Background technology
At present, the control technology of elevator is except that sub-fraction, computer control and alternating current impression motor driven have roughly all been adopted, so the design of its specification and variability promptly increase relatively, reach in response to different requirement of client (continuing the time of opening the door etc.) owing to on-the-spot floor parameter of each elevator (building number, building height) is different again, so elevator is when plant produced, promptly earlier will set specification reach the standardized program that standard is finished, pre-deposit in the system storage of control board for elevator, treat that elevator finishes to on-site installation, after the details adjustment of each parameter, test run, promptly accuse and finish again.
This kind practice is found in a kind of elevator control device, it mainly is that each parameter (data) that elevator is moved exists in its so-called rewritable read-write memory (RWM) (RAM), so that revise and read-write, comprise the functional parameter of elevator and house condition etc. in the parameter of aforesaid elevator; And at present be factors such as the demand of difference, client in response to its purposes and raising traveling comfort in the employed on the market elevator, and cause the quantity of aforementioned parameters to heighten, be example just, comprised that promptly compartment chauffeur open the door time, floor (take advantage of) chauffeur open the door time, daylight lamp time expand, the shortest acceleration distance, the running of stopping set or the like with elevator implantation parameter; This parameter also has hundreds of with the elevator that the most generally uses at present, so after the workmen installs elevator, for ease of maintenance in the future, these parameters must be copied back one by one, or read with file for future examination with computer.
The work of aforementioned file for future examination is prepared for following elevator faults.Because the elevator device control part is unusual, often be not the unusual of canned data in its memory device (aforesaid parameter), and be mostly by its peripheral cell et out of order, this moment, the user promptly can notify elevator manufacturing company, keeped in repair, and its maintenance step is as follows:
1. the maintainer reaches the spot, and discovery is the unusual of aforementioned control desk, i.e. notification service unit, and inform the model of this elevator, it comprises parameters of hydraulic motor, building height, switch door time etc.;
2. service unit promptly accesses the data of this model control desk, and notice factory makes;
3. factory makes identical control desk of burning, gives service unit;
4. service unit notifies the maintainer that new control desk is taken to the scene to change;
5. do the details parameter adjustment at the scene, let pass then.
Aforementioned flow process needs 2~3 days time approximately, and if this maintenance time is with aforementioned action, and is seemingly quickish, but for the client, but is the maintenance that lacks very much efficient, causes company reputation and product design are had a greatly reduced quality.
In addition, a kind of maintenance mode is also arranged, the flow process that is about to aforementioned the 3rd step remanufacturing control desk changes with similar, compatible main frame substrate and replaces, and after writing each parameter with laptop computer or with the write by hand WriteMode, gives the maintainer to on-the-spot test run, adjustment again; Though this kind practice is rapider, but still can only in 2 days, finish maintenance, can't satisfy client's demand fully.
Again, if the maintainer carries standard host substrate (control desk), but because on one's body the original data of this elevator might not be carried at, so must or hand-writtenly go into mode this elevator internal data is read one by one by computer, check and change in the memory device that writes to new control desk, just can carry out the scene and change operation and details adjustment, therefore, it is oversize that whole maintenance activity work expends man-hour, is the behavior of a low efficiency in fact.
For this reason, the patent No. is 97209711.2 Chinese patent, the control data that discloses a kind of elevator transmits writing station mutually, comprise the main frame substrate, but characteristics be dispose at least on the substrate the master and slave microprocessor of Collaborative Control elevator operation and master and slave access memory, read-only memory (ROM), with another main frame substrate bonded assembly communication interface, control panel and data temporary storage, another memory read, the second two-port random access memory and with its floating point calculator with double-way connection; And the first two-port random access memory of the master and slave microprocessor of difference double-way connection.Thereby the utility model obviously improves the elevator faults maintenance efficiency.During maintenance, the maintainer is the motherboard line of a standard main substrate and et out of order, data in the motherboard memory device of fault changeed one by one write on the standard host plate, two motherboards exchanges got final product again.Though 4-6 minute only consuming time of this handling failure mode can not solve the problem of not stopping ladder in the elevator operation way.
In sum, though most the employing by one of apparatus for controlling elevator overlapped the systems that computer is controlled in the prior art, but when et out of order, all less than guaranteeing that the elevator that is moving can not stop the device of ladder, therefore, in some important place, elevator does not allow to move under the requirement out of service in the way, how to control just and can reach this requirement, become a problem of research.
In view of this, special the utility model that proposes.
The utility model content
