Abstract
The utility model relates to an operation recorder for a cam controller. The operation recorder for the cam controller is a device for automatically recording instructions transmitted by the cam controller, and comprises a memorizer, a singlechip and an on-off input interface circuit, wherein the memorizer is used for memorizing operation recording data; the input end of the on-off input interface circuit is connected with a signal wire for being correspondingly connected with a contact of the cam controller; the output end of the on-off input interface circuit is connected with the singlechip; and the singlechip is connected with the memorizer, can record the instructions transmitted by the cam controller in real time, and can record the instructions for a long time for administrative staff to inquire.
Description
Technical field
The utility model relates to a kind of operation recorder, particularly crane cam controller operation recorder for record cam controller operational order.
Background technology
Cam controller is called contactor formula controller again, is a kind of large-scale control apparatus, also is many gears, multiconductor, utilizes manual operation, and rotating cam goes to connect and the contact switch of disjunction by big electric current.Cam controller is mainly used in the startup of the middle-size and small-size wound-rotor asynchronous motor of control in the hoisting device, stops speed governing, commutation and braking.The violation operation behavior often appears in crane in use operating personnel, causes crane generation security incident, and accident the back takes place because there not being operating personnel's operation note, causes judging accidents caused reason in time, accurately.So the operational order that the crane operation personnel are sent carries out record, the safe operation of crane is had great importance.
The utility model content
The purpose of this utility model provides a kind of cam controller operation recorder, in order to solve the equipment that now the cam controller operational order is not recorded, can't provide the problem of researching and analysing material after accident takes place.
For achieving the above object, scheme of the present utility model is: the cam controller operation recorder comprises storer, single-chip microcomputer and switch value input interface circuit for the storage operation record data; The input end of switch value input interface circuit connects and is used for the corresponding signal wire that connects the cam controller contact, and the output terminal of switch value input interface circuit connects single-chip microcomputer, and single-chip microcomputer connects described storer.
Described single-chip microcomputer also is connected with for the data export interface circuit of deriving record data.
Described single-chip microcomputer also is connected with the display for the display operation record data.
Described switch value input interface circuit is the auxiliary reclay circuit.
Described data export interface circuit is usb circuit or communication interface circuit.
Described cam controller operation recorder is crane cam controller operation recorder.
Because signal wire connects the corresponding contacts of cam controller, so can note operate (being the operational order that each cam controller sends) at every turn.Cam controller operation recorder of the present utility model is cam controller " black box ", can be after accident take place, and the playback operation process is analyzed, decision operation is very wrong, and is significant to accurate judgement accident occurrence cause; In operate as normal, the safety manager is passed judgment on operating personnel's professional skill by the analytic record data, be the foundation whether safety manager's decision operation personnel operate against regulations.
The utility model is collected and record service data by single-chip microcomputer and storer, forms record data, by the data export interface record data is exported to other storage mediums, as USB flash disk; The data export interface also can be communication interface, so that directly to other computing machines or network transmission record data.
The utility model not only can be preserved record data for a long time, can also data directly be shown in modes such as literal or figures by display, so that directly check.
Description of drawings
Fig. 1 is cam controller and cam controller operation recorder connection diagram;
Fig. 2 is cam controller operation recorder structured flowchart.
Embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.
Cam controller operation recorder 4 as shown in Figure 1 comprises storer, single-chip microcomputer and switch value input interface circuit for the storage operation record data; The input end of switch value input interface circuit connects and is used for the corresponding signal wire 3 that connects cam controller 1 contact 2, and the output terminal of switch value input interface circuit connects single-chip microcomputer, and single-chip microcomputer connects described storer.
Such scheme can be realized basic function of the present utility model, is the more perfect embodiment of a kind of function as Fig. 2.The cam controller operation recorder is crane cam controller operation recorder.Single-chip microcomputer is connected with for the data export interface circuit of deriving record data, is used for the display of display operation record data.
The switch value input interface circuit can adopt the auxiliary reclay circuit, also can adopt input interface circuit, as level shifting circuit etc., can also adopt buffer circuits such as optocoupler.Data export interface circuit is usb circuit or communication interface circuit.
When operating personnel's operation of cam controller control crane, the rotation meeting trigger relay of cam, the signal wire that connects on the relay can be transferred to contact switch amount signal crane cam controller operation recorder, this signal is handled through the reduction of switch value input interface circuit, be transferred to single-chip microcomputer, after single-chip microcomputer is handled data are stored into storage chip, when needs call data, single-chip microcomputer is transferred data from storage chip, and be presented at the register display window, also can data be copied out by the network transmission or by USB flash disk, check in detail on computers and data analysis.
Claims (6)
1. the cam controller operation recorder is characterized in that, comprises storer, single-chip microcomputer and switch value input interface circuit for the storage operation record data; The input end of switch value input interface circuit connects and is used for the corresponding signal wire that connects the cam controller contact, and the output terminal of switch value input interface circuit connects single-chip microcomputer, and single-chip microcomputer connects described storer.
