Above-mentioned Fig. 1-Fig. 8 is described air channel design, ventilation unit and the communication backup battery indoor and outdoor integrated system of ventilating system; Solve the supporting device systems of backup battery in the prior art outdoor can't normal mounting and use, defective such as fault easily.The present invention can reduce the probability of backup battery burning so that reach vacuum state in the battery bay through the air channel design.And the cold and hot air channel of the two-way antithesis ventilation unit at top and middle part is controlled through the environmental monitoring unit in the integral system; Like the startup of the wind direction of fan, semiconductor refrigerating backing, stop etc.; Thereby control the second cabin body, reach constant, further reduce the equipment compartment indoor/outdoor temperature-difference like the temperature in the equipment compartment; Integrated numerous equipment in the integrated communication base station cabinet in the solution prior art; Can go into hot environment during equipment operation, and the temperature difference of equipment compartment inside and outside medium is big, causes the technical barrier of equipment fault.

Be described in detail how equipment compartment (the second cabin body) to be carried out thermostatic control through Fig. 9 below through the environmental monitoring unit.

Fig. 9 is an environmental monitoring unit embodiment electrical block diagram among Fig. 1.As shown in Figure 9, the environmental monitoring unit of present embodiment is used to measure ventilating system body inside, second cabin or ambient temperature, and satisfies when pre-conditioned in ambient temperature, starts ventilating system, and the second cabin body is carried out thermostatic control.

Particularly, the environmental monitoring unit can comprise:

Temperature collect module is used to measure the inside or the ambient temperature of ventilating system;

Processing module is used for the measurement result according to temperature collect module, compares with preset condition, and the control fill order takes place;

The control Executive Module is used for the control fill order according to processing module, and wind direction, air baffle and/or the semiconductor refrigerating backing of the bidirectional active fan of the two-way cold and hot air channel of antithesis ventilation unit starts or stops in the control ventilating system.

Because the control circuit of semiconductor refrigerating backing belongs to existing common technology; Therefore the present invention does not do the introduction of emphasis; Temperature-measuring module mainly is a temperature of measuring batteries among Fig. 9, and input processing module controls, in another piece of the applicant patent for the control of accumulator cell charging and discharging; Little with the application's relation, be not described in detail.Introducing the physical circuit of temperature collect module and processing module, control Executive Module below forms.The temperature collect module of present embodiment can be to increase by one group of temperature probe at equipment compartment; And send control execution signal by single-chip microcomputer P89LPC936FA processing module and control No. 1, No. 2 bidirectional active fans and No. 3, No. 4 bidirectional active fans as shown in Figure 4 for the control Executive Module, and two air baffles, semiconductor refrigerating heating plates are worked.

As shown in Figure 9, temperature control is formed core processing module by single-chip microcomputer P89LPC936FA, digital-to-analogue conversion TLC0548 in the ventilating system; Form temperature collect module by computing amplification AD524, binary inner bag temperature sensor AD 590; Reach by photoelectricity isolation moc3041, controllable silicon BT138-800 and form control Executive Module etc.

Like Fig. 9, through the real-time collecting device of temperature collect module cabin temperature data, convert digital signal into through TLC0548.A/D then, send among the single-chip microcomputer P89LPC936FA, a part is sent to demonstration then; Another part with carry out thermostatically controlled set point, for example the preset temperature of indoor temperature and/or the temperature gap of indoor and outdoor temperature difference compare, and obtain control signal and via single-chip microcomputer output two-way.The control of the forward of No. 1 No. 2 bidirectional active fans of one tunnel control and reverse operation and air stream baffler direction, No. 3 No. 4 bidirectional active fan works of another road control.Specifically can be referring to the introduction of facing constant-temperature control method down.

As shown in Figure 9, the data acquisition module circuit is mainly by AD590, compositions such as AD524A.Because it is 0.1 degree that control precision requires, and considers to measure and disturb and the data processing error, then the precision of temperature sensor and AD converter should the higher realization that could guarantee control precision, and this precision can be located to be decided to be roughly 0.1 and spend.So temperature sensor needs to distinguish 0.1 degree; And for AD converter, because measuring range is the 40-90 degree, with the AD discrimination requirement of 0.1 degree as response, then AD needs to distinguish (90-40)/0.1=500 digital quantity, obviously needs the AD converter more than 10.Therefore, present embodiment is selected high-precision 12 AD524A for use.

Figure 10 is a temperature collect module circuit structure embodiment sketch map.This circuit mainly is made up of temperature sensor AD 590 and differential operational amplifier AD524, and wherein temperature sensor AD 590 is a kind of novel two ends formula constant current device.Actuation voltage range is 4～30V, and temperature-measuring range is-55～+ 150 ℃.When the electric current of AD590 flows through the resistance of a 10k Ω, temperature rising 1K, this ohmically voltage increases 5mV, promptly converts 5mV/K to.Therefore, when temperature changed between 0～100 ℃, resistance voltage changed between 1.365～1.865V.Operational amplifier A D524 is used for converting absolute temperature to Celsius temperature.

