[0014] Figure 1 It is a schematic diagram of a module of the present invention;

[0015] Figure 2 It is the main working flow diagram of the modules involved in the present invention. DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] See also Figure 1 and Figure 2 The present invention provides a generator set starting signal control system, the generator set starting signal control system comprises:

[0018] The driving module includes a starting unit and a working unit. The starting unit starts the working unit. After the working unit is started, it will enter a stable working condition and generate output current. If the generator set is a diesel generator set, the starting unit and the working unit correspond to the starting switch and the diesel generator respectively. When starting, the diesel generator is started manually or remotely by the starting switch, and enters the power generation work under different working conditions (idling condition, acceleration condition, etc.).

[0019] The detection module is used to detect the stability of the current output environment of the generator set and obtain a stable value G. In this embodiment, the detection module includes a humidity sensor for detecting the humidity of the environment; and the corresponding stable value G includes the humidity Txt obtained by the humidity sensor.

[0020] A starting energy storage unit, which provides the energy required for the starting unit to work, is usually an energy storage battery, and the energy storage battery is connected to the starting switch;

[0021] The control module includes a circuit breaker protection unit, which controls (blocks or conducts) the first path output by the working unit; when the starting unit drives the working unit to start, the control module obtains the buffer time according to the stable value G (the buffer time is the evacuation time given to the staff before the working unit outputs current). When the time after the equipment is started is within the buffer time, the first path is in a blocked state, and no current is output in this state. When the time after the equipment is started is outside the buffer time, the first path enters a conducting state, and the equipment enters an output state.

[0022] The control module calculates the buffer time through the humidity Txt;

[0023] The buffer time S is calculated according to the following formula:

[0024] If Txt>Txt0 (humidity is higher than the standard value), that is, (Txt-Txt0)>0, the buffer time S is: S=S0+(Txt-Txt0)×V 实 ×α;

[0025] If Txt≤Txt0 (humidity is lower than / equal to the standard value), that is, (Txt-Txt0)≤0, the buffer time S is: S=S0;

[0026] The Txt0 is a humidity comparison parameter set in the control module (this value is manually input), S0 is the initial setting time (this value is manually input), V 实 is the actual voltage value output by the first channel, and α is the unit conversion coefficient.

[0027] In the above embodiment, the actual voltage value V output by the first path 实 =220V, or as shown in the third embodiment, V 实 is a variable value. At this time, the buffer time S is affected by the humidity Txt and the actual voltage value V 实 The influence of two variables.

[0028] In a second embodiment, based on the above embodiment, the control module further includes an air breakdown voltage test unit, which includes an output end connected to the starting energy storage unit and a receiving end provided with a voltage sensor, with air medium between the two;

[0029] During the test, the air breakdown voltage test unit controls the output end to release the breakdown voltage V1 at a predetermined frequency, wherein the breakdown voltage V1 can be a preset fixed value (a voltage of a fixed value) or the breakdown voltage V1 is determined by increasing by a predetermined increase value each time it is released by 0V or a predetermined initial value (for example, the initial value is 10V) at the output. For example, if the predetermined increase value is 10V and the initial value is 10V, then the breakdown voltage V1 is released each time as 10V, 20V, 30V..., up to the maximum voltage of 220V.

[0030] When the receiving end stably receives the voltage value, record the voltage as V 标 (Air breakdown voltage of the environment where the equipment is located) means that the air in this environment has been broken down, which poses a great risk of electric leakage. At this time, you can choose to stop the power supply or sound an alarm.

[0031] In the third embodiment, the control module includes a circuit breaker assembly (i.e., a circuit breaker), which is generally manually switched on (pressed to switch on);

[0032] After the starting unit drives the working unit to start, the circuit breaker controls the first path to be in an open state. When the circuit breaker is manually opened, the time after the equipment is started enters the buffer time. After the time after the equipment is started enters beyond the buffer time, the first path is connected.

[0033] Furthermore, during a single start, the control module controls the output voltage of the first path to be V 标 , if V 标 If the normal power supply requirement cannot be met, the first single press can be continued after the first press, and the control module controls the output voltage of the first channel to V 实 , V 实 =V 标 +V 加 ×i; until V 实 Meet the normal power supply needs.

[0034] V 加 ×i is the voltage increase after the i-th press, V 加 is a predetermined growth value, wherein the predetermined growth value V 加 It is 10V~50V.

[0035] In addition, when the first path is in a blocked state, the output current enters the startup energy storage unit through the second path to achieve energy recycling.

[0036] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
