Abstract

The utility model relates to a special field electronic warning system which comprises a transmitting device and a receiving device, wherein the transmitting device adopts a portable short-range wireless fixed-frequency transmitter, and is installed on a vehicle for police affairs, and the receiving device is a wireless fixed-frequency receiver, is installed on a vehicle for civil use, and can be used through integrating with a safety driving recorder, a GPS locator and a vehicle-mounted radio, the transmitter and the receiver adopt a special frequency band appointed by public security department as a universal carrier wave for the transmitter and the receiver. When in use, workers can start a signal transmitting device after the vehicle for police affairs arrives at the field, the transmitting device can transmit different early warning signals for surrounding regions according to the distance of the field. After the vehicle for civil use enters the early warning range, the receiving device on the vehicle can immediately receive the early warning signals transmitted by the vehicle for police affairs, and can receive different warning signals owing to different distances, therefore drivers can recognize abnormal conditions in forward roads. The special field electronic warning system has simple structure, convenient use, reliable function and low cost, and is suitable for policy-related installation and application.

Description

Special on-the-spot electronic alarm system

Technical field

The utility model relates to a kind of electronic alarm system, in particular for the scene of a traffic accident or guard against the special on-the-spot electronic alarm system in place especially.

Background technology

Along with the development of economic society, highway communication is flourishing day by day, and vehicle is more and more on the highway, and the speed of a motor vehicle is more and more faster.In this case, for special scenes such as traffic accident situ, road maintenance, the temporary parking of fault vehicle, shoofly blockades, if the vehicle that travels can not get clear and definite caution in time, road traffic accident or traffic jam take place easily, especially expressway traffic accident scene, continuous rear-end collision occurrence probability is higher under the inclement weather.

According to statistics, 2008,265204 of road traffic accidents took place in the whole nation altogether, caused 73484 people's death, 304919 people injured; On March 19th, 2009, especially big second accident takes place with Fangzheng County, three highway Harbin is domestic, cause 19 people's death, 27 people are injured.

China takes manually to place triangle reflection alarming board, reflective cone calibration method in recent years to the prevention technique of second accident always at present, and this method warning function is limited in scope, and does not have the effect that well gives warning in advance; In addition, in particular surroundingss such as highway, misty rain ice and snow weather, the work itself of placing warning sign is exactly a kind of potential safety hazard.Though have correlation techniques such as highlighted triangle warning plate, hand-held flashing light to occur,, do not have effectively to contain the generation of second accident because DeGrain does not all obtain general application.

Summary of the invention

The utility model overcomes the deficiency that above-mentioned technology exists, a kind of special on-the-spot electronic alarm system is provided, the electronic technology of utilizing described electronic alarm system realize to special scene give warning in advance, multistage early warning, thereby the generation of effectively pre-preventing secondary accidents and traffic jam.

The purpose of this utility model is achieved in that special on-the-spot electronic alarm system, comprises emitter, receiving device two parts composition, and wherein, emitter adopts portable short-distance wireless frequency transmitter surely, and emitter is contained in police service with on the car; Receiving device is wireless fixed receiver frequently, is installed on the civilian vehicle, also can integrate use with safe driving recorder, GPS orientator, vehicular radio sound equipment etc.; Transmitter and receiver use unifies a special-purpose frequency range of appointment by public security department, and as transmitter and the general carrier wave of receiver, this frequency range is not disturbed with the device of civilian or commercial use, in order to avoid the reduction result of use.When the utility model uses, after the police service vehicle is reached the spot, the staff is the enabling signal dispensing device just, emitter is to the different early warning signal of on-the-spot peripheral region emission, early warning is divided into urgent early warning, relative early warning and three ranks of prompting forecast according to the difference apart from on-the-spot distance, and is also different to the early warning signal that different pre-police regions sends.After civilian vehicle enters early warning range, receiving trap will be received the early warning signal that police car sends on the car, different with on-the-spot distance, the alarm signal of receiving is also just different, the driver is according to the signal regulation of the unified regulation of traffic department, just can identify the place ahead how far the road in the scope abnormal conditions appear, thereby in time take measures, avoid traffic accident or the generation of traffic jam situation.

Of the present utility model have a suitable effect:

(1) emitter is installed in portable reflective cone mark, triangle reflection alarming board and the roadupkeep Guide vehicle, launches multiple signal and make receiver identification, as: the sealing of left and right road; The place ahead accident; Road closed please detour; Traffic controller ahead please detour; Charge content such as take care in the place ahead can be provided convenience for driver and crew more accurately;

(2) with the transmitter civil nature, on the normal domestic vehicle, also can use, use same or another frequency range of Ministry of Public Security's appointment, directly transmitter is installed on the vehicle or integrated with present triangle warning plate, break down or during accident at vehicle, directly open this device, then can shorten the time that starts caution, further reduction accident odds;

(3) transmitter and receiver are all integrated with GPS (GPS), comprise on-the-spot positional information in the signal that sends, then more help receiving garage direction and the geographic position of vehicle, accurately calculate on-the-spot distance and direction, thereby make caution more targeted according to oneself.

The utility model is simple in structure, and is easy to use, and reliable in function is with low cost, and is low in energy consumption, and this national difficult problem of generation that reduces second accident is had positive effect, and suitable policy is installed and promoted.

Wherein: 1, emitter 2, receiving trap

Embodiment

Embodiment: as shown in the figure: emitter 1 is installed on police vehicle, emitter 1 is the square box of 150mm*100mm*30mm, similar police uses vehicle-mounted warning horn, it directly can be integrated in the warning horn during volume production, or installation need be designed to other independently appearance styles; Receiving trap 2 is installed on civilian vehicle, and receiving trap 2 is designed to outer appearnce like vehicle mounted MP 3, does not need tuningly, so can be made into arbitrary shape during volume production, perhaps integratedly advances in any vehicle electronic device to go; Emitter 1 uses by special-purpose frequency range of the unified appointment of the Ministry of Public Security, as transmitter and the general carrier wave of receiver with receiving trap 2.After police vehicle is reached the spot, start emitter 1; The peripheral region basis is different with on-the-spot distance, be divided into three different early warning ranges, launch three different capacity signals, after civilian vehicle receiving trap 2 in the scope is received early warning signal, 1. to driver's prompt tone (prompt tone occurs with stacked system) that gives a warning is urgent pre-police region, radius is 500M, and loud rapid alarm vocal music is set; 2. be pre-relatively police region, radius is 1000M, and comparatively loud alarm vocal music is set; 3. be the prompting forecast district, radius is 2000M, and voice suggestion is set.
