Brief description of the drawings
Fig. 1 is the utility model structural principle block diagram.
Embodiment
With reference to Fig. 1, by embodiment, the utility model is further described.
As shown in figure 1, a kind of mining temperature sensor that the utility model is provided, mainly by signal transacting display circuit and
Digital temperature probe 9 is constituted, and whole sensor is powered by external power source 2：
Wherein signal transacting display circuit by light-emitting diode display 1, voltage stabilizing IC chip 3, key circuit 4, single-chip microcomputer 5, passive connect
Point output circuit 6,200~1000Hz frequency output circuitries 7 and memory 8 are constituted, during normal work, and digital temperature probe 9 is visited
The environment temperature measured is converted into electric signal storage and arrived inside it, and this electric signal sends order through single-chip microcomputer 5 and read, then through LED
Display 1 is shown, and is exported through 200~1000Hz frequency output circuitries, and voltage stabilizing IC chip 3 carries out voltage stabilizing simultaneously to external power source 2
Voltage needed for signal transacting display circuit is converted into, key circuit 4 mainly has temperature alarming point to set and analog warning test work(
Can, no source contact output circuit 6 is when sensor temperature is alarmed, and contact state changes（It is normally opened to become normally closed or normally closed change often
Open）, temperature alarming value of the memory 8 for storing setting.
Finally it should be noted that：Above example only not limits the utility model and retouched to illustrate the utility model
The technical scheme stated；Therefore, although this specification has been carried out detailed description to the utility model with reference to the above embodiments,
But, it will be understood by those within the art that, still the utility model can be modified or equivalent substitution；And one
The technical scheme for not departing from spirit and scope of the present utility model and its improvement are cut, it all should cover in right of the present utility model
In claimed range.
