Description

Technical Field

[0001] The present application relates to the field of sensors, and in particular to an oil smoke detection probe alarm system. Background Art

[0002] The existing restaurant oil fume monitoring and early warning method simply monitors whether the index value exceeds the national or local standards and issues an alarm. However, due to the cheating behavior of merchants privately moving the oil fume detection probes, the data measured by this method cannot reflect the actual oil fume emissions.

[0003] Therefore, a method is needed to identify whether the oil smoke detection probe has been illegally moved to determine whether the detected oil smoke data is accurate. Summary of the invention

[0004] The present application mainly provides an oil fume detection probe alarm system to solve the problem of oil fume monitoring data distortion.

[0005] In order to solve the above technical problems, a technical solution adopted in the present application is: to provide an oil fume detection probe alarm system, the oil fume detection probe alarm system comprising: an oil fume detection probe, used to detect the movement status of the oil fume detection probe, and to send a detection message based on the movement status of the oil fume detection probe; a server, used to receive the detection message sent by the oil fume detection probe, and to confirm whether the oil fume detection probe has been illegally moved based on the detection message, and to send an alarm message when it is confirmed that the oil fume detection probe has been illegally moved.

[0006] By detecting the illegal movement of the oil fume probe and generating an alarm message, the oil fume detection personnel can promptly understand whether the oil fume probe has been illegally moved, thereby eliminating false information in the monitoring data and restoring the oil fume detection probe in time to obtain accurate oil fume monitoring data.

[0007] In some embodiments, the movement status includes gravity acceleration data, and the oil smoke detection probe sends a detection message including an abnormal field when detecting that the gravity acceleration data changes by more than a preset threshold.

[0008] By detecting the movement state of the oil fume detection probe during the movement, a detection message is generated to determine whether the oil fume detection probe is illegally moved.

[0009] In some embodiments, the server is also used to parse the detection message and store the parsed detection message in a history table in the server, and confirm whether the oil fume detection probe has been illegally moved based on the history table in the server, wherein the history table contains detection messages obtained in the past.

[0010] By parsing the detection messages, monitoring equipment from different manufacturers can send data to the data management platform according to the same specifications, and parse out key information in the monitoring data, including equipment status, monitoring time, pollutant type and concentration, etc., thereby improving the accuracy and reliability of the data.

[0011] In some embodiments, the server further queries the number of consecutive abnormal fields of the detection message in the history table, and when the number of consecutive abnormal fields exceeds a threshold, confirms that the oil smoke detection probe has been illegally moved.

[0012] By detecting whether there are continuous detection messages within a period of time, misjudgment caused by accidental touch or slight shaking can be eliminated, so that the movement of the oil fume probe can be accurately detected.

[0013] In some embodiments, the server is further used to query the abnormal field density of the detection message in the history table, and when the abnormal field density in the history table exceeds a threshold density, confirm that the oil smoke detection probe has been illegally moved.

[0014] By detecting whether there are frequent detection messages within a period of time, the interference to the oil fume probe, such as slow movement or slight movement, can be identified to avoid the oil fume detection probe not being recognized due to short movement time and small amplitude.

[0015] In some embodiments, the server also issues an alarm message based on the power-off time of the oil smoke detection probe.

[0016] By detecting whether there is a power outage within a period of time, it is avoided that the detection message cannot be generated due to power disconnection.

[0017] In some embodiments, in response to the power off time of the oil fume detection probe exceeding a threshold time, the server obtains the power off time of the area where the oil fume detection probe is located, and issues an alarm message when the power off time of the oil fume detection probe does not belong to the power off time of the area.

[0018] By comparing the power-off time of the oil fume detection probe with the overall power-off time of the region, power outages caused by regional power outages can be eliminated and false alarm messages can be avoided.

[0019] In some embodiments, a motion sensor is provided in the oil smoke detection probe.

