Description
The technical field is as follows:
the utility model relates to a BMS system based on wireless mesh communication, it belongs to the electric communication technology.
Background art:
with the development of intellectualization and the maturation of wireless mesh technology in automobiles, it is becoming a necessary trend that wireless communication replaces the traditional wired connection between a battery pack and a battery management system. The BMS system based on wireless grid communication solves the reliability problem caused by the automobile wiring harness and existing for a long time, simplifies the design and manufacture of the BMS, and ensures that the system is safer, more intelligent, more environment-friendly and cheaper.
Because the traditional BMS adopts wired connection, the number and the positions of the slave machines need to be planned at the initial stage of BMS system design, the design and manufacture difficulty is high, and the expansion capability of the system is not strong.
The utility model has the following contents:
the utility model relates to a solve the problem that above-mentioned prior art exists and provide a BMS system based on wireless grid communication, it adopts the wireless grid mode, reducible pencil cost and connector cost, and it is more nimble to follow the position determination of machine.
The utility model discloses the technical scheme who adopts has: a BMS system based on wireless grid communication is composed of a slave machine and a host machine, wherein the slave machine and the host machine are provided with a plurality of redundant communication paths, the slave machine is composed of an AFE multi-battery front-end acquisition chip and a ZIGBEE wireless module, and the AFE multi-battery front-end acquisition chip is connected with the ZIGBEE wireless module through an SPI.
Furthermore, the ZIGBEE wireless module also has a routing function.
The utility model discloses following beneficial effect has:
1. the system has strong expansion capability, and because a wireless grid mode is adopted, networking is easy, the position of a wireless slave is more flexibly placed, and the number of sensors for temperature, voltage, current and the like can be easily increased according to application requirements.
2. The security improves, and the CAN or isoSPI bus is adopted to traditional BMS system mostly, utilizes the daisy chain mode to establish ties the battery monitor chip, and in case a certain department connects the problem, whole system all will be paralysed, and adopts wireless system need not to consider the system failure problem that communication harness caused.
3. The wire harness cost and the connector cost are reduced, and the light weight trend of the automobile is met while the cost is saved.
4. The demand to the low pressure power supply has been cancelled, and traditional BMS needs extra power to provide data acquisition, bus communication, and system power supplies such as peripheral sensor adopt wireless communication's BMS can directly get the electricity from the battery of monitoring, through low-power consumption management, can cancel the external power supply demand.
Description of the drawings:
fig. 1 is a frame diagram of the wireless mesh communication based BMS system of the present invention.
Fig. 2 is a structural diagram of a slave in the BMS system based on wireless mesh communication according to the present invention.
The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings.
The utility model discloses BMS system based on wireless mesh communication comprises from machine and host computer, follows the machine and possess a plurality of redundant communication path with the host computer, follows the machine and gathers chip and ZIGBEE wireless module by the many battery front ends of AFE and constitute, and many battery front ends of AFE gather the chip and pass through SPI and be connected with ZIGBEE wireless module. The AFE multi-battery front-end acquisition chip realizes battery cell voltage detection, temperature detection and balance management, and through SPI and ZIGBEE wireless module communication, ZIGBEE wireless module information is transferred and is deposited and send to the host computer, and ZIGBEE wireless module still possesses the routing function, can buffer memory other systems of module nearby, guarantees the redundancy of mesh network signal link.
The utility model discloses BMS system based on wireless grid communication adopts wireless grid structure, utilizes ripe ZIGBEE wireless network protocol to realize, and entire system takes the network self-healing function, follows the machine and possesses the communication path who possesses a plurality of redundancies with the host computer, the optimal path of automatic selection and host computer communication. The method improves the connection quality and coverage range and ensures the reliability of communication.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
