Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment, in particular to a combustible gas alarm device and an alarm system. Background Art

[0002] Combustible gas refers to a substance that can be ignited and is in a gaseous state at normal temperature and pressure. Examples include hydrogen, acetylene, ethylene, ammonia, hydrogen sulfide, etc. Combustible gas has the general properties of gas. A combustible gas of one component is called a single gas; a mixture of two or more combustible gases is called a mixed combustible gas. Combustible gases are mixed in a certain proportion in the corresponding combustion-supporting medium and can cause combustion or explosion under the action of an ignition source. Combustible gas is ejected from a nozzle at a certain flow rate, and its combustion rate is determined by the diffusion rate of the combustible gas and air.

[0003] Among household combustible gases, leaks of methane, hydrogen or carbon monoxide are the main sources of fire problems.

[0004] Combustible gas alarms are essential equipment for home safety. They monitor combustible gas in the house in real time to prevent combustible gas poisoning or early fire warnings that cause loss of life and property. Most of the combustible gas alarms in the industry are independent and cannot be connected to each other. Once a carbon monoxide leak or fire occurs, they can only alert people around to escape; a small number of combustible gas alarms can only achieve simple local networking, that is, they can only form a network with external servers through multiple independent combustible gas alarms. This method is costly and cannot respond in time when the accident personnel drink too much or are slightly poisoned, causing loss of life and property. Utility Model Content

[0035] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are 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.

[0036] The utility model aims to solve the problem in the prior art that the combustible gas alarm device is not easy to network or the networking cost is high. Through two independent wireless communication modules, the external detection module and the terminal device server can be quickly networked, which is more economical and reliable. Example 1

[0037] like Figure 1 A combustible gas alarm device shown includes a combustible gas alarm device 1 and a detection module 10 arranged in different rooms or spaces. In particular, the combustible gas alarm device 1 is provided with two independently arranged communication modules, namely a first communication module 4 and a second communication module 5.

[0038] In this embodiment, the detection module 10 includes a combustible gas detection device 3 for monitoring the concentration of combustible gas in a specified area, a smoke detection device 11 for monitoring the smoke concentration in the specified area, and a temperature detection device 12 for monitoring the ambient temperature in the specified area.

[0039] It should be noted that the combustible gas alarm device 1 and the combustible gas detection device 3 are two different devices. The combustible gas alarm device 1 is the main device body. On the premise that it can realize the functions of the alarm device itself, it also has multiple communication modules to realize system networking and interconnection. And the alarm signal is sent to the remote server 7 for storage and pushed to the terminal device 13 for remote alarm. The combustible gas detection device 3 only has detection function and communication function, that is, when the combustible gas concentration in the area reaches the monitoring threshold, the combustible gas detection device 3 will transmit the alarm signal to the combustible gas alarm device 1 for alarm feedback.

[0040] In this embodiment, the first communication module 4 is used to communicate with the detection module 10, and the first communication module 4 adopts a 433 wireless radio frequency communication module. The 433 communication has the advantages of long transmission distance, strong penetration, and high stability, and the cost is much lower than Bluetooth and WiFi solutions. It is more suitable for scenarios with less data transmission such as the present invention.

[0041] The second communication module 5 is used to communicate with the remote server and the terminal device 13. The terminal device 13 here includes a mobile communication device and a computer. The combustible gas alarm device 1 transmits data to the remote server through the second communication module 5 for summary storage and synchronous push notification to the mobile phones of the property manager, the fire grid member, the guardian and the individual user for alarm. In particular, in this embodiment, the second communication module 5 adopts a WiFi communication module, which realizes two different channels for communication with the first communication module 4 under the premise of ensuring high economic benefits, greatly reducing signal interference.

[0042] It should be noted that the communication method between the first communication module 4 and the second communication module 5 is not limited to 433 wireless radio frequency communication and WiFi communication. Within a reasonable cost range, ZigBee or Bluetooth communication and the permutations and combinations of these communication methods can also be selected as the first communication module 4; 4G or 5G or NB-IOT module and the permutations and combinations of these communication methods can also be selected as the second communication module 5.

[0043] like Figure 2As shown, the combustible gas alarm device 1 of the utility model further includes a housing 2 and a PCB board 6 disposed in the housing 2, wherein the housing 2 has a cavity for accommodating the PCB board 6, that is, the PCB board 6 is fixed between the two housings 2 by bolts, and the first communication module 4 and the second communication module 5 are also disposed on the PCB by electrical connection. In particular, a lithium battery 9 is also disposed on the PCB board 6 for providing power to the circuit.

