Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gas detection, and particularly relates to a portable gas detector. BACKGROUND

[0002] In many industrial environments, laboratories and some special places, the inspection personnel need to work in the space where there may be toxic gases. At the same time, the physical condition (such as blood pressure, heart rate and other basic physical values) of the inspection personnel also has an important influence on the work safety and efficiency.

[0003] The traditional device has many deficiencies. On the one hand, for toxic gas detection, a single gas detector can only detect toxic gases and cannot monitor the physical values of the inspection personnel at the same time. This means that multiple devices need to be used to meet the needs, increasing the burden of the inspection personnel, and the data between different devices cannot be integrated, which is not conducive to the comprehensive evaluation of the working environment and the personnel state. On the other hand, in terms of toxic gas detection, when toxic gas is detected, many devices lack the function of effectively notifying the central control room. This may cause the central control room to not know the danger in time and not be able to take prompt measures such as organizing rescue, adjusting the ventilation system, etc.

[0004] In addition, the inspection personnel may face various complex environmental conditions such as explosion danger, humidity, dust, etc. during the work process. The traditional device may not be perfect in the protection performance (such as explosion-proof, waterproof and dust-proof), and is easy to be damaged, which affects the normal use of the device and the accuracy of the data. Moreover, the power supply and power management of the device also have problems, for example, the battery is not rechargeable or does not have a power monitoring function, which may cause the device to suddenly power off, affecting the continuity of the inspection work.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] As shown in Figure 1 To solve the problems of the prior art, the present application discloses a portable gas detector, which comprises:

[0034] A body value monitoring module is used to monitor the aerobic blood pressure and heart rate value of the inspection personnel. The body value monitoring module comprises a blood pressure sensor and a heart rate sensor. The blood pressure sensor is used to collect blood pressure data, and the heart rate sensor is used to collect heart rate data.

[0035] A toxic gas detection module is used to detect toxic gas in the space. The toxic gas detection module comprises a gas sensor, which can detect a plurality of toxic gases.

[0037] The alarm unit is connected with the data processing unit, and can send an alarm signal when the toxic gas detection module detects that the concentration of toxic gas exceeds a preset threshold;

[0038] The communication unit is connected with the data processing unit, and is used for transmitting the alarm signal and data collected by the body value monitoring module to a central control room.

[0039] The body value monitoring module further comprises a display unit connected with the data processing unit, and used for displaying blood pressure data and heart rate data.

[0040] The gas sensor in the toxic gas detection module is an electrochemical gas sensor or a semiconductor gas sensor.

[0041] The alarm unit comprises a sound alarm and / or a light alarm.

[0042] The communication unit is a wireless communication unit, which adopts one or more of Wi-Fi, Bluetooth, ZigBee or 4G / 5G communication technology.

[0043] The portable gas detector further comprises a power module comprising a rechargeable battery, which is used for supplying power to the body value monitoring module, the toxic gas detection module, the data processing unit, the alarm unit and the communication unit.

[0044] The power module further comprises an electric quantity monitoring unit connected with the rechargeable battery and the data processing unit, which is used for monitoring the electric quantity of the rechargeable battery and transmitting the electric quantity information to the data processing unit, and the data processing unit sends an alarm signal of low electric quantity through the alarm unit when the electric quantity is lower than a preset electric quantity value.

[0045] The shell of the portable gas detector is made of explosion-proof, waterproof and dustproof materials.

[0046] The data processing unit comprises a microprocessor, which is preset with a normal blood pressure range, a normal heart rate range and a toxic gas concentration threshold, and is used for comparing the blood pressure data and the heart rate data with the normal blood pressure range and the normal heart rate range, and comparing the toxic gas detection data with the toxic gas concentration threshold, and controlling the alarm unit to send a corresponding alarm signal when the blood pressure data and the heart rate data are not in the normal range or the toxic gas detection data exceeds the toxic gas concentration threshold.

[0047] The portable gas detector further comprises a storage unit connected with the data processing unit, which is used for storing the blood pressure data, the heart rate data and the toxic gas detection data.

[0048] The working principle of the portable gas detector of the present application is as follows:

[0049] In some embodiments of the present application, the shell of the portable gas detector is in a handheld structure, which is convenient for users to carry. The shell is made of high-strength engineering plastic (such as ABS plastic), which has good explosion-proof, waterproof and dustproof performance. During the manufacturing process of the shell, a sealing design is adopted, and all interfaces and gaps are sealed to prevent dust and moisture from entering the inside of the device. For example, a rubber sealing plug is used at the charging interface to seal the interface when not charging. For explosion-proof performance, the wall thickness and structural design of the shell meet the relevant explosion-proof standards, can withstand a certain range of internal explosion pressure, prevent the flame and fragments generated by the explosion from leaking to the external environment, and ensure safe use in environments with explosion hazards. The inside of the shell is fixedly connected with the above-mentioned multiple functional modules, and data transmission and interaction between the modules are realized through the circuit connection on the printed circuit board (PCB).

[0050] In some embodiments of the present application, the blood pressure sensor adopts an arm type blood pressure sensor, which is installed on one side of the shell. When the user puts the arm into a specific position, the blood pressure sensor can contact the arm and collect blood pressure data. The heart rate sensor adopts an optical heart rate sensor, which is located at the part of the detector shell that contacts the skin of the inspector. The heart rate data is obtained by detecting the reflection change of light caused by the blood flow under the skin.

