Background technology
Common fireman's switch power module, only has single output, if during as multichannel, must re-start and convert out other each road voltage, user's application is restricted, also having the user is not the research and development that the support product of Power Engineer is arranged entirely, thus the power conversion of settling a dispute by the parties concerned themselves exist on efficiency, the technical and first-class many beyond thought problems of stability.The fire-fighting control box of a complexity, need to all provide a road power supply output for each class function control circuit, and can mutually isolate, and what to the user, bring like this is apparent flexibly and conveniently.
The utility model content
The technical matters that the utility model solves is to provide a kind of built-in many output interlock power modules, can be by controller and affiliated such as the required power supply of printer, the required power supply of display screen, the power supply that control panel is required etc. all concentrates in module, only need the user that the supply lines access module of related circuit just can be realized, flexible.
For solving above technical matters, the utility model by the following technical solutions, a kind of built-in many output interlock power modules, it is characterized in that, comprise main electric input block, the EMI circuit, the processing and control element (PCE) that with described main electric input block, are connected, the PMW controller be connected with the EMC circuit, the charging road circuit be connected with the PMW controller and active and standby power conversion circuit, the standby electric input block be connected with charging road circuit, standby electric input block connects processing and control element (PCE), the DC-DC circuit be connected with active and standby power conversion circuit.
Described main electric input block comprises main electric input circuit, and with the main electric sample circuit that main electric input circuit is connected, the autonomous electric input circuit of main electric sample circuit sampling, transfer to processing and control element (PCE) by signal after main electric sample circuit sampling.
Described active and standby power conversion circuit connects the DC-DC circuit by switch.
Described DC-DC circuit has three road output voltages.
In three road output voltages of described DC-DC circuit, low-voltage circuit is carried out to current sample, and connect the DC-DC circuit control unit by the overcurrent control module.
One tunnel output of described DC-DC circuit is connected with warning circuit.
Described built-in many output interlock power modules also comprise overvoltage crowbar and current foldback circuit.
Good effect of the present utility model is:
Except main output, also has the multi-output power supply module of other several roads output.
The main output of power supply can be born 70% load, and having independently overcurrent or the short circuit on overload protection ability ，Zhe road does not affect other output.
Other output Zhong You mono-tunnel, road is for the control panel power supply, unaffected when main output short-circuit Shi，Zhe road, can not produce voltage and fall phenomenon.
Low pressure output is sampled with special-purpose current detection circuit when overcurrent, guarantees that power module is protected timely, is unlikely due to overcurrent or short-circuit current is excessive causes element to burn out or pcb board is damaged.
Power light draws from secondary output, only have all output all working properly it just normally light, input is arranged else if, it just flicker always report to the police.
The low and high level indication of three states is provided---main electric fault, standby electric fault, standby electric under-voltage, the user can remove to determine the level state of needed signal as required.
When not main electricity is inputted and reach shutoff voltage for electricity, turn-off output voltage, but continue to send alarm sound more than one hour.Remind the duty personnel to deal with an urgent situation.
The accompanying drawing explanation
Fig. 1 is the circuit function block diagram
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, civil power alternating current from the AC input end, carrying out rectifying and wave-filtering after the EMI circuit filters is DC high-voltage power supply, become the action of low-voltage pulse waveform of certain frequency after the power converter conversion, pulse waveform is subject to the modulation of PWM controller, pwm circuit, according to the result of the DC voltage sampling of output, determines pulse width, also just determines the height of output voltage.If this voltage sample loop has gone out accident, cause voltage out of control, the overvoltage crowbar action, make the pwm circuit failure of oscillations, no longer exports driving pulse, and power converter just stops transformation, and power supply is no longer exported.And then the protection consumer is not by the damage of high output voltage.Once the overvoltage protection action, power module must be overhauled.More than be called the AC-DC conversion, also have a road output in this conversion, it is superimposed upon in main output, that is to say that its negative pole connects the positive pole of main output, its cathode voltage is exactly main piezoelectric voltage+superimposed voltage, and the voltage after this stack, as the final voltage in charging road, is supplied with charge circuit and used.Reduced the winding coil in the switch transformer on its advantage, volume of transformer is diminished, superimposed voltage is secondary output, it is fluctuateed by the impact of output load to some extent, because the number of turn of stack is few, so the impact of acceptor's output also reduces, greatly improve the stability of charging voltage.
When having reserve battery correctly to access, standby piezoelectric voltage sampled signal is sent into sample processing unit, when under the standby normal condition of piezoelectric voltage, main electricity is worked, it is just the reserve battery charging, if main electricity is not opened, only opened standby electricity, clicked standby eletric starter button, standby electricity just accesses power module, at this moment the DC-DC circuit working of next stage, produce rear three road output voltages.Now low level " AC " signal output, control demonstration for the user.
When standby piezoelectric voltage drops to standby electric under-voltage set-point when following, the output of " BT-LV " low level signal is arranged, and audible alarm is arranged.The standby electricity that continues to be reduced to setting when standby piezoelectric voltage closes breakpoint when following, stops all Voltage-outputs, and to maintain audible alarm be more than one hour, during reporting to the police, if main electricity input recovers normal, reports to the police and stops, and gets back to charged state.Now three status signals are high level.
The DC-DC circuit, take typical 5V as main output, and the 5V of it and another low pressure isolates mutually, for the power supply of control panel require degree of stability high, so input as power supply with main output.Low-voltage output circuit impact on change-over circuit when overcurrent is less, thus specially low-voltage circuit is carried out to current sampling, once electric current surpasses measured value; the current-limiting circuit action; make the DC-DC circuit enter guard mode, after overload is cancelled, then recover normal operating conditions.
The supply voltage of the PWM chip of DC-DC circuit is taken from outputting inductance; once Third Road output overloading or overcurrent are arranged; the main electricity output of low pressure and the overcurrent protection action of the secondary output of low pressure; output voltage reduces; the coupled voltages of power supply coil also reduces; when being not enough to maintain the PWM chip operation; output stops; enter guard mode; only have starting resistance again to make the oscillatory circuit of chip rework and could again be judged whether above-mentioned overload situations exists; if problem does not solve, enter again guard mode.Until shutdown or overload are cancelled.
The utility model is based on that the circuit block diagram of practical application set forth.For the technician in fire-fighting power supply field, according to the utility model scheme, by same thinking and power supply control technology that similarly component placement is developed, be all protection domain of the present utility model.
