Embodiment
For further disclosing technical scheme of the present invention, elaborate through embodiment below in conjunction with Figure of description:
As shown in Figure 1; The present invention includes switch board, power supply, core control panel, temperature sensor, flexible heater and aerofoil fan; It is characterized in that on the circuit control panel in the switch board housing or be provided with the core control panel of the temperature control system of switch board on the inwall; Be located at temperature sensor in the switch board, be located at flexible heater and aerofoil fan on the switch board housing wall; As shown in Figure 2; The core control panel comprises singlechip controller, temperature sensor inputs that links with singlechip controller, the charactron display unit, state of temperature lead-out terminal, the relay drive unit that link with unit machine controller output terminal; The relay group that links with relay drive unit; With power input terminal, radiator fan lead-out terminal, the fan failure detecting unit of relay set associative, the power input terminal that links with the radiator fan lead-out terminal, the well heater lead-out terminal that links with power input terminal; Also comprise the AD converter that links with temperature sensor inputs; AD converter and singlechip controller link, and link with the single nothing of fan failure detecting, and fan failure detecting unit and radiator fan lead-out terminal link; The environment temperature that measures through the real-time monitor temperature sensor of core control panel; And show through the charactron display unit; When environment temperature is higher than the high temperature warning value that on singlechip controller, sets or is lower than the low temperature warning value; Singlechip controller startup aerofoil fan or flexible heater are lowered the temperature or are heated up, and guarantee that the instrumentation in the outdoor switch board is in the temperature environment of operate as normal.
As shown in Figure 3; After unit machine controller initialization was accomplished, system read current temperature value, and is shown on the charactron; And get into the alarm decision stage; When temperature is higher than (or being lower than) setting value, start radiator fan (or flexible heater), if system is several fans (or flexible heater) configuration; Each fan (or flexible heater) will adopt the delayed startup mode to start one by one, cause to prevent that several fans (or flexible heater) from starting simultaneously that immediate current is excessive to cause big current interference to system.
After fan (or flexible heater) starts, detect primary air fan (or flexible heater) running status 30 seconds, offer singlechip controller after with the conversion of fan (or flexible heater) work numerical value and normal value compares through AD converter through the every interval of timer interrupt mode; Error will not done any action in allowed band; Continue to keep watch on its duty, after error exceeded allowed band, system returned DTC; Show through charactron; System will stop all external outputs under the critical conditions, preserve current DTC, supply the maintainer to carry out Maintenance and Repair.
The workflow explanation:
System power-up: comprise DC24V and DC5V, DC24V is that radiator fan and flexible heater provide working power; DC5V is that core board provides the control power supply.
1. system initialization: singlechip controller operation initialize routine; Detect each temperature sensor state, detect each road output state, and the entire system state is externally exported through the running status output interface; If any fault, through 2 bit digital display display system failure code.
2. operation control: system detects Current Temperatures through temperature sensor, and takes turns to show through charactron, judges then whether temperature value exceeds limits value, if transfinite the start-up control of carrying out fan or well heater.
3. process detects: under radiating state; It is the radiator fan opening; System will be through the current detection circuit detecting fan running current of fan; And convert the current value that detects into numeral through AD converter and send to singlechip controller, singlechip controller analyzes the fan running status according to numerical values recited, will carry out the DTC feedback if any fault.