[0044] In this embodiment, the combustible gas alarm device 1 also includes a combustible gas sensor 14 and an alarm 8. It should be noted that the difference between the combustible gas sensor 14 and the combustible gas detection device 3 is that the combustible gas sensor 14 is arranged in the combustible gas alarm device 1, and it only has the function of detecting the concentration of combustible gas, but does not have the communication function. That is, the combustible gas sensor 14 is arranged to enable the combustible gas alarm device 1 to have a complete alarm function, while the combustible gas detection device 3 is arranged to expand the monitoring area and monitoring space.

[0045] In particular, a main controller (not shown in the figure) is also welded on the PCB board 6. The main controller is connected to the alarm 8, the first communication module 4, and the second communication module 5 respectively; the main controller is used to receive the alarm signal transmitted by any one of the combustible gas detection device 3, the smoke detection device 11, and the temperature detection device 12 in the detection module through the first communication module 4, and can drive the alarm 8 to send out the alarm information when receiving the alarm signal.

[0046] The alarm 8 is mainly a device such as a buzzer, a speaker, a vibrator, etc. that can send out alarm information by making sounds, vibrating, etc. In this embodiment, a buzzer is used as the alarm 8. This solution is more economical, practical, and has the best effect, and it has a better reminder effect on residents indoors.

[0047] Furthermore, the combustible gas alarm device 1 mentioned in the utility model can be used to monitor carbon monoxide, hydrogen, methane, etc. in the environment, and only the combustible gas detection device 3 and the combustible gas sensor 14 need to be set accordingly. When the combustible alarm sensor 14 detects that the combustible gas concentration reaches a preset threshold, it will also transmit an alarm signal to the main controller, and then the main controller drives the alarm 8 to issue an alarm message, that is, the combustible alarm sensor 14 is electrically connected to the main controller through a line.

[0048] In this embodiment, the combustible gas sensor 14 and the combustible gas detection device 3 respectively use a carbon monoxide sensor and a carbon monoxide detection device to perform environmental monitoring. Example 2

[0049] like Figure 3As shown, the utility model also discloses a combustible gas alarm system, which adopts the combustible gas alarm device 1, the combustible gas detection device 3 and the remote server 7 described in Example 1. In particular, the remote server 7 is used to communicate and interact with the terminal device 13.

[0050] When the combustible gas concentration in the area where the combustible gas detection device 3 is located reaches the monitoring threshold, the alarm signal is transmitted to the combustible gas alarm device 1, and the combustible gas alarm device 1 then transmits the alarm signal to the remote server 7 for storage and pushes it to the terminal device 13 user for alarm.

[0051] Furthermore, two independent communication modules are provided in the flammability alarm device, namely the first communication module 4 and the second communication module 5 mentioned in Example 1. The two communication modules use two independent channels for data communication, that is, the first communication module 4 can use a 433 wireless radio frequency communication module or a ZigBee communication module or a Bluetooth communication module, and the second communication module 5 can use a 4G communication module or a 5G communication module or a WIFi communication module or a NB-IOT module.

[0052] The first communication module 4 is used for wireless communication connection with the combustible gas detection device 3, and the second communication module 5 is used for wireless communication connection with the remote server 7. The user can select the first communication module 4 and the second communication module 5 according to actual needs. In this embodiment, the first communication module 4 can adopt a 433 wireless radio frequency communication module, and the second communication module 5 adopts a NB-IOT wireless communication module. Example 3

[0053] like Figure 4 As shown, this embodiment discloses a combustible gas alarm system, which adopts the combustible gas alarm device 1 described in Example 1, multiple combustible gas detection devices 3, multiple smoke detection devices 11, multiple temperature detection devices 12 and a remote server 7. In particular, the remote server 7 is used to communicate and interact with a terminal device 13.

[0054] When the combustible gas concentration in the area where the combustible gas detection device 3 is located reaches the monitoring threshold, the alarm signal is transmitted to the combustible gas alarm device 1, and the combustible gas alarm device 1 then transmits the alarm signal to the remote server 7 for storage and pushes it to the terminal device 13 user for alarm.

[0055] Furthermore, two independent communication modules are provided in the flammability alarm device, namely the first communication module 4 and the second communication module 5 mentioned in Example 1. The two communication modules use two independent channels for data communication, that is, the first communication module 4 can use a 433 wireless radio frequency communication module or a ZigBee communication module or a Bluetooth communication module, and the second communication module 5 can use a 4G communication module or a 5G communication module or a WIFi communication module or a NB-IOT module.

[0056] The first communication module 4 is used to wirelessly connect to the combustible gas detection device 3, the smoke detection device 11, and the temperature detection device 12, and the second communication module 5 is used to wirelessly connect to the remote server 7. The user can select the first communication module 4 and the second communication module 5 according to actual needs. In this embodiment, the first communication module 4 can adopt a 433 wireless radio frequency communication module, and the second communication module 5 can adopt a NB-IOT wireless communication module.

[0057] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary personnel in the field to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents of the present invention for protection have been fully recorded in the claims.
