 | UT-050 series releasing key supervisor  (click:1864)
       The operation of Microcomputer Safety Interlock System (MSIS) adequately guarantees the safety of electric power production. When a MSIS is in trouble or needs emergency unlocking, an emergency unlocking key can be used. However, there have not been good methods for managing emergency unlocking keys, which are apt to cause misoperation. Therefore, Unitech developed UT-050 series unlocking key supervisor, which solves the above problem in a good way. UT-050 can manage electric unlocking keys, mechanical unlocking keys, smart unlocking keys, and step-skipping keys. The user uses non-contact radio frequency (RF) IC cards, computer network log-in, or mobile phone short messages as the door-opening tools to obtain the unlocking key for operation. Through the advanced photoelectric detecting technique, the system precisely records the date and time when the user borrows or returns the key. The records are in details and accurate, thus greatly reducing the trivialities caused by manually managing such device. So, it is a good helper of MSIS.
◆ Access and recording function: The cyclic overlay storing mode is used to store the operation of the user. The records are accurate, and the capacity is large. More than 10000 operation records can be stored;
◆ Function of browsing through the access records: Large-screen industrial graphic LCD (160× 80 mm), full-menu user operation interface, and visual and convenient operation;
Function of setting multi-level user authority: Three different levels such as super level, general level, and so on of user authority can be set, and the operation depends on the authority;
◆ Non-contact card user management: Advanced non-contact cards are used as the door-opening tools. The user can set the authority of the user card and add or delete authorized cards by itself;
◆ Data communication interface function: Providing a serial port, the system can transmit the operation records and user settings to other pieces of equipment for use;
◆ Power failure protection clock calendar: Lithium batteries are used to supply power. When the power supply fails, the clock can continue to operate accurately. The super user can set and modify the date and time;
◆ Non-contact detecting technique: Infrared dynamic detecting technique is used to perform on-line detection of the unlocking key. Its use is reliable, and its service life is long;
◆ Full-metal enclosure design: After special anti-rust treatment, the full-metal plastic-coated enclosure is rigid, durable, elegant, and in good taste;
◆ LED lighting system design: With high-brightness LED design, the photo color is bright, and the system is energy-efficient and durable;
◆ Membrane keyboard design: There are 6 membrane keys. Their operation is simple and rapid, and they are beautiful and practical.
Single-machine type:
1) A new user is added through the registration by means of the initial card (senior user card) or the super user password. Only after being registered can a user card (legal card) be used on this supervisor. Each user has a unique user number;
2) Advanced user cards can be used to adjust the time and date of the supervisor and carry out various kinds of setting up like LCD contrast to guarantee that the status setting of the supervisor is correct;
3) When a legal user punches his/her card on the supervisor, the door lock of the supervisor opens automatically. When the user borrows or returns any key equipment in the supervisor, the supervisor will automatically record the user number that opens the door, the borrowed or returned key equipment, and the time. When the door of the supervisor closes, the supervisor will automatically lock the door bolt;
4) At any time, the user can view the historical operation records and browse   them in the inverted sequence of time;
5) When a user card is lost or needs cancellation, a senior user card can delete the user card or re-register a new card.
Network type:
When the network type unlocking key supervisor works with the server software WEBServer, the user can remotely open the key supervisor through a computer in which the WEBServer has been installed on the network and carry out browsing and inquiry on the Web pages. The key supervisor can automatically identify the number of keys and automatically perform interlocking after judging that all the keys have been returned.
The network type unlocking key supervisor uses servers to realize unified management. All the key supervisors within the LAN and the information about the use of their internal keys can be checked in a real-time and on-line way. Accurate recording and statistics of the information about the historical use of the unlocking keys can be carried out, which greatly facilitates the management, statistics, and analysis of the equipment.
Short message type:
Short message type unlocking key supervisor has a built-in communication module, which supports the unlocking in the GSM/CDMA short message authorization mode. A mobile phone registered through the system can remotely control the key supervisor at the station end. The operation process is as follows: The station end user selects, on the key supervisor, the reasons to use the unlocking key and transmits, through the built-in communication module, the information such as the reasons for unlocking to the authorizer’s mobile phone in the form of a short message. After receiving the information, the authorizer will give a written reply to the short message. Then, the user can open the door to get the unlocking key.
