personal mobile device, for example, in this embodiment, the personal mobile device is the second sub-device, and the portable personal environment parameter measurement device is the first sub-device.

The device also comprises at least 2 data transmission modes, so that the portable personal environment parameter measurement device can exchange data with at least one personal mobile device, wherein the at least 2 data transmission modes are data transmission for exchanging data between two different distances, and the at least 2 data transmission modes comprise:

(1) a wireless technology standard of Bluetooth (R) is used to exchange or download a series of more detailed data with the personal mobile device from the portable personal environment parameter measurement device.

(2) By using Near Field Communication (Near Field Communication) component and short-distance high frequency wireless Communication technology, non-contact point-to-point data transmission is carried out, or more precise data is downloaded from the portable personal environment parameter measurement device.

The portable personal environment parameter measuring device is provided with the portable power supply device, namely a first power supply device, wherein the first power supply device supplies electric energy to each sensor to enable each sensor to operate, and if the power supply of the first power supply device is exhausted, a battery can be replaced or the electric quantity of the first power supply device can be supplemented in a charging mode; the portable personal environment parameter measuring device is also provided with an additional portable power supply device power supply which is a second power supply device, the additional portable power supply device power supply does not provide electric energy for the sensor, only provides electric energy for the central processing unit, namely only supports the time marking (time keeping) of the central processing unit, and updates the time value due to the continuous change of the time value. That is, the second power supply device is used for independently supplying power to the central processing unit, so that the central processing unit can still normally work after the first power supply device is powered off, and the time parameter is acquired.

When the portable personal environment parameter measuring device exchanges data with the personal mobile device in a wireless or wired mode for the first time, after the time mark is started, when the power supply of the first power supply device is exhausted, the central processing unit of the portable personal environment parameter measuring device still utilizes the second power supply device to calculate the time value, so that the time mark cannot be stopped to be updated due to the exhaustion of the power supply of the first power supply device, and the second power supply device cannot be used as an operation related sensor. Then, if the user replaces the first power device battery or charges it, the sensor will continue to operate, and the data measured by the sensor will be matched with the time value. Even if no data exchange is carried out in a wireless or wired mode before the power supply of the portable power supply device is exhausted, the data measured by the sensor are continuously updated by the second power supply device, and the continuously updated time value is matched. That is to say, after the electric quantity of the first power supply device is consumed and before the battery is replaced, the central processing unit continuously works under the power supply of the second power supply device, so that the central processing unit can continuously and accurately acquire time without interruption, and therefore, after the first power supply device is fully charged or replaced and each sensor works, the central processing unit matches time parameters for each detected data after acquiring the detected data of each sensor, and further each detected data can have matched time parameters.

At least one advantage of the present invention is to address the deficiencies of current environmental monitoring health monitoring systems and methods.

The user does not need to frequently charge or replace the power supply, and the sensors and data storage of the monitoring equipment can be maintained for long-term continuous measurement and analysis.

The invention can be carried by the user conveniently, and the monitoring equipment has light volume and cannot prevent the daily life of the user.

The present invention also reduces the amount of work on the operator during sampling, data measurement, and analysis, yet preserves the comprehensiveness and generalization of different data metrics. When the sensor in the monitoring equipment is used for sampling data or measuring data, the time interval of measuring data of the heating sensor can be flexibly changed, the changes are automatically carried out, the complexity of data measurement and analysis is not increased, the requirement on data storage capacity is reduced, the electric quantity consumption of the mobile power supply can be automatically and greatly reduced, the time for operating the monitoring equipment can be prolonged by several times to hundreds of times, and the rechargeable mobile power supply can be replaced by a solar battery or a solar rechargeable battery because the electric quantity is low, so that the device does not need to be replaced by the battery or charged permanently.

In one embodiment, a portable personal environment parameter measuring device includes a heat-generating sensor: a heat-generating sensor (respirable suspended particle PM2.5 sensor) for measuring respirable suspended particles PM2.5 in the air; the heat-generating sensor of the inhalable suspended particles PM2.5 has the power consumption of 90mA per hour, and needs to be preheated for 1 minute to accurately measure data, the operation principle of the heat-generating sensor of the inhalable suspended particles PM2.5 is to utilize heat to cause air convection, and then utilize the light scattering principle to measure the dust concentration, the portable personal environment parameter measuring device is also provided with a small-sized mobile power supply and a mobile power supply capacity of 1600mAH, if the time interval of the portable personal environment parameter measuring device (hereinafter referred to as the device) for measuring the PM2.5 is one minute, namely, the time interval of measuring the inhalable suspended particles PM2.5 is one minute, and when the method for adjusting the measuring time interval of the heat-generating sensor provided by the invention is not applied, namely, when the heat-generating sensor is not triggered by the detection data of a non-heat-generating sensor, the heat-generating sensor of the inhalable suspended particles PM2.5 of the device can only continuously maintain the operation for 17.77 hours (1600H minus 90 mAH), in the calculation process, the power consumption of other elements is not counted, and if the power consumption of other elements is calculated, the operation time is shorter than 17.77 hours. If a method according to the present invention (as described in the second embodiment below) is applied, i.e., the operation mode of the heat-generating sensor is changed according to the change of the data measured by one or more other non-heat-generating sensors, there is a different effect.

In a second embodiment, the portable personal environmental parameter measuring device comprises a heat-generating sensor and four non-heat-generating sensors, wherein the heat-generating sensor is the same as the inhalable suspended particles PM2.5 sensor in the first embodiment, and the four non-heat-generating sensors comprise an acceleration sensor, a temperature sensor, a humidity sensor and an illumination intensity sensor (lux sensor).

One non-heat generating sensor may also measure multiple parameters simultaneously, such as the speed sensor measuring the user's range of motion and the device inclination.

