Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of alarm systems, and in particular to an addressing-to-non-addressing device and an alarm system. Background Art

[0002] In the related technology, the addressing system requires data transmission between the addressing host and the addressing node through the protocol. For example, fault information, fire alarm information, etc. all need corresponding protocol support. When the addressing node detects the alarm information, the alarm event code is reported to the addressing host. The addressing host receives the alarm event code and issues an alarm information prompt. The non-addressing host does not need protocol data transmission. The non-addressing host generally determines the alarm and line fault information by detecting the current change in the loop. For example, when the line is normal, when the non-addressing node detects the alarm, the non-addressing node will pull a specified larger current. The non-addressing host detects that the loop current reaches the current threshold for detecting the alarm, and the non-addressing host issues an alarm prompt. However, in order to reduce costs or due to different project requirements, the need for non-addressing nodes to be equipped with addressing hosts has emerged. However, non-addressing nodes do not support protocol transmission, and non-addressing nodes cannot be directly connected to the addressing host.

[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and in combination with the embodiments.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0028] In this embodiment, a device for converting addressing to non-addressing is provided. Figure 1 is a structural diagram of an addressing-to-non-addressing device according to an embodiment of the present invention, such as Figure 1 As shown, the addressing-to-non-addressing device comprises:

[0029] A non-addressed node status monitoring module 12, wherein the non-addressed node status monitoring module is connected to the non-addressed node and is used to monitor the voltage in the loop where the non-addressed node is located. The non-addressed node is a node that does not support protocol data transmission and is used to detect environmental parameters of a target area. When the environmental parameters are abnormal, the non-addressed node is in an alarm state, so that the voltage in the loop where the non-addressed node is located changes;

[0030] A controller 14, wherein the controller is connected to the non-addressed node status monitoring module, and the controller is also configured to be connected to an addressed host, for receiving a voltage detected by the non-addressed node status monitoring module, and determining fault information based on the voltage, and sending the fault information to the addressed host to instruct the addressed host to determine an alarm state based on the fault information.

[0031] In the above embodiment, the addressable host can be an alarm control panel, which can be a host that can communicate with the addressable node. The addressable node can be a sensor with a processor, which can communicate with the addressable node in real time. The non-addressable node can be regarded as an alarm switch. The non-addressable host does not need protocol data transmission. The non-addressable host generally determines the fire alarm and line fault information by detecting the current change in the loop. For example, when the line is normal, when the non-addressable node detects a fire alarm, the non-addressable node will pull a specified larger current. The non-addressable host detects that the loop current reaches the current threshold for detecting the fire alarm, and the non-addressable host issues a fire alarm prompt.

[0032] In the above embodiment, the non-addressed node status monitoring module can be connected to multiple non-addressed nodes, and multiple non-addressed nodes are connected in parallel. When there is a fault in the circuit where the non-addressed node is located, or the environmental parameters detected by the non-addressed node are abnormal, there will be a voltage abnormality in the circuit where the non-addressed node is located. The non-addressed node status monitoring module can detect the voltage and send the voltage to the controller. The controller can determine the fault information according to the voltage and send the fault information to the addressing host. The addressing host alarms according to the fault information. Among them, the controller can be a processor such as a single-chip microcomputer, and the fault information can include circuit short circuit, open circuit, etc. When the non-addressed node is used to detect fire, the environmental parameters can include temperature, smoke concentration, etc. When the non-addressed node is used to detect floods, the environmental parameters can include pressure, humidity, etc. It should be noted that the non-addressed node can be used to detect different environmental disasters, and different environmental disasters can correspond to different environmental parameters. The present invention does not limit the application scenarios and environmental parameters of the non-addressed nodes.

[0033] In the above embodiment, when the non-addressed node is used to detect a fire, it can be set in an office building, a residential building, a commercial building, etc. The non-addressed node can be partitioned, and the same or different numbers of non-addressed nodes exist in different partitions. The addressable host can be set in a device room, a property center, etc. When the non-addressed node detects a fire, the fault information can be sent to the addressable host through the address-to-non-addressed node, and the addressable host can determine the partition where the fire occurs.

