Abstract
A CAN bus device tester comprises a single chip microcomputer controller 1, a converter 2, a keyboard 4, a liquid crystal display 5 and a USB bridge 3, wherein a signal output end and a signal input end of the single chip microcomputer controller 1 are connected with a signal input end and a signal output end of the converter 2, an operation signal input end of the single chip microcomputer controller 1 is connected with the keyboard 4, a display signal input end of the single chip microcomputer controller 1 is connected with an input end of the liquid crystal display 5, and the single chip microcomputer controller 1 is equipped with the USB bridge 3. The CAN bus device tester can give instructions to subsurface equipment and withdraw data through the converter 2, treats the data in the single chip microcomputer controller 1, and displays through the liquid crystal display 5, or sends the data into a computer for displaying and processing through the USB bridge 3, meets requirements of device detection and failure location, has the function of testing logging equipment of CAN bus form, and provides an analysis tool for bus test.
Description
Technical field
The utility model relates to a kind of oil well logging instrument, particularly a kind of CAN bus apparatus tester.
Background technology
The bus-structured oil well logging instrument of CAN is widely used in the logging point in each oil field.In the well logging manufacturing process,, before carrying out logging operation, should detect because logger may be damaged in transportation and operating process.Yet at present be not equipped with testing equipment in the logger that uses, and instrument detected, not only inconvenience but also very expensive with a whole set of communication system.Therefore need a kind of CAN bus apparatus tester, whether testing equipment can operate as normal or be used for fault location when equipment is needed repairing before logging system work.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the purpose of this utility model is to provide a kind of CAN bus apparatus tester, has test function to the logging equipment of CAN bus form, can realize showing to downhole instrument transmitting order to lower levels and unrecoverable data and with liquid crystal display, perhaps as required data being sent into computer by USB interface shows and handles, the needs of Equipment Inspection and fault location have been satisfied, for bus test provides analysis tool.
In order to overcome the defective of above-mentioned technology, the technical solution of the utility model is achieved in that a kind of CAN bus apparatus tester, comprise singlechip controller 1, the signal output, the input that comprise singlechip controller 1 link to each other with signal input, the output of converter 2, the operation signal input of singlechip controller 1 links to each other with keyboard 4, and the demonstration signal output part of singlechip controller 1 links to each other with the input of LCD 5.
Described singlechip controller 1 also is provided with USB bridger 3.
The utility model compact conformation, be convenient to on-the-spot the use, and can realize downhole instrument transmitting order to lower levels and unrecoverable data are shown with liquid crystal display, perhaps as required data being sent into computer by USB interface shows and handles, the needs of Equipment Inspection and fault location have been satisfied, for bus test provides analysis tool.
Description of drawings
Accompanying drawing is a structure principle chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operating principle are described in detail.
With reference to accompanying drawing, a kind of CAN bus apparatus tester, comprise singlechip controller 1, the signal output part P0.1 mouth of singlechip controller 1 switches through the signal input part RXD pin of parallel operation 2, the signal input part P0.2 mouth of the signal output part TXD pin order sheet machine controller 1 of converter 2; The operation signal input of singlechip controller 1 links to each other with keyboard 4, and promptly 8 of keyboard 4 alignments are connected on respectively on the P2 mouth of singlechip controller 1, and 8 lines are connected on respectively on the P3 mouth of singlechip controller 1; The demonstration signal output part of singlechip controller 1 links to each other with the input of LCD 5, the WR that is LCD 5 terminates on the P1.3 mouth of singlechip controller 1, RD terminates on the P1.4 mouth, CS terminates on the P1.5 mouth, A0 terminates on the P1.6 mouth, RES terminates on the P1.7 mouth, and data terminal DB0-DB7 is connected on respectively on the singlechip controller 1P4.0-P4.7.
Described singlechip controller 1 also is provided with USB bridger 3, and promptly the output P0.6 mouth of singlechip controller 1 connects the RXD pin of USB bridger 3, the input P0.7 mouth of the TXD pin order sheet machine controller 1 of USB bridger 3.
Operating principle of the present utility model is: singlechip controller 1 as kernel control chip to the downhole instrument transmitting order to lower levels and receive downhole instrument and transmit the data of returning; Converter 2 is sent into the order of singlechip controller 1 in the downhole instrument, and downhole instrument CAN bus response data is converted to serial data sends into singlechip controller 1 and handle; Keyboard 4 is selected according to program setting or corresponding order of input and needs data presented, and data and order are presented on the LCD 5; USB bridger 3 converts the serial data of singlechip controller 1 to the usb data form, sends into host computer and handles.
