Detailed Description
Example 1:
in this embodiment, a network-based oil smoke monitoring method is provided, which aims to enable a remote monitoring center to determine whether an oil smoke purifier located on site (catering enterprises) is actually put into use according to preset conditions.
Referring to fig. 1, a network-based oil smoke monitoring method is characterized by comprising the following steps:
step S1, waiting for receiving the first remote information and the second remote information;
step S2, acquiring a first detection threshold;
step S3, obtaining a first difference between the first remote information and the second remote information;
step S4, determining whether the first difference satisfies a first detection threshold;
step S401, if the first difference value meets a first detection threshold value, outputting first working information;
and S402, otherwise, outputting first alarm information.
The first remote information specifically includes: the entrance (air intake department) of the fan that is located the scene, or the signal of telecommunication that first oil smoke monitor probe 2 inside the fan sent, and this signal of telecommunication transmissible to first communication device department, and first communication device can be with the signal of telecommunication conversion that first oil smoke monitor probe 2 sent first remote information to can send first remote information to the remote monitoring center.
And the second remote information is specifically: the second oil smoke monitoring probe positioned at the evacuation position (namely the position communicated with the atmosphere) of the oil smoke channel on site sends out an electric signal which can be transmitted to the second communication device, and the second communication device can convert the electric signal sent out by the second oil smoke monitoring probe into second remote information and can send the second remote information to the remote monitoring center.
After the remote monitoring center receives the first remote information and the second remote information, the remote monitoring center obtains a first difference value of the first remote information and the second remote information according to a preset condition; the first difference value may be one of the following differences in information: temperature information, humidity information, oil smoke concentration information, particulate matter concentration information, and the like.
The first difference is exemplified as the difference of the temperature information.
Suppose a: if a certain catering enterprise is positioned at an outlet of the fan as a starting point and is provided with a second oil smoke exhaust pipeline which is parallel to the oil smoke channel and can bypass the oil smoke purification device, after the fan is started, oil smoke can flow through the first oil smoke monitoring probe 2 to the direction of the fan along the first oil smoke monitoring probe 2, then the oil smoke flows into the fan, and at the moment, the first oil smoke monitoring probe 2 obtains a first temperature electric signal; the oil smoke discharges out of the fan under the supercharging effect of the fan, bypasses the oil smoke purifier along the second oil smoke discharge pipeline and is discharged into the atmosphere, at the moment, the oil smoke does not actually flow through the second oil smoke monitoring probe, and the second temperature electric signal obtained by the second oil smoke monitoring probe is actually the atmospheric temperature. Under the condition, the first communication device sends the first temperature electric signal to the remote monitoring center as first remote information, and the second communication device sends the second temperature electric signal to the remote monitoring center as second remote information, the remote monitoring center obtains a first difference value (namely a temperature difference value) of the first remote information and the second remote information, at the moment, the remote monitoring center compares the first difference value with a first detection threshold value, if the first difference value cannot meet the first detection threshold value, the situation (catering enterprises) actually generates and makes oil smoke discharge actions, but the oil smoke discharge does not actually flow through the oil smoke purifier and the second oil smoke monitoring probe, and at the moment, the remote monitoring center should send an alarm.
The first difference is taken as the difference of the soot concentration information for example.
