Detailed Description
The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
In order to solve the technical problems that the production time of the dynamic password lock device, the shortage of production human resources and the like reduce the production efficiency in the conventional manner in order to distinguish a plurality of same dynamic password lock devices accessed to the same PC, the embodiment provides a processing method for accessing the same device, as shown in fig. 1, the method includes:
101. when determining to access a plurality of same dynamic password lock devices according to the PID and VID corresponding to the dynamic password lock devices, respectively configuring the index identifications corresponding to the plurality of same dynamic password lock devices.
Wherein the index identifications of the configurations differ from one another to distinguish the same dynamic password lock devices. For example, if it is determined through searching that the PIDs and VIDs of two dynamic password lock devices are the same, it indicates that the PC currently accesses two identical dynamic password lock devices, and then configures the index identifiers, specifically D0, D1, corresponding to the two identical dynamic password lock devices, respectively.
The execution subject for the embodiment may be an auxiliary device or an apparatus for supporting the access of the same dynamic password lock apparatus to the PC, and may be specifically configured on the PC side. The dynamic password lock device in this embodiment may be a device that performs dynamic encryption to ensure security of a link before adding money, and the work flow includes: the staff verifies on the dynamic password lock equipment, after the verification succeeds, the background system server can generate a dynamic password and send the dynamic password to the dynamic password lock equipment, the dynamic password lock equipment judges whether the dynamic password is correct, and the dynamic password lock can be opened only when the dynamic password is correct.
102. And starting a plurality of same dynamic password lock devices, and distinguishing the same dynamic password lock devices by using the index identifiers to perform data communication.
For example, the data requested by the dynamic password lock device is forwarded to the server, and the index identifier of the dynamic password lock device sending the requested data is recorded; and after the request result data are obtained, forwarding the request result data to corresponding dynamic password lock equipment according to the recorded index identifier.
For this embodiment, when only one dynamic password lock device is accessed, data communication with the PC can be implemented by identifying the PID and VID of the access device; in addition, the following situation may exist that the dynamic password lock devices with the same PID and VID are accessed, and further, in order to better distinguish and avoid the index configuration error, the index identifier is allocated when the dynamic password lock device is accessed first, and then, if the devices with the same PID and VID are accessed again, the index identifier is accumulated on the basis of the index identifier.
The method provided by this embodiment can distinguish multiple same dynamic password lock devices that are accessed by using index identifiers that are respectively configured, thereby implementing a communication mechanism that enables the same dynamic password lock devices to be free from interference. Compared with the conventional mode, the PID and VID of the equipment or the descriptor of the equipment do not need to be distinguished by burning different firmware for each dynamic coded lock when the dynamic coded lock equipment is produced, the production time is not additionally prolonged, the labor cost is saved, and the production efficiency is improved.
Further, as a refinement and an extension of the specific implementation of the foregoing embodiment, in order to fully describe the implementation process of the present embodiment, another processing method for accessing the same device is provided, as shown in fig. 2, the method includes:
201. and searching the dynamic password lock equipment with the same PID and VID when determining to access a plurality of same dynamic password lock equipment according to the corresponding PID and VID of the dynamic password lock equipment.
202. And according to the sequence of the search results, accumulating and configuring the index identifications corresponding to the searched dynamic coded lock devices with the same PID and VID.
For example, a first dynamic password lock device searched under the condition that the PID and VID are the same is used as an index 0 device, and a corresponding index identifier D0 is configured; the second searched dynamic password lock device is used as an index 1 device, and a corresponding index identifier D1 is configured; the third searched dynamic password lock device is used as an index 2 device and is configured with corresponding index identifications D2 \8230, 8230and so on, all the dynamic password lock devices with the same PID and VID are searched out and are configured with corresponding index identifications respectively, and the index identifications are different from one another so as to be distinguished. And if the newly added dynamic password lock equipment with the same PID and VID exists, continuously accumulating the index identification according to the accumulated index identification to be used as the index identification corresponding to the newly added dynamic password lock equipment. By the method, each dynamic coded lock device with the same PID and VID can be accurately configured with the corresponding index identification, and the index identifications are different.
203. And starting a plurality of same dynamic password lock devices, and configuring device description names corresponding to the same dynamic password lock devices.
The same dynamic coded lock equipment accessed to different USB interfaces has different corresponding equipment description names.
For example, when multiple dynamic password lock devices are accessed at different USB interfaces, their respective corresponding configured device description names are different and may be randomly changed.
204. And distinguishing a plurality of same dynamic password lock devices for data communication by using the configured index identification and the device description name.
