Abstract
A mobile phone with the interphone function includes a mobile phone and an interphone which are two independent parts; the mobile phone could be normally used independently from the interphone; and the mobile phone is an integrated one after equipped with a battery and has the interphone function after equipped with the interphone part. The mobile phone could control an interphone circuit with different interfaces through a control line, the interphone circuit having a UART port and the interphone circuit having an SPI port. In the utility model, the mobile phone sets functions of the interphone so as to avoid the trouble that the interphone is able to be configured by connecting with a computer.
Description
Technical field
The utility model relates to electronic device field, relates in particular to a kind of mobile phone with intercom function.
Background technology
In present social life and the work, more and more used intercom, very big demand has all been arranged in industries such as public security, civil aviaton, waterpower, railway, manufacturing, building, services, compare mobile phone, intercom has the network limits of not being subjected to, and the conversation cost is low, advantages such as one-to-many talking mode.And conventional intercom need connect computer, and pre-installed software could be provided with it.When needs to its frequency, very inconvenient when parameters such as power are provided with.
Summary of the invention
Advantages such as at existing deficiency, the purpose of this utility model is by mobile phone intercom to be set, and can be provided with intercom by mobile phone display screen, and the utility model is simple to operate, cost is low, and is easy to use.
The utility model is achieved by the following technical solution:
A kind of mobile phone with intercom function comprises intercom and mobile phone, is two independent parts, and mobile phone leaves intercom and can also normally use, and adds that battery is a complete mobile phone; Add that intercom is exactly the mobile phone of a band intercom function, described mobile phone and intercom have all been reserved some interfaces, are respectively intercom and connect the detecting pin, and intercom enables pin, supply pin, charging pin, resetting pin, the SPI interface chip selects signal pins, clock pin, data pin.Wherein the clock pin of SPI and data pin can be multiplexed with the input pin and the output pin of UART interface by the GPIO mouth of mobile phone CPU, so just can control the intercom circuit of SPI mouth, also can control the intercom circuit of UART mouth, amplify the type selecting scope of intercom chip.
