Description

Electric lighting partition control system addressable picture repeater

Technical field

The invention relates to a partition control function unit of an electric lighting control system, in particular to an addressable picture boundary repeater of an electric lighting partition control system having a drawing boundary function and an addressing function. Applicable to electric lighting control systems with multiple rooms or areas, allowing special rooms or areas to be individually controlled when needed. The so-called room refers to any space for people to move. The so-called area refers to the space in a room or the periphery of the room. Background technique

With the advancement of electronic components and electronic control technology, the electric lighting process has developed into a digital control system, in which the Digital Addressable Lighting Interface (DALI in Europe and America) is specified in Annex E of IEC60929. Most representative. This was originally a specification for fluorescent dimming control, but it was gradually developed into a control system specification covering all electric lighting systems due to its reliability, simplicity, and reasonable price. Especially in the face of worldwide energy and environmental issues, energy-saving technologies are becoming more and more important, and lighting systems that can be automatically controlled are gradually becoming necessary.

The digital electric lighting control system was originally an extension of the calculator technology. The lighting control system that uses the serial bus to transmit control information such as the network is very powerful, but the price is too high and unreasonable. Restrictions, only for some special purposes, are not universal.

The digital addressable lighting interface system was developed successfully in Europe and gradually accepted by the world. The architecture consists essentially of a bus power supply, at least one controller, and a luminaire with a digitally addressable light interface receiver. Each digital addressable light loop can control up to 64 individual luminaires, each of which is assigned an address code during initial setup. According to this address, the system can issue instructions for each luminaire separately. However, in practical applications, the luminaires should be grouped first. After storing the data in the memory of each luminaire, as shown in European Patent EP90100465.6 (USPAT5352957), the instructions can be directly issued for the group. A loop can set up to 16 groups (0~15). Each fixture can belong to several groups at the same time. However, depending on the actual system, some products only allow one group to be set.

The use of the group is very convenient and important. For example, each room is at least one group, so that the controller can control the whole room as a whole, and the controller in the room must also set its control group in advance, so that the instructions can be correctly issued without cluttering. Another example is an office, assuming it includes several rooms and a conference room. For In order to meet the requirements of energy saving, each room must be individually controllable to automatically turn off the illumination or reduce the brightness when no one is present. If the lighting of each room is to be controlled separately, a group code must be assigned separately. The controller and sensor associated with this room must also be set with the same group code. The lights in the conference room may need to be divided into at least three groups, such as the top of the podium, the conference table, and the two sidelights, to accommodate different needs such as speeches, deliberations, multimedia presentations, and briefings. In order to facilitate the direct command of each group of lights, each room can be equipped with a dedicated group controller. As long as the group button of the group controller is pressed, the group of lamps will accept the command. Of course, these connections must be pre-set. OK, otherwise the controller and the controlled luminaire will not be able to connect. For the grouping method of the controller, reference can be made to the German patent DE4327809.4, (USPAT.5544037). The common group controller has four group selection keys.

After the grouping is completed, each group of lights can be separately adjusted to an appropriate brightness to form an overall lighting scene. Some locations, such as multi-purpose conference rooms, may require several different lighting scenarios to suit different needs. In order to avoid the trouble of frequent adjustment, the lighting scene controller can be used to pre-store the data of each group, brightness and other data related to each lighting scene, and only need to press the scene selection button to retrieve the original design. Fixed, common lighting scene controllers generally have 4 to 8 scene keys to choose from.

The addressability of digital addressable lighting interface systems is characterized by the grouping, scene setting, and dimming of the entire system. However, the initial grouping, setting the scene, and setting the brightness can be very complicated and require professional and specialized tools.

A digitally addressable light interface system loop that can have 64 controllers, each with its own address (the sensor is also a controller). Each controller must be pre-set. It has been shown through practical application experience that a digitally addressable lighting interface loop, whose luminaires can only be divided into up to 16 groups, is often insufficiently used, thus creating a limitation. For example, when the number of rooms is a little more or the lighting scene is more complicated, it cannot be handled, and another loop must be added.