In this embodiment, for the same dynamic password lock device, because the index identifier and the device description name configured for each device are different, the index identifier and the device description name are combined for distinguishing, so that the same dynamic password lock device can be better identified, the identification accuracy is improved, and accurate data communication between the same dynamic password lock device and the server is ensured. The condition that the identification accuracy is influenced due to the fact that abnormity occurs when the index identification or the equipment description name is singly used for distinguishing can be avoided. Optionally, in addition to the manner of distinguishing by combining the index identifier and the device description name, the method may further distinguish by matching with a corresponding timestamp when the device accesses, and if the device accesses non-simultaneously, the access timestamps are different, so that the identification accuracy of the same dynamic password lock device may be further improved by the optional manner.
In the subsequent work of the dynamic password lock devices which are connected and started, the situation of disconnection in midway (such as manual plugging and unplugging, abnormal disconnection and the like) sometimes exists, and for the same dynamic password lock device, if the dynamic password lock devices are disconnected, the specific disconnected devices in the same dynamic password lock device cannot be judged in time because the dynamic password lock devices have the same PID and VID. At present, the traditional mode adopts the same plug and the same plug, for example, two same dynamic password lock devices, if one device is disconnected, the bus is unplugged, at the moment, the two devices are disconnected, then the bus is plugged again to restart the two devices, so as to ensure the normal operation of the two devices, however, the mode can influence the data communication of the connected devices.
Therefore, in order to identify the disconnected device in time and avoid the above problem, further, as an optional manner, the method of this embodiment may further include: respectively configuring device variable values for dynamic password lock devices corresponding to the index identifiers, starting threads for reading HID data of human interface devices, and monitoring whether the dynamic password lock devices corresponding to the index identifiers are online or not (if one thread is respectively started for each same device for monitoring, the targeted monitoring mode can improve the timeliness and accuracy of monitoring), wherein the corresponding device variable values are emptied when the dynamic password lock devices are disconnected; for example, a device variable value (e.g., K values such as K0, K1, and K2) may be allocated to each dynamic password lock device, and the device variable value corresponding to the device may be cleared when the device is disconnected, so that the thread reading the HID data is used to monitor the device variable value corresponding to the device variable value, and then whether the device variable value is cleared is determined to monitor whether the corresponding dynamic password lock device is online.
And if the condition that the equipment is disconnected is monitored, determining the dynamic password lock equipment disconnected by a plurality of same dynamic password lock equipment according to the emptied equipment variable value. By the mode, the disconnected dynamic password lock equipment can be timely identified when the equipment is disconnected, if conditions allow the equipment to be singly reconnected, different equipment can be respectively controlled, all the equipment cannot be restarted due to the fact that one equipment is disconnected, and management and labor division of the dynamic password lock equipment are more flexible.
For example, dynamic combination lock devices are used to encrypt cassettes to ensure the security of cassette usage. In a specific application, the banknote boxes are divided into different banknote boxes according to the currency amount, each dynamic password lock device controls the banknote boxes with different currency types respectively, and devices with the same PID and VID may exist in the dynamic password lock devices. By applying the method provided by the embodiment, one PC can simultaneously support access to a plurality of same dynamic password lock devices and maintain data communication. Therefore, only the target money box needing to be maintained can be opened during money adding, and the background can also identify the information of the target money box to be maintained. And other paper money boxes can not be broken, and data communication with the PC can be continuously kept.
If the thread monitoring device is started to monitor that the existing device is disconnected, further, in order to accurately distinguish when the subsequent device is reconnected, the method of this embodiment may further include: and after the disconnected dynamic password lock device is reconnected, searching the dynamic password lock devices with the same PID and VID again, and reconfiguring the index identifications and the device description names corresponding to the dynamic password lock devices with the same PID and VID.
For example, if the number of the dynamic password lock devices with the same PID and VID is two, after the disconnected dynamic password lock device is reconnected, the re-searching for the dynamic password lock device with the same PID and VID and re-configuring the index identifier and the device description name corresponding to each of the dynamic password lock devices with the same PID and VID may specifically include: if the disconnected dynamic coded lock device is a second searched dynamic coded lock device when two dynamic coded lock devices with the same PID and VID are accessed last time, in the process of searching the two dynamic coded lock devices again, the temporary device description name is saved when the dynamic coded lock devices are searched for the first time; when the dynamic password lock equipment is searched for the second time, comparing a first target equipment description name configured to the dynamic password lock equipment searched for the second time with a second target equipment description name configured to the dynamic password lock equipment searched for the first time when the two dynamic password lock equipment are accessed last time, wherein the temporary equipment description name is different from the first target equipment description name; if the first target device description name is the same as the second target device description name, the temporary device description name is configured to the current second searched dynamic password lock device instead of the first target device description name; and if the first target device description name is different from the second target device description name, determining to configure the first target device description name to the current second searched dynamic password lock device.
