Sensor 3, second temperature sensor 4, the first warning light 5, the second warning light 6, wireless module 7 and receiving instrument 8；For keeping bin
The heating temperature control device 2 of temperature in 12, the first temperature sensor 3 of heating temperature control device 2 can be gathered, temperature in bin 12 can be gathered
Second sensor is installed in bin 12；The input of single-chip microcomputer 1 is sensed with the first temperature sensor 3, second temperature respectively
Device 4 is connected；The output end of single-chip microcomputer 1 respectively with heating temperature control device 2, the first warning light 5, the second warning light 6, the phase of wireless module 7
Even, wireless module 7 is connected with receiving instrument 8 by wireless signal.
During work, single-chip microcomputer 1 gathers the temperature of heating temperature control device 2 by first sensor, is gathered by second sensor
Temperature in bin 12.
As shown in figure 3, monitoring system one：When the temperature in bin 12 is less than setting value T1, single-chip microcomputer 1 is opened by circuit
Dynamic heating temperature control device 2；After the temperature in bin 12 reaches normal value, single-chip microcomputer 1 closes heating temperature control device 2 by circuit；When
When temperature in bin 12 is less than setting value T2, single-chip microcomputer 1 sends " low-temperature warning of bin 12 " signal by wireless module 7.
Monitoring system two：When the temperature in bin 12 is less than setting value T1, single-chip microcomputer 1 passes through circuit start heating temperature control
Device 2；After heating temperature control device 2 starts, when the temperature on the surface of heating temperature control device 2 is less than setting value T3, illustrate that heating temperature control device 2 is damaged
Bad or circuit is obstructed, now controls the first warning light 5 to flash by single-chip microcomputer 1, and sends " failure " letter by wireless module 7
Number；After heating temperature control device 2 starts, when the temperature on the surface of heating temperature control device 2 is higher than setting value T3, heating temperature control device 2 is being illustrated just
Often start, after waiting one to ten minute（Determined according to the model of heating temperature control device 2）, the temperature in bin 12 is less than setting value T4
When, the underpower of heating temperature control device 2 is illustrated, now control the second warning light 6 to flash by single-chip microcomputer 1, and by wireless module 7
Send " underpower " signal.
The various signals of two kinds of monitoring system monitorings send to duty personnel is hand-held and receive on instrument, are capable of achieving self-inspection each
Class failure, can interpolate that out the failure of heating temperature control device 2 and underpower, moreover it is possible to find the low temperature hidden danger of bin 12 in time；Simultaneously
Accomplish information real time on-line monitoring, make that duty personnel is rapid, accurately know operation conditions, the failure cause of equipment, so as to and
