The existing laboratory management usually needs manual processing, most of management equipment operates independently, unified information management is not performed by a unified server, and the management efficiency is low. Meanwhile, the existing laboratory management equipment cannot control the starting and stopping of the experimental equipment based on the running state of the experimental equipment and the identity verification result of the experimental personnel, and the safety of the experimental personnel and the equipment cannot be guaranteed simultaneously. In order to solve the above problem, the first embodiment of the present invention provides an experimental facility management and control system 10.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an experimental facility management and control system according to a first embodiment of the present invention.

The experimental facility management and control system 10 includes a sensing module 11, an authentication terminal 12, and a server 13. The server 13 is in communication connection with the sensing module 11 and the authentication terminal 12, respectively.

The experimental equipment management and control system 10 in this embodiment may be established for a college laboratory, a research and development unit laboratory, or other laboratories that need to perform safety management and control on experimental equipment, and the experimental equipment for the management and control system may be electronic equipment with higher requirements on safety, such as a mainframe computer, a mainframe server, a numerical control machine, and a lithography machine.

It should be understood that, in other embodiments, the experimental device management and control system 10 may also be used for the non-electronic devices, for the anti-theft of the non-electronic devices, and for the authentication of the experimenters, so as to improve the experimental security of the non-electronic devices.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a sensing module according to a first embodiment of the present invention.

The sensing module 11 includes a current sensor 111 and a voltage sensor 112 provided on each experimental device. The current sensor 111 and the voltage sensor 112 can be directly connected with an operation circuit of the experimental equipment to directly monitor the instant operation current and voltage of the experimental equipment, so that the real-time monitoring of the experimental equipment is realized; on the other hand, the current sensor 111 and the voltage sensor 112 can also be installed at the power supply of the experimental equipment, and the installation mode does not need to integrate and install the current sensor 111 and the voltage sensor 112 into the running circuit of the experimental equipment, so that the installation mode is convenient and fast, and the running state of the experimental equipment can be monitored from the power supply.

The current sensor is different according to the measurement principle, and can be mainly divided into: shunts, electromagnetic current transformers, electronic current transformers, and the like. The electronic current transformer includes a hall current sensor, a rogowski current sensor, and an AnyWay variable frequency power sensor (which can be used for voltage, current, and power measurement) dedicated to variable frequency power measurement, and the like, and compared with the electromagnetic current sensor, the electronic current transformer has no ferromagnetic saturation, a wide transmission band, a small secondary load capacity, a small size, and a light weight, and thus the current sensor 111 in this embodiment may be a hall effect sensor.

Furthermore, the hall current sensor can measure current and voltage with any waveform at the same time, and the output end of the hall current sensor can truly reflect waveform parameters of the current or voltage at the input end; has the characteristics of high precision, convenient installation and low selling price. The current sensor 111 and the voltage sensor 112 in this embodiment may therefore be integrally provided hall effect sensors.

For example, the temperature sensor 113 may be disposed at the processor and the heat sink of the electronic processing device, and may also be disposed at the power source of the experimental device, so as to determine the temperature condition of the experimental device in all directions, and avoid the situation that the experimental device is overheated and burns out, and even a safety accident occurs.

To determine the specific state of many experimental devices, the sensing module 11 may further include a posture sensor 114, considering that many experimental devices may require a experimenter to move the experimental device, such as a radio frequency signal detector which needs to move to search for signals and is vulnerable.

The attitude sensor 114 is a high-performance three-dimensional motion attitude measurement system based on MEMS (micro electro mechanical systems) technology. The attitude sensor 114 comprises a motion sensor such as a gyroscope, an accelerometer, an electronic compass and the like, obtains data such as a three-dimensional attitude, an azimuth and the like subjected to temperature compensation through an embedded low-power ARM processor, and outputs zero-drift three-dimensional attitude azimuth data represented by quaternions and Euler angles in real time by using a quaternion-based three-dimensional algorithm and a special data fusion technology. The three-dimensional attitude orientation data, i.e., attitude data, collected by the attitude sensor 114 is used to determine the motion attitude and motion direction of the experimental device. For example, the server 13 or the onboard processor of the sensing module 11 determines whether the experimental device is in a normal working state based on the received attitude data collected by the attitude sensor 114, and if not, generates the warning information.

