Description

Diesel engine crank-pin spilled oil temperature-detecting device

Technical field

The utility model relates to a kind of diesel engine crank-pin spilled oil temperature-detecting devices.

Background technique

Diesel engine crank-pin spilled oil temperature-detecting device is usually certain external producer's monopolization manufacture, utilizes temperature sensor Reading, carry out the realization of each channel temperature reading, average value, deviation, utilize above data carry out channel in high temperature report Alert, deviation alarm and parking compensate value using data and are arranged, and carry out Long-range Data Transmission, however existing product misses Report rate is high, and the external product order cycle time, cost price is excessively high, and the producer not according to reality continue to the product into Row updates, and the component and program used is still earlier version；The cooperation of available liquid crystal screen is not intuitive by key control trouble, behaviour Make complicated；Scalability is low.

As a result, it is necessary to propose a kind of novel diesel engine crank-pin spilled oil temperature-detecting device, to overcome the prior art Existing drawback.

Utility model content

The purpose of this utility model is to provide a kind of diesel engine crank-pin spilled oil temperature-detecting device, reduce rate of false alarm and Production cost, easy to operate, scalability is high.

To reach the utility model aim, the utility model is provided the following technical solutions: a kind of diesel engine crank-pin spilled oil Temperature-detecting device comprising: power circuit, the one-chip computer module being connected with power circuit, be connected with one-chip computer module it is logical News module and the thermal module for being directly connected and passing through sensor thermometric with one-chip computer module.

Based on the above technical solution, it further includes the following affiliated technical solutions:

The power circuit include DC power supply, the PS module being connected with DC power supply and with PS module anode output phase Diode even, wherein PS module is built-in with filtering and isolated location.

The one-chip computer module model CPU1214C, the communication module model CSM1277, the thermal module type Number be SM1231.

It further comprises touch screen, multiple relays and miniature circuit breaker.

Due to having used above technical scheme, the utility model rate of false alarm is substantially reduced, and has been saved cost, has been reduced system Fault point, easy to operate, monitoring is convenient, abundant before ratio.

Detailed description of the invention

It is described in detail below in conjunction with technical solution of the drawings and specific embodiments to utility model, so that this is practical Novel characteristic becomes apparent with advantage.

Fig. 1 is the circuit diagram of power circuit in the utility model；

Fig. 2 is the circuit diagram of one-chip computer module and communication module in the utility model；

Fig. 3 is the circuit diagram of thermal module in the utility model；

Fig. 4 is the main view of the utility model.

Specific embodiment

Detailed description will be provided to the example of the utility model below.Although the utility model will combine some specific realities The mode of applying is illustrated and illustrates, but should be noted the utility model not merely current situation in these embodiments.Phase Instead, the modification or equivalent replacement carried out to the utility model, should all cover in the scope of the claims of the utility model.

In addition, in order to better illustrate the utility model, given in specific embodiment below numerous specific Details.It will be understood by those skilled in the art that without these details, the utility model equally be can be implemented.In the present embodiment In, well known structures and component are not described in detail, in order to highlight the purport of the utility model.

As shown in Figures 1 to 4, the utility model provides a kind of specific reality of diesel engine crank-pin spilled oil temperature-detecting device Apply example comprising power circuit, the one-chip computer module being connected with power circuit, the communication module being connected with one-chip computer module, with And directly it is connected and passes through the thermal module of sensor thermometric with one-chip computer module.

Power circuit includes 24 volts of DC power supplies, the PS module being connected with 24 volts of DC power supplies and defeated with PS module anode Connected diode V1 out.Wherein PS module is built-in with filtering and isolated location.

One-chip computer module model CPU1214C, communication module model CSM1277, thermal module model SM1231.

Preferably, the utility model further comprise touch screen, multiple relay K1-K6 and miniature circuit breaker CP1, CP2。

The utility model utilizes filtering and isolated location in PS module, and the sensor in thermal module is read the number of coming According to being filtered, the excessive too small invalid data of data to happen suddenly in per continuous 10 data is filtered out, is greatly reduced Report number by mistake, while the step of eliminating PT100-4~20Ma in the prior art conversion, every set equipment reduces 8 pipeline equipments, Reduced cost decreases fault point simultaneously.Simultaneously replaced the display screen that original liquid crystal adds key, using touch screen as show Show equipment, display is more intuitive, operates simpler.In addition original 2 extension points are increased to 4, increases expanding for system Malleability.

The utility model rate of false alarm substantially reduces, and has saved cost, reduces system failure point, easy to operate, monitoring side Just, abundant before ratio.

Certainly the above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with this The people of technology can understand the content of the utility model and implement accordingly, and the protection model of the utility model can not be limited with this It encloses.The equivalent transformation or modification that all Spirit Essences according to the utility model main technical schemes are done, should all cover in this reality Within novel protection scope.
