[0049] Embodiment 1

[0050] Figure 1 A flowchart of a method for controlling a fume monitoring device is provided for the first embodiment of the present invention. This embodiment is applicable to the case where an electromagnetic pump in a fume monitoring device is dynamically adjusted. The method for controlling a fume monitoring device can be executed by a fume monitoring device control device. The fume monitoring device control device can be implemented in the form of hardware and / or software. The fume monitoring device control device can be configured in the fume monitoring device. Figure 1 As shown, the control method of the oil fume monitoring equipment includes:

[0051] S110, obtaining the current air pressure of the gas pipeline when the oil fume monitoring device is in the current installation position, and determining the first theoretical operating flow rate of the electromagnetic pump in the oil fume monitoring device according to the current air pressure of the gas pipeline.

[0052] Among them, considering that the adjustment of the fan during the use of the oil fume monitoring equipment will cause the wind pressure in the smoke exhaust duct to change, combined with the installation position of the oil fume monitoring equipment in the smoke exhaust and monitoring system, this embodiment obtains the current air duct wind pressure of the oil fume monitoring equipment at the current installation position based on the actual control scenario, so as to ensure the accuracy of the control of the current oil fume monitoring equipment.

[0053] The current air pressure in the gas pipeline can be collected by a wind pressure detection module arranged in the oil fume monitoring device. The current air pressure in the gas pipeline detected in real time by the wind pressure detection module is the wind pressure size in the current use environment when the oil fume monitoring device is in the current installation position.

[0054] After obtaining the current air pipeline wind pressure in the current usage environment, determine whether the current air pipeline wind pressure is greater than the set positive pressure limit, or determine whether the current air pipeline wind pressure is greater than the set negative pressure limit, and then determine whether the current air pipeline wind pressure exceeds the normal applicable range under the current usage environment.

[0055] The set positive pressure limit is the maximum positive pressure value applicable to the use environment of the oil fume monitoring equipment, and the set negative pressure limit is the maximum negative pressure value applicable to the use environment of the oil fume monitoring equipment. This embodiment does not impose any restrictions on the specific values ​​of the equipment positive pressure limit and the set negative pressure limit.

[0056] Specifically, if the current air pipeline wind pressure is greater than the set positive pressure limit, or the current air pipeline wind pressure is greater than the set negative pressure limit, it is considered that the current air pipeline wind pressure of the oil fume monitoring equipment in the current usage environment exceeds the normal applicable range, and the abnormal wind pressure status of the oil fume monitoring equipment at this time can be fed back to the remote cloud platform for alarm.

[0057] If the current air pipeline wind pressure is less than or equal to the set positive pressure limit, or the current air pipeline wind pressure is less than or equal to the set negative pressure limit, it is considered that the current air pipeline wind pressure of the oil fume monitoring equipment under the current usage environment is within the normal applicable range, and the first theoretical operating flow rate of the electromagnetic pump in the oil fume monitoring equipment is determined according to the current air pipeline wind pressure.

[0058] The first theoretical operating flow rate is the theoretical operating flow rate corresponding to the electromagnetic pump sucking the oil fume gas in the air pipeline, that is, the operating flow rate calculated corresponding to the oil fume gas sucked by the oil fume monitoring device under the current air pipeline wind pressure.

[0059] S120, after controlling the electromagnetic pump to absorb oil fume gas at a first theoretical operating flow rate, obtaining the actual operating flow rate of the electromagnetic pump, and determining whether to adjust the operating flow rate of the electromagnetic pump to absorb oil fume gas according to the first theoretical operating flow rate and the actual operating flow rate.

[0060] The actual operating flow rate is the operating flow rate corresponding to the oil fume gas sucked by the electromagnetic pump in the gas pipeline, which is detected in real time after the electromagnetic pump is controlled to suck the oil fume gas at the first theoretical operating flow rate.

[0061] The actual operating flow rate can be acquired through a flow detection module arranged in the oil fume monitoring device, that is, it can be acquired through real-time monitoring after the electromagnetic pump is controlled to absorb the oil fume gas at the first theoretical operating flow rate.

[0062] The current air pipeline wind pressure detected in real time by the flow detection module is the real-time flow rate of the solenoid pump sucking up the oil fume gas under the current use environment when the oil fume monitoring device is in the current installation position, that is, the actual operating flow rate.