Suppose B: if a certain catering enterprise is positioned at an outlet of a fan as a starting point and is provided with a second oil smoke exhaust pipeline which is parallel to an oil smoke channel and can bypass an oil smoke purification device, but the second oil smoke exhaust pipeline is communicated with the original oil smoke channel after bypassing the oil smoke purification device, after the fan is started, oil smoke can flow through a first oil smoke monitoring probe 2 to the direction of the fan along the first oil smoke monitoring probe 2, then the oil smoke flows into the fan, and at the moment, the first oil smoke monitoring probe 2 obtains a first oil smoke concentration electric signal; the oil smoke is discharged out of the fan under the pressurization effect of the fan, bypasses the oil smoke purifier along a second oil smoke discharge pipeline, flows through a second oil smoke monitoring probe in an oil smoke channel communicated with the atmosphere and is discharged into the atmosphere, and at the moment, the second oil smoke monitoring probe obtains a second oil smoke concentration electric signal. Under the condition, the first communication device sends the first oil smoke concentration electric signal serving as first remote information to the remote monitoring center, and the second communication device sends the second oil smoke concentration electric signal serving as second remote information to the remote monitoring center, the remote monitoring center obtains a first difference value (namely an oil smoke concentration difference value) between the first remote information and the second remote information, at the moment, the remote monitoring center compares the first difference value with a first detection threshold value, if the first difference value cannot meet the first detection threshold value, the situation (catering enterprises) actually generates and makes an oil smoke emission action, but the oil smoke emission does not actually flow through the oil smoke purifier, and at the moment, the remote monitoring center should send an alarm.
It can be known from the description of the assumption a and the assumption B that, in the oil smoke monitoring method based on the network provided by this embodiment, by obtaining the first difference value between the first remote information and the second remote information and comparing the first difference value with the first detection threshold value, it can be determined whether the oil smoke discharged on site actually flows through the oil smoke purifier, so that at least some online monitoring devices of the oil smoke purifier in the prior art are solved, and there is a technical problem that a remote monitoring center cannot distinguish whether the oil smoke purifier on site is actually used.
Further, in this embodiment, referring to fig. 2, the obtaining the first difference value between the first remote information and the second remote information in step' comprises:
step S310, judging whether the first remote information and the second remote information are respectively valid, and acquiring a first judgment result;
step S311, if one of the first remote information and the second remote information is judged to be invalid data, the first judgment result is false, and second alarm information is output;
in step S312, otherwise, the first determination result is true.
Specifically, for example, if the oil smoke concentration in the first remote information or the second remote information is actually greater than the atmospheric pollutant concentration at the remote monitoring center, or actually greater than the historical oil smoke concentration stored in the remote monitoring center, the remote monitoring center may make the oil smoke concentration in the first remote information and/or the second remote information as invalid data according to a preset condition.
After obtaining the result of invalid data, the remote monitoring center should output second alarm information. The second alarm information can prompt a worker to go to a site to detect whether the catering enterprise actually discharges oil smoke or not, and whether the first oil smoke monitoring probe 2 or the second oil smoke monitoring probe is damaged or not.
Further, in this embodiment, referring to fig. 3, the step of obtaining the first difference value between the first remote information and the second remote information' further includes:
step S320, obtaining a first time node of the first remote information and a second time node of the second remote information;
step S321, judging whether the first time node and the second time node respectively meet the first time threshold value, and obtaining a second judgment result;
step S322, if the first time threshold is met, the second determination result is true;
and step S323, if not, the second judgment result is false, and third alarm information is output.
In an environment where oil smoke is actually emitted on site, a network communication fault may occur, and the first remote information and the second remote information cannot be sent out. For example: and the first communication device or the second communication device positioned on the site fails. In this case, the first remote communication device or the second remote communication device should store the first remote information or the second remote information, and send the first remote information to the remote monitoring center after the network failure is eliminated; at this time, the first remote information and the second remote information received by the remote monitoring center may not be the first remote information and the second remote information generated by the node at the same time. In this case, the remote monitoring center can process at least the following two methods: the method comprises the steps that if a current time node is a first time threshold (working time of a catering enterprise), first remote information and second remote information of the same time node are processed to obtain a first difference value, and the method II stores the first remote information and processes the first remote information and the second remote information of the non-same time node at a non-first time threshold (non-business time of the catering enterprise), so that the calculation pressure of a remote monitoring center within the first time threshold is reduced.
Within a first time threshold, if the remote monitoring center receives the first remote information and the second remote information in a non-fault state and the first remote information and the second remote information after the fault is eliminated at the same time; or within a first time threshold, only the first and second remotes after the failure is resolved can be received; then, the remote monitoring center should send third alarm information for prompting the worker when receiving the first remote information and the second remote information after the failure is eliminated.
