Description

540203 is often constituted by but with the protection of the line system. It is connected to the device by a router, and it can be used for external applications. Electricity needs pieces. This data router provides a cable system, especially in a local network. 1 < < J. 'U._1_ 5. Description of the invention (1) The present invention relates to a structured electrical sighting system for structural electricity. BACKGROUND OF THE INVENTION A structured cable system is in use. Such systems provide standardized use. Generally, structured cables are twisted copper. Structured electrical thin line signals, and existing infrastructure roads (LAN) and wide area network (WAN) bit rate data communication signals for alarm and security. Network devices, wiring bridges, routers, various devices, data servos, and other network devices. All of them require power. The power consumed by the pieces is powered by internal or provided alternating current (AC) power. Today, all non- Automatically feed internal or external batteries, except to connect a power source. The installation of the network device is complicated and its cost is limited by the power wiring and the need to establish and maintain both power supply and distribution. The other network is used in the infrastructure of public facilities. The conventional system installed in accordance with a predetermined standard is used for telephone, data communication and access control. The Ethernet network transfers and distributes high-level components or components between network devices, which can include a hub, a switch, a desktop personal computer with a network interface card (NIC), and a portable computer. All These devices work in common. In each case, these batteries are supplied by or from the basic components of the electric power network, that is, including one or more network connections, and conditions that need to be connected to the power source, such conditions make The location of the network wiring for network components. Finally, the individual network must be connected. One is for connection to a data communication network.

Description of the invention (2) In addition, in order for the network devices to be operable even when the power supply is partially or completely cut off or powered off, each network device must be added to an internal battery backup system, or it must be connected continuously. Electric power supply (UP S). Depending on the application, the number of network devices that must be operated during a power failure of a building, such as when used with IP or LAN phones, can be very high. Therefore, it is better to make every non-battery-operated network device no longer need to be connected to a public AC power source (that is, a standard AC socket), in addition to being connected to a network. This can significantly reduce the number of cables, AC sockets and related wiring, thus simplifying the installation of network components. In addition, this can also provide a cost-effective way to provide a continuous power supply for multiple network devices. It must be pointed out here that the original data communications network infrastructure was designed to be used most effectively to transmit high-bandwidth, low-power data communications signals rather than power. The IEEE 802.3 standard stipulates that the voltage transmitted by a transmission cable must be insulated and balanced with reference to the ground at both ends. Class 3 to 5 LAN cables, RJ-4 5 connectors, line interfaces of network devices, and all IEEE 8 0 2 3 compatible devices 5 in the network were originally designed with insufficient power transmission capacity. To operate most network devices. Therefore, 'any plan to use LAN basic equipment to simultaneously solve power distribution and provide network data communication should propose the following points: (1) When using LAN basic equipment for power distribution, the network bit error rate (biterr 〇rrate, BER) exceeds the allowable level, and must not interfere with normal data communications in any way, (2) the power on the LAN infrastructure equipment must not cause any harm or danger to users and network maintenance personnel; (3) the LAN infrastructure equipment

V. Description of the invention (3) The power on the other side is not a standard LAN device designed to receive power from the data communication network and must not be harmful or cause damage; and (4) the power on the data communication network & Do not reduce network reliability. There are systems in the technology community that use power networks to transmit data communications signals. Power lines and body systems are well known, and their function is to superimpose relatively high-frequency data signals on low-frequency power cable lines. However, these systems were originally designed to operate on power lines, which are quite different from L A N. The design and structure of the L A N medium is for transmitting data communication signals. Therefore, the design of its windings, connections, circuit interfaces and terminal devices is not designed to handle high power. This is quite different from stacking low-power (10w energy level) data communication signals on a power line network. Fig. 25 is a block diagram showing an example of a prior art data communication network, in which the network components are coupled to a common AC main power source. The network in this example is used to illustrate the various network components commonly found in a LAN environment.

For example, there is only a relatively small part of network components, such as the hub, and other sources, while others, such as routers and routers, need to be connected to a dedicated uninterruptible power supply for power. Important network components receive their operations and components via the LAN infrastructure. One benefit is that it can reduce the security bar feed of network terminal equipment.

Each SPEAR 324 is connected to a power source 132 to receive power from there. I can understand that the position of the power source 32 can be outside the center} 〇 〇 〇. The power source 132 may be provided with a power-off standby device, such as a battery connector. _ Each coupler 320 has two ports, one of which is preferably connected to one port of the LAN switch 134, and the other is preferably connected to a LAN node via a communication cable. The function of the coupler 32 is preferably to couple electric power to the communication cable without substantially interfering with data communication on the communication cable. The role of the wave-flight device 3 2 2 is to avoid unfavorable port-to-port and line-to-line coupling (also commonly referred to as “crosstalk”), and to block the noise generated by the power source 3 2 from entering the communication cable. ^ Take a central management and control subsystem 3 2 6 (usually in the form of a micro-control ^) to control the operation of the power supply 1 32, the coupler 32 0, the filter 322, and the spEAR 3 24.

