[0002] During the operation of the smart substation, in order to ensure the safe operation of the relay protection device, it is necessary to test the relay protection device regularly to ensure that the relay protection device operates accurately after reaching the set value, so as to avoid major electrical accidents caused by the action value of the relay protection device not matching the set value.
[0003] During the entire test process, each person needs to be assigned a task first, and then manually record and sign in. This manual record not only leads to inefficiency of the entire test process, but also causes the phenomenon of signing in on behalf of others. Therefore, it is particularly important to identify the identity of the verification personnel, so that the operation process can be standardized and responsibilities can be clarified to the greatest extent. Summary of the invention
[0004] The object of the present invention is to provide a relay protection tester based on fingerprint recognition, which can identify the verification personnel and record the verification personnel's identity information;
[0005] In order to achieve the above object, the technical solution adopted by the present invention is:
[0006] A relay protection tester based on fingerprint recognition includes a tester body, a fingerprint collection module and a control module.
[0007] The fingerprint acquisition module is installed on one side of the tester body, and is used to collect fingerprint information and send the fingerprint information to the control module; the control module is used to receive the fingerprint information and compare the fingerprint information with the stored fingerprint information. If the comparison is correct, the correct comparison information is sent to the test processor of the tester body, and the information of the verification person to whom the fingerprint information belongs is recorded at the same time; the test processor is used to unlock after receiving the correct comparison information.
[0008] Preferably, the tester body is communicatively connected to a relay protection verification management main station, and the test processor is used to obtain a relay protection device verification scheme from the relay protection verification management main station.
[0009] Preferably, the test processor is also used to record the values of voltage, current and switching quantity injected into the relay protection device during verification of the relay protection device, record the response process of the action node opened by the relay protection, match the recorded data with the verification personnel information belonging to the fingerprint information, and send it to the relay protection verification management main station.
[0010] Preferably, a handle is installed on the tester body; a contact sensor is embedded on the inner side of the handle, wherein the position of the contact sensor corresponds to the position where the verification personnel grasps the handle; the contact sensor is electrically connected to the test processor, and after the contact sensor is touched, the contact sensor sends a locking signal to the test processor; the test processor is locked after receiving the locking signal, and the verification personnel is required to place the fingerprint on the fingerprint collection module again to collect the fingerprint, and the control module compares the fingerprint information with the stored fingerprint information. If the comparison is correct, the correct comparison information is sent to the test processor of the tester body, and the verification personnel information to which the fingerprint information belongs is recorded at the same time. If the verification personnel information to which the fingerprint information belongs is different from the verification personnel information last time, it is uploaded to the relay protection verification management main station.
[0011] The present invention uses a fingerprint collection module and a control module to identify the fingerprint of the verification personnel and record the verification personnel information to which the fingerprint information belongs, thereby improving work efficiency and security, effectively preventing unauthorized personnel from operating, avoiding the occurrence of phenomena such as proxy signing, and greatly improving the reliability of this process.
[0012] In the present invention, the relay protection tester is communicatively connected with the relay protection verification management main station, and is used to transmit the relay protection verification scheme, the voltage, current, and switch quantity values injected into the relay protection device when verifying the relay protection device, the response process of the action node opened by the relay protection, and the identity information of the verification personnel to the relay protection verification management main station, thereby ensuring the stability and controllability of the verification process and eliminating the influence of human errors. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a schematic diagram of the structure of the present invention. DETAILED DESCRIPTION
[0014] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.
[0015] like Figure 1 As shown, the present invention is a relay protection tester based on fingerprint recognition, comprising a tester body 1, a fingerprint collection module 11 and a control module.
