Abstract

The utility model discloses a single bus online programming device, which comprises an oil field well, a DSP control panel and online debugging equipment, wherein the DSP control panel is arranged below the oil field well; the online debugging equipment is arranged outside the oilfield well; and the online debugging equipment is in communication connection with the DSP control board through the LIN bus. Because the underground space is limited, the wire core which can be led out is very limited, the single-bus online programming device adopts an LIN protocol communication mode, communication connection is established between a DSP control board and online debugging equipment through an LIN bus, the LIN bus is low in cost and wide in application range, and data transmission and verification work is completed by sending a command to the underground DSP control board through the online debugging equipment, so that the DSP chip in the DSP control board is programmed online.

Description

Single-bus online programming device

Technical Field

The utility model relates to an oil field DSP controller technical field in pit specifically is a device is write to online fever of monobus.

Background

In order to ensure the operation reliability of the oil field underground equipment, after the software design of the underground DSP controller is completed, the software needs to be burnt into a circuit board to carry out various simulation experiments for verification and testing. In the actual testing stage of the downhole equipment, the DSP controller needs to be installed in special sealing equipment such as a sleeve and then is put into an oil well. If the program goes wrong in the DSP controller, the uncontrollable DSP controller can only be fished out of the oil well, the sealing equipment is opened again to burn, and the process is excessively complicated and consumes manpower and financial resources relatively. The most common programming method at present comprises two methods, one is downloading through a special programming device, the method is programming in a pluggable form such as dual-in-line, and the like, frequent plugging and unplugging are needed during later modification, the wear to the programming device is large, and the service life is shortened; and secondly, a patch type FLASH or E2PROM memory is used for storing program codes, the method can reduce the size space of a PCB (printed Circuit Board) occupied by components on one hand, and can lead a downloading interface out to the periphery of equipment on the other hand, the equipment does not need to be disassembled and assembled again, related experiments do not need to be carried out again, the abrasion on mechanical parts is avoided, the configuration of human resources and debugging equipment is relieved, and the time for research, development and test is saved. Underground equipment needs to be connected with ground equipment in an armored cable mode, the specification of the armored cable is limited, the number of the wire cores inside the armored cable and the cross section of the wire cores become important consideration factors, and a unibus online programming device is urgently needed for better utilizing the wire cores inside the armored cable.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a device is burnt write on line to monobus for improve the convenience of DSP controller procedure change in the pit, thereby promote the security and the reliability of downhole equipment, solved the oil field downhole equipment procedure and burnt write loaded down with trivial details problem, and save the sinle silk and support the long distance and burn write on line, can realize long-term reliable download work.

In order to achieve the above object, the utility model provides a following technical scheme: a single-bus online programming device comprises an oil field well, a DSP control panel and online debugging equipment, wherein the DSP control panel is arranged below the oil field well; the online debugging equipment is arranged outside the oilfield well; and the online debugging equipment is in communication connection with the DSP control board through the LIN bus.

Preferably, the online debugging equipment is used as ground equipment of the oilfield well and is connected to an upper computer of a computer through an LIN bus-to-USB module.

Preferably, the LIN bus comprises three wires, two supply wires: v, GND and a communication bus, connecting the GND and the communication bus to a DSP control panel below the oilfield well, and establishing communication between the DSP control panel and the online debugging equipment.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the single-bus online programming device has the advantages that due to the fact that underground space is limited, the number of the wire cores which can be led out is very limited, the device adopts an LIN protocol communication mode, communication connection is built between the DSP control board and the online debugging equipment through the LIN bus, the LIN bus is low in cost and wide in application range, commands are sent to the underground DSP control board through the online debugging equipment, data transmission and verification work is completed, and therefore online programming of DSP chips in the DSP control board is achieved.

Drawings
