According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are in a very simplified form and use non-precise scales, only for the purpose of facilitating and clearly assisting in explaining the implementation manners of the present invention. In order to make the objectives, features and advantages of the present invention more obvious and understandable, please refer to the accompanying drawings. It should be noted that the structures, scales, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention. Therefore, they do not have technical essence. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present invention can produce and the objectives that can be achieved, should still fall within the scope covered by the technical content disclosed by the present invention.

[0066] Please refer to Figure 5 , in the start control system of the generator set in this embodiment, the first control system 1 and the second control system 2 connected to the first control system 1, and the output ends of the second control system 2 are respectively connected to the first start group 300 and the second start group 301.

[0067] Specifically, the first control system 1 receives external input signals, receives start or alarm signals from the second control system 2, and outputs the start conditions of each start group to remote users or a host computer other than remote users. Among them, the external input signals are power failure faults of the main power supply, fire signals, manual maintenance tests, etc. that require standby generator sets to generate electricity.

[0068] Further, please refer to Figure 8 The first control system 1 is preferably a first single-chip microcomputer, and the first single-chip microcomputer has a communication module 100. The communication module 100 includes several communication interfaces. Please refer to Figure 7 and Figure 8 The communication interfaces include a USB interface 1000, an RS485 interface 1001, an RS232 interface 1002, a CAN communication interface 1003, an Ethernet interface 1004, and a WIFI interface 1005.

[0069] Specifically, by providing multiple communication interfaces, communication and interaction with different devices can be achieved. Specifically, the setting of the USB interface 1000 enables the first single-chip microcomputer to be connected to a PC, so that on-site users can view the opening and closing conditions of each startup group through the PC device. At the same time, the USB interface 1000 can also input external input signals into the first single-chip microcomputer for processing, that is, send relevant instructions such as a motor startup instruction and an emergency stop instruction.

[0070] Further, the above Ethernet interface 1004 can achieve interaction with remote users, and the above WIFI interface 1005 can achieve connection with mobile terminals, such as smart phones, smart tablets, and wearable devices.

[0071] Further, the above RS485 interface 1001 and RS232 interface 1002 can be connected to external devices or remote devices that also have RS485 interfaces and RS232 devices.

[0072] Further, please refer to Figure 6 and Figure 7 The second control system 200 is preferably a second single-chip microcomputer. The second single-chip microcomputer has the same model as the first single-chip microcomputer. The second single-chip microcomputer is used to process and control external signals. The second single-chip microcomputer has a data signal acquisition module 200. The data signal acquisition module is used to collect data of sensors in each startup group and transmit the collected data to the first single-chip microcomputer through the SPI protocol.

[0073] Further, please refer to Figure 6 and Figure 7 In this embodiment, the data signal acquisition module specifically includes four interfaces, namely a first analog interface 200, a second analog interface 201, a third analog interface 202, and a fourth analog interface 203. Specifically, the first analog interface 200 is used to collect the flywheel speed signal, the second analog interface 201 is used to collect the battery voltage, the third analog interface 202 is used to collect the gas tank pressure, and the fourth analog interface 203 is used to collect the engine ignition speed.

[0074] Further, please continue to refer to Figure 6 and Figure 7 , the second single-chip microcomputer is also electrically connected to an alarm module 204, a display module 205, and a storage module 206 respectively. Alarm information can be indicated through the alarm module 204, the opening and closing information of the relevant startup group can be displayed through the display module 205, and the opening and closing information of the startup group and the system-set alarm values can be stored through the storage module 206. The opening and closing information includes information such as the time, date, and reason for opening and closing, and the system-set alarm values include battery voltage values, gas tank pressure values, ignition speed values, etc.

[0075] Correspondingly, the present invention also provides a startup control method for a generator set according to the above startup control system of the generator set, including the following steps:

[0076] The first control system 1 receives input signals. Specifically, the input signals are at least one, and the input signals are input signals from a host computer and / or output signals of a second control system. The host computer is preferably a PC. Of course, in other embodiments of the present invention, the host computer can also be a mobile terminal, an ECU, and an electronic device capable of accessing the Ethernet through TCP / IP other than a PC. The present invention does not make further limitations in this regard.

[0077] Please continue to refer to Figure 1 , the first control system 1 outputs an instruction to the second control system 2 according to the above input signals, and the second control system 2 selects a startup mode according to the instruction to start the first startup group 300 and / or the second startup group 301. Specifically, the startup mode includes any one of a first mode, a second mode, or a third mode.

[0078] Specifically, the first mode is mainly applied to conventional occasions or normal standby states. The second mode is mainly used in data centers, that is, places that need to ensure power supply, so as to ensure the reliability of power supply. The third mode is used for emergency states such as fire fighting, and it is used to start the first startup group 300, the second startup group 301, and the nth startup group.

[0079] Please continue to refer to Figure 1 , the first startup group 300 and / or the second startup group 301 feedback at least one set of data signals to the second control system 2, and the second control system 2 exchanges signals with the first control system 1 according to the data signals, so that the first control system determines whether the first startup group 300 and / or the second startup group 301 is started. The above data signals include any one or more of a rotation speed signal, a battery voltage signal, a current signal, and a pressure signal.

