[0026] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0027] In the smoke sensing module, since there are manufacturing tolerances in the light sensing element and the light emitting element inside the smoke sensing module, the smoke sensing module needs to be calibrated before leaving the factory, that is, the measurement value of the smoke sensing module needs to be corrected or calibrated by a calibration coefficient. At present, the calibration of the smoke sensing module is mostly in a manual calibration mode, which has problems such as long calibration time, low calibration efficiency and being easily affected by human factors. Based on this, the embodiments of the present application provide a smoke sensing module calibration method, device, equipment and storage medium, which can solve the technical problem.
[0028] In order to facilitate the description of the smoke sensing module calibration method of the embodiments of the present application, the application scenario corresponding to the embodiments of the present application will be described first.
[0029] Referring to Figure 1 the application scenario schematic diagram of the smoke sensing module calibration method, the application scenario includes a smoke box, a calibration equipment and a smoke sensing module, wherein the calibration equipment is in communication connection with the smoke box, the smoke sensing module is arranged in the smoke box, and the smoke box includes a smoke generating module, a smoke measuring module, a smoke circulating module, an exhaust module, an opening and closing door module and a communication module.
[0030] The calibration device can also be referred to as a calibration tool, which mainly communicates with the smoke box through a Modbus serial communication protocol. The calibration device can be composed of an embedded main control board card, or can be composed of an electronic device including a processor and a memory. The calibration device communicates with the communication module in the smoke box to realize the interaction of data and instructions between the calibration device and each module in the smoke box; at the same time, the calibration device can also communicate with the smoke sensing module to realize the functions of sending commands to the smoke sensing module and obtaining the parameter values of the smoke sensing module.
[0031] The functions of each module included in the smoke box are as follows: The smoke generating module is mainly used to generate smoke in the smoke box.
[0032] The smoke exhaust module is mainly used to exhaust the smoke in the smoke box.
[0033] The smoke circulation module is mainly used to circulate the smoke in the smoke box, so that the smoke is evenly distributed in the smoke box.
[0034] The door opening and closing module is mainly used to open or close the door of the smoke box, and automatically extend the platform for fixing the base of the smoke sensing module when the door of the smoke box is opened, so as to facilitate manual disassembly and installation of the smoke sensing module, i.e. installing the smoke sensing module in the smoke box or disassembling the smoke sensing module from the smoke box.
[0035] The smoke measurement module is mainly used to measure the smoke concentration in the smoke box in real time.
[0036] The communication module is mainly used to communicate with the calibration device using the Modbus protocol, and send the data or instructions sent by the calibration device to the main control module of the smoke box, so that the main control module of the smoke box controls the corresponding module to perform the corresponding operation, or directly sends the data or instructions sent by the calibration device to the corresponding module in the smoke box to perform the corresponding operation.
[0037] It should be noted that the execution subject of the embodiment of the present application can be the calibration device described above, or can be a smoke sensing module calibration device, or can be the entire system including the calibration device and the smoke box, or can be other devices or apparatuses, which are not limited here. The following embodiments will take the smoke sensing module calibration method of the embodiment of the present application applied to the calibration device as an example, i.e. taking the calibration device as an execution subject to illustrate the method of the embodiment of the present application.
[0038] Figure 2 is one of the flowcharts of the smoke sensing module calibration method provided by the present application, as shown in Figure 2 The method comprises the following steps: In step 202, the smoke generation module is controlled to generate smoke in the smoke box, and the smoke measurement module is controlled to measure the smoke concentration in the smoke box and send the measured smoke concentration in the smoke box to the calibration device.
[0039] Before the smoke sensing module is calibrated, an initialization operation can be performed first. The initialization operation mainly includes that the calibration device controls the opening and closing door module in the smoke box to open the smoke box door and automatically extend the platform for fixing the smoke sensing module base, then the single calibration smoke sensing module is installed in the smoke box, and after detecting that the installation of the smoke sensing module is completed, the opening and closing door module is controlled to retract the platform for fixing the smoke sensing module base and close the smoke box door. Here, the single calibration smoke sensing module can be one or more. In the embodiment, the single calibration smoke sensing module can be selected as 6-8, so that the calibration accuracy can be considered and the calibration efficiency can be improved. If batch calibration of the smoke sensing module is required, the steps can be executed in a loop to achieve the batch calibration.
