Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.Be understandable that, specific embodiment described herein is only for explaining the present invention, but not limitation of the invention.It also should be noted that, for convenience of description, illustrate only part related to the present invention in accompanying drawing but not full content.
Embodiment one
Fig. 1 is the diagram of circuit of the method for a kind of elevator controlling local area network bus device id distribution that the embodiment of the present invention one provides, the method can realize the automatic distribution to CAN device id, the system being applicable to be connected by CAN performs, this system comprise trunking, from equipment, elevator master board and PC end (PC end) as upper computer etc.
As shown in Figure 1, the method comprises:
S110, read elevator job number from equipment by elevator master board, and store;
In CAN, have a trunking, all the other are from equipment.From equipment and the selected equipment carrying out communicating, in elevator monitoring, there is multiple stage from equipment.Every platform is all connected with an elevator master board from equipment, when after device power, will read elevator job number by elevator master board, and is stored in corresponding to equipment, and wherein elevator job number is unique.Further, before reading elevator job number from equipment by elevator master board, also comprise: described from device power time, if unallocated effective ID detected, then local ident is set to the interim ID given tacit consent to.Wherein, interim ID can be set to arbitrary value, preferably, arranges 0 for the interim ID from equipment self.
S120, describedly send CAN ID request for data bag to upper computer from equipment through trunking, described ID request for data handbag draws together interim ID and elevator job number;
Trunking is for can, for the equipment connected in CAN, replace obtaining No. ID from equipment to upper computer application.
Upper computer is the computing machine that directly can send manipulation order, is generally PC (PersonalComputer, PC), can shows various signal (hydraulic pressure, water level, temperature etc.) on its screen.
Exemplary, as shown in Figure 2, in CAN communication bus 201, one end is connected to computing machine (PC) the i.e. upper computer 203 that directly can send manipulation order, the other end connects multiple stage from equipment 204, and be respectively connected in parallel between equipment 204, every platform is connected with the elevator master board 205 in an elevator 206 separately from equipment 204, to connect with between equipment 204 trunking 202 at upper computer 203, can retransmit signal transmission with the signal transmission amplified in communication.Respectively can make respectively to be independent of each other from the work between equipment from being connected in parallel between equipment.
S130, upper computer based on the described ID request for data bag received, for described from the effective ID of facility assignment;
Effective ID that upper computer distributes can perform based on setting rule, and preferably, upper computer, based on the described ID request for data bag received, comprises from the effective ID of facility assignment for described:
Upper computer, based on the described ID request for data bag received, according to the effective ID distributed, is described from the effective ID of facility assignment according to set algorithm.
Described set algorithm can have multiple, and preferably, the order ascending according to natural number is distributed successively, such as, upper computer, based on the described ID request for data bag received, the effective ID distributed adds up 1, as new effective ID, distribute to described from equipment.
Can be 1 ~ n (n is natural number) from effective ID of equipment, preferably, upper computer will distribute ID after receiving ID request for data bag from 1, and send ID distribute data bag to from equipment.
Exemplary, in elevator controlling local area network bus equipment, there is multiple stage from equipment, suppose there are 5, after device power, there are 3 from equipment effective ID (being respectively 1 ﹑ 2 ﹑ 3), 2 are had effective ID not detected from equipment, then these two will send ID request for data bag by trunking to upper computer from equipment A ﹑ B, supposing that upper computer first receives distributes to from device A using 4 as effective ID from the ID request for data bag of device A is then automatic, then distributes to 5 from equipment B as effective ID.If also have more how unallocated effective ID from equipment, then upper computer will distribute it successively.
ID distribute data bag is sent to from equipment by trunking by S140, described upper computer, and described ID distribute data bag comprises effective ID, interim ID and elevator job number;
Further, ID distribute data bag to be sent to by trunking and to comprise from equipment by described upper computer:
Described ID distribute data bag is sent to trunking by described upper computer;
Described ID distribute data bag sends to from equipment by described trunking.
ID distribute data bag is first sent to the trunking be directly connected with it by upper computer, and ID distribute data bag is sent to from equipment after receiving described ID distribute data bag by trunking.
S150, described from equipment according to the described ID distribute data bag received, carry out effective ID and automatically configure.
Concrete, described from equipment according to the described ID distribute data bag received, carry out effective ID and automatically configure and comprise:
The described described ID distribute data bag received from equipment, obtains effective ID and elevator job number;
Describedly from equipment, the elevator job number got to be mated with the elevator job number of storage, carry out effective ID when mating consistent and automatically configure.
The method that the elevator controlling local area network bus device id that the embodiment of the present invention provides distributes, is from equipment application ID by trunking, can is from the effective ID of facility assignment automatically, applies more convenient.
Embodiment two
The data exchange process schematic diagram of the method that a kind of elevator controlling local area network bus device id that Fig. 3 provides for the embodiment of the present invention two distributes.In the whole process that elevator controlling local area network bus device id distributes, after powering on, first from equipment by elevator master board read elevator job number and preserve, do not detect that effective ID's will send ID request for data bag to trunking from equipment afterwards, this ID request for data bag is passed to PC end by trunking again, after PC termination receives ID request for data bag, by the allocative efficiency ID respectively of the sequencing according to reception, and ID distribute data bag is transferred to again corresponding from equipment by trunking, receive after ID distribute data bag from equipment and mate with the elevator job number information data packet, if consistent, ID is revised as effective ID, so far be allocated successfully from the ID of equipment.Each from equipment all by the automatic allocative efficiency ID of above-mentioned data transmission procedure.
The data exchange process of the method that the elevator controlling local area network bus device id provided by the embodiment of the present invention is distributed, can be from the automatic allocative efficiency ID of equipment, apply more convenient.
Note, above are only preferred embodiment of the present invention and institute's application technology principle.Skilled person in the art will appreciate that and the invention is not restricted to specific embodiment described here, various obvious change can be carried out for a person skilled in the art, readjust and substitute and can not protection scope of the present invention be departed from.Therefore, although be described in further detail invention has been by above embodiment, the present invention is not limited only to above embodiment, when not departing from the present invention's design, can also comprise other Equivalent embodiments more, and scope of the present invention is determined by appended right.
