Usually, a plurality of inspection devices of different manufacturers appear at the same time, and unified centralized management control is difficult to realize.

For the analytical instruments of the same manufacturer, because the communication standards are consistent, the unified management control can be conveniently performed through intermediate software, for example, the real-time state of the sample on each analytical module is monitored, but some operations still need to be performed on terminal equipment.
For instruments of different brands, basic communication can be set, even bidirectional communication with intermediate software is not realized, the actual effect of automatic informatization is greatly reduced, and most operations still need to be carried out on terminal equipment.
For manufacturers who integrate different manufacturers into a single brand through acquisition, because of different design concepts of original equipment, the modes of managing samples are different, actually, the different operation systems are still used, and some operations still need to be operated on terminal equipment.

Fig. 1 shows a method for specifically performing management and control after the centralized management and control system in a medical laboratory is adopted, which specifically comprises the following steps:
step S101, a service module of a medical laboratory instrument terminal receives a control request sent by a central monitoring area control terminal through a monitoring module, wherein the control request comprises operation information for control.
The service module is provided with software or hardware for executing corresponding software; the service module is used for executing registration and binding with the corresponding instrument terminal, and the specific method comprises the steps of obtaining a unique mark of the instrument terminal, judging whether the mark is consistent with a record recorded during registration when the service module is started, and avoiding instrument experiment information leakage caused by the fact that the service module is not corresponding to the instrument terminal. The service module needs to set the name of the instrument terminal, the connection key, the network address IP, and the communication port.
The control terminal located in the central monitoring area of the medical laboratory is provided with a monitoring module, and the monitoring module is provided with software of a service module or hardware capable of executing corresponding software. The monitoring module needs to perform registration and is bound with the corresponding control terminal, and the specific method comprises the steps of obtaining a unique mark of the control terminal, judging whether the mark is consistent with a record recorded during registration when the monitoring module is started, and avoiding instrument experiment information leakage caused by the fact that the monitoring module is not corresponding to the control terminal. The registration information of the monitoring module and the registration information of the service module are distinguished, and the confusion of the function authorities of the monitoring module and the service module is avoided. The registration information includes: the method comprises the following steps that a unique mark of a control terminal, a module type, registration time, a registration mechanism, a system serial number and a registration code are marked; the monitoring module and the service module are automatically deployed after the registration information is verified successfully, and are adapted to the equipment, wherein the deploying comprises equipment binding, environment building, drive installation and the like;
the monitoring module is responsible for recording operation information executed by a user on the control terminal, and after the monitoring module is in communication connection with the service module, when the monitoring module sends a control request to the service module, the monitoring module encrypts the operation information data and transmits the encrypted operation information data to the service module. The operation information firstly comprises the security verification information of the service module: network address IP, communication port, connection key. The operation information to be recorded secondly may include, but is not limited to: mouse operation information, keyboard operation information and code scanner operation information; the last operation information further includes screen acquisition information: image data information, the number of screens, the size of each screen and heartbeat packet information keeping links;
the mode of establishing communication connection between the monitoring module and the service module is as follows: the safety certification is to upgrade the VNC protocol certification, the user password has no length limitation, the protocol data is sent by using a ciphertext, the server sends a random number verification of 16 bytes to the client, the monitoring module adopts asymmetric encryption for verification, a secret key is generated according to the user password and is replied to the service module by 16 bytes, and at this time, the service module adopts the same asymmetric encryption algorithm to return a safety result to the monitoring module; if successful, entering into the initial message stage, and if not, closing the connection.
Since the general VNC security authentication is sent in plaintext and is easily obtained by other illegal users, encryption processing of a key is added when the monitoring module and the service module establish communication connection in this embodiment, the monitoring module and the service module respectively encrypt using the same algorithm in this embodiment using an asymmetric encryption manner, and therefore the monitoring module in this embodiment can only connect with the service module having the same algorithm.
And step S102, the service module of the instrument terminal analyzes the operation information from the received control request, executes the operation corresponding to the operation information and returns the operation execution result to the monitoring module. The specific operation is as follows:
when the service module receives the security information request, the security information is verified;
when the service module receives the screen acquisition information request, the service module acquires the number of screens of the instrument terminal equipment and the size of each screen and returns the number of the screens and the size of each screen to the monitoring module, and the monitoring module analyzes desktop image data returned by the service module according to the screen selected by the user and extracts corresponding image data to display the image data in the display area.
As shown in fig. 5, two screens of the terminal device 1 are displayed in S201 and S202, respectively; the service module performs equal-ratio scaling on the image according to the image scaling contained in the operation information and then returns the image, so that the communication data flow is reduced, and the communication speed is increased.
Step S103, the monitoring module performs centralized display on the display interfaces of the instrument terminals by using a graphic algorithm through the equipment management function, and the selected equipment can be controlled by switching the full screen; after the operation execution result is returned to the monitoring module, the monitoring module executes the following operations:
as shown in fig. 5, the monitoring module performs image analysis according to the data information sent by the service module, performs image presentation according to the number of screens and the size of the screens, and selects the display number of each page according to the number of screens; as shown in fig. 5, S207 is set to 6, and then six terminal interface display windows of S201, S202, S203, S204, S205, and S206 are presented in the display area; wherein the six terminal interface images are automatically scaled to a suitable size for display.
When the S209 connection function is executed, the monitoring module performs sequential connection on all terminals of the current page, where connection is not repeated for already connected terminal devices; when the monitoring module is started, the terminal connected last time can be automatically reconnected.
When the full screen function of S201 is executed, the interface shown in fig. 7 is entered, and at this time, the first terminal may be remotely controlled, and the specific operation mode is as follows: the monitoring end records mouse and keyboard action information, including mouse position information, key value information and key state information; keyboard key values and key states; motion information such as a bar code scanner or a handwriting board; and transmitting the data to a service module, and executing corresponding operations by the service module, such as: simulating the mouse operation to move to the position of the mouse subjected to resolution conversion in the operation information; simulating operation according to states corresponding to the mouse key values; processing the keys according to system requirements, and matching corresponding relations between the equipment keys and key values of the operation information keyboard; simulating a key state change operation corresponding to the key; performing a scanner generated operation; and executing the operation of the handwriting pad.
