Description

      The present invention opens and closes a drawer with an electric lock on the floor head used by a hospital inpatient for storing personal belongings in a hospital bed with a control device of an electric lock built in a TV timer of a pay TV system to store valuables. It is related with the lock management system which provides performing easily.

      Conventionally, inpatients in hospitals store valuables by installing a steel safe in a drawer installed on the bedtop of the hospital bed or attaching a lock to the drawer of the bedtop. The lock used for this is a cylinder lock, a plastic card lock, or a method of matching the password, but a cylinder lock or a plastic card lock requires a spare key in case the key is lost. It is not easy to manage, and PIN numbers often occur when a user forgets the number, which is particularly unsuitable for the elderly.

  In addition, cylinder locks and plastic cards are small in size and are often lost due to daily items such as bedding and floor-to-ceiling. A system with a lock function that locks the platform is devised, and the floor head drawer is used as a safety box, but the IC memory cassette, IC stick memory, and IC card are the keys to the floor head platform. Since the ID signal set in the information storage medium such as a magnetic card is a number fixed to the floor head base, by intentionally copying the information storage medium, The drawer can be unlocked, resulting in a decrease in security.

  The problem to be solved by the present invention is that in hospitals where an unspecified number of people such as visitors come and go, there are many theft cases where suspicious people roam the hospital and steal valuable items of inpatients. It is very difficult for the hospital to manage the valuables of the inpatients because the management of the valuables possessed by the patients is difficult, and the storage management is done at the individual patient's responsibility, Because the equipment for managing valuables is not sufficient and the psychological burden on inpatients is large, a lock management system that facilitates the storage management of valuables for individual hospitalized patients and reduces the psychological burden on inpatients and hospitals. To provide and enhance its security functions.

  In order to solve the above-mentioned problems, the present invention incorporates the function of a lock management system into a pay TV system in which a hospital inpatient uses a TV for a fee, and uses an information storage medium used for TV usage fee settlement as a key. It is characterized by enhancing the security function of the system that controls the electric lock with a microcomputer built in the timer and increasing the added value of the valuables storage function.

  Since the lock system of the present invention does not need to identify the key corresponding to each floor head when installing the floor head, it can be installed sequentially regardless of the order of equipment loading and the room. It is easy to set up a stand and there is no need to manage a spare key, so hospital management is simple, and inpatients to use use an IC memory cassette as a key for payment of TV usage fees. The number of items to be handled is reduced and the burden on the patient is reduced.

  When an in-patient uses the pay TV system to pay in advance with an automatic payment device, the prepaid charge data is recorded in the information storage medium and the lock function of the floor head drawer is activated. An ID signal assigned to each timer is randomly selected by a microcomputer built in the automatic payment machine and recorded in the information storage medium. The ID signal recorded at this time is set so as not to be duplicated in each television timer.

  When the information storage medium on which the password is recorded by the automatic payment apparatus is electrically connected to the television timer, an ID signal is sent from the information storage medium to the television timer, and the information storage medium and the television timer are When the information storage medium is connected to the TV timer, the electric lock attached to the floor head drawer is opened and the connection is released. The electric lock will be tightened, and the drawer on the floor head will have a lock function, making it possible to store and manage valuables.

  Once the information storage medium is connected to the television timer, an ID signal pre-assigned to the television timer for preventing the information storage medium from being used by another television timer is When the information storage medium is sent to the information storage medium and recorded, the electric lock connected to the other television timer is activated by the ID lock signal even if the information storage medium is connected to the other television timer. I can't.

  When the usage fee of the information storage medium decreases using a TV or refrigerator, the automatic payment device can repeatedly pay the usage fee, but the ID signal is changed even if additional payment is made The function of the key of the lock can be continuously maintained without any problem.

  When an inpatient is discharged, if the information storage medium is connected to the automatic checkout device, it will be refunded if there is a remaining usage fee, and an erasure signal for erasing the TV timer ID signal will be stored on the information storage medium. When the information is recorded and the information storage medium is returned to the television timer and electrically connected, the lock function ID signal of the television timer is erased and returned to the initial state. Similarly, when there is no balance in the information storage medium, the ID signal is erased, and when a new hospitalized patient pays a usage fee with an automatic payment machine and connects the information storage medium to the television timer, The drawer on the floor head has a lock function and can store valuables.
