With the rapid development of modern network construction, data transmission among all machine rooms is smooth, so that transmission of a large amount of data becomes possible, but the new problem is that hidden dangers occur in the stability and data security of a large amount of small and medium machine rooms dispersed in various places. Therefore, large-scale data rooms are built in various industries and departments, and the data processing and storage are centralized, so that the room maintenance efficiency is improved and the maintenance cost is reduced. At present, after all data machine rooms are communicated based on a high-speed network, a powerful machine room group is formed, and data interaction of machine room pieces can be achieved through interactive transmission of the currently communicated high-speed network, so that the effect of centralizing data processing and storage is achieved.

Moreover, in a data computer room, there are usually thousands of PDUs and dozens of bus duct sensors, and if an abnormal condition occurs in one of the modules, manual troubleshooting will severely restrict the speed of positioning an emergency problem. Overall, the main technical disadvantages are as follows:

Detailed Description

For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

Example 1:

please refer to fig. 1, which is a structural diagram of a data room power distribution equipment management and control system, the system adopts a B/S three-layer architecture, and includes a data processing module and a data acquisition module, and the communication connection mode between the modules is as follows:

the data processing module and the data acquisition module realize bidirectional transparent transmission of working state data of power supply and distribution equipment of a machine room through a serial server;

the data processing module and the data acquisition module have the functions of:

a1) the data acquisition module: the device comprises a data processing module, a register data processing module, a data processing module and a data processing module, wherein the data processing module is used for communicating with machine room power supply and distribution equipment by adopting a Modbus communication protocol, in the communication process, point location information of the register (the point location information of the register is a register value packaged in a response code data part, and the register value is a specific numerical value of an electrical parameter such as voltage, current and active power and the like measured by a sensor in hardware equipment) is extracted from an interactive information frame and processed, and the obtained electrical parameter data reflecting the working state information of the machine room power supply and distribution equipment is sent to the data;

a2) the data processing module: the data acquisition module is used for receiving the electric parameter data acquired by the data acquisition module, storing the received electric parameter data in a database storage mode, and giving an alarm, early warning and/or displaying according to the received electric parameter data, so that remote monitoring of the power distribution equipment of the data machine room is realized.

In this example 1:

the machine room power supply and distribution equipment comprises a port box used for feeding power to a cabinet bus inside a data machine room, a plug box used for power distribution plug-in connection and a power distribution unit-PDU (Power distribution Unit) used for providing power distribution for the machine room power distribution equipment.

Now, taking how to measure physical quantities such as voltage, current, active power, reactive power, apparent power, power factor, temperature, humidity, and the like of a power distribution unit-PDU, and flow direction of measurement data as an example, information interaction between a data acquisition module and a data processing module is described in detail:

first, the PDU is a product that provides power to the cabinet, and has different functions, installation methods, and insertion combinations. The circuit board in one PDU can be divided into two modules with mutually independent functions, wherein the main functional chips of the metering modules are RN8209C and RN8211B which are used for metering physical quantity information such as current, voltage, active power, reactive power and the like in the PDU single-phase circuit, and the RN8209C and the RN8211B carry out data interaction in an SPI serial communication mode;

after the RN8209C and RN8211B chips are used for measuring the electrical parameter information related to the PDU, a UART serial communication mode is adopted based on a serial server to complete data interaction with a data processing module;

secondly, in the data processing module, a mode of integrating a single chip microcomputer RN8213 and an RS-485 transceiver can be considered to complete data interaction between the data processing module and the data acquisition module and data interaction between the data processing module and a main control machine under the data display module; the processing mode for finishing data interaction based on the single chip microcomputer RN8213 and RS-485 transceivers is as follows:

in the aspect of electrical parameter data processing: the received and processed electrical parameter data is packaged into a Modbus-rtu protocol by a singlechip RN 8213;

in terms of interacting with the master machine: and transmitting the encapsulated Modbus-rtu protocol to a master control machine through an RS-485 transceiver based on an RS-485 communication mode, wherein the data flow of the PDU can refer to FIG. 2.

The system adopts a daisy chain bus topological structure based on an RS-485 communication mode, wherein the bus topological structure is a special tree topological structure, and the branch line distance of the bus topological structure is very short without leaving branches. For example, the data processing module is provided with a plurality of RS-485 transceiver devices, and the connection mode between each transceiver device is as follows: 485+ of the A device is connected with 485+ of the B device, 485+ of the B device is connected with 485+ of the C device, and the like. The distance between each device node is generally not more than 0.5 m. Please refer to fig. 3 for a specific RS-485 topology.

The above is based on a1) -a2) to explain the hardware structure of the system bottom layer in practical application.

