A fire fault protection method for an energy management system

Abstract

This invention discloses a fire fault protection method for an energy management system. The energy management system includes a fire control module, which receives detection data from a detection module. Based on the fire alarm information triggered by the detection data, the control module powers on a backup battery, which then supplies power to the energy management system. If the fire alarm information is a fire-linkage alarm, the energy management system activates the sprinkler system. After successful spraying, the energy management system de-energizes the backup battery. This method avoids abnormal data reception in the energy management system due to hardware failure of the independent fire control unit. Furthermore, when the fire alarm information is a fire-linkage alarm, the energy management system actively disconnects the backup battery by activating the sprinkler system and de-energizing it after successful spraying, thus extending the power supply's lifespan.

Description

[0001] This case is a divisional application based on the invention patent filed on May 16, 2024, with application number 202410605509.2 and title "A Fire Protection System and Fire Fault Protection Method". Technical Field

[0002] This invention relates to the technical field of fire protection failure protection, and in particular to a fire protection failure protection method for an energy management system. Background Technology

[0003] Existing fire suppression systems in energy storage systems typically employ a separate fire suppression control panel, which facilitates communication between combustible gas detectors and the EMS (Energy Management System). Please refer to... Figure 1 In the event of a fire alarm, the combustible gas detector, i.e. the carbon monoxide detector, sends information to the fire alarm control panel. The control panel is responsible for spraying and other actions and processes the information before sending it to the EMS system. When the EMS system detects a fault, it takes appropriate protective measures.

[0004] However, the current method of gas detectors communicating with dry contacts and connecting to the fire alarm control panel, with the control panel processing the data and then feeding the results back to the EMS system, has the following problems:

[0005] ① High failure rate. If the fire alarm control panel malfunctions, the fire alarm information data received by the EMS system will also be abnormal.

[0006] ② The lifespan of the backup battery is reduced. Please refer to... Figure 2 All components in the energy storage device share a single UPS (Uninterruptible Power Supply) for power supply, while the fire control panel within the device is equipped with its own backup battery. When a fault is triggered, the fire control panel switches to its backup battery for power and completes the fire spraying operation; if the main power supply is disconnected due to a fault, the backup battery of the fire control panel will start supplying power until its charge is depleted and then disconnect. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a fire fault protection method for an energy management system, which can reduce the occurrence of faults in the fire control process and extend the service life of the fire backup power supply.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0009] A fire protection system includes a detection module, an energy management system, a fire protection main control module, and a power supply module;

[0010] The detection module is communicatively connected to the fire control module;

[0011] The fire protection main control module is integrated into the energy management system;

[0012] The power module includes a backup battery, which supplies power to the energy management system and the fire control module. The power module is an uninterruptible power supply.

[0013] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is as follows:

[0014] A fire protection fault protection method, applied to the above-mentioned fire protection system, includes the following steps:

[0015] The fire control module receives detection data sent by the detection module, cuts off preset non-critical equipment based on the fire alarm information triggered by the detection data, and powers on the backup battery.

[0016] The energy management system obtains the detection data and fire alarm information through the integrated fire control module;

[0017] If the fire alarm information is a fire alarm information, the fire main control module detects the fire alarm situation and puts the energy storage device corresponding to the fire protection system into standby mode;

[0018] If the fire alarm information is a fire-fighting linkage information, the energy management system will start the spraying device. After successful spraying, the energy management system will control the backup battery to shut down.

[0019] The beneficial effects of this invention are as follows: The fire control module is integrated into the energy management system. The fire control module can directly receive detection data, and as a functional module of the energy management system, the energy management system can also directly receive detection data. After the fire control module receives the detection data and triggers a fire alarm based on it, it cuts off preset non-critical equipment and powers on the backup battery. This avoids abnormal data reception by the energy management system due to hardware failure of the independent fire control unit; and proactively cutting off non-critical equipment based on the fire alarm increases the backup power duration of the power module. Furthermore, when the fire alarm is a fire alarm, the fire control module detects the fire situation; when the fire alarm is a fire linkage information, the energy management system starts the sprinkler system. After successful spraying, it powers off the backup battery, proactively cutting off the backup battery and extending the power supply's lifespan. Attached Figure Description

[0026] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0027] Please refer to Figure 3 This invention provides a fire protection system, including a detection module, an energy management system, a fire protection main control module, and a power supply module.