Further, referring to fig. 4, the step of obtaining the first difference value between the first remote information and the second remote information' further includes:
step S330, judging whether the time difference between the first time node and the second time node meets a second time threshold value, and obtaining a third judgment result;
step S331, if the second time threshold is met, the third judgment result is true;
and S332, if not, outputting fourth alarm information if the third judgment result is false.
In the foregoing, there is a possibility that a relatively large number of first remote information and second remote information after the failure is eliminated are processed within a non-first time threshold, so that the calculation pressure of the remote monitoring center increases within the non-first time threshold. It should be understood that catering establishments are of many types, for example: the catering enterprises which are only in breakfast business, noon business and evening business, the catering enterprises which are in daytime business and/or night business, the catering enterprises which are in 24-hour uninterrupted business all day, and the like. Therefore, from the perspective of the remote monitoring center, it may face a normal operation state that satisfies a 'first time threshold' of one part of the catering enterprises for 24 hours all day, and an abnormal operation state that does not satisfy a 'non-first time threshold' of another part of the catering enterprises at the same time.
Therefore, by adopting the method of determining whether the time difference between the first time node and the second time node satisfies the second time threshold, the received first remote information and second remote information of the nodes at different time can be abandoned before the remote monitoring center actually processes the first remote information and second remote information of the nodes at different time, which are not the first time threshold (non-business time of catering enterprises), and outputs fourth alarm information for prompting staff and generating history records, thereby reducing the possibility that the remote monitoring center is in a normal working state meeting the 'first time threshold' of a part of catering enterprises in 24 hours all day, and at the same time in the case of an abnormal working state ' not meeting the ' non-first time threshold ' of another part of catering enterprises.
Further, in this embodiment, referring to fig. 5, before the step 'waiting for receiving the first remote information and the second remote information', the method further includes:
and 7, receiving the first remote information and the second remote information after outputting the first control information.
The catering enterprise is in non-operating time, and the fan system that is located locally should cut off the power supply to make fan, first oil smoke monitor probe 2, second oil smoke monitor probe and the oil smoke clarifier that the fan system contained be in non-operating condition, reduce catering enterprise's economic cost. However, if only local fan systems are relied on and the traditional electric cabinet is used to control the fan systems, some catering enterprises reduce the economic cost of using the fan systems during working hours, such as: start local fan system in first section operating time, and close fan system in second section operating time, change into parallel second oil extraction cigarette pipeline to atmosphere emission to caused the remote monitoring center to distinguish, in the operating time, whether the food and beverage enterprise actually discharges to the atmosphere through second oil extraction cigarette pipeline. The root cause of this problem is that the remote monitoring center has no control over the start and stop of the local fan system.
Therefore, by adopting the control method of the embodiment, the local fan system sends the third remote information to the remote monitoring center; and after receiving the third remote information, the remote monitoring center sends first control information to the local fan system. After receiving the first control information, the local fan system starts the fan system (including the starting fan, the first oil smoke monitoring probe 2, the second oil smoke monitoring probe and the oil smoke purifier), and at this time, the local fan system outputs first remote information and second remote information to the remote monitoring center. The remote monitoring center receives the first remote information and the second remote information after outputting the first control information. By adopting the control method of the embodiment, the remote monitoring center can realize the effect of controlling the starting of the local fan system.
Further, in this embodiment, referring to fig. 6, after the step 'receiving the first remote information and the second remote information after outputting the first control information', the method further includes:
step 8, waiting for receiving fourth remote information;
and 9, outputting second control information according to preset time after receiving the fourth remote information.
In all the foregoing, the remote monitoring center only judges through the first remote information and the second remote information, or respectively judges through the first remote information and the second remote information and the first time threshold or the second time threshold, so as to draw a conclusion that some catering enterprises actually use the oil smoke purifier. However, the working time of some catering enterprises is not continuously fixed, and an extreme application scenario is as follows: in the preset working time of some catering enterprises, two modes of oil smoke emission are adopted, wherein in the first working time period, a fan and an oil smoke monitoring system are used, and in the second working time period, the fan and the oil smoke monitoring system are shut down. That is, the fan system or whether the fan is used in the preset working time is not monitored by the remote monitoring system.
