DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] First of all, it should be explained that this embodiment is generated based on the purpose of the relevant government departments to protect the regional atmospheric environment and living environment. The existing technology often monitors whether the oil fume emissions of catering units meet the requirements by monitoring the oil fume concentration in the oil fume duct of the catering unit. Once the corresponding indicators are exceeded, the relevant catering units will be notified to make rectifications. However, due to the rapid accumulation of oil pollution in the oil fume duct, the sampling probes of the relevant detection equipment are easily covered by oil pollution and affect the detection results, resulting in this kind of monitoring method being ineffective and unable to achieve effective control effects. To this end, based on the above-mentioned ultimate goal, that is, protecting the regional atmospheric environment and living environment, this embodiment adopts a completely different technical concept, directly bypassing the existing technology for the detection of oil fume emission concentration in the oil fume duct, and can effectively supervise the oil fume emission behavior of catering units with simple and easy-to-promote means. The specific means are as follows.

[0019] like Figure 1 As shown, this embodiment provides a method for monitoring the linkage of a fume purification device in a catering unit, including the following steps: Step 100, monitoring whether the stoves of each catering unit have been activated, if so, proceeding to step 200; Step 200, detecting whether the oil fume purification device of the corresponding catering unit has been activated, if so, proceeding to step 300; if not, proceeding to step 400; Step 300, monitoring whether the exhaust fume concentration of the corresponding fume purification device is higher than a set threshold, if so, proceeding to step 400; Step 400, an alarm is sent to the corresponding catering unit.

[0020] According to relevant regulations, catering units with oil fume emission requirements need to install oil fume purification devices, and after being treated by oil fume purification devices, oil fume can generally meet the oil fume emission requirements, that is, it will not affect the atmospheric environment and living environment. However, whether the oil fume purification device is turned on or not often depends on the self-consciousness of the catering unit. The relevant government departments can generally only check whether the oil fume purification device of the catering unit is in normal use through regular on-site inspections, and cannot know whether the activation of the oil fume purification device covers the oil fume emission process.

[0021] Therefore, the core technical concept of this embodiment is: when the catering unit discharges oil fume, whether the oil fume purification device is turned on synchronously is monitored to ensure that the oil fume discharged into the atmosphere meets the requirements. In addition, when it is known that the catering unit is discharging oil fume, there must be a certain lag in detecting whether the oil fume purification device is turned on. During this period, some oil fumes that do not meet the requirements have been discharged into the atmosphere. Therefore, this embodiment uses the monitoring of whether the stove has been enabled to replace the detection of whether the oil fume has been discharged. Because the activation of the stove is bound to be earlier than the emission of oil fume, it is possible to detect whether the oil fume purification device is enabled before the oil fume is discharged, and it is also possible to remind the catering unit that has not turned on the oil fume purification device to turn it on in time before the oil fume is discharged, effectively avoiding the discharge of unpurified oil fume into the atmosphere.

[0022] In addition, due to the different types of oil fume purification devices installed in various catering units, their purification effects are also different, or the oil fume purification devices have been used for a long time, resulting in performance degradation or failure, so that even if they are turned on normally, they cannot meet the oil fume purification requirements. For this reason, this embodiment assists in detecting the concentration of oil fume discharged by the oil fume purification device to further ensure the supervision of oil fume emissions. It should be noted that, unlike the prior art that detects oil fume in the oil fume pipe, the concentration of oil fume after being treated by the oil fume purification device is significantly reduced, so it will not cover the sampling probe of the detection equipment in a short time, so as not to cause a large deviation in the detection results, so its detection results are more reliable and can be used as a basis for supervision.

[0023] Finally, when a catering unit engages in arbitrary illegal emissions, including failure to promptly turn on the fume purification device, and the fume purification device emitting fumes that do not meet the requirements, timely warnings should be issued and it should be ordered to correct the problem in order to effectively protect the regional atmospheric and living environment.

[0024] The following is a detailed description of each step.

[0025] In step 100, the monitoring of whether the stoves of each catering unit are enabled can be specifically carried out by installing a temperature sensor in the stove area to monitor the temperature value of the stove area, and judging whether the stove is enabled according to the change of the temperature value.

[0026] Since the types of stoves in various catering units are different, although some stoves are relatively intelligent and can directly obtain activation status information, most stoves are still traditional stoves and cannot directly obtain activation status information. The relevant government departments need to uniformly supervise the catering units in the entire region, so a universal, easy-to-implement, and effective method is needed to detect the activation status of the stoves in various catering units.

