Abstract
The utility model relates to a thermometer for a train shaft with compatible digital and analog two sensors. A temperature sensor installed on the train shaft is connected with a signal processing unit through an interface, and the temperature sensor installed on the train shaft is connected with a central processor and a working unit. An analogue signal processing unit and a digital signal processing unit are in parallel connection between the sensor interface and the central processor, and the temperature sensor by type is respectively connected with one of the analogue and the digital signal processing units. Two signal processing units are connected with the central processor through a change-over switch. The design solves the problem of the temperature monitor device of the train of railway adopt the temperature sensor. The device is regardlessly installed on a vehicle with any sensor, and the device can normally proceed monitoring the journal temperature.
Description
The utility model relates to a kind of railway train shaft temperature monitoring device, the train axle temperature monitoring device of particularly a kind of energy compatible with digital, two kinds of sensors of simulation.
The train axle temperature monitoring device is the necessary device that guarantees the train safe operation, its structure is: the temperature sensor that is installed on the axletree connects a signal processing unit through interface, connect the center processor that constitutes by single-chip microcomputer again, working cells such as center processor is taking alarm, communication, demonstration.Temperature sensor wherein has a lot of types, as platinum resistance, thermistor, current mode integrated sensor A0590, and the semiconductor PH junction temperature sensor that was generally adopted up to nearly ten years.The common feature of these sensors is the analog quantitys that temperature transition become types such as electric current, voltage, resistance.Along with the development of technology, the numeric type temperature sensor occurred in recent years, it is in sensor temperature transition to be become digital quantity, reads for secondary instrument with serial mode.Obviously, this sensor has saved analog to digital conversion and signal Processing link than the temperature sensor of analog quantity, and its antijamming capability obviously strengthens simultaneously.So digital temperature sensor is subjected to the hig diligence of railway interests, there are some train axle temperature monitoring devices to adopt digital sensor.From development, digital transducer has the trend that replaces analog sensor, but the practical problems that faces at present can not be ignored: one, from economic angle, it is several hundred million that the analog sensor device for detecting temperature total value used of the whole nation reaches, and it is impossible upgrading immediately comprehensively.Replace as adopting progressively, the scheme of Tao Taiing in batches, then have in a very long time, two kinds of sensors use on different vehicles simultaneously, when two kinds of vehicles that different sensors is housed often mix marshalling together, get rid of extension, when organizing into groups again, the incompatible problem of sensor and communication thereof can't solve.Its two, from technical standpoint, can digital sensor adapt to the abominable working environment on the train, remains to be tested by practice.Simultaneously, can digital sensor just can judge its quality as analog sensor with simple means, also affects the popularization of digital sensor.In a word, railroad train is being selected for use on digital sensor or the analog sensor problem, the selection of facing a difficult choice occurred.
Task of the present utility model is to solve railroad train in a difficult problem of selecting for use on digital sensor or the analog sensor problem, the train axle temperature monitoring device of a kind of energy compatible with digital, two kinds of sensors of simulation is provided, no matter this device is contained on the vehicle of being furnished with which kind of sensor, can both normally carry out the monitoring of axle temperature, provide technical conditions for the vehicle of being furnished with different sensors mixes marshalling.In this marshalling, the work such as communication, control, demonstration and warning between each car body attemperating unit all can normally be carried out.
The present techniques scheme is: the train axle temperature monitoring device of compatible with digital, two kinds of sensors of simulation: the temperature sensor that is installed on the axletree connects a signal processing unit through interface, connect center processor again, center processor connects the working cell, it is characterized in that: between sensor interface and center processor, be parallel with analogy signal processing unit and digital signal processing unit, temperature sensor connects one of them signal processing unit respectively by kind, and two signal processing units are connected with center processor through switch.Here said switch can be different switches such as rotary switch, waver, jackswitch, chopper switch, can also be without switch, and methods such as employing wiring realize that one of two signal processors are connected with the selectivity of center processor.
The energy compatible with digital that the utility model provides, the train axle temperature monitoring device of two kinds of sensors of simulation, the device for detecting temperature that has solved railroad train is selected the difficult problem of temperature sensor for use, no matter this device is contained on the vehicle of being furnished with which kind of sensor, the bearing temperature monitoring that can both normally carry out provides technical conditions for the vehicle of being furnished with different sensors mixes marshalling.In this marshalling, the work such as communication, control, demonstration and warning between each car body attemperating unit all can normally be carried out.
Now be described further with embodiment in conjunction with the accompanying drawings.
Fig. 1 is the application's fundamental diagram.
Embodiment 1, and with reference to Fig. 1, the train axle temperature monitoring device of compatible with digital, two kinds of sensors of simulation: the temperature sensor that is installed on the axletree connects center processor through interface, and this center processor is made of a single-chip microcomputer.Single-chip microcomputer connects the working cell again.There is communication device working cell in this example, warning circuit, display device and button equal controller.It is characterized in that: between sensor interface and center processor, be parallel with analogy signal processing unit and digital signal processing unit, temperature sensor connects one of them signal processing unit respectively by kind, and two signal processing units are connected with center processor through switch K.
Claims (2)
1, the train axle temperature monitoring device of a kind of compatible with digital, two kinds of sensors of simulation: the temperature sensor that is installed on the axletree connects a signal processing unit through interface, connect center processor, center processor connects the working cell, it is characterized in that: between sensor interface and center processor, be parallel with analogy signal processing unit and digital signal processing unit, temperature sensor connects one of them signal processing unit respectively by kind, and two signal processing units are connected with center processor through switch.
