Control device for general purpose engine

A control device for a general purpose engine in a system, the system including:

• a plurality of liquid pumps, including a first liquid pump and a second liquid pump, that are placed to be spaced from one another,
• a plurality of general purpose engines, including the general purpose engine and other general purpose engines, for driving the plurality of liquid pumps respectively, and
• a plurality of control devices, including the control device and other control devices, for the plurality of general purpose engines respectively,
• wherein liquid existing in a first place is transferred to a second place by transferring the liquid through the liquid pumps and at least one container alternately,
• the control device comprising:
• a communication interface configured to communicate with the other control devices for the other general purpose engines;
• a start instruction information sending processor configured to send, after the first liquid pump that is to be driven by the general purpose engine that is to be controlled by the control device is started to be driven, start instruction information to a second control device of the other control devices that drives the second liquid pump placed adjacent to a downstream side of the first liquid pump in a transferring direction of the liquid to instruct the second control device to start driving of the second liquid pump when information indicating a driving record of the first liquid pump reaches a threshold,
• wherein the second liquid pump is started to be driven by the second control device that receives the start instruction information;
• a fuel amount detecting processor configured to detect an amount of fuel remaining in the general purpose engine;
• and
• a stop instruction information sending processor configured to send stop instruction information to control devices of the other control devices that respectively drive all liquid pumps of the plurality of liquid pumps that are placed on an upstream side of the first liquid pump in the transferring direction of the liquid when the amount of fuel is reduced to be below a threshold while the first liquid pump is being driven,
• wherein driving of all the liquid pumps on the upstream side is stopped by the control devices that receive the stop instruction information.