[0040] It can be understood that before the smoke sensing module is calibrated, there is no smoke in the smoke box. After the single calibration smoke sensing module is installed in the smoke box, the calibration device can send a smoke generation control instruction to the smoke generation module in the smoke box. After receiving the smoke generation control instruction, the smoke generation module can automatically generate smoke in the smoke box. At the same time, the calibration device can also send a smoke measurement control instruction to the smoke measurement module in the smoke box. After receiving the smoke measurement control instruction, the smoke measurement module can measure the real-time smoke concentration in the smoke box and send the measured smoke concentration to the calibration device in real time through the Modbus protocol.
[0041] In step 204, if it is determined that the smoke concentration measured by the smoke measurement module reaches the preset calibration range, the smoke concentration reaching the preset calibration range is determined as the first smoke concentration, and a calibration instruction is sent to the smoke sensing module. The calibration instruction includes the first smoke concentration, which is used to instruct the smoke sensing module to determine the calibration coefficient based on the first smoke concentration and the second smoke concentration detected by the smoke sensing module, and to calibrate the smoke sensing module based on the calibration coefficient.
[0042] In this step, after obtaining the smoke concentration sent by the smoke measurement module in real time, the calibration device can continuously judge the smoke concentration measured by the smoke measurement module. Specifically, it can be judged whether the smoke concentration measured by the smoke measurement module reaches the preset calibration range. The preset calibration range can be a pre-set smoke concentration range, in which the calibration of the smoke sensing module can be more accurately realized.
[0043] In a possible implementation, if it is determined that the smoke concentration measured by the smoke measurement module does not reach the preset calibration range, the calibration device can control the smoke generation module to continue generating smoke in the smoke box (i.e., to increase the smoke concentration in the smoke box) and control the smoke circulation module to circulate the smoke in the smoke box, so that the smoke generated in the smoke box is uniformly distributed in the smoke box. Here, by continuously increasing the smoke concentration in the smoke box when the smoke concentration in the smoke box does not reach the preset calibration range, the smoke concentration in the smoke box can be controlled in real time, thereby improving the accuracy of subsequent calibration of the smoke sensing module. By circulating the smoke through the smoke circulation module, the smoke concentration in the smoke box can be made more uniform to improve the subsequent calibration effect, and the smoke concentration measured by the smoke measurement module can be quickly brought to the preset calibration range.
[0044] In another possible implementation, if it is determined that the smoke concentration measured by the smoke measurement module reaches the preset calibration range, the smoke concentration measured by the smoke measurement module and reaching the preset calibration range is taken as a first smoke concentration. The first smoke concentration is then encapsulated in the calibration instruction and sent to each smoke sensing module. After receiving the calibration instruction, each smoke sensing module can parse the first smoke concentration therefrom, and can also obtain the smoke concentration in the smoke box detected by the smoke sensing module at the moment, denoted as a second smoke concentration (the second smoke concentration is an uncalibrated smoke concentration). Then, each smoke sensing module can divide the first smoke concentration by the second smoke concentration, and the obtained ratio can be taken as a calibration coefficient r of the smoke sensing module. After the smoke sensing module subsequently detects a smoke concentration, the detected smoke concentration can be multiplied by the calibration coefficient to obtain a calibrated smoke concentration, i.e., an actual smoke concentration.
[0045] Step 206, after the smoke sensing module is calibrated according to the calibration instruction, the calibration coefficient and a third smoke concentration sent by the smoke sensing module are obtained, and it is determined whether the smoke sensing module is successfully calibrated according to the calibration coefficient and the third smoke concentration. The third smoke concentration is a smoke concentration obtained by the smoke sensing module after calibrating a currently detected smoke concentration based on the calibration coefficient.
[0046] In this step, after the calibration device sends the calibration instruction to each smoke sensing module, the calibration device can continue to send a parameter acquisition instruction to each smoke sensing module, where the parameter acquisition instruction is used to acquire the calibration coefficient determined by each smoke sensing module and the smoke concentration calibrated by each smoke sensing module based on the calibration coefficient.
[0047] After each smoke sensing module calculates the calibration coefficient, it can be considered that the smoke sensing module is calibrated based on the calibration instruction. Subsequently, after each smoke sensing module receives the parameter acquisition instruction of the calibration device, it can send its corresponding calibration coefficient and the smoke concentration calibrated by the calibration coefficient to the calibration device. Here, the smoke concentration calibrated by the calibration coefficient refers to the actual smoke concentration obtained by multiplying the calibration coefficient with the current smoke concentration detected by the smoke sensing module, which can be recorded as the third smoke concentration.
[0048] After the calibration device obtains the calibration coefficient and the third smoke concentration of each smoke sensing module, it can directly determine whether the calibration of the smoke sensing module is successful by judging whether any or all of the two data, i.e., the calibration coefficient and the third smoke concentration, is reasonable. Alternatively, it can determine whether the calibration of the smoke sensing module is successful by combining the calibration coefficient and the third smoke concentration with the alarm condition of the smoke sensing module. Alternatively, it can determine whether the calibration of the smoke sensing module is successful by combining other data or using other methods. In short, it can determine whether the calibration of the smoke sensing module is successful.