Referring to fig. 4, it is a flow chart of the execution of the sending thread program and the receiving thread program when executed, in terms of hardware design of the system, the data acquisition module specifically includes a memory and a processor, the memory stores the sending thread program and the receiving thread program, and the two threads work simultaneously but have some relation between timing and flag bits; the sending thread program can realize the following steps (refer to part (a) of fig. 4) when being executed by a processor:

step 1: firstly, initializing a serial port and starting a sending thread;

step 2: reading the slave address and issuing a query code;

and step 3: then, detecting a response code receiving zone bit, judging whether the response code is received or not according to a detected result, if so, returning to the step 2, and entering the next round of inquiry; if not, after the time delay processing, judging whether to quit the current thread, and if not, executing the step again until the thread is finished.

In general, when a sending thread sends a query code to perform polling query on power supply and distribution equipment of a machine room, firstly, a receiving completion flag bit of a response code is queried, and the next polling query is determined to be performed when the response code is received; when the response code is not received, whether the current program is continuously executed or not needs to be judged, if yes, next polling inquiry is carried out, and if not, the sending thread program is quitted; under the current program, in order to ensure the real-time performance of the query of the control instruction and the query code, the method also comprises the steps of checking whether the query instruction and the control instruction (such as the opening and closing of an equipment coil) of a specific register exist or not after the query code is sent, if so, terminating the current polling query, and issuing the specific control instruction and the query code; meanwhile, in order to realize the import of the communication protocol template and ensure that the program obtains the maximum universality, the sending thread also provides the array length of the response code and the number of the query codes required by traversing all registers of the equipment for the receiving thread.

Taking the PDU needing to query the current phase voltage as an example, assume that the slave address of the PDU is 64, the function code is 04, the initial address of the phase voltage register in the device is 00, and the data of the phase voltage occupies one register and is two bytes. The design of the inquiry code and the response code is shown in fig. 5. Since, one information frame contains the content and format: the device address + function code + data + check bit, the device address (slave address) and the function code of the inquiry code and the response code should be kept the same, and the difference between the two is: checking the bits and data portion, wherein:

since the check bits are calculated from all data before the check bits, the data portion of the query code is: the address of a first register and the number of continuous registers, and the data part of the response code is as follows: the total number of bytes and the register value, and the check bit is different when the data content included in the query code and the response code are partially different. For example, the data portion of the check code is: 00000001, slave address 64, function code 04, the corresponding parity bit is 383F. The function of the inquiry code is as follows: the equipment to be inquired, the type of the inquired register and the address and the number of the inquired register are specified, after the system sends the inquiry code, the inquiry code can be transmitted through the bus, and the hardware equipment connected with the inquiry code through the bus can also respond in time when receiving the inquiry code, information required to be fed back to the data acquisition module forms a response code in a form of a second line shown in figure 5 and returns to the bottom layer of the system in time through the bus, and therefore, the acquisition of data of the specified equipment is completed.

The form of the database table for obtaining the slave machine address is shown in table 1, and if data needs to be issued to a certain COM port, the serial port can be inquired from the database and all serial port addresses can be obtained.

TABLE 1 Slave Address field Specification

The receiving thread program can realize the following steps (refer to part (b) of fig. 4) when being executed by a processor:

step 1: initializing a serial port, and starting a receiving thread;

step 2: detecting serial port data, judging whether a response code is received or not, if so, executing the step 3, otherwise, retransmitting the query code, and judging whether the transmission program is successfully executed or not by detecting the serial port data;

and step 3: judging whether the response code data is correct or not through data verification according to the received response code data, and if so, executing a step 4; if not, discarding the error data, and returning to the step 2;

and 4, step 4: storing the correct response code into an array, acquiring the address of the required register data in the array from a database and extracting the address;

and 5: extracting and processing the data part of the response code, processing the data according to a mode of converting a 16-system code into a 10-system code and performing decimal processing, and storing the processed data into a corresponding position of a database; and after the delay setting is carried out, ending the current thread.

In general, a receiving thread receives a response code adapted to the query code, generates a data reception completion flag bit, stores the correct response code into an array if data verification is correct, extracts and processes a data portion of the response code according to an address of register data acquired from a database in the array, and stores the processed data into a corresponding database table in a data processing module.

The response code receiving thread is also responsible for comparing whether the acquired electrical parameters exceed a set threshold value, when the acquired electrical parameters exceed the threshold value, the alarm data are stored in the real-time data table, the information is also required to be stored in the alarm information table, an alarm zone bit is generated to prompt a front end page to generate an alarm prompt window, a buzzer of corresponding alarm equipment is opened, and an alarm short message and a mail are sent. And after the alarm processing is finished, comparing the alarm occurrence time to calculate to obtain the recovery time length.

The above is a detailed description of the execution flow of the sending thread program and the receiving thread program stored in the memory when the sending thread program and the receiving thread program are executed by the processor.