[0028] The detection module is communicatively connected to the fire control module;

[0029] The fire protection main control module is integrated into the energy management system;

[0030] The power module includes a backup battery, which supplies power to the energy management system and the fire control module. The power module is an uninterruptible power supply.

[0031] As described above, the beneficial effects of this invention are as follows: The fire control module is integrated into the energy management system. The fire control module can directly receive detection data, and as a functional module of the energy management system, the energy management system can also directly receive detection data. After the fire control module receives the detection data and triggers a fire alarm based on it, it cuts off preset non-critical equipment and powers on the backup battery. This avoids abnormal data reception by the energy management system due to hardware failure of the independent fire control unit; and proactively cutting off non-critical equipment based on the fire alarm increases the backup power duration of the power module. Furthermore, when the fire alarm is a fire alarm, the fire control module detects the fire situation; when the fire alarm is a fire linkage information, the energy management system starts the sprinkler system. After successful spraying, it powers off the backup battery, proactively cutting off the backup battery and extending the power supply's lifespan.

[0032] Furthermore, the power module also includes a transformer, the input end of which is connected to the backup battery, and the output end of which is connected to the energy management system and the fire control module.

[0033] As described above, the voltage of the backup battery is adjusted by a transformer so that the adjusted voltage can be adapted to important equipment such as the energy management system and the fire control module, thus ensuring the effectiveness of the backup battery power supply.

[0034] Furthermore, it also includes a rectifier, and the fire protection system also includes pre-installed non-critical equipment;

[0035] The pre-defined non-critical equipment is connected between the rectifier and the transformer;

[0036] The rectifier is connected to the power grid.

[0037] As described above, the main power supply for non-critical equipment, energy management system and fire control module is provided by the power grid, and the non-critical equipment is connected between the rectifier and transformer to facilitate disconnection or reconnection of the non-critical equipment according to the actual situation.

[0038] Furthermore, the detection module includes a smoke detector, a carbon monoxide detector dry contact, and a temperature detector;

[0039] The smoke detector and the heat detector are communicatively connected to the fire control module.

[0040] The carbon monoxide detector is connected to the fire control module via a dry contact.

[0041] As described above, smoke and heat detectors are connected to the fire control module in the energy management system, and carbon monoxide detectors are connected to the fire control module in the energy management system via dry contacts. Since the fire control module is integrated into the energy management system, it has become a functional module of the energy management system. This can prevent the energy management system from receiving abnormal data due to hardware failure of the independent fire control module, thus reducing the probability of failure.

[0042] Please refer to Figure 5 Another embodiment of the present invention provides a fire protection fault protection method, applied to the above-mentioned fire protection system, comprising the following steps:

[0043] The fire control module receives detection data sent by the detection module, cuts off preset non-critical equipment based on the fire alarm information triggered by the detection data, and powers on the backup battery.

[0044] The energy management system obtains the detection data and fire alarm information through the integrated fire control module;

[0045] If the fire alarm information is a fire alarm information, the fire main control module detects the fire alarm situation and puts the energy storage device corresponding to the fire protection system into standby mode;

[0046] If the fire alarm information is a fire-fighting linkage information, the energy management system will start the spraying device. After successful spraying, the energy management system will control the backup battery to shut down.

[0047] As described above, the beneficial effects of this invention are as follows: The fire control module is integrated into the energy management system. The fire control module can directly receive detection data, and as a functional module of the energy management system, the energy management system can also directly receive detection data. After the fire control module receives the detection data and triggers a fire alarm based on it, it cuts off preset non-critical equipment and powers on the backup battery. This avoids abnormal data reception by the energy management system due to hardware failure of the independent fire control unit; and proactively cutting off non-critical equipment based on the fire alarm increases the backup power duration of the power module. Furthermore, when the fire alarm is a fire alarm, the fire control module detects the fire situation; when the fire alarm is a fire linkage information, the energy management system starts the sprinkler system. After successful spraying, it powers off the backup battery, proactively cutting off the backup battery and extending the power supply's lifespan.

[0048] Furthermore, the fire control module receives detection data sent by the detection module, including:

[0049] The fire control module receives smoke data from smoke detectors via communication connections, temperature data from heat detectors via communication connections, and cylinder status data from carbon monoxide detectors via dry contact connections.