The MEMS is an independent intelligent System, can be produced in large batch, and the System size is several millimeters or even smaller, and the internal structure of the MEMS is generally in micron or even nanometer level, for example, the size of a common MEMS product is generally 3mm × 3mm × 1.5.5 mm or even smaller, so that the MEMS adopted in the embodiment can accurately acquire attitude data of experimental equipment, and simultaneously the integrity of the experimental equipment is also ensured, and the experimental equipment does not need to be disassembled and then loaded into an electronic sensor with large volume and complex circuit.

As an alternative implementation, the sensing module 11 in this embodiment may further include a vibration sensor 115. The vibration sensor 115 is used to detect whether the numerical control machine tool or other experimental equipment is in a vibration state and the vibration intensity, so that an experimenter or a monitoring person can grasp the state of the experimental equipment vibrating in operation in real time. The vibration sensor 115 in this embodiment may be an eddy current displacement sensor capable of measuring the distance between the measured metal conductor and the probe surface in a static and dynamic non-contact, high linearity and high resolution manner, and is a non-contact linear metering tool capable of accurately measuring the static and dynamic relative displacement change between the measured body (which must be a metal conductor) and the probe end surface. The eddy current displacement sensor can continuously and accurately acquire various parameters of the vibration state of a rotor, such as radial vibration, amplitude and axial position of a shaft, of non-contact high-precision vibration and displacement signals in the state analysis, vibration research and analysis measurement of high-speed rotating machinery and reciprocating machinery, so that the eddy current displacement sensor has the advantages of good long-term working reliability, wide measurement range, high sensitivity, high resolution and the like.

Eddy current displacement sensor has integral type and split type design, and split type sensor has better measurement accuracy nature, and the integral type possesses the convenient degree of better installation. Optionally, the eddy current displacement sensor in the present embodiment is of an integrated design.

Referring to fig. 3, fig. 3 is a schematic connection diagram of a data transmission module according to a first embodiment of the present invention.

Considering that the power consumption of the sensing device of the sensing module 11 is small, the data can be uploaded by using the internet of things technology, the experimental device management and control system 10 in this embodiment may further include a data transmission module 14, the data transmission module 14 may include an internet of things submodule and a WiFi submodule, the internet of things submodule is connected with the sensing module 11 and the authentication terminal 12, and the WiFi submodule is connected with the server 13.

As an optional implementation manner, the internet of things submodule may adopt a low-power-consumption wide area internet of things communication module, the low-power-consumption wide area network is oriented to the communication requirements of long distance and low power consumption in the internet of things, and a network layer technology of the internet of things appears in recent years, and the technical characteristics of the low-power-consumption wide area network include: the transmission distance is long, the node power consumption is low, the network structure is simple, and the operation and maintenance cost is low. Optionally, the internet of things submodule in this embodiment is a ZigBee module. The ZigBee technology is a two-way wireless communication technology with short distance, low complexity, low power consumption, low speed and low cost, and is mainly used for data transmission among various electronic devices with short distance, low power consumption and low transmission speed and typical application of periodic data, intermittent data and low reaction time data transmission. Briefly, ZigBee is a highly reliable wireless data transmission network, similar to CDMA and GSM networks. The ZigBee data transmission module is similar to a mobile network base station, the communication distance is from 75m to hundreds of meters and kilometers in a standard way, and infinite extension is supported. ZigBee is a wireless data transmission network platform consisting of 65535 wireless data transmission modules, each ZigBee network data transmission module can communicate with each other in the whole network range, and the distance between each network node can be infinitely expanded from 75m of the standard. Different from CDMA network or GSM network of mobile communication, ZigBee network is mainly established for industrial field automation control data transmission, so that it must have the characteristics of simple structure, convenient use, reliable operation and low cost, at the same time, the mobile communication network is mainly established for speech communication, and the value of every base station is generally above million yuan RMB, but every ZigBee "base station" is less than 1000 yuan RMB, so that it can greatly reduce cost of communication equipment.

It should be understood that in other alternative embodiments, the internet of things submodule may also be an L oRa module or other low-power wide-area internet of things communication module.

The internet of things submodule is used for receiving the sensing data uploaded by the sensing module 11 and transmitting the sensing data to the server 13 through the WiFi submodule. Further, the present embodiment may also receive authentication information uploaded by the authentication terminal 12 through the internet of things sub-module, and transmit the authentication information to the server 13 through the WiFi sub-module.