[0034] Through the present invention, the addressing-to-non-addressing device includes a non-addressing node state monitoring module, wherein the non-addressing node state monitoring module is connected to the non-addressing node, and is used to monitor the voltage in the loop where the non-addressing node is located. The non-addressing node is a node that does not support protocol data transmission, and is used to detect the environmental parameters of the target area. When the environmental parameters are abnormal, the non-addressing node is in an alarm state, so that the voltage in the loop where the non-addressing node is located changes; a controller, the controller is connected to the non-addressing node state monitoring module, and the controller is also configured to be connected to the addressing host, and is used to receive the voltage detected by the non-addressing node state monitoring module, and determine fault information based on the voltage, and send the fault information to the addressing host to instruct the addressing host to determine the alarm state based on the fault information. Since the non-addressing node can be in an alarm state when it detects that the environmental parameters of the target area are abnormal, at this time, the voltage in the loop where the non-addressing node is located changes. After the non-addressed node status monitoring module detects the voltage, it sends the voltage to the controller. The controller is configured to connect to the addressed host. After receiving the voltage detected by the non-addressed node status monitoring module, the fault information can be determined according to the voltage and sent to the addressed host, that is, the communication between the non-addressed node and the addressed host is realized. Therefore, the problem that the non-addressed node cannot communicate with the addressed host in the related art can be solved, and the effect of the non-addressed node communicating with the addressed host can be achieved.

[0035] In an exemplary embodiment, the non-addressed node status monitoring module includes: a voltage-dividing resistor, a first voltage detection submodule, a second voltage detection submodule and a current-limiting resistor; the first end of the voltage-dividing resistor is used to receive a power signal, the first voltage detection submodule is used to detect a first voltage at the first end of the voltage-dividing resistor, the second voltage detection submodule is used to detect a second voltage at the second end of the voltage-dividing resistor, the second end of the voltage-dividing resistor is connected to the input end of the non-addressed node, the ground end of the non-addressed node is grounded, and the current-limiting resistor is connected in parallel with the non-addressed node. In this embodiment, the structural diagram of the non-addressed node status monitoring module can be found in the attached Figure 2 ,like Figure 2 As shown, the first voltage detection submodule can detect DC voltage 1, the second voltage detection submodule can detect voltage 2, the power supply information can be a DC signal, and the non-addressed node can include all non-addressed nodes in a certain partition. All non-addressed nodes in a certain partition are connected in parallel, and the current limiting resistor is connected in parallel with the non-addressed node. Such a setting can effectively prevent excessive current from causing damage to the non-addressed node. At the same time, through the cooperation of the voltage dividing resistor and the voltage detection submodule, the voltage change in the loop can be detected more accurately, which is suitable for environments requiring high-precision monitoring.

[0036] In an exemplary embodiment, the controller determines the fault information based on the voltage, including: determining the voltage difference between the first voltage and the second voltage; determining the ratio between the voltage difference and the resistance value of the voltage divider resistor; and determining the fault information based on the relationship between the ratio and a preset current threshold. Figure 2 , the impedance of the non-addressed node itself is relatively large, assuming that the current limiting resistor is R current limiting, and the voltage dividing resistor is R voltage dividing; assuming that the voltage detected by DC voltage 1 is V1 (corresponding to the above-mentioned first voltage), and the voltage detected by voltage 2 is V2 (corresponding to the above-mentioned second voltage), then the current I in the actual line is I= (V1-V2) / R 分压 ;

[0037] (1) When the line is normal, the line current consists of two parts. The first part is the current flowing through the current limiting resistor, I 限流 =V1 / R 限流 The second part of the current is the total current I of all non-addressed nodes connected to the output terminal of the addressing-to-non-addressing device 节点 ; At this time, the output current of the addressing-to-non-addressing device I=I 正常 = I 限流 +I 节点 .

[0038] (2) When the line is broken, the current limiting resistor is disconnected, and the resistance of the output circuit increases greatly. At this time, the output current I 断 ≈I 节点 .

