Block direct effect pair as if outside detonator, control are ignited the sufficiently large electric current of functional module output and carry out detonating primer.Security
It is the characteristic particularly paid close attention in fuzing system, armament design with validity, therefore, should ensure output current in functional module is ignited
Can detonating primer, prevent again do not have ignite order when module maloperation, this is in actual applications very fatal
's.
To prevent igniting the danger that functional module maloperation brings, in the design, the embodiment uses Sources controlling, divides
Level, multinode control provide safeguard come the safe operation to circuit.
When a failure occurs it, even if a certain switch misoperation conducting, other switches remain able to cut-off loop, return work
Road is in off state, and detonator cannot be detonated.
Step 4, carry out power module design：
Because field controller 2 needs to be arranged close to the place of flashpoint according to actual needs, therefore will be as far as possible
The light and handy installation that is easy to carry, due to the uncertainty of installation site, its power supply selects battery-powered power supply.

Pond group.Lithium battery group charging use and the identical charging chip of remote controllers 5-MP26123DR-LF-Z voltage stabilizing chips, it fills
, up to 24V, charging current is up to 2A for electric input voltage.Because field controller is nearer apart from flashpoint, to control during ignition
The impact of machine processed is larger, and the safe design of circuit includes current limit and Thermal shutdown switch, in fault or other are prominent
Hair event can in time cut off circuit, protection system circuit and battery pack safety when causing electric current excessive.
The topmost work of field controller is detonating primer, and detonating primer needs to meet some requirements, i.e. detonator
Enough energy must be obtained, this requires that power supply circuit wants to provide the electricity where the High-current output to detonator of stabilization
Road.Realized using high-power step-up/down chip XL6019 in the present invention, the constant current source power supply circuit being made up of XL6019,
It is 1.22A, maximum output voltage 60V that its output current is permanent.Constant-current source circuit is the direct power supply circuit of cap sensitive, its work
Make the quality of the direct decision device of quality of state.It is the input of constant-current source circuit, enable, defeated so the embodiment is in the design
All control works under CPU to go out end, it is ensured that security, the stability of circuit work.
The present invention also provides a kind of control method of interactive digital wireless remote control initiation system, specifically includes following step
Suddenly：
Step 1, carry out early-stage preparations：Field controller 2 is controlled, it is necessary in advance by field control using many fire point units
Device 2 is put into the fire point specified, and opens field controller 2, and inspection apparatus state, waits remote controllers 5 to send order.
Step 2, startup：The start button of remote controllers 5 is opened, remote controllers 5 are existing by LCD display system electricity
The field connection status of controller 2；The field controller 2 for selecting detonation node by button is communicatively coupled, and anti-receiving
After feedforward information by the presentation of information of field controller 2 on the control panel.
Step 3, arming：Remote controllers 5 open safety button, and interactive digital wireless remote control initiation system is entered
Enter to prepare the state of detonation；After field controller 2 receives insurance releasing order, start to measure the detonator resistance of external connection,
And resistance information is uploaded into remote controllers 5；Meanwhile, 24V detonation potential circuits are enabled, and power supply circuit is in running order.
The field data that remote controllers 5 will be received shows that wait next step is operated in display interface.
Step 4, detonation：Remote controllers 5 open detonation button, and order of detonating is sent to the field controller 2 specified；
Relay is switched to 24V outputs by field controller 2 after receiving detonation order, meanwhile, the outside terminals in connection detonator
24V is exported on son, and is kept for time several seconds, detonator is detonated, disconnect power supply circuit.Field controller 2 is by the state of detonation and certainly
Body feedback of the information shows to remote controllers 5 in remote controllers.
In the embodiment, present invention also offers can using high speed height between a kind of remote controllers 5 and field controller 2
By the communication protocol of property, the precise synchronization for detonating in time is realized by way of logic circuit and software programming.
The embodiment additionally provides a kind of for realizing the control method of interactive digital wireless remote control initiation system
Remote communication method, it is characterised in that：GFSK communication modes are used between field controller 2 and remote controllers 5, by special
IC is realized；AES128 algorithm for encryption is used between field controller 2 and remote controllers 5；Every control that remote controllers 5 send
System instruction is fixed length instructions, and every instruction includes operational order and time series two parts information；Field controller 2 is using interruption
Mode receives instruction, i.e., interrupted after packet has been received；Between remote controllers 5 and field controller 2 communicate when
Between precision be higher than 1ms；The instruction of remote controllers 5 is communicated using repeatedly transmission, the forms of broadcasting with field controller 2, far
Range controller 5 instructs repeatedly to send can ensure that field controller 2 can be reliably received；And the transmission time of control instruction
At intervals of set time T, field controller 2 can go out the time of main frame according to reception interruption time of origin and bag serial number calculation.
After the control instruction broadcast transmission of remote controllers 5, field controller 2 judges certainly according to itself sequence number and the broadcast frame number of instruction
Oneself should be transmitted the timing node of replying instruction, to avoid being collided in communication with other field controllers, reduce
The probability that information makes a mistake, improves the reliability of communication.
By with upper type, it is possible to achieve 1 remote controllers completes once same with 12 field controllers in 100ms
The function of operation is walked, the difference between the field controller of same group on the burst time can be made to be no more than 10ms.
Additionally, remote controllers send broadcasting instructions control method：This instruction needs to specify field controller to reply, or
All field controllers are replied；The broadcasting instructions of remote controllers 5 are fixed length time t, and this time is 10ms in practice, is sent
12 bytes.The transmission that the broadcasting instructions of remote controllers 5 contain a sequence number for frame to mark broadcast frame is sequentially.Positive reason
Under condition, field controller 2 is interrupted when first broadcasting instructions is received, when under distant or signal harsh conditions
First data frame may be lost, until second or the 3rd broadcasting instructions are just received and interrupted.For ease of
Illustrate, what we assumed to receive in the broadcast frame flow chart of Fig. 5 and Fig. 6 is second broadcasting instructions.
Field controller sends response command control method：After field controller 2 receives instruction, according to itself sequence number and
Receive broadcast frame sequence number calculate need wait time, judge whether reach the transmission cycle of oneself, and oneself
The transmission cycle is sent to remote controllers 5 by frame T2 is replied.
Although refer to the attached drawing disclose in detail the present invention, it will be appreciated that, what these descriptions were merely exemplary, and
It is non-for limiting application of the invention.Protection scope of the present invention may include do not departing from this by appended claims
