Abstract
The utility model relates to an electronic cam controller, belonging to the technical field of digital components, comprising a dual CPU control module , a display module and a communication interface, wherein a CPU1 and related circuits are used as the control module, which receives the signals of a sensor, sends the relevant data to a displaying part, and outputs the data to an I/O circuit according to the set parameters using relevant computing; a CPU2 is used as the display module to control the display and man-machine interface, receive display data from the control module, and sent the relevant set data of the man-machine interface to the control part through a RS485 interface; only the RS485 interface is used to connect the display module and the control module. The utility model has the advantages that whether the operation of the displaying part is normal, the operation of the control part is not affected, a multi-core distance control cable is not required. The utility model improves the reliability of the system, reduces the costs, and can be widely used in machinery, textiles, printing, aviation and other fields.
Description
Technical field
The present invention relates to a kind of electronic cam controller, electric cam is widely used in fields such as machinery, weaving, printing, aviation, is the key figure parts of industrial equipment, belongs to digitizing component technology field.
Background technology
The principle of work of electronic cam controller is to realize the function of system mechanics cam by sensor and relevant smart circuit (as CPU etc.).Existing electronic cam controller is made of sensor, cpu circuit, I/O circuit, man-machine interface circuit and display circuit.Sensor signal is sent into cpu circuit (if simulating signal need by the digital signal that converts to of signal condition and A/D change-over circuit), CPU is according to the setting of system itself, calculate relevant data and output to the I/O circuit, send video data simultaneously to display circuit, show the indication of relevant information, the man-machine interface circuit mainly is the setting of realization system correlation parameter.During actual the use, sensor is installed on the mechanical main shaft, and sensor output angle signal is given the electric cam circuit, and cpu circuit is set by computing and incorporating parametric and provided output signal, thereby realizes the function of electric cam output.Electric cam has purposes widely, and it can not have wearing and tearing and realizes output at a high speed, can change the angle output combination of cam by parameter setting at any time, can realize the output of angle counting cam, has realized the function that the traditional mechanical cam can't be realized.
The main deficiency that existing electronic cam train exists is, at a part of large industry equipment scene, its demonstration and man-machine conversation are partly on the foreground, and the I/O circuit is placed on the backstage owing to directly connecting various electrical installations, cause main frame and I/O interface stube cable very long like this, along with the increase of I/O interface way, the logarithm of cable significantly increases, cost significantly increases, and has reduced reliability simultaneously.On the other hand, because man-machine interface and display circuit and CPU interrelate, when breaking down, man-machine interface or display circuit may cause CPU work undesired, the lighter system quits work, heavy then cause the I/O output abnormality, visible because the combination of man-machine interface and display circuit and CPU has influenced the reliability of electric cam I/O control output.
Summary of the invention
The objective of the invention is at existing electronic cam train above shortcomings, provide to be beneficial to and reduce cost, help improving a kind of electronic cam controller of electric cam I/O control output reliability.
The objective of the invention is to be achieved through the following technical solutions, a kind of electronic cam controller, comprise and be installed in the mechanical main shaft upper sensor, the CPU that sensor output connects, I/O circuit and display circuit and man-machine interface circuit that CPU output connects, it is characterized in that it is the display module of core that described controller is provided with CPU, connect through communication interface between CPU display module and the CPU that is connected sensor that display circuit is connected with the CPU of display module respectively with the man-machine interface circuit.
Described communication interface can adopt serial communication interface RS485.
The CPU of described connection sensor also connects the auxiliary circuit that comprises power down protection, memory circuit.
The present invention is the improvement to existing electronic cam train circuit structure, control module of being made up of two CPU and display module two large divisions and communication interface constitute, CPU1 and interlock circuit are as control module, it accepts sensor signal, and give the display part with related data, in conjunction with setup parameter, output to the I/O circuit by related operation; CPU2 is as display module, and its task is that control shows and man-machine interface, and it receives the video data from control module, and gives control section with the related data that man-machine interface is set by the RS485 interface; Between display module and control module, only get in touch with by the RS485 interface; The present invention shows that partly whether working properly do not influence control work partly, and this is very important to the commercial unit control procedure.Simultaneously owing to show that part and control part only pass through the RS485 interface and connect, be convenient to piece-rate system, the length that does not need to adopt multicore is apart from umbilical cable, and the present invention has reduced cost again when having improved system reliability, can be widely used in fields such as machinery, weaving, printing, aviation.
Description of drawings
Fig. 1 is a structured flowchart of the present invention.
Embodiment
Further specify the present invention in conjunction with the accompanying drawings and embodiments, as shown in Figure 1, the present invention is made of control module, display module and the communication interface that is connected two modules.Control module by CPU1, connect I/O circuit and the auxiliary circuit that CPU1 is installed in the CPU1 of sensor on the mechanical main shaft and connection and form; Display module is made up of the display circuit and the man-machine interface circuit of CPU2 and connection thereof.Communication interface can adopt serial communication interface, industrial bus or TCP/IP communication, and present embodiment adopts serial communication interface RS485.Control module and display module have working power separately.
CPU1, CPU2 can adopt 8 or 16 single-chip microcomputer 8051 series among the present invention; display circuit and man-machine interface circuit all adopt existing ripe circuit; auxiliary circuit comprises power down protection circuit, memory circuit, and power down protection circuit, memory circuit all adopt existing ripe circuit.