[0020] In some embodiments, the mobile sensor includes: a ball-containing plate, provided with a circular ball-containing groove; a small ball, placed in the ball-containing groove, and the diameter of the small ball is greater than the groove depth of the ball-containing groove; a floating cover assembly, including a floating cover and a flexible connector, the floating cover is provided on the ball-containing groove and presses the small ball, the flexible connector is connected to the ball-containing plate and elastically presses the floating cover; a three-axis acceleration sensor is installed on the floating cover; wherein, when the oil fume detection probe is in a stationary state, the small ball is in a random equilibrium state, and the three-axis acceleration sensor detects the movement state of the oil fume detection probe through the position change of the small ball in the ball-containing groove.

[0021] In some embodiments, the ball receiving groove is an inclined groove.

[0022] The beneficial effects of the present application are as follows: different from the prior art, the present application discloses an oil fume detection probe alarm system, which determines whether the oil fume detection probe is disturbed by detecting the moving state of the oil fume detection probe, and sends a detection message with an abnormal field when the moving state changes, so that the server can obtain the movement of the oil fume detection probe; the server confirms whether the oil fume detection probe has been illegally moved based on the detection message, which can effectively eliminate the alarm information caused by accidental touch or slight vibration from being misjudged as illegal movement; and sends an alarm message when it is confirmed that the oil fume detection probe has been illegally moved, so that the oil fume detection personnel can promptly understand whether the oil fume probe has been illegally moved, thereby eliminating false information in the monitoring data and promptly restoring the oil fume detection probe to obtain accurate oil fume monitoring data.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of an embodiment of an oil smoke detection probe alarm system provided by the present application. The oil smoke detection probe alarm system 100 includes:

[0030] The oil fume detection probe 110 is used to detect the movement state of the oil fume detection probe 110 and send a detection message based on the movement state of the oil fume detection probe 110. The oil fume detection probe 110 can detect and monitor the oil fume concentration and particulate matter concentration of the flue where the oil fume detection probe 110 is currently located in real time. Optionally, the types of the oil fume detection probe 110 include electrochemical sensing type, optical sensing type, light scattering sensing type, infrared sensing type, laser sensing type, etc.

[0031] In order to prevent merchants from interfering with the detection of the oil fume detection probe 110 by moving the probe or blocking the probe, a movement detection function is provided on the oil fume detection probe 110. When the oil fume detection probe 110 is moved, the oil fume detection probe 110 responds to the change of its own movement state and sends a detection message containing an abnormal field to the server 120.

[0032] Further, see Figure 2 The oil smoke detection probe 110 is provided with a mobile sensor 200, and the mobile sensor 200 includes:

[0033] The ball-receiving plate 210 is provided with a circular ball-receiving groove 211. The ball-receiving plate 210 can be installed inside the oil fume detection probe 110 as a separate part, or it can be integrated with a part inside the oil fume detection probe 110. When the oil fume detection probe 110 is installed and fixed, the ball-receiving plate 210 needs to be in a roughly horizontal position so that the small ball in the ball-receiving groove 211 can roll under the influence of gravity when the oil fume detection probe 110 changes its posture. If the installation angle of the ball-receiving plate 210 deviates too far from the horizontal, when the oil fume detection probe 110 changes its posture, the small ball 220 is likely to be in a balanced state without moving, resulting in the movement state of the oil fume detection probe 110 not being detected.

[0034] Optionally, the ball receiving groove 210 is an inclined groove, and the groove depth at each location in the groove is inclined from the shallowest to the deepest, so that when the ball 220 rolls in the ball receiving groove 210, the tilt angle of the upper floating cover 231 changes more obviously, thereby improving the movement detection accuracy of the oil fume detection probe 110.

[0035] The small ball 220 is placed in the ball receiving groove 221 , and the diameter of the small ball 220 is greater than the depth of the ball receiving groove 221 .