[0080] Correspondingly, in other embodiments of the present invention, the startup groups for starting the second control system 2 are not limited to the first startup group 300 and the second startup group 301, and can be any startup group other than the first startup group 300 and the second startup group 301, that is, the nth startup group.

[0081] Specifically, the above instructions can also be single instructions or non-single instructions. The single instruction can control the first startup group 300 or the second startup group 301 through a single instruction, or can also control the first startup group 300, the second startup group 301, and any two startup groups other than the first startup group 300 and the second startup group 301 through non-single instructions. The present invention does not make further limitations in this regard.

[0082] Please refer to Figure 2 and Figure 7 , specifically, the startup control steps of the second control system 2 in the first mode are described as follows:

[0083] A1: Select the first startup group 300 or the second startup group 301. In this embodiment, the first startup group 300 is selected as an example for illustration.

[0084] A2: The first startup group 300 receives a startup signal. Specifically, the first single-chip microcomputer in the first control system 1 outputs a startup instruction, the second single-chip microcomputer receives the startup instruction and selects the first mode, and the second single-chip microcomputer outputs an instruction to the first startup group 300.

[0085] A3: Determine whether the first startup group 300 is started. If yes, jump to step A4; if not, jump to step A5.

[0086] A4: The first analog interface 200, the second analog interface 201, the third analog interface 202, or the fourth analog interface 203 in the second single-chip microcomputer receives the sensor data information fed back by the first startup group. After determining that the first startup group 300 is successfully started, a startup success instruction is output to the first control system 1, that is, the first single-chip microcomputer.

[0087] A5: If it is determined that the first startup group 300 is not successfully started, end the startup control steps in this first mode. At the same time, the second single-chip microcomputer outputs a startup failure signal to the first single-chip microcomputer. The first single-chip microcomputer receives the startup failure signal and can feedback it to a remote user through the network, or can also feedback it to the upper computer. At the same time, the second single-chip microcomputer can also display an alarm through the alarm module 204 and feedback alarm information according to the display module 205.

[0088] Correspondingly, please refer to Figure 5 , taking the first startup group 300 as an electric motor as an example, the specific steps for determining whether the first startup group 300 is started are as follows:

[0089] S1: The first startup group 300 receives a second mode instruction signal output from a second single chip microcomputer.

[0090] S2: Determine whether there is a locking signal or an alarm signal. If yes, jump to step S4; if no, jump to step S3;

[0091] S3: The second single-chip microcomputer detects whether the engine in the first startup group 300 is running; specifically, the second single-chip microcomputer collects the speed data received by the speed sensor at the engine flywheel through the first analog interface 200. If yes, jump to step S4, if not, jump to step S5.

[0092] S4: Output alarm signal and locking signal. Specifically, the second single-chip microcomputer fails to collect the sensor data collected by the speed sensor at the flywheel. The second single-chip microcomputer outputs an alarm signal to the first single-chip microcomputer and can also display the alarm through the alarm module 204, and feedback the alarm information according to the display module 205. The display module 205 can be a touch screen display.

[0093] Similarly, while outputting the alarm signal, the first single-chip microcomputer outputs a blocking signal to the second single-chip microcomputer, and the second single-chip microcomputer outputs the blocking signal to the first start group 300, the second start group 301 or the nth start group. The blocking signal is an emergency stop command, that is, all start groups are prohibited from starting. Even if the first start group, the second start group, and the nth start group receive the blocking signal during operation, they will immediately exit, and the above blocking signal is also displayed on the display module 205. The blocking signal needs to be reset before it can be released. Preferably, the above blocking signal can be issued when the emergency stop button is pressed or when the engine fuel in a certain start group is missing.

[0094] S5: If it is detected that the engine in the first starter group 300 is running, then it is detected whether the battery voltage in the first starter group 300 is sufficient. Specifically, the second single-chip computer detects the battery voltage through the voltage sensor, and collects relevant battery voltage data to the second single-chip computer according to the second analog interface 201. The second single-chip computer simultaneously calls out the relevant system setting alarm value from the storage module 206. When the detected battery voltage value is less than the system alarm setting value, it jumps to step S6. Similarly, when the detected battery voltage value is greater than the system alarm setting value, it jumps to step S7.

[0095] S6: When the detected battery voltage value is less than the system alarm setting value, the second single chip microcomputer outputs a startup failure signal to the first single chip microcomputer. The second single chip microcomputer can also display an alarm through the alarm module 204 and feedback the alarm information through the display module 205.

[0096] S7: When the detected battery voltage value is greater than the system alarm set value, the second single-chip microcomputer starts the relevant relay through the switch module 201, closes the starting circuit to make the motor or starter work. Among them, the above switch module 201 belongs to a part of the second single-chip microcomputer 2. The second switch module 201 is used to control the starting relay or solenoid valve and to implement other reset actions. The starting of the above relay and solenoid valve is to control the starting of the starter or motor in the starting group. Similarly, the closing of the relay and solenoid valve is to control the closing of the starter or motor in the starting group.

