Field of Invention
The proposed invention generally relates to emergency reporting devices wherein electronics based hardware called “Help Button Unit”, specially designed for tractors (can be implemented in other vehicles too) along with software platform to communicate with a remote control-station ( or a call center) in case of emergency. Said invention employs a GPRS/GSM/GPS module to transmit data-alert, when a customized switch of the said Help-Button, inbuilt within the body/chessy of the said vehicle, is pressed and hold for more than particular delay(preferably 7 seconds) to remote server, capable of enabling voice communication to the said Help-Button device from call centre. The location data is tracked from the remote station using the on-board GSM module/with the service provider.
Background of the Invention
A help button is an electronic device designed to assist in alerting somebody in emergency situations where expert consultation is required. The availability of modern high-speed data processors and the continually growing popularity of the Internet make it desirable to offer an emergency reporting device that is capable of reporting a user's need for emergency help using message sent over the Internet. The proposed invention doesn’t require any internet connectivity for the end user. Said help button is implemented in hardware wherein, a customized switch of the said button is inbuilt within the body/chessy of Tractor, in case of emergency or when an expert advice is required the user press and hold the button for 7 seconds (Selectable Delay) thereafter data is transmitted to the remote server.
Objectives of the Invention
The prime objective of the proposed invention is Electronics based hardware called “Help Button”, designed with software platform wherein the Help button unit is accessed by an appropriate front-end application.
Another objective of the present invention is a GPRS/GSM module to transmit data alert when switch is pressed and hold for more than 7 seconds to remote server, capable of enabling voice communication to device from call center wherein data contains Request generated time, Location details (tower based), Hour meter reading (HMR)/total Vehicle running Hours.
It is an objective of the present invention wherein, if GPRS signal is absent then device need to send captured data/service request to server.
It is another objective of the present invention wherein, device communicates automatically for at least once in a day to server with updated HMR band location details.
Yet another objective of the present invention wherein, the device is automatically disabled for 5 Minutes after generating first service request and maximum two service request are allowed for individual user per day.

Another objective of the present invention is a one way voice communication i.e. from call center to device.

Detail Description of the Invention
The present invention, in general relates to a Help Button Unit with voice feature, wherein a GPS/GSM module transmits data-alert signal when a customized switch of the said Help-Button, inbuilt within the body/chessy of the said vehicle is pressed and hold for more than 7 seconds to remote server, capable of enabling voice communication to the said Help-Button device from call centre.
Said invention consists of a Help Button Unit (HBU) which employs a GPR Sand GSM module to transmit data alert signal with internal antenna in case of emergency or when the user requires expert advice. HBU is accessed through an appropriate front-end application and implemented on the face of housing assembly of the tractor.
Help Button Unit sends a request data to the remote server when switch is pressed and hold for more than 7 seconds, and enables voice communication to device from call center wherein data contains Request generated time, Location details (tower based), Hour meter reading (HMR).
For Hour Meter Reading, the device have internal clock and need to count tractor running Hrs. Hour meter starts when the tractor’s ignition key is in ON state (Voltage level acceptable 3-15V)/with frequency input (0 to 1000Hz);The Hour meter starts counting in two modes:
A) if engine rpm frequency is greater than or equal to 3Hz;
B) if dc voltage is greater than or equal to 3V to maximum of 15Volts;
For both conditions A & B one common input is required.
Wherein, One hour indicated by device HMR is equivalent to one hour indicated by real time clock.
In one exemplary case, if there is GPRS signal failure, the Memory is buffer up for 30 days based on First In First Out (FIFO) concept. And the device needs to send captured data/service request to server.
? In SMS (UDP)(if GPRS coverage is available) Else,
? Immediately after regaining of GPRS signal. (Last two service request with location and request generated time and HMR need to be stored.
? Every 24 hour for 5 minutes with or without ignition (configured in lot wise for communication time frame);
? Instantaneously in case of regaining of network coverage with ignition.

The Device should communicate automatically for at least once in a day to server with updated HMR and location details, and will automatically disabled for 5 Minutes after generating first service request and only two service request are allowed per customer/day after that device shall be deactivated for said calendar day.
Device is enabling with one way communication wherein, call is connected from call center to device. The voice chat has following features:

? The Speaker is capable of enabling voice communication as well as voice commands with audible voice clarity, with low noise capability;
? Speaker output would not be less than 78db
? Buzzer for incoming call/voice command alert, if the speaker output sound not audible in case of field conditions.
? Microphone with low noise capability. Capable of enabling smooth and audible communication to receiver/call center;
? Switch will also act as a call acknowledge button.
? capable of sending voice commands/recorded voices to end user.

Some other features of the said device are:
• Rugged connector 3 wire (Automotive grade) for vehicle battery and ignition key input terminal connection with cable length of minimum 100mm
• Features need to be provided for device is reset, in case of abnormalities, if any.
Help Button Unit comprises of Status LED’s