The power source 182 may be provided with a power failure backup device, such as a battery connector. The filtering effect is best to avoid unfavorable coupling between ports and pairs (also known as "crosstalk"), and block noise generated by the power supply 182 from entering the communication cable. Preferably a central management and control subsystem 3 7 6 (usually in the form of a micro-controller) controls the operation of the power supply 1 82, the filters 3 7 2 and SPEAR 3 74. It can be seen from the embodiment shown in FIG. 4B that a coupler is not provided because the power and data are transmitted on a separate twisted pair. The data transmitted on the conductor via the power interface is largely unaffected by the operation of the power interface. · I can understand that the power supply 3 2 (Figure 3 A), power supply 8 2 (Figure 3 B), power supply 1 2 2 (Figure 4 A), and power supply 1 8 2 (Figure 4 B) are along a pair of conductors (of which One is a positive conductor, indicated by a + sign; the other is a negative conductor, indicated by a _ sign, to provide output power to SPEAR 224 (Figure 3A), SPEAR 274 (Figure 3B), SPEAR 324 (Figure 4A), and SPEAR 374 (Figure 4B).

The voltage input received by 132 (Figure 4A) or 182 (Figure 4B)-Vin provides a voltage output -VQUt, which is usually no different from the voltage input -Vin. The current-sensing output of 4 0 2 is supplied to most of the comparators 4 q 4. Comparator 4 0 4 also receives each reference voltage Vref from each programmable reference voltage source 4 (usually in an A / D converter). Implementation). The programmable reference voltage source 4 0 6 preferably receives from the management and control circuits 2 2 6 (Figure 3A), 276 (Figure 3B), 326 (Figure 4A) and 3 7 6 (Figure 4B) via a bus 4 0 7 ) Control input. Or, the voltage source 406 need not be programmable.

The output of the comparator 404 is sent to a current limiter and a switch 408. This switch receives the input voltage Vln via the current sensor 402 and provides a current-limiting voltage output VQut. The output voltages + vout and -v〇ut are taken as inputs to an analog digital (A / D) and converted to 4 0 9 'The digits of VQut are indicated there, that is, the difference between + and -VQut. It is output to the management and control circuit 226 (FIG. 3A), 276 (FIG. 3B), 326 (FIG. 4A), and 376 (FIG. 4B) via the bus 407. The output of the comparator 4 0 4 is preferably output to the management and control circuit 2 6 (FIG. 3A), 2 7 6 (FIG. 3B), 3 2 6 (FIG. 4A), and 3 7 6 (Figure 4B) " *, as a monitor input, provides information about the DC current flowing through SPEAR.

The output of some comparators 4 0 4 is directly supplied to the current limiter and switch 408, and the output of other comparators 4 0 4 is supplied to the current limit via a timer 4 1 Q and a positive.器 与 开关 4 〇8. The output is directly supplied to the comparator 4 0 4 which is limited to the switch 4 0 8 and provides a very high threshold immediate limit, while the output is supplied to the current limit via a timer 4 1 0 and a flip-flop 4 2 Comparator 4 0 4 with switch 4 8 provides a relatively low threshold delay action interruption.

V. 4 Explanation (59) Positive and negative 4 1 2 responds to external inputs. These external inputs enable management and control circuits 226 (Figure 3A), 276 (Figure 3B), 326 (Figure 4A) and 376 (Figure 4B). The operation of the current limiter and switch 408 can be remotely controlled via the bus bar 407. I can understand that the above SPEAR circuit can also be operated on the negative lead. In this case, a short-circuit wire should be connected to VQut. : One can further understand that the components of § p E A R can also be constructed in another order.

Please refer to Figs. 8A-8E, which show simplified block diagrams of different embodiments of the coupler used in the embodiments of Figs. 3A and 4A. The common purpose of these different embodiments is to couple DC power to the communication cable without affecting the balance along the communication cable, while at the same time producing only minimal changes in its line impedance, and preventing line transformers coupled to the line from occurring. Saturated or burned. Figure 8A illustrates a coupler 6 0, such as coupler 2 2 0 (Figure 3 A) or coupler 3 2 0 (Figure 4 A). Such a coupler is suitable for use in a LAN according to a preferred embodiment of the present invention. Each coupler includes a pair of additional transformers 6 1 0. The transformer 6 1 0 is usually a 1: 1 transformer, which is characterized in that the secondary coil has a central tap, and the DC voltage is fed to the two wires of a twisted pair via this tap. This structure can maintain the balance of the line and prevent the core from being saturated. This structure has another advantage, that is, because two wires of a double twisted pair are transmitted simultaneously