[0063] On the basis of the above, whether it is necessary to adjust the operating flow rate of the electromagnetic pump to absorb the oil fume gas is determined based on the flow difference between the first theoretical operating flow rate and the actual operating flow rate. Specifically, if the flow difference between the first theoretical operating flow rate and the actual operating flow rate exceeds the first flow threshold, it is determined that there is an abnormality in the internal gas pipeline of the oil fume monitoring equipment; if the flow difference between the first theoretical operating flow rate and the actual operating flow rate does not exceed the first flow threshold, it is determined whether the flow difference exceeds the second flow threshold.

[0064] In this embodiment, when it is determined that the internal gas pipeline of the oil fume monitoring device is abnormal, that is, the internal resistance of the oil fume monitoring device is too large, the abnormal state of the internal gas pipeline of the oil fume monitoring device can be fed back to the remote cloud platform for alarm.

[0065] Furthermore, if the flow difference exceeds the second flow threshold, the operating flow of the electromagnetic pump to absorb the oil fume gas is adjusted; if the flow difference does not exceed the second flow threshold, the electromagnetic pump continues to be controlled to absorb the oil fume gas at the first theoretical operating flow.

[0066] The first flow rate threshold and the second flow rate threshold are selected and set according to the flow rate limit of the electromagnetic pump in the oil fume monitoring device to absorb the oil fume gas. This embodiment does not impose any restrictions on the specific values ​​of the first flow rate threshold and the second flow rate threshold. Optionally, the first flow rate threshold is greater than the second flow rate threshold.

[0067] S130. After determining the operating flow rate of the electromagnetic pump to absorb oil fume gas, determine the compensating operating flow rate of the electromagnetic pump according to the first theoretical operating flow rate and the actual operating flow rate, and determine the second theoretical operating flow rate of the electromagnetic pump according to the compensating operating flow rate and the first theoretical operating flow rate to control the electromagnetic pump to absorb oil fume gas at the second theoretical operating flow rate.

[0068] It can be known that after it is determined that the operating flow rate of the electromagnetic pump to absorb oil fume gas needs to be adjusted, the adjusted second theoretical operating flow rate is determined based on the first theoretical operating flow rate and the actual operating flow rate, and then the electromagnetic pump is controlled to absorb oil fume gas at the second theoretical operating flow rate. By analogy, after the electromagnetic pump is controlled to absorb oil fume gas at the second theoretical operating flow rate, the current operating flow rate of the electromagnetic pump is detected, and it is determined whether to adjust the operating flow rate of the electromagnetic pump to absorb oil fume gas based on the current operating flow rate and the second theoretical operating flow rate; if it is determined that the operating flow rate of the electromagnetic pump to absorb oil fume gas needs to be adjusted, the electromagnetic pump is controlled to absorb oil fume gas at the updated theoretical operating flow rate determined based on the second theoretical operating flow rate; conversely, if it is determined that there is no need to adjust the operating flow rate of the electromagnetic pump to absorb oil fume gas, it is determined to continue to control the electromagnetic pump to absorb oil fume gas at the first theoretical operating flow rate.

[0069] It can be understood that the theoretical operating flow of the electromagnetic pump and the corresponding actual operating flow monitored in real time can be used to flexibly adjust the operating flow of the electromagnetic pump to absorb oil fume gas in real time, thereby realizing dynamic regulation of the operating flow of the electromagnetic pump.

[0070] Among them, the second theoretical operating flow rate is the theoretical operating flow rate corresponding to the electromagnetic pump sucking the oil fume gas in the air pipeline, which is determined after determining the operating flow rate of the electromagnetic pump to absorb the oil fume gas, that is, the electromagnetic pump is controlled to switch from the first theoretical operating flow rate to the theoretical operating flow rate corresponding to the second theoretical operating flow rate to absorb the oil fume gas.

[0071] The current operating flow rate is the actual operating flow rate corresponding to the electromagnetic pump sucking the oil fume gas in the gas pipeline after controlling the electromagnetic pump to suck the oil fume gas at the second theoretical operating flow rate. Similarly, the current operating flow rate can be acquired by the flow detection module set in the oil fume monitoring device, that is, it is obtained by real-time monitoring after controlling the electromagnetic pump to suck the oil fume gas at the second theoretical operating flow rate.