[0039] (3) When the line alarms, the line current consists of three parts. The first part of the current is the current flowing through the current limiting resistor, I 限流 =V 输出 / R 限流 The second part of the current is the total current I of all the non-alarmed non-addressed nodes connected to the output terminal of the addressing-to-non-addressing device 节点 The third part of the current is the alarm current I drawn by the non-addressed node of the alarm 火警 .

[0040] At this time, the output current I 火 = I 限流 +I 节点 +I 火警 .

[0041] (4) When the line is short-circuited, the output line resistance of the address-to-non-address device is almost 0. The current I 短 For I 短 ≈V1 / R 分压 ;I 短It increases dramatically, much larger than the current drawn when the node alarms.

[0042] When the addressable to non-addressable device is in normal state, open circuit state, short circuit state and fire state, the current is clearly distinguished. Therefore, a suitable preset current threshold can be set to distinguish various line states, and the actual current value in the loop can be obtained according to the formula I=(V1-V2) / R voltage division area, and then the line state can be determined by judging which interval it is in. The corresponding event information, that is, the fault information, is reported by the controller to realize the state interaction between the non-addressable node and the addressed host.

[0043] In the above embodiment, by calculating the ratio of the voltage difference to the resistance value, the controller can more accurately determine the alarm status of the non-addressed node, avoiding false alarms and missed alarms, and improving the stability and reliability of the system. This design is particularly important in alarm systems that need to cover a wide area, such as large commercial buildings and residential areas, and can effectively reduce maintenance costs and misoperation.

[0044] In an exemplary embodiment, the non-addressable node status monitoring module further includes: a fuse, and the second end of the voltage-dividing resistor is connected to the input end of the non-addressable node through the fuse. Figure 2 The non-addressed node status monitoring module also includes a fuse. The setting of the fuse can effectively prevent circuit overload and protect the non-addressed nodes from damage. It is suitable for environments with unstable power supply or potential circuit risks, ensuring the safe operation of the system.

[0045] In an exemplary embodiment, the non-addressed node status monitoring module further includes: a reset switch, and the ground terminal of the non-addressed node is grounded through the reset switch. Figure 2 The grounding terminal of the non-addressed node can be grounded through the reset switch. When the non-addressed node at the output end of the address-to-non-addressed device needs to be reset, the microcontroller controls the reset switch to disconnect the connection between the output loop line and the ground, and power off the non-addressed node to achieve the purpose of resetting the non-addressed node. The introduction of the reset switch enables the non-addressed node to be automatically or manually reset after the alarm state is released, which simplifies the system operation process and improves the user experience.

[0046] In an exemplary embodiment, the addressing-to-non-addressing device further includes: a power supply communication module and a power supply switching module; the first power supply interface of the controller communicates with the addressing host through the power supply communication module; the power supply switching module includes: a power supply communication output control switch, the controller is connected to the power supply communication module through the power supply communication output control switch, and the control end of the power supply communication output control switch is connected to the controller; the second power supply interface of the controller is used to connect to the power supply, and the controller is used to control the power supply communication output control switch to switch between power supply communication and power supply. In this embodiment, the structural diagram of the addressing-to-non-addressing device can be found in the attached Figure 3 ,like Figure 3 As shown, the power supply communication module can be a two-bus communication module. The first power interface of the controller can communicate with the addressable host through the two buses. The two buses can both communicate with the device and supply power to the device. The output end of the addressable-to-non-addressable device is mainly connected to all non-addressable nodes in a certain partition. When the output line fails or the non-addressable node detects a fire alarm current, the addressable-to-non-addressable device can monitor the output line current state, determine the line fault or fire alarm information, and report the fault event or fire alarm event to the addressable host through the two buses, thereby realizing the status monitoring of the non-addressable node by the addressable host.

