Wherein, master control set comprises first signal transceiver module 12 and processing module 11, everyIndividual measurement mechanism comprises secondary signal transceiver module 23, apart from detection module 21 and electric field detection module 22.
Distance detection module 21 in measurement mechanism 20 for to and around between the distance of object carry outMeasure, and generate the distance signal of this distance of reflection. Wherein apart from being provided with ultrasonic wave in detection module 21Distance measuring sensor, measures itself and periphery object distance for the mode by ultrasonic ranging. ElectricityField detection module 22 detects for the electric-field intensity of its environment of living in, and this electric-field intensity of output reflectionField intensity signal. Wherein electric field detection module 22 comprises electric field intensity measuremenrt sensor, due to transformer stationSpread all over high voltage alive equipment with power plant, therefore by detecting effectively judging distance high pressure belt of electric-field intensityThe distance of electricity equipment.
Secondary signal transceiver module 23 is for by distance signal and electric field measurement mould apart from detection module outputPiece obtains field intensity signal and sends to master control set 10 by communication.
Master control set 10 receives the secondary signal in measurement mechanism 20 by its first signal transceiver module 12The distance signal that transceiver module 23 sends and field intensity signal, and this distance signal and field intensity signal are outputed toProcessing module 11. Because this distance signal carries the reflected measurement device distance letter of the distance of object aroundBreath, and this field intensity signal also carries the electric-field intensity information in reflected measurement device environment of living in, thereforeProcessing module 11 can get above-mentioned that measurement mechanism obtains by receiving this distance signal and field intensity signalDistance and electric-field intensity.
Processing module 11 is receiving after distance signal and field intensity signal, by distance wherein and default distanceCompare from threshold value, and electric-field intensity and default field intensity threshold value are compared simultaneously. When this distanceBe less than and when this distance threshold or electric-field intensity are greater than field intensity threshold value, represent the arm of lifting appliance or hang thingObject around distance or the distance of high voltage alive equipment are less than safe distance, now send in time anxious stoppingControl signal.

For first signal transceiver module12, after communicating interrupt 50ms, jump at once next channel transmission information and attempt recovering communication, asFruit is not received replying of secondary signal transceiver module 23 in 3ms, continues to jump that next channel sends again etc.3ms is also Infinite Cyclic.
Because selected 2.4G frequency range communication bandwidth is higher, can realizes up to the baud rate of 2Mbit/S and carrying outCommunication, therefore sends consuming time very shortly substantially can ignore. (70ms) enough main frames in a listening period70/3=23 channel of frequency hopping traversal, that is to say, if only divide 23 channels, both are again with frequentlyThereby the chance of recovering communication just there will be once in a listening period 70ms. So, even by withUnit frequency disturbs, and also can on a glitch-free channel, recover communication very soon, and at this moment frequency hopping finishes, straightTo disturbed interruption again.
About frequency hopping list, in the time that certain channel is disturbed, the disturbed probability of its adjacent channel is the highest,In order to recover as early as possible communication, we can jump to as far as possible away from Last channel, so can be by thisPrinciple is formulated frequency hopping list.
In addition, the power-supply device in measurement mechanism can comprise battery and wireless charging circuit, thereby makes to measureDevice can utilize outside wireless charger to charge to it, without peripheral hardware charging connector, therefore canMeasurement mechanism is made to the hermetically sealed overall structure of water proof and dust proof, thus can be in this evil of hoisting constructionIn bad external environment condition, normally work.