[0072] The updated theoretical operating flow is the theoretical operating flow corresponding to the electromagnetic pump sucking the oil fume gas in the gas pipeline, which is determined after the operating flow of the electromagnetic pump is adjusted to absorb the oil fume gas. That is, the electromagnetic pump can be controlled to absorb the oil fume gas at the adjusted operating flow.

[0073] In this embodiment, the compensated operating flow rate of the electromagnetic pump is determined according to the flow difference between the first theoretical operating flow rate and the actual operating flow rate and the flow compensation coefficient, and the second theoretical operating flow rate of the electromagnetic pump is determined according to the following formula, specifically:

[0074] Q 运2 =Q 运1 +D / λ

[0075] Among them, Q 运2 is the second theoretical operating flow rate of the electromagnetic pump; Q 运1 is the first theoretical operating flow; D is the flow difference; λ is the flow compensation coefficient.

[0076] The technical solution of the embodiment of the present invention obtains the current air pipeline wind pressure when the oil fume monitoring device is in the current installation position, and determines the first theoretical operating flow rate of the electromagnetic pump in the oil fume monitoring device according to the current air pipeline wind pressure; after controlling the electromagnetic pump to absorb oil fume gas at the first theoretical operating flow rate, obtains the actual operating flow rate of the electromagnetic pump, and determines whether to adjust the operating flow rate of the electromagnetic pump to absorb oil fume gas according to the first theoretical operating flow rate and the actual operating flow rate; after determining to adjust the operating flow rate of the electromagnetic pump to absorb oil fume gas, determines the compensation operating flow rate of the electromagnetic pump according to the first theoretical operating flow rate and the actual operating flow rate, and determines the second theoretical operating flow rate of the electromagnetic pump according to the compensation operating flow rate and the first theoretical operating flow rate, so as to control the electromagnetic pump to absorb oil fume gas at the second theoretical operating flow rate. The present invention solves the problem that the current oil fume monitoring equipment cannot dynamically adjust the operating flow rate of the electromagnetic pump, which leads to inaccurate detection results.

[0077] Embodiment 2

[0078] Figure 2 This is a flow chart of a method for controlling a fume monitoring device provided in the second embodiment of the present invention. This embodiment provides an optional implementation method based on the above embodiment. Figure 2 As shown, the control method of the oil fume monitoring equipment includes:

[0079] S210, obtaining the current air pipeline wind pressure of the oil fume monitoring device at the current installation position.

[0080] S211. Determine whether the current air pressure in the gas pipeline is greater than the set positive pressure limit, or whether the current air pressure in the gas pipeline is greater than the set negative pressure limit. If so, execute step S212; if not, execute step S213.

[0081] S212. It is considered that the current air pipeline wind pressure of the oil fume monitoring equipment in the current use environment exceeds the normal applicable range.

[0082] S213, determining the first theoretical operating flow rate of the electromagnetic pump in the oil fume monitoring device according to the initial operating flow rate and the current air pipeline wind pressure, and executing step S214.

[0083] Exemplarily, when the current air pressure in the gas pipeline is positive, the difference between the initial operating flow and the positive pressure corrected operating flow determined based on the current air pressure in the gas pipeline is used as the first theoretical operating flow of the electromagnetic pump in the oil fume monitoring device, specifically:

[0084] Q 运1 =Q 初 -β positive W p

[0085] Among them, Q 运1 It is the first theoretical operating flow rate of the electromagnetic pump; Q 运2 is the second theoretical operating flow; β positive W p W is the positive pressure corrected operating flow rate; p is the current air pressure in the gas pipeline; β is the positive pressure correction coefficient; Q 初 It is the theoretical optimal operating flow rate of the electromagnetic pump.

[0086] When the current air pressure in the gas pipeline is negative pressure, the sum of the initial operating flow and the negative pressure corrected operating flow determined based on the current air pressure in the gas pipeline is used as the first theoretical operating flow of the electromagnetic pump in the oil fume monitoring device, specifically:

[0087] Q 运1 =Q 初 +β negative W p

[0088] Among them, β negative W p is the negative pressure corrected operating flow rate; β negative is the negative pressure correction coefficient.

[0089] It can be seen that the current air pipeline wind pressure W p Take its absolute value for corresponding calculation, the theoretical optimal operating flow rate Q of the electromagnetic pump 初 The oil fume monitoring device may be factory set, or may be selected and set by technicians in this field according to actual needs, and this embodiment does not impose any limitation on this.

