Description
Technical field
This utility model relates to a kind of fork truck, especially relates to a kind of electri forklift.
Background technology
Existing electri forklift generally comprises host computer, driver, instrumental panel and valve control and battery, driver has traveling driver and pump driver, host computer passes through serial ports and travels driver or be connected with pump driver, instrumental panel, travel and connected by CAN between driver and pump driver, instrumental panel, traveling driver and pump driver are connected with valve control by I/O mouth respectively, and battery powers to traveling driver, pump driver, instrumental panel and valve control.The battery that existing domestic electri forklift is used is lead-acid accumulator, but lead-acid accumulator itself to there is pollution, charging process in the fabrication process slow, and owing to its energy density is little, the feature that electri forklift is intended for single use time length, load-carrying is big therefore cannot be met.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of charging interval is short, single charge uses time length and the electri forklift of powerful.
nullThe technical scheme that the above-mentioned technical problem of this utility model solution is used is: a kind of electri forklift，Including driver、Instrumental panel and valve control and battery module，Described driver is sailed driver by left lateral、Right travel driver and pump driver composition，Described left lateral sails driver、Described right travel driver、It is provided with CAN communication interface in described pump driver and described instrumental panel，It is characterized in that: on described valve control, be provided with CAN communication interface，Described battery module is by lithium battery and the battery management system (BMS that is connected and has CAN communication interface with described lithium battery，BATTERY MANAGEMENT SYSTEM) composition，Described lithium battery is respectively described left lateral and sails driver、Described right travel driver、Described pump driver、Described instrumental panel and described valve control are powered，Described left lateral sails driver、Described right travel driver、Described pump driver、Described instrumental panel、Described valve control and described battery management system are all as CAN node，Each described CAN node is connected in the CAN of car load by the CAN communication interface of self.
Each described CAN node is assigned unique node address.This CAN node is identified by a unique node address of each CAN node distribution.
All described CAN nodes are provided with same communication protocol.
Described communication protocol is CANOPEN agreement.After installation CANOPEN agreement, communication management is by NMT(management message) data transmission, real time data passes through PDO(process data object) data transmission, and parameter is arranged by SDO(Service Data Object) data transmission, baud rate is 250K.
Compared with prior art, the utility model has the advantage of: left lateral is sailed driver, right travel driver, pump driver, instrumental panel, valve control and battery management system are all as CAN node, and make each CAN node be articulated in the CAN of car load by the CAN communication interface of self, so battery management system of lithium battery can pass through PDO(process data object) data send lithium battery information, electricity including lithium battery, voltage and fault message, thus reach farthest to protect the safety problem of lithium battery and electri forklift by the data interaction of car load and the battery management system of lithium battery, substantially prolongs the service life of lithium battery；And owing to employing lithium battery, therefore the charging interval is short, single charge uses time length and powerful.
Accompanying drawing explanation
Fig. 1 is composition and the connection diagram of electri forklift of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
nullA kind of electri forklift that the utility model proposes，As shown in Figure 1，It includes driver、Instrumental panel 2 and valve control 3 and battery module，Driver is sailed driver 11 by left lateral、Right travel driver 12 and pump driver 13 form，Left lateral sails driver 11、Right travel driver 12、It is provided with CAN communication interface in pump driver 13 and instrumental panel 2，CAN communication interface it is provided with on valve control 3，Battery module is by lithium battery 41 and the battery management system 42(BMS that is connected and has CAN communication interface with lithium battery 41，BATTERY MANAGEMENT SYSTEM) composition，Lithium battery 41 respectively left lateral sails driver 11、Right travel driver 12、Pump driver 13、Instrumental panel 2 and valve control 3 are powered，Left lateral sails driver 11、Right travel driver 12、Pump driver 13、Instrumental panel 2、Valve control 3 and battery management system 42 are all as CAN node，Each CAN node is connected in the CAN of car load by the CAN communication interface of self.
In this particular embodiment, each CAN node is assigned unique node address, this CAN node is identified by a unique node address of each CAN node distribution, the node address of each CAN node can be set by manufacturer, as the node address of battery management system 42 is set as 0x01；All CAN nodes are provided with same communication protocol, communication protocol is existing CANOPEN agreement, after CANOPEN agreement is installed, communication management manages message by NMT() data transmission, real time data passes through PDO(process data object) data transmission, parameter is arranged by SDO(Service Data Object) data transmission, baud rate is 250K.
In this particular embodiment, left lateral is sailed driver 11, right travel driver 12, pump driver 13, instrumental panel 2, valve control 3, lithium battery 41 and battery management system 42 and is all used prior art.
Owing to lithium battery 41 uses non-aqueous electrolytic solution, therefore without checking and adding electrolyte, once encapsulate, life-time service, becomes real maintenance-free battery, more environmentally-friendly, pollution-free, corrosion-free, unleaded, and use the safest, even if service life is to reclaiming, environmentally safe, the charging interval is short, 1～3 hours i.e. chargeable the most complete, can charge to electri forklift lunch break when.Owing to lithium battery 41 has energy density height, the use time using the electri forklift single charge of lithium battery 41 therefore can be made long, and powerful.
Left lateral is sailed driver 11 by this electri forklift, right travel driver 12, pump driver 13, instrumental panel 2, valve control 3 and battery management system 42 are all as CAN node, and make each CAN node be articulated in the CAN of car load by the CAN communication interface of self, so battery management system 42 of lithium battery 41 can pass through PDO(process data object) data send lithium battery 41 information (include the electricity of lithium battery 41, voltage and fault message), after car load receives the fault message of lithium battery 41, can keep in repair and failure code is shown on instrumental panel 2 by parking waiting；When car load receives the electricity of lithium battery 41 less than 20%, can forbid that driver's goods that hoists, to protect lithium battery 41, can send alert notification driver simultaneously and go charging on instrumental panel 2；When the battery management system 42 of lithium battery 41 receives the PDO(process data object of car load) data time, be made whether to need the judgement of powered down sleep to reach the effect of economize on electricity.
This electri forklift reaches farthest to protect the safety problem of lithium battery 41 and electri forklift by the data interaction of the battery management system 42 of car load and lithium battery 41, substantially prolongs the service life of lithium battery 41.
