For ensureing the safe operation of special equipment, country is to all kinds of special equipments, and from producing, use, all there are strict requirements for three links of inspection, and implementation is the supervision of overall process. Ensure that the important step that special safety equipment uses is exactly the stable operation of its controller. Special equipment controller uses bad environments, and is frequently encountered by strong jamming. There is fluctuation of service in existing special equipment controller, inside connects complexity, broken string, problem of faulty soldering easily occurs, such controller easily goes wrong in running, thus causing special equipment, in use procedure, security incident probably occurs, in order to avoid this situation occurs, it is necessary to develop safe and reliable special equipment controller for above-mentioned situation.

Utility model content

The purpose of this utility model is to solve the problems referred to above, it is provided that a kind of safe and reliable special equipment monitoring system controller.

This utility model be the technical scheme is that a kind of special equipment monitoring system controller for achieving the above object, it is characterized in that: include acquisition module, control module, communication module, FIFO memory, power module, master chip and connector, the outfan of described acquisition module connects the input of master chip, the input controlling module connects master chip, communication module and FIFO memory are connected with master chip, power module respectively with master chip, acquisition module, control module, communication module and FIFO memory individually connect, acquisition module, control module, communication module and power module are connected with connector.

Further, described acquisition module includes 16 A/D chip, overvoltage crowbar, sensor break detection circuit and optical coupling isolation circuit.

Further, described communication module includes serial communication modular and CAN, and described serial communication module includes RS232, RS485 circuit module and optical coupling isolation circuit.

Further, described master chip adopts STM32F105 family chip, and its CORTEXM3 framework has independent instruction bus and data/address bus.

Further, described connector has the electrical connection port for being connected with external equipment.

The acquisition module that this utility model adopts, it can gather (0-20mA/0-5V) analog quantity, differential signal and on-off model, 16 A/D chip gather sampling rate every passage 1000 time/second, and data 100ms updates once, then sends data in master chip; Thering is provided overvoltage protection and sensor burn out detection function during differential signal input, capacity of resisting disturbance is strong; On-off signal passes through optical coupling isolation circuit, and external equipment short circuit is without influence on acquisition module normal operation.

The communication module that this utility model adopts has overcurrent-overvoltage and anti-reverse function, it is possible to allow controller and external equipment carry out data exchange.

The control module that this utility model adopts, have the driving force of 220V10A, output connects delay time less than 10ms, the output off delay time is less than 5ms, output may be used for controlling external circuit, appliance life is more than 100,000 times, and mechanical life, coil and electric shock isolation voltage were 2000vrms more than 20,000,000 times.

The FIFO memory that this utility model adopts, utilizes the principle of first in first out to carry out reading and the storage of data, and continuous print data can be flow to row cache by it, it is prevented that lose data when entering machine and storage operation; FIFO memory can make to get up in data set to carry out, into machine and storage, to avoid bus operation frequently, alleviates the burden of master chip; FIFO memory allows system to carry out dma operation, improves the transmission speed of data.

The power module that this utility model adopts, it is possible to be filtered power supply processing, when line voltage has fluctuation, still can keep the stable operation of other modules of controller, and have overload short circuit to protect, output overcurrent and overvoltage protection.

What this utility model adopted master chip can carry out fetching and data read-write operation simultaneously, improve the runnability of processor, being integrated with nested vector interrupt controller, convenience is the management of interrupt routine and writes, and the design of low-power consumption can make the operation power consumption of master chip be preferably minimized.

So this utility model adopts above-mentioned module and master chip, it is possible to ensure that controller is stable; And controller architecture is simple, it is to avoid because inside connects complexity, it is easy to occur that broken string, broken string, the situation of rosin joint cause the controller can not stable operation.