5. Description of the invention (62) An additional transformer is required. This structure has another advantage, that is, because two wires of a twisted pair line transmit the same voltage at the same time, a short circuit occurring along the line will not cause power overload. Another advantage of this structure is that if a LAN node is not specifically used to receive power on a double twisted line, it will not cause the LAN node to be burned. Fig. 8E illustrates a coupler 700, such as a coupler 220 (Fig. 3A) or a coupler 320 (Fig. 4A) suitable for use in a LAN according to a preferred embodiment of the present invention. This type of coupling is an automatic balanced common mode coupling circuit. The coupler 7 0 0 includes two pairs of adjustable active balancing circuits 7 0 2 and 7 0 4. These two pairs of circuits cooperate with the induction and control circuits 7 0 6 and 7 0 8 respectively. A special feature of the embodiment shown in FIG. 8E is that two pairs of adjustable active balancing circuits 7 0 2 and 7 0 4 operating in cooperation with the induction and control circuits 7 0 6 and 7 0 8 can be coupled to them. Maintain the exact same voltage on each wire connected to the twisted pair. Generally, the output end of a L A N switch is coupled to the communication cable via an isolation transformer 7 1 0. The isolation transformer 7 1 0 is not part of the coupler 7 0 0. When exactly the same voltage is applied to each of the wires constituting the twisted pair as described above, the DC voltage of the secondary winding of the isolation transformer 7 10 does not pass, so no DC current flows there. This eliminates DC isolation capacitors, thus improving the balance and impedance matching of the coupler. I can understand that in a theoretically ideal system, any active balancing provided by the embodiment shown in Fig. 8E may not be needed. However, in reality, the DC resistance along the entire communication cable system varies, so

Page 66 540203 V. Description of the invention (63) The DC voltage on each wire of the double twisted pair will not be exactly the same if there is no active balance, so a DC voltage drop will be generated across the transformer 7 10 secondary winding This will cause the transformer 7 1 0 to saturate or burn out. Please refer to FIG. 8F ', which shows a simplified schematic diagram of a preferred embodiment of the embodiment in FIG. 8E. Since the same reference numerals are used in FIG. 8E and FIG. 8F, the schematic diagram of FIG. 8F should be self-explanatory. Therefore, for the sake of brevity, no other text description is provided here. Referring now to FIG. 8G, a simplified schematic diagram of a preferred embodiment of the embodiment of FIG. 8E is shown. Since the same reference numerals are used in Fig. 8E and Fig. 8G, the outline drawing of Fig. 8G should be self-explanatory. Therefore, for the sake of brevity, no other text description is provided here. # Please refer to Figs. 9A-9G, which shows simplified block diagrams and outlines of various embodiments of the separators that are preferably used with the couplers of Figs. 8A-8G in the embodiment of Figs. 1A, 2A and 7A. Illustration. In addition to the components included in Figures 9 A-9 G, these dividers can include appropriate filters to avoid cross-pair and port-to-port crosstalk. The common purpose of these different embodiments is to decouple the DC power from the communication cable without affecting the balance along the communication cable, while at the same time producing only minimal changes in its line impedance and preventing coupling to the line The line transformer is saturated or burned. Fig. 9A illustrates a divider 1660, such as divider 14 2 (Fig. 2A), suitable for use in L A N according to a preferred embodiment of the present invention. This divider includes an additional pair of transformers 1610 per channel. Transformer 1610. Usually a 1: 1 transformer, which is characterized in that the primary coil has a central tap, and the DC voltage is

Page 67, 5x03, 5. Description of the invention (64) This tap has another advantage from the structure of a double twisted wire, and it has the same voltage. When the same voltage is received, another advantage of this knot is when receiving power. FIG. 9B illustrates a split and a pair used for a pair of additional voltage regulators according to the present invention, which are characterized by individual windings 1 6 3 4 containers 16 4 0. This capacitor is used for high frequency signals to isolate the two winding resistance . This structure causes a negative voltage. This structure has a net zero DC current, so two wires are drawn out when DC current is transmitted in the direction. Keep the line balanced and prevent the core from being saturated. This kind of junction means that the two wires of the double twisted pair wire will not cause power overload due to the short circuit occurring along the wire at the same time. Yes, if a LAN node is not specially used in a twisted pair cable, it will not cause burn-out of this LAN node. The spacer 16 2 0, such as the spacer 1 4 2 (Fig. 2A), is suitable for L A N of the preferred embodiment. This divider includes 1630 per transformer. Transformer 1630 is usually 1: 1 and includes a primary coil 1 6 3 2, which is divided into two and 1 6 3 6. One electrical device can be connected between windings 1 6 3 4 and 1 6 3 6 in series to effectively connect the two windings for data signals, but it is effective when used for DC. The two windings can be transmitted through the same twisted pair respectively. One of the positive advantages is that it applies No. 1J through the double twisted wires. If the double twisted wires are the same, there is a magnetic field in addition to the magnetic field. Fig. 9C illustrates a divider 1650, such as divider 14.2 (Fig. 2A), suitable for use with a capacitor 1660 according to the present invention, which is quite simple and does not require a preferred embodiment of the LAN . This divider includes a circuit that effectively blocks DC from entering the node. This junction requires an additional transformer. Fig. 9D illustrates a divider 1670, such as divider 1 42 (Fig. 2A), suitable for use in a L A N according to a preferred embodiment of the present invention. This divider includes two