The electric current that flows through AD590 is directly proportional with thermodynamic temperature, and when the resistance sum of resistance R 6 and potentiometer R7 was 1kW, output voltage VO (2 output voltage in the middle of R6 and the R7) was 1mV/K with variation of temperature.But because the gain of AD590 has deviation, resistance also has error, therefore tackles circuit adjustment.The method of adjustment is: be put in AD590 in the mixture of ice and water, adjustment potentiometer R5 makes VO=273.2mV.Or at room temperature adjust potentiometer under (25 ℃) condition, make VO=273.2+25=298.2 (mV).But adjustment guarantees near 0 ℃ or 25 ℃, degree of precision is arranged only like this.

Potentiometer R9 is used to adjust zero point, and R8 is used to adjust the gain of amplifier AD524.Method of adjustment is following: adjustment R2 in the time of 0 ℃, make output VO=0, and adjustment R4 makes VO=100mV in the time of 100 ℃ then.So repeatedly adjustment repeatedly, in the time of 0 ℃, VO=0mV is in the time of 100 ℃ till the VO=100mV.At room temperature carry out verification at last.For example, if room temperature is 25 ℃, VO should be 25mV so.Mixture of ice and water is 0 ℃ of environment, and boiling water is 100 ℃ of environment.

Make among the figure that 2 voltage is 200mV/ ℃ for output VO in the middle of the R6 and R7, can realize through increase feedback resistance (feedback resistance is in series by R7 and potentiometer R6 among the figure).In addition, when measuring Fahrenheit temperature (symbol be a ° F), deduct 255.4 and multiply by 9/5 again,, then adjust feedback resistance and be about 180kW, make when temperature is 0 ℃ VO=17.8mV so be output as 1mV/ ° of F as if requirement because of Fahrenheit temperature equals thermodynamic temperature; When temperature is 100 ℃, VO=197.8mV.

Figure 11 is control Executive Module electrical block diagram.Mainly form by two photoelectrical coupler MOC3041 and two BT138-600 controllable silicons, shown in figure 11.The control signal that single-chip microcomputer sends (PWM) is controlled the operating state of photoelectrical coupler behind driver.After photoelectrical coupler work, make the The Trigger of Bidirectional Triode Thyristor utmost point be in high level, controllable silicon is in conducting state, and then controls No. 1 No. 2 No. 3 No. 4 bidirectional active fans and the work of semiconductor refrigerating backing.

Controllable silicon BT138-600 and MOC3041 can think that linear link realizes the control to fan and semiconductor refrigerating backing.Single-chip microcomputer output semiconductor refrigeration backing and fan power belong to light current and strong power part respectively, need carry out isolation processing.Here adopt optic coupling element MOC3041 to carry out photoelectricity and isolate, adopt transformer and BRIDGE2 rectifier to isolate the isolated from power that realizes weak forceful electric power jointly in addition at control section.Single-chip Controlling signal PWM output level is 0 o'clock; The optic coupling element conducting, thus make the PD7 triode form effective biasing and conducting, and the voltage through rectifier bridge is through collector resistance and penetrate the collection reverse biased; There is the voltage about 7V to be added in the bidirectional triode thyristor control end; Thereby make the controllable silicon conducting, alternating current path forms, fan work; Otherwise the single-chip microcomputer output level is 0 o'clock, and optic coupling element can not conducting, and triode can not form effective biasing and end, and the SCR control terminal voltage is almost nil, thereby controllable silicon blocks alternating current path, and fan quits work.The control circuit of forward and reverse fan rotation mainly is made up of 74LS00TTL 2 inputs four NAND gate integrated circuits.

The Port1 pin is a fan traffic direction signal input part, and 2 pin are controllable silicon signal input parts, and 3 pin are ground wires.Notice that the Port3 pin has connected a R9, the i.e. resistance of 2k Ω over the ground.When the drive plate that turns to of control fan was supplied power respectively with single-chip microcomputer, this resistance can provide the path of signal code backflow.When drive plate and one group of power supply of one-chip machine common, this resistance can prevent that big electric current from causing interference along the ground wire that line flows into the single-chip microcomputer mainboard.In other words, be equivalent to separate the ground wire of the ground wire of drive plate and single-chip microcomputer, realize " one point earth ".

The drives that triode and resistance, diode are formed realizes the rotating of fan electromotor adjustable speed is driven.Four diodes play the protection triode, prevent the impact of the negative induced electromotive force of inductive element (fan electromotor) generation to triode.

When single-chip microcomputer output control signal 74LS00 output was low level, Q2, Q4 ended, and Q1, Q3 conducting are output as high level.1, No. 2 A the group fan be rotated in the forward. when single-chip microcomputer output control signal 74LS00 output is high level, Q2, Q4 conducting, Q1, Q3 end, and are output as low level, the fan reverse rotation.