The authentication terminal 12 includes an access control device provided on or near a laboratory door and an equipment lock provided on each experimental device.

As an optional implementation manner, the access control device in this embodiment includes an identifier and a controller, and both the identifier and the controller are in communication connection with the server. It should be understood that the device lock of the present embodiment may also be the same as the door access device, including the identifier and the controller.

Referring to fig. 4, fig. 4 is a schematic connection diagram of an identifier and a controller according to a first embodiment of the present invention.

The recognizer in this embodiment can be a biological feature recognizer, for example, an iris recognizer based on a high-definition color camera, a structured light face recognizer based on a depth camera, a common face recognizer based on a flat camera, a fingerprint recognizer, a voiceprint feature recognizer and the like, meanwhile, the recognizer can be only used for collecting biological features of experimenters, then the collected biological features are transmitted to an internet of things submodule of a data transmission module 14 through an internet of things communication mode, then the WiFi submodule of the data transmission module 14 transmits to a server 13 for identification verification of the experimenters, and whether the experimenters are legal access control personnel or legal operators of experimental equipment is judged. The server 13 sends the security information indicating whether the experimenter is a legal operator of the access control or the experimental equipment to the controller (the controller may share one internet of things data transmission module with the identifier) through the data transmission module 14, and the controller controls the start and the stop of the electronic lock of the laboratory door or the experimental equipment. Thereby improving the safety of the experimental equipment.

As an optional implementation manner, the identifier in this embodiment may also be a radio frequency reader disposed on the experimental device or connected to the electronic lock controller of the laboratory door, and the security authentication is completed when the experimenter completes matching of the radio frequency transponder (electronic tag). The radio frequency transponder and the radio frequency reader used in this embodiment are matching devices in a radio frequency identification system, and Radio Frequency Identification (RFID) is a wireless communication technology that can identify a specific target and read and write related data by radio signals without establishing mechanical or optical contact between the identification system and the specific target. The radio signal is an electromagnetic field modulated to a radio frequency to transmit data from a tag (i.e., a radio frequency transponder) attached to an article to automatically identify and track the article. Some tags can obtain energy from the electromagnetic field emitted by the identifier during identification, and do not need a battery; there are also tags that have their own power source and can actively emit radio waves (tuned to a radio frequency electromagnetic field) that contain electronically stored information that can be identified within a few meters. Unlike bar codes, radio frequency tags do not need to be in the line of sight of the identifier, but can also be embedded within the object being tracked. The frequencies of the RFID commonly used today are mainly 135KHz, 13.56MHz, 43.3-92MHz, 860-930MHz, 2.45GHz and 5.8GHz, and the reading distance and the reading speed of the radio frequency signal increase with the increase of the RFID frequency, so the frequency used by the radio frequency transponder and the radio frequency reader in this embodiment is 2.45GHz or 5.8GHz, so as to perform the identity authentication more conveniently and quickly.

It should be understood that, because the radio frequency transponder and the radio frequency reader also have a positioning function, in this embodiment, the radio frequency transponder may also be installed on the experimental apparatus to perform real-time positioning on the important item. The radio frequency reader comprises an RSSI register, and the radio frequency information processor can read the signal strength of the radio frequency reader when receiving the data packet from the radio frequency transponder in the RSSI register and judge the distance between the radio frequency transponder and the radio frequency reader according to the signal strength. The embodiment can use the function to monitor the position of the experimental device, and can also control a processing chip or other external control chips of the radio frequency module to send distance prompt information to the server 13 when the distance is greater than or less than a certain preset threshold value, so as to determine the corresponding place of the experimental device. Specifically, for example, the radio frequency transponder of the experimental device a sends a radio frequency signal to a radio frequency reader installed in the laboratory, and when the radio frequency transponder is carried away by an operator by more than five meters from the laboratory during operation, the distance between the radio frequency transponder corresponding to the radio frequency signal strength read by the RSSI register and the radio frequency reader is greater than a preset threshold value of five meters, then distance prompt information is sent to the server 13, so that a monitoring worker can grasp the information in time, and the safety of the laboratory and the experimental device is enhanced.

It should be understood that the server 13 in the present embodiment may be a computer, a smart terminal, a cloud processor, or other electronic devices with data processing and logical operation functions.

It is clear to those skilled in the art that, for convenience and brevity of description, the specific working process of the apparatus described above may refer to the corresponding process in the foregoing method, and will not be described in too much detail herein.
