The invention simplifies the system structure, can greatly improve the performance of a locomotive control system, reduces the system failure rate, improves the control precision and stability, reduces the consumption of materials and spare parts, reduces the operation cost, and greatly improves the operation time and the operation rate of the locomotive.
Description
Technical field
The invention belongs to the diesel locomotive automation field, relate in particular to a kind of for diesel locomotive profit temperature control system and control method.
Background technology
At present, the oil of domestic Methods At Metallurgical Transportation Enterprise diesel locomotive, coolant-temperature gage control system all adopt the temperature sensor of 7 switching value outputs, wherein: coolant-temperature gage is used 5 temperature sensors to be gathered and control, when 20 ℃, 60 ℃, 78 ℃, 85 ℃ of corresponding water temperatures and 90 ℃, by switching value, exported respectively.Oil temperature is used 2 temperature sensors to be gathered and control, and during 110 ℃, 120 ℃ of corresponding oil temperatures, by switching value, is exported respectively.Because the control of profit temperature has adopted nearly 7 temperature sensors, and this temperature sensor precision and reliability not high, in operational process, failure rate is higher, brings inconvenience not only to the transportation organization of production, and causes the increase of maintenance capacity and cost.Therefore, need a set of more accurate and advanced profit temperature control system badly, to guarantee carrying out smoothly of transportation production.
Summary of the invention
The present invention aims to provide and a kind ofly can improve the temperature controlled accuracy and reliability of diesel locomotive profit, effectively reduces the locomotive failure rate, reduces spare parts consumption, improves motorcycle oil-water temperature control system and the method for locomotive operation rate.
For this reason, the solution that the present invention takes is:
A kind of motorcycle oil-water temperature control system, comprise computing machine and oily, the water lines be located on locomotive, it is characterized in that, a temperature transmitter of being powered separately by the DC24V direct supply is installed respectively on locomotive oil, water lines, set up one-chip computer module in locomotive computer, locomotive driving cabin arranges alarm, temperature transmitter connects one-chip computer module by the AD conversion unit circuit, in one-chip computer module, establishment has oil, coolant-temperature gage control program, and the one-chip computer module output terminal is connected with each reference mark and the alarm of locomotive respectively by control circuit.
The current mode temperature transmitter that described temperature transmitter is the linear output of analog quantity, output analog quantity current value is 4-20mA.
A kind of motorcycle oil-water temperature-controlled process, its concrete control procedure is:
Temperature transmitter converts the oil temperature that collects and water temperature to 4-20mA analog quantity current value and is exported, the AD conversion unit circuit converts the analog quantity current value to one-chip computer module that digital quantity signal sends locomotive computer to, one-chip computer module carries out computing and identification to the digital quantity received, and by control circuit, logic control and alarm is carried out in each reference mark of locomotive according to setting program:
When 20 ℃ of water temperatures, allow locomotive to play machine; In the time of 60 ℃, allow locomotive to load; In the time of 78 ℃, control the cooling of locomotive starting fan; Ring the alarm bell alarm in the time of 85 ℃; When water temperature reaches 90 ℃, the unloading of robot brain car diesel engine;
When torque converter working oil temperature reaches 110 ℃, the alarm alarm bell rings, and red led is bright, to the driver, gives a warning; When the working oil temperature reaches 120 ℃, control the diesel engine of locomotive unloading.
Beneficial effect of the present invention is:
The present invention has replaced 7 temperature sensors and supporting relay with 2 temperature transmitters, not only simplified system architecture, reduced spares reserve, and greatly improved the performance of locomotive control, the failure rate of effective reduction system, improve the precision and stability that profit is controlled, reduce material and spare parts consumption, reduce operating cost; In the time of can greatly improving the operation platform of locomotive and operating rate simultaneously.
The accompanying drawing explanation
Fig. 1 is motorcycle oil-water temperature control system structured flowchart.