[0036] The floating cover assembly 230 includes a floating cover 231 and a flexible connector 232. The floating cover 231 is disposed on the ball receiving groove 211 and presses the ball 220. The flexible connector 232 is connected to the ball receiving plate 210 and elastically presses the floating cover 231. When the ball 220 rolls in the ball receiving groove 211, the floating cover 231 has different tilting postures relative to the ball receiving plate 210. The flexible connector 232 can limit the lifting height of the floating cover 231, ensuring that the maximum distance between the floating cover 231 and the edge of the ball receiving groove 221 is less than the diameter of the ball 220, ensuring that the ball 220 will not fall out of the ball receiving groove in any posture.

[0037] When the oil fume detection probe 110 changes its posture, the ball 220 rolls in the ball receiving groove 221 and changes the tilt angle of the floating cover 231 , so that the movement state of the oil fume detection probe 110 can be quantitatively detected through the tilt angle of the floating cover 231 .

[0038] The triaxial acceleration sensor 240 is installed on the floating cover 231. The triaxial acceleration sensor 240 provides judgment data for judging the movement state change of the oil smoke detection probe 110 by detecting the tilt angle of the floating cover 231.

[0039] The three-axis acceleration sensor 240 and the related detection circuit can measure the acceleration vector of the floating cover 231 in the current posture, and express it with the coordinate components in the three coordinate directions of its connected rectangular coordinate system. Since the oil smoke detection probe 110 is fixed on the flue and remains stationary during operation, the three-axis acceleration sensor 240 can determine the tilt posture of the floating cover relative to the horizontal plane based on the three coordinate components of the measured gravity acceleration.

[0040] During the movement of the oil fume detection probe 110, the change in the posture of the oil fume detection probe 110 and the vibration of a certain amplitude will cause the small ball 220 to roll in the ball receiving groove 211, thereby changing the tilt posture of the floating cover 231. The three-axis acceleration sensor 240 and the related detection circuit identify the movement of the oil fume detection probe 110 by detecting the change in the acceleration and the change in the tilt posture of the floating cover 231.

[0041] Specifically, the movement status includes gravity acceleration data. When the oil smoke detection probe 110 detects that the change of gravity acceleration data exceeds a preset threshold, it sends a detection message including an abnormal field.

[0042] The oil fume detection probe 110 obtains the three coordinate components of the gravity acceleration detected by the three-axis acceleration sensor 240 on the floating cover 231. If the change in the coordinate components of the gravity acceleration data exceeds a preset threshold, it means that the ball 220 has moved significantly, that is, the oil fume detection probe 110 has moved. In response to the movement of the oil fume detection probe 110, the oil fume detection probe 110 sends a detection message containing an abnormal field to the server 120. The server 120 determines whether the movement behavior is an illegal movement based on the information of the abnormal field in the received detection message.

[0043] The server 120 is used to receive the detection message sent by the oil fume detection probe 110, and confirm whether the oil fume detection probe has been illegally moved based on the detection message, and issue an alarm message when it is confirmed that the oil fume detection probe has been illegally moved.

[0044] The server 120 receives the detection message of the oil smoke detection probe 110 through the network interface or the dedicated communication route, and judges the movement state of the current oil smoke detection probe 110 in combination with the historical detection message information, and analyzes whether the oil smoke detection probe 110 has been illegally moved. If the detection result is that the smoke detection probe 110 has been illegally moved, a corresponding alarm message is sent to the management personnel or the system, so that the oil smoke detection personnel can timely understand whether the oil smoke probe has been illegally moved, thereby eliminating the false information in the monitoring data, and timely restore the oil smoke detection probe to obtain accurate oil smoke monitoring data.

[0045] Specifically, the alarm information includes the number, location, abnormal movement, and movement occurrence time of the oil smoke detection probe 110.

[0046] Furthermore, the server 120 is also used to parse the detection message and store the parsed detection message in a history table in the server 120, and confirm whether the oil smoke detection probe has been illegally moved based on the history table in the server 120, wherein the history table contains the detection messages obtained in the past time.

