Description

Technical Field

[0001] The utility model belongs to the technical direction of gas detection, and specifically relates to a wireless low-power consumption gas detector based on LoRa. Background Art

[0002] A gas detector is an instrument tool for detecting gas leakage concentration, including: portable gas detector, handheld gas detector, fixed gas detector, online gas detector, etc. It mainly uses gas sensors to detect the types of gases in the environment. Gas sensors are sensors used to detect the composition and content of gases. It is generally believed that the definition of gas sensors is based on the detection target. All sensors used to detect gas composition and concentration are called gas sensors, regardless of whether they use physical or chemical methods. For example, sensors that detect gas flow are not considered gas sensors, but thermal conductivity gas analyzers are important gas sensors, although they sometimes use roughly the same detection principles.

[0003] The existing devices are generally installed directly on the walls of the production workshops, which often cause wear and tear on the walls during subsequent disassembly and maintenance, affecting the aesthetics. In addition, the installation process is cumbersome, the disassembly and assembly time is long, and a lot of wall debris is generated. The subsequent cleaning costs of the factory cannot be reduced. During daily use, a lot of dust will accumulate, which is not conducive to observation by staff. During use, the dependence on power supply is high, the wiring time during installation is long, and the installation process is cumbersome. Utility Model Content

[0017] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3The utility model provides a technical solution: a wireless low-power gas detector based on LoRa, comprising a gas detector 1, which is placed in a production workshop. Four sets of fixed suction cups 5 are fixedly installed on one side of the gas detector 1 for adsorbing on the wall of the production workshop, which plays a role of rapid disassembly and assembly, and can be installed without loss, reducing the construction waste generated during installation. A display screen is arranged on the other side of the gas detector 1, which is convenient for the staff to observe the gas detection data. A LoRa wireless communication module 2 is fixedly installed on one end of the gas detector 1. The LoRa wireless communication module 2 uses spread spectrum technology to achieve a balance between distance and power consumption, and can achieve a communication distance of hundreds of meters to several kilometers. The staff can receive the data of the gas detector 1 at a long distance without frequently entering the production workshop to check, which effectively improves the detection efficiency and reduces the burden on the staff. A battery 3 is fixedly installed on the other end of the gas detector 1. The battery 3 is used to make the gas detector 1 work normally in a scenario where the power supply cannot be connected, thereby expanding the use range of the equipment. A low-power gas detection module 4 is fixedly installed on one side of the battery 3. The low-power gas detection module 4 is used to reduce the power consumption of the gas detector 1, improve the endurance of the gas detector 1, and extend the service life;

[0019] A communication antenna 21 is also fixedly mounted on one side of the gas detector 1 , and the communication antenna 21 is connected to the LoRa wireless communication module 2 for transmitting gas detection signals.

[0020] In this embodiment:

[0021] When the staff needs to detect the gas in the production workshop, the staff first holds the gas detector 1, installs the battery 3 on the gas detector 1, and then presses the four sets of fixed suction cups 5 on the gas detector 1 toward the wall of the production workshop. At this time, the four sets of fixed suction cups 5 are adsorbed on the wall of the production workshop, and the gas detector 1 is fixed. Then the staff controls the LoRa wireless communication module 2 to start through the display screen on the gas detector 1, and sends the signal to the staff's computer through the communication antenna 21. After the setting is completed, the staff can leave the production workshop and go to the control room to perform centralized detection through the computer, without having to stay in the production workshop for a long time;

[0022] By using the battery 3 in conjunction with the gas detector 1, it can work normally in scenarios where power cannot be accessed, effectively expanding the use range of the gas detector 1 and reducing dependence on the power cord. By using the LoRa wireless communication module 2 in conjunction with the communication antenna 21, data transmission can be performed without wiring, effectively reducing the time required for installation, which is convenient and fast, and can achieve a communication distance of hundreds of meters to several kilometers. There is no need for staff to stay in the production workshop for a long time, reducing the impact of workshop noise on staff. By using the low-power gas detection module 4, the power consumption of the gas detector 1 can be reduced, and the battery life can be improved.