Page 68 "oa. V. Description of the invention (65) For capacitors 680, 169, they can effectively block DC from entering the node circuit. This structure is also quite simple and does not require additional transformers. This structure has another advantage, that is, because the two wires of the twisted pair wire transmit the same voltage at the same time, a short circuit occurring along the wire will not cause a force overload. Another advantage of this structure is that if a LAN node is not specifically used to receive power on a twisted pair line, it will not cause the LAN node to be burned. Figure 9E illustrates a divider 1700, such as a divider. 1 4 2 (FIG. 2A) is suitable for a LAN according to a preferred embodiment of the present invention. This divider is a self-balancing common-mode coupling circuit. The divider 17 0 0 includes two pairs of adjustable active balancing circuits 1 70 2 and 1 7 0 4. These two pairs of circuits cooperate with the induction and control circuits 1 7 06 and 17 0 8 respectively. A special feature of the embodiment shown in FIG. 9E is that two pairs of adjustable active balancing circuits j 0 2 1 7 〇4 operating in cooperation with the induction and control circuits 17 0 6 and 1 7 0 8 can be used at It is necessary to maintain exactly the same voltage on each wire of the coupled twisted pair. And a /, the output terminal of a LAN node is connected through an isolation transformer 17 1 0 —ί t i ϊ ΐ. Isolation transformer 1710 is not the phase of the separator 1700; each wire of the f twisted wire is completely applied as described before, because :: Electricity = Transformer Transformer Γ710 The secondary winding has no DC voltage, so the separation is improved器 二 ί S = f 二 In this way, dc isolation capacitors can be eliminated, and we can understand the role of impedance matching. In any ideal system, as shown in Fig. 9E, the active balance can be eliminated without the need for the active balance provided by the steam engine. However, in practice

At 540203 on page 69 "...: V. In the description of the invention (66), because the DC resistance along the entire communication cable system changes, if the DC voltage on each wire of the double twisted pair is not actively balanced, it will It will not be exactly the same, so a DC voltage drop is generated across the primary winding of the transformer 1710, which will cause the transformer 1710 to saturate or burn out. Please refer to FIG. 9F, which shows a simplified schematic diagram of a part of the preferred embodiment of the embodiment of FIG. 9E, including components 1 70 2 and 1 7 0 therein. Since the same reference numerals are used in FIG. 9E and FIG. 9F, the schematic diagram of FIG. 9F should be self-explanatory. Therefore, for the sake of brevity, no other text description is provided here. Please refer to FIG. 9G, which shows a simplified schematic diagram of a part of the preferred embodiment of the embodiment of FIG. 9E, including the components 1704 and 1708. Since the same reference numerals are used in Fig. 9E and Fig. 9G, the outline of Fig. 9G should be self-explanatory. Therefore, for the sake of brevity, no other text description is provided here. The purpose of providing the circuits not shown in Figs. 9F and 9G is to ensure that the voltages on the two wires of the double twisted wires connected to them are the same to prevent the current from flowing through the transformer 1710 (Fig. 9E). Utilizing the control of the components 17 0 6 and 17 0 8 to change the current flowing through the active filter 17 0 2 and 17 0 4 respectively, the circuit of Figs. 9 F and 9 G can achieve this purpose.

Please refer to FIG. 16, which shows a schematic flowchart of the power management of the network of FIGS. 10 A, 10 B, 1 1 A, and 1 1 B during normal operation and reduced power mode. As shown in Figure 16, the power management and control unit 2038 (Figure 10A), 2088 (Figure 10B), 2 1 3 3 (Figure 1A), or 2 1 3 8 ( FIG. 11B) is a management power supply to at least a part of the LAN nodes through a communication cable, preferably based on a predetermined function management, which will be described below with reference to FIG. 17. Power management and control unit 2038 (Figure 10A), 2088 (Figure 10B),

2 1 33 (Figure 1 A) or 21 38 (Figure 1 1 B) monitors and manages the power consumption of these LAN nodes. It senses overcurrent conditions and performs power cuts as appropriate. Power management and control unit 2038 (Figure 10A), 2088 (Figure 10B), 2 1 3 3 (Figure 1 A) or 2 1 3 8 (Figure 1 B) can use non-spontaneous power management mode or spontaneous power management Mode to operate. The operating mode is usually selected when the architecture is RAN, however, the operating mode can also be selected after the architecture.

In the non-spontaneous power management mode operation, if the power management and control unit perceives that there is insufficient power on the communication cable to be transmitted to each LAN node, it will supply a reduced amount of power to at least some LAN nodes and provide control information. Or other control inputs to the LAN nodes to make them operate in reduced power mode. In the spontaneous power management mode operation, when certain activities are reduced, such as at night and on weekends, management control reduces the available power in order to save energy costs. In one embodiment of the autonomous power management mode operation, management determines which nodes receive which power at which moments. This is an example of a non-dynamic, non-conditional reaction, which will not be discussed in detail in the following description.