[0027] Therefore, this embodiment determines whether the stove is enabled by the temperature change of the stove. The temperature sensor has a low cost, a small structure, and is easy to install. It can be applied to the installation of different stoves. In general, considering the complexity of the kitchen environment and the large amount of water used on the stove, in order to avoid interference or damage to the temperature sensor, the temperature sensor can be installed in the space under the stove. The activation state of the stove can be determined based on the change in temperature value. Specifically, it can be determined that the stove is enabled based on the fact that the temperature in the stove area rises rapidly in a short period of time, for example, the temperature rises by more than 30°C within 5 minutes. Considering some special circumstances, such as frozen objects are placed on the stove for a long time, resulting in a decrease in the temperature of the stove area. After the frozen objects are removed, the temperature of the stove rises rapidly in a short period of time, which causes a misjudgment. For this reason, it can be added to the judgment condition: the stove area temperature exceeds a certain value of the room temperature, such as 30°C, before the stove is considered to be enabled. The room temperature data used does not need to be too accurate. For example, the temperature of the stove when it is idle can be obtained by the temperature sensor as the room temperature. Specifically, according to the temperature data monitored by the temperature sensor, the lower temperature that is stable for more than a certain period of time can be used as the room temperature. Of course, you can also add a temperature sensor and install it in an open space in the kitchen to obtain relatively accurate room temperature.

[0028] The above judgment process is generally completed in the supervision system of relevant government departments, and the temperature sensor is only used to obtain and upload temperature data. Of course, the corresponding judgment module can also be integrated into the temperature sensor to directly obtain the judgment result, and only upload the result to the supervision system of relevant government departments.

[0029] In step 200, the detection of whether the oil fume purification device of the catering unit is activated can be specifically carried out by installing a current sensor in the power supply circuit of the oil fume purification device to detect the current value in the power supply circuit of the oil fume purification device, and judging whether the oil fume purification device is activated according to the current value.

[0030] Since the types of oil fume purification devices installed in various catering units are different, although some oil fume purification devices are relatively intelligent and can directly obtain activation status information, most oil fume purification devices cannot directly obtain activation status information. The relevant government departments need to uniformly supervise the catering units in the entire region, so a versatile, easy-to-implement, and effective method is needed to detect the activation status of the oil fume purification devices of various catering units.

[0031] Therefore, this embodiment determines whether the oil fume purification device has been enabled by detecting the working current of the oil fume purification device. The current sensor has a low cost, a small structure, and is easy to install. It will not affect or damage the original structure of the oil fume purification device. It only needs to connect the current sensor in series to the independent power supply line of the oil fume purification device, and when the current value detected by the current sensor reaches the minimum working current of the oil fume purification device, the oil fume purification device is considered to be turned on. Of course, due to the different types of oil fume purification devices in various catering units, the corresponding working currents may also be different. For the convenience of implementing the scheme, the above-mentioned minimum working current can be set to a smaller value, because the current should be 0 in the unenabled state, so it is easy to distinguish the current in the enabled and unenabled states. The working current of the oil fume purification device on the market is generally between 0.5-2.5A, so the above-mentioned minimum working current can be set to 0.3A. In addition, since the minimum working current is small, in order to avoid some unexpected situations causing instantaneous current fluctuations in the power supply line, which causes misjudgment, a time can be set for current detection. For example, it is detected that the current in the power supply line reaches the minimum working current for 5 consecutive seconds before the oil fume purification device is considered to be enabled.

[0032] Similarly, the above judgment process is generally completed in the supervision system of the relevant government departments, and the current sensor is only used to obtain and upload current data. Of course, the corresponding judgment module can also be integrated into the current sensor to directly obtain the judgment result, and only upload the result to the supervision system of the relevant government departments.

[0033] In step 300, for monitoring the concentration of oil smoke emitted by the oil fume purification device, a conventional oil fume detector can be used to install the sampling probe of the oil fume detector in the oil fume pipe of the rear section of the oil fume purification device to sample the purified oil fume. The oil fume detector can directly analyze the oil fume concentration data, and generally the oil fume concentration data can be directly uploaded to the government supervision system, and the supervision system determines whether the oil fume concentration exceeds the standard according to the set threshold. Once the test result exceeds the standard, an alarm message is generally pushed to the relevant personnel of the catering unit by mobile phone text messages to inform them of the violation content and rectification measures. In addition, in order to facilitate more intuitive monitoring, the points of the corresponding illegal catering units can be marked in the digital map of the region, generally marked with red dots, so as to intuitively grasp the location and distribution of the illegal catering units, and facilitate the overall planning of supervision strategies. The red dots will be eliminated until the illegal catering units have lifted the illegal behavior.