When the dynamic password lock device is disconnected and reconnected, since the newly connected USB port of the disconnected and reconnected device is different from the previously connected USB port, it is possible to identify the devices with the same index identifier when the dynamic password lock devices with the same PID and VID are searched again, thereby causing data communication errors. For example, there are 4 USB ports, port No. 1 to port No. 4, for a PC; for both dynamic password lock device 1 and device 2 of the same PID and VID, first device 1 is accessed to port No. 2 and device 2 is accessed to port No. 3. When searching is performed by the method of the embodiment, according to the sequence from small to large of field values in device description names correspondingly generated when devices are accessed to the USB ports (different USB ports are accessed and randomly changed), the device 1 is searched first, and then the device 2 is searched. Correspondingly, the index identifier corresponding to the configuration device 1 is a D0 device, and the index identifier corresponding to the configuration device 2 is a D1 device; and if the D1 device is disconnected and then the port 1 is reconnected, searching according to the sequence from small to large of the field values corresponding to the USB ports accessed by the device when the device is searched again. If the field value corresponding to the USB port to which the D1 device is connected is smaller than the field value corresponding to the USB port to which the D0 device is connected, the system may determine that the newly connected device is also the D0 device, however, in order to ensure data communication of the original D0 device, the index identifier and the device description name of the original D0 device are still retained, which is equivalent to that there are two D0 devices at this time, and the system may not distinguish the two D0 devices, which may cause a data communication error.
In order to solve the above problem, the above configuration manner according to this embodiment specifically includes: when the D1 device is disconnected and reconnected, a temporary device description name may be saved when the device is searched for the first time, then when the device is searched for the second time, the device description name a generated corresponding to the "new D1 device" is compared with the device description name B generated corresponding to the original D0 device when the device is accessed, if a is the same as B, the "new D1 device" is the original D0 device, and at this time, the device description name a is also given to the "new D1 device", which may result in the system finally searching and configuring to obtain two D0 devices (since the original D0 device is not disconnected, the index identifier and the device description name thereof are still retained), so in order to distinguish, the temporary device description name is given to the "new D1 device", and since the temporary device description name is different from the device description names a and B, the occurrence of a situation that the system finally searches and configures to obtain two D0 devices may be avoided. If A is different from B, which is equivalent to a new D1 device, and the original D0 device are different, the purpose of distinguishing can be achieved by giving the device description name A to the new D1 device.
Through the configuration mode, the problem can be prevented from occurring, and the same dynamic password lock equipment can be accurately distinguished subsequently. Therefore, different devices can be controlled respectively, all the devices cannot be restarted due to the fact that one device is disconnected, and management and labor division of the dynamic coded lock device are more flexible.
Further optionally, in order to meet more service requirements and improve the accuracy of subsequently distinguishing the same dynamic password lock device, the index identifier may further include a group characteristic, where the group characteristic is used to determine a device type corresponding to the same dynamic password lock device, and correspondingly, the method in this embodiment may further include: if the dynamic password lock equipment is newly accessed, detecting whether the newly accessed dynamic password lock equipment and a plurality of accessed same dynamic password lock equipment have the same PID and VID; if the newly accessed dynamic password lock device and a plurality of accessed same dynamic password lock devices have the same PID and VID, configuring a corresponding target index identifier for the newly accessed dynamic password lock device, wherein the target index identifier is different from the index identifiers corresponding to the same dynamic password lock devices and comprises the same group characteristics.
In this alternative, the device types may be divided according to actual requirements. For example, if there are 5 dynamic password lock devices having the same PID and VID and divided into two groups a and B (e.g., each group corresponds to a different maintenance unit, and each device is labeled with an identifier of its corresponding maintenance unit), when searching and configuring its corresponding index identifier, the corresponding index identifiers are sequentially configured as A1, B2, B3, A4, and B5 according to the search order and the labeled maintenance unit identifiers. Here, the maintenance units of the group a corresponding to the 1 st and 4 th searched devices are explained, and the maintenance units of the group B corresponding to the remaining 3 searched devices are explained. By recording the device data communication log in the mode, which group of devices are abnormal, specifically which device in the group and the like can be found out accurately from the same dynamic password lock devices according to the log. If the device with the same PID and VID is accessed newly, the corresponding index identification can be configured according to the maintenance unit identification marked by the new access device, for example, the index identification can be configured to be A6 when the maintenance unit corresponding to the group A is accessed.
