Likewise, the invention provides four embodiments for realizing circuit switching for the light source power supply switching circuit.

Furthermore, the present invention can also realize control of the illumination unit at the power supply control portion, for example: the control button 2 receives a third operation, the main control processor 1 sends out a third signal, the single control processor 4 detects the internal power supply 6 of each lighting unit according to the third signal, for the internal power supply 6 with a normal detection result, the single control processor power supply switching circuit and the light source power supply switching circuit control the corresponding light source 5 to be normally lighted, and for the internal power supply 6 with an abnormal detection result, the single control processor power supply switching circuit and the light source power supply switching circuit control the corresponding light source 5 to be not lighted or twinkle to give out light.

In the above structural design, the present invention realizes the switching of the power supply mode between the power supply module and the battery module by the single control processor 4 according to whether the power supply control part (power supply module) supplies power. In this embodiment, different from the above switching manner, the present invention further provides a signal line disposed in parallel with the electric wire 3, the signal line is connected to the main control processor 1 and each single control processor 4, the main control processor 1 can send a control signal to each single control processor 4 through the signal line, so that the main control processor 1 can directly send the control signal to the single control processor 4, and then the single control processor 4 performs switching of the power supply mode locally (in the lighting unit).

Specifically, the invention further comprises a wire connecting plug for connecting with the wire 3, the wire connecting plug and the main control processor 1 are in three-pin connection (namely, a three-pin or pin structure), two pins are used for transmitting electric energy, and the third pin is used for detecting the connection state between the wire connecting plug and the wire.

The power supply assembly further comprises a power plug, a power adapter is connected with the power plug, a charging unit is connected with the power adapter, a rechargeable standby power supply is connected with the charging unit, and the standby power supply is connected with the main control processor 1 through a low-voltage-difference linear voltage stabilizer.

In the present invention, the lighting unit is disposed on the electric wire 3 and forms the light-emitting electric wire 3 together with the electric wire 3, and the outer side of the light-emitting electric wire 3 is wrapped with a transparent wire casing, which should satisfy two conditions, the first condition is that the wire casing should be made of a transparent material or a material having a certain color but being light-permeable, and the second condition is that the wire casing has a certain strength and high temperature resistance.

Specifically, in the use, electric wire 3 can be earlier adopted the mode of dragging by the fire fighter and is being pulled and get into the rescue place, and if electric wire 3 lay length longer, then the pulling force (pulling force) that electric wire 3 received will be bigger, in order to avoid electric wire 3 to be pulled apart, preferably, has set up the intensity enhancement line in the wire rod casing, and the intensity enhancement line is the wire, through setting up the intensity enhancement line, can improve electric wire 3's intensity in order to bear great pulling force.

Through the structural design, the plurality of groups of lighting units are arranged on the electric wire 3, each group of lighting units is independently provided with the single control processor 4 and is provided with the internal power supply 6 capable of independently providing electric energy, the single control processor 4 can realize power supply switching according to whether the power supply control part provides the electric energy, and therefore even if the electric energy supply of the power supply control part is lost (for example, the electric wire 3 is cut off and the like), the disconnected electric wire 3 part can be automatically lightened, and lighting guide is provided for firemen.

The invention provides a fire-fighting and life-saving illuminating line which comprises a power supply control part and an illuminating line body part, wherein the illuminating line body part is connected with the power supply control part through an electric wire connecting plug and an electric wire. The lighting line body part mainly comprises two lengthways electric wires 3, a plurality of groups of lighting units are arranged on the electric wires 3, and each lighting unit comprises a small MCU (single control processor 4), a battery, an LED, voltage conversion and an LED drive.

In the lighting unit, the battery can be a disposable battery, such as a button battery, and also can be a rechargeable battery, the LED can be one lamp bead, or can be a plurality of lamp beads, the whole electric wire 3 and all the lighting units are wrapped with a transparent material together at the periphery, the transparent material has corresponding strength and toughness, and can support the pulling of the ordinary adult under the general use condition, if the electric wire 3 is thinner, an iron wire or other metal wires can be additionally added to increase the strength, and all the elements adopt high-temperature resistant elements to meet the high-temperature resistant requirement.

The power control part comprises a large MCU (main control processor 1), a power adapter, a wire 3 driving module, an LDO (low dropout regulator), a switch and the like, when an external power supply (such as a wall power supply) is plugged, the external power supply supplies power to the main control processor 1 (large MCU) through the LDO via the power adapter, when the switch is pressed down, the main control processor 1 receives a switch signal and sends a first power control signal to control the wire 3 driving module to send a first power signal, the small MCU (single control processor 4) receives the first power signal and starts working, the LED is powered by the first power signal, a battery is not powered, and the power supply mode is a general use mode. In the normal use mode, if the single control processor 4 suddenly does not receive the first power signal, such as a power-off condition, the single control processor 4 switches to a mode for powering the LEDs using the battery. When the switch is pressed again, the main control processor 1 receives a second power supply control signal sent by the switch signal and controls the electric wire 3 to drive the module to send a second power supply signal, the single control processor 4 receives the second power supply signal, the first power supply signal is cut off, power is not supplied to the LED any more, at the moment, the battery does not supply power, and the LED is turned off, so that the LED enters a turn-off mode.