Definition and data rating of table-non-heat-generating sensor

(1) And adjusting the time interval of the measurement data of the heating sensor until one measurement data is taken every minute, wherein the heating sensor is preheated for 1 minute before the first measurement data is taken.

(2) # is that if any of the parameters measured by the non-heat generating type sensors does not change from one definition or level to another, the time interval for measuring the data by the heat generating type sensor is adjusted to 17 minutes, the heat generating type sensor is first warmed up for 1 minute, and then 2 measurement data for one minute are taken continuously. Each cycle was 20 minutes.

(3) If the parameter measured by any non-heat generating sensor changes from one definition or level to another, the time interval for measuring data by the heat generating sensor is adjusted to take one measurement data every one minute, and four measurement data are taken successively. Wherein, the heating sensor is preheated for 1 minute before the first measurement is taken.

Table one shows different definitions or levels of the measured data of two non-heat-generating sensors, the light intensity sensor and the acceleration sensor. Description of the drawings: the definition of different changes of the non-heat-generating sensor, and the change of the operation mode of the heat-generating sensor comprises one or more of the following items:

(1) adjusting the time interval of the heat generation sensor measurement data includes lengthening or shortening the time interval of the heat generation sensor measurement data.

(2) Turning on or off the operation of the heat generating sensor.

(3) Adjusting a current or voltage supplied to the heat generating sensor.

For example, if the parameter measured by the non-heat generating sensor does not change from one definition or level to another (except for the definition or level indicated by ". times.") indicating that the parameter measured by the non-heat generating sensor is defined as a steady state, the apparatus adjusts the time interval for measuring the heat generating sensor measurement data to once every 17 minutes by first warming up the heat generating sensor for 1 minute, then taking 2 consecutive one minute measurements, and then turning off the heat generating sensor for 20 minutes each cycle. For example, the user is working in the office for hours, the light intensity sensor measures the user's environment as 750Lux (Lux, lighting units), the range of activity as the second type of small activity (body micro-motion), and the inclination of the device as the second level (10 degrees).

If the parameter measured by any one of the non-heat-generating sensors is changed from one definition or level to another, for example, when the user leaves the office to eat lunch, the acceleration sensor senses that the user's activity range is changed from the second type of small amount of activity (small body movements) to the third type (small movements (slow movements)), the inclination of the device is continuously changed due to the walking relationship, and the light intensity sensor also senses that the user's environment is changed to 2000Lux as measured by the light intensity sensor when the user moves from the office to the outdoor. At this time, the time interval of the measurement data of the heat generating type sensor in the apparatus is adjusted to take one measurement data per one minute and four measurement data in succession based on the change of the data measured by the non-heat generating type sensor, such as the change of the definition or the level caused by the above-mentioned change of the data, wherein the heat generating type sensor is preheated for 1 minute before the first measurement data is taken. Whether the adjusted sampling time interval of the measurement data continues is judged according to the continuous measurement of the non-heat-generating sensors, namely four non-heat-generating sensors in the device.

If the parameter measured by the non-heat-generating sensor belongs to a critical definition or level, as indicated by the index in Table I, from a definition or level, the device adjusts the time interval over which the heat-generating sensor measures data to a denser data measurement time interval, e.g., taking one measurement per minute, wherein the heat-generating sensor is preheated for 1 minute before the first measurement is taken.

The table one shows that the operation mode of the measurement data of the heat-generating sensor is changed by using the definition or level of the parameter measured by the non-heat-generating sensor, or the change of the definition or level of the measured parameter, the non-heat-generating sensor being the acceleration sensor and the light intensity sensor. In addition, the device also comprises other non-heating sensors, such as two non-heating sensors of a temperature sensor and a humidity sensor. Adjusting the operation mode of the heat-generating sensor by using the change of the parameter measured by the non-heat-generating sensor, for example, the change of the temperature sensor and/or the humidity sensor is maintained at + -5%, wherein the parameter measured by the non-heat-generating sensor is defined as a steady state; when the parameter measured by at least one or more of the non-heat-generating sensors is defined as "steady state", the time interval of the measurement data of the heat-generating sensors is adjusted to be measured every 17 minutes by preheating the heat-generating sensors for 1 minute, then taking 2 consecutive measurement data of one minute, and then turning off the heat-generating sensors, each cycle being 20 minutes, until the variation of the data measured by the non-heat-generating sensors exceeds a preset variation range, and the parameter measured by the non-heat-generating sensors (temperature sensors and/or humidity sensors) is defined as "variation state"; for example, when the temperature sensor and/or the humidity sensor in the apparatus is changed by more than ± 5%, and the parameter measured by the temperature sensor and/or the humidity sensor is defined as "change state", the time interval for measuring the data by the heat generating sensor is adjusted to take one measurement data per one minute, and four measurement data are continuously taken, wherein the heat generating sensor is preheated for 1 minute before the first measurement data is taken, and whether the adjusted measurement data sampling time interval continues is judged according to the continuous measurement by the non-heat generating sensors, i.e., the four non-heat generating sensors in the apparatus.

With the portable personal environment parameter measuring device of the second embodiment, since each period of the parameter measured by the heat-generating sensor is 20 minutes under the most stable operation, that is, the time interval for measuring the parameter is 20 minutes, each time the heat-generating sensor operates for 3 minutes (including the preheating time), the operating time per hour becomes only 9 minutes, and compared with the device of the first embodiment, the operating time is extended from 17.77 hours to 118.46 hours.

In the third embodiment, the same heat-generating sensor and non-heat-generating sensor as those of the second embodiment are used, but the heat-generating sensor and the non-heat-generating sensor are provided in different devices. The non-heating sensor is powered by another power supply device except the device.
