Description
Technical Field
The invention relates to the field of office equipment control, in particular to a data reading method, a data reading device, a data reading system and data reading equipment of printing equipment.
Background
The printing apparatus is a common office apparatus, and its application range is very wide. Whether the ink jet printing equipment or the laser printing equipment needs to use printing equipment consumables, for example, the consumables of the ink jet printing equipment are ink, and the consumables of the laser printing equipment are carbon powder. Further, the printing apparatus is inevitably out of order during use of the printing apparatus. Consumable replacements and failures of printing equipment are often inspected and maintained by professional service personnel. When the number of the printing devices is large and the printing devices are distributed and dispersed, if the printing devices are not patrolled in time, consumables are used up or faults of the printing devices bring inconvenience to users of the printing devices. In addition, with the development of the printing equipment rental industry, in order to realize refined printing equipment management, the renter of the printing equipment needs to acquire information of consumables, faults, maintenance conditions, the number of printing paper sheets, the working time of the printing equipment and the like of the rented printing equipment.
The problem of data acquisition of printing equipment is solved by adopting a data acquisition device in the related art.
In the prior art, a Simple Network Management Protocol (SNMP) is generally used for communication with a printing device. In the SNMP protocol architecture, the printing device runs an SNMP agent in the form of a daemon process that can respond to various request information from the network. The SNMP agent provides a number of Object Identifiers (OIDs for short). An OID is a unique key-value pair, which includes a unique identification of the OID and a corresponding key value. Although each OID has a unique identifier, it is not uniform what data is stored in the key of the OID. That is, after the requester reads data in the key of an OID, what parameters this data represents may be unknown. In order to enable the OID to establish a mapping relationship with the data stored in the key value thereof and enable the requesting party to know what kind of parameter the read data is, the requesting party needs to configure a Management Information Base (MIB) library, which is used to establish a mapping relationship between the OID key value and the data, so that the requesting party can query the corresponding OID from the MIB library according to the data to be read and then read the data to be read from the corresponding OID of the requested party. Various data of the printing apparatus, for example: the basic information of the system, the name of the printing device, the position of the printing device, the network interface information of the printing device, the CPU and load information of the printing device, the fault information of the printing device, the consumable information of the printing device, and the like are all obtained as key values of the OID through commands provided by the SNMP protocol.
However, only the parameters stored in the key values of the common OIDs are fixed, for example, the printing apparatus model information is fixedly stored in the key values of the OIDs named. 1.3.6.1.2.1.1.1.0. However, more OIDs are not fixed, and different MIB libraries (i.e., data reading protocols) are used by respective printing device vendors for different models of printing devices, so that data stored in key values of OIDs of the same name may represent different parameters.
In the related art, the problem of data acquisition difficulty caused by different printing devices using different data reading protocols is solved by a mode of pre-configuring corresponding data reading protocols in firmware of a data acquisition device according to the types of the printing devices.
However, it has been found that the above-mentioned solution has the following disadvantages:
1. different data acquisition devices need to be compatible with different printing equipment models, so that different data reading protocols need to be configured for the data acquisition devices according to the printing equipment models, and the installation cost of the data acquisition devices is increased;
2. the data reading protocol is fixedly configured in the firmware of the data acquisition device, the firmware version of the data acquisition device needs to be remotely upgraded when the data acquisition device is required to be added and the type of the printing equipment is compatible, version management is disordered due to frequent firmware version upgrading, and poor expansibility of the data acquisition device is caused.

Detailed Description
In the present embodiment, a data reading method of a printing apparatus is provided according to an embodiment of the present invention.
Fig. 1 is a flowchart of a data reading method of a printing apparatus according to an embodiment of the present invention. As shown in fig. 1, the process includes the following steps:
step S101, a data acquisition device acquires model information of printing equipment;
step S102, the data acquisition device acquires a data reading protocol of the printing equipment from the server according to the model information;
and step S103, the data acquisition device reads the data of the printing equipment according to the data reading protocol.
Through the steps, the data acquisition device acquires the data reading protocol of the printing equipment from the server side according to the acquired model information of the printing equipment, and then reads the data of the printing equipment according to the data reading protocol, so that the problem that the expansibility and the compatibility of the data acquisition device are poor due to the fact that the data reading protocol is configured in the firmware of the data acquisition device in advance is solved. By adopting the printing equipment data reading method, the data reading protocol can be automatically updated from the server according to the type of the printing equipment to be acquired, and the step of configuring the data reading protocol for the data acquisition device when the data acquisition device is installed is omitted, so that the installation cost of the data acquisition device is reduced.
It should be noted that, in the present embodiment, the data reading method of the printing apparatus of the present embodiment is described by taking the data acquisition device as an example, but the data reading method of the printing apparatus provided in the present embodiment is not limited to be applied to the data acquisition device, and may be applied to other apparatuses that need to acquire data of the printing apparatus.
In addition, through the steps, the data reading protocols of all the data acquisition devices are updated through the server, when the data reading protocol of the printing equipment of a certain model is updated, the data reading protocols of all the data acquisition devices connected with the printing equipment of the model can be updated only by updating the corresponding data reading protocol at the server, and the management cost is reduced.