Page 540 203 Description of the invention (86) In another embodiment of the spontaneous power management mode operation, the available power at a known time is determined by management, and the function of the present invention regards the power controlled by such management as available electric power. The operation of the present invention may be similar to that of non-spontaneous power management, but its thresholds and responses may be different. Referring now to FIG. 17, there is shown a preferred method of supplying power to at least a portion of the LAN nodes according to the present invention. After the center 2 0 1 0 (Fig. 10A), 2060 (Fig. 10B) or the power and management subsystem, Tong 2130 (Fig. 11A), 2180 (Fig. 11B) are initially set, the communication power is queried. The connection between the line and the nodes that want to transmit power via the communication cable. Initial setting of central 2 0 1 0 (Fig. 1 A), 2 0 6 0 (Fig. 10 B) or subsystem 2 1 3 0 (Fig. 1 A), 2 1 8 0 (Fig. 1 1 B) It is preferable to include an automatic start-up test procedure to ensure the correct operation of each component of the center 2 1 0 (Figure 10 A), 2 0 6 0 (Figure 10 B) or the subsystem 2 1 3 0 (Figure 1 1 A), 2 1 8 0 (Figure 1 1 B) (if present) and management station 2040 (Figure 10A), 2090 (Figure 10B), 2140 (Figure 1 1 A) or 2 1 9 0 (Figure 11 B) Communication, for each node to determine the ideal operating parameters of the hub or subsystem, and set up an internal database, which includes the ideal operating parameters of each node. During normal system operation, operators using the management workstations 2040 (Figure 10A), 2090 (Figure 10B), 2140 (Figure 11A) or 2 1 0 (Figure 1 1 B) can modify different operating parameters of each node. The query is described in more detail below with reference to FIGS. 18A and 18B. If the inquired node is considered to have the characteristic of π power supply on the LAN and is classified as a node that wants to obtain transmission power via a communication cable in the internal database, set the SPEAR based on the content of the internal database Parameters and transmit power to the node via a communication cable. when necessary,

If the absolute value of the voltage is higher than a predetermined programmable threshold V 1, the line is classified as a voltage with an external source on the line. In this case, power is not supplied to the line via a communication cable. If the absolute value of the voltage is not higher than the predetermined programmable threshold V 1, the 5 P E A R current limit I 0 is set to a predetermined programmable value I L 1, and the SP E A R switch 4 0 8 is turned on (FIG. 5). The voltage and current at the SPEAR output are then measured, usually at three predetermined programmable times T 1, T 2 and T 3. The times T 1, T 2 and T 3 are usually determined by the time constant determined by the inductance of a typical N I C transformer, and the maximum bad line DC resistance between the maximum allowable communication line length between the hub or subsystem and a node. In general, T1, T2, and T3 are equal to 1, 2, 10 times the above-mentioned time constant. Typical values of T 1, T 2 and T 3 are 4 seconds, 8 seconds, and 40 seconds, respectively. Based on these measurements, the status of the nodes and the lines connected to them can be determined. The following is a typical set of determinations:

Most or all of the functions described below use a basic monitoring and management technology, which is now explained as follows: According to a preferred embodiment of the present invention, the power consumption monitoring and management functions during normal operation include sensing all Current on the line. This perception is preferably performed in a usual cyclic manner. Then compare the perceived current with a programmable reference value for each line. Additionally or alternatively, voltage can be sensed and used for this purpose. Based on this comparison result, each node can be classified as over-current, 彳 current, or normal. The overcurrent category includes programmable thresholds such as high overcurrent and normal overcurrent. The normal category may have sub-categories such as active mode, sleep mode, and low power mode. The function of this system can control the operation of a node classified as overcurrent in the following ways: If the current at a node exceeds the general overcurrent threshold for at least a predetermined time, the supply to the node is cut off after the predetermined time. electric power. The current supplied to a node must not exceed the high overcurrent threshold under any circumstances. According to a preferred embodiment of the present invention, different intermediate thresholds may be defined between the general over-current threshold and the high over-current threshold, and the aforementioned determination of the power cut-off time is a function of which intermediate threshold is exceeded.

If T P C / TP A is usually less than 0.8, all power will be supplied to other nodes one by one based on the priority order. If TPC / TPA is usually greater than 0.95, the power supply to individual nodes will be cut off one by one on the basis of priority. If TPC / TPA is usually equal to or greater than 0.8, but usually less than or equal to 0.95, then query whether there is a new node that needs power. If so, and a node with a lower priority is currently receiving power, cut off the power supply to the node with a lower priority and turn on the power to the node with a higher priority.

Fig. 20A shows a basic technique for all functional operations or reduced functional operations in non-spontaneous power management according to a preferred embodiment of the present invention. As shown in Figure 20A, the system first determines the total power available to it and the total power currently supplied to all nodes.