[0034] In step 400, if it is detected that the stove of the catering unit has been activated and the oil fume purification device has not been activated, it is also necessary to warn the illegal catering unit. The alarm method is the same as step 300 and will not be repeated here.

[0035] Although the oil fume concentration after the oil fume purification device is low and will not cover the sampling probe of the oil fume detector in a short time, after long-term use, the sampling probe will still be covered, resulting in a large deviation in the detection results. Figure 2 As shown, as another implementation of the present supervision method, in addition to the above steps 100-400, the supervision method further includes: Step 500, according to the set cleaning cycle of the oil fume purification device of each catering unit, regularly push cleaning reminders to each catering unit, and receive cleaning photos uploaded by each catering unit; if the catering unit fails to upload cleaning photos within the specified time limit, an alarm is issued to the corresponding catering unit.

[0036] Specifically, unlike the cleaning of oil fume ducts, oil fume ducts are relatively long and generally hidden in the ceiling or wall, so it is inconvenient to clean. The oil fume purification device is generally set at the end of the oil fume duct, that is, on the outdoor wall, and its exhaust port is exposed to the outside, and it is easy to disassemble and assemble, so it is relatively convenient to clean. The cleaning cycle is generally a fixed number of days, which can be set according to the scale of the catering unit. The larger the scale, the shorter the cleaning cycle is generally. Cleaning photos generally include three photos before, during and after cleaning, and the cleanliness in the photos can be identified by image recognition technology, especially the photos after cleaning. The cleanliness in the photos after cleaning is used as the judgment standard, and the catering units that do not meet the cleaning requirements are warned accordingly. The warning method is as described above and will not be repeated here. In addition, considering that the catering unit may make a mistake in the order of uploading photos, that is, not strictly uploading in the order before, during and after cleaning, in order to reduce the task of the catering unit, the photos in the corresponding cleaning steps can be directly identified according to the cleanliness through image recognition technology.

[0037] In order to prevent catering units from repeatedly uploading previously taken photos, a historical photo database can be set up for each catering unit, and each time a new photo is received, it can be compared with the historical photos in the historical photo database through image recognition technology, so as to issue an alarm after recognizing that the catering unit has repeatedly uploaded photos. Alternatively, the catering unit can be required to take and upload photos in real time through the corresponding program, such as through the WeChat applet, which only supports taking and uploading photos, and cannot select photos in the mobile phone album, to ensure the authenticity of the cleaned photos.

[0038] Considering that the business of the same catering unit may also experience large fluctuations, the fixed cleaning cycle of the oil fume purification device may not be able to take into account the timeliness of the cleaning of the oil fume purification device and avoid increasing unnecessary labor intensity of the catering unit. To this end, step 500 can adopt another implementation method: accumulate the activation time of the oil fume purification device of the catering unit, and when the activation time reaches the set value, push a cleaning reminder to the catering unit. For different catering units, the setting value of the above-mentioned activation time can use the same value, and in order to take into account the scale of different catering units, corresponding coefficients can be allocated to different catering units, and when the product of the accumulated activation time of the oil fume purification device and the corresponding coefficient reaches the activation time setting value, a cleaning reminder is pushed to the corresponding catering unit.

[0041] The oil fume concentration detection module is used to detect the emission oil fume concentration of the corresponding oil fume purification device after receiving the information that the oil fume purification device has been activated from the purification device detection module; The alarm module is used to issue an alarm to the corresponding catering unit upon receiving feedback from the purification device detection module that the oil fume purification device is not enabled, or receiving feedback from the oil fume concentration detection module that the emission oil fume concentration is higher than the set threshold, or detecting that the catering unit has not uploaded cleaning photos within the specified period, and marking the location of the corresponding catering unit on the map.

[0042] like Figure 4 As shown, as another implementation of the present supervision system, in addition to the above modules, the supervision system also includes: The purification device cleaning supervision module is used to regularly push cleaning reminders to each catering unit according to the set cleaning cycle of the fume purification device of each catering unit, and receive cleaning photos uploaded by each catering unit; When the alarm module detects that the catering unit has not uploaded the cleaning photos within the specified period, it will alert the corresponding catering unit and mark the location of the corresponding catering unit on the map.

[0043] The specific working principle of this supervision system is the same as the above-mentioned supervision method and will not be elaborated here.
