Description
Technical Field
The invention relates to the technical field of generators, in particular to an engine generator and a control method and a control system thereof.
Background
The small emergency generator is generally suitable for occasions such as families, small businesses and the like, a general engine and the like are mostly used for power, the displacement of the internal combustion engine is relatively small, and gasoline is mostly used as fuel. When the engine generator is used, the generator is often placed in a relatively small and relatively closed space such as a basement or a sundry room, and carbon monoxide (CO) is contained in exhaust gas generated in the working process of the generator, so that the CO can be accumulated in a limited space, and when the concentration of the CO reaches a certain limit, a person in the space may be poisoned by the CO.
In order to prevent the harm, the prior art is provided with a CO alarm, the CO alarm acquires the concentration of CO gas in the environment in real time, and when the concentration of CO reaches a preset safety threshold, the alarm is given and an engine in the alarm is flamed out.
However, the real-time acquisition is to acquire data once every preset time, and the preset time is short, so that the real-time detection effect is considered to be achieved. However, in actual testing, the CO alarm has a certain time length between two adjacent data acquisitions, and it also takes a certain time for the data to be fed back to the control system and processed, that is, it takes a certain time for the signal to be acquired and responded.
Meanwhile, in the practical process, the inventor finds that: in the engine generator in the prior art, the CO alarm is specially designed for the engine with certain displacement, the applicable displacement range is narrow, and the CO alarm cannot be used for the engine with a larger or smaller displacement range, and the reason for exploring the CO alarm is as follows: in a certain space, under an ideal condition, the rate of the engine generating CO is increased linearly, please refer to fig. 1, wherein L1, L2 and L3 represent the rate lines of the engine generating CO with three displacements of large displacement, medium displacement and small displacement respectively, as can be seen from fig. 1, Δ P1 > Δ P2 > Δ P3, that is, the larger the displacement of the engine is, the larger the increment Δ P of the concentration of CO in the same interval time Δ t is.
Therefore, the engine with larger displacement tends to generate more CO at a higher speed in a certain space, and the acquisition and response of the signal take a period of time, and the engine can continuously generate a large amount of CO in the period of time, so that the CO concentration in the environment exceeds a preset safety threshold when a specially designed CO alarm gives an alarm, the life safety of personnel in the environment is threatened, and the problem that the alarm is delayed when the response of the alarm is not timely occurs.
In summary, how to improve the universality of the CO alarm, so that the CO alarm has higher alarm accuracy when being matched with engines with different displacement, and further improves the safety of users is a problem to be solved by technical personnel in the field.

Referring to fig. 2, the present application provides a control method of an engine generator including the steps of:
and step S1, acquiring the current CO concentration.
Specifically, the current CO concentration refers to a CO concentration measured in a certain space during the operation of the engine generator, and the current CO concentration is an actual measured value and can be determined by real-time detection of the detection device 3.
Step S2, the CO concentration increase rate is acquired.
Specifically, the CO concentration increase rate refers to the CO concentration increase per unit time, and in the actual detection process, may be determined in the following manner: and acquiring the CO concentration increment in the preset detection time period, and determining the CO concentration increase rate through the CO concentration increment and the preset detection time period. More specifically, the detection device 3 may be used to detect the current CO concentration at a first time, and send the current CO concentration to the controller 4, and then the detection device 3 detects the current CO concentration again at a second time, and sends the current CO concentration to the controller 4 again, where a time length between the first time and the second time is a preset detection time period, and a ratio of a difference between the two times of CO concentrations to the preset detection time period is a CO concentration increase rate.
Step S3, determining a target concentration threshold; the preset increasing rate range is divided into at least two reference intervals, each reference interval corresponds to a preset concentration threshold, the preset concentration threshold is in negative correlation with the median of the reference interval, and the target concentration threshold is the preset concentration threshold corresponding to the reference interval in which the CO concentration increasing rate is located.
Specifically, the preset increase rate range may be determined by performing experiments on existing products, for example, selecting a plurality of engines with different displacement volumes, measuring the CO concentration increase rate of each engine, and setting the set of the measured minimum CO concentration increase rate to the maximum CO concentration increase rate as the preset increase rate range. The preset increasing rate range is divided into a plurality of reference intervals in the order from small to large, and no intersection exists among the reference intervals. The plurality of reference intervals and the preset concentration threshold corresponding to each reference interval are preset in the controller 4 by a designer according to design requirements and in consideration of various factors.
After the CO concentration increase rate is obtained, determining which reference interval the current CO concentration increase rate is in by judging or other ways, and setting a preset concentration threshold corresponding to the reference interval as a target concentration threshold.
In step S4, when the current CO concentration reaches the target concentration threshold value, the engine 1 of the engine generator is controlled to stop operating.
Specifically, the manner of controlling the engine 1 to stop running is selected in various ways, for example, the ignition device of the engine 1 may be controlled to stop igniting, and specifically, the extinguishing line may be communicated so as to stop igniting the ignition device; or controls the fuel supply device of the engine 1 to stop supplying fuel; of course, other modes can be selected, and the engine 1 can be controlled to stop.
Optionally, the control method may further include step S5:
step S5, when the current CO concentration reaches the target concentration threshold, controls the alarm 5 to give an alarm to prompt the user.
In steps S1 to S4 in the present application, steps S2, S3, and S4 need to be executed in the order from first to last, while the specific execution order of step S1 is not limited, and step S1 may be executed before step S4.
In practical application, for an engine 1 with a certain displacement, the larger the displacement is, the larger the CO concentration increase rate during operation is, the larger the median value of a corresponding reference interval is, and the negative correlation is formed between the median value of the reference interval and a preset concentration threshold value, namely, the smaller the finally selected target concentration threshold value is. Therefore, the control method can control the engine 1 to stop in advance or in a delayed mode according to the increase rate of the CO concentration, the purpose of avoiding the CO concentration exceeding the standard is achieved, the problem that the CO gas concentration in the actual space far exceeds the target concentration threshold value when the engine 1 is shut down under the running condition of the large-displacement engine 1 is solved, and therefore the safety of users is improved.