[0090] Both the positive pressure correction coefficient β positive and the negative pressure correction coefficient β negative can be selected and set according to conditions such as the actual limit of the wind pressure of the electromagnetic pump, and this embodiment does not impose any limitation on this.

[0091] S214, after controlling the electromagnetic pump to absorb the oil fume gas at the first theoretical operating flow rate, obtaining the actual operating flow rate of the electromagnetic pump, and executing step S215.

[0092] S215. Determine whether the flow difference between the first theoretical operating flow and the actual operating flow exceeds the first flow threshold. If so, execute step S216; if not, execute step S217.

[0093] S216. Determine that there is an abnormality in the internal gas pipeline of the oil fume monitoring equipment.

[0094] S217, determine whether the flow difference between the first theoretical operating flow and the actual operating flow exceeds the second flow threshold, if so, execute step S218, if not, execute step S219.

[0095] S218. Determine the compensating operating flow of the electromagnetic pump according to the first theoretical operating flow and the actual operating flow, and determine the second theoretical operating flow of the electromagnetic pump according to the compensating operating flow and the first theoretical operating flow, so as to control the electromagnetic pump to absorb oil fume gas at the second theoretical operating flow.

[0096] Exemplarily, if the flow difference between the first theoretical operating flow and the actual operating flow exceeds the second flow threshold at this time, it is considered that the actual operating flow of the electromagnetic pump after controlling the electromagnetic pump to absorb oil fume gas at the first theoretical operating flow has not reached the optimal operating flow, and the theoretical operating flow of the electromagnetic pump needs to be further compensated and adjusted, that is, the compensated operating flow of the electromagnetic pump is determined according to the flow difference between the first theoretical operating flow and the actual operating flow and the flow compensation coefficient, and the second theoretical operating flow of the electromagnetic pump is determined according to the following formula, specifically:

[0097] Q 运2 =Q 运1 +D / λ

[0098] Wherein, D / λ is the compensation operation flow of the electromagnetic pump; D is the flow difference; λ is the flow compensation coefficient.

[0099] The flow compensation coefficient λ may be a factory setting of the oil fume monitoring device, or may be selected and set by those skilled in the art according to actual needs, and this embodiment does not impose any limitation on this.

[0100] It should be noted that after the electromagnetic pump is controlled to absorb oil fume gas at the second theoretical operating flow rate, the current operating flow rate of the electromagnetic pump is detected, that is, the execution returns to step S214. At this time, step S214 is to obtain the current operating flow rate obtained by detecting the electromagnetic pump when the electromagnetic pump is controlled to absorb oil fume gas at the second theoretical operating flow rate. Further, the subsequent steps S215 to S217 are executed, but it is necessary to determine whether to adjust the operating flow rate of the electromagnetic pump to absorb oil fume gas according to the current operating flow rate and the second theoretical operating flow rate. On this basis, according to the result of determining whether to adjust the operating flow rate of the electromagnetic pump to absorb oil fume gas, it is determined whether to continue to control the electromagnetic pump to absorb oil fume gas at the second theoretical operating flow rate, or to control the electromagnetic pump to absorb oil fume gas at the updated theoretical operating flow rate determined based on the second theoretical operating flow rate, thereby realizing cyclic dynamic and flexible adjustment of the operating flow rate of the electromagnetic pump, and making the operating flow rate of the electromagnetic pump relatively stable.

[0101] S219, continue to control the electromagnetic pump to absorb the oil fume gas at the first theoretical operating flow rate.

[0102] The basic scheme of the embodiment of the present invention solves the problem that the flow of the electromagnetic pump cannot be dynamically adjusted by judging the current air pipeline wind pressure and the theoretical operating flow rate and the actual operating flow rate of the electromagnetic pump when the oil fume monitoring device is currently installed. Dynamic and flexible adjustment of the operating flow rate of the electromagnetic pump is achieved. At the same time, based on the detection of the current air pipeline wind pressure and the theoretical operating flow rate and the actual operating flow rate, the current use environment and the state of the internal air path of the oil fume monitoring device are judged, so as to timely discover possible faults of the oil fume monitoring device, thereby extending the service life of the oil fume monitoring device.