[0047] According to the HJ 212-2017 protocol of the Environmental Protection Bureau, the message sent by the oil smoke detection probe 110 is received and parsed, and the real-time message data is analyzed.

[0048] HJ 212-2017 "Data Transmission Standard for Online Pollutant Monitoring (Monitoring) Systems" is an important standard for guiding the construction of online pollutant monitoring systems and regulating data transmission. It specifies the data format and code definition of the data transmission process, including data commands, control commands, parameter commands, etc., as well as the corresponding field comparison table and coding rules.

[0049] Receiving and parsing monitoring messages according to the HJ 212-2017 protocol has the advantages of unified data format, high transmission efficiency, high accuracy, strong compatibility, good scalability and high management efficiency, which is conducive to improving the efficiency and quality of oil fume monitoring work.

[0050] According to the HJ 212-2017 protocol and business requirements, the parsed detection message is stored in the history table. The history table stores the detection message data within the past preset time period.

[0051] The history table is a database table used to store the relationship information between two or more tables. Specifically, the history table includes detection message data segment, fume probe identification, alarm type, detection time, insertion time, alarm status, probe location information or original message and other related data.

[0052] Specifically, the preset time period can be 1 minute, 3 minutes, 5 minutes, 8 minutes, 10 minutes, 11 minutes, 14 minutes, 18 minutes, 20 minutes or 25 minutes, etc.

[0053] The acquired message is combined with the historical message information to judge whether the oil smoke detection probe 110 has been illegally moved as a whole, so as to avoid false alarms caused by data transmission errors or false touches.

[0054] Optionally, the server 120 further queries the history table for the number of consecutive abnormal fields of the detection message, and when the number of consecutive abnormal fields exceeds a threshold, it is confirmed that the oil smoke detection probe 110 has been illegally moved.

[0055] The number and current position information of the oil fume detection probe 110 related to the abnormal field are extracted from the detection message clock, and the position detection is performed with other detection messages with the same probe number and position information in the history table, and the position of the detection message field with the same probe number and position information in the data storage unit is judged, and the time interval between each message field and the number of fields with consecutive detection messages are determined.

[0056] If a specific value of an abnormal field in a detection message with the same probe number and location information appears continuously, and the number of fields that appear continuously exceeds a preset threshold, it is determined that the oil smoke detection probe has been illegally moved.

[0057] For example, there is a field Position-Code in the system, which is used to record the current position code of the oil smoke detection probe. If the values ​​of the field Position-Code are different in multiple consecutive data records, or in 5 or more consecutive data records, and these changes are not recorded in the maintenance log, then this may indicate that the probe has been illegally moved.

[0058] For another example, the values ​​of fields such as SB2-MotionDetected indicating detected motion, or SB3-UnauthorizedAccess indicating unauthorized access indicate that an abnormality exists, and these abnormalities occur multiple times in succession, such as if the value of the field is 1 for 10 consecutive fields, then this may indicate that the probe has been illegally moved.

[0059] By detecting whether there are abnormal fields that occur continuously over a period of time, misjudgment caused by accidental touches or slight shaking can be eliminated, so that the movement of the oil smoke detection probe 110 can be accurately detected.

[0060] Optionally, the server 120 is further configured to query the abnormal field density in the history table, and when the abnormal field density of the detection message in the history table exceeds a threshold density, confirm that the oil smoke detection probe 110 has been illegally moved.

[0061] The number and current position information of the oil fume detection probe are extracted from the detection message clock, and the position detection is performed on the abnormal fields with the same probe number and position information pre-stored in the data storage unit. The number of abnormal fields with the same probe number and position information in the data storage unit within a certain window time is determined, and the density of the abnormal fields is calculated.

[0062] If a specific value of the abnormal field in the detection message with the same probe number and location information appears frequently within a certain time window, and the density of the consecutively appearing fields exceeds the preset threshold density, it is determined that the oil smoke detection probe 110 has illegally moved.

