Description
Technical field
The utility model relates to telltale field, particularly a kind of high precision computerized question-and-answer game apparatus.
Background technology
Prior art in question-and-answer game apparatus field adopts RS485 interface to carry out communication mostly, and this bus does not have bus arbitration mechanism, must adopt matching addresses mode, the mode communication of each node of poll, and efficiency is low, and without retransmission mechanism.
In addition, the son of existing question-and-answer game apparatus screen must be used independent current source, and this certainly will bring pressure to field wiring.
Utility model content
The utility model, for prior art above shortcomings, provides a kind of high precision computerized question-and-answer game apparatus, by CAN bus, carries out data transmission, and to adopt bus be the power supply of each question-and-answer game apparatus node, and not only the reliability of data transmission is high, and field wiring is convenient.
The utility model is achieved through the following technical solutions:
A question-and-answer game apparatus, comprising:
Some question-and-answer game apparatus nodes, each question-and-answer game apparatus node comprises: CAN bus interface, power interface, sub-screen interface;
One question-and-answer game apparatus base station, comprise: CAN bus interface, power interface, home screen interface, the CAN bus interface of question-and-answer game apparatus base station connects the CAN bus interface of some question-and-answer game apparatus nodes by CAN bus, the power interface of question-and-answer game apparatus base station connects the power interface of some question-and-answer game apparatus nodes by power lead.
Preferably, the sub-screen interface of some question-and-answer game apparatus nodes connects respectively a sub-screen.
Preferably, the home screen interface of question-and-answer game apparatus base station connects a main screen.
Preferably, question-and-answer game apparatus base station connects a computer equipment by USB.
Preferably, CAN bus and power lead are wrapped in a cable.
Accompanying drawing explanation
Shown in Fig. 1 is structural representation of the present utility model;
Shown in Fig. 2 is CAN bus line connecting structure schematic diagram of the present utility model.
Embodiment
Below with reference to accompanying drawing of the present utility model; technical scheme in the utility model embodiment is carried out to clear, complete description and discussion; obviously; as described herein is only a part of example of the present utility model; it is not whole examples; embodiment based in the utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, belongs to protection domain of the present utility model.
For the ease of the understanding to the utility model embodiment, below in conjunction with accompanying drawing, take specific embodiment and be further explained as example, and each embodiment does not form the restriction to the utility model embodiment.
Please refer to Fig. 1, a kind of high precision computerized question-and-answer game apparatus, comprising: some question-and-answer game apparatus nodes 2, and each question-and-answer game apparatus node comprises: CAN bus interface, power interface, sub-screen interface; One question-and-answer game apparatus base station 1, comprise: CAN bus interface, power interface, home screen interface, the CAN bus interface of question-and-answer game apparatus base station connects the CAN bus interface of some question-and-answer game apparatus nodes by CAN bus, the power interface of question-and-answer game apparatus base station connects the power interface of some question-and-answer game apparatus nodes by power lead.
The sub-screen interface of question-and-answer game apparatus node connects respectively a sub-screen 4, and the home screen interface of question-and-answer game apparatus base station connects a main screen 3, has been used for demonstration effect.The features such as question-and-answer game apparatus node adopts STM32F103 family chip, and it is low that this chip has cost, low in energy consumption, and function is many, but the utility model does not limit at this.
Question-and-answer game apparatus base station connects a computer equipment by USB, adopts HID agreement, has removed from installing driving.Question-and-answer game apparatus base station adopts STM32F107 series, and this family chip USB module and CAN module coexist, and STM32 family chip cost is low, low in energy consumption, powerful, and travelling speed is fast, is well suited for the utility model, but the utility model does not limit at this.
CAN bus and power lead are wrapped in a cable, to facilitate field wiring.(this sentences number of nodes is 5 for example to CAN bus line connecting structure as shown in Figure 2, but the utility model does not limit the quantity of node), CAN bus is existing data transmission technology, generally comprise two data transmission channels, the advantage of using CAN communication bus to bring comprises: bus automatic arbitration, automatic retransmission mechanism (the feature of CAN bus self, automatic arbitration mechanism not only can judge which bar message can take bus at this moment, can also after judgement, guarantee the repellency to other message, i.e. arbitration is won, its transmission process is unblocked, arbitrate unsuccessfully, by the time bus can also be retransmitted after the free time again automatically), effectively guaranteed the reliability of data communication.
In sum, the utility model not only reliability of data communication is high, and is convenient to very much field wiring.
The above; it is only preferably embodiment of the utility model; but protection domain of the present utility model does not limit to therewith; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
