Description

Network-based dimming data hot backup method, system, equipment and storage medium

Technical Field

The invention relates to the field of lighting control, in particular to a network-based dimming data hot backup method, system, device and storage medium.

Background

In the field of stage lighting, along with more and more abundant applied scenes, the number of lamps required to be controlled by a control system is more and more, and higher requirements are provided for the real-time computing capability of the control system. And a single host can limit the viewing angle of the observed light effect, and is not convenient for being responsible for the light debugging of the scene. The professional stage dimming console needs a large control loop, and the existing large-loop dimming console (more than 2000 loops) uses a standard PC computer system to process a large amount of control data in order to meet the requirements of large-capacity and high-speed data processing, so that a computer system based on the PC system is used as a main processing unit and needs to be managed by adopting an operating system, such as DOS, Windows and the like, and meanwhile, storage devices such as hard disks and the like are also required to be arranged, the system is too complex and expensive, the risk of virus intrusion into the system and breakdown exist, the field performance is interrupted, and the existing PC system has movable memory banks, CPUs, hard disks, ISAs and PCI slots, and system faults can be caused by transportation, humidity, dust, connector oxidation and the like.

At present, the problem of data synchronization of real-time detection cannot be solved by the existing dimming control console, so that troubles are brought to analysis of lamplight operators; moreover, because the stage lighting control device has a large amount of control units (i.e. data sources) such as the push rod potentiometers and the keys as replay tools (for example, 2048-grid data is recorded in each push rod potentiometer), in the conventional control process, only any tool needs to be operated, and all data in the tool needs to participate in calculation, so that the whole calculation data is large, the calculation is slow, the calculation period is far beyond the specified calculation period, and the requirements of the current development cannot be met.

Although the host based on the PC and the powerful embedded processor is widely used to improve the computing power, sometimes a plurality of hosts are needed to complete the whole computation and output, how to better utilize the computing power of the plurality of hosts to share the whole computing power requirement, how to realize the hot backup to ensure the safety of performance activities, how to improve the data transmission efficiency, and other series of problems need to be solved urgently.

In the system, as long as the data table in the network is received by the master/slave, the receiver can synchronously receive and update the data of the sender, and when the sender fails, the receiver can continue working at a breakpoint. The safety of the system can be ensured. The system is disabled only if all the masters/slaves fail and do not receive the data tables. Namely, in the prior art, data synchronization is mainly performed through cold backup, and the cold backup has the defect that the recovery only can be provided to a certain time point when the cold backup is used alone.

In a lighting system, a control party is responsible for real-time calculation and output of data, and does not simply send out a pre-stored instruction set, so that how to maintain process data is extremely important, and because the data changes continuously, the processes need to be backed up in a hot mode, and the process is guaranteed not to be lost when power is cut off, and not only the instruction set is backed up. That is to say: in the lighting system, only the calculated data is meaningless to back up, and all objects must be backed up, so that once a fault occurs, the backup machine can also complete a large amount of real-time calculation and output instructions and data.

Therefore, the invention provides a network-based dimming data hot backup method, system, device and storage medium.

After the invention is used, the method for synchronizing the states of the sensing encoder/push rod type control devices comprises the following steps: the lamplight engineer operates a data input unit of A, a service logic and calculation unit of A records the state of the device, the input unit is connected with A through an industrial bus, including but not limited to data transmission protocols such as CAN/RS485/RS232, specifically, newly adding/deleting/changing objects and values, performing streaming processing, and throwing the objects and the values into a network, and after the rest B/C/D … are received, performing combination processing, and reversely controlling the state of the device through a working bus of B, such as the position of an electric push rod, the on-off of an indicator light and the like. In fact, what we call as a hot backup is synchronization that must include a control device of an input data unit, for example, a is currently a host, a user is controlling through a, a failure occurs suddenly, B takes over the work to become the host, the user continues to operate through B, the content of the operation is undoubtedly the beginning of "power off" when the failure of a continues to occur, if the control device of B is not synchronized with a in real time, abrupt change of data occurs when the user starts to operate B to control, and an error of a control instruction is caused. Specifically, for example, the electric push rod is used as a potentiometer, one function of the potentiometer is to control the brightness of light, if A is controlled to be 100%, a fault occurs at the moment, B takes over, if the electric push rod of B is above 0%, if the electric push rod of B is not synchronized to be 100%, an error instruction is sent, and therefore the real-time synchronization of the states of the control devices is needed.

A master-slave switching mechanism: the master machine and each slave machine form a management group, the master machine has management authority and can invite a certain slave machine to join in the Session, or force a certain slave machine to leave the Session, the slave machine can only apply for joining in the Session, and whether the slave machine can join is determined by the master machine. All machine local of the management group has a management group device list, which includes basic information of all devices, such as MAC address, IP address, Session ID, name, etc. Each member of the "management group", including the host, sends a "heartbeat packet" to the network, which generally takes a frequency of approximately 20-40HZ and contains the basic information.

