Preignition for motorcycles I552
Device comprises from central part (CPU 80C552) and consoles. Console is separable also appliance after parametring can will work without her.
Across the console possibly is:
Reprogram angle preignition (point along the point or linearizaciom between a few points)
Monitor actual number turning and angle preignition
Monitor acceleration (dn / dt)
Monitor angle between entry channel (because of control of mechanical fixing)
Monitor condition input and output
Central part consists of two channel complex processing entry signal. Every channel has timer for flickering and exit driver with temperature compensed current limit. When CPU not execute preignition then output completely transparent for entry signal.
CPU board using software-execute the measurement and calculating points preignition, and at the same time can given data on console. Characteristics regulations is identical as at versions I2051 with AT89C2051 with this that I552 has:
finer resolution measurements number turning (i.e. 3700 points in table preignition) from 915 to 19000 turning in minute
much more stable point preignition because of usage of hardware of processors 80C552
usage possibility of separable console for adjusting
more additional possibilities because of larger programmatical memory
is predicted for channel who moves for 180° (for V-motors does not work)
simulates other output channel (slave) when executes preignition (915..19000 turns in the minute) when does have not the active entrance on slave channel.
board has larger size
Making on order.
Price of the finished two channel device (central part, console, entry interface) is 3000 HRK (400 eura)
Alternative possibilities of usage of complex:
Frequency measurement or the number turning
Measured times or phase angle between two entry channel (in the continuous regime) in area 1000 - 19000 turning in the minute
Measurement of angle to the closednesses of platinums display in degrees or percentage
Display accelerations or retardations (accelerations or deceleration)