[0049] As can be known from the above description, the above process of the present embodiment can realize full-automatic calibration of the smoke sensing module. Only manual installation of the smoke sensing module into the smoke box is required at the initialization stage, and subsequent calibration and other operations do not require manual operation. This can simplify the calibration process of the smoke sensing module, facilitate calibration operation by relevant technical personnel, improve production efficiency, and reduce labor costs. In addition, multiple smoke sensing modules can be calibrated simultaneously in an automated manner, thereby greatly shortening the calibration time, improving the calibration efficiency, and avoiding manual calibration errors.
[0050] In the embodiment, the calibration device controls the smoke generation module to generate smoke in the smoke box, controls the smoke measurement module to measure the smoke concentration in the smoke box and send the measured smoke concentration to the calibration device, and determines the smoke concentration at the time when the measured smoke concentration reaches the preset calibration range as the first smoke concentration, and then sends a calibration instruction including the first smoke concentration to the smoke sensing module to instruct the smoke sensing module to determine the calibration coefficient based on the second smoke concentration detected by the smoke sensing module and the first smoke concentration and calibrate itself. After the smoke sensing module is calibrated according to the calibration instruction, the calibration device can obtain the calibration coefficient sent by the smoke sensing module and the third smoke concentration after the calibration device is calibrated, and determine whether the smoke sensing module is successfully calibrated according to the calibration coefficient and the third smoke concentration. In the method, the calibration device can communicate with the smoke box to control the modules in the smoke box to generate smoke and measure the actual smoke concentration and send it to the calibration device. Thus, the calibration device can communicate with the smoke sensing module based on the measured actual smoke concentration to control the smoke sensing module to accurately calibrate based on the smoke concentration detected by the smoke sensing module and the actual smoke concentration, and then determine whether the smoke sensing module is successfully calibrated through the calibration coefficient returned by the smoke sensing module and the calibrated smoke concentration. In the calibration process, manual calibration is not required, and the whole process is an automatic calibration process. Therefore, the calibration time of the smoke sensing module can be shortened, the calibration efficiency is improved, the automatic calibration process can also avoid human calibration errors, and the accuracy of the calibration of the smoke sensing module is improved.
[0051] The following embodiment describes the specific implementation process of determining whether the smoke sensing module is successfully calibrated based on the calibration coefficient and the third smoke concentration.
[0052] Figure 3 is a flowchart of a second smoke sensing module calibration method provided by the application, as shown in Figure 3 The step 206 of determining whether the smoke sensing module is successfully calibrated based on the calibration coefficient and the third smoke concentration can include the following steps. Step 302: Determine whether the calibration coefficient is reasonable to obtain a first determination result.
[0053] The determination of whether the calibration coefficient is reasonable can be specifically determining whether the calibration coefficient is within a preset calibration coefficient range to obtain a first determination result. The preset calibration coefficient range can be a range in which a reasonable calibration coefficient is preset. Generally, the calibration coefficient of the smoke sensing module is within a reasonable coefficient range.
[0054] If the calibration coefficient of the smoke sensing module does not exceed the preset calibration coefficient range, i.e., the calibration coefficient is within the preset calibration coefficient range, it is determined that the calibration coefficient of the smoke sensing module is reasonable, i.e., the first judgment result of the smoke sensing module is that the calibration coefficient is reasonable. If the calibration coefficient of the smoke sensing module exceeds the preset calibration coefficient range, it is determined that the calibration coefficient of the smoke sensing module is unreasonable, i.e., the first judgment result of the smoke sensing module is that the calibration coefficient is unreasonable.
[0055] In step 304, a fourth smoke concentration measured by the smoke measuring module at the same time when the smoke sensing module obtains the third smoke concentration is obtained, and a second judgment result is determined according to the third smoke concentration and the fourth smoke concentration. The second judgment result is used to represent whether the third smoke concentration is reasonable.
[0056] In this step, at the same time when the smoke sensing module obtains the third smoke concentration, the smoke measuring module can also measure the smoke concentration in the smoke tank at the same time, which is recorded as the fourth smoke concentration. Then, according to the third smoke concentration calibrated by the smoke sensing module and the fourth smoke concentration measured by the smoke measuring module, it can be determined whether the third smoke concentration is reasonable, and a second judgment result is obtained.