[0047] In the above embodiment, the controller may include one UART (Universal Asynchronous Receiver / Transmitter) for communicating with the second bus of the addressed host; at least three ADCs (Analog-to-Digital Converters), one ADC for detecting whether the DC power supply is connected, and the other two ADCs for detecting the status of the non-addressed node lines; several groups of GPIOs (general purpose input and output ports), mainly used to control the on and off of LED lights, power off of non-addressed node lines, etc. The power supply communication module can connect the first power interface of the addressed host and the controller, such as UART, through the second bus to realize data transmission between the addressed host and the addressed-to-non-addressed device.

[0048] In the above embodiment, the schematic diagram of the power supply switching module can be found in the attached Figure 4 ,like Figure 4As shown, the power supply communication output control switch can be a two-bus output control switch. The two-bus is a signal composed of high and low levels with a data protocol. When it is detected that the external DC power supply is not connected, the two-bus output control switch controls the two-bus output to the rear pole. When it is detected that the external DC power supply is connected, the single-chip microcomputer controls the two-bus output control switch to turn off the two-bus rear pole output, and the external DC power supply supplies power to the non-addressed nodes. At the same time, if the external DC power supply is disconnected, the DC power input detection module will detect that the external DC power supply is disconnected, and the single-chip microcomputer will control the two-bus output control switch to turn on the two-bus rear pole output and continue to supply power to the non-addressed nodes. This design can ensure that the system can still operate normally when the power supply communication module fails or the power supply is unstable. It is suitable for critical facilities that require high reliability and ensures the continuous operation capability of the system.

[0049] In an exemplary embodiment, the power supply switching module further includes a diode, and the power supply communication output control switch is connected to the controller via the diode. Figure 4 The power supply switching module also includes a diode. When it is detected that the external DC power supply is not connected, the two-bus output control switch controls the two-bus output to the rear pole, and after diode rectification, it supplies power to the non-addressed node. The introduction of the diode can prevent the reverse flow of current and protect the controller from damage. It is suitable for environments that require two-way communication or have the risk of reverse current, such as multi-zone alarm systems, remote monitoring systems, etc., and enhances the protection capability of the system.

[0050] In an exemplary embodiment, the power supply switching module further includes an energy storage capacitor, and the energy storage capacitor is connected to the second power supply interface. Figure 4 The power supply switching module also includes an energy storage capacitor. When it is detected that the external DC power supply is not connected, the second bus output control switch controls the second bus to output to the rear pole. After diode rectification and the effect of the energy storage electrolytic capacitor, it becomes several stable DC voltage signals to power the non-addressed nodes. The energy storage electrolytic capacitor can ensure that the non-addressed nodes are not disconnected from the time when the external DC power supply is disconnected to the time when the DC power supply input detection module detects the start of the second bus rear pole output.

[0051] In an exemplary embodiment, the addressing-to-non-addressing device further includes a power supply input detection module, the power supply input detection module is connected to the second power supply interface and the controller, and the power supply input detection module is used to detect the voltage at the second power supply interface; the controller is used to control the power supply communication output control switch to be disconnected when the voltage at the second power supply interface is within a first range, and the controller is also used to control the power supply communication output control switch to be turned on when the voltage at the second power supply interface is outside the first range. In this embodiment, continue to refer to the attached Figure 3The power supply input detection module can be a DC power supply input detection module. The schematic diagram of the power supply input detection module can be found in the attached Figure 5 ,like Figure 5 As shown, the DC power input detection module has been detecting the voltage status of the DC power input interface in real time, and the ADC value of the corresponding sampling port is set to Value ADC When the power is not connected, Value ADC Close to 0, set the ADC judgment threshold when the power is not connected to A, when Value ADC If it is less than A, the power supply is not connected; if the threshold of low voltage connection of the power supply is B, then Value ADC The value should be greater than A and less than or equal to B; if the threshold of high voltage access to the power supply is C, then Value ADC The value should be greater than or equal to C; then when Value ADC When it is greater than B and less than C, the DC power supply is connected normally. When A, B, and C are set within the first range, the device that supplies power to the non-addressed node is determined.