[0051] In some embodiments of the present application, the display unit adopts a liquid crystal display (LCD), which is connected with the data processing unit through a wire. After processing the received blood pressure data and heart rate data, the data processing unit displays the data in digital form on the LCD screen. The displayed content includes systolic pressure, diastolic pressure and heart rate values, and different display interfaces can be set, such as real-time data display interface and historical data viewing interface.

[0052] In some embodiments of the present application, the gas sensor selects an electrochemical gas sensor, which has high sensitivity to common toxic gases (such as carbon monoxide and hydrogen sulfide). The gas sensor is installed at the front end of the detector, and a special gas inlet is provided to ensure that the gas in the surrounding environment can smoothly enter the sensor for detection. The gas sensor is connected with the data processing unit through an analog signal line, and the detected gas concentration signal is converted into an electrical signal and transmitted to the data processing unit.

[0053] In some embodiments of the present application, the data processing unit adopts a microcontroller (such as an ARM Cortex-M3 core microcontroller) which is internally preset with a normal blood pressure range (for example, systolic pressure 90-139 mmHg, diastolic pressure 60-89 mmHg), a normal heart rate range (60-100 times / minute), and concentration thresholds of different toxic gases (such as a carbon monoxide concentration threshold of 30 ppm). After receiving the blood pressure and heart rate data from the body value monitoring module, the microcontroller compares with the preset range. At the same time, after receiving the gas concentration data from the toxic gas detection module, it is compared with the corresponding concentration threshold. If the data exceeds the normal range or threshold, the microcontroller will send a control signal to the alarm unit.

[0054] In some embodiments of the present application, the sound alarm in the alarm unit adopts a high-decibel buzzer, and the light alarm adopts a high-brightness LED lamp. When the data processing unit determines that an alarm is needed, the microcontroller sends a signal to the buzzer and the LED lamp. For example, when the concentration of toxic gas exceeds the standard, the buzzer emits a continuous alarm sound, and the LED lamp flashes red light; when the blood pressure or heart rate of the inspection personnel is abnormal, the buzzer emits an intermittent alarm sound, and the LED lamp flashes yellow light to distinguish different types of alarm situations.

[0055] In some embodiments of the present application, the communication unit adopts a Wi-Fi module which is connected with the data processing unit through a serial communication port. In a working environment covered by a Wi-Fi network, when an alarm signal is generated or according to a preset time interval (such as every 5 minutes), the data processing unit will package the collected body value monitoring data and toxic gas detection data, and send them to the server in the control room through the Wi-Fi module. If the working environment does not have a Wi-Fi network, it can also be switched to a Bluetooth communication mode, paired with a nearby mobile device (such as a smart phone carried by the inspection personnel), and transmit the data to the phone, and then the phone forwards the data to the control room through the mobile network.

[0056] In some embodiments of the present application, the power module adopts a lithium battery as a rechargeable battery, and its capacity is designed to be 2000 mAh according to the power consumption demand of the device. The lithium battery is connected with an external charging interface through a charging management chip, and the charging interface adopts a general USB-Type-C interface, which is convenient for charging with a common charger.

[0057] In some embodiments of the present application, the power monitoring unit adopts a dedicated power monitoring chip which is connected with the positive and negative electrodes of the lithium battery, and monitors the voltage, current and other parameters of the battery in real time, and converts these parameters into power percentage information and transmits them to the data processing unit. When the power is lower than 20%, the data processing unit triggers the alarm unit to issue an alarm signal for low power.

[0058] The operation and use process of the portable gas detector of the present application is as follows:

[0059] The user presses the power button on the detector to turn it on, and the device performs self-checking. During the self-checking process, each module performs initialization operations, such as calibration of the sensor of the body value monitoring module, search for available networks by the communication unit, etc.

[0060] After turning on, the display unit displays the basic information of the device, such as the device model, power information, etc., and at the same time, the body value monitoring module starts to collect and display the blood pressure and heart rate data of the inspection personnel.

[0061] The user carries the detector into the working area, and the toxic gas detection module starts to detect the concentration of toxic gas in the surrounding environment in real time. During the detection process, the inspection personnel can check the body value and toxic gas concentration data on the display unit at any time.

[0062] If the concentration of toxic gas detected exceeds the preset threshold or the body value is abnormal, the alarm unit immediately sends an alarm signal. The user takes appropriate measures according to the alarm situation, such as wearing protective equipment or evacuating the dangerous area.

[0063] During the detection process, the communication unit transmits data to the control room according to the preset rules. At the same time, the data processing unit stores the collected data in the internal storage unit (such as a flash memory chip). The stored data is arranged in chronological order, which facilitates subsequent query and analysis.

[0064] After the inspection work is completed, the user presses the power button to turn off the device. If the power is low during use, the inspection personnel charges the device using a USB-Type-C charger. During the charging process, the display unit displays the charging progress until the battery is fully charged.

[0065] Finally, it should be noted that the above is only a preferred embodiment of the present application and does not limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the scope of the present application shall be included in the protection scope of the present application.