[0057] As an optional embodiment, the way of determining the second judgment result according to the third smoke concentration and the fourth smoke concentration can include: calculating the absolute value of the difference between the third smoke concentration and the fourth smoke concentration; determining whether the absolute value of the difference is less than a preset threshold; if the absolute value of the difference is less than the preset threshold, it is determined that the second judgment result is that the third smoke concentration is reasonable, otherwise it is determined that the second judgment result is that the third smoke concentration is unreasonable.
[0058] The size of the preset threshold can be set according to actual conditions. Through the calculation of the absolute value of the difference between the third smoke concentration calibrated by the smoke sensing module and the fourth smoke concentration measured by the smoke measuring module, if the absolute value of the difference is less than the preset threshold, it means that the smoke concentration calibrated by the smoke sensing module is close to the smoke concentration measured by the smoke measuring module, so the third smoke concentration calibrated by the smoke sensing module is reasonable, i.e., the second judgment result is that the third smoke concentration is reasonable. If the absolute value of the difference is not less than (i.e., greater than or equal to) the preset threshold, it means that the smoke concentration calibrated by the smoke sensing module is far from the smoke concentration measured by the smoke measuring module, so the third smoke concentration calibrated by the smoke sensing module is unreasonable, i.e., the second judgment result is that the third smoke concentration is unreasonable.
[0059] In step 306, it is determined whether the smoke sensing module is successfully calibrated according to the first judgment result and the second judgment result.
[0060] After the first determination result of whether the calibration coefficient of the smoke sensing module is reasonable and the second determination result of whether the third smoke concentration calibrated by the smoke sensing module is reasonable, it can be determined whether the smoke sensing module is successfully calibrated.
[0061] As an optional embodiment, if the first determination result of the smoke sensing module is that the calibration coefficient is unreasonable, and / or the second determination result is that the third smoke concentration calibrated by the smoke sensing module is unreasonable, it is determined that the calibration of the smoke sensing module fails. In other words, if at least one of the calibration coefficient of the smoke sensing module and the third smoke concentration calibrated by the smoke sensing module is unreasonable, it can be determined that the calibration of the smoke sensing module fails. At the same time, in order to facilitate relevant personnel to know the calibration failure in time, the calibration device can output a message of calibration failure for relevant personnel to view when the calibration of the smoke sensing module fails.
[0062] As an optional embodiment, if the calibration coefficient of the smoke sensing module and the third smoke concentration calibrated by the smoke sensing module are both reasonable, the calibration success of the smoke sensing module can be further determined in combination with other parameters, and subsequent embodiments will be described in detail.
[0063] In this embodiment, the calibration success of the smoke sensing module is determined by combining the determination result of whether the calibration coefficient of the smoke sensing module is reasonable with the determination result of whether the smoke concentration calibrated by the smoke sensing module is reasonable, which can avoid the situation that at least one of the calibration coefficient of the smoke sensing module or the calibrated smoke concentration is unreasonable and mistakenly considered as calibration success, thereby improving the effect and accuracy of the calibration of the smoke sensing module. In addition, when at least one of the calibration coefficient of the smoke sensing module or the calibrated smoke concentration is unreasonable, it is determined that the calibration of the smoke sensing module fails, which can further improve the effect and accuracy of the calibration of the smoke sensing module. Further, whether the calibrated smoke concentration of the smoke sensing module is reasonable is determined by whether the calibrated smoke concentration of the smoke sensing module is close to the measured smoke concentration of the smoke measuring module, which is simple and intuitive, and thus the efficiency and accuracy of determining whether the calibrated smoke concentration of the smoke sensing module is reasonable can be improved, and the efficiency and accuracy of the calibration of the smoke sensing module can be effectively improved.
[0064] The following embodiments will describe the process of determining whether the calibration of the smoke sensing module is successful in combination with other parameters when the calibration coefficient of the smoke sensing module and the third smoke concentration calibrated by the smoke sensing module are both reasonable.
[0065] Figure 4 Fig. 3 is a flowchart of a third calibration method of a smoke sensing module according to the present application, Figure 5 Fig. 4 is a detailed flowchart of the calibration method of the smoke sensing module according to the present application, as shown in Figure 4 and Figure 5 As shown in Fig. 3, the calibration method of the smoke sensing module according to the present application comprises the following steps: If the first determination result is that the calibration coefficient is reasonable and the second determination result is that the third smoke concentration is reasonable, the smoke exhaust module is controlled to exhaust all the smoke in the smoke box in step 402.