As shown in Figure 20C, the system first determines the total power available to it and the total power currently supplied to all nodes. Then determine the relationship between the current total power consumption (T P C) and the current total available power (T P A). If T P C / TP A is usually less than 0.8, power will be supplied to other nodes one by one based on the priority order controlled by the waiting sequence, or additional power will be supplied to each node, usually on the basis of advanced (waiting sequence) first supply. If TPC / m T P A is usually greater than 0.95, the power supply to individual nodes will be reduced one by one on the basis of priority. If the TPC / TPA is usually equal to or greater than 0.8, but is usually lower than or equal to 0.95, then query whether there is any node requiring additional power or whether there are new nodes requiring power. If so, the node is added to the end of the waiting sequence. Fig. 20D shows all functional operation or reduction functional operation techniques based on time-sharing priority order for non-spontaneous power management according to a preferred embodiment of the present invention. As shown in Figure 20D, the system first determines the total power available to it and the total power currently supplied to all nodes. Then determine the relationship between the current total power consumption (T PC) and the current total available power (TP A). If the TPC / TPA is usually less than 0.8, the power is supplied to other nodes one by one on a time-shared priority basis, or additional power is supplied to each node. Usually, the node with the longest usage period is cut off first. If TPC / TPA is usually greater than 0.95, the power supply to individual nodes will be reduced one by one based on the priority order.

Page 99 540203 Description of the invention (96) If TPC / TP Α is usually equal to or greater than 0.8, but usually less than or equal to 0.95, then query whether there is a new node that requires power or whether there is a node that requires additional power. If there is, and a lower priority node is perceived to have received power for a long time and exceeds a predetermined minimum time, and it is currently receiving power, reduce the power supply of the lower priority node and provide power Give higher priority nodes. Now refer to the schematic flowcharts of Figures 2 A, 2 1 B, 2 1 C, and 2 1 D, each of which shows a possible mechanism for performing the node startup in the spontaneous power management steps in the flowchart of Figure 16 Sleep mode operation. m Figure 2 A shows a node operating in sleep mode due to lack of activity for at least a predetermined time. As shown in Figure 2A, first measure the time period T D 1 of the node since the previous activity. If T D 1 usually exceeds a few seconds or minutes, and there is no input from the user or the system to prohibit sleep mode operation, the node operates in sleep mode. This mode of operation usually can substantially reduce power requirements. Fig. 2B shows a node operating in a sleep mode due to lack of communication for at least a predetermined time. As shown in FIG. 2B, the time period T D 2 of the node since the previous communication is first measured. If T D 2 usually exceeds a few seconds or minutes and there is no input from the user or the system to prohibit sleep mode operation, the node operates in sleep mode. This mode of operation usually can substantially reduce power requirements. Figure 2C shows a node's activity in a time slot that occurs periodically in response to timing control. If there is no system or user input, it will operate in sleep mode. As shown in Figure 2C, the day-to-day gap is defined as time T D 3 and the rest of the day is determined

The node can determine whether it is currently in the time slot T D 3, and if not, that is, in the remaining time TD4, it operates in the sleep mode. Figure 2D shows a node operating in sleep mode due to perceived fault conditions. As shown in Figure 2 1 D, the nodes regularly perform self-tests. The purpose of the self-test may be to communicate with the hub or power and management subsystem. If the node passes the test, it operates in the normal way. If the node fails the test, it operates in sleep mode. Please refer to the schematic flowcharts of Figures 2 A, 2 2 B, 2 2 C, and 2 2 D, each of which shows a possible mechanism for performing the autonomous power management steps in the flowchart of Figure 16 by the central or Sleep mode operation initiated by the power and management subsystem. • Figure 2 A shows a node operating in sleep mode due to lack of activity for at least a predetermined time. As shown in Fig. 2A, first measure the time period T D 1 of the node as perceived by the hub or the power and management subsystem since the previous activity. If T D 1 usually exceeds a few seconds or minutes, and there is no input from the user or the system that prohibits the sleep mode operation, the node operates in the sleep mode. This operation mode can generally reduce the power demand substantially. Figure 2 2B shows a node operating in sleep mode due to lack of communication for at least a predetermined time. As shown in Figure 2 2B, the time period T D 2 since the previous communication between the nodes perceived by the hub or the power supply and the management subsystem is measured. If T D 2 usually exceeds a few seconds or minutes, and there is no input from the user or the system that prohibits the sleep mode operation, the node operates in the sleep mode. This operation mode can generally reduce the power demand substantially. Figure 2C shows a node response from the hub or power and management subsystem

P.101 5 «29 The timing control of the main and invention description (98) is active in the time slot that occurs periodically. If there is no system or user input, it will operate in sleep mode. As shown in Figure 2 2C, the time slot is defined as time T D 3 and the remaining time is defined as T D 4. The node can judge whether it is currently in the time slot T D 3, and if not, that is, in the remaining time T D 4, then it operates in the sleep mode. Alternatively, the hub or the power supply and management subsystem can manage the power supply to the nodes according to the aforementioned timing control, thereby controlling the operation of the nodes. Figure 2 D shows a node operating in sleep mode because the hub or power and management subsystem senses a fault. As shown in Figure 2 2D, the hub or power and management subsystem regularly performs node tests. The purpose of the self-test may be to communicate with the hub or power and management subsystem. If the node passes the test, it will operate normally. If the node fails the test, it operates in sleep mode.

