The invention discloses a ZigBee-CAN based information issue terminal. The terminal comprises a determination unit used for determining whether user terminals accessing a network are specific user terminals needing data reception or not; a quantity estimation sub-unit used for estimating the quantity of the user terminals in the network; a transmitting unit used for receiving data information transmitted by a temperature sensor and transmitting data signals to a CAN bus controller; a CAN bus control unit used for receiving CAN network transmission instruction data signals and transmitting monitoring data through a CAN bus protocol; a ZigBee transmitting-receiving unit used for receiving ZigBee network monitoring data and transmitting instruction data to the specific user terminals. The terminal realizes communication connection between a wired network and a wireless network and is advantaged by security, low price, high reliability, easy expansion, and the like.
Description
Technical field
The present invention relates to networking technology area, particularly a kind of information release terminal based on ZigBee-CAN.
Background technology
Along with the development of wireless communication technology, Wireless Telecom Equipment is constantly ripe, and cost also further reduces, however, wiring difficulty higher area comparatively severe at operational environment, and the cost that provides spider lines is higher; Wireless-transmission network can address this problem, but the transmission range of wireless-transmission network, and transmission quality is restricted.
Inventor finds in the process of research, and CAN bus is as a kind of field bus technique of maturation, the feature such as have that reliability is high, real-time good and cost is low; ZigBee wireless communication technique, has low cost, low-power consumption, low rate and in unlicensed band work, can be widely used in the fields such as Industry Control, environment control, business control and home automation.Therefore, by CAN bus and the combination of ZigBee wireless communication technique, CAN bus has very high reliability and cost performance as industrial field bus system, how the two is combined with, and is the difficult problem that the present invention studies.
Summary of the invention
The invention provides a kind of information release terminal based on ZigBee-CAN, realized CAN bus and the combination of ZigBee wireless communication technique, met the use of technical grade family.
For achieving the above object, the embodiment of the present invention provides a kind of information release terminal based on ZigBee-CAN, comprising:
Judging unit, for judging whether the user terminal of access network is the specific user terminal that need to receive data;
Quantity survey subelement, for the quantity of estimation network user terminal;
Transmitting element, for receiving the data message of described temperature sensor transmission, sends data-signal to CAN bus control unit;
CAN bus control unit, for receiving CAN Internet Transmission director data signal and sending Monitoring Data by CAN bus protocol;
ZigBee Transmit-Receive Unit, for receiving ZigBee-network Monitoring Data and sending director data, sends described data to described specific user terminal.
Described quantity survey subelement comprises:
The first quantity survey subelement, for according to the equipment room channel confliction occurring in the unit interval number or the unit interval in the association request that receives number or the unit interval in the request of data that receives number, the quantity of user terminal in estimation network.
This terminal also comprises:
Identify unit, for to needing the data that user terminal reads to identify, and notifies whether the user terminal that described judging unit judges access network is the specific user terminal that need to receive data.
Terminal provided by the invention can realize data retransmission, processing and the calculating between ZigBee-network and CAN bus; The features such as equipment operation is low in energy consumption, and the software and hardware system of equipment all adopts low power design technique, has reduced energy consumption, and equipment can work long hours, and has high reliability, strong data-handling capacity.
Accompanying drawing explanation
Fig. 1 is a kind of information release terminal structural representation based on ZigBee-CAN in the embodiment of the present invention.
Embodiment
Below the embodiment of the embodiment of the present invention is described in detail:
As shown in Figure 1, be the structural representation of the embodiment of the present invention, mainly comprise following part:
Judging unit, for judging whether the user terminal of access network is the specific user terminal that need to receive data;
Quantity survey subelement, for the quantity of estimation network user terminal;
Transmitting element, for receiving the data message of described temperature sensor transmission, sends data-signal to CAN bus control unit;
CAN bus control unit, for receiving CAN Internet Transmission director data signal and sending Monitoring Data by CAN bus protocol;
ZigBee Transmit-Receive Unit, for receiving ZigBee-network Monitoring Data and sending director data, sends described data to described specific user terminal.
Described quantity survey subelement comprises:
The first quantity survey subelement, for according to the equipment room channel confliction occurring in the unit interval number or the unit interval in the association request that receives number or the unit interval in the request of data that receives number, the quantity of user terminal in estimation network.
This terminal also comprises:
Identify unit, for to needing the data that user terminal reads to identify, and notifies whether the user terminal that described judging unit judges access network is the specific user terminal that need to receive data.
Terminal provided by the invention can realize data retransmission, processing and the calculating between ZigBee-network and CAN bus; The features such as equipment operation is low in energy consumption, and the software and hardware system of equipment all adopts low power design technique, has reduced energy consumption, and equipment can work long hours, and has high reliability, strong data-handling capacity.
Information release terminal adopts the mode of the information of regularly publishing to carry out information pushing.Concrete, information release terminal adopts the mode of regular transmission information to carry out information pushing, can broadcast to all user terminals, also can carry out multicast for the user terminal that sends request of data.In the time interval of information pushing, can be to be set by user terminal, also can dynamically determine by information release terminal.
Whether the embodiment of the application of the invention, provides information transmission system and equipment based on ZigBee-network and CAN bus, before data are sent to specific user terminal, be that the user terminal that need to receive data judges in advance to user terminal.This implementation method can be applied to, under pattern that beacon enables to enable with non-beacon, to the message that need to push to user terminal, control, and have advantages of network lay convenient, cost is low.
Through the above description of the embodiments, those skilled in the art can be well understood to the mode that the present invention can add essential general hardware platform by software and realize, and can certainly pass through hardware, but in a lot of situation, the former is better execution mode.Understanding based on such, the part that technical scheme of the present invention contributes to prior art in essence in other words can embody with the form of software product, this computer software product is stored in a storage medium, comprise that some instructions are with so that a computer equipment (can be personal computer, server, or the network equipment etc.) carry out the method described in each embodiment of the present invention.
Disclosed is above only several specific embodiment of the present invention, and still, the present invention is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
