Problems solved by technology

Portable alarms have the advantages of small size and weight, low energy consumption, and easy to carry, but like fixed gas alarms, they can only realize detection and alarm functions locally, and cannot instantly transmit on-site gas information to remote locations.
[0003] When the staff arrives at the environmental site with a traditional alarm device, if the concentration of flammable gas, toxic gas, or harmful gas exceeds the limit, the traditional alarm device will send out alarm signals such as sound, light, vibration, etc., and the staff is in this dangerous gas environment. In the face of serious life danger, it is possible that the on-site information cannot be transmitted to other staff in real time, resulting in the interruption of information transmission, while other staff cannot get the on-site information in real time, causing more staff to enter the dangerous area, seriously increasing the related The danger of personnel's work cannot meet people's increasing demand for safe production

Embodiment 1

[0024] As shown in Figure 1, a portable gas alarm system with wireless communication function includes a gas detection terminal and an information processing device.

[0025] In this embodiment, the gas detection terminal is a portable gas detection terminal, which can be fixedly installed on the detection site or carried by the staff. Its structure diagram is as follows figure 1 As shown, it includes a main housing, a gas sensor, a battery detection module, a central processing unit, a signal conversion module connected to the central processing unit, a control module, a power supply module, a display module and a parameter setting module arranged inside the main housing, The battery detection module is connected with the power module.

[0026] In addition, a wireless data sending device and an antenna connected to the central processing unit are also arranged inside the main casing for sending the detected information to the outside. The inside of the main housing is also p...

Embodiment 2

[0035] The structure of a portable gas alarm system with wireless communication function in this embodiment is basically the same as the structure of Embodiment 1, and the circuit connection diagram is also the same, the difference is that the antenna of the portable gas detection terminal is installed outside the housing, and is located in shell top.

[0036] The working principle of the system in this embodiment is the same as that in Embodiment 1.

The gas detecting terminal is provided with a wireless data transmitting device and a wireless data transmitting antenna, and the information processing device is provided with a central processing unit, a power supply, a control module and a wireless data receiving device, wherein the power supply, the control module and the wireless data receiving device are connected with the central processing unit, and the wireless data transmitting device is used with the wireless data receiving device. The portable gas alarm system is used for wirelessly transmitting on-site gas monitoring data to a specified remote wireless receiving device to realize remote gas monitoring function.

Description

technical field [0001] The invention relates to a gas alarm system, in particular to a portable gas alarm system with wireless communication function, which belongs to the technical field of alarm control. Background technique [0002] With the advancement of science and technology, the safety alarm technology for flammable gas, toxic gas and harmful gas in the production process has been widely developed and applied. Gas alarm systems are widely used in petroleum, chemical industry, metallurgy, mining and other fields, but traditional gas alarm systems have limitations. At present, gas alarm instruments can be divided into two types: fixed and portable, which are usually composed of data acquisition circuits, central processing circuits, and alarm control circuits. Portable alarms have the advantages of small size and weight, low energy consumption, and easy to carry. However, like fixed gas alarms, they can only achieve local detection and alarm functions, and cannot inst...
