Description
Technical field
The invention belongs to temperature transmitter technical field, is related to the temperature transmitter that a kind of security performance improves.
Background technology
Temperature transmitter is the instrument with showing, extensive use by the laggard line number word processing of collecting temperature sensor signal
In the cryogenic gases such as natural gas, liquid nitrogen and cryogenic liquid measurement and situ industrial Row control.With the development of science and technology, these
Industrial production manufacture scene is operated and guarded without personnel, and is only needed by being wirelessly transferred, the skill such as remote monitoring
Art means are monitored to in-situ transducer.Temperature transmitter needs outwards to transmit data by remote transmission mode.Data pair
At present without encryption during outer transmission, this is just likely to be intercepted and captured by criminal, causes significant data to be revealed.If in addition, only
In external transmission, encryption can not prevent someone from opening data intercept after transmitter at the scene.
The content of the invention
To solve the above problems, the invention discloses high security temperature transmitter, not only in the outside of temperature transmitter
Encryption chip is provided with output channel, the sensor that can sense shell opening, Neng Gouji are provided with also inside transmitter
When send alarm.
In order to achieve the above object, the present invention provides following technical scheme：
High security temperature transmitter, including battery, processor, temperature sensor, AD Acquisition Circuit, output interface, encryption
Chip, wireless communication module, light intensity sensor, alarm modules, the temperature sensor are connected with AD Acquisition Circuit, the processing
Device is connected with AD Acquisition Circuit, encryption chip, light intensity sensor, alarm modules respectively, and the temperature sensor is used to gather temperature
Analog signal is spent, the AD Acquisition Circuit is used to temperature analog signal is converted into data signal and transmitted into processor, institute
Light intensity sensor is stated to be used to gather light intensity signal in transmitter enclosure body, the encryption chip respectively with output interface, radio communication
Module connect, the battery be transmitter in each power elements, the outside output data of output interface, the radio communication
Module is used for input and output wireless communication signal.
Further, in addition to encrypted memory, the encrypted memory are connected with processor.
Further, in addition to filtering Dolby circuit, the filtering Dolby circuit are connected to temperature sensor and AD collections
Between circuit, for being filtered noise reduction process to the signal that temperature sensor collects.
Compared with prior art, the invention has the advantages that and beneficial effect：
The live output interface and wireless communication module of wireless temperature transmitter provided by the invention are connected with encryption chip, are made
The safety of data transfer must be improved by signal that both modes export beforehand through just can externally be transmitted after encryption
Property, avoid live or air-data from being divulged a secret caused by being trapped afterwards.In addition, light intensity sensor is also provided with this transmitter,
When shell is opened, alarm modules can be triggered and send alarm, simultaneous processor also can be by wireless communication module to server
Give a warning；Meanwhile encrypted memory is also provided with transmitter, protection local datastore safety.
Brief description of the drawings
Fig. 1 is high security temperature transmitter structured flowchart provided by the invention.
Embodiment
Technical scheme provided by the invention is described in detail below with reference to specific embodiment, it should be understood that following specific
Embodiment is only illustrative of the invention and is not intended to limit the scope of the invention.
High security temperature transmitter, as shown in figure 1, including battery, processor, temperature sensor, AD Acquisition Circuit,
Output interface, encryption chip, wireless communication module, light intensity sensor, alarm modules, temperature sensor connect with AD Acquisition Circuit
Connect, processor is connected with AD Acquisition Circuit, encryption chip, light intensity sensor, alarm modules respectively, and temperature sensor is used to gather
Temperature analog signal, AD Acquisition Circuit are used to temperature analog signal is converted into data signal and transmitted into processor, light intensity
Sensor be used for gather light intensity signal in transmitter enclosure body and transmit into processor, encryption chip respectively with output interface, nothing
Line communication module connect, battery be transmitter in each power elements, the outside output data of output interface, wireless communication module use
In input and output wireless communication signal.At least one of WIFI module, bluetooth module, 3G/4G communication chips should be included.Alarm
Buzzer is preferably provided with module.
Preferably, the output interface is USB interface.
Operation principle of the present invention is as follows：
Temperature sensor collecting temperature analogue data, filtering Dolby circuit, which is filtered to the data after noise reduction process, to be transmitted to AD
Analog signal is converted into data signal by Acquisition Circuit, AD Acquisition Circuit, and the data signal is transmitted into processor.Processor
In data transfer enter in encrypted memory, simultaneous processor output data encrypted by encryption chip after by output interface and
Wireless communication module externally transmits.Light intensity sensor gathers light intensity signal in transmitter enclosure body and transmitted into processor, handles
Device judges then to drive alarm modules alarm sounds sound when light intensity numerical value exceedes the threshold value pre-set, while by being wirelessly transferred
Module sends alarm signal to server.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned embodiment, in addition to
Formed technical scheme is combined by above technical characteristic.It should be pointed out that for those skilled in the art
For, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as
Protection scope of the present invention.