[0016] The fingerprint acquisition module 11 is installed on one side of the tester body 1, and is used to collect fingerprint information and send the fingerprint information to the control module; the control module is used to receive fingerprint information and compare the fingerprint information with the stored fingerprint information. If the comparison is correct, the correct comparison information is sent to the test processor of the tester body 1, and the verification personnel information to which the fingerprint information belongs is recorded at the same time, wherein the control module is electrically connected to a storage module, and the storage module stores the fingerprint information of the verification personnel collected in advance; the test processor is used to unlock after receiving the correct comparison information. After unlocking, the data between the various test modules in the tester body 1 can be received, processed and sent to complete the test work. Through fingerprint recognition, the verification personnel do not need manual recording and signing in, and can be recorded in the background, which improves work efficiency and safety, effectively prevents unauthorized personnel from operating, avoids the occurrence of phenomena such as signing on behalf of others, and greatly improves the reliability of this process.
[0017] Furthermore, the tester body 1 is communicatively connected with the relay protection verification management main station, wherein the relay protection tester can be equipped with a wireless uplink port, and the test processor is used to obtain a relay protection device verification scheme suitable for the local power grid from the relay protection verification management main station, that is, the voltage, current, and switch quantity values injected into the relay protection device during verification, record the voltage, current, and switch quantity values injected into the relay protection device during verification, record the action node response process opened by the relay protection, match the recorded data with the verification personnel information belonging to the fingerprint information, and send it to the relay protection verification management main station, thereby ensuring the stability and controllability of the verification process and eliminating the influence of human errors, wherein the relay protection tester and the relay protection verification management main station are configured with a network communication security scheme, and the communication between them adopts encryption technology and "two-way" identity authentication technology to ensure that the communication between the two parties is credible, such as: power Internet of Things technology, to solve lightweight and reliable communication in scenarios where network communication has delays and unstable communication.
[0018] Furthermore, a handle 12 is installed on the tester body 1; a contact sensor 121 is embedded inside the handle 12, wherein the position of the contact sensor 121 corresponds to the position where the inspector grasps the handle 12, and the contact surface of the contact sensor 121 protrudes from the handle 12; the contact sensor 121 is electrically connected to the test processor, and when the test is completed, the inspector lifts the handle 12, the contact sensor 121 is contacted, and the contact sensor 121 sends a locking signal to the test processor; the test processor is locked after receiving the locking signal, and the inspector needs to place the fingerprint on the fingerprint collection module 11 again to collect the fingerprint, and the control module compares the fingerprint information with the fingerprint collection module 11. The stored fingerprint information is compared. If the comparison is correct, the correct comparison information is sent to the test processor of the tester body 1. At the same time, the verification personnel information to which the fingerprint information belongs is recorded. If the verification personnel information to which the fingerprint information belongs is different from the verification personnel information of the last time, it is uploaded to the relay protection verification management main station. The contact sensor 121 is used to detect whether the verification personnel has moved the tester body 1. When the fingerprint recognition is required again on the mobile tester body 1, if the fingerprint recognition is inconsistent with the last fingerprint recognition, it is uploaded to the relay protection verification management main station to detect whether there are other verification personnel using this relay protection tester, clarify the operation responsibility, and avoid other verification personnel signing on behalf of others.
[0019] The method of using the present invention is as follows: when performing the test work, the power of the relay protection tester is first turned on, and the verification personnel performs fingerprint recognition, and the fingerprint information of the control module is compared with the stored fingerprint information. If the comparison is correct, the correct comparison information is sent to the test processor, and the verification personnel information to which the fingerprint information belongs is recorded at the same time. The test processor is unlocked after receiving the correct comparison information, and the verification personnel downloads the verification scheme from the relay protection verification management main station, that is, the values of the voltage, current, and switch quantity injected into the relay protection device during the verification, and clarifies the measured parameters. The relay protection tester is connected to the relay protection device to be tested, and relevant tests are performed. After the test is completed, the actual value of the measured parameter is compared with the set value to ensure whether the relay protection device operates correctly under the specified conditions, and a test report is generated. After the test is completed, the power of the power amplifier is turned off. When it is necessary to test other nearby relay protection devices, the verification personnel lifts the handle 12, and the contact sensor 121 is touched. Only after the fingerprint is recognized, can the relay protection tester be used. At the same time as the fingerprint is recognized, the relevant data will also be saved and uploaded to the relay protection verification management main station.