[0097] S8: Detect whether the rotational speed value during the operation of the above engine exceeds the system alarm set value. Specifically, the second single-chip microcomputer collects the engine ignition rotational speed data through the fourth analog interface 203, and the second single-chip microcomputer retrieves the system set alarm value of the ignition rotational speed from the storage module 206 for comparison. If the engine ignition rotational speed is greater than the system set alarm value, jump to step S9; if not, jump to step S10.

[0098] S9: The rotational speed start is successful. The second single-chip microcomputer outputs a start success signal to the first single-chip microcomputer (jump to step S12). The first single-chip microcomputer receives the start success signal and can feedback it to the remote user through the network, or can also feedback it to the upper computer.

[0099] S10: Considering that the motor is an electric motor and the electric motor in the first starting group 300 is of short-time duty system, so if the engine ignition rotational speed is less than the system set alarm value, enter the judgment process. The second single-chip microcomputer judges whether the repeated execution times of steps S2 to S8, that is, the loop times, exceed the system alarm set value. If so, jump to step S11; if not, continue to repeatedly execute steps S2 to S8.

[0100] S11: If it is detected that the repeated execution times from step S2 to step S8 have reached the system alarm set value, but the first starting group 300 still fails to start successfully, the second single-chip microcomputer outputs a start failure signal and an alarm signal.

[0101] Correspondingly, the present invention also provides a second mode. The second mode belongs to a switching mode. Taking the first starting group 300 as an example, the starting steps of the second mode are as follows:

[0102] B1: The first starting group 300 that receives the start signal works.

[0103] B2: Judge whether the first starting group 300 starts; if so, jump to step B3; if not, jump to step B4. The judgment process of the start of the above first starting group 300 has been described in detail in the first mode and will not be further described here.

[0104] B3: It is detected that the first startup group 300 has been started. The second single-chip microcomputer outputs a startup success signal to the first single-chip microcomputer, and the first single-chip microcomputer also feeds back the startup success signal to the remote user or on-site user.

[0105] B4: Since the startup of the first startup group 300 fails, at this time, the second single-chip microcomputer selects the remaining startup groups that are online and available for operation. Taking the second startup group 301 as an example, the second single-chip microcomputer outputs a startup signal to the second startup group 301.

[0106] B5: Determine whether the second startup group 301 has been started; if so, jump to step B6; if not, jump to step B7:

[0107] B6: End the startup; specifically, when the second startup group 301 starts successfully, the second single-chip microcomputer outputs a startup success instruction to the first single-chip microcomputer, and then the first single-chip microcomputer feeds back the startup success signal to the remote user or on-site user.

[0108] B7: Output a startup failure signal and an alarm signal to the first single-chip microcomputer. Specifically, when the second startup group 301 fails to start successfully, at this time, the second single-chip microcomputer outputs a startup failure signal and an alarm signal to the first single-chip microcomputer, and then the first single-chip microcomputer feeds back the startup success signal to the remote user or on-site user.

[0109] Correspondingly, please refer to Figure 4 In addition, the present invention also provides a third mode, which belongs to a cyclic mode. Taking the first startup group 300 as an example, the startup steps for selecting the third mode are as follows:

[0110] C1: The first single-chip microcomputer outputs a startup instruction to the second single-chip microcomputer, and the second single-chip microcomputer outputs a startup signal to the first startup group 300.

[0111] C2: Determine whether the first startup group 300 has been started; if so, jump to step C3, if not, jump to step C4;

[0112] C3: The first startup group 300 has been started. The second single-chip microcomputer outputs a startup success signal to the first single-chip microcomputer, and the first single-chip microcomputer feeds back the startup success signal to the remote user or on-site user, and ends the startup step.

[0113] C4: The first single-chip microcomputer outputs a startup instruction to the second single-chip microcomputer, and the second single-chip microcomputer outputs a startup signal to the second startup group 301 through the switch module, thereby enabling the second startup group 301 to work.

[0114] C5: Determine whether the second startup group has been started; if so, jump to step C6, if not, repeat steps C2 to C7;

[0115] C6: The second startup group 301 has been started. The second single-chip microcomputer outputs a startup success signal to the first single-chip microcomputer, and the first single-chip microcomputer feeds back the startup success signal to the remote user or on-site user, ending the startup procedure.

[0116] C7: Determine whether the loop count of steps C1 to C5 exceeds the set value. If so, jump to step C8; if not, repeat steps C1 to C5.

[0117] C8: The second single-chip microcomputer outputs a startup failure signal and an alarm signal to the first single-chip microcomputer. Specifically, when the second startup group 301 still fails to start successfully, at this time, the second single-chip microcomputer outputs a startup failure signal and an alarm signal to the first single-chip microcomputer, and then the first single-chip microcomputer feeds back the startup success signal to the remote user or on-site user.

[0118] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0119] The above-described embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
