Abstract
The utility model discloses a fire-fighting linkage power supply module characterized by comprising a main electric input unit, an EMC circuit connected with the main electric input module, a PMW control unit connected with the EMC circuit, a transition circuit, a charging circuit and a processing and control unit connected with the PWM control unit, and a standby electric input unit connected with the charging circuit; the standby electric input unit is connected with the transition circuit; the transition circuit is connected with a display device. Line failure problem of the output line is more comprehensively solved, and uninterrupted power supply problem is better solved, so fire-fighting control equipment can maximally use the standby battery pack to ensure effective operation of the fire-fighting equipment in a condition without AC power supply.
Description
Technical field
The utility model belongs to the fire-fighting power supply technical field, particularly a kind of fire-fighting link power module.
Background technology
Usually the power supply wiring in the fire-fighting distribution box is numerous and diverse, and serious interference is unfavorable for the control of EMC index.And, because operating current is usually all very large, the lead-in wire of external terminal also can produce corresponding line and decline, and causes last lower voltage.Active and standby electric translation function is limited by sample circuit in addition, causes individual difference and temperature contrast that very large discreteness is arranged, some power supplys do not realize at all active and standby electricity continuously every switching.Also because different user controls, different with the requirement of demonstration aspect each is variant in the requirement of output signal in addition.
The utility model content
The technical problem that the utility model solves is to provide a kind of fire-fighting link power module, the line that the solves outlet line problem that declines comparatively perfectly, solved better the problem of uninterrupted power supply, make the fire-fighting control appliance bring into play to a greater degree without under the Alternating Current Power Supply condition by battery backup, ensure effective operation of fire-fighting equipment.
For solving above technical problem, the utility model by the following technical solutions, a kind of fire-fighting link power module, is characterized in that, comprises main electric input unit, the EMC circuit be connected with described main electric input module, the PMW control unit be connected with the EMC circuit, the change-over circuit, charging circuit and the processing and control element (PCE) that with the PMW control unit, are connected, the standby electric input unit be connected with charging circuit, standby electric input unit connects change-over circuit, and change-over circuit connects display unit.
Described main electric input unit comprises main electric input circuit, the main electric sample circuit be connected with main electric input circuit, described main electric input circuit connects the EMC circuit, the autonomous electric input circuit of described main electric sample circuit sampling, after described main electric sample circuit sampling, signal is transferred to described processing and control element (PCE), described main electric sample circuit connects main electric undervoltage warning circuit.
Described standby electric input unit comprises standby electric input circuit, and standby electric input circuit connects change-over circuit, and standby electric input circuit connects charging circuit, and standby electric input circuit connects standby electric sample circuit, and standby electric sample circuit connects standby electric undervoltage warning circuit.
Good effect of the present utility model is:
1. directly being connected on circuit board at output line has on lead-out terminal, has reduced the line that internal connection line causes and has declined and disturb, and makes the output-index reflect more realistically the actual output voltage ability of power supply;
2. the transfer process that really realizes active and standby electricity does not produce voltage and falls phenomenon, meets the national standard requirement of fire-fighting equipment;
3. signal output state flexibly, be applicable to the requirement of user's display panel better;
4. the startup of stand-by power supply and shutoff arrange flexibly by control unit, guarantee very exactly normal demonstration and the switching of each working point.
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, main electric sample circuit samples autonomous electrical input, before the EMC filter, send into processing and control element (PCE) after sampling, when electric circuit inspection too low or while not having to input voltage, to send and be transformed into standby electricity work order, and make power supply proceed to standby electric work state, export main electric fault alarm signal to display panel simultaneously.Standby electric input circuit is also sent the voltage signal of sampling into processing and control element (PCE), be sent to again change-over circuit simultaneously, after being transformed into standby electricity work order arrival, by on standby circuit on output switching, main electricity no longer outputs to load simultaneously, when standby piezoelectric voltage being detected when under-voltage, turn off standby electricity output, revert to main electric work state, if now main electricity can not provide output, power supply enters off-mode.Under main electricity and the equal normal condition of standby electricity, standby electricity does not participate in output, for standby battery, is charged simultaneously.Another key point of this novel practical technology is exactly that the standby electricity of the switch between alternating current and standby battery circuit is while transferring main electricity work to, do not produce the power down phenomenon, the voltage detecting of main electricity output is taken from output, control output detections voltage not higher than main electric output valve, main electricity work circuit just not there will be the misoperation of the main electricity output of sealing.Overvoltage crowbar and current foldback circuit are the standing functions of Switching Power Supply, do not make specified otherwise here.But output voltage shows and the output current demonstration is but specially to be designed to the demonstration of particular panel and corrected.When output voltage is too low, just there is main electric fault alarm signal to output on display panel.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, the relevant staff can, in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to the claim scope.
