Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
113 words
A control system for controlling industrial use vehicles, comprising: travel signal input means for inputting an output signal of an accelerator for travel; cargo-handling signal input means for inputting a cargo-handling signal; monitor voltage input means for detecting a voltage at each monitor point to input a detected signal; sensor input means for inputting an output signal of each sensor; monitor input means for inputting an output signal of each monitor; and a microprocessor controller for generating a predetermined control signal according to the output signals of each of said travel signal input means, said cargo-handling signal input means, said monitor voltage input means, said sensor input means, and said monitor input means.
Claim 2
Dependent Claim
113 words
A control system for controlling industrial use vehicles, comprising: travel signal input means for inputting an output signal of an accelerator for travel; cargo-handling signal input means for inputting a cargo-handling signal; monitor voltage input means for detecting a voltage at each monitor point to input a detected signal; sensor input means for inputting an output signal of each sensor; monitor input means for inputting an output signal of each monitor; and a microprocessor controller for generating a predetermined control signal according to the output signals of each of said travel signal input means, said cargo-handling signal input means, said monitor voltage input means, said sensor input means, and said monitor input means.
Claim 3
Dependent Claim
64 words
A control system as claimed in Claim 1, in which when receiving the output signals of said travel signal input means and said cargo-handling signal input means, said microprocessor controller sets a reference time point in a fixed period generated therein at an OFF point of one of said travel signal or said cargo-handling signal, and sets at an ON point of the other.
Claim 4
Dependent Claim
65 words
A control system as claimed in Claim 1, in which said microprocessor controller receives an output signal of said travel signal input means, and checks whether or not a plugging current exceeds a preset value within a predetermined period when a travel chopper starts to operate, and produces a control signal to select a regeneration brake mode when said plugging current exceeds said preset value.
Claim 5
Dependent Claim
51 words
A control system as claimed in Claim 1, in which said microprocessor controller receives a voltage of a battery contained in said monitor voltage input means, and produces a control signal to apply a fixed average exciting voltage to an exciting coil of each contact even if a battery voltage varies.
Claim 6
Dependent Claim
41 words
A control system as claimed in Claim 1, in which said microprocessor controller has a self-check function, and a display section is provided that is capable of displaying the result of the self-check or the monitor with a series of characters.