Based on the above description, to further explain the specific implementation process of the above embodiment, taking the example of accessing two identical dynamic password lock devices to a PC, the following application scenarios are given, but not limited thereto:
in order to implement the distinction between two identical dynamic-password-locked devices accessed on the same PC, a device-initiated connection mechanism is first established, which is intended to prepare for reconnection and communication. The method specifically comprises the following steps:
(1) The first dynamic password lock device searched out under the condition that PID and VID are the same is used as an index 0 device (called D0);
(2) A second dynamic password lock device searched out under the condition that the PID and the VID are the same is used as an index 1 device (called D1);
(3) If the device D0 exists, starting the D0, and saving the device description name by using a variable I0 (such as:;
(4) If the device D1 exists in the search result, the device D1 is started, and a variable I1 is used for saving the device to obtain a device description name (such as:, \ \ hid # vid _046D &pid \ c31c &mi00 &7 &b4f3ed2&0&0000# {4D1e55b2-f16f-11cf-88cb-001111000030 });
(5) Two dynamic password lock HID devices, of which "#7&11e158f &0&0000#", "#7&b4f3ed2&0&0000#", are identical and randomly change when different USB ports are accessed, of the two values of (3) and (4) above. It should be noted that, when re-accessing, the D0 device may become the D1 device, the D1 device may also become the D0 device, and it should be considered that only the D0 device is provided when only one dynamic password lock device is accessed.
For example, before the D0 device and the D1 device are not disconnected, field values in device description names correspondingly generated by accessing the USB port are "#7&11e158f &0&0000#", "#7&b4f3ed2&0&0000#", respectively, where "11" in the first field value is smaller than "b4" in the second field value. When the D0 device is disconnected and then re-accesses an interface different from the previously inserted USB interface, a field value in a newly generated device description name is "#7&b6e158f &0&0000#", and then after the system re-search is performed according to the sequence of the field values from small to large, "b6" is greater than "b4", the original D1 device becomes the D0 device, and the original D0 device becomes the D1 device; or when the D1 device is disconnected and then re-accesses an interface different from the previously inserted USB interface, and the corresponding field value is "#7 &09158f &0&0000#", after the system re-search, the original D0 device becomes the D1 device, and the original D1 device becomes the D0 device.
In view of the above, a mechanism for disconnection processing reconnection is established with the object of preventing communication errors caused by the PC system reassigning indexes in order to disconnect processing reconnection. The method specifically comprises the following steps:
(a) Starting a thread for reading HID data to monitor whether the D0 equipment is on line or not;
(b) Starting a thread for reading HID data to monitor whether the D1 equipment is on line or not;
(c) And (3) monitoring that the equipment is disconnected, adopting an object-oriented processing mode, allocating an equipment variable K value (K0, K1) to each connected object, emptying the corresponding K0 and K1 variables when the connected object is disconnected, synchronously comparing and emptying the corresponding I0 and I1 together correspondingly (if the D0 equipment is disconnected when the K0 is emptied, the corresponding I0 is also emptied together), returning to the step (3) again to perform connection processing, and judging whether the disconnected object is D1. If the device is disconnected, a variable TEMP is stored when the device is searched for the first time, which is used for storing a temporary device description name, two identical devices search a second result, and the device description name a corresponding to the current D1 in the second result is compared with the device description name B corresponding to the I0 obtained in the above (3), if the two identical devices are identical, it is indicated that the current D1 device is the original D0 device, and at this time, the device description name a is also given to the current D1 device, which may cause the system to finally search and configure to obtain two D0 devices (since the original D0 device is not disconnected, the index identifier and the device description name thereof are still retained), so the temporary device description name stored by the TEMP is given to the current D1, and since the temporary device description name is different from the device description names a and B, the occurrence of the situation that the system finally searches and configures to obtain two D0 devices can be avoided. If A is different from B, which means that the current D1 device is different from the original D0 device, the purpose of distinguishing can be achieved by giving the device description name A to the current D1 device.
If the disconnection is D0, after two searches, when the device is searched for the second time, a variable TEMP is saved for saving the temporary device description name. The device description name C corresponding to the current D0 in the first result is compared with the device description name D corresponding to the I1 obtained in (4), if the two device description names are the same, it is indicated that the current D0 device is the original D1 device, and at this time, the device description name C is also given to the current D0 device, which may cause the system to finally search and configure to obtain two D1 devices (since the original D1 device is not disconnected, the index identifier and the device description name thereof are still retained), so the temporary device description name stored in the TEMP is given to the current D0, and since the temporary device description name is different from the device description names C and D, the occurrence of a situation that the system finally searches and configures to obtain two D1 devices may be avoided. If C is different from D, which is equivalent to that the current D0 device is different from the original D1 device, the purpose of distinguishing can be achieved by giving the device description name C to the current D0 device.
And finally, establishing a communication mechanism, wherein the purpose is to achieve the purpose of achieving the communication mechanism that two same dynamic password lock devices do not interfere with each other. It should be noted that the communication mechanism needs to be executed after the devices start the connection mechanisms (1) to (5) and the disconnection processing reconnection mechanisms (a) to (c) are established. As shown in fig. 3, specifically, when sending data, the client supports multithread transceiving, and then forwards the upload data of the dynamic password lock device to the server; the message replied by the server side is replied to the corresponding dynamic password lock through the indexes I0 and I1 of the client side, so that the message sending error can be effectively prevented, and the condition of serial connection of the messages can not occur.