[0066] In the case that the calibration coefficient of the smoke sensing module and the third smoke concentration calibrated by the smoke sensing module are both reasonable, the calibration device can send a smoke exhaust control instruction to the smoke exhaust module in the smoke box, and the smoke exhaust module can exhaust all the smoke generated in the smoke box after receiving the smoke exhaust control instruction. It can be understood that after all the smoke in the smoke box is exhausted, the smoke in the smoke sensing module is also exhausted correspondingly.
[0067] In this embodiment, all the smoke previously generated in the smoke box is exhausted, mainly to avoid the problem that the smoke in the smoke sensing module will affect the subsequent alarm test and thus affect the final calibration result, so as to improve the accuracy of the calibration result of the smoke sensing module determined subsequently.
[0068] After all the smoke in the smoke box is exhausted, the smoke generating module is controlled to generate smoke again, and whether the smoke sensing module generates an alarm message under the smoke generated again in the smoke box is determined to determine whether the smoke sensing module is calibrated successfully in step 404.
[0069] In this step, the calibration device can determine whether all the smoke in the smoke box and the smoke sensing module is exhausted by the real-time measured smoke concentration fed back by the smoke measuring module and / or the calibrated smoke concentration fed back by the smoke sensing module. After determining that all the smoke in the smoke box and the smoke sensing module is exhausted, the calibration device can resend a smoke generation control instruction to the smoke generating module, and the smoke generating module can generate smoke in the smoke box again after receiving the smoke generation control instruction, i.e., the smoke box is smoked again.
[0070] After the smoke in the smoke box is smoked again, whether the smoke sensing module is calibrated successfully can be determined according to whether the smoke sensing module generates an alarm message under the smoke generated again in the smoke box. As an optional embodiment, the process can include the following steps: In the case that the current smoke concentration in the smoke box reaches the target smoke concentration range, it is detected whether the smoke sensing module generates an alarm message; the target smoke concentration range is the smoke concentration range in which the smoke sensing module generates an alarm message, and the current smoke concentration is the smoke concentration measured by the smoke measuring module; If the smoke sensing module generates an alarm message and the smoke concentration included in the alarm message corresponds to the current smoke concentration, it is determined that the smoke sensing module is calibrated successfully; the smoke concentration included in the alarm message is the smoke concentration obtained by the smoke sensing module after calibrating the concentration of the smoke generated again in the smoke box based on the calibration coefficient.
[0071] The target smoke concentration range (may also be referred to as a reasonable smoke concentration range) corresponds to a smoke concentration range in which the smoke sensing module generates an alarm under an actual smoke concentration. The target smoke concentration range can include only one target smoke concentration value, or can include a smoke concentration range composed of an upper limit value and a lower limit value of the smoke concentration.
[0072] The smoke measuring module can send the current smoke concentration in the smoke tank measured by the smoke measuring module to the calibration device in real time, and the calibration device can continuously determine whether the current smoke concentration measured by the smoke measuring module reaches the target smoke concentration range. If the current smoke concentration reaches the target smoke concentration range, the smoke sensing module will generally generate an alarm message. At this time, the calibration device can detect whether the smoke sensing module generates an alarm message. If the smoke sensing module generates an alarm message, the alarm message generally includes the smoke concentration calibrated by the smoke sensing module based on the calibration coefficient, and also includes the address and type of the smoke sensing module. The calibration device can obtain the alarm message by interacting with the smoke sensing module, and then analyze the alarm message to obtain the smoke concentration calibrated by the smoke sensing module. Then, the calibration device can compare the smoke concentration calibrated by the smoke sensing module in the alarm message with the current smoke concentration measured by the smoke measuring module. If the two are close, it can be considered that the two correspond to or conform to each other. At this time, it can be considered that the calibration of the smoke sensing module is successful, and the alarm function of the smoke sensing module is normal. At the same time, a message indicating that the calibration is successful can be output for viewing.
[0073] If the smoke sensing module does not generate an alarm message, it can be a calibration failure or other situation. At this time, a message indicating that the alarm fails can be output to inform the relevant personnel that the alarm function of the smoke sensing module is abnormal.
[0074] In the embodiment, when the calibration coefficient or the calibrated smoke concentration of the smoke sensing module is reasonable, whether the alarm function of the smoke sensing module is normal can be used to determine whether the calibration of the smoke sensing module is successful. In this way, the calibration effect and calibration accuracy of the smoke sensing module can be effectively improved. In addition, when the smoke sensing module generates an alarm and the smoke concentration of the alarm corresponds to the actual smoke concentration, it is determined that the calibration of the smoke sensing module is successful. In this way, the calibration of the smoke sensing module can be more finely determined by combining the normal alarm of the smoke sensing module, and the calibration effect of the smoke sensing module can be further improved.