[0063] For example, there is a field Position-Code in the system, which is used to record the current position code of the oil smoke detection probe. If there are 15 or more data records with abnormal values ​​in the field Position-Code among multiple data records within 30 minutes, and these changes are not recorded in the maintenance log, then this may indicate that the probe has been illegally moved. Or record the time when the field Position-Code appears 15 times, if there are 15 data records with abnormal values ​​in the field Position-Code for less than 30 minutes, then the field density exceeds the preset threshold density, and the oil smoke detection probe 110 has been illegally moved.

[0064] For another example, the values ​​of fields such as SB2-MotionDetected indicating detected motion, or SB3-UnauthorizedAccess indicating unauthorized access indicate that an abnormality exists, and these abnormalities occur multiple times within a certain period of time. For example, if 8 out of 10 fields that appear within 10 minutes have a value of 1, then this may indicate that the probe has been illegally moved.

[0065] By detecting whether there are frequent abnormal fields in the detection message within a period of time, the interference to the oil fume probe, such as slow movement or slight movement, can be identified to avoid the oil fume detection probe 110 not being recognized due to short movement time and small amplitude.

[0066] Furthermore, the server 120 also issues an alarm message based on the power-off time of the oil smoke detection probe 110 .

[0067] Specifically, in response to the power off time of the oil smoke detection probe 110 exceeding the threshold time, the server 120 obtains the power off time of the area where the oil smoke detection probe 110 is located, and issues an alarm message when the power off time of the oil smoke detection probe 110 does not belong to the power off time of the area.

[0068] The power status of the oil fume detection probe 110 is detected through the power detection mechanism, and the time when the power outage starts and the time when the power is restored are recorded. The preset time threshold is compared with the power outage time of the oil fume detection probe 110. If the power outage time of the oil fume detection probe 110 exceeds the preset time threshold, based on the probe location information contained in the detection message, the system queries the power supply situation of the area where the oil fume detection probe 110 is located to determine whether the power outage is caused by a regional power outage.

[0069] If the power outage time of the oil fume detection probe 110 exceeds the preset time threshold and no regional power outage or maintenance occurs during this period, the power outage can be regarded as a power outage caused by illegal cutting off of the power supply of the oil fume detection probe 110. The probe may be illegally moved or illegally modified, such as blocked, etc. The server issues an alarm message corresponding to the power outage of the oil fume detection probe 110.

[0070] For example, the power outage threshold is set to 2 hours, and a restaurant's oil smoke detection probe suddenly loses power. The system detects this event and records the start time of the power outage as 10:00 a.m. The probe still has not been restored to power until 12:01 p.m. The system detects that the power outage time of the oil smoke detection probe has exceeded the set 2-hour threshold. At this time, the system tries to obtain the power outage information in the area, and finds that there is no regional power outage in the current area, and the mall where the restaurant is located has normal power supply. The system generates an alarm message, including: "The oil smoke detection probe (No. 231) lost power at 10:00 a.m. and has not been restored for more than 2 hours. Please check the power supply and lines to confirm whether there is an illegal power outage or equipment failure."

[0071] By comparing the power-off time of the oil fume detection probe with the overall power-off time of the region, power outages caused by regional power outages can be eliminated and false alarm messages can be avoided.

[0072] Different from the prior art, the present application provides an oil fume detection probe alarm system 100, which determines whether the probe has moved through the built-in motion sensor of the oil fume detection probe 110, and sends a detection message to the server 120 for data analysis in case of movement of the probe. The server 120 obtains the detection message, parses and stores it, combines the message information with the historical message data, analyzes the continuity and density of the abnormal message field, determines whether the movement constitutes an illegal movement of the probe, and generates an alarm message for the illegal movement behavior. At the same time, in the case where the oil fume detection probe 110 is powered off and a message cannot be generated, it is detected whether the power off of the oil fume detection probe 110 is artificially generated, and an alarm message is generated for the illegal power off behavior.
