The structured flowchart of the IO control system of the engineering truck that Fig. 1 provides for the embodiment of the present invention.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
The structural representation of the IO control system of the engineering truck that Fig. 1 provides for the embodiment of the present invention; As shown in Figure 1, this IO control system comprises: telltale and at least one IO control unit, described IO control unit is arranged on acquisition of signal position on engineering truck or/and signal outgoing position, automatic collection signal is sent to CAN and carries out output from reading information CAN and controls, and is connected between described IO control unit and described telltale by CAN; The signal that described telltale is used for described IO control unit sends carries out calculation process; Described telltale and at least one IO control unit described are distributed frame.
The distributed I/O control system comprising aforementioned display device and at least one IO control unit described can subregional Gather and input signal and export control signal, transmitted by CAN between all IO control units, IO control unit is arranged in acquisition of signal or exports the position of comparatively concentrating, the quantity of electric wire can be reduced greatly, reduce the difficulty of trouble diagnosing and investigation; Meanwhile, hinge structure is removed controls device, adopts make displays operation processing unit, for controller costly, can effectively reduce electric cost; Simultaneously, without the need to control line between telltale and each IO control unit, near IO control unit, element is electrically connected, the mode adopting communication cable and power lead is electrically connected between telltale and each IO control unit, middle controller needs are supporting compared to existing technology arranges control line, enormously simplify electrical connection master network, greatly reduce the distance that number of electrical lines and electric wire detour, be conducive to diagnosis and the investigation of fault.
During concrete operations, can comprise multiple IO control unit, each IO control unit can be arranged according to the region of control element Relatively centralized, as: as described at least one IO control unit can comprise: an IO control unit; A described IO control unit is arranged in the crane arm of described engineering truck, for at least one in acquisition length information, angle information, wind speed information, height limit information and arm ceiling light information, and the signal of collection is sent to described telltale through described CAN; At least one IO control unit described can also comprise: the 2nd IO control unit; Described 2nd IO control unit be close to described engineering truck main valve arrange (implication be herein close to is, distance between 2nd IO control unit and the main valve of engineering truck is less than predetermined threshold value, this predetermined threshold value is very little, facilitate the installation of the main valve of the 2nd IO control unit and engineering truck) for receiving the solenoid control signal that described telltale sends, and the output of electromagnetic valve in main valve according to described solenoid control signal control; At least one IO control unit described can also comprise: the 3rd IO control unit; Described 3rd IO control unit can be arranged in the electric Relatively centralized position of turntable, for gathering pressure sensor information and/or three circle protection informations; And/or, for the working signal of the working signal and/or buzzer phone that export Warning light.
During concrete operations, described length information, angle information, wind speed information can be analog quantity information, and described height limit information and arm ceiling light information can be switching value information; Preferably, a described IO control unit is used for being sent to described telltale by after described analog quantity information and switching value information framing through described CAN.Certainly, each described IO control unit also can be preferably used for transmitting after the analog signals collected and on-off model framing through described CAN.Sent by the analog signals that will collect and on-off model framing, effectively can reduce number of nodes and the load factor of communication network.
Preferably, described telltale can for carrying the telltale of I/O port, the I/O port of described telltale is for supplementing IO control unit acquisition of signal on described engineering truck or/and the situation of signal output interface quantity not sufficient, and the I/O port of described telltale is connected by CAN with between described IO control unit.By adopting the telltale carrying I/O port, the situation of I/O port quantity not sufficient can be prevented.
