[0014] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0015] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0016] In an exemplary embodiment, a gas alarm device is provided, wherein a plurality of alarm points are arranged on the gas alarm device, and each alarm point is provided with a corresponding alarm threshold (an empirical safety value set artificially), a return difference, and an alarm mode. The alarm mode includes a first alarm mode and a second alarm mode, wherein the first alarm mode is to alarm when the real-time measurement data is greater than or equal to the alarm threshold, and the second alarm mode is to alarm when the real-time measurement data is less than or equal to the alarm threshold. Each alarm point alarms according to the corresponding alarm threshold and alarm mode. Two adjacent alarm points determine the alarm interval according to the corresponding alarm threshold, return difference, and alarm mode, and alarm.

[0017] For example: set the alarm point A1 of the gas alarm device: alarm threshold V1, return difference R1 and alarm mode M1; Set the alarm point A2 of the gas alarm device: alarm threshold V2, return difference R2 and alarm mode M2; Set the alarm point A3 of the gas alarm device: alarm threshold V3, return difference R3 and alarm mode M3; … Set the alarm point A of the gas alarm device n : Alarm threshold V n , return difference R n and alarm mode M n .

[0018] The gas alarm device converts the gas sensor value into real-time measurement data for display to the user through internal analog-to-digital conversion. This real-time measurement data is compared with the alarm threshold of each alarm point. When it exceeds or falls below the alarm threshold, the gas alarm device prompts an alarm to remind personnel to pay attention to safety.

[0019] For two adjacent alarm points, the intersection or union of the alarm thresholds is automatically taken according to their alarm modes, and then the corresponding alarm logic is executed in the corresponding interval.

[0020] The return difference is used to prevent the gas alarm from jumping back and forth near the alarm threshold and switching between the alarm state and the non-alarm state repeatedly at a high frequency. This value is used in conjunction with the alarm threshold to determine whether the gas alarm device will exit the alarm state.

[0021] For the above-mentioned gas alarm device, in an exemplary embodiment, as Figure 1 As shown, an alarm method for a gas alarm device is provided, comprising the following steps.

[0022] S1: Get the actual measurement data of the gas.

[0023] S2: For the real-time measurement data, each alarm point generates an alarm according to the corresponding alarm threshold and alarm mode.

[0024] When the alarm mode of the alarm point is the first alarm mode, an alarm is triggered when the real-time measurement data is greater than or equal to the alarm threshold; when the alarm mode of the alarm point is the second alarm mode, an alarm is triggered when the real-time measurement data is less than or equal to the alarm threshold.

[0025] S3: For the real-time measurement data, two adjacent alarm points determine an alarm interval according to the corresponding alarm threshold, return difference and alarm mode, and issue an alarm. The alarm interval includes an interval for entering the alarm and an interval for exiting the alarm. The two adjacent alarm points are the first alarm point and the second alarm point.

[0026] Step S3 specifically includes: according to the alarm mode, obtaining the intersection or union of the alarm thresholds of two adjacent alarm points (such as Figure 2 As shown); determining an interval for entering the alarm according to the intersection or the union; determining an interval for exiting the alarm according to the intersection and the return difference, or determining an interval for exiting the alarm according to the union and the return difference.

[0027] Specific: 1) First alarm point A x : The alarm threshold is V x , the return difference is R x , alarm mode M x For the first alarm mode, x=1,2,3...,n-1.

[0032] 2) First alarm point A x : The alarm threshold is V x , the return difference is R x , alarm mode M x It is the second alarm mode.

[0033] Second alarm point A x+1 : The alarm threshold is V x+1 , the return difference is R x+1 , alarm mode M x+1 It is the second alarm mode.

[0034] The union of the two is V. x+1 .

[0035] The alarm interval is less than V x+1 , that is, when V r <V x+1 Alarm when.

[0036] The interval for exiting the alarm is greater than V x+1 +R x+1 , that is, when V r >V x+1 +R x+1 Exit alarm.

[0037] 3) First alarm point A x : The alarm threshold is V x , the return difference is R x , alarm mode M x It is the second alarm mode.

[0038] Second alarm point A x+1 : The alarm threshold is V x+1 , the return difference is R x+1 , alarm mode M x+1 It is the first alarm mode.

[0039] The union of the two is V x and V x+1 .

[0040] The alarm interval is less than V x and greater than V x+1 , that is, when V r <V x , or V r >V x+1 Alarm when The interval for exiting the alarm is greater than V x +R x and less than V x+1 –R x+1 , that is, when V r >V x +R x , or V r <V x+1 –R x+1 Exit alarm.

[0041] 4) First alarm point A x The alarm threshold is V x , the return difference is R x , alarm mode M x It is the first alarm mode.

[0042] Second alarm point A x+1 The alarm threshold is V x+1 , the return difference is R x+1 , alarm mode M x+1 It is the second alarm mode.

[0043] The intersection of the two is V x and V x+1 .

[0044] The alarm interval is greater than V x and less than V x+1 , that is, when V r >V x , or V r <Vx+1 Alarm when The interval for exiting the alarm is less than V x -R x and greater than V x+1 +R x+1 , that is, when V r <V x -R x , or V r >V x+1 +R x+1 Exit alarm.

[0045] According to the above settings of alarm mode, alarm threshold and return difference, the corresponding alarm interval is counted, and then the alarm is output within the alarm interval.
