Embodiment
A kind of unmanned engine starting system (1), it can automatically perform test by having got rid of for the needs of manpower, consists essentially of:
-at least one electronic control unit (ECU) (2),
-at least one first box (3), it is connected to the contact circuit of vehicle and is suitable for controlling the starting of described motor (M) and stopping,
-at least one very first time relay (3.1),
-at least one second time relay (3.2),
-at least one first contactor (3.3),
-at least one second box (4), acceleration and deceleration that it is connected to motor (M) speed control inputs and is suitable for control engine (M),
-at least one the 3rd time relay (4.1),
-at least one second contactor (4.2).
In unmanned engine starting system of the present invention (1), after starting, can make motor (M) wait in idling speed, continue certain period and then accelerate to top speed, and after top speed operation continues scheduled time slot, decelerate to idling speed and moving scheduled time slot (cycle period) afterwards, can make it stop.This process is known as complete circulation and allows motor (M) to wait for the scheduled time slot between circulation.In order to make process avoid depending on manpower, by utilizing electronic control unit (2) to prepare automatic signal control unit.
In a preferred embodiment of the invention, the first box (3) comprises very first time relay (3.1), second time relay (3.2) and the first contactor (3.3) and preferably powers with 220V; The second box (4) comprises the 3rd time relay (4.1) and the second contactor (4.2) and preferably powers with 24V Vehicular battery, and the first box (3) is integrated each other ground work with the second box (4) and sent and order (Fig. 1) to electronic control unit (2).
The first box (3) of controlling the startup of motor (M) and stop is connected to the contact circuit of vehicle.Signal sends to the first contactor (3.3) by very first time relay (3), the first contactor (3.3) is arranged in the first box (3) and conventionally in an open position, and therefore, the first contactor (3.3) is switched to operating position, and (M) thus allows to pilot engine.In the time that cycle period finishes, be arranged in the very first time relay (3.2) of the first box (3) to the first contactor (3.3) transmitted signal, and therefore the first contactor (3.3) in the close position is switched to open position and thereby has stopped motor (M).
Second box (4) that can make motor (M) accelerate and to slow down is connected to motor (M) speed control inputs.For motor (M) is accelerated, the 3rd time relay (4.1) is to common the second contactor (4.2) transmitted signal in an open position, and therefore the second contactor (4.2) is switched to operating position and motor (M) is accelerated.For motor (M) is slowed down, the 3rd time relay (4.1) is to the second contactor (4.2) transmitted signal in the close position, and therefore the second contactor (4.2) is switched to open position and motor (M) is slowed down.
In one embodiment of this invention, preferably at after the first box (3) power supply 15 seconds, start operation as the very first time relay (3.1) of the basic counter of the first circulation (it will continue 85 seconds) and to the electronic control unit (2) of motor (M) and the main power line of the second box (4) transmission activation signal.After this starts about 9 seconds, starter signal has started motor (M) and after approximately 14 seconds, for motor (M) is switched to aero mode, be sent to the electronic control unit (2) of motor (M) from the signal of the 3rd time relay (4.1) in the second box (4).Although motor (M) operation, from the signal cut of second time relay (3.2) in the first box (3) circuit of starter.Meanwhile, utilize the signal from the second box (4), motor (M) speed increases.
After arriving top speed, motor (M) continues specific time period with top speed operation, and make the operation of the 3rd time relay (4.1) converse, the 3rd time relay (4.1) is arranged in the second box (4) and it sends closure/opening signal simultaneously, motor (M) is switched to deceleration mode, and after certain period, motor (M) arrives idling speed and continues and continues specific time period in idling speed operation.After the signal of very first time relay (3.1) (it is the counter that first starts operation in the first box (3)) is cut off, (the motor (M) that rests on idling speed stops, complete cycle period), and in the time being arranged at second time relay (3.2) in the first box (3) and starting to count, it remains on stop position and continues specific time period and be switched to idle mode to start next circulation for waiting for.This circulation continuous ground repeats self, and does not rely on people.