Then, the relationship between the current total power consumption (TP C) and the current total configured power (T P L) is determined. If T P C / TP L is usually less than 0.8, all power will be supplied to other nodes one by one based on the priority order. If TPC / TPL is usually greater than 0.95, then _

If the TPC / TPL is usually equal to or greater than 0.8, but is usually lower than or equal to 0.95, then query whether there is a new node that needs power. If so, and a node with a lower priority is currently receiving power, cut off the power supply to the node with a lower priority and turn on the power to the node with a higher priority.

In this case, the known node can be given the highest priority and the function of Figure 2 3 A can be applied. Once the emergency situation no longer exists, the priority of the known node is returned to its general priority, and the machine of Figure 2 3 A is operated.

If so, and a node with a lower priority is perceived to have received power for a longer period of time And exceeds a predetermined minimum time, and it is currently receiving power, it will cut off the power of the lower priority node and turn on the power of the higher priority node. I can understand that it is usually best to notify the node about its power in advance Changes in supply. This can be achieved by transmitting signals along the communication cable in a general data transmission mode or any other suitable mode. _ Now refer to Figure 2 4 A, 2 4 B, 2 4 C and 2 4 D are schematic flowcharts, each of which shows a possible mechanism for executing the spontaneous power in the flowchart of FIG. 16

Fig. 2A shows a basic technique for all functional operations or reduced functional operations in spontaneous power management according to a preferred embodiment of the present invention. As shown in Figure 2A, the system first determines the total power allocated to the system and the total power currently supplied to all nodes. Then determine the relationship between the current total power consumption (TPPC) and the current total configured power (TPL). The technique of Figure 2 4 A can be used in the environment of Figure 2 A. If T P C / TP L is usually less than 0.8, all power will be supplied to other nodes one by one on the basis of priority. If TPC / TPL is usually greater than 0.95, the power supply to individual nodes will be reduced one by one on the basis of priority. If the TPC / TPL is usually equal to or greater than 0.8, but usually less than or equal to 0.95, then query whether there is a new node that needs power. If there is, and a node with a lower priority is currently receiving power, the power supply to the node with a lower priority is reduced, and additional power is provided to the node with a higher priority. Fig. 2B shows a full-function operation or a reduced-function operation technology with an emergency override principle for spontaneous power management according to a preferred embodiment of the present invention. The technique of Figure 24 B can be used in the functional environment of Figure 24 A. As shown in Figure 2 4B, the system can sense the urgent need for additional power at a known node. In this case, the known node can be given the highest priority and the function of Figure 2 4 A can be applied. Once the emergency situation no longer exists, the priority of the known node will return to its general priority and operate the function of Figure 24A. According to another alternative embodiment of the present invention, the emergency mode function may be super

The performance of the tube-over-flow machine is to be prioritized. 0 / r / r is the tube power supply, and the general supply point is to cut any spontaneous power management restrictions. Fig. 2C shows all the functional operation or decrement operation techniques used in spontaneous power management according to a preferred embodiment of the present invention to wait for sequence control priority. As shown in Figure 2C, the system first determines the total power allocated to the system and the total power currently supplied to all nodes. Then determine the relationship between TPC and TPL. The technique of Fig. 24C can be used in the environment of Fig. 23A. m If T P C / TP L is usually less than 0.8, power is supplied to other nodes one by one according to the priority basis controlled by the waiting sequence, usually on the basis of advanced (equal sequence) first supply. If the TPC / TPL is usually greater than 0.95, the power supply to individual nodes will be reduced one by one based on the priority. If the TPC / TPL is usually equal to or greater than 0 · 8, but usually less than or equal to 9 5, then query whether there is a new node that requires additional power. If so, add that point to the bottom of the wait sequence. Fig. 2D shows all functional operation or reduction machine operation techniques based on a time-sharing priority order used in spontaneous power management according to a preferred embodiment of the present invention. As shown in Figure 2 D, the system first determines the power allocated to the system and the total power it currently supplies to all nodes. Then determine the relationship between the current power consumption (TPC) and the current configured total power (TPL). The technique of Fig. 24D can be used in the environment of Fig. 23A. If T P C / T P L is usually less than 0.8, power should be supplied to other nodes one by one based on the time-sharing priority order, and usually the longest period of use is cut off first. If TPC / TPL is usually greater than 0.95, the power supply to individual nodes will be cut off one by one on the basis of priority.