In the off mode, single control processor 4 continuously detects whether the first power signal, the second power signal, and no power signal are received. Of course, in the off mode, the battery does not power the LEDs even if the external power source is not plugged in.

In order to realize that the external power supply and the battery do not supply power in the off mode, and the battery is switched to supply power to the LED when the external power supply is preferentially used for supplying power in the use mode and the power is suddenly cut off, the invention mainly has two key points, wherein the power is switched to supply power to the single control processor 4, and the other one is switched to supply power to the LED.

The specific implementation modes are as follows:

first, the first power signal and the second power signal are both input to the voltage conversion module, the battery is directly and only connected with the power input end of the single control processor 4 through one diode respectively, when an external power supply exists, the voltage of the external power supply converted by the voltage conversion module is larger than the voltage of the battery, and the external power supply supplies power to the single control processor 4. When there is no external power supply, the output voltage of the voltage conversion module (voltage zero) is less than the battery voltage, and the battery supplies power to the single control processor 4.

Secondly, in order to avoid energy waste caused by static power consumption (in the off mode, in the first mode, the battery actually supplies power to the single control processor 4 all the time), the present invention is based on the first mode, in which a capacitor is disposed on the power input terminal of the single control processor 4, and meanwhile, the battery is connected to the power input terminal of the single control processor 4 by a MOS transistor instead, and the single control processor 4 can also generate a control signal to the MOS transistor. So, under the shutdown mode, also be in the off-state between battery and the single control processor 4, when being in external power supply under the user mode, the electric capacity stores a small amount of electric quantity simultaneously, when the outage suddenly, single control processor 4 uses the electric quantity work of electric capacity, and output control signal makes MOS pipe switch on for the MOS pipe, and the battery supplies power for single control processor 4 this moment, and then control battery is for LED power supply. When the battery is normally closed, the single control processor 4 outputs a control signal according to the second power signal to disconnect the MOS transistor, so that the battery and the single control processor 4 are in a disconnected state and enter a closed mode.

It should be noted that, in the use mode, if the external power supply is suddenly powered off, the MOS transistor is turned on, and the battery supplies power to the single control processor 4; and then, if the external power supply suddenly comes on (for example, the power off is suddenly cut off by pulling out the power supply to perform the simulation test in the daily training process, and then the power supply is plugged in), at this time, because the battery and the single-control processor 4 are already in the connected state, the external power supply is also connected to the single-control processor 4, and a posture for charging the battery is formed at the same time. If the battery is a normal non-rechargeable battery, the working mode for charging the battery is dangerous for the normal non-rechargeable battery, so that the single control processor 4 has to output a control signal to disconnect the MOS transistor when receiving an external power supply, so as to ensure safety.

The first mode and the second mode are both switched to supply power to the single control processor 4, and the third mode, the fourth mode and the fifth mode are switched to supply power to the LED.

Firstly, the scheme of the MOS transistor is adopted, which is similar to the structure of the second mode (similar to the MOS transistor described in the second mode), and a MOS transistor is arranged between the external power supply (voltage conversion module) and the LED driver, and a MOS transistor is also arranged between the battery and the LED driver. When the MOS transistor is turned off (at the moment, an external power supply supplies power), the single control processor 4 outputs a control signal to enable the two MOS transistors to be turned off and enter a turn-off mode. When the LED lamp is used, the single control processor 4 receives a first power supply signal, outputs a control signal to enable the MOS tube between the external power supply and the LED drive to be conducted, the external power supply supplies power to the LED, if the power is suddenly cut off, the single control processor 4 detects that the external power supply disappears, outputs the control signal to enable the MOS tube between the battery and the LED drive to be conducted, and the battery supplies power to the LED. In the third mode, the single-control processor 4 continues to detect the external power supply (for example, by using a voltage detection method) after receiving the first power supply signal and starts to operate, and immediately performs the above operations when detecting that the external power supply disappears, and of course, simultaneously switches the power supply to the single-control processor 4 (the above two solutions are also used).

In the third mode described above, the MOS transistor can be directly replaced with a relay.

In the third mode, the MOS transistor can be replaced by a diode. The principle is similar to the first embodiment. It should be noted that, at this time, the single control processor 4 is not required to output the control signal, and the switching of the power supply to the LED is formed according to the voltage difference between the external power supply and the battery. And the modes three and four require the single control processor 4 to output control signals, so that the switching of the power supply to the LED can be formed. In the fifth mode, whether the LED lamp is on or off depends on the LED driving, and when the LED needs to be turned on, for example, the single control processor 4 receives the first power signal, and outputs a control signal to turn on the LED driving, so that the LED is turned on in cooperation with the switching of the power supply.

