[0002] Emergency evacuation lamps are lamps used to guide people to evacuate in an emergency. They are usually installed in public places, buildings, factories, etc. Emergency evacuation lamps can be powered by batteries or external power supplies to provide lighting in power outages or other emergencies to help people evacuate quickly.

[0003] In order to simplify the system structure, reduce costs, and facilitate the installation and maintenance of lamps, emergency evacuation lamps usually adopt a design in which the power supply and controller are separated. That is, the lamp itself is powered by a built-in battery, and the controller is connected to the lamp via a cable to control the lamp.

[0004] Since the entire system relies on the work of the central controller, when the central controller fails, the functions of the entire system will not work properly, resulting in the evacuation lamps not being accurately controlled. In addition, its functions are relatively single and it is unable to monitor the status of the power supply and battery in real time, resulting in the failure of the power supply and battery to be reported in time, requiring manual irregular inspections, which increases the workload.

To this end, the utility model proposes an emergency evacuation lamp centralized control system, which solves the problem that the evacuation lamp cannot be accurately controlled when the controller fails, and the power supply and battery status cannot be monitored in real time, resulting in the failure to report the fault in time.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

In the utility model, the 220VAC mains power input from the power grid is conveniently converted into 36V DC through the AC-DC switching power converter module, and the output 36V DC is used to supply power to the load. The data acquisition module is used to not only conveniently collect the output voltage and output current of the main supply line, but also to conveniently monitor the battery voltage and charging current data of the battery pack in real time. In addition, when the data acquisition module does not collect the input AC voltage, it cooperates with the main and standby power switching module and the single-chip microcomputer MCU to conveniently send a switch S1 closing signal, so that the battery pack supplies power to the load. The battery charge and discharge management module and the single-chip microcomputer MCU are used to conveniently automatically control the switch S2, which is not only convenient to control whether to charge the battery pack, but also can control the charging current, floating charge voltage and limit discharge voltage, thereby realizing the digital management of charging and discharging of the standby battery pack.

[0014] 2.

[0018] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1 As shown, an emergency evacuation lighting centralized control system includes an AC-DC switching power converter module 1, a load 2 and a battery pack 3. In this embodiment, the load 2 includes a safety indicator light, an alarm, etc. The load 2 and the AC-DC switching power converter module 1 are connected with a main supply line. The AC-DC switching power converter module 1 is used to convert the 220VAC mains power input from the power grid into DC 36V, and the output DC 36V supplies power to the load 2. A backup line is connected between the main supply line and the battery pack 3, and a switch S1 is installed on the backup line. Whether the battery pack 3 is enabled is controlled by controlling whether the switch S1 is closed.

[0020] A battery charge and discharge management module 4 and a data acquisition module 5 are electrically connected to the main supply line. The data acquisition module 5 is used to conveniently collect the output voltage and output current of the main supply line. The data acquisition module 5 is electrically connected to a main-standby power switching module 6. The main-standby power switching module 6 is electrically connected to a single-chip microcomputer MCU7 for controlling the switch S1. When the data acquisition module 4 fails to collect the input AC voltage, the single-chip microcomputer MCU7 gives a switch S1 closing signal, so that the battery group 3 can supply power to the load 2 when the power grid is cut off.

[0021] A switch S2 is installed on the circuit between the battery charge and discharge management module 4 and the battery pack 3. The battery charge and discharge management module 4 is used to detect whether the battery pack 3 is fully charged. If it is not fully charged, the single-chip microcomputer MCU7 is used to give a closing signal to the switch S2 to charge it. After the battery is fully charged, the switch S2 is disconnected to avoid overcharging of the battery pack 3. In addition, the battery charge and discharge management module 4 can control the charging current, floating charge voltage and limit discharge voltage to realize digital management of charging and discharging of the backup battery pack 3.

[0022] The data acquisition module 5 is electrically connected to the battery pack 3 and the single-chip microcomputer MCU7 through wires, respectively, so as to facilitate real-time monitoring of data information such as the battery voltage and charging current of the battery pack 3. The AC-DC switching power converter module 1 is electrically connected to a fault detection module 9, which is electrically connected to the single-chip microcomputer MCU7. The fault detection module 9 is electrically connected to the data acquisition module 5, and the fault detection module 9 is electrically connected to the main power supply line, so as to facilitate the collection of the status of the mains and the battery pack 3, so that the information can be collected in time after a fault occurs.

[0023] The single-chip microcomputer MCU7 is communicatively connected to a host computer monitoring display 8, and the single-chip microcomputer MCU7 is electrically connected to a communication module 10. The communication module 10 includes an isolation 232 communication module, which can reduce signal attenuation and distortion and improve communication stability and reliability. The single-chip microcomputer MCU7 is communicatively connected to the host computer monitoring display 8 through the communication module 10, so that the fault information collected by the fault detection module 9 and the data information collected by the data acquisition module 5 are conveniently transmitted to the host computer monitoring display 8, so that the battery fault of the power supply and the battery pack 3 can be reported immediately without manual inspection, thereby reducing the workload.

[0024] The single-chip microcomputer MCU7 is electrically connected to a forced emergency function module 11, which is electrically connected to the data acquisition module 5, and the forced emergency function module 11 is provided with an external button, which is used to control the single-chip microcomputer MCU7 to issue an emergency function command to cut off the power supply of the main supply line. For example, if the power grid is not powered off in time during a fire, if the load 2 is still powered by the power grid, the wires may be damaged or overloaded under the fire state, causing the power supply line to overheat or burn, which may cause electrical accidents such as wire short circuits, increasing the risk of fire. The button of the forced emergency function module 11 is used to facilitate the single-chip microcomputer MCU7 to issue an emergency function command to cut off the power supply of the main supply line, so that in a fire emergency state, only the battery pack 3 can be used for power supply.

[0025] The working principle of the utility model is as follows: the 220VAC mains power input from the power grid is converted into 36V DC by using the AC-DC switching power converter module 1, and the output 36V DC is used to power the load 2. The output voltage and output current of the main supply line can be collected by using the data acquisition module 5. When the AC voltage input from the main supply line is not collected, the single-chip microcomputer MCU7 gives a switch S1 closing signal, so that the battery pack 3 can supply power to the load 2 when the power grid is cut off. The battery charge and discharge management module 4 is used to detect whether the battery pack 3 is fully charged. If it is not fully charged, the single-chip microcomputer MCU7 gives a switch S1 closing signal. The S2 closing signal enables it to charge, and the switch S2 is disconnected after the power is fully charged to prevent the battery pack 3 from being overcharged. The communication module 10 can be used to transmit the fault information collected by the fault detection module 9 and the data information collected by the data acquisition module 5 to the upper computer monitoring display 8, so that the battery failure of the power supply and the battery pack 3 can be reported immediately without manual inspection. When a fire emergency occurs, pressing the external button of the forced emergency function module 11 can cut off the power supply of the main supply line, so that in the fire emergency state, only the battery pack 3 can be used for power supply, thereby avoiding electrical accidents such as short circuits in wires and increasing the risk of fire.

[0026] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