When any slave machine is overtime and does not receive the heartbeat packet of the master machine, and simultaneously can receive the heartbeat packets of any other member, the master machine is considered to be lost, the former slave machine is called as a new master machine according to the sequence in the list, in the above situation, when only one slave machine exists, the slave machine is changed into the new master machine, and at this time, the management group is the slave machine. And when the master computer is overtime and cannot receive any slave computer heartbeat packet, forcibly leaving the slave computer from the session, deleting the slave computer from the equipment table, and informing other members of the management group, wherein when only one slave computer exists, the slave computer is the master computer in the management group. When a certain 'host' which is lost is applied for online again, the incumbent host finds that the host is also the Master identity and the session ID is the same, and the incumbent host judges whether to allow the host to join the session and requires to change the identity of the host to be a slave, for example, if the network cable of the host is unplugged and plugged, the above situation occurs.

The hot backup in the invention can be a method for backing up the database by adopting an archivelog mode under the condition that the database is operated. I.e. hot backup, is a backup in which the system is in a normal operating state. Therefore, if you have a cold backup and a hot backup file, more information can be recovered using these data when a problem occurs. Hot backup requires that the database operate in Archivelog () mode and requires a large amount of archive space. Once the database is running in the archivelog state, a backup may be made.

1. The hot backup refers to that under normal conditions, two redundancies work simultaneously, when a certain redundancy fails, the system can cut off the failure redundancy, start a single redundancy mode and degrade work.

2. In the running state, the switch blades are all at the switch-on position, and all relay protection and automatic control devices are put into, control, signal, switch-on and protection power supplies are all sent

3. Other advantages of using hot standby with the switch off and the blade in the on position include:

1. the backup can be carried out in tablespace or at the file level of the database, and the backup time is short.

2. The database is still available at the time of backup.

3. A second level recovery (to some point in time) can be achieved.

4. Recovery can be made to almost all database entities

5. Recovery is fast, in most cases while the database is still working.

The network-based dimming data hot backup method can ensure that both the lamp and the control element can be reliably backed up in real time through the hot backup of the dimming parameter and the state parameter of the control element, so that the slave computer can accurately output instructions and data after completing real-time calculation, and the robustness of the system is enhanced.

The specific embodiment of the invention is as follows:

fig. 2 is a schematic diagram of a system architecture in the network-based dimming data hot backup method according to the present invention. Fig. 3 is a schematic diagram of a tree data table in the network-based dimming data hot backup method of the present invention. As shown in figures 2 and 3 of the drawings,

a control end cluster connected to the same Ethernet switch 2 is arranged, the control end cluster comprises a master 11 and three

slaves

12, 13 and 14, and the Ethernet switch 2 is connected with and controls the working states of lamp sets (31, 32, 33 … … 3N). And establishing a mapping relation table in the Ethernet switch, wherein the mapping relation table comprises the name of the control end of each control end and the corresponding MAC address, IP address and Session ID.

And each control end establishes a tree data table based on the connection relation of lamps in the lamp group, and each node in the tree data table stores the dimming parameter of a lamp node and the state parameter of a control element for controlling the lamp node. And the tree data tables of the slave machines are respectively based on the tree data table of the master machine for data synchronization. The control state parameters configure the state of the corresponding control in real time. Wherein the control member state parameter at least comprises the key state of the control member and/or the current position of the control member in the control stroke. Referring to fig. 3, one or more data tables with tree structures are designed to store data results of the service logic and the computing unit, and all objects and values corresponding to the objects. The data table adopts a C + + object-oriented conceptual design, various types are derived from the basic types step by step, and data are stored in the class member objects. The objects of each class are the "nodes" in the tree data table. And after the programs of the respective service units of the master and the slave are started, establishing the data table in respective memories, and continuously changing the data table according to the change of the services. The changes in the data table are: three types are added/deleted/numerical changed. And adding an object, namely a node, adding the object, deleting the object, namely deleting the object, wherein the value change refers to the change of the value of the member object.

The master 11 and the three

slaves

12, 13 and 14 send heartbeat packets to each other in time. When the slave 14 receives only the heartbeat packets of the

other slaves

12 and 13 and does not receive the heartbeat packet of the master 11 (the master 11 fails suddenly), the slave takes the other slave 12 in the preset ranking sequence (in the embodiment, the preset ranking sequence is the master 11, the slaves 12, the slaves 13 and the slaves 14) which is the most front slave 12 as the master of the slave 14 and performs data synchronization.

Since the slave 12 takes over the work to become the master, the user continues to operate through the slave 12 at this time, the operation content is undoubtedly the 'power-off' start when the fault of the master 11 occurs, the dimming parameters of all the lights and the state parameters of the control elements correspondingly controlling the lights are completely hot-backed up, the control strokes of the control elements corresponding to the state parameters of the control elements are associated with the current dimming parameters, and the real-time synchronization of the states of the control elements ensures that the subsequent control instructions cannot generate errors.

Or, when an offline master 11 re-applies for online, the current master 12 adds the offline master 11 as a slave in the mapping relationship table, and notifies other slaves. The heartbeat packet at least comprises at least one of a control end name, an MAC address, an IP address and a Session ID, and the frequency of the heartbeat packet is 20HZ to 40 HZ.

Or, when the master 11 still does not receive the heartbeat packet of any slave 13 after time out, the slave 13 is deleted from the mapping relation table and notified to

other slaves

12 and 14.
