Fig. 2 is a first structural diagram of a device detection system according to an embodiment of the present application. As shown in fig. 2, the present system includes: the detection device 210, the communication bus 107, and the plurality of serial servers include serial server a221, serial server B222, and serial server C223, wherein,

serial server a221, serial server B222, and serial server C223 correspond to detected device a301, detected device B302, and detected device C303, respectively, serial server a221, serial server B222, and serial server C223 are connected to communication bus 107, serial server a221, serial server B222, and serial server C223 are also connected to corresponding detected device a301, detected device B302, and detected device C303, respectively, serial server a221, serial server B222, and serial server C223 are configured to acquire device information of corresponding detected devices, and transmit the device information to detected device 210 through communication bus 107;

the detection device 210 is provided with a plurality of communication ports including a communication port a211, a communication port B212, and a communication port C213, where the communication port a211, the communication port B212, and the communication port C213 are respectively connected to the communication bus 107, and the detection device 210 is configured to obtain device information through the communication bus 107 and the corresponding communication ports, and determine a device detection result according to the device information.

In the present embodiment, the detection device 210 and the serial server a221, the serial server B222, and the serial server C223 in the device detection system are connected through the communication bus 107. The equipment detection system is mainly applied to power environment detection of a communication office, and is generally provided with a detection center, a region detection center, a detection unit and a detection module. The detection center and the region detection center are arranged for adapting to the requirements of centralized detection, centralized maintenance and centralized management, and the difference is that the corresponding regions are different in size. The detection unit conveys and processes the data acquired by the detection module. When the power environment is detected, the types of the equipment to be accessed are large, and the quantity of the equipment is large. In order to reduce the cost of the device detection system while simplifying the constitution of the system, the detection device 210 is used as a detection unit of the device detection system.

In this embodiment, the detection device 210 may be a computer. By adopting the detection device 210, the system cost is reduced, and under the condition that the device detection system needs to detect new devices, the hardware upgrading and reconstruction can be omitted, so that the maintenance workload is reduced.

When using a computer as a detection unit, the device detection system needs to take into account that the computer typically does not have an interface that satisfies the number of devices to be detected in the system. A virtual serial port mode can be adopted, and a certain number of serial ports, such as a communication port A211, a communication port B212 and a communication port C213, are virtualized on a computer according to different IP addresses so as to meet the number requirements of devices detected by the system. Because the number of the serial ports of the detection devices 210 is greatly increased by adopting the virtual serial ports, 256 virtual serial ports of one detection device 210 can be achieved, and therefore, in one machine room, one or two detection devices 210 can be used for meeting the detection requirement.

Meanwhile, the interface protocol of the computer is generally different from that of the detected devices, so that the serial server is used to connect the detecting device 210 and each detected device. The serial port server provides serial port to network function, can convert the RS-232/485/422 serial port into a transmission control protocol TCP/Internet protocol IP network interface, realize the data bidirectional transparent transmission of the RS-232/485/422 serial port and the transmission control protocol TCP/Internet protocol IP, or support MODBUS protocol bidirectional transmission. The serial port equipment can immediately have a network interface function, is connected with a network for data communication, and expands the communication distance of the serial port equipment. The serial server plays a role of converting the collected data by the interface protocol of the detected device according to the interface protocol of the detection unit and uploading the data to the detection unit.

In this embodiment, the communication bus 107 may be an ethernet. Ethernet is a computer local area network technology that specifies the content of the link, electronic signal and media access layer protocols including the physical layer.

In this embodiment, the detection device 210 and the plurality of serial servers are connected through the communication bus 107 to form a Modbus network. The ModBus network is an industrial communication system, which is formed by connecting a programmable controller with an intelligent terminal and a computer through a public line or a local private line. The system structure comprises hardware and software. It can be used for various data acquisition and process monitoring. The detection device 210 sets the device that is to collect the detection data to a different hardware address, and uses MPLS-VPN technology to communicate the devices of the different rooms with the central room. The MPLS-VPN is to construct an enterprise IP private network on a broadband IP network by adopting an MPLS technology, realize multi-service communication such as cross-regional safe high-speed data and the like, and combine the reliable performance, good expansibility and rich functions of a public network with the safety, flexibility and high efficiency of a private network by combining related technologies such as differential service, traffic engineering and the like.

Optionally, the serial server is specifically configured to:

receiving a command message sent by the detection device 210;

acquiring first equipment information of corresponding detected equipment according to the command message;

performing protocol conversion processing on the first equipment information to obtain second equipment information;

the second device information is sent to the detection device 210 via the communication bus 107.

In this embodiment, the serial server, as a component that enables the detected device to have networking capability in the power environment, converts the device information of the detected device into a protocol based on the requirements of the detection device 210. The first device information is thus detection information based on the interface protocols of the detected device a301, the detected device B302, and the detected device C303, and the second device information is based on the protocols required by the detection device 210. The content of the command message is to inform the serial server to obtain the information of the detected device a301, the detected device B302 and the detected device C303 connected to the serial server, and the command message also includes the format of the protocol to be converted by the serial server required by the detecting device 210. After receiving the command message sent by the detecting device 210, the serial server obtains the first device information of the detected device a301, the detected device B302 and the detected device C303, and then converts the first device information into the second device information according to the format of the protocol in the command message. Subsequently, the first device information is transmitted to the detection device 210 through the communication bus 107.

Optionally, the detection device 210 is specifically configured to:

through the communication port C213, the communication port a211, the communication port B212, and the communication bus 107 send command messages to the serial server a221, the serial server B222, and the serial server C223;

the communication port a211, the communication port B212, and the communication bus 107 receive the second device information through the communication port C213, and determine a device detection result from the second device information.

In this embodiment, in order to improve the detection efficiency, the detection device 210 uses a multi-threading technology to collect the second device information sent by the serial server a221, the serial server B222, and the serial server C223. Specifically, the detection device 210 first declares a list, storing the command message character string and the number of bytes of the second device information that it desires to return. Subsequently, the detection device 210 initializes the serial port: communication port C213, communication port a211, communication port B212, parameters including serial port name, baud rate, data bits, stop bits, check bits, timeout time, etc. The detection device 210 sends command messages through multiple virtual serial ports at the same time, listens to the multiple virtual serial ports to receive the return values, and jumps out when the number of the return bytes is equal to the number of the expected bytes (the data is received). After that, the detection device 210 analyzes the return value according to the protocol provided by each manufacturer, obtains the device information to be extracted, analyzes and processes it, and determines the detection result of the device. The obtained detection results include normal equipment, equipment failure, equipment abnormality, etc., and according to the detection results, the detection equipment 210 may perform further processing including alarming, or store the detection results in a database, etc.

Optionally, the first device information is RS485 interface based information, and the second device information is transmission control protocol TCP/internet protocol IP based information.

In the embodiment, the detected equipment adopts an RS485 interface, and the RS485 bus is widely applied in industrial control occasions due to the characteristics of simple interface, convenient networking, long transmission distance and the like. The first device information is thus information based on the RS485 interface. Whereas the detection device 210 typically employs a transmission control protocol TCP/internet protocol IP, i.e. a transmission protocol, also referred to as network communication protocol. It is the most basic communication protocol in use of the network. The transmission control protocol TCP/internet protocol IP specifies the standards and methods for communicating portions of the internet. The second device information is thus information based on the transmission control protocol TCP/internet protocol IP.