5402 ^ 9 Description (ill) Power supply 3 1 8 4 Connect an AC power source via a connector or cable 3 1 9 2. Alternatively, power can be received from another power / data combiner unit. The function of the power supply 3 1 8 4 can provide the power required for the operation of the power / data combiner unit 3 1 800 itself, and the total energy required for the network devices connected downstream of the unit 3 180 and powered by a remote source. The structure of the power supply 3 1 8 4 is best to support the worst case energy, that is, the energy required for one channel multiplied by the maximum energy of the number of channels. Or, assuming that the power consumption of all channels was previously predicted, the structure of the power supply 3 1 8 4 can only support a small amount of power. The function of the filtering and protection circuit 3 1 8 2 allows high-frequency data communication signals to pass through from the input to the output without interference. Circuit 3 1 8 2 prevents the low-impedance output of the power supply from causing attenuation of data communication signals, and prevents the communication signals on one channel from leaking to the other channel through the shared power supply unit 3 1 8 4, which also prevents crosstalk. The function of this circuit can also filter out the high frequency pulsations and noise caused by switching the power supply, and provide high output impedance from the power supply for high frequency use. Other functions of the filtering and protection circuit 3 1 8 2 include: limiting the available power of each channel according to a predetermined level, sensing the current of each pair, minimum and maximum current threshold reference levels, imbalance or current leakage detection, And the ability to connect and disconnect power from each channel. The minimum and maximum current threshold reference levels can be fixed or controlled by a management unit, depending on the implementation and architecture of the system. An important function of circuit 3182 is that it will cut off a shorted or faulty port, leaving the channels in other operations unaffected. The controller 3 1 8 6 is properly programmed, and its functions can manage and control the operation of various components in the power / data combiner 3 1 80, and can manage an external management

The function of this controller is to communicate with a management unit connected locally or remotely via a network. This controller allows online modification of the power currently distributed to each channel. Other functions include: status reports, such as reporting the power consumption of each channel, any channel failures, and any failures within the power / data combiner unit itself. In a monolithic embodiment, the function of the power / data combiner unit is incorporated into a conventional LAN connection hub or switch, such as 10, 100, or 100 0 B a s e T. The hub's internal power supply has been modified to support higher loads and remote feed functions for normal hub operation. A line interface circuit is inserted between the output end and the internal network circuit of the hub. In addition, filtering and protection circuits are added to couple the line interface circuit and the power supply. Each standard LAN port is replaced with a data plus power port. Such a monolithic embodiment can reduce the overall system cost, reduce the required space, and reduce the complexity of the network. However, such embodiments do require modifications to the hub or switch of the practice. Regardless of the external or monolithic embodiment, the data received by the power / data combiner is bidirectionally transmitted between the input of each channel and its corresponding channel output. The amount of output power allocated to each output channel can be set independently. In addition, each output channel is self-protected against short circuits and overloads. In addition, regarding the external power / data combiner embodiment, two additional LAN ports can be selectively provided. It can be set as an input LAN port and an output LAN port, whereby the two ports can be bridged to each other during normal operation. The hub or switch of the model is fed through the output port L A N. The input L A N ports are connected to upstream network devices, such as hubs or

However, this embodiment requires modification of the custom network device. Assuming that each network bee consumes the maximum configured output power at the same time, it is not efficient to construct a power transmission and distribution network in terms of complexity and cost. In addition, such a power network may create a power bottleneck π on the data network, and will force the use of special cables that do not conform to the general L A N equipment standards. In addition, the equipment used to implement such a power network is likely to exceed the thermal and power specifications of a standard network architecture equipment box, making it impossible to accommodate such equipment. (The standard network architecture equipment box is specially designed to accommodate stackable hubs, switches, routers, and various network management units.) Therefore, the power supply system on the LAN of the present invention can be used when constructing a power network. Indicate (1) statistics of expected power consumption during normal network operation, and (2) expected power consumption during emergency operation when the building is powered off. The management unit 3 1 6 4 (Figure 2 6 A) includes software that can be run on any personal computer or server connected to the network. The function of this management unit can transmit telemetry and control information to various LAN power supply components, such as power / data combiners and splitters distributed throughout the network. The data communication network itself can transmit data information between the devices and management units with power supply functions on the LAN. The management unit provides monitoring and power supply functions. The power supply function allocates the available power resources to the managed network data services in an analogous manner and can be used to structure the power path across the network from source to network. The network administrator can decide which system method to use for each network port that appears to be unloaded, overloaded, or leaks to the surface. The power to the failed port can be temporarily cut off or limited to an acceptable value. Power suspension status can be followed.

29 Repair the iF port automatically or manually. Each can be individually structured according to the system's setup architecture. Please note that each power / data combiner can be constructed to be managed independently or through external control. Each power / data combiner may include a dedicated LAN data connection or may include serial / parallel communication with a network host computer system, and the network host computer system transmits telemetry and control data to the network LAN. When the building is powered off, some network devices and nodes, such as hubs, routers, bridges, switches, etc., may need to be bypassed to maintain data and power continuity between important network nodes, terminals and devices. The power supplied by a single large L A N channel should, in most cases, be sufficient to operate most network devices. However, such a LAN channel may not be sufficient to operate a normal network hub / switch and all network devices connected to it at the same time. In addition, LAN devices are usually useless unless they receive both power and data communications. The function of the power supply system on the LAN of the present invention can maintain the power and data communication flow in the event of a power failure. In the event of a building power failure, its L A N node units, that is, hubs, switches, etc., and its network components will switch to reduced power operation mode. When a device is in a reduced-power operation mode, it will reduce its data processing bandwidth and / or processing activity, keep only a few ports active, and temporarily close the remaining ports to reduce its total power consumption. Therefore, a battery-based UPS can be used to support most important network components for a long time. Those skilled in the art can understand that the present invention is not limited by the contents shown and described above.
