Background technology
The medium-to-high grade electronic stop plate of prior art all is furnished with the control system of information demonstration and data transmission, and control system all can be emitted heat in operational process, electronic stop plate is mainly used in the open air in addition, for hot season, under the condition of direct sunlight, the temperature inside the box can be too high, because the electric components of control system can only be worked in certain temperature range, if the temperature inside the box is too high, will affect the normal operation of control system; In addition, for cold season, especially the winter in the north, outdoor temperature is excessively low, can cause electronic stop plate the temperature inside the box to cross low and affects control system and normally move.Application number is that 201120393696.0 utility model patent discloses " a kind of electronic bus-stop board cabinet ", this electronic bus-stop board cabinet comprises rectangular cabinet, be provided with the first radiator fan at the top of rectangular cabinet, in the bottom of rectangular cabinet the second radiator fan is installed, by means of two radiator fans, the heat that main frame in the cabinet produces can be left.But this cooling measure has significant limitation, surpasses the heat radiation limit of two radiator fans, does not just reach the effect that reduces temperature, and, because therefore the measure that do not heat up does not then have any effect for the excessively low situation of temperature.In sum, the prior art that comprises above-mentioned patent, owing to there is not temperature controlled measure, can't resolve the too high or too low problem of outdoor electronic station board the temperature inside the box in the outdoor electronic station board case, can not satisfy the actual needs of outdoor electronic station board case controlling system operation.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art and defective, provide a kind of and can solve the too high or too low problem of outdoor electronic station board the temperature inside the box, and a kind of outdoor case temperature monitoring system simple in structure and easy for installation.
The technical scheme that the utility model is taked comprises embedded microprocessor; the temperature sensor that is used for Real-time Collection the temperature inside the box data is connected with embedded microprocessor; embedded microprocessor is connected with serial communication interface is two-way; embedded microprocessor also is connected with driving circuit; driving circuit is connected with overload protecting circuit again, and described overload protecting circuit also is connected with carbon fiber heating plate with radiator fan respectively.
Compared with prior art, the beneficial effects of the utility model are, data by temperature sensor Real-time Collection the temperature inside the box, by embedded microprocessor temperature is regulated and control, simultaneously can also temperature data be sent to host computer by serial communication interface, realized the monitoring of the temperature inside the box, solved well the uncontrollable present situation of outdoor electronic station board the temperature inside the box, have simple in structure, adjustment is flexible, be swift in response, advantage easy for installation and applied widely, can be installed in the outdoor electronic station board case of different structure, outdoor electronic station board the temperature inside the box is regulated and control.
Description of drawings
Fig. 1 is system architecture diagram of the present utility model;
Fig. 2 is workflow diagram of the present utility model.
Among the figure:
1. embedded microprocessor; 2. temperature sensor;
3. driving circuit; 4. serial communication interface;
5. overload protecting circuit; 6. radiator fan; 7. carbon fiber heating plate.
Embodiment
As shown in Figure 1; the utility model comprises embedded microprocessor 1; the temperature sensor 2 that is used for Real-time Collection the temperature inside the box data is connected with embedded microprocessor 1; embedded microprocessor 1 and 4 two-way connections of serial communication interface; embedded microprocessor 1 also is connected with driving circuit 3; driving circuit 3 is connected with overload protecting circuit 5 again, and described overload protecting circuit 5 also is connected with carbon fiber heating plate with radiator fan 6 respectively and is connected.
During work, embedded microprocessor 1 is by temperature sensor 2 collecting temperature data, processed after the data acquisition, and at a certain time interval, send temperature data by serial communication interface 4 to host computer, judge Current Temperatures according to the data that collect simultaneously, if temperature value surpasses default higher limit or lower limit, be dangerous values, then send warning message by serial communication interface 4 to host computer, send according to temperature value simultaneously and drive signal, drive signal and drive radiator fan 6 or carbon fiber heating plate 7 work through overdrive circuit 3, specifically, when temperature surpasses default higher limit, driving circuit 3 drives radiator fan 6, makes air formation convection current in the case, and by the louvre on the casing heat is left; When temperature was lower than default lower limit, driving circuit 3 drove carbon fiber heating plate 7 work, is used for heating, thereby makes the temperature inside the box reach normal value; And be provided with overload protecting circuit 5 in driving circuit 3 rear one-levels, in order to prevent from transshipping the damage that causes device and circuit board.
Figure 2 shows that workflow of the present utility model, after successfully reading out temperature value, by comparing with temperature upper limit and the lower limit preset, if temperature is not higher than higher limit, be not lower than simultaneously lower limit, then normally send temperature data to host computer by serial communication interface, do not carry out other operations; If temperature value surpasses one of default higher limit or lower limit, then send warning information by serial communication interface to host computer, again temperature data is compared afterwards, if be higher than higher limit, then start radiator fan, if be lower than lower limit then start carbon fiber heating plate.After starting radiator fan or carbon fiber heating plate, the interval certain hour is the collecting temperature data again, if temperature reverts to normal value, namely are lower than higher limit and are higher than simultaneously lower limit, then close radiator fan or carbon fiber heating plate, if temperature value still is dangerous values then proceeds the temperature control action.
The components and parts institute accepted standard of different manufacturers is different; take technical grade standard temperature scope-40 ℃ ~+85 ℃ as example; before the mxm. or minimum of components and parts working environment of living near this standard; temperature control system just must be taked the temperature adjustment measure; therefore; temperature upper limit and lower limit scope set in the utility model should be less than the nominal operation temperature ranges of claimed components and parts; equally take technical grade standard-40 ℃～+ 85 ℃ as example; the temperature upper limit that arranges in the utility model and lower limit can be-20 ℃～+ 60 ℃, and concrete settings will be decided according to practical situations.
The carbon fiber heating plate of selecting in the utility model dispels the heat with infrared mode, and the thermal efficiency is high, and is minimum for peripheral electronic devices and components radiation, and is long-pending light and handy, is convenient to use in the casing with narrow space.
