H41q/H51q系统为CPU四重化结构（Qmr-quadruple modular redundant），即系统的控制单元共有四个微处理器，每二个微处理器集成在一块CU模件上，再由两块同样的CU模件构成控制单元。

黑马安全系统–可编程电子系统（PES）HIQuad系统主要包括H41q和H51q两个系列，它们基于同样的硬件和软件，是第三代经生产实践验证的HIMA PES系统。它能够利用个人计算机进行灵活的用户组态、监测和事件记录，其出色的性能为生产控制提供最安全的控制保障。

黑马安全系统的H41q/H51q系统为CPU四重化结构（Qmr-quadruple modular redundant），即系统的控制单元共有四个微处理器，每二个微处理器集成在一块CU模件上，再由两块同样的CU模件构成控制单元。一块CU模件即构成1oo2d结构，HIMA的1oo2d结构产品就可以满足AK6/Sil3的安全标准。

为了向用户提供的可利用性，采用双1oo2d结构，即2oo4d结构。在冗余结构的情况下，高速双重RAM接口（DPR）使两个单元通讯，从而解决了无故障修复时间限制的难题。其容错功能使系统中的任何一个部件发生故障，均不影响系统的正常运行。

H41q/H51q system for the CPU quadruple modular redundant (Qmr-quadruple modular redundant), that is, the control unit of the system has four microprocessors, each of the two microprocessors integrated on a CU module, and then by two of the same CU module to form the control unit.

Dark Horse Safety Systems - Programmable Electronic Systems (PES) HIQuad systems mainly include H41q and H51q two series, they are based on the same hardware and software, is the third generation of production practice proven HIMA PES systems. It can use the personal computer for flexible user configuration, monitoring and event recording, and its excellent performance provides the safest control guarantee for production control.

The H41q/H51q system of the Black Horse security system is a Qmr-quadruple modular redundant (QMR-Quadruple modular redundant), that is, the control unit of the system has four microprocessors, each two microprocessors are integrated on a CU module, and then two of the same CU modules constitute the control unit. A single CU module forms the 1oo2d structure, and HIMA's 1oo2d structure products meet AK6/Sil3 safety standards.

In order to provide the usability to the user, the double 1oo2d structure is used, that is, the 2oo4d structure. In the case of redundant construction, the high-speed dual RAM interface (DPR) enables the two units to communicate, thus solving the problem of trouble-free repair time constraints. Its fault tolerance function makes any part of the system fail without affecting the normal operation of the system.