[0050] As described above, smoke and heat detectors are connected to the fire control module in the energy management system, and carbon monoxide detectors are connected to the fire control module in the energy management system via dry contacts. Since the fire control module is integrated into the energy management system, it has become a functional module of the energy management system. This can prevent the energy management system from receiving abnormal data due to hardware failure of the independent fire control module, thus reducing the probability of failure.

[0051] Furthermore, the energy management system activates the spraying device, and upon successful spraying, the energy management system controls the backup battery to shut down, including:

[0052] The energy management system starts the spraying device and receives the cylinder status of the spraying device detected by the detection module. If the cylinder status indicates that spraying has been completed, the energy management system controls the backup battery in the power module to power off. Otherwise, the energy management system continues to control the spraying device to spray.

[0053] As described above, the system determines whether the spraying has been successfully started based on the status feedback of the fire cylinder. Once the spraying is successful, the control power module is powered down, which can actively disconnect the backup battery and extend the service life of the power supply.

[0054] This invention is applicable to reducing the occurrence of faults in fire control processes and extending the service life of fire backup power supplies. The following specific embodiments illustrate this:

[0055] Example 1

[0056] Please refer to Figure 3 and Figure 4 A fire protection system, comprising a detection module, an energy management system, a fire control module, and a power supply module;

[0057] The fire control module is integrated into the energy management system, and the detection module is communicatively connected to the fire control module. In this embodiment, the detection module includes a smoke detector, a carbon monoxide detector dry contact, and a heat detector. The smoke detector and heat detector are communicatively connected to the fire control module, and the carbon monoxide detector is connected to the fire control module via a dry contact.

[0058] The power module is an uninterruptible power supply (UPS), which includes a backup battery and a DC / DC transformer. The fire protection system also includes an AC / DC rectifier. Specifically, the power grid, AC / DC rectifier, and DC / DC transformer are connected sequentially. In this embodiment, the energy storage power supply load is divided into critical and non-critical equipment. Critical equipment includes the fire protection main control module and the energy management system, while the backup battery only powers the critical equipment. Therefore, the input terminal of the DC / DC transformer is connected to the backup battery, and the output terminal is connected to the critical equipment; non-critical equipment is located between the AC / DC rectifier and the DC / DC transformer.

[0059] Example 2

[0060] Please refer to Figure 5 and Figure 6 A fire protection fault protection method, applied to a fire protection system according to Embodiment 1, includes the following steps:

[0061] S1. The fire control module receives the detection data sent by the detection module, cuts off the preset non-critical equipment according to the fire alarm information triggered by the detection data, and powers on the backup battery.

[0062] The energy management system obtains the detection data and fire alarm information through the integrated fire control module.

[0063] Specifically, the fire control module receives smoke data from smoke detectors via a communication connection, temperature data from heat detectors via a communication connection, and cylinder status data from carbon monoxide detectors via a dry contact connection.

[0064] S2. If the fire alarm information is a fire alarm information, the fire main control module detects the fire alarm situation and puts the energy storage device corresponding to the fire protection system into standby mode.

[0065] S3. If the fire alarm information is a fire linkage information, the energy management system starts the spraying device. After the spraying is successful, the energy management system controls the backup battery to shut down.

[0066] Specifically, the energy management system starts the spraying device and receives the cylinder status of the spraying device detected by the detection module. If the cylinder status indicates that spraying has been completed, the energy management system controls the backup battery in the power module to power off. Otherwise, the energy management system continues to control the spraying device to spray.

[0067] In summary, this invention integrates the fire control module into the energy management system. The fire control module can directly receive detection data, and as a functional module of the energy management system, the energy management system can also directly receive detection data. After the fire control module receives detection data and triggers a fire alarm based on it, it cuts off preset non-critical equipment and powers on the backup battery. This avoids abnormal data reception by the energy management system due to hardware failure of the independent fire control unit; and proactively cutting off non-critical equipment based on fire alarm information increases the backup power duration of the power module. Furthermore, when the fire alarm information is a fire alarm, the fire control module detects the fire situation; when the fire alarm information is a fire linkage information, the energy management system activates the sprinkler system. After successful spraying, it powers off the backup battery, proactively cutting off the backup battery and extending the power supply's lifespan.
