GB/T 43993-2024Urban public facilities - Electronic fence system - Operation specification (English PDF)

3 Terms and definitions

3.1 electronic fence system: an urban public facility management system that applies information technologies such as multiple moving target detection, face recognition and intelligent analysis, combines smart sensing devices with mobile patrol, and provides early warning, tracking, alarm and multi-level coordinated handling for people, vehicles, objects and other targets entering a controlled area.

3.2 operation: the inspection and maintenance, scheduled servicing, fault handling and similar work carried out on an electronic fence system.

3.3 remote inspection: checking the functional state of the equipment of an electronic fence system without going on site. 3.4 on site inspection: checking the physical state and the functional state of that equipment on site.

4 General

The operating architecture, shown in Figure 1, holds operating resources, operating services, and operating evaluation and improvement.

Operating resources provide the underlying support that the operating services need, and cover handover and takeover, the rule system, equipment management, personnel management, emergency management and intelligent management.

Operating services apply different operating modes according to the object served; the modes are inspection and maintenance, scheduled servicing, fault handling and data management, and the objects are the front-end sensing layer, the information transmission layer and the business processing layer.

Operating evaluation and improvement makes improvements on the strength of the evaluation of resources and services, so that the system keeps receiving sound operating service.

The establishment of operating resources follows the principles of completeness, compliance, suitability and effectiveness. The operating services safeguard reliable, efficient, stable and secure running of the system. Operating evaluation and improvement follows the principles of objectivity, fairness, soundness and completeness, and service quality is improved continually on the strength of the evaluation results.

5 Operating resources

5.1 Handover and takeover. The electronic fence system shall be put into operation only after the works have passed completion acceptance. The builder shall confirm the state of the system and its equipment and then hand the operating work over to the service provider. On taking the system over, the service provider shall obtain the complete records produced during construction.

5.2 Rule system. An organisational structure shall be set up and responsibility rules drawn up for each body and post. Equipment management rules shall be drawn up, covering the equipment ledger, operating procedures, the fault handling plan and spare parts. Safety management and fire management rules shall be drawn up.

5.3 Equipment management. An equipment ledger shall be kept, recording the running state of the equipment and its inspection, maintenance and servicing; the records shall be complete and accurate. Equipment operating procedures and instructions shall be drawn up so that operation is disciplined. A fault handling plan shall be drawn up, covering the grading of fault events and how each is to be met. A spare parts store shall be set up, holding equipment that commonly fails and consumable parts.

5.4 Personnel management. Posts shall be set up according to the operating need, with responsibility rules for each post covering duties, workflow and operating procedures. Staff shall receive post skills training and shall pass an assessment before taking up the post. They shall respond promptly to what happens on site and deal with problems on their own initiative. They shall observe the post responsibility rules and query and monitor the system in real time as required.

5.5 Emergency management. An emergency management body shall be set up and the necessary emergency equipment, apparatus and supplies provided and checked regularly so that they stay in good order. A single emergency command centre shall be set up to command and coordinate the handling of incidents. Emergency plans shall be drawn up and exercised regularly. Once an emergency occurs, the plan shall be activated as prescribed and measures taken to stop the situation spreading.

5.6 Intelligent management. An intelligent management platform should be set up to suit the needs of the operating resources and services, with functions such as service dispatch, tracking, recording and statistical analysis. The running state of the subsystems and equipment of the front-end sensing, information transmission and business processing layers should be monitored according to their characteristics. An operating database should be set up for judging system state and predicting faults and for providing predictive inspection schemes. The quality indicators of the operating service should be monitored, including at least the mean event response time, the event response rate, the mean fault repair time, the on-time fault repair rate, the equipment fault rate and the completeness rate of documents and records.

6.1 Service flow

The operating service shall be carried out in the following flow.

A work plan for remote inspection, on-site inspection and scheduled servicing is drawn up from the scale of deployment, the equipment and the user's needs.

Remote inspection is used to view the functional state of the equipment, and the equipment state and any operating problems are recorded.

The on-site inspection route is planned by reference to the remote inspection record, and the operating problems found remotely are given particular attention.

On-site inspection is used to view the physical and functional state of the equipment, and the inspection is recorded, including at least the location of the work, the equipment model and number, the equipment state and the fault found.

During inspection and maintenance the logs generated automatically by the equipment are queried and collected, and the equipment state judged from them, as a basis for scheduled servicing and fault handling.

Scheduled servicing keeps the equipment in good running order and lengthens its service life, and may be combined with on-site inspection.

When the system develops a fault, the fault is analysed and dealt with under the fault handling plan, drawing on the inspection and maintenance records and the equipment logs.

6.2 Inspection and maintenance

7 Operating evaluation and improvement

7.1 Operating evaluation may be organised by the service provider, by the owner or by a third-party body engaged by the owner. A full evaluation shall be carried out at regular intervals, once a year being recommended.

The content of the evaluation shall meet Table 1, which has three columns: evaluation indicator, evaluation requirement and evaluation method. Under the heading of operating resources it lists handover and takeover, the rule system, equipment management, personnel management, emergency management and intelligent management; under the heading of the discipline of the service it lists the service flow, inspection and maintenance, scheduled servicing, fault handling and data management. Each indicator is required to meet the subclause of the same title, that is 5.1 to 5.6 and 6.1 to 6.5 in that order, the requirement on intelligent management being a should and all the others a shall. The evaluation method column is a single merged cell stating that the service provider, the owner or the third-party body chooses the method to suit the needs of the project and the character of the indicator, and may either attend the site to inspect and appraise or work off site by consulting records through video surveillance, statistical returns and the like.

The evaluation shall be carried out in the following flow: the object of evaluation is set as the service provider; the method and content are chosen and an indicator system set; an evaluation scheme is drawn up stating the purpose, the scope and the members of the evaluation team; the evaluation is carried out under the scheme and the indicator system, with data gathered and scores assessed; and the result is formed.

The service provider should apply the result to performance appraisal, reward and penalty and to improvement work. The owner should use the result to supervise the service provider and to press for continual improvement.

7.2 Continual improvement. The service provider shall organise improvement work on the strength of the evaluation result, remedy the shortcomings found during operation, revise and optimise the operating management plan, offer proposals for continual improvement and raise its operating capability. The measures include at least setting up an improvement mechanism for operating management; holding training regularly so that the capability of the organisation and its staff keeps rising; summarising and analysing operating behaviour that does not meet the rules; investigating and analysing the reasons why operating indicators were not met; drawing up improvement measures and plans from that analysis; and carrying out the improvement, monitoring, reviewing and recording the process and the result according to plan.