And sixthly, the LED drive is matched with the third mode, the fourth mode and the fifth mode to switch the power supply, and then the LED is lightened. Therefore, in the sixth mode, LED driving is a relatively complex control scheme. In the sixth mode, at least one switching circuit is included, which is controlled by the single-control processor 4 to be turned off when needed and turned on when needed. In addition, a ballast circuit or the like may be included (since the LED is a current driving element, the ballast circuit is generally required to be provided). It should be noted that: in the sixth mode, the LED driving may also be simplified, for example, a current-limiting resistor is provided, and the LED lamp may also be turned on only based on the power switching manner in the previous mode, but the lighting operation of the LED lamp is not stable at this time. Certainly, the fifth mode is no longer applicable, because the switching of the power supply is directly switched based on the difference between the two voltages as in the first scheme, when no external power supply exists, the battery is always supplying power to supply power to the LED lamp, and the LED lamp is always in an on state and cannot be turned off. The third mode and the fourth mode do not have the problem, and the power supply can be disconnected through a MOS tube or a relay when the power supply needs to be closed.

Seventhly, based on the second mode, in the second mode, when the external power supply is suddenly powered off, the single control processor 4 is enabled to continuously work through the capacitor, the battery is switched to supply power to the single control processor 4, and the single control processor 4 continuously works to supply power to the LED lamp through the battery and light the LED lamp. In this mode, the battery may not be continuously supplied to the single control processor 4 (i.e., there is no MOS transistor between the battery and the single control processor 4), and when the external power supply is suddenly turned off, the single control processor 4 is supplied with power by using the electric quantity of the capacitor, so that the single control processor 4 outputs a control signal, and the battery is switched to supply power. In the seventh mode, after the electric quantity of the capacitor is supplied to the single control processor 4, the single control processor 4 sends out a control signal, the electric quantity of the capacitor is exhausted (generally at most millisecond level), the single control processor 4 is powered off, and at this time, the output control signal of the single control processor 4 may be incomplete, that is, the single control processor 4 may not send out a complete signal (such as a high level) for supplying power to the battery, and may also have other signals (such as a low level), and at this time, the power supply may be switched again, and then the LED may not be turned on.

Eighthly, in the first mode, if a double-diode scheme is adopted, a double relay can be directly used for replacement. When there is an external power supply, the external power supply side switch is turned on, and when there is no external power supply, the battery side switch is turned on. And the switch is a mechanical switch, has no self voltage drop and has lower power consumption.

Considering that if the plug is accidentally dropped or manually and directly pulled out from the power control part during normal use, the single control processor 4 will switch the battery to supply power to the LED due to power failure until the power is exhausted, and this non-emergency battery power supply situation should be avoided as much as possible, so the plug and the power control part are butted by three pins (three pins), two of which are used for transmitting power, and the third pin is used for detecting whether the plug is normally plugged in the power control part, if accidentally dropped or manually and directly pulled out, the main control processor 1 can detect through the third pin and send out a prompt, such as displaying characters or sending out a sound, to the power control part (so the power control part is also provided with a display unit and a sound-producing unit), the plug is dropped, please plug in, turn off the power supply, so that the user can use the power control part in a prescribed manner, and (4) plugging on the power supply, pressing a switch key, and disconnecting the battery and the LED.

Similarly, if the wall power supply accidentally drops or is manually and directly removed in the using process, and the single-control processor 4 can switch the battery to supply power to the LED due to power failure according to the previous content, in order to avoid the situation that the battery supplies power under the non-emergency condition, the invention can also be additionally provided with a standby power supply in the power supply control part, when the wall power supply accidentally drops or is manually and directly removed, the main-control processor 1 supplies power to the main-control processor 1 through the standby power supply, the main-control processor 1 detects that the wall power supply accidentally drops or is manually and directly removed, and the power supply control part sends out a prompt, such as displaying characters or sending out a sound, that the plug drops, please plug in and turn off the power supply, so that a user can plug in and press a switch key to disconnect the battery and the LED according to the specified mode. Accordingly, the backup power source is preferably a rechargeable battery, and a charging unit is provided, by which the backup power source can be charged when plugged in to the wall power source.

Further, since the battery is naturally discharged even when it is left unused for a long period of time, it is necessary to constantly detect whether or not the battery has a sufficient amount of electricity. Therefore, the power control part of the invention is also provided with a battery detection key, when the battery detection key is pressed, the main control processor 1 sends a third power signal, the single control processor 4 receives the third power signal and detects the battery power (such as voltage detection), if the battery power meets the requirement, the LED is lightened, and if the battery power does not meet the requirement, the LED is not lightened or flickers.

Twelve, above, all are based on the scheme that only two wires 3 have no signal wire, the wires 3 transmit variable-frequency alternating current, the first power signal, the second power signal and the third power signal all have different frequencies, and the single-control processor 4 performs corresponding different operations by identifying the different frequencies (in the third mode, the voltage detection may be changed into frequency detection). Therefore, the lighting unit side in the above scheme is provided with a voltage conversion circuit to convert the alternating current.

Thirteen, in addition, the invention can also adopt the scheme of adding signal lines, at this time, the power control part outputs direct current which is transmitted on the electric wire 3, and the single control processor 4 can directly start to work and supply power to the LED. The signal wire is used for transmitting different control signals corresponding to the switch key and the battery detection key, and the single control processor 4 carries out corresponding operation according to the different control signals.