In order to relieve the inconvenience caused by the limited grouping and to exempt the complicated setting procedure, Chinese Patent Application No. 200610076528.2, the electric lighting control system and the control method, which are separated by the picture boundary repeater, are proposed by the same applicant of the present invention. The patent application proposes an electrical lighting control technology solution. The technical solution does not take the individual addressing of each luminaire as the control basis, but uses a picture boundary repeater to separate the serial bus drawing boundaries for transmitting control information, naturally forming an independent interval. The communication protocol divides the instructions into system instruction group and interval instruction group. The system instruction can pass through the picture boundary repeater. The interval instruction is valid only in the interval, and cannot cross the picture boundary repeater, so that the system instruction and the interval instruction are respectively It is the responsibility of the division to eliminate the complicated setting work, and each interval controller naturally performs its work within the interval defined by the boundary repeater. Whether it is in the construction, maintenance, expansion and control of lighting systems, it is clear and clear at a glance. In order to meet the needs and practicability of the actual operation of the lighting control, the technical solution is directly controlled by the room or the area. The digital information transmission bus is divided into separate partitions by a picture boundary repeater device. System commands can be forwarded across the repeater; regional commands cannot be truncated across the repeater and can only be valid within the interval defined by the arterial repeater. Various inter-area controllers and sensing controllers, such as personnel detectors, are designed to transmit only interval commands. Since interval instructions cannot cross the picture boundary repeater, they naturally do not interfere with facilities outside their range. For example, in a room detector, when no lights are detected and the lights are turned off, the next room is not affected.

The technical solution, when applied to a remote control device, can further highlight its convenience. In German patent

The remote control described in DE4327809.4 (USPAT5544037) and European Patent EP91201071 (USPAT5565855) requires the remote control to be set. Therefore, if there is a remote control for different rooms, the remote control for each room is required. Special settings are not universal. According to the technical solution provided by the Chinese Patent Application No. 200610076528.2, the remote controller does not need to be set without regional restrictions and can work in any interval. The communication protocol of the electric lighting control system divides the instructions into two groups, one of which is a system instruction group and the other is an interval instruction group.

For system commands, the picture repeater will perform the relay function. The relay function of the picture repeater can be one-way or two-way. For the lighting control in the general living space, the one-way relay can be used. Reverse transmission can be used to report fault information. However, for small-scale applications, it is clear that the lights are working properly. Auto-detection is not necessary, so one-way (forward) relaying is sufficient to reduce costs.

For the interval command, the relay function of the picture repeater will be aborted and essentially form a block, so the interval command will only be valid in the local area bounded by the picture repeater.

The communication protocol may use byte length or byte content, or both. For convenience of comparison, an instruction compatible with Digital Addressable Light Interface (DALI) will be described as an embodiment, for example, the entire disclosure of the present invention. The system broadcast command can be set to two bytes, and the first byte is FF.

The commonly used broadcast system instructions are shown in Table 1.

Table 1 The interval instruction can be set to a single byte, as shown in Table 2:

Table 2

The controlled luminaire has a trusted, decoded, and driven device to accept and execute the command. The interval controller and the sensor controller are mainly based on the transmission interval command, so the control function is limited to the range in which they are located, and the setting procedure is not required for different rooms.

All devices that can send commands have collision detection capability. When a collision occurs, the low potential takes precedence and the high potential retreats.

The picture boundary repeater has a relay and buffer registration function. When a collision occurs, if the relay transmission of the picture boundary repeater needs to be retired, the system command information in the relay will be interrupted, only the input end thereof. It is not affected, and its instruction code continues to be decoded and stored in the memory, waiting for an appropriate time before continuing to resend.

The electric lighting zone control system can isolate the sections so that the whole system, such as a company office, can accept system commands, and in each section, for example, departmental divisions, supervisory rooms, conference rooms, etc. can receive interval instructions in the interval. Internal control of the lighting of various departments, this range of lighting control system, the digital addressable lighting interface lighting control system, grouping restrictions (up to 16 groups), so that multi-room multi-light scene lighting control, is also very easy to achieve.

However, the above system also has its shortcomings. In actual life, when starting the lighting control system, especially the lighting control system that can control multiple rooms, it is often unnecessary to start the whole system at the same time, and only need to start a specific room. For example, the personnel of a certain department should work overtime. When entering the office, they only need to start the department's lights; or when they return home, they just want to light up the living room, and the other rooms remain off. This feature requires the ability to issue instructions for each specific interval, that is, each specific interval or room, requiring a specific address. The present invention proposes an addressable picture boundary repeater device that can be separated and addressable for the above requirements, so that independent control of a specific interval can be realized. Summary of the invention

In order to make the objects, the technical solutions and the advantages of the present invention more comprehensible, the present invention will be further described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, FIG. 1 is a schematic diagram of an electric illumination partition control system of an application boundary repeater/addressable picture boundary repeater provided by the present invention.