[0052] In the above embodiment, the addressing-to-non-addressing device is applied in an alarm system. The schematic diagram of the alarm system structure can be found in the attached Figure 6 ,like Figure 6 As shown, the addressed-to-non-addressed device can be connected to a DC power supply and an addressed host. The DC power supply can be an optional power supply. When the DC power supply is not connected, the addressed-to-non-addressed device is powered by the addressed host. When the DC power supply is connected, the non-addressed node is powered by the DC power supply; the output end of the addressed-to-non-addressed device can be connected to n non-addressed nodes; the value of n is determined by the static power consumption of the non-addressed nodes; for example, the addressed-to-non-addressed device requires that the total power consumption of all non-addressed nodes at the output end shall not be greater than 1.8mA when static. If the static power consumption of a single non-addressed node is 60uA, the maximum load capacity of the non-addressed node is 1.8mA / 60uA=30. Of course, a certain margin needs to be reserved in the application, and the value of n can be 25. The line detection resistor is mainly used to detect line abnormalities. It is generally connected to the end. When the line is broken at any position, the line detection resistor can be disconnected from the loop.

[0053] According to another embodiment of the present invention, an alarm system is provided, comprising: the addressable-to-non-addressable device described in any one of the above embodiments; an addressed host, the addressable-to-non-addressable device being connected to the addressed host; and a non-addressable node, the non-addressable node being connected to the addressed host via the addressable-to-non-addressable device.

[0054] In this embodiment, the structural diagram of the alarm system can be found in the attached Figure 6, including an addressable-to-non-addressable device, an addressed host, and a non-addressable node. Among them, there can be multiple addressable-to-non-addressable devices, one addressed host, and multiple non-addressable nodes. That is, one addressed host can be connected to multiple addressable-to-non-addressable devices, and one partition can correspond to one addressable-to-non-addressable device. A partition can include multiple non-addressable nodes, that is, one addressable-to-non-addressable device can be connected to multiple non-addressable nodes in a partition. This alarm system can not only effectively monitor and process the alarm information of non-addressable nodes, but also communicate with the addressed host, realizing compatibility between nodes of different technical standards.

[0055] Through the present invention, the addressing-to-non-addressing device includes a non-addressing node state monitoring module, wherein the non-addressing node state monitoring module is connected to the non-addressing node, and is used to monitor the voltage in the loop where the non-addressing node is located. The non-addressing node is a node that does not support protocol data transmission, and is used to detect the environmental parameters of the target area. When the environmental parameters are abnormal, the non-addressing node is in an alarm state, so that the voltage in the loop where the non-addressing node is located changes; a controller, the controller is connected to the non-addressing node state monitoring module, and the controller is also configured to be connected to the addressing host, and is used to receive the voltage detected by the non-addressing node state monitoring module, and determine fault information based on the voltage, and send the fault information to the addressing host to instruct the addressing host to determine the alarm state based on the fault information. Since the non-addressing node can be in an alarm state when it detects that the environmental parameters of the target area are abnormal, at this time, the voltage in the loop where the non-addressing node is located changes. After the non-addressed node status monitoring module detects the voltage, it sends the voltage to the controller. The controller is configured to connect to the addressed host. After receiving the voltage detected by the non-addressed node status monitoring module, the fault information can be determined according to the voltage and sent to the addressed host, that is, the communication between the non-addressed node and the addressed host is realized. Therefore, the problem that the non-addressed node cannot communicate with the addressed host in the related art can be solved, and the effect of the non-addressed node communicating with the addressed host can be achieved.

[0056] In an exemplary embodiment, the alarm system further includes a line detection resistor, which is connected in series with the non-addressed node. In this embodiment, when there are multiple non-addressed nodes, the multiple non-addressed nodes can be connected in parallel, and the line detection resistor can be connected in series with the parallel portion. The line detection resistor is mainly used to detect line abnormalities and is generally connected to the end. When the line at any position is broken, the line detection resistor can be disconnected from the loop.

[0057] In an exemplary embodiment, the alarm system further comprises a power supply, and the power supply is connected to the addressable to non-addressable device.
