Embodiment Construction
[0010] The present invention will be further described below in conjunction with drawings and embodiments.
[0011] The emergency call device is composed of two parts: a wireless radio frequency remote controller and an emergency call transmitter. Use the radio frequency remote control to control the emergency call transmitter, and use the telephone line to send the emergency call information by calling.
[0012] It is a small pendant that integrates the radio frequency transmitter remote control and the house door key, just like the current fashionable car remote control key, and can be carried around very conveniently. When needing help, the party presses the help button on the radio frequency remote control, and the integrated chip integrated with the RF transceiver circuit and the single-chip microcomputer detects the sending signal through the input terminal, and immediately sends a radio frequency of a certain frequency to the space through the transmitting antenna coil....

The invention provides an emergency call device. The emergency call device comprises a radio frequency remote controller and an emergency call transmitter, wherein the radio frequency remote controller comprises a first single chip microcomputer with a RF (radio frequency) transceiving circuit, a radio-frequency transmitting antenna, a first EEPROM (electrically erasable programmable readonly memory) program memory, a distress button and a button cell; and the emergency call transmitter comprises a speech chip, a DTMF (dual tone multiple frequency) sending and receiving device, a second EEPROM program memory and a second single chip microcomputer with a RF radio frequency transceiving circuit. The emergency call device has the advantages that: a telephone of a management center of a residence community is dialed by the DTMF sending and receiving device; prestored distress information content is sent by the speech chip; and the emergency call transmitter is connected with telephone wires which nearly all households have. When the radio frequency remote controller is excited, the telephone of the management center of the residence community is automatically dialed, and emergency call information is sent out. The radio frequency remote controller can be manufactured into a small pendant and is extremely convenient for the elderly to carry.
Description
technical field [0001] The invention relates to an emergency call device, in particular to an emergency call product combining wireless radio frequency remote control technology and telephone communication technology. Background technique [0002] Due to the implementation of the one-child policy in our country, the whole country is currently developing towards an elderly society. More and more families have the phenomenon of "empty nests", and there are more and more elderly families living alone, and they are developing towards aging. Residential district construction and the daily management of residential quarters in the city are also aware of this situation now. In residential construction, access control management systems are usually designed and arranged, and emergency alarm buttons are installed in bedrooms and other places. When encountering an emergency, you can press the emergency alarm button to send a distress signal. General residential community management ...
