Embodiment approach 1

[0054] Embodiment 1: Ventilation measures are used to ventilate and replace the gas in the limited space before operation. The operators and guardians take out the wristband, remove the gas sensing hole cover 3, and turn on the device through the functional control element 901 in the control element 9. Set the receiver and sender modes for pairing. Use a spreader to put the gas detection bracelet at the sending end into a limited space to detect the gas. After the test is passed, the operator wears the bracelet and enters the limited space to work, and the guardian wears the bracelet and stays outside the place to pay attention at all times. When the test fails , continue to perform ventilation replacement until the gas detection is qualified.

Embodiment approach 2

[0055] Embodiment 2: When the operator wears a gas detection bracelet to work in a limited space, the gas detection bracelet at the sending end maintains a normal working state, and the micro control unit MCU4 controls the gas sensor 12 to monitor and analyze the surrounding air, and the gas content value Displayed on the LCD screen 10, when the toxic and harmful gas in the surrounding environment exceeds the standard, the micro control unit MCU4 sends a signal to the speaker element 702 and the LED element 8 after receiving the data information from the gas sensor 12, and the vibration element 11 vibrates at the same time, and the gas detection at the sending end The wristband reminds the workers of the danger of the surrounding environment through sound, light, and vibration; the gas micro-control unit MCU4 of the gas detection bracelet at the sending end controls the Bluetooth component 6 to send data information to the gas detection bracelet at the receiving end, and the rec...

Embodiment approach 3

[0056] Embodiment 3: When an operator wears a gas detection bracelet to carry out operations in a limited space, the gas detection bracelet at the sending end maintains a normal working state, and the micro control unit MCU4 controls the heart rate monitoring element 13 to monitor the wearer's heart rate, and the heart rate Displayed on the liquid crystal screen 10, when the ambient temperature is too high or too low or the operator's physical reasons cause the heart rate to be too high or too low, the micro control unit MCU4 receives the data information of the heart rate monitoring element 13 and then sends a message to the speaker element 702 and the LED element 8 to send a signal, the vibration element 11 vibrates at the same time, and at the same time the gas micro-control unit MCU4 of the gas detection bracelet at the sending end controls the Bluetooth element 6 to send data information to the gas detection bracelet at the receiving end, and the receiving end displays it t...

Abstract

The invention discloses a poisonous and harmful gas monitoring device of a limited space. The gas monitoring device is in a way that a worker gas detection bracelet and a monitor gas detection bracelet are paired, wherein each gas detection bracelet comprises a bracelet main body (1), a ring belt (2) and a gas induction hole cover piece (3), and a micro control unit MCU (4), a power supply component (5), a Bluetooth component (6), a voice component (7), an LED component (8), a control component (9), a liquid crystal screen (10), a shock component (11), a gas sensor (12) and a heart rate monitoring component (13) are arranged in the bracelet main body (1). Before operation of the limited space, a worker and a monitor take out the gas detection bracelet, startup is performed by the control component (9) and receiving and emission modes are set for pairing, the worker wears the bracelet at hand and enters the limited space for operation, and the monitor wears the bracelet to monitor outside the limited space. By the gas monitoring device, the safety of the worker is improved, the problems of blind rescue and portability are solved, and the gas monitoring device has high practicability.

Description

technical field [0001] The invention belongs to the technical field of toxic and harmful gas monitoring, and in particular relates to a toxic and harmful gas monitoring device in a limited space. Background technique [0002] Confined space refers to a space that is closed or partially closed, with narrow and limited entrances and exits, not designed as a fixed workplace, poor natural ventilation, and prone to accumulation of toxic and harmful, flammable and explosive substances, or insufficient oxygen content. The limited space is divided into three categories: (1) Airtight equipment: such as cabins, storage tanks, vehicle-mounted tanks, reaction towers (kettles), refrigerators, pressure vessels, pipelines, flues, boilers, etc.; (2) Underground limited space: Such as underground pipelines, basements, underground warehouses, underground projects, underground ditches, tunnels, culverts, pits, waste wells, cellars, sewage pools (wells), biogas tanks, septic tanks, sewers, etc....