The electric lighting zone control system is composed of a bus power supply 5, a system controller 7, a zone controller 8, a human activity sensor 4, and a picture boundary repeater 6 or an addressable picture repeater 600. After the addressable picture repeater 600 is set, it can receive control instructions related to the interval address. In Figure 1, 1 is AC mains, and 2 is a two-phase digital information transmission bus.

The system communication protocol of the present invention divides the instructions into a system instruction group and an interval instruction group, as shown in Fig. 2 and Fig. 3, Fig. 2 is a schematic diagram of system instructions, and Fig. 3 is a schematic diagram of interval instructions.

In Figure 1, 37 is the system instruction, consisting of two bytes of length, 38 is the interval instruction, only one word Section. The highest bit of the system instruction is "1", that is, 2 bytes of 16-bit 0x8000 or more can be classified into system instructions; the highest bit of the interval instruction is "0" for resolution. The instruction sent by the system controller 7 is a 2-byte length system command, and the command transmission is recognized by a start bit, and its termination is recognized by 2 stop bits. The transmission path of the system command is as shown at 9 in Fig. 1, which can be entered into zone b by zone a through picture boundary repeater 6 or addressable picture boundary repeater 600.

As shown in luminaires 3, 37 and 38, the luminaire can accept a 2-byte system command 37 and can also accept a 1-byte interval command 38. The interval controller 8 and the sensor 4 can only transmit the interval command, so the command cannot pass through the picture boundary repeater 6 or the addressable picture boundary repeater 600, and cannot enter the b area, and thus only in the zone a region to which it belongs. Valid, 10 is the interval instruction transmission path and cannot traverse the picture boundary repeater 6 or the addressable picture boundary repeater 600.

As shown in FIG. 4, FIG. 4 is a schematic diagram of an arterial repeater addressing instruction architecture adopted by the communication protocol. In the first byte of the BH architecture, GGGG is the addressing bit, and the second byte BL can be composed of any of the interval instructions. The addressing instruction architecture of the picture boundary repeater is similar to the grouping instruction in the DALI communication protocol, and it is easy to integrate with the DALI system through the bridge technology. A bridge is a conversion device that combines two different systems. It is a common technique in the field of network communication technology and will not be described in detail here. As shown in FIG. 5, FIG. 5 is a structural block diagram of the picture boundary repeater 6 in the electric lighting zone control system, and the picture boundary repeater 6 includes at least a power supply unit 60 and a digital information processing unit 61. The power supply unit 60 is configured to supply power to the digital information processing unit 61 and the downlink bus 2''. The digital information processing unit 61 is generally a digital information processor for relaying and buffering digital information received from the uplink bus 2', and controlling the lamps in the interval in response to the received system command and the interval command for the interval. .

The power supply unit 60 includes a bus power supply 68 and a regulated power supply 69. The bus power supply 68 is used to supply power to the downlink bus 2"; the regulated power supply 69 is used to supply power to the digital information processing unit 61. The bus power supply can be, for example, 5 VDC, and the specifications of the bus power supply can be compared, that is, the accessory E according to EEC60929 is met. The power specification for the digital addressable lighting interface, with a voltage of 11.5 to 22.5V and a current of less than or equal to 250 mA.

The digital information processing unit 61 includes at least an optical isolator 62, a relay controller 63, a shift register 64, a control gate 65, a collision recognition detector 66, and a retransmission controller 67.

The optical isolation device 62 is configured to output the digital information received from the uplink bus 2' to the relay controller, and the digital information of the uplink bus 2' passes through the optical isolation device 62 and enters the relay controller 63.

The relay controller 63 is configured to perform edge detection, waveform reforming, and start bit detection on the digital information received from the optical isolator 62, and identify the system command by comparing the last digits after the start bit. The interval instruction temporarily stores the recognized system command into the shift register 64, and outputs the system command to the control gate 65 or when controlling When the alarm 65 is in the off state, the system command is temporarily stored in the shift register 64, and the identified section instruction is truncated.

The shift register 64 is used to store digital information input by the relay controller. The control gate 65 is configured to drive the switching device of the downlink bus 2" power supply according to the received system command, and transmit the system command to the next section. The collision recognition detector 66 is used for monitoring the collision state, and the control gate is monitored when the collision state is detected. 65. The collision recognition detector 66 can further register and retransmit in a one-way or two-way relay mode when the collision state is detected.