Table 1 lists some of the information on the conventional OIDs. Since the parameters stored in the key values of the common OIDs are mostly fixed, for example, the printing apparatus model information is fixedly stored in the key value of the OID named 1.3.6.1.2.1.1.1.0. Therefore, in the above step S101, the data acquisition device may read the key value of the preset object identifier OID of the printing apparatus using the GET method or the WALK method of the Simple Network Management Protocol (SNMP), where the key value of the preset OID includes the model information of the printing apparatus, for example, the preset OID is the OID named as. 1.3.6.1.2.1.1.1.0; the data acquisition device can determine the model information of the printing equipment according to the key value of the preset OID.
TABLE 1 OID commonly used in SNMP
Additionally, in some embodiments, model information of the printing device may also be obtained in a user-configured manner. For example, a user configures the model information of the printing device in a management interface by accessing the management interface of the data acquisition device, and after the data acquisition device receives the configuration information including the model information, the data acquisition device determines the model information of the printing device according to the configuration information. The mode can be used as a reservation means, and the situation that the printing equipment manufacturer cannot automatically acquire the model information of the printing equipment due to the fact that the common OID is changed is avoided.
The MIB which is used as the data reading protocol records the corresponding relationship between the OID and the parameter information of the printing device, so that if the MIB is not available, the data acquisition device cannot know which parameter the key value of the read OID represents, but the absence of the MIB does not affect the data acquisition device to read the key value of some specific OIDs. Based on the method, the data acquisition device can read the key values of a plurality of preset OIDs of the printing equipment by using a Simple Network Management Protocol (SNMP) under the condition of no MIB library; the data acquisition device sends the key values of the OIDs to the server; the server matches the model information of the printing device in the MIB stored therein one by one according to the attributes or characteristics of the key values (e.g., whether the key value is a numeric value or a character, a range and a representation form of the numeric value, etc.). If the attributes or characteristics of the key values of the MIB base and the OIDs are matched to be consistent, the MIB base is considered to be needed by the data acquisition device, and the service end sends the MIB base to the data acquisition device, so that the automatic issuing of the data reading protocol is realized.
In one embodiment, the server maintains model information for all known printing devices and their corresponding data reading protocols. In step S102, the data acquisition device serving as the requester sends data reading protocol request information to the server according to the model information; after receiving the data reading protocol request information sent by the data acquisition device, the server searches a data reading protocol corresponding to the model information from a data reading protocol database according to the model information carried in the data reading protocol request information; and under the condition that the data reading protocol corresponding to the model information is found, the server side sends the data reading protocol to the data acquisition device. The data reading protocol of the data acquisition device is acquired in the mode.
It should be noted that the data collection device may be configured to request a data reading protocol from the server before data of the printing device needs to be read each time, but this way may cause frequent data interaction between the data collection device and the server. In order to avoid frequent data interaction between the data acquisition device and the server, the data acquisition device may periodically request a data reading protocol from the server, or the server may periodically push the data reading protocol to the data acquisition device. Preferably, the data acquisition device may attempt to acquire data from the printing apparatus according to a current data reading protocol, determine whether the acquired data is a correct parameter according to characteristics such as a type or a numerical range of the acquired data, and re-read the data through the steps S101 to S103 if the acquired data is not the correct parameter. Preferably, the data acquisition device may further read the model information of the printing device, and determine whether the model information of the printing device is the same as the model information corresponding to the current data reading protocol, and if so, update the data reading protocol through the steps S101 to S102.
In one embodiment, after the server receives the model information of the printing device, if the server does not find the data reading protocol corresponding to the model information in the data reading protocol database, it indicates that the server does not have the data reading protocol of the printing device of the model, and in this case, the server can record the model information and send a reminding message to the maintenance personnel to allow the maintenance personnel to find the problem in time, and add the data reading protocol corresponding to the printing device of the model in the data reading protocol database of the server in time.
In this embodiment, the data reading protocol includes: and managing an information base MIB base. In addition, the data read protocol may include a command specification to read data.
In this embodiment, the data acquisition device reads the data of the printing apparatus according to a data reading protocol, and the data acquisition device includes: the data acquisition device determines an object identifier OID to be read corresponding to the data to be read according to the MIB; the data acquisition device reads the key values of the OIDs to be read of the printing equipment by using a GET method or a WALK method of a simple network management protocol SNMP, wherein the key values of the OIDs to be read comprise the data to be read.
Fig. 2 is a schematic diagram of a data acquisition process of the data acquisition device according to an embodiment of the present invention, as shown in fig. 2, after obtaining model information of the printing apparatus 22, the data acquisition device 20 first sends the model information to the server 21 through the data upload link, and the server 21 issues a corresponding data reading protocol to the data acquisition device 20 according to the model information. After receiving the data reading protocol, the data acquisition device 20 initiates a protocol reading command according to the data reading protocol to acquire protocol data from the printing apparatus, so as to realize data acquisition. Each time compatibility with a new model of printing device needs to be added, only a new data reading protocol needs to be entered in the server 21. By the mode, a new printing equipment data reading protocol can be conveniently expanded, the new data reading protocol is added to the server at any time, the data reading protocol is acquired from the server when the data acquisition device 20 needs to be used, and frequent version upgrading and version management are reduced. The mode of managing the data reading protocol at the server also solves the problems that the factory configuration of the data acquisition device is not uniform and the targeted stock is difficult.
