This is the objective requirement for the monitoring and operation of instruments and equipment in the CDC environment. In addition, due to the large number of imported instruments and equipment, it is difficult to provide equipment interfaces for automated operation and maintenance. Summary of the invention

[0014] If the risk factor is less than the minimum value of the preset threshold range, it is marked as equipment cold operation.

[0015] In some embodiments, the calculation formula of the risk factor is as follows:

[0016]

[0017] Among them, X k represents the risk factor of the kth device, i represents the device type, V k Represents the voltage value of the kth device, A k represents the current value of the kth device, T k represents the temperature value of the kth device, H k Represents the humidity value of the kth device, V 1,ref Indicates the voltage reference value of the first type of equipment, A 1,ref Indicates the current reference value of the first type of equipment, T 1,ref Indicates the temperature reference value of the first type of equipment, H 1,ref Indicates the humidity reference value of the first type of equipment, V 2,ref Indicates the voltage reference value of the second type of equipment, A 2,ref Indicates the current reference value of the second type of equipment, T 2,ref Indicates the temperature reference value of the second type of equipment, H 2,ref Indicates the humidity reference value for type 1 equipment.

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] It should be noted that, for the convenience of description, only the parts related to the relevant invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

However, if other words can achieve the same purpose, the word can be replaced by other expressions.

[0040] Unless the context clearly indicates an exception, the words "a", "an", "a kind" and / or "the" do not refer to the singular, but also include the plural.

[0042] In addition, flow charts are used in the present application to illustrate the operations performed by the system according to the embodiments of the present application. It should be understood that the preceding or following operations are not necessarily performed accurately in order. On the contrary, the various steps may be processed in reverse order or simultaneously. At the same time, other operations may also be added to these processes, or a certain step or several steps of operations may be removed from these processes.

[0043] Reference Figure 1 , is a flow chart of an optional example of a device status monitoring method proposed in the present invention. The method can be applied to computer devices. The monitoring method proposed in this embodiment may include but is not limited to the following steps:

[0044] Step S1, defining monitoring regulations of equipment, and collecting monitoring information of the equipment according to the monitoring regulations;

[0045] The monitoring regulations include interface protocols, specifications, data formats, content, frequency and device types. Device types are divided according to the characteristics of the devices, which can be divided according to the degree of importance or the sensitivity of parameter values. Interface protocols are defined according to different device types / transmission methods.

[0046] Step S2, transmitting the monitoring information to a database;

[0047] Step S3, calculating the risk factor according to the monitoring information, analyzing it in combination with the preset threshold interval, and generating a determination report;

[0048] Step S4: display the determination report and the monitoring information.

[0049] The present invention obtains the current and voltage data of the instrument equipment / power supply cable through a passive sensing device; the monitoring system judges the equipment operation status and whether there is a fault based on the sensed equipment operation current and voltage data combined with historical data analysis; in addition, the passive sensing device has the ability to disconnect the power supply of the instrument equipment in an emergency, and can stop the operation of the instrument equipment in an emergency.

[0050] In some feasible embodiments, the step S2 specifically includes:

[0051] S2.1, saving the monitoring information in a chain format;

[0052] S2.2, uploading the monitoring information to the database in a chain manner.

[0053] In this case, data elements are stored in a set of arbitrary storage units, and additional pointers represent the logical relationship between data elements. The chain structure can make full use of computer memory space and realize flexible memory dynamic management.

[0054] In some feasible embodiments, the step S3 specifically includes:

[0055] S3.1. Calculate the risk factor based on the voltage, current, temperature and humidity in the monitoring information;

[0056] S3.2. Compare the risk factor with the preset threshold interval; if the risk factor is greater than the maximum value of the preset threshold interval, mark it as hot operation of the equipment; if the risk factor is within the preset threshold interval, mark it as normal operation of the equipment; if the risk factor is less than the minimum value of the preset threshold interval, mark it as cold operation of the equipment.

[0057] The calculation formula of the risk factor is as follows:

[0058]

[0059] Among them, X k represents the risk factor of the kth device, i represents the device type, V k Represents the voltage value of the kth device, A k represents the current value of the kth device, T k represents the temperature value of the kth device, H k Represents the humidity value of the kth device, V 1,ref Indicates the voltage reference value of the first type of equipment, A1,ref Indicates the current reference value of the first type of equipment, T 1,ref Indicates the temperature reference value of the first type of equipment, H 1,ref Indicates the humidity reference value of the first type of equipment, V 2,ref Indicates the voltage reference value of the second type of equipment, A 2,ref Indicates the current reference value of the second type of equipment, T 2,ref Indicates the temperature reference value of the second type of equipment, H 2,ref Indicates the humidity reference value for type 1 equipment.

[0060] According to the defined equipment, the equipment is divided into electrical parameter sensitive type or environmental parameter sensitive type, and the risk coefficient calculation formula with different weights is constructed according to this type. This makes the calculation of the coefficient more reasonable, and thus makes the judgment of the abnormal state of the equipment more targeted.

[0061] In some feasible embodiments, it also includes:

[0062] According to different equipment types, a multiplication factor is introduced to adjust the preset threshold range.

[0063] Wherein, the multiplication factor expression is as follows:

[0064]

[0065] The multiplier factor is set according to different equipment types. For equipment with lower importance, the threshold range can be expanded. For equipment with higher importance, the threshold range is strictly controlled, making the monitoring and comparison system more suitable for different scenarios.

[0066] In some feasible embodiments, the step of displaying the determination report and the monitoring information specifically includes:

[0067] S4.1. When the equipment is marked as hot running in the judgment report, a red signal warning is issued;

[0068] S4.2. When the equipment is marked as cold operation in the judgment report, a blue signal warning is issued;

[0069] S4.3. The voltage, current, temperature and humidity in the monitoring information are associated with corresponding devices and displayed.

[0070] Associating specific content with devices one by one and displaying them on the platform can help operation and maintenance personnel view and locate devices in real time.

[0071] In some feasible embodiments, it also includes:

[0072] The monitoring information is screened and cleaned.
