Automatic control system for safety equipment. -Automatiskt styrsystem for säkerhetsanordning.

The invention relates to an automatic control system 5 for security equipment, comprising a portable transmitter unit and a receiver unit placed in a controlled space, with a processor for processing the received data and control outputs for connecting the security equipment to a communication connection with communication and / or alarm devices.

Traditionally, access control, property and health security systems are controlled by a control keypad and / or control switches with the user's own control.

15 Access control usually uses separate devices and various access cards or externally controlled wireless transmitters. In property security systems, the keyboard is used to connect e.g. burglary control on and off. In health safety systems, the control switch is used to control e.g. passivity monitoring at home / away with a switch. Especially in the use of children and the elderly, the above control methods are too demanding and cause unnecessary alarms and restrict the use of safety devices. The main cause of fault alarms in alarm systems is also operating faults 25 in both car alarms and buildings. In addition, building and car security systems require their own operating devices. In access control devices, use is usually limited to controlling access rights.

The object of the invention is to create an automatic control system for safety devices, in which the same control device controls access control, building, health and car safety devices automatically without the user's own control. An automatic location system 35 is also achieved in access control.

101655 2 This object is achieved on the basis of the features set out in the appended claim 1.

What is also new in the control system is that the user needs a single wrist-mounted monitoring device to control all devices, which also enables health monitoring both inside and outside the building. When connected to a mobile phone, it enables a portable security system.

The invention will now be illustrated with reference to the accompanying drawings, in which Figure 1 shows block diagrams of basic units of a security apparatus according to the invention; Fig. 2 shows the connection of a receiver unit included in the apparatus to a mobile telephone; Fig. 3 shows one example of the arrangement of different units of the apparatus in use; and Figure 4 illustrates the use of the hardware in connection with a mobile telephone.

The system according to the invention is constructed of a wrist unit 11 and a receiver unit 12 according to Figure 1. Examples of such units are described in the applicant's patent applications WO 93/16636 (A61B 5/11) and WO 95/07652 (A 61B 30 5/0245). The wrist unit 11 has an alarm button 1, a touch sensor 2 and a microprocessor 3, an encryption unit 4 and a radio transmitter 5, which are implemented by a technique known per se. Since the unit 11 does not necessarily have to be worn on the wrist, it can also be called a portable transmitter unit 35. The receiver and control unit 12 is also constructed of a radio receiver 6, a transmitter 7, an infrasound detector 9, a microprocessor 8 and a control interface 10 implemented in the prior art, as well as software. The receiver and control unit 12 has control outputs 10 for various communication and alarm systems so that it can be connected to their standard interfaces. The receiver-5 and the control unit 12 can be programmed with several structural units 11, whereby it forms a multi-user control system. The ID codes of the structural units 11 of the multi-user control system can be programmed, for example, via an access control system using a standard (10 / RS) 10 serial interface.

The operation of the control system is based on the messages sent by the wrist unit 11, i.e. telegrams, which are protected using known methods, e.g. scrambling 4 and a device-specific ID code. The transmission interval of telegrams is controlled by a random time, when the risk of collision of telegrams is small. Em. by means of telegrams, the receiver and control unit 12 of the control system indicates the presence of the user. The infrared detector 9 detects a low frequency sound generated when the door is opened. Processes The program of the soror 8 detects the opening of the outer or car door by means of the detector 9 and together with the telegrams sent by the wrist unit 11 generates information on whether the user is going in or out of the door. The contact sensor 2 of the wrist unit 11 indicates whether the device is on the user's wrist. Thus, the removal from the wrist 25 switches the wrist unit 11 to a low current state and the information is sent to the receiver, whereby it can be used as alarm information.

For example, when a user leaves an apartment or a car, the infrared sensor 9 receives information about the opening of the door at the same time as the wrist unit 11 sends telegrams. When the telegrams run out when the user leaves the range of the transmitter or wrist unit 11, the program of the microprocessor 8 indicates that the user has left the monitored state.

Em. then the program of the processor 8 turns on the burglary monitoring device 17 and / or sends to the access control system 4 101655 the information that the user has left using either radio frequency or fixed connection for data transmission. Ko. the function can also be used in security systems for the elderly as a time-limited access control for a dementia, which 5 allows free movement on a daily basis, but causes an alarm, for example, at night.

When the user enters a monitored destination, the control system identifies the allowed ID and, if necessary, the opening of the door, and 10 turns off the intrusion monitoring and / or informs the access control or outpatient security system of the presence.

The equipment level of the wrist unit 11 may vary from the basic model of Figure 1 to a model equipped with sensors and software for monitoring health status (cf. the above-mentioned international patent applications).

In connection with the mobile telephone (Figs. 2 and 4), the new control system-20 together with the wrist unit 11 performing health monitoring enables a portable safety system. The control system can be placed in connection with the battery case of the mobile telephone 15 by using the connection points of the accompanying memory of the batteries 13, whereby the processor of the control system simulates the accompaniment memory of the battery and transmits alarm messages to the mobile phone software. The automatic control system connected to the mobile phone can also transmit alarms and other alarms of the car as well as the messages required for real-time monitoring of the connection via the mobile phone network to the control room.

•

The receiver and control unit 12 may be connected to a data acquisition device (e.g., a PC), or to a monitor 18 in a central control room. It may also be connected to a drug dispenser 35 that alerts you if medications are not being taken.

When using the automatic control system according to the invention in home, car and office security systems as well as in connection with a mobile telephone, a whole is obtained, the automatic control of which can be done with one wrist unit.

The system operates in such a way that the automatic controllers according to the invention automatically switch on and off the intrusion monitoring at different locations when the user moves from one destination to another and, if necessary, indicate information about where the user is at any given time.
