Abstract

The utility model relates to an equipment operation temperature prober, comprising a temperature sensor circuit and a central processor control circuit. Output signals of the temperature sensor circuit are transmitted to the central processor control circuit by sequentially passing through a comparer circuit and an A/D (Analogue/Digital) data converting circuit; output signals of the central processor control circuit are sent to a driving circuit and a ZigBee wireless module circuit in a controlled manner; and output signals of the ZigBee wireless module circuit are sent to a data processing center. According to the equipment operation temperature prober provided by the utility model, temperature signals of equipment are collected by using a temperature sensor. When the equipment is at an abnormal operation temperature, alarming signals are emitted, a power source is switched off, and the safe operation of the equipment is ensured.

Description of drawings
Fig. 1 is the frame assumption diagram of the utility model;
Fig. 2 is the circuit theory diagrams of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to specify.
Like Fig. 1, shown in Figure 2; A kind of equipment operation hygrosensor of the utility model; Comprise temperature sensor circuit 1 and central processing unit control circuit 2; The output signal of said temperature sensor circuit 1 transfers to central processing unit control circuit 2 through comparator circuit 11, A/D data converting circuit 12 successively; The output signal controlling of said central processing unit control circuit 2 is sent to driving circuit 21 and ZigBee wireless module circuit 22, and the output signal of said ZigBee wireless module circuit 22 is sent to data processing centre (DPC) 221, said central processing unit control circuit 2 also with watchdog circuit 3 bidirectional data communications.
Said temperature sensor circuit 1 adopts LM35 temperature sensor IC1 collecting temperature signal, the built-in amplification of LM35 temperature sensor IC1, level shift and paraphase, and after its Signal Regulation, 1 ℃ every liter of temperature, output just increases 10mv.Therefore for 0 ℃ to 100 ℃ temperature range, the respective output voltages scope is 0V to 1V.Said comparator circuit 11 adopts CA3130 operational amplifier IC2, and the voltage detecting level of CA3130 operational amplifier IC2 is compared the output voltage of temperature sensor with the reference voltage that comparer presets, like the output voltage of LM35 temperature sensor IC1 above reference voltage; Then the output of CA3130 operational amplifier IC2 uprises, and this signal is input to the 2nd pin of A/D data conversion module IC3, after its inner A/D conversion; The 35th, 36,37 pin by its 5th, 6,7 pin and 89S52 single-chip microcomputer IC5 are formed datel circuit; For after surpassing the temperature value of setting, divide two-way to send control signal through 89S52 single-chip microcomputer IC5 internal judgment, first via output; The 26th pin output low level signal by 89S52 single-chip microcomputer IC5; Through resistance R 8 current limlitings, transistor Q1 is ended, relay J discharges; Its contact J-1 breaks off, and contactor KM cuts off the apparatus of load power supply; The second tunnel output; Form ZigBee wireless module circuit 22 by the 6th, 7 ends of ZM2410 wireless communication module IC6 and the 10th, 11 ends of 89S52 single-chip microcomputer IC5; ZM2410 wireless communication module IC6 is the embedded serial ports transparent transmission of the Zigbee of built-in 2.4GHZ (some multiple spot and point-to-multipoint) communications protocol; Support aerial upgrade firmware or configuration far module information, the receiving sensitivity up to the power output of 7dBm and-100dBm can satisfy telecommunication; Send the AT instruction by 89S52 single-chip microcomputer IC5 ZM2410 wireless communication module IC6 is realized wireless data transceiving; Switch pin with the RS-485 direction, send current warning message, reach the remote supervisory and control(ling) equipment running state information to the data alarm center.
Form watchdog circuit by watchdog module IC4 and 89S52 single-chip microcomputer IC5; Form reset circuit by resistance R 6, capacitor C 2; Reset circuit to the 7th pin of the 9th pin of 89S52 single-chip microcomputer IC5 and watchdog module IC4 prevents that 89S52 single-chip microcomputer I C5 internal processes is in the endless loop state.
An above-described preferred embodiment that is merely the utility model can not limit the scope that the utility model is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
