Abstract
A triggering type low-power CAN bus apparatus comprises a switchboard CPU, a CAN on-site bus and several CAN communication nodes. Each CAN communication node comprises a bus driver connected with the CAN on-site bus, a node CPU, a reception unit, a reception filtering unit, a sleep wake up unit and a transmission unit. A memory is arranged in each reception unit, and the memories store the information received by the CAN communication nodes from the CAN on-site bus. The triggering type low-power CAN bus apparatus effectively reduces power consumption.
Description
Technical field
The utility model relates to the communications field, espespecially a kind of low-power consumption CAN bus unit of trigger-type.
Background technology
, all there are many problems in the dcs that the conventional RS-485 of use builds based on R line,, data low such as total line use ratio transmit probability low, without fault tolerant mechanism etc.
Utility model content
The purpose of this utility model is to provide a kind of low-power consumption CAN bus unit of trigger-type that can real-time dynamic monitoring electric terminal multiplexing electric abnormality.
For this reason, the utility model provides a kind of low-power consumption CAN bus unit of trigger-type, comprise the CAN communication node on exchange CPU, CAN fieldbus and the some CAN of being connected in fieldbus, each CAN communication node includes bus driver, node cpu, receiving element, receiving filtration unit, sleep awakening unit and the transmitting element being connected on CAN fieldbus, in described receiving element, be provided with storer, the information that described memory stores CAN communication node receives from CAN fieldbus.
In described receiving element, the information of storage comprises the information mark literary composition symbol that is useful on judgement.
The Information Access of the low-power consumption CAN bus unit of described trigger-type has utilized the access working method of broadcast type, information is at any time delivered on idle CAN fieldbus by any node, and each CAN communication node must receive all information that occur in bus.
With respect to prior art, the low-power consumption CAN bus unit of the utility model trigger-type arranges storer and stores the information receiving from CAN fieldbus in the receiving element of each CAN communication node, and the described information of foundation is determined the mode of operation of each CAN communication node, each CAN communication node is not being needed in situation in sleep state, greatly reduce power consumption, saved the energy.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the low-power consumption CAN bus unit of the utility model trigger-type.
Embodiment
Refer to shown in Fig. 1, the low-power consumption CAN bus unit of the utility model trigger-type comprises the CAN communication node on exchange CPU, CAN fieldbus and the some CAN of being connected in fieldbus.
Each CAN communication node includes bus driver, node cpu, receiving element, receiving filtration unit, sleep awakening unit and the transmitting element that connects CAN fieldbus.In described receiving element, be provided with storer for storing the information receiving from CAN fieldbus.
The low-power consumption CAN bus unit of the utility model trigger-type is the serial communication network of the distributed control of a kind of effective support, and it is worked in semiduplex mode.A CAN communication node sends information, and a plurality of CAN communication nodes receive information, have realized full distributed multi-computer system.The Information Access of the low-power consumption CAN bus unit of described trigger-type has utilized the access working method of broadcast type, information can be at any time delivered on idle CAN fieldbus by any node, each CAN communication node must receive in all information occurring in bus the storer that described information is stored in to receiving element, then according to the information mark literary composition symbol receiving, whether determine reading information, when information mark literary composition symbol requires to read processing relevant information, node cpu will wake CAN communication node up, otherwise, under the mode of operation of CAN communication node in sleep, so, node cpu can automatic frequency adjustment be controlled the mode of operation of each CAN communication node, to reach reduction power consumption, save energy object.
Compared to prior art, the low-power consumption CAN bus unit of trigger-type of the present utility model arranges storer and stores the information receiving from CAN fieldbus in the receiving element of each CAN communication node, and the described information of foundation is determined the mode of operation of each CAN communication node, each CAN communication node is not being needed in situation in sleep state, greatly reduce power consumption, saved the energy.
Claims (1)
1. the low-power consumption CAN bus unit of a trigger-type, it is characterized in that: comprise the CAN communication node on exchange CPU, CAN fieldbus and the some CAN of being connected in fieldbus, each CAN communication node includes bus driver, node cpu, receiving element, receiving filtration unit, sleep awakening unit and the transmitting element being connected on CAN fieldbus, in described receiving element, be provided with storer, the information that described memory stores CAN communication node receives from CAN fieldbus.