Therefore, by adopting the control method of the embodiment, the local fan system sends the fourth remote information to the remote monitoring center; and after receiving the fourth remote information, the remote monitoring center sends second control information to the local fan system in a delayed manner according to preset time. For example: if the preset time is three minutes, after the remote monitoring center receives the fourth remote information, the remote monitoring center can generate second control information, and the second control information is delayed for three minutes and then is sent to the local fan system. After the local fan system receives the second control information, the fan system is shut down (including the starting fan, the first oil smoke monitoring probe 2, the second oil smoke monitoring probe and the oil smoke purifier), and at the moment, the local fan system outputs the first remote information and the second remote information to the remote monitoring center to be respectively interrupted. By adopting the control method of the embodiment, the remote monitoring center can realize the effect of controlling the local fan system to be shut down.
After the remote monitoring center receives the fourth remote information and before the fourth remote information is delayed according to the preset time and second control information is sent to the local fan system, the remote monitoring center determines whether the second control information is sent or not according to the change results of the first remote information and the second remote information in the preset time; during the preset time, if the first remote information and the second remote information at the later time node respectively have a descending trend relative to the first remote information and the second remote information at the previous time node, the remote monitoring center at the moment should output the second control information, and conversely, during the preset time, if one of the first remote information and the second remote information at the later time node does not have a descending trend relative to the first remote information or the second remote information at the previous time node, the remote monitoring center at the moment should prevent the second control information from being sent to the local fan system even if the preset time is met, so that the fan located on the site continues to work.
Example 2:
in this embodiment, corresponding to the foregoing embodiment 1, a fan control method is provided to implement control of a local fan system.
Referring to fig. 7, a fan control method includes:
step S10, outputting the third remote information;
step S11, waiting for receiving the first control information;
step S12, after receiving the first control information, transmits the first remote information and the second remote information.
The local fan system outputs third remote information to the remote monitoring center; for example: when a catering enterprise is close to the working time or in the working time, a certain worker presses a 'starting button' to enable a local fan system to be powered on, and at the moment, the local fan system automatically sends third remote information to the remote monitoring center. The local fan system sends the third remote information to the remote monitoring center, which can be implemented by using the prior art, including but not limited to: and sending third remote information to the remote monitoring center by adopting a third communication device communicated with the local fan system. The third communication device can be a 4G/5G device and also can be a WIFI device.
After the local fan system receives the first control information, the local fan system is started, wherein the fan is powered on to start rotating, the first oil smoke monitoring probe 2 and the second oil smoke monitoring probe are respectively powered on to output electric signals, and then the first remote information and the second remote information which are sent to the remote monitoring system are respectively formed through the first communication device and the second communication device.
Further, referring to fig. 8, the fan control method includes:
step S13, outputting fourth remote information;
step S14, waiting for receiving second control information according to a second time threshold;
in step S15, after receiving the second control information, the transmission of the first remote information and the second remote information is terminated.
The local fan system outputs fourth remote information to the remote monitoring center; for example: when the catering enterprise is close to the end of the working time or is out of the working time, a certain worker presses a 'stop button', and at the moment, the local fan system automatically sends fourth remote information to the remote monitoring center. The fourth remote message may be sent via the third communication device.
After the local fan system receives the second control information, the local fan system is shut down, wherein the fan stops rotating when the fan is powered off, the first oil smoke monitoring probe 2 and the second oil smoke monitoring probe stop outputting electric signals when the first oil smoke monitoring probe and the second oil smoke monitoring probe are powered off respectively, and the first remote information and the second remote information are interrupted from outputting.
If the local fan system does not receive the second control information within a certain time (i.e., within the preset time for delaying the output of the second control information mentioned in embodiment 1), the local fan system may send the fourth remote information to the remote monitoring center again, but if a certain staff member presses the 'stop button' again.
