Description
Technical field
The invention belongs to electronic guide technical field, be specifically related to a kind of variation based on the intelligent electronic guide system of wireless sensor network and method。
Background technology
Intelligent electronic guide system includes main frame and from two parts of machine, and wherein main frame is supplied to guide's use, is supplied to visitor from machine and uses, and completes the standardization of intelligence visitor management, wireless speech explanation and commentary。Main frame is made up of microprocessor, wireless digital radio-frequency (RF) receiving and transmission module, FM FM transmission module, display alarm module, Keysheet module and MCI；It is made up of from machine microprocessor, wireless digital radio-frequency (RF) receiving and transmission module, FM FM reception module, display alarm module, Keysheet module and earplug。
Guide explains orally input FM FM transmission module after the MCI of main frame gathers, and then launches；Receiving FM signal from the FM reception module of machine, earplug is arrived in output。Record has the CD of canonical solution excuse, recorder or MP3 can be input to main frame by standard interface, is launched by the FM FM transmission module of main frame, it is achieved the standardization of commentary。And the network that the FM FM transmission module of slave and receiver module form is that wireless speech explains orally network。Main frame is often arranged in box body。
And on the other hand, the microprocessor of main frame often constantly heats up at run duration, but the microprocessor of main frame lacks cooling device and in the short time, the temperature of its own cannot be lowered, thus the temperature of micro making main frame is exceeded normal working temperature, thus can result in the performance of the microprocessor of main frame and reduce with efficiency。Additionally prevent particulate matter invasion and attack bad with antistatic property。
Additionally up to now in a fairly large number of situation of guides, some guides need real-time to carry out audible communication, thus need to combine input FM FM transmission module after the MCI of main frame gathers, then launch, thus can be achieved with for the on-the-spot audio-frequency information gathered of guide to carry out audible communication, but the increase of demand of the audible communication along with some guides, once occur that a large amount of guide's real-time synchronization ground carries out audible communication, often will interfere, at all can not the audio frequency specifically conducted a sightseeing tour of identification so that audible communication cannot realize。
In order to solve this problem, allow for guide and carry out audible communication by using alone the MCI of main frame to gather, result in the problem that the MCI of the main frame service efficiency gathered is not high, although in order to solve this problem, also background terminal it is proposed to be operated transmission and the reception of audio signal, so often allow so that the semaphore of transmission increases, affect the efficiency of transmission of transmission line；Additionally because of the delayed distortion being likely to produce audio signal of transmission line。
Summary of the invention
It is an object of the invention to provide a kind of variation based on the intelligent electronic guide system of wireless sensor network and method, it is to avoid prior art lacks cooling device and the temperature of its own cannot be lowered, make the temperature of micro of main frame in the short time beyond normal working temperature, the defect that the performance of the microprocessor of main frame and efficiency will be caused to reduce, prevent particulate matter invasion and attack bad with antistatic property；
Input FM FM transmission module after this time can use the MCI of main frame to gather audio-frequency information of conducting a sightseeing tour just can be identified in time additionally by this invention, then launch and carry out audible communication, make to there is no need to be intended to the request allowance of same background terminal when needs audible communication and can carry out audible communication, thus can improve the efficiency of transmission of transmission line, and allow guide can obtain the reaction of correspondence after obtaining main frame in time。
In order to overcome deficiency of the prior art, the invention provides the solution of a kind of variation intelligent electronic guide system based on wireless sensor network and method, specific as follows:
A kind of variation is based on the intelligent electronic guide system of wireless sensor network, and including main frame with from two parts of machine, wherein main frame is supplied to guide's use, is supplied to visitor from machine and uses；Main frame is made up of microprocessor, wireless digital radio-frequency (RF) receiving and transmission module, FM FM transmission module, display alarm module, Keysheet module and MCI；It is made up of from machine microprocessor, wireless digital radio-frequency (RF) receiving and transmission module, FM FM reception module, display alarm module, Keysheet module and earplug；