The retransmission controller 67 is configured to send an instruction to the relay controller 63 after a predetermined time interval after the collision occurs or the address comparison coincides, instructing the relay controller 63 to perform the system instruction temporarily stored in the shift register 64. Retransmit all, or only resend its interval control instructions.

The two-phase digital information entering the relay controller 63 is also driven by a control gate 65 to drive the switching device of the downstream bus 2" power supply 68, not shown, to transmit information into the b zone, before being decoded. When the collision recognition detector 66 detects the collision state, the control gate 65 is cut off and stops entering the zone b. Only the storage operation of the shift register 64 does not stop until the relay controller 63 detects that the two stop bits are completed. The storage action of the shift register 64 is stopped after being trusted.

After the retransmission controller 67 waits for an appropriate time delay, the relay controller 63 is instructed to perform retransmission. When retransmitting, the digital data stored in the shift register 64 is first subjected to two-phase modulation coding, and then enters the control gate 65 to drive down. The power supply 68 of the bus transmits information to the downstream bus 2".

The digital information processing unit 61 can be composed of logic circuits, can be made into a single-core integrated circuit, or can be partially or wholly composed of a single-chip microcomputer, which is easily understood by an electronic engineering technician. As shown in FIG. 6, FIG. 6 is a structural block diagram of an addressable picture boundary repeater 600 in the electric lighting partition control system provided by the present invention. The addressable picture boundary repeater 600 is further provided with an addressable unit 640 based on the picture boundary repeater 6 of FIG. 5, and the addressable unit 640 is used for controlling the overall electric lighting control system.

The input terminal of the AND gate A5 is connected to the output terminal of the digital information processing unit instruction high byte register LBH, and the output terminal is connected to the input terminal of the AND gate A6; the input of the digital comparator 647 The terminal is connected to the digital information processing unit to command the output of the high byte register LBH, and the output terminal is connected to the input terminal of the AND gate A6.

The comparison circuit command high byte RXBH is compared with the address set by the dial switch. When the comparison is completely the same, the AND gate A6 outputs a logic information and is locked into the latch 648 for relay control. The device 63 is used. The 648 outputs to the AND gates A7 and A8 at the same time, controls the digital channel during retransmission, A8 controls the channel of the 2-byte system command, and A7 controls the channel of the single-byte interval command. A7 and A8 are simultaneously controlled by the retransmission clock controller 636. When A7 or A8 is turned on, the input terminal AND9 is cut off to avoid interference from the signal transmitted by the upstream terminal 2' during retransmission.

The AND gate A6 is for generating a logic information based on the result of the matching received from the comparison circuit, and storing the logic information in the latch for use by the digital information processing unit.

The latch is used to store the logic information input by the AND gate A6, and output the logic information to the digital information processing unit to control the digital channel of the digital information processing unit at the time of retransmission. Referring again to FIG. 7, in the digital information processing unit 61, the relay controller 63 includes at least a start bit and stop bit detector 631, a decoding recovery device 632, a byte counter 633, a communication arbiter 634, and a system. Instruction checker 635 and retransmission clock controller 636.

The start bit and stop bit detector 63 is configured to receive the digital information input by the optical isolator 62, and output the received digital information to the decoding and restoration device 632.

The byte counter 633 is for generating a first byte and a second byte of digital information, and stores the first byte and the second byte of the digital information into the shift register 64 in accordance with the generated pulse.

The communication arbiter 634 is configured to intercept the interval instructions based on instructions received from the system instruction checker 635, allowing system instructions to pass.

The system command checker 635 is configured to detect the start bit of the digital information, and after determining that the digital information is a system command, instruct the communication arbiter 634 to allow the system command to pass.

The retransmission clock controller 636 is used to provide the clock pulses required for the shift, to determine the retransmitted bytes, and to control the switching of the retransmission process.

In FIG. 7, the decoding recovery means 632 decodes the restored data D and the clock signal CK into the AND gates A1, A3 and the AND gates A2, A4, respectively, and the first byte clock BHT generated by the byte counter 633, The AND gates A1 and A2 are started, and the first byte RXBH of the data D is stored in the shift register 641, and the second byte clock BLT starts the AND gates A3 and A4, and the second byte RXBL of the data D is stored. In shift register 642. After the stop bit is confirmed in time, the representative information is successfully received. The receive success information generator L generates a latch pulse, locks RXBH and RXBL into the 643 (LBH) and 644 (LBL) registers, respectively, and feeds them into the transmit shift register ( In TXBH) 645 and (TXBL) 646, the high-displacement output of shift register 645 is connected to A8, which outputs 2-byte system command data.
